FIELD OF THE INVENTION
[0002] The present invention relates to a rolled paper feeding
device in which a paper is fed out from a rolled paper by rotating
the rolled paper. More specifically, the present invention relates
to a rolled paper feeding device which is suitable to feed thin
paper such as toilet paper and paper towels.
BACKGROUND OF THE INVENTION
[0003] One of the conventional rolled paper feeding devices
includes a drive roller mounted on a holder that holds a roll of
toilet paper. The roll of toilet paper is rotated by the drive
roller to feed the paper outside (see Japanese Registered Utility
Model No. 3,024,537).
[0004] Another conventional rolled paper feeding device is
constructed such that the toilet paper drawn out from a roll of
toilet paper that is sandwiched between a pair of rollers and the
pair of rollers are rotated to draw out and feed the toilet paper
outside (see Japanese Patent Publication No. Hei 6-59268).
[0005] In the rolled paper feeding device described above, the roll
of toilet paper is held on the holder provided with the drive
roller, the roll of toilet paper comes into contact with the drive
roller by the weight of the roll of toilet paper. However, since
the weight of the roll of toilet paper is light, the contact
pressure is inadequate and thus it is difficult to obtain a strong
feeding force. Further, since the weight of the roll of toilet
paper varies with the use of the toilet paper, the feeding force
also varies. Especially, when the roll of toilet paper is reduced
and its weight becomes light, the drive roller can easily become
idle. In order to prevent the drive roller from becoming idle, a
weight or a spring may be arranged to apply a pressure to the drive
roller from the roll of toilet paper side but this may increase
component parts.
[0006] In the rolled paper feeding device, where the toilet paper
drawn out from the roll of toilet paper is sandwiched between a
pair of rollers to feed the toilet paper outside. Here, the number
of parts increases for the rolled paper device because a pair of
rollers are required. Moreover, at the time of setting up the roll
of toilet paper, the leading edge of the toilet paper has to be
inserted between the pair of rollers in order to operate. When an
automatic setting device for the leading edge of the toilet paper
is provided, the number of parts also increases.
[0007] In addition, when electric power is not supplied due to
battery shortage or power failure, it is difficult to draw out the
toilet paper because the pair of rollers has to be rotated
manually. Further, the rolled paper very easily torn. In order to
prevent this problem, a clutch is required in the pair of rollers.
However, in this case, the number of parts increases and the
mechanism becomes more complicated.
[0008] Moreover, the entire mechanism becomes larger and thus feels
unnatural when the large mechanism is installed in a restroom and
thus the design is not preferable. Further, the setting method for
the roll of toilet paper will be different from that of the
currently used manual rolled paper holder and thus requires more
effort.
[0009] These rolled paper feeding devices are provided with a
supply switch for feeding the toilet paper. When the supply switch
is turned on, a timer is operated to feed toilet paper to the
prescribed length. In order to adjust the feeding length of the
toilet paper, the setting time of the timer is changed, for
example, by rotating an adjustment knob.
[0010] However, in the rolled paper feeding device described above,
the setting time of the timer has to be adjusted when a user tries
to change the feeding length and thus fine adjustment is difficult.
Therefore, operability is not satisfactory.
[0011] Further, for example, it is conceivable that the rolled
paper feeding device is provided with a first switch for a long
feeding length, a second switch for a short feeding length and a
third switch for a continuous feeding. However, in this case, the
number of switches and the cost of the device increases. Also, the
size of each switch becomes small and thus the degree of freedom
for design decreases or operability is reduced.
[0012] In the rolled paper feeding device, the drive roller and a
motor are connected to each other through a gear train or a belt.
However, when the motor and the roller are connected through the
gear train or the belt and the motor stops because of a battery
shortage it is difficult to draw out the paper manually from the
rolled paper. This is because the detent torque of the motor exists
due to a motor stoppage, which gives a load on the roller to cause
it to be difficult to rotate. Alternatively, the paper may be torn
on the way even when it is drawn out, or a large amount of force is
required to draw out the paper and thus operability is not
satisfactory. In addition, since an overload is applied to the
roller, the durability performance is reduced.
[0013] Further, static electricity may flow through the rolled
paper device for various reasons. For example, static electricity
is charged on a user by friction of the user's clothes, by friction
between the user and a toilet seat cover, by an ion in the
atmosphere, by touching the rolled paper charged with electricity
or the like. The static electricity may flow to a control circuit
when the charged user touches the operation switches.
Alternatively, static electricity is generated by friction between
the rolled paper and a holder body or a cover part made by resin
for the rolled paper, which may cause the static electricity to
flow near the control circuit.
[0014] The rolled paper feeding device described above is not
provided with a device for protecting the control circuit from
static electricity. Therefore, when static electricity from a user
or a rolled paper flows to the control circuit, the control circuit
may be affected to cause an erroneous operation, a stoppage of
operation, the runaway or the destruction of the circuit.
