Description
CROSS-REFERENCE TO THE RELATED APPLICATION
[0001] This application is a continuation of international
Application No. PCT/JP99/03318, whose international filing date is
Jun. 22, 1999, the disclosures of which Application are
incorporated by reference herein.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a disk device. In
particular, the present invention relates to a disk device adapted
to operate a plurality of disks selectively without using a
detachable magazine.
[0004] 2. Description of Related Art
[0005] FIG. 104 is a schematic cross sectional view showing the
main components of a general conventional disk device adapted to
operate a plurality of disks selectively. FIG. 105 is another
schematic cross sectional view of main components.
[0006] In FIGS. 104 and 105, reference numeral 1 denotes a magazine
loading interchangable disks and 2 is a disk drive section. The
disk drive section 2 comprises a disk motor 3, a disk clamp hub 13
provided on a shaft of the disk motor 3, a disk clamp 4, a disk
roller 6 provided in the magazine 1 and transferring disks 8
transferred from the drive lever 5 driven by a drive means (not
shown) to the disk drive section 2, a drive shaft 9 fixed to a
housing 7 which supports the disk drive section 2, an inclined
plate cam 10 which operates in direction A in the figure and being
driven by the drive means, and a vertical guide plate 11.
[0007] In the above disk device, when extracting (hereafter
selecting) a plurality of disks 8 loaded in the magazine 1, the
drive shaft 9, inclined plate cam 10 and vertical guide plate 11
are respectively displaced. The disk rotation drive section 2 is
displaced in the direction B shown in the figure to determine the
position of the desired disk in the magazine 1.
[0008] Since the type of conventional disk device above arranges a
disk loaded in the magazine 1 and a disk rotating near the disk
drive section 2 in an orientation in which the disks are completely
independent in a planar region, the problem of the length of the
disk device arises. That is to say, the dimension D of the device
is increased as a result.
[0009] A device as disclosed in JP-A-63-200354 for example has been
proposed to solve problems such as the above. FIGS. 106 and 107 are
schematic cross sectional views of a lateral cross section of main
components. FIG. 108 is a schematic cross sectional view of an
upper cross section of main components.
[0010] In FIGS. 106, 107 and 108, reference numeral 19 denotes a
magazine loading an interchangeable disk, 21 is a disk motor, 22 is
a disk clamp hub disposed on a shaft of the disk motor, and 23 is a
disk clamp.
[0011] 26 is a disk roller which transfers a disk 25, which is
ejected by a drive lever 24 driven by a drive means (not shown), to
a disk drive section and 27 is a subordinate roller which operates
in an opposed direction to the disk roller 26.
[0012] 32 is a pair of inclined plate cams which engage with a
plurality of trays 31 in the magazine 19 and which operate so that
when a disk displaces in a lateral direction, a gap E at least
having a thickness greater than or equal to the thickness of the
disk is provided with respect to the disk drive section 20 in an
axial rotation direction of a disk 25 which is selected by the
magazine displacement means (not shown).
[0013] The disk rotation drive means 20 is comprised of a disk
motor 21, a disk clamp hub 22, a disk clamp 23, a drive lever 24, a
disk 25, a disk roller 26, a subordinate roller 27, and an inclined
plate cam 32.
[0014] Next, the operation of the conventional disk device will be
described below.
[0015] When any one of a plurality of disks 25 which are loaded in
a magazine 19 is selected, the magazine 19 is displaced in a
direction F as shown by the arrow in the figure by a drive means
and positioned at a desired disk position in the magazine 19.
[0016] A drive lever 24 in the magazine 19 is operated, and the
disk 25 slides the disk guide 35 in the magazine 19. The leading
edge of the disk 25 is gripped between the disk roller 26 of the
disk drive section 20 and the subordinate roller 27. After the disk
is conveyed to a position of the disk clamp 23 and the disk clamp
hub 22 which is provided on a shaft of the disk motor 21, the clamp
position of the disk 25 is confirmed by a disk detection means (not
shown). The roller 27 on the subordinate side of the disk clamp 23
and the disk roller 26 is displaced in the direction of the disk
clamp hub 22 by the drive means and the disk 25 is clamped.
[0017] At the same time as the subordinate roller 27 displaces in
the direction of the disk clamp hub 22, the pair of inclined plate
cams 32 provided on the disk drive section 20 are displaced toward
the magazine 19 by the drive means. A suitable gap E as shown in
FIG. 107 is formed by the inclination of the tray 31.
[0018] Since a conventional disk device is comprised as shown
above, the problem has arisen that disks can not be selectively
inserted or retracted as required one at a time since a magazine
case is required and that the size of the device is increased.
[0019] As a conventional disk device uses a conveyable magazine
case, a complicated mechanism is required in order to separate each
of the loading shelves loading disks in the disk device. When disks
are played and a gap is formed between a played disk and an opposed
disk, the gap may be enlarged as only one end can be opened. As a
result, the problem has arisen that it becomes necessary to provide
a space in the device which as a result, enlarges the size of the
disk device to that degree.
[0020] As a result of the conventional disk device using a
conveyable magazine case, it is extremely difficult to divide each
loading shelf loading disks in the disk device by inclining each
loading shelf.
[0021] In order to maintain a space in the disk device, the problem
has arisen that the size of the device is increased.
[0022] Since the conventional disk device is constructed to retain
a disk outer periphery when retaining a disk in the device, the
problem arises that the number of components is increased when
retaining sections must be provided which corresponds to disks with
a plurality of differing diameters.
[0023] It has been proposed to solve the above problem by the
provision of a retaining section with the functions of retaining a
plurality of disks of differing diameters with a single retaining
section. However when such a device is constructed in this way,
since a retaining section which retains small diameter disk must be
provided, the problem arises that the retaining section for small
diameter disks abuts and damages the face of large diameter disks
when such disks are also loaded.
SUMMARY OF THE INVENTION
[0024] The present invention is proposed to solve the above
problems and has the object of providing a disk device with reduced
dimensions which is adapted to store a plurality of disks without
using a detachable magazine and to perform respective operations,
that is to say, to selectively insert, eject and play each
disk.
[0025] The present invention has the further object of providing a
disk device with reduced space by the disposition of a disk loading
position and disk playing position on the same rotational axis with
respect to a disk insertion/ejection direction.
[0026] The present invention has the further object of providing a
disk device which prevents damage to the face of a disk by
supporting a section of the disk when a disk is inserted or ejected
by a plurality of support sections.
[0027] A disk device of the present invention is provided with a
plurality of rotatable disk support means which form a support
section which supports a section of a peripheral section of a disk
and a support control means which rotates said plurality of disk
support means based on an operation of said disk and which controls
a support state of said support section with respect to a
peripheral section of a disk. In such a manner, when a disk is
supported, since it is possible to support the disk by supporting a
peripheral section of the disk, it is possible to prevent damage to
the disk surface and to improve the performance of the device.
[0028] The disk device of the present invention is characterized in
that the support control means displaces the support means after
the completion of a disk position determination operation to a
fixed position in the device. With such an arrangement, it is
possible to stabilize disk support operations by performing disk
support operations at a suitable position, to prevent damage to the
disk surface due to disks falling in the device and to improve the
performance of the device.
[0029] The disk device of the present invention is characterized in
that when the support control means performs a disk playing
operation, the support means is displaced in a direction of a
rotational axis of the disk so that a disk determined to a fixed
position is set to a playing operation position. In such a manner,
it is possible to support the disk and to minimize the displacment
distance for the disk to a playing operation. Thus the processing
time for the device may be reduced.
[0030] With the above operations, since it is possible to retain a
disk with a simple mechanism irrespective of the diameter of the
disk, the number of components may be reduced. Furthermore since
the retaining operation of the disk is performed in proximity to an
inner diameter of the disk, it is possible to downscale the
device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0139] In order to describe the invention in greater detail, the
preferred embodiments will be outlined below with reference to the
accompanying figures.
Embodiment 1
[0140] FIG. 1 is a schematic view of the inner components of a disk
device according to a first embodiment of the present invention.
The respective mechanisms of the disk device can be broadly divided
into five sections.
[0141] FIG. 1 shows a disk insertion/ejection mechanism 100 which
performs insertion and ejection of disks and which is disposed in
proximity of a disk insertion mouth. FIG. 2 shows a disk position
determination mechanism 200 which discriminates the diameter of a
disk and which fixes the disk to a retained position in the device.
FIG. 3 shows a disk support mechanism 300 which supports a disk
which has been retained in a determined position by the disk
position determination mechanism. FIG. 4 shows a disk playing
mechanism 400 which performs playing of disks and which is
supported by the disk support mechanism. FIG. 5 shows a disk
loading mechanism which regulates the height of each disk which has
been or will be retained and loaded in the device.
[0142] The basic operation of the disk device will be explained
below.
[0143] First when the insertion of a disk into the disk device is
detected, operations to convey a disk into the device are initiated
by the disk insertion/ejection mechanism.
[0144] A section of the disk position determination mechanism 200
abuts with a peripheral edge of the disk and the diameter of the
disk is discriminated. Based on the result of this determination,
positional determination of the disk is performed by the disk
position determination mechanism and the disk is set in a fixed
position so that the disk rotation shaft is in a fixed position,
that is to say, a playing position.
[0145] After the disk position determination mechanism has
determined the position of the disk, the disk supporting mechanism
supports the disk so that the disk maintains a set fixed position
and maintains the height of the disk in the device.
[0146] Then when the disk supporting mechanism supports the disk,
the disk playing mechanism is displaced to a playing position of
the disk to be played by a rotational action. As a result, the
playing operation of the disk is performed.
[0147] During the playing operation of the disk, the disk
insertion/ejection mechanism displaces toward the disk insertion
mouth so as not to impede the playing of the disk.
[0148] On receipt of a disk ejection command, the sequence of
operations described above is performed in reverse. That is to say,
the playing of the disk by the disk playing mechanism is suspended.
The disk support mechanism supports the disk and after the disk is
supported, the disk playing mechanism rotates in a direction which
is opposite to that during disk play and transfers the disk to a
loaded position. Then a disk ejection operation is performed to
eject the disk out of the device by the disk insertion/ejection
mechanism and an entire sequence of operations is completed.
[0149] Although the description of the operations above only
described the sequence of playing a disk inserted into the device
and ejecting the disk out of the device, a sequence of operations
will be explained with respect to performing switching operations
of a plurality of disks loaded in a device from a disk during a
playing operation to a disk which a user desired to play.
[0150] First, the playing operation of a first disk is terminated.
The disk support mechanism supports the first disk and thereafter
the disk playing mechanism rotates in a direction opposite to that
during playing operations for the first disk and displaces to a
loading position. At that time, a second disk is loaded in the disk
loading mechanism.
[0151] Then after the disk insertion/ejection mechanism is
retracted towards a disk insertion mouth to a fixed position which
is not opposite the surface of the first disk, a section of the
disk loading mechanism extends from a lower section of the device
while loosely fixing the hole of the first disk to an upper section
of the device. After completion of the connection operation with
another section of the disk loading mechanism, support of the first
disk by the disk support mechanism is released. Thus the first disk
is loaded only by the disk loading mechanism.
[0152] When support of the first disk is released, the drive means
initiates a driving operation. The disk loading mechanism which
loosely fixes the disk is rotated and the height of a second disk
is switched, that is to say, the desired disk, the second disk, is
placed in a playing height. At the same time, the height of the
first disk is switched based on the rotation of the disk loading
mechanism so that the disk is loaded at a height that differs from
a playing position.
