Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to an automatic sheet paper supplying toilet seat.

(B) Prior Art Conventionally, as a device for setting sheet paper on a toilet seat in consideration of hygiene, there is a toilet seat cover supplying device described in Japanese Utility Model Application Publication No. 155399/1983.

The device is designed to have a size and shape that can cover the top surface of the toilet seat, and is capable of winding up or folding continuous sheet paper and storing it in a continuous manner. a sheet paper roll holder configured to feed out the sheet paper in a fixed manner, and a feed roller on the sheet paper feeding side of the sheet paper roll holder for sending a predetermined length of the sheet paper forward near the top surface of the toilet seat. The present invention is characterized in that it comprises a feed-out cutting section for the sheet paper and a cutting blade for cutting the rear end of the fed-out sheet paper of a predetermined length.

In such conventional devices, sheet paper feeding and cutting operations are performed by pressing an operation button to rotate a feeding roller or by raising and lowering a cutting cutter.

In addition, when using the toilet, the patient sits on a sheet of paper whose rear end has already been cut off.

(C) Problems to be Solved by the Invention However, such toilet seats were not provided with a means to deal with the case where the sheet paper from the sheet paper roll did not finish normally.

Therefore, if the feeding operation continues with the sheet paper stuck in the functional section, there is a problem in that the sheet paper will become further jammed in the functional section, making maintenance very troublesome. Moreover, in this case, the sheet paper is simply fed out into the functional section in vain and is not used for actual use, which is extremely uneconomical.

An object of the present invention is to provide an automatic sheet paper supply toilet seat that can solve the above problems.

(d) Means for Solving the Problems The present invention provides a sheet paper roll disposed behind the toilet seat body, and a sheet paper feeding mechanism for feeding the sheet paper from the sheet paper roll onto the top surface of the toilet seat body. , a position detection means that detects the detected parts provided at intervals on the sheet paper and generates a detection output, and a position detection means that controls the drive of the sheet paper feeding mechanism based on the output, and moves the sheet paper to a set length. The control unit is configured to turn off the sheet paper feeding mechanism if the position detection means does not generate a detection output for a set time after the sheet paper feeding starts. The present invention relates to a toilet seat that automatically supplies sheet paper.

(e) Actions and Effects With the configuration described above, the present invention has the following effects.

That is, in the present invention, in normal operation,
The position detection means detects the detected portion being transferred to the toilet seat main body as the sheet paper is fed out, generates a detection output, and stops the sheet paper feeding mechanism portion by the control device based on the output, Sheet paper can be fed out to a set length onto the toilet seat body.

In addition, if a paper problem such as a paper jam occurs in the functional unit, that is, if the position detection means does not generate a detection output for a set time or more in the control unit, it is determined that a paper problem such as a paper jam has occurred. Since the sheet paper feeding mechanism section is configured to be turned off, the sheet paper is not unnecessarily fed out many times when the sheet paper is jammed in the functional section, which is economical.

Next, the configurations of the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section D housed in the functional section casing 15 will be explained.

First, to explain the sheet paper feeding mechanism section C, as shown in FIGS. 3 to 5, a sheet paper feeding shaft 30 is rotatably mounted horizontally between the rear upper parts of the left and right side walls 18 and 19 of the casing body 16. A feeding roller 31 having approximately the same length but differing in diameter is integrally fixed to the feeding shaft 30.

As shown in FIG. 4, the feeding roller 31 is connected to a pressing roller 32 disposed above
The sheet paper P can be fed and fed onto the toilet seat main body 11 from a sheet paper roll storage section E, which will be described later, by pressing and clamping the drawn-out end of the sheet paper P in cooperation with the toilet seat main body 11.

Further, in FIGS. 4 and 5, reference numeral 33 denotes a suspension support that is U-shaped when viewed from the front and is composed of left and right swinging arms 34 and 35 and a connecting plate 36 that connects the lower ends of both arms 34 and 35. It is a frame, and the same suspension support frame 3
The upper ends of the left and right swing arms 34 and 35 of No. 3 are swingably attached to the sheet paper roll mounting walls 23 and 24 via cylindrical boss portions 37 and 38.

The press roller 32 described above is installed in a roller installation space formed between the lower end rear parts of the left and right swing arms 34 and 35 of the suspension support frame 33.