SUMMARY OF THE INVENTION
[0015] In view of the problems described above, it is an object and
advantage of the present invention to provide a rolled paper
feeding device which is capable of obtaining a high feeding force
for the rolled paper without increasing the number of parts,
simplifying the setting of the rolled paper, and easily drawing out
the paper from the rolled paper manually at the time the motor
stops.
[0016] Further, it is another object and advantage of the present
invention to provide a rolled paper feeding device which has a good
operability of feeding the paper while restricting the number of
switches.
[0017] Further, it is another object and advantage of the present
invention to provide a rolled paper feeding device which is capable
of easily drawing out the paper manually from the rolled paper.
[0018] Further, it is another object and advantage of the present
invention to provide a rolled paper feeding device which is capable
of preventing an erroneous operation or the like due to static
electricity.
[0019] In order to achieve the above object and advantage,
according to an embodiment of the present invention, there is
provided a rolled paper feeding device including a holder body
which rotatably supports a rolled paper, a cover part one end of
which is rotatably supported in a contacting and separating
direction with respect to the rolled paper and the other end of
which abuts with the rolled paper, a feed roller which is provided
in the cover part for feeding a paper of the rolled paper and a
drive part which is provided in the cover part for rotationally
driving the feed roller. The feed roller is arranged on the other
end side with respect to a center of the rolled paper.
[0020] According to the embodiment of the present invention, the
cover part is provided with at least the feed roller and the drive
part comes into contact with the rolled paper from an upper side
and makes the feed roller press the rolled paper in an appropriate
force by the weight of the cover part. Therefore, the contact
pressure is increased more compared to the conventional mechanism
that the rolled paper comes into contact with the feed roller by
the weight of the rolled paper. Consequently, the idle rotation of
the feed roller is prevented and the feeding force for the rolled
paper can be increased.
[0021] Further, since the feed roller is arranged on the other end
side with respect to the center of the rolled paper, the feed
roller comes into contact with the rolled paper all the time even
when the remainder of the rolled paper is less and thus an
appropriate pad pressure can be obtained. Therefore, the feeding of
the paper of the rolled paper can be assured regardless of the
remaining quantity of the rolled paper.
[0022] In addition, the lid portion of a currently used manual
rolled paper holder can be replaced by the cover part of the rolled
paper feeding device in the embodiment of the present invention.
Therefore, the setting method of the rolled paper is the same as
that in the conventional holder and operability can be maintained.
Moreover, other component parts except the lid portion of the
currently used manual rolled paper holder can be used.
[0023] Further, according to the embodiment of the present
invention, only the cover part of the rolled paper feeding device
is made larger in comparison with the currently used manual rolled
paper holder and thus a simple and compact design can be
attained.
[0024] The rolled paper feeding device in accordance with an
embodiment of the present invention may be constructed such that an
electric power source for supplying electricity to the drive part
can be housed in the cover part. According to the construction
described above, since the cover part becomes sufficiently heavier
and thus the pad pressure on the rolled paper increases so that the
feeding of the rolled paper is assured.
[0025] In the rolled paper feeding device in accordance with an
embodiment of the present invention, the drive part may include a
motor and a speed reducing mechanism for transmitting a rotation
torque of the motor to the feed roller. In this case, the motor
rotates the feed roller through the speed reducing mechanism.
[0026] As described above, since the speed reducing mechanism is
utilized, the motor can be rotated at its maximum efficiency and
thus consumption current is restrained and the service life of the
power source (cell) can be extended.
[0027] In the rolled paper feeding device in an embodiment of the
present invention, a cutter is provided on the other end of the
cover part for cutting the paper of the rolled paper being fed out.
Therefore, the paper of the rolled paper can be easily cut by using
the cutter.
[0028] In the rolled paper feeding device in accordance with an
embodiment of the present invention, the cover part houses a feed
roller for feeding the paper of the rolled paper and a drive part
for rotationally driving the feed roller. The feed roller is
arranged on the other end side with respect to the center of the
rolled paper. The drive part may be constructed to include a drive
motor, a speed reducing mechanism for transmitting the rotation of
the drive motor to the feed roller, and an one way clutch for
transmitting the rotation of the drive motor to the feed
roller.
[0029] Therefore, since the one way clutch is provided in the drive
part for transmitting the rotation of the drive motor to the feed
roller, the rotation of the drive motor is transmitted to the feed
roller through the speed reducing mechanism and the one way clutch.
However, at the time of stopping of the drive motor, the rotation
applied to the one way clutch is changed into the opposite
direction and thus the clutch is operated. In other words, since
the one way clutch is provided, when the paper of the rolled paper
is drawn out, the one way clutch is operated so as to cut the
connection between the feed roller and the drive motor and thus the
rotation of the feed roller is not transmitted to the drive motor.
