[0001] This application claims the benefit of Japanese Priority
Patent Application JP 2013-169727 filed Aug. 19, 2013, Japanese
Priority Patent Application JP 2013-173891 filed Aug. 23, 2013,
Japanese Priority Patent Application JP 2013-192269 filed Sep. 17,
2013, and Japanese Priority Patent Application JP 2014-011231 filed
Jan. 24, 2014, the entire contents of each of which are
incorporated herein by reference.
BACKGROUND
[0002] The present technology relates to an imaging device which
can perform an imaging operation in cooperation with a display
device.
[0003] There is an apparatus in which one device of devices having
different functions is attachable to and detachable from the other
device. As such an apparatus in which one device is attachable to
and detachable from the other device, for example, there is an
apparatus including an interchangeable lens having a zoom function
and a camera device main body having an imaging function.
[0004] In addition, there is an apparatus in which one device of
devices having different functions is attachable to and detachable
from the other device via an adaptor, and, as an example thereof,
there is an apparatus in which an interchangeable lens is
attachable to and detachable from a camera device main body via an
adaptor (for example, refer to Japanese Unexamined Patent
Application Publication No. 2013-92556).
[0005] Japanese Unexamined Patent Application Publication No.
2013-92556 discloses a method in which the entire adaptor is
rotated about the camera device main body, and an engagement part
is engaged with an engagement part of the camera device main body,
as a method of attaching the adaptor to the camera device main
body.
[0006] Meanwhile, in recent years, along with advance of
communication technique such as a wireless local area network
(LAN), for example, a technique has been developed in which an
image data acquired by an imaging device is displayed on a display
portion (a display) of a display device.
[0007] In such a case where communication is performed between the
display device and the imaging device by using the wireless
communication technique, it is not necessary to provide a structure
for electrical connection between the adaptor and the imaging
device, and thus an attachment mechanism (attachment and detachment
mechanism) of the adaptor to the display device may be a simple
mechanism.
SUMMARY
[0008] Meanwhile, it is necessary for the imaging device which can
perform an imaging operation in cooperation with the display device
to have a device configuration suitable for a cooperative action or
attachment and detachment.
[0009] Therefore, it is desirable to provide a device configuration
suitable for a cooperative action or attachment and detachment.
[0010] According to an embodiment of the present technology, there
is provided an imaging device including a communication part that
transmits an image data to an external display device; an outer
barrel; an imaging element; and first and second coupling parts
that are configured to be coupled to an installation device which
is attachable to and detachable from the display device, in which
the first and second coupling parts are disposed at a rear surface
part of the outer barrel, and in which a storage part that stores a
battery is provided between the first coupling part and the second
coupling part in the rear surface part of the outer barrel. A
device which performs an imaging operation and/or a display
operation in cooperation with an external display device is
implemented using the imaging device having the communication part,
the outer barrel, and the imaging element. In this case, the
battery storage part is provided by effectively using the rear
surface part in which the first and second coupling parts are
provided, that is, the space of the installation surface side with
the installation device. Particularly, since the storage part is
provided between the first and second coupling parts, the storage
part can be provided in a state in which installation of an
installation device is not impeded.
[0011] In addition, preferably, the storage part allows a battery
to be stored from a direction which is substantially perpendicular
to an imaging optical axis. If a battery is stored in a vertical
posture, this does not influence the shape of the outer barrel, and
thus a degree of freedom of design of the imaging device
increases.
[0012] Preferably, the storage part is provided with a battery lid
that closes the storage part storing a battery. The battery lid is
provided, and thus the rear surface part looks good. In addition,
it is possible to prevent a battery from falling.
[0013] Preferably, the storage part is provided with a battery lid
that closes the storage part storing a battery, and the battery lid
is slid downward. It is possible to easily open the battery lid due
to the downward sliding. In addition, due to the downward sliding,
the shape of the battery lid is not exposed to the upper side of
the outer barrel, and thus the external appearance looks good.
[0014] Preferably, the first and second coupling parts are set to
fixed positions so as not to be slid in the rear surface part. The
first and second coupling parts have a structure of not being slid
even if the battery lid is slid. Accordingly, the sliding of the
battery lid does not impede the function of the coupling parts.
[0015] In addition, preferably, the storage part is provided with a
battery lid that closes the storage part storing a battery, and the
battery lid is slid to avoid the first and second coupling parts.
The battery lid has a structure of being slid to avoid the first
and second coupling parts, and thus the sliding of the battery lid
does not impede the function of the coupling parts.
[0016] Preferably, the first and second coupling parts are set to
fixed positions so as not to be slid in the rear surface part.
[0017] In addition, preferably, the storage part is provided with a
battery lid that closes the storage part storing a battery, the
battery lid includes a connection member to the rear surface part
of the outer barrel, the connection member connects an upper side
of the battery lid to the rear surface part, and the battery lid
can be opened upward with the connection member as a fulcrum. The
battery lid is prevented from falling off by the connection
member.
[0018] Preferably, the storage part has a connection terminal to a
battery, which is provided at an upper side in a battery storage
space.
[0019] Preferably, the storage part is formed so that a battery is
horizontally symmetrically stored.
[0020] In addition, preferably, the first and second coupling parts
protrude backward from the rear surface part of the outer barrel.
Accordingly, a shape for engagement is realized.
[0021] Preferably, the first and second coupling parts are disposed
at an outer circumference of the rear surface part of the outer
barrel. The first and second coupling parts are disposed at the
outer circumference, and thus a battery storage space is not
impeded.
[0022] Preferably, the first and second coupling parts include
locking protrusions that protrude outward separately from each
other in a circumferential direction. A state of being engaged with
an installation device is formed by the locking protrusions.
[0023] Preferably, a lock pin that maintains a coupling state is
formed around the first and second coupling parts. A movement in an
unlocked direction and a rotatable movement are restricted by the
lock pin, and thus a coupling state is maintained.
[0024] In addition, preferably, an imaging device main body and the
installation device are relatively rotated via the first and second
coupling parts so as to couple the imaging device main body and the
installation device to each other. Accordingly, coupling between
the imaging device and the installation device can be easily
performed.
[0025] Further, preferably, the imaging device includes an image
taking button, a power button, and a zoom switch; a circumferential
surface part is provided at the outer barrel; the image taking
button is disposed at a left side of the circumferential surface
part; the power button is disposed at an upper side of the
circumferential surface part; and the zoom switch is disposed at
the circumferential surface part. By using the imaging device
including the communication part, the outer barrel, the imaging
element, the image taking button, the power button, and the zoom
switch, it is possible to implement a device suitable for
performing an imaging operation and/or a display operation in
cooperation with an external display device.
[0026] Furthermore, preferably, the imaging device includes an
image taking button, a power button, a zoom switch, and a rolling
prevention part that prevents a device casing from rolling in a
placed state; a circumferential surface part which at least
partially has a curved surface is provided at the outer barrel; the
image taking button is disposed at the circumferential surface
part; the power button is disposed at the circumferential surface
part; the zoom switch is disposed at the circumferential surface
part; and the rolling prevention part is disposed at a lower side
of the circumferential surface part. The shape of the
circumferential surface part having the curved surface is effective
to rolling prevention.
[0027] In addition, preferably, the imaging device includes an
image taking button, and a power button; a circumferential surface
part is provided at the outer barrel; and the image taking button
and the power button are disposed at different positions in a
circumferential direction on the circumferential surface part. By
using the imaging device including the communication part, the
outer barrel, the imaging element, the image taking button, and the
power button, it is possible to implement a device suitable for
performing an imaging operation and/or a display operation in
cooperation with an external display device.
[0028] Preferably, the imaging device further includes a power
button, and the power button is disposed so as not to further
protrude than a surface forming the circumferential surface part of
the outer barrel. The power button does not protrude, which is thus
suitable for preventing the power button from being erroneously
operated.
[0029] Preferably, the imaging device further includes a microphone
that inputs an external sound and is disposed at the
circumferential surface part of the outer barrel. In such a device
in which the outer barrel as a lens casing is a main body, the
circumferential surface part of the outer barrel is most unlikely
to block external sounds, and thus the microphones are disposed at
the circumferential surface part, which is thus suitable for
collecting external sounds.
[0030] Preferably, a tripod hole is disposed at a lower end of the
circumferential surface part of the outer barrel. In a case where
the outer barrel has a formation that outlines the main body of the
imaging device, a tripod hole is formed at the lower end of the
circumferential surface part, and thus balance can be kept well
during attachment of a tripod.
[0031] Preferably, the imaging device further includes a near field
communication part that is disposed at positions other than a rear
surface side of the outer barrel. This is because, if the NEC part
which performs near field communication is disposed at the rear
surface side, when the imaging device is attached to the display
device, polling may occur at all times.
[0032] Preferably, the imaging device further includes a near field
communication part that is disposed at an upper side of the
circumferential surface part of the outer barrel. Accordingly, if
an external device becomes naturally close to the imaging device in
a state of being placed on a desk or the like, wireless
communication can be performed.
[0033] According to the present technology, it is possible to
realize a device configuration suitable for a cooperative action,
an operation, or attachment and detachment in relation to an
imaging device which can perform an imaging operation in
cooperation with an external display device.
[0034] In addition, the effects described in the present
specification are only an example and are not limited, and other
effects may be achieved.

DETAILED DESCRIPTION OF EMBODIMENTS
[0081] Here, embodiments of the present technology will be
described with reference to the accompanying drawings.
[0082] In the following description, directions viewed from a
photographer in an image taking operation using an imaging device
are set to a front and rear direction, a vertical direction, and a
horizontal direction. Therefore, a subject side is a front side,
and the photographer side is a rear side.
[0083] In addition, the front and rear direction, the vertical
direction, and the horizontal direction described below are for
convenience of description, and carrying out the present technology
is not limited to these directions.