[0153] After the second disk support operation wherein the disk
support mechanism operates to support the second disk, the disk
loading mechanism rotates in a direction opposite to that when the
first disk is loaded. The mechanism separates from the hole of the
second disk and retracts to a lower section of the device. The
second disk at this time is supported only by the disk support
mechanism and is set in a playing position.
[0154] After the disk insertion/ejection mechanism displaces to a
fixed position in the device, the disk playing mechanism displaces
towards the second disk in order to play the second disk. After
reaching a fixed playing position, the support of the disk support
mechanism is released, and after release, the second disk is
played.
[0155] The basic operation of the disk device has the above
functions. Firstly the main components of the overall disk device
will be described below. Thereafter the five mechanisms referred to
above will be described in detail.
[0156] 1. Main Components of Overall Disk Device
[0157] FIG. 1 is a schematic view of an overall disk device
according to a first embodiment of the present invention. In FIG. 1
and FIG. 2, reference numeral 50 denotes a housing of a disk
device, 51 is a disk insertion mouth allowing insertion or ejection
of disks into the housing 50 that is to say, into the disk
device.
[0158] 1000 is a disk insertion/ejection mechanism which allows
insertion or ejection of disks into the housing 50. The disk
insertion/ejection mechanism 1000 comprises a drive roller 101
which inserts or ejects a disk into the device, a disk biasing
section 102 which disposed at a position facing the drive roller
101, and a roller displacement means 103 which displaces the drive
roller 101 and the disk biasing section 102 in a range from near
the disk insertion mouth 51 into the device. A disk inserted from
the disk insertion mouth 51 is gripped between the drive roller 101
and the disk biasing section 102 and is inserted into the device by
the rotating operation of the drive roller 101.
[0159] 2000 is a disk position determination mechanism which
comprises an abutting pin 201, a position determination section 202
and a link section 203. The abutting section 201 is disposed
adjacent to the center of the disk conveying path. The pin abuts
with a section of the disk peripheral section due to the disk
insertion position with respect to the disk insertion mouth 51 and
the disk diameter of the inserted disk. The position determination
section 202 determines the position of disks of respective
diameters to fixed positions in response to the diameters of the
inserted disks. The link section 203 transmits the displacement of
the abutting pin 201 to the fixed section (discussed below). The
link section 203 of the disk position determination mechanism 2000
displaces to a position determination point for large disks and
fixes the large disk to a fixed position. When a large diameter
disk (for example with a diameter of 12 cm) is inserted and the
large diameter disk abuts with the position determination section
202, the peripheral section of the disk abuts with the abutting pin
201. Thus the abutment of the fixed section (discussed below) which
determines the position of the position determination section 202
is released. The position determination section 202 then passes the
positional determination point for small disks (for example disk
with an 8 cm diameter) from the disk insertion refuge position and
thus displaces further away.
[0160] 3000 is a disk supporting mechanism which supports a section
of a disk surface near a peripheral section which has been inserted
by the disk insertion/ejection mechanism 1000 and determined to a
fixed position by the disk position determination mechanism 2000.
The disk supporting mechanism 3000 comprises three support arms
301, 302, 303. The support arms 301, 302, 303 are normally refuged
to three respective positions proximate to walls in the housing 50.
The support arms are displaced to a proximate position to the disk
and support the disk only when the disk support operations are
performed. At such times, the disk is supported at three support
points by the support arms 301, 302, 303.
[0161] 4000 is a disk playing mechanism for playing disks. The disk
playing mechanism 4000 is adapted to refuge to a position near a
wall of the housing 50 when not performing a playing operation of a
disk (including a preparation for a playing operation) and to
displace to a disk playing position only when performing disk
playing operations.
[0162] The details of the above components will be described below.
However a turntable which is provided at a position at which the
disk is loaded, a drive motor which rotates and drives a disk
mounted on the turntable and a pickup which reads information
recorded on the disk are provided on the disk playing mechanism
4000.
[0163] 5000 is a disk loading mechanism which retains and loads
disks in the device and which regulates the height of a disk by a
rotation operation. The disk loading mechanism 5000 operates when a
second disk is loaded in the device, the disk playing device 4000
suspends the playing of the first disk and the second disk is
played or when a plurality of disks are loaded in the device, a
desired disk is selected from this plurality of disks and played or
when a disk height is switched and a disk is loaded.
[0164] The disk loading mechanism 5000 places the surface of each
disk inserted from the disk insertion/ejection mechanism 1000 into
a roughly parallel orientation and retains and loads disks so that
the center of the axis of rotation of each disk is approximately in
line. In embodiment 1, the device is adapted to load six disks.
[0165] Although the overall structure of the device is described
above, the details of the structure and operation of each mechanism
will be described in detail below.
[0166] 2. Disk Insertion/Ejection Mechanism
[0167] FIG. 2 to FIG. 6 show the disk insertion/ejection mechanism
of the present invention. FIG. (a) is an upper schematic view
showing the components of the device as seen from an upper face of
the device, (b) is a left lateral view of FIG. (a) and shows the
inner components as seen from the left side. FIG. (c) is a right
lateral view of FIG. (a) and shows the inner components as seen
from the right side.
[0168] FIG. 2(d) is an explanatory view of the positional
relationship between a disk inserted into these disks and the drive
roller 101 and disk biasing section 102. This figure corresponds to
FIG. (b), that is to say, to the left lateral view of the
device.
[0169] In FIG. 2(a) to (d), 50 is a housing of the disk device, 51
is a disk insertion mouth through which disks S are inserted or
ejected into or from the disk device, that is to say, into the
housing 50. 101 is a drive roller which displaces a disk into or
out of the disk device. 102 is a disk biasing section composed of
plate metal which is disposed at a position opposite the drive
roller 101 and which grips the disk with the drive roller when the
drive roller 101 drives, that is to say, when the disk is displaced
into the device. 103 is a roller displacement mechanism which
displaces a roller mechanism comprised of the drive roller 101 and
the disk biasing section 102 in the device along a disk conveying
pathway (not shown).
[0170] The operation of the roller displacement mechanism 103 will
be described below.
[0171] The roller displacement mechanism 103 is provided with a
motor 1031 which acts as a drive source which drives the roller
mechanism, which is comprised of a drive roller 101 and a disk
biasing section 102, along a disk conveying path, a worm gear 1032
which is engaged to a rotational shaft of the motor 1031 and forms
a gear on an outer peripheral section, gears 1033-1037 in which the
rotation of the worm gear 1032 is transmitted between each gear,
and a gear 1038 one section of which is engaged with an end of the
drive roller 101 and which is engaged with a gear 1037 when
performing disk insertion/ejection operations. The gear 1038 is
linked to the rotating operation of the gear 1037 and drives the
rotation of the drive roller 101.
[0172] The gears 1035-1037 are axially supported to rotate freely
on a plate 1039. A hole is formed in a section of the center shaft
which rotates the main body of the plate 1039. A projection 1040a
is provided and a motor mounting plate 1040 is provided which
disposes the motor 1031 on the housing 50. The projection 1040a
supports and loosely fixes the gear 1034 and supports and loosely
fixes the hole of the plate 1039.
[0173] The roller displacement mechanism 103 has an elongated hole
1041a, the length of which is formed in an approximately vertical
direction with respect to the direction of disk insertion/ejection.
When the displacement of the drive roller 101 is limited in the
direction-of disk insertion/ejection by the elongated hole 1041a,
the drive roller 101 is displaced in an approximately vertical
direction with respect to the direction of disk insertion/ejection.
That is to say, a base 1041 is provided which displaces in
direction A or direction B. On the base 1041, pins 1041a-1041c are
provided which project towards the housing 50. Elongated holes
50a-50c are formed on a wall of the housing 50 which allow sliding
of the pins 1041a-1041c in a fixed position with respect to the
pins 1041a-1041c. As a result, the roller displacement mechanism
103 displaces in direction C or direction D due to the sliding
action of the pins 1041a-1041c in the elongated holes 50a-50c.
[0174] Guide holes 50d, 50e which defined the sliding respectively
of one end and the other end of the drive roller 101 are formed on
each left and right lateral section of the housing 50 with respect
to the direction of insertion/ejection of the disks in order to
follow the direction of disk insertion from near the disk insertion
mouth 51. The gap with the disk biasing section 102 from one end
near the disk insertion mouth to a fixed position is marked by the
letter X. The guide holes 50d, 50e are inclined so that from the
fixed position, the drive roller 101 can gradually approach the
disk biasing section 102 up to the interior of the device which is
within the displaceable range of the drive roller 101. That is to
say, the inclination is provided so that the gap with the disk
biasing section 102 is smaller than X. In such a way, when a disk
is inserted from the disk insertion mouth 51, the drive roller 101
is disposed on point P and when the disk is played, the drive
roller 101 is displaced towards the disk insertion mouth to point
Q. When the disk loading mechanism 5000 interchanges a disk, the
drive roller 101 is displaced yet further towards the disk
insertion 51 from point Q and disposed at point R.
[0175] A projection 52 is formed in the device on the lateral face
of the housing 50. A gear 1042 which uses the projection 52 as a
rotation shaft is engaged on the projection 52.
[0176] The plate 1039 is engaged with either the gear 1036 or the
gear 1038 by displacement in either direction E or direction F so
as to be linked with the switching lever discussed below. That is
to say, when the plate 1039 displaces is direction E, the gear 1036
and the gear 1042 engage. When the plate 1039 displaces is
direction F, the gear 1037 and the gear 1038 engage.
[0177] 1043 is a rack plate which is disposed to be approximately
parallel with a surface of the left lateral side of the housing 50.
A rack section 1043a which engages with the gear 1042 plate 1043 is
formed on a section of the rack plate 1043. The rack plate 1043
displaces in a direction of disk insertion/ejection by the rotating
action of the gear 1042. That is to say, it displaces in direction
C or direction D. During such displacement, the projection 1043b
formed on a section of the rack plate 1043 abuts with a section of
the base 1041 and the base 1041 also displaces in the same
direction as the displacement of the rack plate 1043. Furthermore
the projection 1043c formed on another section of the rack plate
1043 abuts with a section of the rotating lever (explained below)
and the rotating lever also displaces in the direction G.
[0178] When the rack plate displaces in direction D, the rotation
lever rotates in direction G and the rotation lever is biased in
direction H by a biasing member (not shown). Thus when the rack
plate 1043 displaces in direction C from a situation in which the
rotation lever is biased in direction G, the abutment of the rack
plate 1043 and the projection 1043c is released and the rack plate
1043 is returned in direction H by the biasing of the biasing
member.
[0179] 1044 is a first arm which forms a projection on both ends.
One projection engages slidably with a hole formed on a front
lateral section of the housing 50. The other projection engages
slidably with an elongated hole (not shown) formed on the base
1041. 1045 is a second arm which forms a projection on both ends.
One projection engages slidably with a hole formed on a front
lateral section of the housing 50. The other projection engages
slidably with an elongated hole (not shown) formed on the base
1041. A projection 1044a is formed in an approximately center
section of the first arm 1044 and a hole is formed in an
approximately center section of the second arm 1045. The projection
1044a is adapted to be loosely fixed into the hole of the second
arm 1045.