Therefore, the detent torque occurred by the stopping of the drive
motor does not affect the manual operation of drawing out the paper
of the rolled paper. Accordingly, the paper of the rolled paper can
be easily drawn out with minimal effort on the part of the user
without being torn.
[0030] In the rolled paper feeding device in accordance with an
embodiment of the present invention, the cover part houses a feed
roller for feeding the paper of the rolled paper and a drive part
for rotationally driving the feed roller. The feed roller is
arranged on the other end side with respect to the center of the
rolled paper. The cover part also includes a control part for
controlling the drive part and a static electricity eliminating
member disposed in the vicinity of the control part.
[0031] According to the embodiment described above, since the
static electricity eliminating member is disposed in the vicinity
of the control part, the static electricity applied to the control
part is eliminated and erroneous operations can be prevented.
[0032] In the rolled paper feeding device in accordance with an
embodiment of the present invention, the static electricity
eliminating member includes a first static electricity eliminating
member for preventing electrostatic charging of static electricity
from an operator and a second static electricity eliminating member
for preventing electrostatic charging of static electricity from
the rolled paper. Therefore, adverse effects due to the static
electricity from an operator and the static electricity from the
rolled paper can be eliminated.
[0033] Further, in order to achieve the above object and advantage,
according to an embodiment of the present invention, there is
provided a rolled paper feeding device including a holder body
which rotatably supports a rolled paper, a cover part one end of
which is rotatably supported in a contacting and separating
direction with respect to the rolled paper and the other end of
which abuts with the rolled paper, a feed roller for feeding a
paper of the rolled paper, a drive part for rotationally driving
the feed roller, a control part for controlling the drive part, and
a power source for supplying electricity to the drive part and the
control part. The control part includes at least a first and a
second switches, a timer for setting an operating time of an
operation which is executed on the basis of the "on" of the first
switch or the second switch, an AND gate which operates when both
the first and the second switches are turned on, and a control
circuit for controlling the drive part based on an output signal
from the timer or the AND gate. The control part is constructed
such that, when either of the first switch and the second switch is
turned on, the paper of the rolled paper is fed out with a
predetermined length corresponding to the first or the second
switch being turned "on", and when both the first switch and the
second switch are turned on, the paper of the rolled paper is fed
out with a length which is different from the predetermined
length.
[0034] Therefore, when both the first and the second switches are
turned on, the signal is inputted into the AND gate and the timer
is reset, and thus another feeding length can be set which is other
than the long feeding length and the short feeding length in the
case that either of the first and the second switches are turned
on. Accordingly, a user can obtain the desired length of paper from
the rolled paper. In addition, since the number of switches are
reduced, the cost reduction can be attained or the respective
switches are formed larger to enhance their operability.
[0035] Other features and advantages of the invention will be
apparent from the following detailed description, taken in
conjunction with the accompanying drawings that illustrate, by way
of example, various features of embodiments of the invention.

[0052] The feed rollers 7 are made of rubber in the embodiment of
the present invention and arranged at two positions in a coaxial
manner. The shaft 9 of the feed rollers 7 is rotatably supported by
grooves 10 formed on the case of the cover part 6. As shown in FIG.
6, the setting position of the feed roller 7 is set to be within
the range of "X" which is farther than the upper end (point "AA")
in the minimum diameter of the rolled paper 2 from the rotational
center 11 of the cover part 6 and which is nearer than the end
portion (point "BB") on the other end part 5 side in the minimum
diameter of the rolled paper 2 from the rotational center of the
cover part 6. As a result, the feed roller 7 can consistantly come
into contact with the rolled paper 2 regardless of the diameter of
the rolled paper 2. Moreover, the feeding force can be made uniform
because the feed roller 7 comes into contact with the rolled paper
2 with a uniform pressure.
[0053] The feed roller 7 is not limited to a roller made of rubber.
For example, it may be preferable to use a ceramic roller or a
recessed and protruded metal roller or the like as the feed roller
7, which can feed the paper of the rolled paper 2.
[0054] The power source 12 supplies electricity to the drive part 8
is housed in the cover part 6. In the embodiment of the present
invention, dry cells are used as the power source 12. Therefore,
since the cover part 6 becomes sufficiently heavy, the pad pressure
to the rolled paper 2 increases and thus the paper of the rolled
paper 2 can be surely supplied. A battery box 30 for storing the
power source 12 is formed in the cover part 6.
[0055] The drive part 8 includes the motor 13 and the speed
reducing mechanism 14 transmitting the rotating torque of the motor
13 to the feed roller 7. Multiple step deceleration gears are used
as the speed reducing mechanism 14. The speed reducing mechanism 14
is constructed such that the pinion 15 of the motor 13 is connected
to the pinion 16 fixed on the feed roller 7 through a gear train.
The notational symbol 20 in the drawing is a base plate for
supporting the gear train.
[0056] The notational symbol 15' shown in FIG. 4 is the same member
as the pinion 15 that is shown to easily understand the
relationship between the pinion 15 and the one way clutch 17.