[0084] Schematic Configuration of Imaging Unit
[0085] An imaging unit 1 includes an imaging device 2 and an
adaptor 3 (an installation portion or an installation device)
(refer to FIGS. 1 to 3). The adaptor 3 is attachable to and
detachable from a rear surface of the imaging device 2. However,
the imaging unit 1 may have an integrated configuration in which
the adaptor 3 is integrally formed with the imaging device 2 at a
rear end of the imaging device. The imaging device 2 has a
communication function of transmitting and receiving an image data
or the like to and from a display device 4.
[0086] The adaptor 3 is attachable to and detachable from the
display device 4. The display device 4 is, for example, a mobile
phone. However, the display device 4 is not limited to a mobile
phone, and may be other devices having a display function, for
example, a portable terminal, a television system, and the
like.
[0087] In addition, hereinafter, a description will be made of a
case where the imaging device 2 is configured separately from the
adaptor 3, and the adaptor 3 coupled to the imaging device 2 is
attachable to and detachable from the display device 4 which is a
mobile phone.
[0088] Schematic Configuration of Display Device
[0089] The display device 4 includes respective necessary parts
disposed inside and outside an outer casing 5. The outer casing 5
is formed, for example, in a substantially rectangular case shape,
and a display panel 6 is provided on one surface (rear surface).
The display panel 6 is a touch panel, and a predetermined function
is executed by performing a contact operation on each predetermined
position of the display panel 6.
[0090] The display device 4 has a communication function of
transmitting and receiving an image data or the like to and from
the imaging device 2.
[0091] Configuration of Imaging Device
[0092] The imaging device 2 includes an outer barrel 7, a plurality
of lens groups disposed inside the outer barrel 7, and an imaging
element (not illustrated) located on the rear side of the lens
groups (refer to FIGS. 1 to 10). In the imaging device 2, light
incorporated via the lens groups is subject to photoelectric
conversion in the imaging element. Therefore, the imaging device 2
can capture an image data or a video data.
[0093] The outer barrel 7 includes a circumferential surface part
7a which is formed in a substantially cylindrical shape extending
from the front side to the rear side, an overhang part 7b which
overhangs inward from a front end of the circumferential surface
part 7a, and a rear surface part 7c which closes the
circumferential surface part 7a from the rear side.
[0094] Inner barrels 8 and 8 which can be moved in the front and
rear direction are supported inside the outer barrel 7 (refer to
FIGS. 3 to 5). Therefore, the imaging device 2 is turned to an
image taking state (refer to FIG. 4) when the inner barrels 8 and 8
protrude forward with respect to the outer barrel 7, and is turned
to a collapsed state (refer to FIG. 2) when the inner barrels 8 and
8 which have protruded forward are withdrawn backward and are
stored in the outer barrel 7.
[0095] A light passing hole 8a with a substantially rectangular
shape is formed in a front surface part of the inner barrel 8 which
is located on the innermost side (refer to FIG. 4). Lens barriers 9
and 9 are supported on a rear surface side of the front surface
part of the inner barrel 8 which is located on the innermost side,
so as to be freely opened and closed. The lens barriers 9 and 9 are
closed in a collapsed state and are opened in an image taking state
by an opening and closing mechanism (not illustrated). Therefore,
in the collapsed state, the light passing hole 8a of the inner
barrel 8 is closed by the lens barriers 9 and 9 (refer to FIG. 2),
and, in the image taking state, the light passing hole 8a is opened
by the lens barriers 9 and 9 (refer to FIG. 4).
[0096] A plurality of lens groups including an image taking lens 10
(refer to FIG. 4) located on the frontmost side are disposed
separately from each other in the optical axis direction inside the
imaging device 2, and if the light passing hole 8a is opened by the
lens barriers 9 and 9, light is incident to the image taking lens
10 from outside.
[0097] An operation ring 11 is rotatably supported at the front end
of the outer barrel 7 (refer to FIG. 2). When the operation ring 11
is operated, the lens groups which perform manual focusing or
zooming are moved in the optical axis direction.
[0098] The operation ring 11 is provided in a circular shape at the
front end of the outer barrel 7, and thus a user easily performs a
rotation operation of the operation ring 11. If the surface of the
operation ring 11 is formed by a sawtooth-shaped grip part, this is
also suitable for operability improvement of a rotation
operation.
[0099] In addition, the operation ring 11 can change operation
content between a manual focusing operation and a zooming operation
on the basis of control using wireless communication described
later in response to a user's operation from the display device 4.
Therefore, the operation ring 11 may be used as an operation part
of a focusing operation and a zooming operation in accordance with
a user's taste or circumstances.
[0100] First and second coupling parts 12 and 12 which protrude
backward are provided at positions opposite to each other,
180.degree. apart on an outer circumference of the rear surface
part 7c of the outer barrel 7 (refer to FIGS. 3 and 6). Locking
protrusions 12a and 12a which protrude outward separately in a
circumferential direction are respectively provided at the coupling
parts 12 and 12. Accordingly, an engagement structure body is
formed which is engaged with coupling recess parts 18a and 18a and
locking pieces 17a and 17a of the adaptor 3, described later.
[0101] A lock pin 13 is supported movably in the front and rear
direction around the coupling part 12 of the rear surface part 7c,
and the lock pin 13 is biased backward by a spring (not
illustrated).
[0102] An unlock lever 2a is disposed at the rear end of the
circumferential surface part 7a of the outer barrel 7 (refer to
FIG. 10). The unlock lever 2a is operated, and thus the lock pin 13
is drawn into the outer barrel 7.
[0103] A battery lid 2b is disposed at a portion between the
coupling parts 12 and 12 of the rear surface part 7c of the outer
barrel 7 (refer to FIGS. 3 and 6). A battery mounting part 70
(refer to FIGS. 41 and 42) is formed inside the battery lid 2b in
the imaging device 2. The battery lid 2b is opened and closed, and
thus a battery (not illustrated) can be installed in and removed
from the storage part.
[0104] Here, first and second coupling parts 12 and 12 are formed
on the outer circumference in the rear surface part 7c, and thus a
space between the first and second coupling parts 12 and 12 can be
used to dispose the battery lid 2b and the battery mounting part 70
therein. In other words, coupling parts 12 and 12 is formed on the
outer circumference in the rear surface part 7c, and thus do not
impede securing of a battery storage space.
[0105] Microphones 2c and 2c and a power button 2d are disposed
separately from each other in the front and rear direction at the
upper end of the circumferential surface part 7a of the outer
barrel 7 (refer to FIGS. 2, 3 and 7). The microphones 2c and 2c are
parts for inputting external sounds. In the embodiment in which the
outer barrel 7 as a lens casing is a main body, the circumferential
surface part 7a of the outer barrel 7 is most unlikely to block
external sounds among positions where the microphones are easily
disposed. For this reason, the microphones 2c and 2c are disposed
at the circumferential surface part 7a, which is thus suitable for
collecting external sounds. Since the microphones 2c and 2c are
provided at the upper end of the circumferential surface part 7a,
the microphones 2c and 2c are hardly blocked when a user grasps the
outer barrel 7, and thus are suitable to input external sounds.
[0106] In addition, the illustrated microphones 2c and 2c parts are
visually recognized as microphone holes from the outside. The
microphones 2c and 2c are disposed inside the circumferential
surface part 7a, but at least the microphone holes (2c and 2c)
which guide external sounds to the two microphones to which the
external sounds are input are formed at positions which are
horizontally symmetrical to each other on the circumferential
surface part 7a. The horizontally symmetrical positions are
suitable for collecting right and left stereo sounds.
[0107] The power button 2d is disposed so that a surface thereof
does not further protrude than the surface forming the
circumferential surface part 7a. For example, as illustrated in the
figures, the power button is formed so as to be coplanar with the
circumferential surface part 7a. Alternatively, the surface of the
power button 2d may be further depressed than the circumferential
surface part 7a.
[0108] The power button 2d does not further protrude than the
circumferential surface part 7a, which is thus suitable for
preventing the power button 2d from being erroneously operated.
[0109] If the power button 2d is operated, power is supplied or
stops being supplied in the imaging device 2. When power is
supplied, the inner barrels 8 and 8 protrude forward with respect
to the outer barrel 7, thereby setting an image taking state, and
when power stops being supplied, the inner barrels 8 and 8 which
have protruded forward are withdrawn backward and are stored in the
outer barrel 7, thereby setting a collapsed state.
[0110] A tripod hole 2e is formed at the lower end of the
circumferential surface part 7a of the outer barrel 7 (refer to
FIG. 8). The tripod hole 2e is a hole for coupling the imaging
device 2 to a tripod (not illustrated) when an image taking
operation is performed. In a case where the outer barrel 7 has a
formation that outlines the main body of the imaging device 2 as in
the present embodiment, a tripod hole 2e is formed at the lower end
of the circumferential surface part 7a, and thus balance can be
kept well during attachment of a tripod.
[0111] Rolling prevention protrusions 2f and 2f are provided on
right and left sides of the tripod hole 2e at the lower end of the
circumferential surface part 7a of the outer barrel 7 (refer to
FIGS. 3 and 8). The rolling prevention protrusions 2f and 2f
protrude slightly downward. The imaging device 2 is prevented from
rolling by the rolling prevention protrusions 2f and 2f when the
imaging device 2 is placed on a desk or a table, and thus it is
possible to prevent damage or a failure by the imaging device 2
falling off desk or table or the like.
[0112] In a case where the whole or at least a part of the
circumferential surface part 7a is curved, and the circumferential
surface part 7a forms an outer casing, a rolling prevention
protrusion 2f is useful.