In addition, as shown in FIG.
A line L1 connecting 7, 38 and the presser roller 32 is a perpendicular line L2 extending downward from the cylindrical boss parts 37, 38.
Since the pressure roller 32 is inclined to
In the normal contact state, the feeding roller 3
By being pressed against 1, the sheet paper P is
It can be clamped with appropriate pressure for feeding.

Further, in FIGS. 5 and 6, reference numeral 40 is a rotary motor disposed in the compartment 23b, and the rotary motor 40 connects its output shaft to the sheet paper feeding shaft 30 through a speed reduction device 41. It is connected to the left end of.

And the left end of the sheet paper feeding shaft 30,
Transmission gears 42 and 43 are fixed to the left end of the roller mounting shaft 32a of the presser roller 32, respectively, and both transmission gears 42 and 43 can mesh with each other.

Therefore, when the sheet paper feeding shaft 30 is rotated by the rotary motor 40, the feeding roller 3
1 and the press roller 32 are also rotated together via the same transmission gears 42 and 43.
Sheet paper P is fed out from a sheet paper roll R in a sheet paper roll storage section E, which will be described later, and then passed through a sheet paper delivery path 8 formed between the inclined ceiling wall 22 of the casing body 16 and the lower surface of the hanging support frame 33. , and can be delivered onto the toilet seat body 11.

Further, as will be described later, the sheet paper P is clamped between the feed roller 31 and the press roller 32, but in this case, both rollers 31 and 32 are engaged with each other by transmission gears 42 and 43. , as long as the rotation motor 40 is in a stopped state,
Not only the feeding roller 31 but also the holding roller 3
2 can be reliably prevented from rotating, and loosening of the clamping force due to slipping of the pressing roller 32 can be reliably prevented.

Next, the configuration of the sheet paper cutting mechanism section D will be explained.

In this embodiment, as shown in FIGS. 4 and 5, the sheet paper cutting mechanism D is swingably mounted in a plate insertion space 22a provided at the front of the inclined ceiling wall 22 of the casing body 16. The movable plate 50 disposed, the swinging arm 34 of the suspension support frame 33 disposed above the movable plate 50,
35, and a swing plate 51 swingably installed between the lower end front portions of the swing plates 35 and 35.

First, to explain the configuration of the movable plate 50, as shown in FIGS. 4 and 5, the movable plate 50 is formed from a long and wide rectangular flat plate extending in the left-right direction, and has pivots at both ends. 5
2, 53 are provided protrudingly, and the same pivots 52, 53,
Left and right side walls 18 and 1 of the casing body 16, respectively.
It is rotatably supported on 9.

Moreover, 54 and 55 are biasing springs attached to the pivot shafts 52 and 53 in order to keep a guide roller 70, which will be described later, in constant contact with the disk cam 71.

Further, 56 is a sheet paper pressing piece made of an elastic material, which is provided at the rear of the upper surface 50a of the movable plate 50, and cooperates with a sheet paper pressing piece 64 of the swinging plate 51, which will be described later, to press the sheet paper
It is used to clamp.

When feeding out the sheet paper P onto the toilet seat main body 11, as shown in FIG. 8 can be formed.

Furthermore, as will be described later, when cutting the sheet paper P, the movable plate 50 is moved around the pivots 52 and 5.
3 to take the rotational positions shown in FIGS. 7-9. Furthermore, when the toilet seat is not in use, the movable plate 50 can be made to take the rotational position shown in FIG. 10.

Next, the configuration of the swing plate 51 which cooperates with the movable plate 50 to cut the sheet paper P will be explained.

As shown in FIG. 4, the swing plate 51 has a thick sheet paper pressing portion 60 when viewed from the side.
and a thin sheet paper cut portion 61, and has a U-shaped cross section that opens downward.

The swinging plate 51 has pivots 62 and 63 protruding from both ends of the upper part of the sheet paper pressing part 60, and both pivots 62 and 63 are connected to the front lower ends of the left and right swinging arms 34 and 35 of the hanging support frame 33. It is pivoted so that it can rotate freely.

Furthermore, the swing plate 51 has a sheet paper pressing piece 64 made of an elastic material attached to the lower end of its sheet paper pressing part 60.
4 and the sheet paper pressing piece 5 of the movable plate 50
6 allows the sheet paper P to be clamped without causing slips.