[0057] The one way clutch 17 is used in the gear train as shown in
FIG. 4. The one way clutch 17 includes a ratchet 31 and a ratchet
gear 32 as shown in FIG. 8. The ratchet 31 and the ratchet gear 32
are arranged on a shaft 100 that is fixed on the cover part 6 in a
freely rotatable manner. As shown in FIG. 4, an output gear 173 is
integrally formed with the ratchet 31 and the rotation in a
predetermined direction is transmitted to the speed reducing
mechanism 14.
[0058] As shown in FIGS. 4 and 8, the ratchet 31 is formed with a
plurality of elastic arm parts 31a (three pieces in this
embodiment) and an engaging tooth part 31b at a front end of the
respective elastic arm parts 31a. The ratchet gear 32 is formed
with an engagement part 32a having recessed parts 32b each of which
is capable of elastically engaging with the engaging tooth part
31b. Therefore, when the rotation of the motor 13 is transmitted to
the feed roller 7, the rotation of the motor 13 is transmitted to
the ratchet gear 32 through the pinion 15 and further, the rotation
is transmitted to the engaging tooth parts 31b of the ratchet 31,
which is engaged with the recessed parts 32b of the engagement part
32a of the ratchet gear 32. Then, the rotation of the ratchet 31 is
transmitted to the output gear 173 and rotatably transmitted to the
speed reducing mechanism 14.
[0059] On the other hand, when the paper of the rolled paper 2 is
manually drawn out by rotating the feed roller 7 at the time the
motor 13 stops, the respective engaging tooth parts 31b disengage
from the respective recessed parts 32b by the elastic operation of
the elastic arm part 31a. Therefore, the rotation of the feed
roller 7 is not transmitted on the ratchet gear 32 side. In other
words, since the rotation of the feed roller 7 is not transmitted
to the motor 13, the detent torque of the motor 13 does not affect
the rotation of the feed roller 7 and thus the feed roller 7 can be
easily rotated. As a result, even when the power source is not
turned on, the paper of the rolled paper 2 can be easily drawn out
manually.
[0060] In the embodiment of the present invention, as shown in FIG.
4, the one way clutch 17 is disposed at the nearest position to the
motor 13 in the gear train from the motor 13 to the feed roller 7.
Therefore, at the time of a manual operation, the rotational speed
is accelerated from the feed roller 7 to the one way clutch 17 and
thus a large torque is applied to the one way clutch 17. However,
at the time of being driven by the motor 13, the force applied to
the one way clutch 17 can be made small and thus the one way clutch
17 of small proof stress can be employed.
[0061] In addition, as shown in FIG. 3, the gear train of the speed
reducing mechanism 14 is arranged in the horizontal direction and
thus the cover part 6 can be prevented from becoming large in the
height direction.
[0062] A cutter 18 for cutting the paper fed from the rolled paper
2 is fixed on the other end part 5 of the cover part 6. The cutter
18 is made of rubber. The paper of the rolled paper 2 can be easily
cut by using the cutter 18.
[0063] In addition, the cover part 6 houses the control part 19 for
controlling the drive part 8. The control part 19 includes, as
shown in FIG. 5, at least two switches, that is, a first switch 21
and a second switch 22, a first timer circuit 23 as a timer for
setting the operating time of an operation executed by turning on
the first switch 21, a second timer circuit 24 as a timer for
setting the operating time of an operation executed by turning on
the second switch 22, an AND gate 25 which generates an output
signal when both the first and the second switches 21 and 22 are
turned on, and a control circuit 26 for controlling the drive motor
13 as the drive part 8 based on the output signals from the first
and the second timer circuits 23 and 24 and the AND gate 25.
[0064] When the first switch 21 is turned on, the paper of the
rolled paper 2 is fed out by a predetermined length. When the
second switch 22 is turned on, the paper of the rolled paper 2 is
fed out by another predetermined length that is different from the
length for the first switch 21, that is, shorter than that for the
first switch 21 in the embodiment of the present invention. When
both the first and the second switches 21 and 22 are turned on, the
paper of the rolled paper 2 is fed out by further another length
other than the lengths described above. In the embodiment of the
present invention, the paper of the rolled paper 2 is continuously
fed out while both the first switch 21 and the second switch 22 are
turned on. In addition, the control part 19 also includes a
constant voltage circuit 27 for controlling the voltage of the
power source 12.