[0113] A zoom switch 2g and a shutter button (image taking button)
2h are arranged in the front and rear direction at the lower end of
the circumferential surface part 7a of the outer barrel 7 (refer to
FIGS. 3 and 9). If the zoom switch 2g is operated, zooming is
performed between telephoto and a wide angle. If the shutter button
2h is operated, a subject is photographed. The zoom switch 2g and
the shutter button 2h are disposed so as to be close to each other,
and thus it is easy for a user to perform a series of image taking
operations in which an angle of view is adjusted through zooming
and then a shutter operation is performed. In addition, the zoom
switch 2g and the shutter button 2h are not only arranged in the
front and rear direction, but may also be disposed at a state of
being arranged in the vertical direction or a tilt direction.
[0114] The shutter button 2h and the zoom switch 2g are disposed at
the same member 2k. This member 2k forms a portion of the
circumferential surface part 7a along with the outer barrel 7. The
zoom switch 2g and the shutter button 2h which are disposed so as
to be close to each other are attached to the member 2k, and the
member 2k is attached to the outer barrel 7, thereby efficiently
assembling the imaging device in terms of manufacturing.
[0115] In addition, the shutter button 2h may be, for example, an
operation part for automatic focusing in a half depressing
operation, and for image taking a subject in a full depressing
operation. For example, assuming that the imaging device 2 is used
singly, there is no display portion (that is, the display device
4), and thus a focusing operation is difficult. If automatic
focusing is performed by half depressing of the shutter button 2h,
it is possible to provide an operation which is intuitively easily
understandable to a user. In addition, if a sound output part is
provided so as to output an electronic sound during the automatic
focusing operation, this is suitable for a user to recognize the
operation.
[0116] Further, the zoom switch 2g is configured in a zoom lever
form as illustrated in the figures. A zooming operation is
performed by operating the lever, and thus operability is improved.
Furthermore, the zoom switch 2g may be in a press button form using
a wide angle button/telephoto button. Moreover, two zoom switches
in a button form and a lever form may be provided.
[0117] Since the zoom switch 2g and the shutter button 2h are
disposed at the left end of the circumferential surface part 7a, an
operating finger is naturally disposed around the zoom switch 2g
and the shutter button 2h when the imaging device 2 is grasped from
the lower side during an image taking operation, and thus it is
possible to improve the convenience for a user in using the imaging
device 2 through the improvement of operability.
[0118] In addition, the zoom switch 2g and the shutter button 2h
are disposed at the left end of the circumferential surface part
7a, and are thus located so as to be separated from the microphones
2c and 2c provided at the upper end of the circumferential surface
part 7a. Accordingly, sounds emitted when a user operates the
shutter button 2h or the zoom switch 2g are not picked up as much
as possible by the microphones 2c and 2c.
[0119] In relation to the zooming operation, the zoom switch 2g and
the above-described operation ring 11 are prepared. Accordingly, a
user can select a zooming operation method in accordance with
circumstances or a preference, and thus the operability is
improved.
[0120] In addition, since the shutter button 2h and the power
button 2d are disposed separately from each other at the upper side
and the lateral side as different positions in the circumferential
direction on the circumferential surface part 7a, it becomes easier
to prevent operation errors in a power operation and an image
taking operation. Further, the shutter button 2h and the power
button 2d may be separated by being disposed at the right and left
sides of the circumferential surface part 7a, but if it is
considered to be appropriate that the power button 2d is disposed
at the upper side of the circumferential surface part 7a as
described above, the shutter button 2h is appropriately disposed
the lateral side (the right or left side) of the circumferential
surface part.
[0121] A cover body 2i is disposed at the rear side of the shutter
button 2h at the left end of the circumferential surface part 7a of
the outer barrel 7. In the imaging device 2, an external connection
terminal such as a universal serial bus (USB) and a memory slot
card (not illustrated) are provided inside the cover body 2i.
Therefore, the cover body 2i is opened, and thus connection to an
external device and installation of a memory card can be performed.
In addition, through the connection to an external device or the
installation of a memory card, an image data or a video data
captured by the imaging device 2 can be recorded in the external
device or the memory card.
[0122] A display part 2j formed by a liquid crystal panel or the
like is disposed at the right end of the circumferential surface
part 7a of the outer barrel 7 (refer to FIG. 10). The display part
2j displays a residual quantity of a battery or whether or not a
memory card is inserted into the memory card slot. The display part
2j is not used to display a captured image data.
[0123] Since the display part 2j is disposed, it is possible to
check a residual quantity of a battery or whether or not a memory
card is inserted into the memory card slot, from the outside of the
imaging device 2, and to thus improve the convenience for a user in
using the imaging device 2.
[0124] The imaging device 2 has a wireless communication function.
By using the wireless communication, for example, it is possible to
perform various operations such as displaying or preserving an
image data or a video data captured by the imaging device 2 on the
display device 4, executing an image taking function of the imaging
device 2 by operating the display device 4, and executing the
zooming function of the imaging device 2 by operating the display
device 4.
[0125] For example, specifically, an NFC part (NFC tag) which
performs near field communication (NFC) is mounted in the inside
close to the upper end of the circumferential surface part 7a in
the outer barrel 7, and performs noncontact communication with an
NFC part mounted in the display device 4. In addition, for example,
wireless fidelity (WIFI) communication part is provided so as to
transmit a captured image data, and performs wireless communication
with a WIFI communication part mounted in the display device 4.
[0126] The imaging device 2 may not only be powered on by operating
the power button 2d as described above, but also be powered on
through the near field communication on the display device 4 side.
For example, if the near field communication is established, the
imaging device 2 is powered on. In addition, if the near field
communication function is displayed around the power button 2d such
as, for example, the upper end of the circumferential surface part
7a, a user can easily understand a power-on operation.
[0127] In addition, since the NFC part is disposed at the upper
side in the outer barrel 7, in a case where the imaging device 2 is
used by installing a tripod in the above-described tripod hole 2e,
the NFC part becomes as close to the display device 4 as possible
easily, which is thus advantageous in noncontact communication.
[0128] Further, as described later in FIG. 37, if a state of the
imaging unit being put on a placing surface 50 is considered, a
user typically makes the display device 4 close to the imaging
device 2 from the upper side. Therefore, the NFC part is disposed
at the upper side in the outer barrel 7, which also is an
arrangement suitable for near field communication in such a
usage.
[0129] In addition, as a position where the NFC part is disposed at
the imaging device 2, examples other than the upper side in the
outer barrel 7 may be considered, but, preferably, the NFC part is
not disposed at least at a position close to the rear surface side
of the outer barrel 7, that is, a position close to the rear
surface part 7c side. This is because, if the NFC part which
performs near field communication is disposed at the rear surface
side, when the imaging device 2 is attached to the display device 4
via the adaptor 3, as in FIGS. 32, 33 and 37, the NFC part may be
in a state of being close to the NFC part of the display device 4
side at all times, and thus polling may occur at all times. For
this reason, the NFC part is preferably disposed at positions other
than the rear surface side of the outer barrel 7.
[0130] In the imaging device 2, for example, operation rings 70 and
70 may be additionally provided to the above-described
configuration (refer to FIG. 11). The operation rings 70 and 70 are
rotatably supported so as to be arranged in the front and rear
direction in the circumferential surface part 7a of the outer
barrel 7. By performing a rotation operation of the operation rings
70 and 70, it is possible to perform changing of various modes in
an image taking operation or reproduction, such as, for example, an
automatic image taking mode, a panorama image taking mode, a
consecutive shot mode, a close-up mode, nighttime image taking
mode, a background blurring mode, a self timer mode, a blur
correction mode, a slide show mode, a still image taking mode, and
a moving image taking mode.
[0131] As mentioned above, the operation rings 70 and 70 are used,
and thus various modes can be changed, thereby further improving
the convenience for a user in using the imaging device 2.
[0132] In addition, any number of operation rings 70 may be used,
and if a plurality of operation rings 70, 70, . . . are provided,
modes which can be set by combinations of respective operation
positions of the operation rings 70, 70, . . . can be increased,
and thus it is possible to improve functionality of the imaging
device 2.
[0133] Further, operation buttons 71, for performing changing of
the various modes may be provided instead of the operation rings 70
and 70 (refer to FIG. 12). The operation buttons 71, 71, . . . are
provided, and thus it is also possible to further improve the
convenience for a user in using the imaging device 2 in the same
manner as providing the operation rings 70 and 70.
[0134] Configuration of Another Imaging Device
[0135] Although the imaging device 2 has been described above, the
following imaging device 2A may be used as a configuration of the
imaging unit 1 instead of the imaging device 2 (refer to FIGS. 13
to 19).
[0136] In addition, the imaging device 2A is the same as the
imaging device 2 except that the imaging device 2A is shorter than
the imaging device 2 and partially has a shape or a function from
the imaging device 2. Therefore, a detailed description will be
made of only portions different from the imaging device 2, and the
other portions are given the same reference numerals as the
reference numerals given to the same portions in the imaging device
2, and the description thereof will be made briefly or omitted.
[0137] The imaging device 2 and the imaging device 2A have, for
example, different zoom magnification, and different image
qualities of captured images.
[0138] The imaging device 2A includes an outer barrel 7A, a
plurality of lens groups disposed inside the outer barrel 7A, and
an imaging element (not illustrated) located on the rear side of
the lens groups. In the imaging device 2A, light incorporated via
the lens groups is subject to photoelectric conversion in the
imaging element. Therefore, the imaging device 2A can capture an
image data or a video data.
[0139] The outer barrel 7A includes a circumferential surface part
7a which is formed in a substantially cylindrical shape extending
from the front side to the rear side, an overhang part 7b which
overhangs inward from a front end of the circumferential surface
part 7a, and a rear surface part 7c which closes the
circumferential surface part 7a from the rear side. The outer
barrel 7A is shorter than the outer barrel 7 in the front and rear
direction.