Further, return springs 65 and 66 are attached to the pivots 62 and 63, respectively, and the springs 65 and 66 always urge the swing plate 51 to rotate counterclockwise in FIG. In cooperation with stoppers 67 and 68 protruding from the inner surfaces of the sheet paper roll mounting walls 23 and 24, the sheet paper cutting section 61 is moved to the standby position shown in FIG.
The swing plate 51 can be held in a position where it is retracted from the sheet paper delivery path 8.

Next, the movable plate 50 and the swing plate 5
Various types of drive mechanisms are conceivable for the sheet paper cutting mechanism D consisting of 1.
This embodiment is constructed as shown in FIGS. 4 to 6.

That is, the guide roller 70 is attached to the movable plate 50 at a lower portion thereof and at a position eccentric to the rear from the pivot shafts 52 and 53. The guide roller 70 is located below the guide roller 70.
A disc cam 71 is provided which rotatably contacts the guide roller 70 and moves the guide roller 70 up and down by rotation, and a rotating shaft 72 to which the disc cam 71 is fixed is
Both ends of the rectangular mounting plate 1 of the casing body 16
It is rotatably supported by a pair of bearing stands 73 erected on 7. Moreover, one side extension part of the rotating shaft 72 passes through the left side wall 18 and connects to a compartment 23 formed between the sheet paper roll mounting wall 23 and the outer wall 23a.
b, and the extended portion is connected to the deceleration device 74.
It is interlocked and connected to the rotation motor 75 via.

With this configuration, when the rotation motor 75 is driven, the rotation shaft 72 rotates, and the disc cam 71 that is integral with the rotation shaft 72 also rotates about the axis of the rotation shaft 72. Since the center of the disc cam 71 is eccentric from the axis of the rotating shaft 72, the circumferential surface of the disc cam 71 draws a cam locus of an irregularly shaped circle, and the guide roller has a circumferential surface that comes into contact with the same circumferential surface. 70 moves up and down, and by this up and down movement, the movable plate 50 can be swung around the pivots 52 and 53, and in conjunction with the swiveling of the movable plate 50, the swiveling plate 51 can also be swung. By moving, the sheet paper P can be effectively cut in the manner described below.

First, in FIG. 4, the sheet paper P is fed out onto the toilet seat main body 11 through the sheet paper feeding path 8 by the rotation of the feeding roller 31 and press roller 32 driven by the sheet paper feeding mechanism section C mentioned above. It can be done. In addition, in that case,
Cutting perforation 90 provided in sheet paper P
(See FIG. 3) is fed out so that it is positioned substantially directly below the cutting blade 61a of the sheet paper cutting section 61 of the swing plate 51.

Next, the rotary motor 75 is driven to rotate the disc cam 7.
1 clockwise, the guide roller 70
The movable plate 50 rotates counterclockwise around the pivots 52 and 53 via the pivot plate 50, and as shown in FIG. Clamp P. Then, the portion of the sheet paper P located between the clamp portion and the clamp portion in contact with the feeding roller 31 and the holding roller 32 is pressed and bent upward by the rear end of the movable plate 50, and tension is applied to the sheet paper P. Add.

As described above, the feeding roller 31 and the pressing roller 32 are engaged with each other through the transmission gears 42 and 43, and the movable plate 50 and the swinging plate 51 are connected to each other via the sheet paper pressing pieces 56 and 64. Since the sheet paper P is clamped, slips at the clamped portion can be reliably prevented.

Thereafter, when the disk cam 71 is further rotated clockwise, the movable plate 50 further rotates counterclockwise as shown in FIG. 8, while the movable plate 50 rotates the swing plate 51 clockwise. I will let you do it. Therefore, the cutting blade 61 provided at the tip of the sheet paper cutting section 61 of the swing plate 51
a further applies tension while pressing the sheet paper P downward.

Further, as shown in FIG. 9, if the disc cam 71 is rotated clockwise, the movable plate 50 is further rotated counterclockwise, and the swing plate 5
1 rotates clockwise, and by the same rotation, the cutting blade 61a of the sheet paper cutting section 61 of the swing plate 51 further presses the sheet paper P downward to apply tension, and as a result, the sheet paper P is , will be cut from the perforation 90.
Then, the sheet paper P after cutting is pressed by the pressing piece 5
6 and 64 continues.