[0180] 1046 is a biasing means which biases the first arm 1044 in
direction I and which biases the second arm 1045 in direction J.
The biasing means 1046 is provided with a first spring 1046a and a
second spring 1046b. One end of the first spring abuts with the
proximity of the other end of the first arm 1044 and the other end
abuts with the proximity of the other end of the second arm 1045.
One end of the second spring abuts with the proximity of the other
end of the second arm 1045 and the other end abuts with the
proximity of the other end of the first arm 1045. By such an
arrangement, the first arm 1044 and the second arm 1045 are
normally biased in direction C, that is to say, the base 1041 is
biased in direction C.
[0181] Furthermore smooth operation of the roller displacement
mechanism is performed by the provision of the first arm 1044, the
second arm 1045 and the biasing means 1046.
[0182] As shown in FIG. 2, when the biasing force of the biasing
means 1046 is applied to the first and second arms 1044, 1045, the
drive roller 101 as shown in FIG. 1 is disposed at point P, that is
to say, it is disposed at a position which is most proximate to the
disk biasing section 102.
[0183] Point P represents the most proximate position of the drive
roller 101 and the disk biasing section 102. However needless to
say, both components may abut.
[0184] 1047 is a disk incline correction section. When a disk which
is inserted from the disk insertion mouth 51 is not approximately
parallel with the disk conveying path, that is to say, when the
disk is inserted in an inclined state, the incline of the disk is
corrected forcibly by a section of the above component abutting
with a section of the disk so that the disk is conveyed
approximately parallel with the disk conveying path. 1048 is a
plate which guides the movement of the base 1041 in direction C and
direction D. A hole which supports one of the rotational shafts of
the disk incline correction section 1047 is provided in the housing
50. A hole which supports the other of the rotation shafts of the
disk incline correction section 1047 is provided in the plate 1048.
The disk incline correction section 1047 performs rotation
operations using these holes as support points.
[0185] 1049 is a lever which is disposed on the right lateral side
of the housing by the plate 1048. The lever 1049 forms a hole on
the surface opposite the plate 1048. A projection 1048a formed on
the plate 1048 is supported with a play in the hole and the lever
1049 is adapted to rotate and displaces in direction K or direction
L using the projection 1048a as a rotation shaft.
[0186] A cam groove 1049a and a cam groove 1049b are formed on the
lever 1049.
[0187] A projection 1047a which is engaged with the hole formed on
the housing 50, a projection 1047b which is engaged with the hole
formed on the plate 1048, and a projection 1047c which is engaged
with a cam groove 1049a which is formed on the lever 1049 are
provided on the disk incline correction section 1047.
[0188] The operation of a series of disk insertion and ejection
operations will be described referring to FIG. 2 to FIG. 6.
[0189] FIG. 2 shows the drive roller 101 rotating, that is to say,
the device in a disk loading state. FIG. 3 shows the completion of
the disk insertion operation from the operational state shown in
FIG. 2. In order to play the disk, the disk insertion/ejection
mechanism is displaced in direction A, that is to say, the rack
plate 1043 can displace the roller displacement mechanism. That is
to say, the gear 1042 and the gear 1039 are engaged. FIG. 4 shows
the refuging of the operation as shown in FIG. 3, that is to say, a
disk playing state. FIG. 5 and FIG. 6 show the completion of the
refuging operation of the disk insertion/ejection mechanism from
the state as shown in FIG. 4. FIG. 5 shows the member and the
linkage loading state of the disk loading mechanism (discussed
below) which performs height adjustment of the disk and changing of
disks. FIG. 6 shows the rack plate 1043 displacing in direction A
from the state as shown in FIG. 5. Linked to this displacement, the
linked member (to be discussed below) is shown in a rotated
position.
[0190] As shown in FIG. 2, the motor 1031 is started by detection
of disk insertion and drive force is transmitted from the gear 1032
of the motor 1031 through the gear 1036 to the gear 1037. Since the
plate 1039 at this time rotates in a clockwise direction, the gear
1037 and the gear 1038 engage and the gear 1038 rotates due to the
rotations of the gear 1037. Since the engagement of the gear 1042
and the gear 1036 is released at this time in order to displace the
rack plate 1043, the gear 1036 is rotated by the rotations of the
gear 1035.
[0191] When the device is in a mode in which disk insertion
operations are complete and a disk is played, the engagement of the
gear 1037 and the gear 1038 is released at this time and the plate
1039 rotates in an anti-clockwise direction since it is necessary
to refuge the disk insertion/ejection mechanism which interferes
with the disk playing operation. The gear 1042 and the gear 1036
are engaged in order to displace the rack plate 1043. The rotation
of the gear 1037 is continued at this time, however the rotation of
the gear 1038 is suspended in order to release the engagement of
the gear 1037. Since the gear 1042 and the gear 1036 are engaged,
the rack plate 1043 is displaced and it is possible to refuge the
disk insertion/ejection mechanism. FIG. 4 shows disk playing
operation with the disk insertion/ejection mechanism in a refuged
state. As stated above, when a disk is played, the device is
adapted to refuge the disk insertion/ejection mechanism.
Furthermore the device is adapted to operate the components of the
disk loading mechanism to link with the disk insertion/ejection
mechanism shown in the state in FIG. 6 from the state shown in FIG.
5.
[0192] 3. Disk Position Determination Mechanism
[0193] FIG. 7 to FIG. 12 are related to the disk position
determination mechanism. In each of the figures, FIG. (a) shows an
upper view of the components as seen from the upper surface of the
device. (b) is a left side view of (a) showing the inner components
as seen from the left surface. (c) is a rear view of (a) which
shows the inner components as seen from the rear surface. (d) is a
component view showing components determining the position of the
disk position determination mechanism when the position of a large
diameter disk is determined or when a disk is played.
[0194] FIG. 7 to FIG. 10 show the position determination operation
for a large diameter disk. FIG. 11 and FIG. 12 show the position
determination operation for a small diameter disk.
[0195] A switching mechanism 2100 and a shutter mechanism 2200 are
contained in the disk position determination mechanism 2000. The
disk position determination mechanism, the switching mechanism and
the shutter mechanism will be described in order.
[0196] FIG. 7 shows the state of a disk as inserted. The disk
position determination mechanism at this time is shown in a ready
position for disk insertion. FIG. 8 shows an inserted disk in an
abutting state with the position determination section 2006
(discussed below) which is disposed in the insertion ready
position. FIG. 9 shows the position determination section 2006 as
displaced from the position as shown in FIG. 8 towards to a
position determination point. FIG. 10 shows the completion of the
position determination operation to a position determination point
for a large diameter disk after the completion of the operation as
shown in FIG. 9.
[0197] FIG. 11 shows a small diameter disk being conveyed by the
disk insertion/ejection mechanism. FIG. 12 shows the completion of
the position determination operation to a position determination
point for small diameter disks after the completion of the
operation as shown in FIG. 11.
[0198] In FIGS. 7 (a)-(d), reference numeral 2000 denotes a disk
position determination mechanism which accurately determines a disk
playing position depending on the diameter of each disk whether the
disk is a large diameter disk (for example a 12 cm CD) or a small
diameter disk (for example an 8 cm CD). The disk position
determination mechanism 2000 is comprised of the components
below.
[0199] 2001 is a rotatable arm forming an abutting pin 2001a on one
end towards the disk insertion mouth and a hole 2001b to which a
projection formed on the housing 50 is fixed with a play. The arm
2001 is adapted to rotate in direction A about the hole 2001a and
extend by a section of the peripheral section of the inserted disk
abutting with the abutting pin 2001a (refer to FIG. 7(a)). The arm
2001 is normally biased in direction B due to a biasing means (not
shown) such as a spring. That is to say, when the abutment of the
disk with the abutting pin 2001a is released, the arm 2001 is
adapted to return to the position as shown in FIG. 7 (a).
[0200] 2002 is a plate which is linked to the other end of the arm
2001. When the arm 2001 rotates in direction A, the plate displaces
in direction C and when the arm 2001 rotates in direction B, the
plate displaces in direction D. A projection 2002a is provided on
one end of the plate 2002.
[0201] 2003 is a first rotatable lever on one end of which an
abutting section 2003a is formed which abuts in response to the
displaced position of the projection 2002a provided on the plate
2002. On another end of the first rotatable lever 2003 an elongated
hole 2003b is formed. The first lever 2003 rotates about a hole
2003c in which a projection is fixed with a play which is formed on
an approximately central section of the housing. The first lever
2003 rotates in direction E when the plate 2002 displaces in
direction C and rotates in direction F when the plate 2002
displaces in direction D.
[0202] 2004 is a second lever which forms stoppers 2004b, 2004c
which limit the operation of the third lever 2007 to a fixed
position by fixing a projection 2004a a section of which slides in
the elongated hole 2003 formed on the first lever 2003 and by
fixing a projection (discussed below) form on one end of the third
lever 2007 to a fixed position The second lever 2004 is adapted to
link with the first lever 2003 and to displace in the same
direction as the direction of displacement of the first lever
2003.
[0203] 2005 is a base plate one section of which is fixed to the
housing 50. An elongated hole 2005a is formed on the base plate
2005 and allows a projection (to be discussed below) which is
formed on one end of the third plate 2007 to slide therein.
[0204] 2006 is a position determination section which determines
the position of a disk and has projections 2006a, 2006b which
project in an approximately perpendicular direction with respect to
the disk surface towards the disk insertion mouth. The projections
2006a, 2006b are formed to abut with two points of the disk
peripheral section and thus to determine the position of the disk.
The position determination section 2006 varies an amount of
displacement (displacement distance) in direction G in response to
the diameter of the abutting disk (this point will be explained in
detail in the description of the operation of the device).
[0205] 2007 is a third lever on one end of which a projection 2007a
is formed which is slidable in the elongated hole provided in the
base plate 2005a. The other end supports a position determination
section 2006 to rotate freely by the projections 2006a, 2006b at a
position removed from the disk insertion mouth. When the position
determination section 2006 displaces in direction G, the third
lever 2007 also rotates in an anti-clockwise direction, that is to
say, in direction G. The third lever 2007 and other related
components will be described below.
[0206] 2008 is a fourth lever one end of which is formed to rotate
freely on a section of the base plate 2005. An approximately
central section is layered on an approximately central section of
the third lever 2007 to act as a center of rotation. The other end
supports the position determination section 2006 to rotate freely
by the projections 2006a, 2006b at a position removed from the disk
insertion mouth. When the position determination section 2006
displaces in direction G, the fourth lever 2008 rotates in a
clockwise position, that is to say, it displaces in direction G.
Other components and related operations will be described below in
the same way as the fourth lever 2008.
[0207] FIG. 13 to FIG. 15 show the components linked with the disk
position determination. FIG. (a) shows an upper view of the
components as seen from the upper surface of the device. (b) is a
left side view of (a) showing the components as seen from the left
surface. (c) is a rear view of (a) which shows the components as
seen from the rear surface. (d)-(f) are explanatory figures showing
the structure of the components.
[0208] FIG. 13 shows the state of the device after the performance
of disk positional determination by the disk position determination
mechanism 2000 and before setting to a disk playing operation
state. FIG. 14 shows the initiation of the rotation operation of
the fifth lever 2101 (discussed below). FIG. 15 shows the refuged
position of the disk position determination mechanism 2000 further
in a rear direction together with the completion of the rotation
operation of the fifth lever.