[0140] Inner barrels 8 and 8 which are extendable in the front and
rear direction are supported inside the outer barrel 7A (refer to
FIGS. 13 and 14).
[0141] An operation ring is not supported in the outer barrel 7A.
In addition, in the imaging device 2A, an operation ring may not be
provided in the same manner as the imaging device 2.
[0142] Coupling parts 12 and 12 which protrude backward are
provided at positions opposite to each other, 180.degree. apart on
an outer circumference of the rear surface part 7c of the outer
barrel 7A (refer to FIG. 15). A lock pin 13 is supported movably in
the front and rear direction around the coupling part 12 of the
rear surface part 7c.
[0143] An unlock lever 2a is disposed at the rear end of the
circumferential surface part 7a of the outer barrel 7A (refer to
FIG. 19). The unlock lever 2a is operated, and thus the lock pin 13
is drawn into the outer barrel 7A.
[0144] A battery lid 2b is disposed at a portion between the
coupling parts 12 and 12 of the rear surface part 7c of the outer
barrel 7A (refer to FIG. 15). An external connection terminal and a
memory card slot are provided inside the battery lid 2b in the
imaging device 2A. In addition, in the imaging device 2A, in the
same manner as the imaging device 2, a cover body may be provided
on the rear side of the shutter button 2h, and an external
connection terminal and a memory card slot may be provided inside
the cover body.
[0145] Microphones 2c and 2c and a power button 2d are disposed
separately from each other in the front and rear direction at the
upper end of the circumferential surface part 7a of the outer
barrel 7A (refer to FIGS. 13 and 16).
[0146] A tripod hole 2e is formed at the lower end of the
circumferential surface part 7a of the outer barrel 7A (refer to
FIG. 17). Rolling prevention protrusions 2f and 2f are provided on
right and left sides of the tripod hole 2e at the lower end of the
circumferential surface part 7a of the outer barrel 7A (refer to
FIGS. 14 and 17). The rolling prevention protrusions 2f and 2f
protrude obliquely outward and downward. The imaging device 2A is
prevented from rolling by the rolling prevention protrusions 2f and
2f when the imaging device 2A is placed on a desk or a table, and
thus it is possible to prevent damage or a failure by the imaging
device 2A falling off desk or table or the like.
[0147] A zoom switch 2g and a shutter button 2h are arranged in the
front and rear direction at the lower end of the circumferential
surface part 7a of the outer barrel 7A (refer to FIGS. 13 and
18).
[0148] A display part 2j formed by a liquid crystal panel or the
like is disposed at the right end of the circumferential surface
part 7a of the outer barrel 7A (refer to FIG. 19).
[0149] The imaging device 2A has a wireless communication function
using NFC, WIFI, a wireless local area network (LAN), or the like.
By using the wireless communication, for example, it is possible to
perform various operations such as displaying or preserving an
image data or a video data captured by the imaging device 2A on the
display device 4, executing an image taking function of the imaging
device 2A by operating the display device 4, and executing the
zooming function of the imaging device 2A by operating the display
device 4.
[0150] Also in the imaging device 2A, in the same manner as the
imaging device 2, the operation rings 70 or the operation buttons
71 may be provided, and thus various modes can be changed, thereby
further improving the convenience for a user in using the imaging
device 2.
[0151] Configuration of Adaptor
[0152] The adaptor 3 includes respective necessary parts disposed
inside and outside a casing 14 (refer to FIGS. 20 to 22).
[0153] The casing 14 is formed by coupling a base body 15 located
on the front side to a cover body 16 located on the rear side.
[0154] The base body 15 includes a base surface part 17 which is
formed in a disc shape, projections 18 and 18 which protrude
backward from the base surface part 17, guide piece parts 19 and 19
which are respectively provided inside the projections 18 and 18,
and a protrusion piece part 20 which protrudes backward from the
base surface part 17 (refer to FIG. 23).
[0155] The projections 18 and 18 are formed in shapes which
protrude from positions opposite to each other, 180.degree. apart
on the outer circumference of the base surface part 17, and extend
in the circumferential direction at both of right and left ends of
the base surface part 17. The projection 18 is opened forward, and
an inner space of the projection 18 is formed as a coupling recess
part 18a (refer to FIG. 20).
[0156] Locking pieces 17a, 17a, . . . which cover a portion of the
coupling recess part 18a from the front side are provided on the
outer circumference of the base surface part 17. A locked hole 17b
which communicates with the coupling recess part 18a is formed in
the base surface part 17.
[0157] The guide piece parts 19 and 19 are formed in a plate shape
which extends in the vertical direction (refer to FIG. 23).
[0158] The protrusion piece part 20 is formed in a plate shape
which protrudes from the lower end of the base surface part 17 and
extends in the horizontal direction.
[0159] A space surrounded by the guide piece parts 19 and 19 and
the protrusion piece part 20 in the base body 15 is formed as a
mechanism arranging space 15a. The protrusion piece part 20 has a
function of shielding a mechanism disposed at the mechanism
arranging space 15a from the outside and of preventing the
mechanism disposed therein from being viewed from the outside of
the adaptor 3.
[0160] The cover body 16 has arrangement notches 16a and 16b whose
exteriors are formed in a circular shape except for a portion
thereof and which are respectively opened upward and downward at
the upper end and lower end (refer to FIGS. 23 and 24).
[0161] A storage recess part 16c which is opened backward and
upward continuously to the lower side of the arrangement notch 16a
is formed in the cover body 16, and a storage recess part 16d which
is opened backward and downward continuously to the upper side of
the arrangement notch 16b is formed therein.
[0162] Both of right and left parts of the cover body 16 are
respectively provided as arrangement parts 21 and 21, and the
arrangement parts 21 and 21 are connected to each other via a
connection part 22. The connection part 22 is a part between the
storage recess parts 16c and 16d.
[0163] The arrangement part 21 is formed in a recess shape which is
opened forward. A protrusion wall 21a which protrude forward and
extends in the vertical direction is provided at the arrangement
part 21.
[0164] An inner space of the protrusion wall 21a of the arrangement
part 21 is formed as a spring arranging space 21b which is opened
forward and is longitudinally long. Upper walls and lower walls
forming the spring arranging spaces 21b and 21b formed in the
arrangement parts 21 and 21 are respectively formed as spring
receiving surfaces 21c and 21c and stopper surfaces 21d and
21d.
[0165] A first slider 23 is supported slidably in the vertical
direction inside the casing 14 (refer to FIGS. 23 and 25). The
first slider 23 has a supported surface part 24 which is formed in
a C shape so as to be opened upward, side surface parts 25 and 25
which protrude backward from both of right and left ends of the
supported surface part 24, and overhang parts 26 and 26 which
protrude in directions of being separated from each other from
upper ends of the side surface parts 25 and 25.
[0166] The first slider 23 is provided with a first spring
receiving surface part 27 which protrudes backward from the lower
end at the left end of the supported surface part 24. The first
slider 23 is provided with a protrusion receiving surface part 28
which protrudes backward from the lower end at the right end of the
supported surface part 24. The first slider 23 is provided with a
second spring receiving surface part 29 which protrudes backward
from the upper end at the right end of the supported surface part
24.
[0167] In the first slider 23, parts other than the overhang parts
26 and 26 are inserted into and disposed at the mechanism arranging
space 15a, and the overhang parts 26 and 26 are disposed so as to
cover the guide piece parts 19 and 19 of the base body 15 from the
rear side. In the first slider 23, the side surface parts 25 and 25
are guided to the guide piece parts 19 and 19 so as to be slid in
the vertical direction.
[0168] In a state in which the first slider 23 is disposed as
described above, a first biasing spring 30 is disposed between the
first spring receiving surface part 27 and one spring receiving
surface 21c of the cover body 16. The first biasing spring 30 is,
for example, a compression coil spring, and both ends thereof are
pressed toward the first spring receiving surface part 27 and the
spring receiving surface 21c. Therefore, the first slider 23 is
biased downward by the first biasing spring 30. If the first slider
23 is biased downward by the first biasing spring 30, the first
spring receiving surface part 27 is pressed toward the left stopper
surface 21d of the cover body 16, and thus a downward movement of
the first slider 23 is restricted.
[0169] A second slider 31 is supported slidably in the vertical
direction on the rear side of the first slider 23 inside the casing
14. The second slider 31 has a base surface part 32 which is formed
in a substantially rectangular shape which is longitudinally long,
and a protrusion surface part 33 which protrude to the right from
the right end at the lower end of the base surface part 32.
[0170] The second slider 31 is provided with a spring support
surface part 34 which protrude backward from the lower end of the
protrusion surface part 33. The second slider 31 is provided with a
notch 35 for escape which is opened downward at the lower end of
the base surface part 32.
[0171] In the second slider 31, the base surface part 32 is
attached to and held in a decorative panel 36. The decorative panel
36 includes a holding base 36a which has a longitudinally long and
substantially rectangular shape, and side wall parts 36b and 36b
which protrude backward from both of right and left ends of the
h36a. The base surface part 32 is held in the decorative panel 36
in a state of being installed on the rear surface of the holding
base 36a and being surrounded from the lateral sides by the side
wall parts 36b and 36b.
[0172] The second slider 31 is inserted into and disposed at the
mechanism arranging space 15a in a state of being held in the
decorative panel 36. The side wall parts 36b and 36b of the
decorative panel 36 are guided to the respective inner surfaces of
the arrangement parts 21 and 21 of the cover body 16, and thus the
second slider 31 is slid in the vertical direction.