[0065] The cover part 6 is provided with first static electricity
eliminating members 28 and a second static electricity eliminating
member 29 as shown in FIG. 3. The first static electricity
eliminating member 28 prevents the electrostatic charge of static
electricity by an operator from adversely affecting the control
circuit or the electrostatic charge from flowing into the ground
GND of the control circuit. The first static electricity
eliminating members 28 are respectively formed of a wire spring and
disposed on the side portions of the first switch 21 and the second
switch 22. The second static electricity eliminating member 29
prevents the electrostatic charge of static electricity generated
on the rolled paper 2 from adversely affecting the control circuit
or the electrostatic charge from flowing into the ground GND of the
control circuit. The second static electricity eliminating member
29 is formed of a wire spring that is arranged from the lower
portion of the cover part 6 toward the rolled paper 2. The static
electricity eliminating members 28 and 29 are grounded to the
ground GND of the control part 19 or the power source 12 by
directly connecting to the base plate. These static electricity
eliminating members 28 and 29 respectively act as a lightning
conductor for the static electricity from an operator and the
rolled paper 2 and thus the erroneous operation of the control
circuit 26 can be prevented.
[0066] A protection sheet 136 is disposed above the respective
switches 21 and 22 as shown in FIG. 9. The protection sheet 136 is
a resin film. A user depresses and deforms the protection sheet 136
downward (two-dot chain line in the drawing) to depress the
respective switches 21 and 22. The first static electricity
eliminating member 28 is formed a slightly higher than the
respective switches 21 and 22. Therefore, when the protection sheet
136 is depressed, the protection sheet 136 comes into contact with
the first static electricity eliminating member 28 without
impairing the sense of operating the switches. The static
electricity from the user flows to the first static electricity
eliminating member 28 whose electric resistance is small and thus
the first static electricity eliminating member 28 acts as the
lightning conductor for the static electricity from the operator.
Therefore, the first static electricity eliminating member 28
prevents the control part 19 from an erroneous operation by the
static electricity.
[0067] The second static electricity eliminating member 29 includes
a contact part 133 protruding toward the rolled paper 2 and a
connecting part 134 electrically connected to the ground GND of the
control part 19 as shown in FIG. 10. The contact part 133 protrudes
so as to touch, nearly touch or slightly apart from the rolled
paper 2. The contact part 133 is surrounded by a rib 135 formed on
the case of the cover part 6. Therefore, the contact part 133 is
prevented from engaging with the rolled paper 2 and being
transformed. The static electricity from the rolled paper 2 flows
to the second static electricity eliminating member 29 and the
second static electricity eliminating member 29 acts as the
lightning conductor for the static electricity from the rolled
paper 2. Therefore, the second static electricity eliminating
member 29 prevents the control part 19 from an erroneous operation
by static electricity.
[0068] An example of the operation of the rolled paper feeding
device 1 will be described below.
[0069] A rolled paper 2 is set on the holder body 3 and the cover
part 6 is placed on the rolled paper 2. A holder body used in the
conventional manual system can be utilized for the holder body 3
and, in this case, a conventional operability can be maintained as
is.
[0070] A user turns on, for example, the first switch 21. As a
result, the first timer circuit 23 is activated as shown in FIG. 5
and the motor 13 is driven by the prescribed time period (long mode
in FIG. 7). Alternatively, when a user turns on the second switch
22, the second timer circuit 24 is activated and the motor 13 is
driven by the prescribed time period shorter than that by the first
timer circuit 23 (short mode in FIG. 7). In both the long mode and
the short mode, the first timer circuit 23 and the second timer
circuit 24 are respectively turned on by the "on" switches 21 and
22 and the motor 13 is driven by the prescribed time even when
switches 21 and 22 are turned off.
[0071] When the user turns on both switches 21 and 22, a continuous
mode is obtained and the motor 13 is driven while they are
depressed. At this time, the user tries to depress both the
switches 21 and 22 at the same time but this is difficult to
achieve. Accordingly, one switch is depressed first and then the
other switch is depressed with a very short time difference in
between. Therefore, the control circuit starts operation with a
mode corresponding to the switch being depressed first. On the
other hand, the AND gate 25 outputs signals to the first timer
circuit 23 and the second timer circuit 24 by both switches 21 and
22 being turned on to clear the time period of executing operation
and thus the respective timer functions are stopped. In the
embodiment of the present invention, the mode corresponding to the
switch depressed first is reset and the continuous mode is
operated. Therefore, the erroneous operation is prevented. In the
continuous mode, the first timer circuit 23 and the second timer
circuit 24 are not operated and the motor 13 stops when either of
the switches 21 and 22 is turned off.
[0072] In the embodiment of the present invention, the first
switch, the second switch and both of the switches are respectively
used to be set in the long mode, the short mode and the continuous
mode. However, the present invention is not limited to these modes.
For example, the second switch may be used to set in the continuous
mode, or another mode other than the long, short and continuous
modes may be used.
[0073] The rotation of the motor 13 is transmitted to the feed
roller 7 through the one way clutch 17 and the speed reducing
mechanism 14. Since the weight of the cover part 6 is applied to
the feed rollers 7, the rolled paper 2 is rotated without slippage
by the pressure of the cover part 6 and the paper is surely fed
out.