[0209] In FIG. 13, 2100 is a position determination refuge
mechanism which is displaced further in direction G and disposed
towards the rear of the housing when the position determination
section 2006, the third lever 2007, and the fourth lever 2008
participate in disk playing operations with a large diameter disk
disposed in a determined position (details of the operation are
described below).
[0210] The position determination refuge mechanism 2100 comprises a
projection 2101a, a fifth lever 2101 and a sixth lever. The
projection 2101a acts as a rotation point and is fixed with a play
in a hole formed in the base plate 2005 and the fifth lever 2101
has a projection 2101b formed at a position which differs from the
projection 2101a. The sixth lever is formed along the housing, and
has a support point 2102a which is provided to act as a rotation
shaft one end being supported on the housing. The sixth lever forms
another end 2102b in an indented shape. A section of the rack plate
1043 is fixed with a play in the indentation 2102b of the sixth
plate 2102. When the rack plate 1043 displaces in direction A, the
sixth lever 2102 is linked and displaces in direction A by rotating
about the projection 2102a.
[0211] 2103 is a seventh lever formed in a curved shape. The
seventh lever 2103 forms a rotation point 2103a which is provided
on an approximately central section, an abutting section 2103b
which abuts with an upper surface of the rack plate 1043 when one
end is in a mode other than disk play mode, and an engaging section
2103c which is fixed into the elongated hole 2102c formed on a
section of the sixth lever 2102. The seventh lever 2103 is biased
by a biasing means (not shown) so that the engagement section 2103c
is normally in a state of abutment with the rack plate 1043. As a
result, the seventh lever 2103 rotates to abut with the housing due
to the biasing force of the biasing means. That is to say, the
engagement means 2103c as shown in FIG. 15 is engaged with the
elongated hole 2102c of the sixth lever 2102. When in such a state,
the position determination section 2006, the third lever 2007, the
fourth lever 2008 are displaced to refuge in the further position
as shown in FIG. 10.
[0212] The operation of the invention will be described below.
[0213] Firstly, as shown in FIG. 13(d), when the rack plate 1043 is
not displacing, the fifth lever 2101 does not rotate due to the
positional relationship between the elongated hole 2012b formed on
the sixth lever 2102 and the projection 2101a formed on the fifth
lever 2101.
[0214] Then as shown in FIG. 14, when the rack plate 1043 begins to
displace, since the sixth lever 2102 which is linked with the rack
plate 1043 rotates in an anti-clockwise direction, the elongated
hole 2012b formed on the sixth plate 2102 also displaces and the
projection 2101a formed on the fifth lever 2101 rotates in an
anti-clockwise direction being linked with this displacement. This
is the result of the third lever 2007 rotating in an anti-clockwise
direction due to the abutment of one end of the fifth lever 2101
and the third lever 2007.
[0215] The rack plate 1043 is further displaced from the position
as shown in FIG. 14 to that as shown in FIG. 15. The sixth lever
2102 which is linked to the rack plate 1043 is further rotated in
an anti-clockwise direction. Based on the displacement of the
elongated hole 2012b formed on the sixth lever 2102, the projection
2101a formed on the fifth lever 2101 is further rotated in an
anti-clockwise direction being linked with this displacement and
reaches an operation completion position. Thus the position
determination section 2006, the third lever 2007 and the fourth
lever 2008 are shown as having reached an innermost position in the
device.
[0216] The shutter mechanism will now be described.
[0217] In FIG. 16, 2200 is a shutter mechanism which closes the
disk insertion mouth so as not to allow the insertion of disks from
the disk insertion mouth when the disk playing mechanism (described
below) is operating. The shutter mechanism 2200 is formed from the
components below.
[0218] 2201 is a plate which is linked to the rotation operation of
the gear (not shown) which engages with the drive motor (not shown)
and which is adapted to displace in direction A or direction B due
to the drive force of the drive motor. Elongated holes 2201a, 2201b
are formed on the plate 2201.
[0219] 2202 is an eighth lever on one end of which projections
2202a and 2202b are respectively formed. An approximately central
section of the projection 2202b acts as a support point. A
projection 2202c is formed which rotates in an anti-clockwise
direction based on the displacement of the plate 2201. The
projection 2202a of the eighth lever 2202 slides in an elongated
hole 2201a in the plate 2201 and the projection 2202c displaces in
direction C. 2203 is a ninth lever. At one end, a hole 2203a which
engages with a projection 2202c is formed and a projection 2203b is
adapted to slide in an elongated hole formed on a section of the
housing (upper plate). On the other end, a projection 2203c is
formed. When the plate 2201 displaces in direction A, the ninth
lever 2203 is linked and rotates in direction D.
[0220] 2204 is a tenth lever on one end of which a groove 2204a is
formed which guides a projection 2203c of the ninth lever 2203 to
slide freely and on the other end of which a rack section 2204b is
formed. The tenth lever 2204 is adapted to be linked to the
displacement of the ninth lever 2203. That is to say, when the
ninth lever 2203 displaces in direction D, the tenth lever 2204 is
linked to the displacement and rotates in direction D.
[0221] 2205 is a gear which is engaged with the rack 2204b of the
tenth lever 2204.
[0222] 2206 is a plate which is provided with a rack 2206a formed
on one end, a projection 2206b which is fixed with a play to an
elongated hole formed in the base plate (discussed below) and an
elongated hole 2206c which guides the projection formed on the
shutter 2207 (discussed below) to slide freely. The plate 2206 is
adapted to be linked with the displacement of the tenth lever 2204
in direction D and thus the gear section 2206 rotates in an
anti-clockwise direction. Being linked to this rotation, the plate
2206 displaces in direction B.
[0223] A support mechanism 3000 (discussed below) is provided on
the base plate which abuts with a face of a disk and supports the
disk.
[0224] 2207 is a shutter section which forms at both ends,
elongated holes 2207a, 2207b in an axial direction of a disk which
is inserted at both ends and which forms a projection 2207b which
is fixed with a play to freely slide in an elongated hole 2206c
formed on the plate 2206. The shutter section 2207 is linked to
displace with the displacement of the plate 2206. When the plate
2206 displaces in direction B, the elongated hole 2206c formed on
the plate 2206 is adapted to incline in direction E as shown in
FIG. 16(a). Thus the projection 2207c of the shutter section 2207
displaces in direction E due to the guide of the elongated hole
2206c, that is to say, the shutter section 2207 displaces towards
the lower section of the device and disk insertion from the disk
insertion hole can not be performed.
[0225] The elongated hole 2201a of the plate 2201 is structured as
shown in FIG. 16(a) and is adapted so that the shutter section 2207
and the support mechanism are displaced in an axial direction of
the disk due to the elongated hole 2201a guiding the projection
2202a of the eighth lever 2202.
[0226] The operation of the invention will be described below.
[0227] FIG. 16 to FIG. 18 show the shutter components linked with
the disk position determination. FIG. (a) shows an upper view of
the components as seen from the upper surface of the device. (b) is
a left side view of (a) showing the components as seen from the
left surface. (c) is a right view of (a) which shows the components
as seen from the right side.
[0228] The shutter mechanism 2200 is adapted to prevent double
insertion of disks in order to maintain the operational mechanism
of the device when disks which are loaded in the disk loading
mechanism are changed or disks are played.
[0229] FIG. 16 shows the device in a state in which a disk can be
inserted, that is to say, in a state in which the shutter is not
operating so that there is no cover on the disk conveying path.
From this state, the shutter 2207 and the base plate displace in
linked movement due to the displacement of the plate 2201 in
direction A.
[0230] In FIG. 17, the plate 2201 begins to displace in direction A
and displaces so that the projection 2202a of the eighth lever 2202
is disposed to a lower section of the elongated hole 2201a formed
on the plate 2201. As the shutter 2207 displaces downwardly, that
is to say, covers the disk conveying path, disk insertion is
prevented. When the shutter section 2207 is displaced, the disk
support mechanism is displaced upwardly in linked motion and as
shown in FIG. 17, the disk support mechanism is displaced to an
upper section in the device. As the displacement of the rack plate
2201 continues, as shown in FIG. 18, the disk support mechanism is
adapted to displace downwardly in the device.
[0231] FIG. 19 to FIG. 22 show the components of the drive force
transmission switching mechanism 2300 which transmits and switches
the drive force of the motor 1001 to one of the rack plate 1043 or
the drive roller 101 provided on the disk insertion/ejection
mechanism 1000. FIG. (a) shows an upper view of the components as
seen from the upper surface of the device. (b) is a left side view
of (a) showing the components as seen from the left surface. (c) is
a rear view of (a) which shows the components as seen from the rear
side.
[0232] In FIG. 19 to FIG. 22, 2301 is a lever which is adapted to
rotate about a rotation shaft 2301a. The lever 2301 forms an
abutting section 2301b on one end. Together with the displacement
of the second plate in direction A, since one end of the second
plate and the abutting section 2301b also displace in direction A,
the lever 2301 rotates in an anti-clockwise direction. That is to
say, the stopper formed on the second lever 2004 which fixes the
projection also displaces in direction A due to the displacement of
the projection formed on the third lever 2007 in direction A. Thus
since the second lever 2004 displaces in direction A, the lever
2301 rotates in an anti-clockwise direction.
[0233] A biasing means 2302 which is biased normally in direction B
is attached to the lever 2301. The lever 2301 forms a projection
2301c on the other end.
[0234] 2303 is a side plate which is provided with an elongated
hole 2303 in which the projection 2301c of the lever 2301 slides.
The side plate 2303 displaces in direction C or direction D along
the left side of the housing 50. On a section of the side plate
2303, an engagement section 2303a is formed which engages with the
projection 1039a formed on the plate 1039. The projection 1039a
separates from and releases engagement with the engagement section
2303a when the side plate displaces in direction C. When the
projection 1039a is engaged with the engagement section 2303a, the
plate 1039 rotates in a clockwise direction. Thus the gear 1037 and
the gear 1038 mesh and the drive roller 101 rotates. However when
engagement with the engagement section 2303a is released, the plate
1039 rotates in an anti-clockwise direction, the engagement of the
gear 1037 and the gear 1038 is released, the gear 1036 and the gear
1042 engage and the rack plate 1043 is displaced. That is to say,
the disk insertion/ejection mechanism is displaced.
[0235] 2304 is a cam plate (discussed in detail below) and 2305 is
a plate. An engagement section 2305a is formed on one end of the
plate 2305. One end of the cam plate 2304 abuts with the engagement
section 2305a and the other end abuts with a section of the second
plate 2004. As a result, when the cam plate 2304 displaces in
direction A, the plate 2305 displaces in direction A due to linked
motion. Furthermore the second plate 2004 also displaces in
direction A and displaces the side plate 2303 in direction C
through the lever 2301.
[0236] When the disk position determination mechanism 2000 is not
in operation, that is to say, when a disk is not inserted, it is
sometimes necessary to displace the disk insertion/ejection
mechanism 1000. Thus the cam plate 2304 is adapted to displace in
direction A due to being driven by the fixed drive source.
[0237] Of course, it is needless to say that even during a disk
insertion/ejection operation by the disk insertion/ejection
mechanism 1000, that is to say, when the third lever 2007
displaces, the side plate 2303 may be displaced.
[0238] Next the operation of the drive force transmission switching
mechanism 2300 will be described with reference to FIG. 19 to FIG.
22.