When the user leaves the toilet seat main body 11 after sitting down and relieving himself, the seating detection means 96 (to be described later) detects the movement of the user leaving the toilet seat body 11, and when the detection signal is sent to the control unit F, the disc cam 71 rotates clockwise, and the movable plate 50 then rotates clockwise to release the clamp on the sheet paper P and assume the position shown in FIG.
It functions as a barrier to prevent the intrusion of sewage, and can effectively prevent splashed water from flowing into the sheet paper delivery path 8.

Note that since the sheet paper P is cut by applying tension and pressing force to the sheet paper P, the sheet paper cutting section 61 of the swing plate 51 or its cutting blade 61a should not be cut with a sharp metal or the like. It is not necessary to form it straight, but it can also be formed from rounded ceramics, corrosion-resistant and abrasion-resistant synthetic resin, or the like.

Therefore, even during long-term use, frequent replacement of the swing plate 51 due to corrosion or wear can be prevented, and maintenance can be improved.

Similarly, the movable plate 51 can also be made of corrosion-resistant and wear-resistant synthetic resin, ceramics, or the like.

Moreover, if the cutting blade 61a is formed into a chevron shape as shown in FIG. 5, cutting can be facilitated.

Next, the configuration of the sheet paper roll storage section E disposed on the casing body 16 including the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section D will be described.

In FIGS. 4 and 5, reference numerals 80 and 81 indicate support rods fitted into the boss portions 37 and 38 of the suspension support frame 33, which are equipped with springs 82 inside. Both ends of a hollow roll core 83 having a roll R attached to its outer peripheral surface are inserted and constructed in a detachable manner.

Further, 84 is a sheet paper roll protective cover disposed on the casing main body 16 in a state surrounding the sheet paper roll R, and its front lower end is provided at the sheet paper outlet 85 to prevent the swinging of the hanging support frame 33. It is removably engaged with and supported on a cover receiving plate 86 installed between the front lower ends of the arms 34 and 35, and the rear lower end is attached to the casing body 1.
It is engaged and supported by the upper end of an extended rear wall 87 extending above the rear wall 21 of 6.

In addition, the above sheet paper roll protective cover 8
Both ends of the sheet paper roll mounting wall 23 are engaged with fitting grooves 88 and 89 recessed along the inner edge of the sheet paper roll mounting wall 23, as shown in FIGS. 5 and 11.

With this configuration, when the sheet paper P is rewound, or when the movable plate 50 is
It is possible to prevent the suspension support frame 33 from swinging due to vibrations generated when it comes into contact with the suspension support frame 33.

In addition, in the unlikely event that the sheet paper P becomes clogged or tangled in the sheet paper feed path 8, etc., causing trouble, remove the sheet paper roll protection cover 84 as shown in FIG. By swinging the frame 33 forward, the entangled sheet paper P can be easily removed.

Next, the sheet paper P used in this example will be explained. As shown in FIGS. 4 and 5, the sheet paper P forms a part of the sheet paper roll R, and is used after being cut. It is something.

The reason why the sheet paper P is formed from the sheet paper roll R is that the sheet paper P for a large number of people can be stored compactly in the functional part 14 provided at the rear of the toilet seat main body 11.
This is to enable the toilet seat body 11 to be automatically and accurately extended onto the upper surface.

Further, as shown in FIGS. 3 and 12, the sheet paper P is provided with linear cutting perforations 90 in the width direction at regular intervals in the longitudinal direction or the feeding direction, and the sheet paper P is provided with straight cutting perforations 90 in the width direction. Then, the sheet paper P is cut.

In addition, sheet paper P has perforation 9 for cutting.
A cut-out perforation 91 with a shape that matches the inner shape of the toilet seat body 11 is provided in the center between An opening communicating with the interior of the toilet bowl 10 may be provided.

However, the cutout perforation 91 is not completely annular, and a non-perforated part 92 is formed between both ends of the rear part, so the cutout perforation 91 is not completely circular.
When 1 is cut out, the cut out central part will hang down inside the flush toilet bowl 10, and the lower end will be submerged in standing water.