[0074] When the rolled paper 2 is rotated, friction occurs between
the case of the holder body 3 and the rolled paper 2 or the cover
part 6 and the rolled paper 2 and thus results in static
electricity being charged. The static electricity flows to the
contact part 133 of the second static electricity eliminating
member 29. Therefore, the control part 19 is prevented from
erroneous operation by the static electricity.
[0075] When the count of the first timer circuit 23 or the second
timer circuit 24 ends up in the long mode or the short mode, or
alternatively, when the switch 21 or 22 is turned off in the
continuous mode, the motor 13 stops and thus the feeding of the
rolled paper 2 stops. A user holds the paper that is fed of the
rolled paper 2 and cuts with the cutter 18. Since the cover part 6
has a sufficient weight, the paper of the rolled paper 2 can be cut
even when the cover part 6 is not pressed by hand.
[0076] On the other hand, for example, when the power source 12 is
stopped due to battery shortage or power failure, or when the user
tries to manually draw out the paper of the rolled paper 2 a little
after the paper with the prescribed length is fed out or the user
tries to manually draw out the paper of the rolled paper 2 even
when the drive motor 13 stops, the paper of the rolled paper 2 can
be easily drawn out manually. This is because when the paper of the
rolled paper 2 is drawn downward by hand at the time the motor 13
stops the feed rollers 7 are rotated to operate the speed reducing
mechanism 14. In the speed reducing mechanism 14, the one way
clutch 17 rotates idly and the motor 13 is separated from the gear
train. Therefore, the paper of the rolled paper 2 can be drawn out
with a little force without being affected by the detent torque of
the motor 13.
[0077] According to the embodiment of the present invention, the
paper of the rolled paper 2 is continuously fed out when "on" is
selected on both switches 21 and 22. Therefore, the feeding length
of the paper can be arbitrarily adjusted and thus operability is
enhanced.
[0078] Further, since three operation modes can be performed with
two switches 21 and 22, the number of switches and thus the cost
can be kept low. Moreover, the size of the switches 21 and 22 can
be made larger by the reduced number of switches and thus
operability is improved.
[0079] Furthermore, according to the embodiment of the present
invention, the static electricity eliminating members 28 and 29 are
provided and thus the erroneous operation of the control circuit 26
can be prevented. Therefore, the shield for the static electricity
is not required and the consideration of the resistance to static
electricity in the control part 19 is not needed. Accordingly, the
complication of the rolled paper feeding device 1 can be
prevented.
[0080] In addition, the holder body 3 can utilize the holder is
used in the current manual system as is and thus the setting method
for the rolled paper 2 is not required to change in comparison with
the conventional method and operability can be maintained.
Moreover, a design that is familiar to the user can be adopted for
the currently used manual rolled paper holder. Also, only the cover
part is larger in comparison with the currently used manual rolled
paper holder and thus a simple and compact design can be attained.
Accordingly, for example, when used in a restroom, the sense of a
small and narrow space can be reduced.
[0081] The present invention has been described in detail by using
above-mentioned embodiments, but the present invention is not
limited to the embodiments described above and many modifications
can be made without departing from the present invention.
[0082] For example, in one of the embodiments of the present
invention, the one way clutch 17 is arranged on the nearest side of
the motor 13 in the gear train from the motor 13 to the feed roller
7. However, the position of the one way clutch 17 is not limited to
the above-mentioned example and the one way clutch 17 maybe
disposed at other positions in the gear train. For example, as
shown in FIG. 11, the one way clutch 17 can be disposed on the feed
roller 7 side.
[0083] In this case, the final gear 33 of the speed reducing
mechanism 14 is coupled with the ratchet wheel 32 through gears and
the ratchet 31 is formed with an output gear 173 in an integral
manner. The output gear 173 is connected with the feed rollers 7
through the gear 34. The notational symbol "35" in FIG. 11 is the
gear 34, which is shown for easily understanding the relation
between the one way clutch 17 and the feed rollers 7. The operation
of the one way clutch 17 is similar to the above-mentioned
embodiment and thus its description is discussed above.
[0084] According to the construction described above, the force
applied to the one way clutch 17 becomes larger when the motor 13
is driven. However, at the time of a manual operation, the paper of
the rolled paper 2 can be drawn out with a little force because
accelerated force is not applied to the one way clutch 17. The
differences between the one way clutch 17 being arranged on the
drive motor 13 side and the one way clutch 17 being arranged on the
feed roller 7 side are shown in Table 1. In an actual design, the
one way clutch 17 is disposed at an optimal position in
consideration of the parameters as shown in Table 1 and other
elements.

[0085] In the embodiment described above, the one way clutch 17 is
constructed by using the ratchet 31 and the ratchet gear 32. The
present invention is not limited to the embodiments described above
and various types of one way clutch mechanisms such as a coil
spring type, a needle bearing type and a ball bearing type,
regardless of known or novel, can be employed.