[0173] In a state in which the second slider 31 is disposed as
described above, a second biasing spring 37 is disposed between the
spring support surface part 34 and the second spring receiving
surface part 29 of the first slider 23. The second biasing spring
37 is, for example, a compression coil spring, and both ends
thereof are pressed toward the spring support surface part 34 and
the second spring receiving surface part 29. Therefore, the second
slider 31 is biased downward by the second biasing spring 37. If
the second slider 31 is biased downward by the second biasing
spring 37, the spring support surface part 34 is pressed toward the
protrusion receiving surface part 28 of the first slider 23, as a
result, the protrusion receiving surface part 28 is pressed toward
the right stopper surface 21d of the base body 15, and thus a
downward movement of the second slider 31 is restricted.
[0174] A spring force of the first biasing spring 30 is smaller
than a spring force of the second biasing spring 37.
[0175] As described above, the first biasing spring 30 is disposed
between the first spring receiving surface part 27 of the first
slider 23 and one spring receiving surface 21c of the cover body
16, and the second biasing spring 37 is disposed between the spring
support surface part 34 of the second slider 31 and the second
spring receiving surface part 29 of the first slider 23. Therefore,
the first biasing spring 30 and the second biasing spring 37 are
connected in series to each other via the first slider 23.
Therefore, the second slider 31 is biased downward by the first
biasing spring 30 and the second biasing spring 37.
[0176] A first attached body 38 is supported rotatably at the upper
end of the base surface part 32 of the second slider 31. The first
attached body 38 has a pinch part 39 which is supported in the base
surface part 32 and has a substantially plate shape, and a holding
protrusion 40 which protrudes from a front end of the pinch part 39
in a direction perpendicular to the pinch part 39.
[0177] The first attached body 38 is disposed at the arrangement
notch 16a formed in the cover body 16 in a state in which the base
body 15 is coupled to the cover body 16.
[0178] The first attached body 38 may be stored in the storage
recess part 16c in a first state so as to take a storage position
(refer to FIG. 21) of being closed for the first slider 23. In
other words, the first attached body 38 is in a state of being
stored in the base body 15.
[0179] In addition, the first attached body 38 may take a holding
position (refer to FIG. 22) of being opened for the first slider 23
in a second state. The first attached body 38 is rotatably moved
between the storage position (first state) and the holding position
(second state).
[0180] The first attached body 38 is in a state of protruding
backward from the cover body 16 at the holding position.
[0181] An elastic body 41 is provided inside the pinch part 39
(refer to FIG. 26). The elastic body 41 is formed by integrally
forming a plate-shaped surface-shaped part 41a attached to the
pinch part 39, pushing protrusions 41b and 41b which protrude from
a central part of the surface-shaped part 41a in the horizontal
direction, and pressing protrusions 41c, 41c, . . . which are
located on the right and left sides of the pushing protrusions 41b
and 41b which protrude from the surface-shaped part 41a together by
using a rubber material.
[0182] The pushing protrusions 41b and 41b are elastically
deformable, are provided separately from each other in the
horizontal direction, and are formed so as to extend in the front
and rear direction in a state in which the first attached body 38
is rotatably moved to the holding position. The pushing protrusions
41b and 41b are tilted so as to be horizontally separated from each
other in the protruding directions.
[0183] The pressing protrusions 41c, 41c, . . . are elastically
deformable, are provided separately from each other in the vertical
direction, and are formed so as to extend in the horizontal
direction. The pressing protrusions 41c, 41c, . . . are tilted so
as to be close to the holding protrusion 40 in the protruding
directions.
[0184] A support plate 42 is attached to the lower end side of the
central part of the cover body 16 in the horizontal direction. A
portion of the support plate 42 is located in the notch 35 for
escape formed in the second slider 31 in a state in which the base
body 15 is coupled to the cover body 16, and thus interference
between the support plate 42 and the second slider 31 is
prevented.
[0185] A second attached body 43 is rotatably supported at the
lower end of the support plate 42. The second attached body 43 has
a pinch part 44 which is supported in the support plate 42 and has
a substantially plate shape, and a holding protrusion 45 which
protrudes from a front end of the pinch part 44 in a direction
perpendicular to the pinch part 44.
[0186] The second attached body 43 is disposed at the arrangement
notch 16b formed in the cover body 16 in a state in which the base
body 15 is coupled to the cover body 16. The second attached body
43 is stored in the storage recess part 16d, and is rotatably moved
between a storage position (refer to FIG. 21) of being closed for
the base body 15 and a holding position (refer to FIG. 22) of being
opened for the base body 15. The second attached body 43 is in a
state of protruding backward from the cover body 16 at the holding
position.
[0187] The same elastic body 41 as that provided inside the pinch
part 39 of the first attached body 38 is provided inside the pinch
part 44 (refer to FIG. 26).
[0188] As described above, since the first attached body 38 and the
second attached body 43 are respectively stored in the storage
recess parts 16c and 16d, the adaptor 3 can be carried or kept in a
state in which the first attached body 38 and the second attached
body 43 are stored when not used, and thus it is possible to
improve a handling property when not used.
[0189] In addition, since the first attached body 38 and the second
attached body 43 are respectively stored in the storage recess
parts 16c and 16d when the adaptor 3 is not used, the first
attached body 38 and the second attached body 43 do not protrude
from the cover body 16, and the first attached body 38 and the
second attached body 43 can be prevented from being damaged or
scratched.
[0190] Attachment and Detachment of Adaptor to and from Imaging
Device
[0191] The adaptor 3 with the above-described configuration is
coupled to the imaging device 2 or 2A in the following manner.
[0192] First, the coupling parts 12 and 12 of the imaging device 2
or 2A are respectively inserted into the coupling recess parts 18a
and 18a formed in the base body 15 of the adaptor 3.
[0193] Next, the adaptor 3 is rotated about the imaging device 2 or
2A. If the adaptor 3 is rotated, the locking pieces 17a, 17a, . . .
of the adaptor 3 are respectively engaged with the locking
protrusions 12a, 12a, . . . of the imaging device 2 or 2A, and thus
a movement of the adaptor 3 is restricted in the front and rear
direction with respect to the imaging device 2 or 2A. In other
words, the locking protrusions form a state of being engaged with
the locking pieces 17a and 17a of the adaptor 3.
[0194] At this time, simultaneously, the lock pin 13 of the imaging
device 2 or 2A is pressed by the base body 15, as a result, the
lock pin 13 is drawn into the outer barrel 7 against a biasing
force of the spring so that the adaptor 3 is rotated to a
predetermined position and the locked hole 17b matches the lock pin
13. In addition, the lock pin 13 is made to protrude from the outer
barrel 7 by the spring and is thus inserted into the locked hole
17b.
[0195] When the lock pin 13 is inserted into the locked hole 17b,
rotation of the adaptor 3 for the imaging device 2 or 2A is
restricted, and the adaptor 3 is coupled to the imaging device 2 or
2A in a locked state.
[0196] As described above, the imaging device 2 and the adaptor 3
are relatively rotated via the coupling parts 12 and 12, and thus
the imaging device 2 and the adaptor 3 can be easily coupled to
each other. In addition, the coupling state is maintained by the
lock pin 13.
[0197] First and second coupling parts 12 and 12 which protrude
backward are provided at positions opposite to each other,
180.degree. apart on an outer circumference of the rear surface
part 7c of the outer barrel 7 (refer to FIGS. 3 and 6). Locking
protrusions 12a and 12a which protrude outward separately in a
circumferential direction are respectively provided at the coupling
parts 12 and 12. A lock pin 13 is supported movably in the front
and rear direction around the coupling part 12 of the rear surface
part 7c, and the lock pin 13 is biased backward by a spring (not
illustrated).
[0198] The unlock lever 2a is operated so that the lock pin 13 is
drawn into the outer barrel 7, and the adaptor 3 is rotated about
the imaging device 2 or 2A in a direction opposite to the time of
the coupling in the unlocked state, thereby performing decoupling
of the adaptor 3 from the imaging device 2 or 2A. If the adaptor 3
is rotated about the imaging device 2 or 2A in a direction opposite
to the time of the coupling, the engagement state between the
locking pieces 17a, 17a, . . . and the locking protrusions 12a,
12a, . . . of the imaging device 2 or 2A is canceled. The adaptor 3
is moved backward with respect to the imaging device 2 or 2A in
this state, and the coupling parts 12 and 12 are extracted from the
coupling recess parts 18a and 18a, thereby decoupling the adaptor 3
from the imaging device 2 or 2A.
[0199] Operation During Attachment and Detachment of Adaptor to and
from Display Device
[0200] Hereinafter, a description will be made of an operation
during attachment and detachment of the adaptor 3 to and from the
display device 4 (refer to FIGS. 27 to 33).
[0201] In a state in which the adaptor 3 is not attached to the
display device 4, a downward movement of the first slider 23 is
restricted since the first spring receiving surface part 27 is
pressed toward the left stopper surface 21d of the cover body 16 by
the biasing force of the first biasing spring 30 (refer to FIG.
27). In this case, a downward movement of the second slider 31 is
restricted since the spring support surface part 34 is pressed
toward the protrusion receiving surface part 28 of the first slider
23 by the second biasing spring 37, and the protrusion receiving
surface part 28 is pressed toward the right stopper surface 21d of
the base body 15.
[0202] The first attached body 38 and the second attached body 43
are respectively extracted from the storage recess parts 16c and
16d of the cover body 16 and are rotatably moved to the holding
positions, thereby performing attachment of the adaptor 3 to the
display device 4.
[0203] When the adaptor 3 is attached to the display device 4, the
first attached body 38 is grasped and moved upward.
[0204] When the first attached body 38 is moved up, first, the
second slider 31 is moved up along with the movement of the first
attached body 38 (refer to FIG. 28). If the second slider 31 is
moved upward, the second biasing spring 37 is compressed.