[0239] FIG. 19 shows the drive roller 101 rotating with the
projection 1039a formed on the plate 1039 engaged to the engagement
section 2303a of the side plate 2303. FIG. 20 shows the side plate
2303 displaced in direction C by the displacement of the third
lever 2007 as a result of a disk inserted through the disk
insertion/ejection mechanism 1000. The engagement of the projection
1039a of the plate 1039 with the engagement section 2303a is
released and the plate 1039 rotates in an anti-clockwise direction.
The gear 1037 meshes with the gear 1038 and the rack plate 1043 may
be displaced. In FIG. 21, when the disk position determination
mechanism 2000 does not operate, that is to say, when a disk is not
inserted, the cam plate 2304 is displaced in direction A by being
driven by the fixed drive source when it is required to displace
the disk insertion/ejection mechanism 1000. The engagement of the
projection 1039a of the plate 1039 and the engagement section 2303a
is released and the plate 1039 rotates in an anti-clockwise
direction. The gear 1037 meshes with the gear 1038 and the rack
plate 1043 can be displaced.
[0240] In FIG. 22, the cam plate 2304 is shown as further displaced
in direction A, the engagement section 2305a of the plate 2305
completes the rotation operation of the plate 2305 by riding over
the cam plate 2304.
[0241] 4. Disk Support Mechanism
[0242] FIG. 23 is a view from the upper surface of the main
components of the device. (b) is a left side view of (a) and shows
inner components seen form the left side. (c) is a right side view
of (a) and shows inner components seen form the right side. The
structure and operation of the disk support mechanism 3000 will be
described with reference to FIG. 23.
[0243] 3001 is a gear which rotates due to a drive force from a
motor (discussed below) disposed on a lower section of the disk
playing mechanism 4000. The gear 3001 meshes with a gear 3002 and
this gear 3002 meshes with a gear 3003. That is to say, the
rotating operation of the gear 3001 is linked and the gear 3003 is
adapted to rotate via the gear 3002.
[0244] FIG. 16 has already been described, however a rack section
2201b is formed which meshes with the gear 3003 on the plate 2202.
Projections 2201c, 2201d are formed which are fixed with a play to
be slidable respectively in the two elongated holes formed on the
housing 50.
[0245] 3004 is a base plate which forms an elongated hole in two
positions in one corner of a lateral section on the side of the
housing. Projections 3004a, 3004b are formed which are fixed with a
play to slide respectively in these elongated holes. A projection
3004c is formed which is fixed with a play to slide in the
elongated hole 2201e formed on the plate 2201. The base plate 3004
displaces together with the elongated hole 2201e of the plate 2201
in direction A when the plate 2201 displaces in direction A. The
elongated hole 2201c inclines downwardly as a result, and the base
plate 3004 also is depressed downwardly by the displacement of the
plate 2201 in direction A. This is the result of the device being
adapted to mount a designated disk supported by the support
mechanism on the turntable (discussed below) of the disk playing
mechanism which is disposed in proximity to the base plate 3004 as
a result of the base plate 3004 being displaced downwardly.
[0246] First and second retaining arms 3005, 3006 are provided to
rotate freely at a fixed interval on the base plate 3004.
Respective grooves 3005a, 3006a are formed on the distal sections
of the first and second retaining arms 3005, 3006. A section of the
peripheral section of the disk engages with the grooves 3005a,
3006a and retains the disk.
[0247] An elongated hole 2201f is formed on the plate 2201 which
varies the angle of inclination so as to correspond with the
respective differing operational modes as shown in FIG. 24(d).
[0248] 3007 is a freely rotating first lever on one section of
which a projection is formed which is fixed with a play to slide in
the elongated hole 2201f. The rotation shaft 3007a of this first
lever 3007 is formed to be hollow. One section has respectively
flat sections which are approximately parallel. A projection 3007b
which projects in an approximately vertical direction is formed
with respect to the rotation shaft on one end of the rotation shaft
3007a of the first lever 3007. The projection 3007b is fixed with a
play to slide in the elongated hole 2201f of the plate 2201.
[0249] Since a plurality of angles of inclination are set for the
elongated hole 2201f, the first lever 3007 rotates being linked to
the displacement of the projection 3007b of the first lever 3007 in
response to the angle of inclination of the elongated hole 2201f
together with the displacement of the plate 2201. That is to say,
when the plate 2201 displaces in direction A, the first lever 3007
rotates in a clockwise direction and when it displaces in direction
B, the first lever 3007 rotates in an anti-clockwise direction.
[0250] A rotation shaft 3005b is formed on the first retaining arm
3005 which is housed in the hollow section 3007a of the first lever
3007. A projection 3007c is formed on the other end. One section of
the rotation shaft 3005b forms respectively flat sections which are
approximately parallel. The rotation operation of the first lever
3007 is linked and performs the rotation of the first retaining arm
as the flat sections formed on the rotation shaft 3005b of the
first retaining arm 3005 and the flat section 3007a formed on the
hollow section of the first lever 3007 are engaged. Since the first
retaining arm 3005 and the first lever 3007 have the above
relationship, the first retaining arm is adapted to displace in the
direction of the rotation shaft with respect to the first lever
3007.
[0251] That is to say, the first lever 3007 comprises a section of
the disk position determination mechanism and the disk position
determination mechanism itself does not displace in the axial
direction, or conversely does not displace in a rising direction.
On the other hand, the first retaining arm 3005, and the second
retaining arm 3006 are adapted to displace in the axial
direction.
[0252] 3008 is a second lever on one end of which an elongated hole
3008a is formed which loosely fixes a projection 3005c formed on
said first retaining arm 3005 so that the projection can slide. The
second lever 3008 is formed to rotate about a rotation shaft 3008b.
The second lever 3008 is adapted to rotation in an anti-clockwise
direction being linked to the rotation of the first lever 3007 in a
clockwise direction.
[0253] 3009 is a third lever forming a projection 3009a on one end
and a projection 3009b on another end. The projection 3009a of the
third lever 3009 is fixed loosely to slide in an elongated hole
3008c formed on the second lever 3008 and displaces in direction C
being linked to the displacement of the second lever 3008 in an
anti-clockwise direction.
[0254] 3010 is a fourth lever forming on one end an elongated hole
3010a which loosely fixes a projection 3009b formed on the third
lever 3009 so that the projection 3009b can slide. The fourth lever
3010 can rotate about a rotation shaft 3010b. When the third lever
3009 displaces in the direction C, the fourth lever 3010 is linked
to the displacement and rotates in an anti-clockwise direction.
[0255] 3011 is a fifth lever forming an elongated hole 3011a on one
end. The elongated hole 3011a loosely fixes a projection 3010c
which is formed on the other end of the fourth lever 3010 in a
slidable position.
[0256] 3012 is a third retaining arm forming a groove 3012a which
retains a disk. The front section of the third retaining arm 3012
engages with a peripheral section of the disk. The third retaining
arm 3012 is linked to the displacement of the fifth lever 3011 in
direction D and rotates in an anti-clockwise direction.
[0257] 4000 is a disk playing mechanism which plays a disk. Since
the optical pickup and the turntable provided in order to perform
playing of the disk will be described in detail below further
description will be omitted.
[0258] The disk playing mechanism 4000 is adapted to rotate in an
anti-clockwise direction about a rotation axis X and to be linked
to the rotation of the gear 3001. That is to say, the respective
displacement of disk support mechanism 3000 and the disk playing
mechanism are adapted to be synchronized.
[0259] Next the operation of the disk support mechanism will be
described with reference to FIG. 25 to FIG. 32. In FIG. 25 and FIG.
26, a disk inserted through the disk insertion/ejection mechanism
is placed in a determined position by the disk position
determination mechanism 2000. The disk support arms 301, 302 and
303 for refuge to a refuge position and the disk playing mechanism
4000 also refuges to a refuge position.
[0260] In FIG. 27, the cam plate 2201 is displaced in direction A
due to a drive force (discussed below) transmitted from the disk
playing mechanism 4000. The disk support mechanism 3000 rotates
approximately parallel to the face of the disk towards the disk and
supports a section of the outer periphery of the disk. In FIG. 28,
the cam plate 2201 is further displaced in direction A and the disk
playing mechanism 4000 rotates in an anti-clockwise direction and
displaces to a disk playing position from the refuge position. At
this point, the rotational axis of the turntable 4101a (discussed
below) and the rotational axis of the disk supported by the disk
support mechanism 3000 are in alignment.
[0261] In FIG. 29, the cam plate 2201 displaces further in
direction A and the disk support mechanism 3000 displaces towards
the turntable 4101a, that is to say, is displaced upwardly. In this
way, inner diameter of the disk engages with the engagement section
(discussed below) formed on the turntable 4101a and the mounting
operation on the turntable 4101a is completed.
[0262] In FIG. 30, the cam plate 2201 displaces further in
direction A and the clamp mechanism 4200 of the disk playing
mechanism 4000 clamps the disk. After clamping, the support arms
301, 302, 303 of the disk support mechanism 3000 displace to a
refuge position, and after displacement to the refuge position, the
lock of the fixed disk playing mechanism is released and is in a
floating state. After completion of the operation of lock release,
the disk playing operation is commenced.
[0263] The contents of the description above were based on the
operation using a large diameter disk (for example a 12 cm disk).
However below the description of the operation with respect to a
small diameter disk (for example a 8 cm disk) will only detail the
points of difference to the large diameter disk operation.
[0264] In contrast to the large diameter disk operation as shown in
FIG. 28 and FIG. 29, the small disk operation is shown in FIG. 31
and FIG. 32. In these figures, the rotation displacement amount of
the support arms 301, 302, 303 is increased in order to support the
outer periphery of the disk.
[0265] 5. Disk Playing Mechanism
[0266] FIG. 33 is a perspective view of component of the device
according to the present invention. The operation and structure of
the disk playing device 4000 will be described with reference to
FIG. 33.
[0267] The disk playing mechanism 4000 is divided into the five
following mechanisms, that is to say, the playing mechanism 4100,
the clamp mechanism 4200, the fixing mechanism 4300, the rotation
mechanism 4400 and the base mechanism 4500.
[0268] Firstly, the playing mechanism 4100 comprises an optical
pickup which reads a signal recorded on the disk and a feed
mechanism for the optical pickup and a mechanism for playing the
disk such as a turntable which mounts the disk. The clamp mechanism
4200 comprises mechanism which clamps the disk when the disk is
mounted on the turntable provided for mounting disks. The fixing
mechanism 4300 is a mechanism which fixes and releases the floating
state of the disk playing mechanism when playing a disk or when the
disk playing mechanism is in a floating state or when a disk is not
played.
[0269] The rotation mechanism 4400 is a mechanism which is
displaced by the rotation action of rotating between a refuge
position which refuges the disk playing mechanism and the playing
position which performs the playing action for disks. The base
mechanism 4500 comprises the motor 4501 which functioning as a
source of motive force which performs fixed operations on the clamp
mechanism 4200, the fixing mechanism 4300 and the rotation
mechanism 4300, the transmission mechanism which transmits the
drive force of the motor 4501 to the clamp mechanism 4200, the
fixing mechanism 4300 and the rotation mechanism 4400 and the
mounting base 4503 which mounted the components of the playing
mechanism 4100, the clamp mechanism 4200, the fixing mechanism 4300
and the rotation mechanism 4400.