[0086] For example, in the case of the coil spring type, as shown
in FIGS. 12 and 13, the one way clutch includes an output gear
wheel 37 rotatably provided on a roller shaft 36 of the feed roller
7 and an operation spring 38 made of a coil spring which is
coaxially provided on the output gear wheel 37 and the roller shaft
36. The output gear wheel 37 is engaged with the final gear 33 of
the speed reducing mechanism 14. In the embodiment described above,
the winding direction of the operation spring 38 is set to be in
the counterclockwise direction (CCW) viewed from the right side in
FIG. 12.
[0087] The roller shaft 36 and the output gear wheel 37 are
respectively formed with cylindrical parts 39 and 40 for engaging
with the operation spring 38 to perform a clutch operation. The
diameters of the respective cylindrical parts 39 and 40 are set to
be slightly bigger than the inner diameter of the operation spring
38. A surface treatment is performed on the outer peripheral face
of the respective cylindrical parts 39 and 40 such that an
appropriate frictional force is generated with the operation spring
38.
[0088] When the motor 13 is driven and a torque is transmitted from
the speed reducing mechanism 14 to the output gear wheel 37, the
output gear wheel 37 rotates in the clockwise direction (CW) in the
drawing. Since the cylindrical part 40 of the output gear wheel 37
similarly rotates in the clockwise direction (CW), the operation
spring 38 is wound up tightly by the frictional force between the
cylindrical part 40 and the operation spring 38. The winding
diameter of the operation spring 38 becomes smaller when the
operation spring 38 is wound up and tightened. Therefore, friction
is generated between the operation spring 38 and the cylindrical
part 39 of the roller shaft 36 to cause the roller shaft 36 to
rotate.
[0089] On the other hand, when the user tries to draw out the paper
of the rolled paper 2 at the time the motor 13 stops, the roller
shaft 36 is rotated in the clockwise direction (CW) in the drawing.
The cylindrical part 39 of the roller shaft 36 rotates similarly in
the clockwise direction (CW) and the winding of the operation
spring 38 is loosened by the friction force between the cylindrical
part 39 and the operation spring 38. When the winding of the
operation spring 38 is loosened, the diameter of the winding of the
operation spring 38 becomes larger. Consequently, the friction
between the operation spring 38 and the cylindrical part 39 of the
roller shaft 36 is reduced and thus the output gear wheel 37 does
not rotate.
[0090] According to the coil spring type one way clutch, the
construction of one way clutch can be simplified due to its simple
mechanism. In addition, complicated molded parts are not required
and thus cost does not increase. Further, the operation spring 38
and the cylindrical parts 39 and 40 are preferably coated with
grease or the like to perform a fine adjustment.
[0091] In the embodiment described above, the power source 12 is
housed in the cover part 6, but the present invention is not
limited to this construction and an external power supply may be
used. For example, an external battery box or AC power supply can
be used. In addition, the failure due to battery shortage can be
eliminated by using the AC power supply. Also, the control part 19
is not limited to be housed in the cover part 6 but may be disposed
outside of the cover part 6. For example, the control part 19 may
be arranged on the side portion of a toilet seat and the switching
operation may be performed on the side portion of the toilet
seat.
[0092] In the embodiment described above, a gear train is used for
the speed reducing mechanism 14 but the present invention is not
limited to the gear train. Other speed reducing mechanisms or
decelerating mechanisms, for example, using a pulley and a belt may
be used. In addition, in the embodiment described above, the one
way clutch 17 is utilized but, if not necessary, the one way clutch
17 may be omitted. In this case, when the paper of the rolled paper
2 is to be manually drawn out, the cover part 6 is lifted and then
the paper can be easily drawn out.
[0093] In the embodiment described above, an appropriate pressure
is applied to the rolled paper 2 only by using the weight of the
cover part 6. However, when a pad pressure is insufficient for
adopting various types of commercial rolled papers whose winding
and tightening states are different from each other, a weight or a
spring may be preferably provided to increase the pad pressure. In
the embodiment described above, the rubber cutter 18 is provided.
However, the cutter 18 may be made of another material such as
metal and alternatively the cutter 18 may be omitted.
[0094] In the embodiment described above, the paper of the rolled
paper is continuously fed out when the "on" is selected on both
switches 21 and 22. However, the paper of the rolled paper may be
fed out with a predetermined length, that differs from the "on"
state of the first switch 21 or the "on" state of the second switch
22.
[0095] The switch to be used is not limited to a mechanical switch
such as a push switch. A non-contact type switch using the infrared
ray, a light screening sensor or the like may be used. A
non-contact switch is convenient and sanitary though expensive.
[0096] In the embodiment described above, only two switches 21 and
22 are used but the present invention is not limited to two
switches and three switches or more may be used. In this case,
another feeding length of the paper may be set by the "on" state of
two or more switches.