In addition, the sheet paper P is not completely perforated, and the non-perforated part 92 and the perforated part 9 for cutting out
1 is provided because if the sheet paper P is perforated, it will not be stiff, and when feeding the sheet paper P onto the toilet seat main body 11, it will not bend and it will be almost impossible to form the sheet paper roll R. That's why. In other words, the sheet paper P provided with the cutout perforations 91 and the non-perforated portions 92 has sufficient stiffness and can be easily fed automatically and rolled.

Further, the perforations 91 for cutting out the sheet paper P can prevent the sheet paper P from getting caught in the feeding roller 31 and the pressing roller 32 during feeding and causing paper jams as much as possible.

Further, the perforations 91 for cutting out the sheet paper P can be made into perforations throughout the sheet paper P in a shape that matches the inside shape of the toilet seat body 11.
It is also possible to provide perforations here and there and make cuts elsewhere.

Furthermore, as shown in FIGS. 3 and 12, the sheet paper P is arranged at regular intervals in the longitudinal direction.
A position detection through hole 93 is provided between the non-perforated part 92 and the tip of the cutout perforation 91,
On the other hand, the casing body 16 corresponding to the through hole 93
A position detection sensor 94 consisting of a light emitting element and a light receiving element is provided at the front of the inclined ceiling wall 22 .

The position detection sensor 94 detects the through hole 93 when the sheet paper P is fed out a predetermined length from the sheet paper roll R, stops the operation of the sheet paper feeding mechanism section C, and accurately Sheet paper P can be supplied and positioned on the toilet seat body 11.

Note that instead of the through holes 93, desired colored marks may be applied to the sheet paper P, and furthermore, the attachment positions of the through holes 93, etc.
It can be placed not only at the center but also at any desired location.

Further, the above-mentioned feeding and positioning of the sheet paper P is performed by counting the number of rotations of the rotary motor 40 with a desired counter, without using the above-mentioned position detection sensor 94, and operating the control section F based on the counted value. You can also do it by

Further, in FIG. 1, reference numeral 96 is a seating detection means consisting of a reflective infrared sensor provided on the inner surface of the one side extension 25 of the casing body 16, and after the user is seated on the toilet seat body 11, When the user leaves the toilet seat main body 11 after a period of time (for example, 5 seconds) has elapsed, a detection signal is generated, the control unit F is activated, the rotation motor 75 is driven, and the clamp on the sheet paper P is released. At the same time, the movable plate 50 and the swing plate 51 can be moved from the position shown in FIG. 9 to the position shown in FIG. 10 so as to block the entry of dirty water into the sheet paper delivery path 8.

Note that this seating detection means 96 is
Depending on the usage environment, it is possible to integrate it into the automatic sheet paper supply toilet seat A or to separate it into a separate body.

Furthermore, in addition to the above-mentioned infrared sensor and the like, the seating detection means 96 can also operate the control section F by using a micro switch, a limit switch, etc., or by detecting the load at the time of seating with a load cell or the like.

In addition, in FIG. 1, reference numeral 97 indicates that when the toilet seat main body 11 is in a state where it cannot be seated (when the toilet seat main body 11 is in an upright position), the detection is removed from the toilet seat main body 11. It is an abnormal feeding prevention sensor for stopping the supply of sheet paper P by cutting off the power to the toilet seat body 11.
The toilet seat main body 11 is detected only when the toilet seat body 11 is in a seatable state, and the toilet seat main body 11 is made operable.

It should be noted that a micro switch, a limit switch, or the like may be used as the abnormal delivery prevention sensor 97 instead of a normal sensor.

Next, the configuration of the sheet paper feeding mechanism section C, the sheet paper cutting mechanism section D, and the control section F that controls the operations of various sensors and detection means will be explained.

As shown in FIG. 5, a control unit mounting plate 1
A control panel 101 for controlling the operation of the rotation motors 40, 75, etc. described above is attached to the control unit mounting plate 100, forming a control unit F. Note that the control panel 101
The transformer 102 is also integrally attached.

Next, the operation section G will be explained.As is most obvious from FIGS. 1 and 3, the operation section G
The upper surface of the one side extension part 25 of the casing body 16 is equipped with a push button 103 for sheet paper feeding, a power lamp 104 consisting of a light emitting diode, etc., and a warning function in the event of an abnormality such as a paper jam or paper replenishment. It is constructed by attaching a paper supply lamp 105, a paper trouble lamp 106, and the like.