[0205] Further, if the second slider 31 is moved upward along with
the movement of the first attached body 38, the second biasing
spring 37 is compressed, and, simultaneously, the second spring
receiving surface part 29 is pressed upward and the first slider 23
is moved upward due to the compression of the second biasing spring
37 (refer to FIG. 29). When the first slider 23 is moved upward,
the first biasing spring 30 is compressed. Therefore, the second
biasing spring 37 and the first biasing spring 30 are
simultaneously compressed.
[0206] As described above, if the first attached body 38 is moved
upward, the first attached body 38 is spaced far apart from the
second attached body 43. The first attached body 38 is moved upward
to a position corresponding to a size of the display device 4 to be
attached (refer to FIGS. 30 and 31).
[0207] Next, the display device 4 is pinched by the first attached
body 38 and the second attached body 43, and thus the adaptor 3 is
attached to the display device 4 (refer to FIGS. 32 and 33). At
this time, the first attached body 38 is biased to the second
attached body 43 in a direction of being close thereto by the first
biasing spring 30 and the second biasing spring 37, and the elastic
bodies 41 and 41 are in close contact with the display device
4.
[0208] In a state in which the adaptor 3 is attached to the
small-sized display device 4, a gap between the first attached body
38 and the second attached body 43 is small (refer to FIG. 32),
and, in a state in which the adaptor 3 is attached to the
large-sized display device 4, a gap between the first attached body
38 and the second attached body 43 is large (refer to FIG. 33).
[0209] In a state in which the adaptor 3 is attached to the display
device 4, the holding protrusion 40 of the first attached body 38
and the holding protrusion 45 of the second attached body 43 is in
a state of going around to the rear surface side of the display
device 4. Therefore, the adaptor 3 is prevented from falling
forward from the display device 4.
[0210] As illustrated in FIG. 32 or FIG. 33, when attached to the
display device 4, the adaptor 3 has a configuration in which the
second attached body 43 is set to a fixed position, and the first
attached body 38 side is extended. Only the first attached body 38
which is an upper side is extended and contracted, and a gap
between the first attached body 38 and the second attached body 43
is adjusted. Therefore, an imaging optical axis of the imaging
device 2 is located at a position which is equal to or lower than a
central point in the height direction (the short side direction of
the casing of the display device 4) of the display panel 6 of the
display device 4. In addition, a bottom position of the imaging
device 2 and a bottom position of the display device 4
substantially match each other regardless of a size of the display
device 4.
[0211] For this reason, a user can easily and stably hold the
display device 4 attached with the imaging unit 1 regardless of the
display device 4. In addition, even in a case where the display
device 4 attached with the imaging unit 1 is placed on a desk or
the like as it is, a posture thereof is stable, and thus the
display device 4 attached therewith is also suitable for imaging in
this state.
[0212] In addition, the second attached body 43 is set to a fixed
position, and thus there is an advantage in that an attachment
state of the adaptor 3 to the display device 4 is stable.
[0213] A mark 48 which indicates a configuration in which the first
attached body 38 side extends upward is provided at the adaptor 3
as illustrated in FIGS. 30 and 31. The mark 48 allows a user to
recognize that a position of the first attached body 38 extends
upward, and thus the user can easily understand an attached part
during attachment to the display device 4. Therefore, it is
possible to improve usability.
[0214] The first attached body 38 is grasped, and the first
attached body 38 is moved upward along with the second slider 31 so
that the display device 4 is extracted between the first attached
body 38 and the second attached body 43, thereby removing the
adaptor 3 from the display device 4. If the upward force given to
the first attached body 38 is removed after the display device 4
extracted between the first attached body 38 and the second
attached body 43, the first attached body 38 is moved downward
along with the second slider 31 and the first slider 23, and the
first slider 23 and the second slider 31 are returned to an
original state before being attached to the display device 4, by
the biasing forces of the first biasing spring 30 and the second
biasing spring 37.
[0215] Operation Due to Series Connection Between First Biasing
Spring and Second Biasing Spring
[0216] As described above, in the adaptor 3, the first biasing
spring 30 and the second biasing spring 37 are connected in series
to each other via the first slider 23, and the second biasing
spring 37 and the first biasing spring 30 are simultaneously
compressed due to a sliding operation of the first slider 23.
[0217] A description will be made of an operation when the second
biasing spring 37 and the first biasing spring 30 are
simultaneously compressed (refer to FIG. 34).
[0218] FIG. 34 is a graph in which a transverse axis expresses an
extension amount (compression amount) and a longitudinal axis
expresses a spring force (strength). In the imaging unit 1, the
display devices 4 having different sizes are preferably pinched at
a constant force by the first attached body 38 and the second
attached body 43, and, ideally, a spring force is constant even in
a state in which an extension amount of the spring varies (state
A).
[0219] The state B and the state C illustrated in the graph
respectively indicate relationships between extension amounts of
the first biasing spring and the second biasing spring having
different spring forces and strengths, and are considerably tilted
relative to the state A.
[0220] On the other hand, the state D indicates a relationship
between an extension amount and a strength when the first biasing
spring and the second biasing spring are connected in series to
each other, and the state D has a tilt angle relative to the state
A, smaller than the states B and C, and is thus a state close to
the ideal state A.
[0221] Therefore, as in the adaptor 3, the first biasing spring 30
and the second biasing spring 37 are connected in series to each
other, and the second biasing spring 37 and the first biasing
spring 30 are simultaneously compressed due to the sliding
operation of the first slider 23. Thus, a variation in a downward
biasing force to the first attached body 38 is small when a gap
between the first attached body 38 and the second attached body 43
varies.
[0222] Operation of Pushing Protrusion and Pressing Protrusion of
Adaptor
[0223] As described above, in a state in which the display device 4
is pinched by the first attached body 38 and the second attached
body 43, and the adaptor 3 is attached to the display device 4, the
pushing protrusions 41b, 41b, . . . and the pressing protrusions
41c, 41c, . . . of the elastic bodies 41 and 41 are in close
contact with the display device 4.
[0224] In a state in which the display device 4 is in close contact
with the pushing protrusions 41b, since the pushing protrusions
41b, 41b, . . . are elastically deformable, and the second attached
body 43 is biased in a direction of being close to the first
attached body 38 by the first biasing spring 30 and the second
biasing spring 37, the pushing protrusions 41b, 41b, . . . which
are tilted with respect to the protruding direction from the
surface-shaped part 41a are elastically deformed, and are crushed
between the display device 4 and the surface-shaped part 41a (refer
to FIG. 35).
[0225] Therefore, a contact area of the pushing protrusions 41b,
41b, . . . with the display device 4 increases, and it is possible
to effectively prevent the adaptor 3 from falling off the display
device 4.
[0226] In addition, although, in the above description, the
arranged pushing protrusions 41b and 41b are tilted so as to be
separated from each other in the arrangement direction and in the
protruding directions from the surface-shaped part 41a, conversely,
the arranged pushing protrusions 41b and 41b may be tilted so as to
be close to each other in the arrangement direction and in the
protruding directions from the surface-shaped part 41a.
[0227] Further, in a state in which the pressing protrusions 41c,
41c, . . . are in close contact with the display device 4, since
the since the pressing protrusions 41c, 41c, . . . are elastically
deformable, and the second attached body 43 is biased in a
direction of being close to the first attached body 38 by the first
biasing spring 30 and the second biasing spring 37, the pressing
protrusions 41c, 41c, . . . which are tilted with respect to the
protruding direction from the surface-shaped part 41a are
elastically deformed, and are crushed between the display device 4
and the surface-shaped part 41a (refer to FIG. 36).
[0228] Therefore, a contact area of the pressing protrusions 41c,
41c, . . . with the display device 4 increases, and it is possible
to effectively prevent the adaptor 3 from falling off the display
device 4.
[0229] In addition, since the pressing protrusions 41c, 41c, . . .
are tilted so as to be separated from each other at rotatable
movement points of the first attached body 38 and the second
attached body 43 about the first slider 23 or the base body 15 in
the protruding directions, it is difficult for the first attached
body 38 and the second attached body 43 to be moved to an opposite
side to the front end sides of the first attached body 38 and the
second attached body 43 with respect to the display device 4, and
thus it is possible to more effectively prevent the adaptor 3 from
falling off the display device 4.
[0230] In addition, since the pressing protrusions 41c, 41c, . . .
are provided in plurality separately from each other in directions
which connect the rotatable movement directions of the first
attached body 38 and the second attached body 43 to the front ends
thereof, a contact area with the display device 4 considerably
increases, and thus it is possible to further more effectively
prevent the adaptor 3 from falling off the display device 4.
[0231] Usage and the Like of Imaging Unit
[0232] As described above, the adaptor 3 attached to the imaging
device 2 or 2A is attached to the display device 4, that is, the
imaging device 2 or 2A is attached to the display device 4 via the
adaptor 3, thereby forming the imaging unit 1.
[0233] In a state in which the adaptor 3 is attached to the display
device 4, the first attached body 38 and the second attached body
43 are rotatably moved to the holding positions. In this state, for
example, the first attached body 38 or the second attached body 43
and the display device 4 are placed on a placing surface 50 of a
desk or the like, and thus the imaging unit 1 can be used in a
stationary state (refer to FIG. 37).
[0234] As mentioned above, the first attached body 38 and the
second attached body 43 has a function of attaching the adaptor 3
to the display device 4, and also has a function of a stand for
using the imaging unit 1 in a stationary state. Therefore, it is
possible to improve the convenience for a user through the
improvement of the functionality.
[0235] In addition, a capturing operation of an image data or a
video data is the same in both of a portable state and a stationary
state of the imaging unit 1, and an image data or a video data
acquired by the imaging device 2 or 2A is displayed on the display
panel 6 of the display device 4 through wireless communication
between the imaging device 2 or 2A and the display device 4. A
photographer may capture the image data or the video data acquired
by the imaging device 2 or 2A by checking a screen displayed on the
display panel 6, and by operating the shutter button 2h of the
imaging device 2 or 2A or operating a predetermined operation part
of the display panel 6 which is a touch panel.