[0270] The playing mechanism 4100 comprises a spindle motor 4101
which rotates a disk, the playing base 4102 which supports the
spindle motor 4101, the pickup 4103 which reads information loaded
on the disk and the pickup transfer mechanism 4104 which displaces
the pickup 4103 between the outer and inner peripheral section of
the disk surface.
[0271] A turntable 4101a is mounted which has the function of
mounting a disk on a rotation rotor of the spindle motor 4101. An
engagement section 4101b which engages with the inner diameter of
the disk is formed on the turntable 4101a.
[0272] A projection 4304 is formed on the playing base 4102. In
order to secure the floating state of the projection 4304, a lock
lever 4303 (discussed below) provided on the rotation base 4401
(discussed below) secures the projection 4304.
[0273] On the clamp mechanism 4200, a clamp 4201 which performs
clamping of the disk by pressuring a disk mounted on the turntable
towards the turntable, a clamp cap 4202 which supports an
approximately central section of the clamp 4201 and allows the
clamp 4201 to rotate, a clamp arm 4203 which is mounted on the
clamp cap, and a hole 4203a on a section of the clamp arm 4203 are
formed. A projection 4102a which is formed on a section of the
playing base 4102 is loosely fixed to rotate in the hole 4203a.
Furthermore a displacement mechanism 4204 is formed which displaces
the clamp arm 4203 to a fixed operational position (playing
operation position or refuge position).
[0274] The lock mechanism 4300 is provided with an oil damper 4301
which is disposed between the playing base 4102 and the rotation
base 4401 (discussed below) and a spring 4302 which is disposed
between the playing base 4102 and the rotation base 4401 so that an
outer peripheral section of the oil damper is covered. The playing
base 4102 normally floats on the rotation base 4401 due to the
spring 4302 and the oil damper 4301. Switching from a floating to a
fixed state is performed as stated above.
[0275] The rotation mechanism 4400 is a rotation base 4401 which is
provided with a playing mechanism 4100, a clamp mechanism 4200 and
a fixing mechanism 4300. The rotation base 4401 is adapted to
rotate between a playing position and a refuge position on an shaft
4503 extending from the mounting base 4501 (discussed below).
[0276] The base mechanism 4500 is provided with a base 4501 mounted
on the housing 50. On the mounting base 4501, a motor 4502 and a
drive force transmission mechanism (not shown) of the motor 4502
are provided. A cam plate 4503 is provided which displaces in
direction A due to the drive force transmitted from the drive force
transmission mechanism.
[0277] The operation of the rotation mechanism 4400 and the base
mechanism 4500 will be explained mainly using FIG. 35 to FIG.
44.
[0278] Firstly with reference to FIG. 35 and FIG. 36, the operation
of the base mechanism 4500 will be described. The worm gear 4504,
the large diameter gear and the small diameter gear provided on the
rotation shaft of the motor 4502 mounted on the mounting base 4501
mesh with the large diameter gear of the co-axially integrated gear
4505. The large diameter gear of the gear 4505 and the integrated
small radius gear meshes with the rack section 4503a of the cam
plate 4503 formed on the rack 4503a.
[0279] By such an arrangement, the cam plate 4503 is displaced in
direction A or direction B through the gear 4505 being linked to
the rotation of the motor 4502. Elongated holes 4503b, 4503c are
formed towards the base 4501 of the cam plate 4503. Projections
4506, 4507 which extend from the housing 50 are loosely fixed and
slide in the respective elongated holes 4503b, 4503c. A cam groove
4503d which controls the rotation of the rotation mechanism 4400
and a cam groove 4503e which controls the disk clamping operation
of the clamp mechanism 4200 are formed on the cam plate 4503. A
rack section 4503f is formed at positions on the rack plate 4503
which sandwich the elongated groove 4503c with respect to the rack
section 4503a. By this structure, the rack 4503f meshes with the
gear 3001, the plate 2201 can be displaced and the disk support
mechanism 3000 can be driven.
[0280] A rack plate 4508 is formed in the fixing mechanism 4300 and
sets the playing base 4102 to a fixed or a floating state.
[0281] With reference to FIG. 39 and FIG. 40, a hole 4401a is
provided on the rotation base 4401 and acts as a rotation center
when rotating in either a refuge position or a position which plays
a disk by a rotational operation. A projection 4506 which extends
from the housing 50 to the hole 4401a is loosely fixed and rotates
approximately parallel to the disk surface of the disk which is
played.
[0282] A mounting plate 4402 is disposed on a rear face of the
rotation base 4401 and is provided with a projection 4402a which
engages with the cam groove 4503d of the cam plate 4503. Thus the
cam plate 4503 displaces in direction A as shown in FIG. 41 (disk
playing mechanism refuge position) to FIG. 44 (disk playing
position) and the rotation base 4401 is rotated in response to each
groove position of the cam groove 4503d of the cam plate 4503.
[0283] With reference to FIG. 39, stoppers 5241 (discussed below)
formed on the threaded element 5240 of the disk loading mechanism
5000 on the face of the rotation base 4401 are guided and
determined to a fixed position. A fixing section 4403 which can be
fixed to the stopper 5241 is formed which is fixed to the stopper
5241 during disk playing and released from the stopper 5241 during
other operations.
[0284] The fixing section 4403 has a width which corresponds to the
diameter of the stopper 5241 and only fixes that stopper 5241 to
the position determining section 4403a, which represents a fixed
position. When members other than the stopper 5241 come into play,
refuging sections 4403b, 4403c, 4403d perform refuging operations
so that the position is not determined by the position
determination section 4403a.
[0285] The position of the position determination section 4403a is
set so as to be co-axially disposed with respect to the rotation
shaft of the spindle motor 4101 of the playing mechanism 4100 which
is disposed above the rotation base 4401. When a disk is played,
since the positional relationship of the rotation shaft of the disk
loading mechanism 5000 (discussed below) and the rotated disk
playing mechanism 4000 is not always equal, the disk is mounted on
the turntable and a series of operations is performed until disk
play is accomplished. As a result it is possible to improve the
reliability of the disk device.
[0286] 6. Disk Loading Mechanism
[0287] FIG. 61 is a perspective view of the outer appearance of a
disk loading mechanism. FIG. 62 is an exploded view of the
components of a disk loading mechanism. FIG. 61 (a)-(d) shows the
operation of the disk loading mechanism components. FIG. 62 (a) is
a lateral view of the components, (b) is an upper view showing an
upper face corresponding to each component as shown in (a).
[0288] The schematic components of the disk loading mechanism 5000
will be described with reference to FIG. 61. Details of each
component will be described with reference to FIG. 62.
[0289] In FIG. 61, the disk loading mechanism 5000 is broadly
divided into four component mechanisms. A first mandrel mechanism
5100, a second mandrel mechanism 5200, a third mandrel mechanism
5300, and a disk supporting mechanism 5400 are provided. The first
mandrel mechanism 5100 is disposed to rotate due to the rotational
force of a drive source (discussed below) and a section is fixed to
a roof section of the housing 50. The second mandrel mechanism 5200
which is disposed to rotate due to the rotational force of a drive
source (discussed below) and a section is fixed to a bottom section
of the housing 50. The third mandrel mechanism 5300 which is
disposed to displace the direction of a rotation shaft in response
to the rotations of the second mandrel mechanism 5200 and is
disposed so that the second mandrel mechanism 5200 is engaged to an
inner section. The donut-shaped disk supporting mechanism 5400 is
fixed with a play to the first mandrel mechanism 5100 and the third
mandrel mechanism 5300 and forms a projection on a peripheral
section which is engagable with the grooves formed on the third
mandrel mechanism 5300 and the first mandrel mechanism 5100.
[0290] The disk support mechanism 5400 displaces towards the
rotational shaft along the groove on the third mandrel mechanism
5300 and the groove of the first mandrel mechanism 5100 in response
to the rotational action of the third mandrel mechanism 5300 and
the first mandrel mechanism 5100. That is to say, the disk support
mechanism 5400 is adapted to displace freely in a vertical
direction with respect to the device and to have the function of
supporting disks.
[0291] One end of the first mandrel mechanism 5100 is mounted on
the gear 5111 through a roof plate of the housing 50. A rotatable
first guide member 5110 forms three grooves 5112-5114 on an outer
periphery. A ring-shaped biased spring member 5120 is disposed on
the inner section 5115 of the first guide member 5110 and biases
the first guide member 5110 in direction A. The three grooves
5112-5114 open at positions which correspond to the other end of
the first guide section 5110. This mouth corresponds with an mouth
of the groove formed on the second guide section (discussed
below).
[0292] A hollow first holder 5130 is provided to guide the first
guide member 5110 to an inner peripheral section 5131. The first
guide member 5110 is maintained on the housing 50 by fixation of a
section of the first guide member 5110 to a roof section of the
housing 50. Three slits 5132-5134 are formed at equal intervals
along the axial direction on the first holder 5130. The opening
face of these slits 5132-5134 has openings 5132a-5134a.
[0293] Three indentations 5135-5137 are formed at equal intervals
on the outer periphery of the opening face on the first holder
5130. Three indentations 5115-5117 are formed at equal intervals on
the outer periphery of the other end face of the first guide
section 5110.
[0294] The second mandrel section 5200 comprises a second holder
5210, a shaft 5220, a second guide member 5230 and a threaded
member 5240. The second holder 5210 is formed in a hollow shape and
one end abuts with the bottom face of the housing 50. The shaft
5220 is loaded in the second holder 5120, one end abuts with the
bottom face of the housing 50 and functions as a rotating shaft for
the second guide 5230 (discussed below). The second guide member
5230 loosely fixes the shaft 5220 as a rotation shaft and forms
three grooves 5321-5233 in an outer peripheral section. The
threaded member 5240 prevents separation of the second guide 5230
from the other end of the shaft 5220 after the second guide member
5230 is fixed loosely to the shaft 5220. Although being secured by
the threaded member to the second guide 5230 can rotate the shaft
5220 as a rotation shaft. Furthermore a stopper 5241 is formed on
the threaded member 5240 on the opposite side to that fixed by the
spring. The stopper 5241 fixes the stopper of the disk playing
mechanism which is rotated to a playing position.
[0295] The second guide member 5230 has a gear 5234 on and end face
near the bottom of the housing 50. The gear 5234 is linked to the
transmission mechanism of the roller displacement mechanism 103
(not shown). Six slits 5211-5216 are formed at equal intervals
along the axial direction on the second holder 5210.
[0296] The third mandrel mechanism 5300 comprises the third holder
5301 which is formed hollow and has three projections 5302-5304
formed in equal intervals on an inner peripheral section. Three
guide sections 5305-5307 are formed at equal intervals along the
axial direction of the outer peripheral section and three slits
5308-5310 are formed at equal intervals along the axial direction.
The third holder 5301 is arranged so that the slits 5213-5216 of
the second holder 5210 guide the guide sections 5305-5307 of the
third holder 5301 and displaces the third holder 5301 in a rotation
shaft direction.
[0297] The third holder 5301 forms three projections 5311-5313 at
equal intervals on an end face towards the roof of the housing 50.
When the third holder 5301 displaces in the rotation shaft
direction, the projections 5311-5313 respectively engage with the
indentations 5135-5137 of the first holder 5130. Notched claws
5314-5316 are formed on a section of the outer peripheral face. The
projections 5302-5304 formed on the inner peripheral section engage
slidably with grooves 5231-5233 of the second guide section 5230,
are linked with the rotation of the second guide and can displace
in the direction of the rotational axis of the third holder
5301.