[0097] In the embodiment described above, a toilet paper is used as
the rolled paper 2 but the present invention is not limited to the
toilet paper and various kinds of rolled papers 2 such as a paper
towels can be used.
[0098] In the embodiment described above, the lowering of the
voltage may occur with the change of load according to the rolled
paper used or with the use of dry cells as the power source.
Therefore, the control circuit of the drive part may be constructed
so as to include only an on-off switching circuit or a combined
circuit of a switching circuit and a constant voltage circuit, a
switching circuit and a constant current circuit, a switching
circuit and an electronic governor circuit, a switch and another
control means, or the like in order to maintain the rotation of the
motor as the drive part at a constant speed depending on the
desired accuracy for feeding the paper of the rolled paper.
[0099] Alternatively, the control circuit of the drive part is
constructed so as to include only an on-off switching circuit and a
mechanical governor may be used on the drive part side.
[0100] In the embodiment described above, the static electricity
eliminating members 28 and 29 are made of a wire spring but the
static electricity eliminating members 28 and 29 may be made of a
metal strip or a brush for electrostatic discharging.
[0101] In the embodiment described above, the first static
electricity eliminating member 28 is disposed on the respective
side portions of switches 21 and 22. However, the present invention
is not limited to that embodiment. For example, both switches 21
and 22 are disposed in close proximity and only one piece of the
first static electricity eliminating member 28 is disposed between
the switches 21 and 22. Alternatively, the first static electricity
eliminating member 28 may be formed of a metal foil or a metal
deposition film provided on the face of the protection sheet
36.
[0102] In addition, in the embodiment described above, each of the
static electricity eliminating members 28 and 29 are connected to
the ground GND directly. However, the present invention is not
limited to the embodiment and each of the static electricity
eliminating members 28 and 29 are connected to the ground GND
through a capacitor, a coil, a resistor or the like. Furthermore,
in the embodiment described above, each of the static electricity
eliminating members 28 and 29 are directly connected to the circuit
board of the control part 19. However, the present invention is not
limited to the above-mentioned embodiment and the static
electricity eliminating members 28 and 29 may be connected through
a lead wire or a flexible printed circuit board.
[0103] As described above, in the rolled paper feeding device in
accordance with the embodiment of the present invention, the cover
part provided with at least the feed roller and the drive part
comes into contact with the rolled paper from the upper side and
makes the feed roller press the rolled paper with the weight of the
cover part. Therefore, the contact pressure can be increased more
than in the conventional case where the rolled paper comes into
contact with the feed roller with the weight of the rolled paper.
Consequently, the idle rotation of the feed roller is prevented and
the feeding force for the rolled paper can be increased.
[0104] Further, since the feed roller is arranged on the front end
side with respect to the center of the rolled paper, the feed
roller comes into contact with the rolled paper all the time even
when the remainder of the rolled paper becomes a small amount and
thus an appropriate pad pressure can be obtained. Therefore, the
feeding of the paper of the rolled paper can be assured regardless
of the remained amount of the rolled paper.
[0105] In addition, the cover portion of the currently used manual
rolled paper holder can be replaced by the cover part of the rolled
paper feeding device in the embodiment of the present invention.
Therefore, the setting method of the rolled paper is the same as
that in the conventional holder and operability can be maintained.
Moreover, other component parts except the cover portion of the
currently used manual rolled paper holder can be used. Therefore,
the design that is familiar to the user can be adopted for the
currently used manual rolled paper holder.
[0106] Further, only the cover part of the rolled paper feeding
device is required to be larger in comparison with the currently
used manual rolled paper holder and thus a simple and compact
design can be attained. Accordingly, for example, when used in a
restroom, the sense of small and narrow space can be reduced.
[0107] Further, in the rolled paper feeding device in accordance
with the embodiment of the present invention, the long, short and
another lengths can be set and thus a user can obtain the paper of
the rolled paper with the desired length selected. As a result,
operability can be improved.
[0108] Also, since the number of switches are reduced, the cost
reduction can be attained or the larger respective switches are
formed to enhance their operability.
[0109] Further, in the rolled paper feeding device in accordance
with the embodiment of the present invention, since the static
electricity eliminating member is disposed in the vicinity of the
control part, the static electricity applied to the control part is
eliminated and erroneous operations or the like can be prevented.
Therefore, the shield for the static electricity is not required
and the consideration of the resistance to static electricity in
the control part is not needed. Accordingly, the device is
prevented from becoming complicated.
[0110] While the description above refers to particular embodiments
of the present invention, it will be understood that many
modifications may be made without departing from the spirit
thereof. The accompanying claims are intended to cover such
modifications as would fall within the true scope and spirit of the
present invention.
[0111] The presently disclosed embodiments are therefore to be
considered in all respects as illustrative and not restrictive, the
scope of the invention being indicated by the appended claims,
rather than the foregoing description, and all changes which come
within the meaning and range of equivalency of the claims are
therefore intended to be embraced therein.