[0236] Examples in which the Number of Biasing Springs is
Different
[0237] Although, in the above description, the adaptor 3 in which
two biasing springs including the first biasing spring 30 and the
second biasing spring 37 are provided has been described as an
example, the adaptor may include, for example, three or more
biasing springs.
[0238] Hereinafter, a description will be made of an adaptor 3A
including three biasing springs (refer to FIG. 38). In addition,
the adaptor 3A described below is an example in which an adaptor
according to an embodiment of the present technology can be formed
using three or more biasing springs, and a configuration or the
like thereof will be conceptually described below.
[0239] The adaptor 3A includes a first slider 23, a second slider
31, and a third slider 46 which all can be slid in the vertical
direction. A second biasing spring 37 is supported between the
first slider 23 and the second slider 31; a first biasing spring 30
is supported between the first slider 23 and the third slider 46;
and a third biasing spring 47 is supported between the third slider
46 and the cover body 16.
[0240] Therefore, in the adaptor 3A, the second biasing spring 37,
the first biasing spring 30, and the third biasing spring 47 are
connected in series to each other via the first slider 23 and the
third slider 46.
[0241] A spring force of the first biasing spring 30 is smaller
than a spring force of the second biasing spring 37, and a spring
force of the third biasing spring 47 is smaller than the spring
force of the first biasing spring 30.
[0242] In the adaptor 3A, if the second slider 31 is moved due to a
movement of the first attached body 38, the second biasing spring
37 is compressed so that the spring force of the second biasing
spring 37 is applied to the first slider 23, and thus the first
slider 23 is moved in the same direction as the second slider 31
(refer to FIG. 39). In addition, if the first slider 23 is moved,
the first biasing spring 30 is compressed so that the spring force
of the first biasing spring 30 is applied to the third slider 46,
and thus the third slider 46 is moved in the same direction as the
first slider 23. Further, if the third slider 46 is moved, the
third biasing spring 47 is compressed.
[0243] As mentioned above, in the adaptor 3A, the second biasing
spring 37, the first biasing spring 30, and the third biasing
spring 47 are connected in series to each other via the first
slider 23 and the third slider 46, and the second biasing spring
37, the first biasing spring 30, and the third biasing spring 47
are simultaneously compressed due to the sliding operation of the
first slider 23. Therefore, a variation in a biasing force to the
first attached body 38 is small when a gap between the first
attached body 38 and the second attached body 43 varies.
[0244] In addition, in the adaptor according to the embodiment of
the present technology, four or more biasing springs may be
connected in series to each other via sliders.
[0245] One Embodiment of Imaging Unit
[0246] Hereinafter, a description will be made of a block diagram
of an imaging unit according to an embodiment of the present
technology (refer to FIG. 45).
[0247] The imaging unit 1 includes the imaging device 2 (2A) and
the adaptor 3 (3A).
[0248] The imaging device 2 (2A) includes lens groups 52 which are
arranged in an optical axis direction; an imaging element 53 which
performs light incorporated via the lens groups 52 on photoelectric
conversion; a camera signal processing portion 54 which performs a
signal process such as analog-digital conversion of an image data
captured by the imaging element 53; and an image data processing
portion 55 which performs recording and reproducing processes of
the image data. In addition, the imaging device includes a
reader/writer (R/W) 56 which reads and writes an image data from
and to a memory card 100; a central processing unit (CPU) 57 which
controls the entire imaging device 2 (2A); an input operation
portions 58, (the zoom switch 2g, the shutter button 2h, and the
like) such as various switches which allow a user to perform a
necessary operation; and an NFC part 59.
[0249] The camera signal processing portion 54 performs various
signal processes such as conversion into a digital signal, noise
removal, image quality correction, and conversion into a
luminance/color difference signal, on an output signal from the
imaging element 53.
[0250] The image data processing portion 55 performs a compression
encoding process or a decompression decoding process of an image
data based on a predetermined image data format, or a conversion
process of a data standard such as a resolution.
[0251] The R/W 56 writes an image data encoded by the image data
processing portion 55 to the memory card 100 and reads an image
data recorded in the memory card 100.
[0252] The CPU 57 functions as a control process portion which
controls the respective portions provided in the imaging device 2
(2A), and controls the respective portions on the basis of an
instruction input signal from the input operation portions 58, 58,
. . . .
[0253] In addition, the CPU 57 can transmit and receive a variety
of data and control information to and from the display device 4
side through wireless communication performed by the communication
part 59 having the above-described NFC part or WIFI communication
part.
[0254] The input operation portions 58, 58, . . . output an
instruction input signal corresponding to an operation performed by
a user, to the CPU 57.
[0255] The memory card 100 is, for example, a semiconductor memory
which is attachable to and detachable from a memory card slot
connected to the R/W 56.
[0256] Hereinafter, an operation of the imaging device 2 (2A) will
be described.
[0257] If a shutter (not illustrated) is operated in response to an
instruction input signal from the input operation portions 58, 58,
. . . , a captured image data is output to the image data
processing portion 55 from the camera signal processing portion 54
so as to undergo a compression encoding process, and is converted
into digital data with a predetermined data format. The converted
data is output to the R/W 56 so as to be written to the memory card
100. In addition, the converted data may be transmitted to the
display device 4 through wireless communication so as to be output
to the display panel 6, or so as to be written to a recording
portion of the display device 4.
[0258] In a case where of reproducing the image data recorded in
the memory card 100, the predetermined image data is read by the
R/W 56 from the memory card 100 in response to an operation on the
input operation portions 58, 58, . . . , so as to undergo a
decompression decoding process in the image data processing portion
55, and then a reproduced image data is transmitted to the display
device 4 through the wireless communication so as to be output to
the display panel 6, thereby displaying a reproduced image.
[0259] Battery Mounting Structure
[0260] A description will be made of a battery mounting structure
in the above-described imaging device 2 with reference to FIGS. 40
to 44.
[0261] FIG. 40 illustrates a rear surface of the battery lid 2b and
a battery mounting part 70 which is exposed to the rear surface
part 7c side of the outer barrel 7 by opening the battery lid
2b.
[0262] Four slide claws 61 are provided on the rear surface of the
battery lid 2b. In addition, a flexible connection member 62 which
is positioned in a state of being inserted into bosses 63, 63, . .
. is attached to the rear surface of the battery lid 2b. The
flexible connection member 62 is fixed to the rear surface of the
battery lid 2b through caulking to the bosses 63 or adhesion to
rear surface of the battery lid 2b. A front end 62a of the flexible
connection member 62 extends so as to protrude from the plane of
the battery lid 2b, and the front end 62a is inserted into an
insertion hole 72 provided at the upper side of the battery
mounting part 70.
[0263] FIG. 40 illustrates, for description, a state in which the
battery lid 2b is removed from the outer barrel 7, but, normally,
in a case where the battery lid 2b is dislocated, the front end 62a
of the flexible connection member 62 is locked in a state of being
inserted into the insertion hole 72 as in FIG. 41. In other words,
the flexible connection member 62 forms a hinge mechanism between
the outer barrel 7 and the battery lid 2b. Accordingly, even in a
state in which the battery lid 2b is opened, the battery lid 2b
does not fall from the outer barrel 7. In addition, since the front
end 62a has a length to an extent, the battery lid 2b can be moved
freely to an extent with respect to the outer barrel 7.
[0264] The battery mounting part 70 is a recessed space in which a
flat square battery 90 illustrated in FIG. 41 can be installed.
Electrode terminals 71, 71 and 71 which are in contact with
electrode terminals 91, 91 and 91 of the battery 90 are formed at
the upper side of the battery mounting part 70. FIG. 42 illustrates
a state in which the battery 90 is mounted in the battery mounting
part 70, and the electrode terminals 91, 91 and 91 are in contact
with the electrode terminals 71, 71 and 71 in this state.
[0265] Locking rails 74 and 74 for attaching the battery lid 2b are
formed on the right and left on the rear side of the space as the
battery mounting part 70, and two notch parts 73 and 73 are formed
in each of the two locking rails 74 and 74.
[0266] A total of four notch parts 73 are formed at positions
corresponding to the four slide claws 61 of the rear surface of the
battery lid 2b.
[0267] If the battery lid 2b is to be closed, the rear surface of
the battery lid 2b is put on the rear surface part 7c side of the
outer barrel 7, and the four slide claws 61 are respectively fitted
into the four notch parts 73 as illustrated in FIG. 43. In
addition, in this state, the battery lid 2b is slid, which leads to
a state of FIG. 44. Accordingly the slide claws 61 are locked in
the locking rails 74 and 74, and thus the battery lid 2b is in a
closed state.
[0268] In a case of opening the battery lid 2b, the battery lid 2b
is slid downward conversely. In addition, for this operation, as
illustrated in FIG. 44, minute protrusions 65 for holding the
finger or a mark 66 indicating a slide direction is preferably
formed on the front surface side of the battery lid 2b.
[0269] If a user slides the battery lid 2b downward, the four slide
claws 61 are respectively moved to the positions of the four notch
parts 73 as illustrated in FIG. 43. When the battery lid 2b is
raised in this state, the lid is opened as illustrated in FIG.
41.
[0270] As described above, the battery 90 is mounted in the battery
mounting part 70 formed in the rear surface part 7c side of the
outer barrel 7. In this case, the flat battery 90 is mounted in a
posture in which the plane thereof is perpendicular to the imaging
optical axis of the imaging device 2. In a case where the battery
90 is mounted in parallel to the imaging optical axis, a shaped
part for storing a remaining battery is necessarily formed in a
substantially cylindrical shape of the outer barrel 7, but if the
battery 90 is stored in a vertical posture along the rear surface
part 7c, this does not influence the shape of the outer barrel.