[0298] A third guide 5330 is provided forming spiral shaped grooves
5332-5234 and a concentric groove 5331 on an outer peripheral face
and is fixed with a play into the third holder 5301. The end face
of the spiral shaped grooves 5332-5334 of the third guide 5330 near
to the roof of the housing are open and this open face is linked to
the open face of the spiral shaped grooves 5112-5114 of the first
guide 5110 when the third mandrel mechanism 5300 and the first
mandrel mechanism 5100 are linked. The third mandrel mechanism 5300
is formed hollow and the second guide 5230 is fixed therein with a
play. The third mandrel mechanism is adapted to displace in the
direction of a rotation shaft in response to the rotations of the
second guide 5230.
[0299] A section of the claw 5313-5316 formed on the third holder
5301 projects inwardly. The distal end of the claw abuts with the
concentrically shaped groove 5331 formed on the third guide 5330,
that is to say, it is fixed. Due to such an arrangement, the third
holder 5301 rotates freely so that the third guide 5330 does not
separate from the third holder 5301. Three projections are formed
at equal intervals on the third holder 5330 which project towards
the roof face on the end face towards the roof of the housing
50.
[0300] When the third guide 5330 displaces in a direction of a
rotational shaft together with the third holder based on the
rotations of the second guide 5230 and displaces towards the roof
of the housing, the projections 5335-5337 formed on the third guide
engage and are linked with the indentations 5135-5137 of the first
guide 5110. When the third guide 5330 and the first guide 5110 are
linked, the rotation of the gear 5234 formed on the second guide
5230 is fixed and the gear 5111 engaged with the first guide 5110
is rotated. Thus the first guide 5110 and the third guide 5330
become integrated and a rotation action is performed on the
integrated basis. In this case, no displacement occurs in the
direction of the rotational axis.
[0301] 5400 is a support mechanism. On the surface facing the disk,
the support mechanism 5400 comprises a first support section 5411
of the flat section which abuts with and supports a section of the
inner periphery of the disk. The proximity of the inner periphery
is somewhat thickened and comprises a section support section 5412.
A first spacer 5410 is provided with which the inner diameter of
the of the disk is engaged on the second support section 5412. The
first spacer 5410 forms three projections 5413-5415 at equal
distances on an inner section. The projections 5413-5415 are
adapted to slidably engage with the grooves 5112-5114 of the first
guide member 5110 and with the grooves 5332-5334 of the third guide
member. The first spacer 5410 is adapted to displace based on the
rotation of the first guide member 5110 and the third guide member
towards the rotation shaft so that the flat section is
approximately perpendicular to the rotation shaft.
[0302] A first plate spring 5420 is fixed to the opposite face of
the first support section 5411 which abuts with and supports the
disk. The first plate spring 5420 has a larger diameter than the
first spacer 5410. A peripheral section of the first plate spring
5420 extend towards the rotation shaft and in the present
embodiment four extend downwardly at equal intervals. In the
present embodiment of the present invention, four projections
project at equal intervals downwardly in the device. These
projections 5421-5424 are biased towards a lower section of the
device.
[0303] In FIG. 62, only a first spacer 5410 and a first plate
spring 5420 are given as examples of a spacer and a plate spring.
However this embodiment of the present device is adapted to load
six disks with respective spacers and springs provided for each
disk. (The structure of the other spacers and other plate springs
is the same as that of the first spacer 5410 and a first plate
spring 5420. The order of first spacer and spring to sixth spacer
and spring is provided from the upper section of the device to the
lower section of the device.) That is to say, these components are
disposed from the upper section to the lower section of the device
in the order given below.

{circle over (2)} Plate spring member, {circle over (3)} First
spacer, {circle over (4)} First plate spring member, {circle over

[0305] On the support mechanism 5400, a plate spring (not shown in
the figure, but the same as the first plate spring 5420) is
provided which is disposed on the upper step of the first spacer
5410 which biases the disk downwardly by abutting. An upper biasing
member 5430 is provided which grips the disk with the first support
section 5411 of the first spacer 5410 and the plate spring. The
upper biasing member 5430 is provided with an approximately central
hole in the same way as the first plate spring 5420 and the first
spacer 5410. Three projections 5432-5434 are provided at equal
intervals in the inner peripheral section of the approximately
central hole. The upper biasing member 5430 is adapted in the same
way as the first spacer 5410 so that the three projections
5432-5434 are disposed to slidably engage with the grooves
5332-5334 of the third guide member and the grooves 5112-5114 of
the first guide member 5110. The upper biasing section 5430 is
adapted to displace towards a rotation shaft based on the
rotational operation of the first guide member 5430 and the third
guide member.
[0306] When the spacer supports a disk, since the plate spring
immediately above the spacer biases the disk towards the spacer
(for example, when a disk is loaded in the third spacer, the second
plate spring immediately above biases the disk onto the third
spacer), the disk is more firmly supported (retained).
[0307] The projections 5421-5424 of the first plate spring 5420 are
all adapted to extend in the same direction, that is to say as
shown in FIG. 62, from a right hand direction to a left hand
direction.
[0308] Using FIG. 63-FIG. 97, the operation of the disk loading
mechanism will be described. Firstly, the principle of varying the
height of the disk will be described based on FIG. 96 and FIG. 97.
In the figures, a groove formed on a first mandrel mechanism 5100
and a third mandrel mechanism 5300 will be described. These figures
are development elevations open along a rotation shaft. FIG. 96
shows a separated state of the third guide member 5330 and the
first guide member 5510. FIG. 97 shows a linked state of the third
guide member 5330 and the first guide member 5510. The separated
state of the third guide member 5330 and the first guide member
5510 as shown in FIG. 96 is set to the position of the disk
insertion/ejection operation or the disk playing operation. The
linked state of the third guide member 5330 and the first guide
member 5510 as shown in FIG. 97 is set to the position of varying
the height of a disk which is loaded in the disk loading mechanism.
In FIG. 96, in the first guide member 5510, projections formed on
the first, second and third spacers, and the upper biasing section
are fixed with a play to each groove (.circle-solid. shows the
position of each projection). In the third guide member 5330,
projections formed on the fourth, fifth and sixth spacers are fixed
with a play to each groove. The gaps between each groove is as
shown in the figure. In FIG. 97, the fourth disk R is shown as the
disk to be the object of an operation. Furthermore the projections
5551, 5552 of the fourth spacer which supports the fourth disk R
are shown. By the arrangement above, when the disk supporting
mechanism 3000 supports a disk which is indicated from among the
disks loaded in the disk loading mechanism 5000, a mechanism is
provided to prevent the disk support mechanism 3000 from coming
into contact with linked disks when the disk support mechanism 3000
is interposed between disks adjacent to disk R.
[0309] In the figure, three respective grooves are formed on the
first and third guide members, 5510, 5330. That is to say, on the
first guide member 5510, grooves 5112, 5113, 5114 are formed, and
on the second guide member 5530, grooves 5332, 5333, 5334 are
formed. The three grooves have the same structure and are formed
with a 120 degree phase difference. When the disk loading mechanism
5000 rotates through 120 degrees, this results in either the
operation of the raising of the height of the disk by one step or
the lowering of the height of the disk through one step. As shown
in FIG. 96 and FIG. 97, with respect to the groove of the first
guide member 5510, the right end of the first groove 5512 is fixed
to the left end of the first groove 5512b and the right end of the
first groove 5512b is fixed to the left end of the first groove
5512c to form a single groove. Since the second grooves 5513a-5513c
and the third grooves 5514a-5514c are formed in the same way as the
first groove as described above, further description will be
omitted. Furthermore since the grooves 5332, 5533, 5534 of the
third guide member 5530 are formed in the same way as the first
groove 5512a of the first guide member 5510 above, further
description will be omitted. When the device is set to the state as
shown in FIG. 97 from the state as shown in FIG. 96, that is to
say, after the device is set to a linked state from a state in
which the first guide member 5510 and the third guide member 5330
are separated, the disk R which is the object of the operation is
rotated through a fixed angle in a direction which raises the disk
by a step, (the first and third guide member rotate in an
anti-clockwise direction) and the device is set to the position as
shown in FIG. 97. The projections 5302, 5303, 5304 of the third
holder 5301 in the grooves 5231, 5232, 5233 of the second guide
member 5230 have the function of retaining the third guide member
5330 in a rotatable state. Thus the device shifts from the state as
shown in FIG. 96 to the state as shown in FIG. 97, due to the
second guide member 5230 rotating (the position as shown in FIG. 96
shows the second guide member 5230 completely fixed with a play to
the inner section of the third guide member 5330).
[0310] As described above, when the first guide member 5110 and the
third guide member 5330 are separated, the position at which the
projection formed on the spacer is loosely fixed is as shown in
FIG. 96. On the other hand, when the disk which is to be the object
of an operation is supported and refuged by the disk support
mechanism 3000, the position of fixation of the projection is as
shown in FIG. 97.
[0311] That is to say, when the first guide member 5110 and the
third guide member 5330 are linked and the disk to be the object of
an operation becomes selectable, firstly the device displaces to
the position as shown in FIG. 97. Thereafter the disk to be the
object of an operation is set to the position of the disk R. As a
result of such an operation, the plate spring member mounted on the
spacer on which a disk is loaded which is one step higher than the
disk R to be the object of an operation is adapted to bias the disk
R to be the object of an operation downwardly. Thus the disk R to
be the object of an operation is firmly biased to prevent a shaking
movement. Thus the supporting action of the disk supporting
mechanism 3000 with respect to the disk R to be the object of an
operation is facilitated.
[0312] On the other hand, when the first guide member 5110 and the
third guide member 5330 are separated, firstly as shown in FIG. 96,
the disk which is disposed one step higher than the disk R which is
the object of the operation when the above components are linked is
displaced to the groove of the first guide member 5110 from the
third guide member 5330.
[0313] Next a sequence of operations of the disk loading mechanism
5000 will be described. In the FIGS., (b) is a development
elevation showing the positional relationship between the first
member 5110, the second guide member 5230 and the third guide
member 5330 during the operation as shown in (a). That is to say,
it shows the positional relationship of the groove with the
projection of each spacer.
[0314] Firstly as shown in FIG. 67, the disk R1 is supported by the
disk support mechanism 3000 (not shown in the present figure). The
first guide member 5110 and the third guide member 5330 become
linked thereafter in FIG. 70 due to the operation as shown in FIG.
68 and FIG. 69.
[0315] The operation of each mandrel mechanism from that as shown
in FIG. 67 to that as shown in FIG. 70 will be described using FIG.
65 and FIG. 66.
[0316] In the figures, the projection 1043c of the plate 1043 abuts
with a projection 6001a formed on one end of the lever 6001 due to
the displacement of the plate 1043 in direction A. Together with
the displacement of the plate 1043, the lever 6001 rotates in
direction C. A gear section 6001b is formed on the curved section
of the lever 6001. Together with the displacement of the lever in
direction B, the gear link which meshes with the gear section 6001b
is rotated. Such rotations are transmitted to the gear section 5234
formed on a lower end of the second guide member 5234 and thus the
gear section 5234 is rotated. That is to say, the second guide
member 5230 is rotated and the third mandrel mechanism 5300 is
displaced in the direction of the rotation shaft (in the present
embodiment, the third mandrel mechanism 5300 displaces towards an
upper section of the device). On the other hand, when the operation
of returning the plate 1043 in direction B is performed, the linked
lever 6001 is rotated in direction D and the third mandrel
mechanism 5300 is displaced in the direction of the rotation shaft
(in the present embodiment, the third mandrel mechanism 5300
displaces towards an lower section of the device).