Accordingly, a degree of freedom of design of the imaging device 2
increases.
[0271] In addition, as described above, the battery mounting part
70 is provided at the rear surface part 7c, which is thus suitable
for miniaturization of the entire imaging device 2 in relation to a
substrate (not illustrated) inside the outer barrel 7. For example,
the substrate on which the imaging element is disposed is arranged
so as to be perpendicular to the optical axis, but the battery
storage space is formed in parallel to the substrate, which is thus
suitable for reducing a casing size in the optical axis
direction.
[0272] The battery 90 is attachable and detachable, and thus can be
changed to a preliminary battery, thereby providing convenience in
use.
[0273] In addition, in a case where opening the battery lid 2b,
since the battery lid 2b has only to be slid downward and raised,
the operation is simple, and a degree of freedom of a position is
high in a state in which the battery lid does not fall by the
flexible connection member 62. For this reason, the battery lid 2b
is not impeded, and the battery lid 2b is prevented from being
lost, in a case of exchange batteries, and the like.
[0274] Since the upper side of the battery lid 2b is connected to
the outer barrel 7 by the flexible connection member 62, the
battery lid 2b is easily located so as to naturally cover the
battery mounting part 70. For this reason, it becomes easier for a
user to put the slide claws 61 at the positions of the notch parts
73, and the battery lid 2b can be closed through a very simple
operation in which the battery lid is slid upward as it is.
[0275] The battery lid 2b is provided, and thus the rear surface
part 7c looks good. In addition, it is possible to prevent a
battery from falling off.
[0276] In addition, the sliding during opening and closing of the
battery lid 2b is performed along the locking rails 74 and 74, but
this is performed in a state of avoiding the coupling parts 12 and
12. Therefore, a function of the coupling parts 12 and 12 is not
impeded. Of course, the coupling parts 12 and 12 have a fixed
structure which is not slid, and, in relation to this fact, a
function of the coupling parts 12 and 12 is maintained regardless
of sliding of the battery lid 2b.
[0277] In addition, the battery lid 2b has a structure of being
slid downward, and thus the shape of the battery lid is not exposed
to the upper side of the outer barrel 7. For example, as
illustrated in FIG. 8, the battery lid 2b is exposed to the lower
side, and the boundary with the battery lid 2b is viewed on the
circumferential surface of the outer barrel 7. If this boundary is
viewed on the upper side, this impairs the appearance. In other
words, by using the downward sliding structure, the appearance of
the upper side can be improved, and thus the appearance looks
good.
[0278] Others
[0279] Although, in the above description, a description has been
made of an example in which all of the first biasing spring 30, the
second biasing spring 37, and the third biasing spring 47 are
compression coil springs, these biasing springs may be different
kinds of springs, and may be, for example, tensile coil
springs.
[0280] In addition, although, in the above description, a
description has been made of an example in which the first attached
body 38 is moved in the vertical direction in a state of being
biased in a direction of being close to the second attached body
43, for example, the first attached body 38 and the second attached
body 43 may be respectively moved in the vertical direction in a
state of being biased in a direction in which both two bodies are
close to each other. In this case, a sliding mechanism which allows
the second attached body 43 to be moved in the vertical direction
may be provided, and biasing forces of a plurality of springs which
are connected in series to each other may be applied to the second
attached body 43.
[0281] The imaging device 2 has been described as having a
substantially cylindrical shape, but a shape of the imaging device
2 is not limited. For example, as illustrated in FIG. 46, an outer
barrel shape of the imaging device 2 may be a substantially
rectangular parallelepiped shape.
[0282] Conclusion
[0283] In the above-described embodiment, the imaging unit 1
includes the imaging device 2 and the adaptor 3.
[0284] Since the imaging unit is formed by the imaging device and
the installation portion, the imaging device can be attached to an
external display device so as to be used.
[0285] The imaging device 2 includes the communication part 59
which transmits an image data to an external device, the outer
barrel 7 in which at least lens is disposed, the imaging element
53, the image taking button (shutter button 2h), and the power
button 2d. In addition, the zoom switch 2g is included. Further,
the rolling prevention part (rolling prevention protrusions 2f and
2f) which prevents the device casing from rolling in a placed
state.
[0286] In addition, the circumferential surface part 7a is provided
at the outer barrel 7; the shutter button 2h is disposed, for
example, on the right side of the circumferential surface part 7a;
the power button 2d is disposed at the upper side of the
circumferential surface part 7a; and the zoom switch 2g is disposed
at the circumferential surface part 7a.
[0287] As described above, the imaging device 2 is suitable as a
device which performs an imaging operation and/or a display
operation in cooperation with an external display device.
Particularly, since the imaging element 53, the shutter button 2h,
the power button 2d, and the zoom switch 2g are provided at the
circumferential surface part 7a, the rear surface side can be
attached to a display device, and thus it becomes easier to
implement the imaging device 2 with a shape suitable for the
cooperation with the display device.
[0288] In addition, the imaging device 2 is not provided with a
display part which is used to display a captured image data
obtained by the imaging element 53. Accordingly, it becomes easier
to realize miniaturization of an imaging device which is cooperated
with an external display device, and it becomes easier to implement
an imaging device with a shape suitable for attachment to an
external display device.
[0289] The circumferential surface part 7a is formed by a plurality
of members. In other words, the circumferential surface part 7a is
not only formed by an integrated component as the outer barrel 7,
but is also formed by a combination with other components, for
example, a member 2k or the like. Accordingly, the circumferential
surface part can be provided in a state in which a plurality of
functional parts are provided. However, the circumferential surface
part 7a may be formed only by an integrated component as the outer
barrel 7.
[0290] In a case where the whole or a part of the circumferential
surface part 7a is curved, the rolling prevention protrusions 2f
and 2f are useful.
[0291] The adaptor 3 which is attached to the imaging device 2
transmitting an image data to the external display device 4, and
allows the imaging device 2 to be attachable to and detachable from
the display device 4, includes sliders (23 and 31) which are
slidable with respect to the outer barrel 7 of the imaging device
2; the first attached body 38 connected to the sliders (23 and 31);
the second attached body 43 which can change its gap with the first
attached body 38; and biasing members (first and second biasing
springs 30 and 37) which bias the first attached body 38 and the
second attached body 43 in a direction in which a gap therebetween
becomes narrowed. The display device 4 is grasped by the first
attached body 38 and the second attached body 43.
[0292] If the adaptor 3 is attached to the imaging device 2, the
imaging device 2 can be attached to the external display device 4
so as to be used.
[0293] When the imaging unit is viewed as a whole, the first
attached body 38 and the second attached body 43 are disposed at
the rear surface side thereof, and thus a structure of being
attached to a display device on the rear surface side of the
imaging unit is realized.
[0294] The imaging device 2 includes the first and second coupling
parts 12 and 12 which can be coupled to the adaptor 3 which is an
installation device; the first and second coupling parts 12 and 12
are disposed at the rear surface part 7c of the outer barrel 7; and
the storage part (the battery mounting part 70) which stores a
battery is provided between the first coupling part 12 and the
second coupling part 12 in the rear surface part 7c of the outer
barrel 7.
[0295] Therefore, the battery mounting part 70 is provided by
effectively using the rear surface part in which the first and
second coupling parts 12 and 12 are provided, that is, the space of
the installation surface side with the adaptor 3. Particularly,
since the battery mounting part 70 is provided between the first
and second coupling parts 12 and 12, the battery mounting part 70
can be provided in a state in which installation of the adaptor 3
is not impeded.
[0296] The imaging device 2 and the adaptor 3 are coupled to each
other by relatively rotating the imaging device 2 main body and the
adaptor 3 via the first and second coupling parts 12 and 12.
Accordingly, the imaging device and the installation device can be
easily coupled to each other.
[0297] As described above, in the imaging unit 1 (51) and the
adaptor 3 or 3A, the first attached body 38 is connected to the
second slider 31 in which the number of biasing springs interposed
up to the base body 15 is the maximum; a gap between the first
attached body 38 and the second attached body 43 varies so as to be
attached to the display devices 4 having different sizes; and
spring forces of the biasing springs are reduced in an order from
the first attached body 38 side to the base body 15 side.
[0298] Therefore, when a gap between the first attached body 38 and
the second attached body 43 varies, a spring force hardly varies
regardless of an extension amount of the biasing spring, and a
variation in a biasing force in a direction of the first attached
body 38 being close to the second attached body 43 is small. Thus,
it is possible to ensure a state in which the adaptor 3 is stably
attached to the display device 4 regardless of a size of the
display device 4.
[0299] In addition, since a plurality of biasing springs are
connected in series to each other, a large extension amount of the
biasing spring can be secured in proportion thereto, and a
sufficient gap between the first attached body 38 and the second
attached body 43 can be secured so as to correspond to the display
devices 4 having different sizes.
[0300] Further, in the adaptor 3, the first slider 23 and the
second slider 31 are provided as a plurality of sliders; the first
biasing spring 30 and the second biasing spring 37 are provided as
a plurality of biasing springs; and a spring force of the first
biasing spring 30 is smaller than a spring force of the second
biasing spring 37.
[0301] Therefore, with the minimally necessary configuration, it is
possible to reduce a difference between spring forces based on a
gap between the first attached body 38 and the second attached body
43, and it is possible to reduce the number of components and
simplify mechanisms. Thus, it is possible to ensure a state in
which the adaptor 3 is stably attached to the display device 4
regardless of a size of the display device 4.
[0302] Furthermore, since the plurality of biasing springs are
arranged in a direction perpendicular to a sliding direction of the
slider, it is possible to miniaturize the adaptor 3 and 3A in the
sliding direction.