[0317] By such an operation, the third mandrel mechanism 5300
slowly rises to a proximate position with the first mandrel
mechanism 5100 due to the rotational operation of the second guide
member as shown in FIG. 68 and FIG. 69.
[0318] As shown in FIG. 66, the plate 1043 reaches a position
completing the displacement operation and the first mandrel
mechanism 5100 and the third mandrel mechanism 5300 are linked as
shown in FIG. 70. The indentations 5135, 5136, 5137 of the first
holder 5130 are engaged with the projections 5311, 5312, 5313 of
the third holder 5301. The indentations 5115, 5116, 5117 of the
first guide member 5110 are engaged with the projections 5335,
5336, 5337 of the third guide member 5330. The respective openings
of the grooves 5112, 5112, 5113 of the first guide member 5110 and
the grooves 5332, 5333, 5334 of the third guide member 5330 are
aligned, that is to say, so that three linked grooves are formed.
Furthermore the respective openings of the slits 5132, 5133, 5134
of the first guide member 5110 and the slits 5308, 5309, 5310 of
the third holder 5301 are aligned so that three linked slits are
formed.
[0319] The operation of varying the height of a section of a disk
is performed as shown in FIG. 70 and FIG. 71. The operation of
varying the height of a disk will be described with reference to
FIG. 63. In FIG. 71, the rear side of the roof section of the
housing 50 is shown. In the figure, the drive force of a motor 6003
which provides worm gear 6003a on a rotation shaft is transmitted
through a gear link 6004 to rotate a gear 5111 with which the gear
link 6004 meshes. In this way, the first guide member 5110 which is
integrated with the gear 5111 is adapted to rotate. The upper
biasing section 5430 and the first to sixth spacers are adapted to
displace in the direction of a rotation shaft due to the rotating
operation of the first guide member 5110. In the FIG. 70, a space
D1 is provided between the disk R1 which is the object of the
operation and the disk R2 which is positioned one step above the
disk R1. When the operation as shown in FIG. 71 is performed, the
gap D1 between the disk R1 which is the object of the operation and
the disk R2 which is positioned one step above the disk R1 becomes
smaller and displaces the spacer to the position D2. That is to
say, the narrowing of the gap from D1 to D2 displaces the spacer
which is positioned between the disk R1 and the disk R2 to a
proximate position with respect to the disk R1 and allows the force
of biasing of the plate spring member integrated with the spacer to
operate. Thus the disk R1 is biased in a downward direction in the
device and it is possible to prevent shaking of the disk R.
[0320] The exchange of a disk R1 to be the object of an operation
to a disk R3 which is loaded in a disk loading mechanism 5000 was
described by the above series of operations. However after the
operation in FIG. 71, when the disk R3 is played, an opposite
sequence of operations to that described above is performed. That
is to say, the sequence of operations from FIG. 71 to FIG. 67 is
performed (the selected disk is the disk R1, however this is
changed to R3) and thus the disk is played and the device is in the
position (state) as shown in FIG. 73.
[0321] 7. Description of the Operation of the Entire Device
[0322] FIG. 99 to FIG. 101 describe the operational state of each
component in each operational mode of the entire device. FIG. 99
shows the insertion of a disk from the disk insertion mouth, and
the operation of each component up to playing the disk. FIG. 100
shows the operation of each component from the playing of a disk to
the ejection of the played disk from the insertion mouth. FIG. 101
shows a disk played by the disk playing mechanism 4000 as loaded in
the disk loading mechanism 5000 and a single disk which is retained
by the disk loading mechanism 5000 being exchanged for a disk to be
played. To give an example, the figures show the operational state
of each component when the device shifts from a state in which
there are 4 play disks and 1 loaded disk to a state in which there
are 4 played disks and one loaded disk.
[0323] The numerals on the right side denote names of operated
components and the numerals on the upper step denote the sequence
of transitions in operational modes. Each numeral for each
component name shows figure numerals of components with respect to
the sequence of transitional state of operational modes.

[1123] With the completion of operations up to step 25, the device
is in a ready state for disk insertion to that a first disk may be
loaded in a loading position for the first disk and a sequence of
operations is completed.
[1124] Thus as shown above, since it is not necessary to use an
abutting operation on the recording face of a disk when loading a
disk due to the fact that a disk is loaded using an inner diameter
of the disk, it is possible to reduce damage in particular to the
recorded face of the disk and increase device reliability.
[1125] Furthermore since any type of disk (for example, a 12 cm CD
or a 8 cm CD) may be handled irrespective of the size of the disk
diameter, it is possible to increase user friendliness.
[1126] Since the axial center of the loading position of the disk
and the axial center of the playing position of the disk are
aligned, the axial center does not diverge and an operation to
align the axial center during disk exchange operations or the like
is unnecessary. As a result, it is possible to reduce processing
time.
[1127] Since it is possible to handle any type of disk irrespective
of disk diameter by constituting the disk playing mechanism with a
rotating type of mechanism, user friendliness of the device is
enhanced.
[1128] Even if there is an irregularity in the thickness of the
disk due to the biasing force of the plate spring member as a
result of mounting the plate spring member in the spacer of the
disk loading mechanism, it is possible to reduce shaking and to
improve device performance.
[1129] Even in positions in which a disk is not loaded in the
spacer of the disk loading mechanism, it is possible to reduce
shaking due to the biasing force of the plate spring member as a
result of mounting the plate spring member in the space of the disk
loading mechanism and to improve device reliability.
[1130] The provision of a stopper which is fixed at positions
outside the rotational shaft of the disk playing mechanism allows
the disk to be supported at two positions, namely, the rotation
shaft and the stopper when the disk is played. Thus the performance
of the anti-vibration mechanism provided in the disk playing
mechanism can be improved and it is possible to stabilize the
playing of the disk and improve device performance.
[1131] Since the axial center of the disk playing device and the
axial center of the stopper which stops the disk playing mechanism
during disk playing operations are aligned, it is possible to
minimize the operational distance from the disk loading position to
the disk playing position, to reduce transfer time from the disk
loading position to the disk playing position and to reduce
processing time in the device.
[1132] Since the gap with the spacer which is proximate to the
spacer of the disk which is to be played is greater than the gap
between spacers which are not proximate, it is possible to operate
the disk support mechanism when supporting the disk which is to be
played and it is possible to improve device reliability as a
result.
[1133] Since the disk insertion/ejection mechanism is adapted to be
refuged by the face of the projection during disk exchange, it is
possible to use the spacer normally setting the disk
insertion/ejection mechanism as a section of the spacer required
during disk playing, thus enabling the downsizing of the
device.
[1134] Since the disk insertion/ejection mechanism is adapted to
displace in the direction of disk insertion/ejection, it is
possible to displace the disk insertion/ejection mechanism to near
a fixed disk position when the device is in a ready state for disk
insertion. Thus it is possible to insert a small diameter disk into
the device in a stable manner, that is to say, it is possible to
insert a disk accurately into the device irrespective of the type
of disk diameter and thus to improve the performance of the
device.
[1135] Since respective disks may be freely inserted and ejected
independently one by one, user friendliness is enhanced.
Embodiment 2
[1136] A second embodiment of the disk device of the present
invention will be explained with reference to FIG. 98. In the first
embodiment as discussed above, a gap was provided between
respective grooves formed between the first guide member 5110 and
the third guide member 5330 and the size of this gap is adapted to
differ. However an arrangement of gaps formed at equal intervals as
shown in FIG. 98 may be employed. Thus it is possible to increase
the speed of the switching operation to each mode, that is to say,
it is possible to improve the processing speed of the device.
Embodiment 3
[1137] A third embodiment of the device will be discussed below. In
the first embodiment as discussed above, the displacement of each
component was described in each operational mode on the basis of
FIG. 86 to FIG. 88. The operation of each component set in the
respective modes may be respectively synchronized, that is to say,
that the displacement operations may be linked. Since each
component is synchronized in such an arrangement, it is possible to
increase the speed of the displacement operations, to improve the
reliability of the device and to reduce processing time.
Embodiment 4
[1138] A fourth embodiment of the device will be discussed below.
In the first embodiment as discussed above, the manner in which
components are switched during displacement operations in the
progression of operational modes was not noted. However normally
although the device may be adapted so that switching occurs
gradually during switched operational modes, the same result may be
obtained by switching which occurs collectively.
Embodiment 5
[1139] A fifth embodiment of the device will be discussed below. In
the first embodiment as discussed above, the disk
insertion/ejection mechanism 1000 comprised a disk biasing section
102 which functions as a mechanism to grip the disk and which does
not have a member for rotation with the a drive roller 101 which
drives rotation. However variation of the disk biasing section into
a roller member is also possible and such an arrangement allows the
prevention of damage to the disk surface.
Embodiment 6
[1140] A sixth embodiment of the device will be discussed below. In
the first embodiment as discussed above, when a disk is inserted
into the device, it has not been noted in which manner the
operation is performed automatically. However when a disk is
inserted from the disk insertion mouth, the disk insertion/ejection
mechanism 1000 inserts the disk, the disk support mechanism
supports the disk, and the disk is set to be played by the disk
playing mechanism. That is to say, the simple insertion of a disk
results in the setting of the disk to be played. Such an
arrangement increases user friendliness.
Embodiment 7
[1141] A seventh embodiment of the device will be discussed below.
It has been noted that first to third retaining arms are provided
on the disk support mechanism 3000. However a corner of the groove
formed on the first to third retaining arms may be beveled. Such an
arrangement prevents damage to the surface of the disk.
Embodiment 8
[1142] A eighth embodiment of the device will be discussed below.
In the second embodiment as discussed above, since the gap of each
spacer which supports the disk has been placed closely together,
disk movement due to external force or the like are reduced and the
plate spring member provided in each spacer may be omitted. Thus it
is possible to reduce the number of components and to reduce
manufacturing costs.
Embodiment 9
[1143] A ninth embodiment of the device will be discussed below. In
the first embodiment as discussed above, a plate spring member is
mounted in the spacer section. However a pressure spring may be
provided instead of the plate spring member and an equivalent
effect obtained.
Embodiment 10
[1144] A tenth embodiment of the device will be discussed below. In
the first embodiment as discussed above, a retaining member for a
reduced space may be provided by a plate spring member which
retains the inner diameter of the disk on the engagement section of
the spacer. Such an arrangement allows the strengthening of disk
support and reduction in the movement of the disk due to external
forces or the like. Thus the plate spring member may be omitted and
it is possible to downsize the device.
Embodiment 11
[1145] An eleventh embodiment of the device will be discussed
below. In the first embodiment as discussed above, grooves were
formed on the first guide member and third guide member which
loosely fix the projection of the spacer and spacer. A plurality of
three or more of such grooves may be provided to prevent shaking of
the spacer and the improve the reliability of the device.
Industrial Applicability
[1146] As shown above, the disk device of the present invention is
adapted for use as a disk device mounted in a vehicle with a
reduced size and adapted for each operation of loading a plurality
of disks without the provision of a loading magazine, that is to
say, perform the operations of selectively inserting, ejecting and
playing each disk.