Note that a buzzer or the like may be installed instead of the paper replenishment lamp 105 or the like.

Further, FIG. 13 shows the configuration of a control device that controls the operation of the automatic sheet paper supplying toilet seat A.

As shown in FIG. 13, the control unit F includes a microprocessor MPU and an input/output interface 1.
10, 111, and a memory M storing a sheet paper feeding/cutting order program to be described below.

The input interface 110 is interposed between the sheet paper feeding push button 103, position detection sensor means 94, seating detection means 96, etc. and the microprocessor MPU, and the output interface 111 is the microprocessor MPU. Setusa
It is interposed between the MPU and the sheet paper feeding mechanism section C, sheet paper cutting mechanism section D, etc.

Further, the control section F is equipped with a timer T1, and a position detection sensor 9 that operates simultaneously with the start of the sheet paper feeding operation by the sheet paper feeding motor 40.
When the position detection sensor 94, which operates at the same time as the predetermined time, does not detect the through hole 93 of the sheet paper P even after a predetermined time has elapsed, the output is sent to the control section F and an alarm buzzer is activated via the signal generator J. It is possible to notify that an abnormality has occurred in the sheet paper P by operating B _u or the paper trouble lamp 106.

Therefore, the user etc. can easily discover that the sheet paper P is jammed in the casing body 16 or that the sheet paper roll R is not stored, and can then quickly take appropriate countermeasures. .

Further, to explain other configurations in the illustrated embodiment, in FIG. 5, 120 and 1
21 are through holes provided in the outer wall 23a and the side wall 18, respectively, through which air flows in and the rotation motors 40,
75 can be cooled.

Hereinafter, the operation of the automatic sheet paper supplying toilet seat A having the above configuration will be explained with reference to the flowcharts shown in FIGS. 14A to 14B.

In the de-energized state, the movable plate 50 in the casing body 16 closes the sheet paper outlet 85 at one end, as shown in FIG. 8 is prevented from invading.

To use the flush toilet 10 in this state, as shown in FIG. 5, when the power switch S provided on the back surface of the casing body 16 is turned on (150), the power lamp 104 lights up (151).

Next, push button 10 for sheet paper feeding
When 3 is pressed (152), the rotation motor 7 of the sheet paper cutting mechanism section D is activated by the drive signal from the control section F.
5 and the rotation motor 4 of the sheet paper feeding mechanism section C.
0 operates sequentially. Then, the movable plate 50 is rotated counterclockwise by the clockwise rotation of the disc cam 71 driven by the rotation motor 75, and the first
The attitude shown in Fig. 0 will be changed to the attitude shown in Fig. 4. That is, a sheet paper delivery path 8 communicating with the sheet paper delivery port 85 is formed on the movable plate 50 (157).

Thereafter, the rotation motor 40 is driven to feed out the sheet paper P from the sheet paper roll R (158).

However, the sheet paper roll protective cover 84
is not installed on the casing body 16, the cover safety switch (not shown) is turned OFF.
Therefore, even if the sheet paper feeding push button 103 is pressed (152), no drive signal is sent from the control unit F to the rotation motor 40 under the control of the control unit F ( 153), the safety of operation can be ensured.

Furthermore, even if the user is sitting on the toilet seat main body 11 with the sheet paper P not being fed out, it is not preferable for the user to pay out the sheet paper P onto the toilet seat main body 11. The controller F is activated to prevent the control unit F from sending a drive signal to the rotation motor 40 (154).

Further, since it is not preferable to feed out the sheet paper P onto the toilet seat body 11 when the toilet seat body 11 is standing, the abnormal feeding prevention sensor 97 detects that the toilet seat body 11 is in the upright state, and the control unit F The drive signal is not sent to the rotation motor 40 (155).

Furthermore, even when the position detection sensor 94 that also serves as paper detection located inside the casing body 16 detects that the sheet paper P is present in the sheet paper delivery path 8 inside the functional unit casing 15, the sheet paper P For feeding, function part casing 15
Since this would cause the sheet paper P to get entangled in the rotation motor 40, the detection output is used to prevent the control unit F from sending a drive signal to the rotation motor 40 (156).

If there is no abnormality, as described above, the drive signal from the control unit F is sent to the rotation motor 40.
The rotation motor 40 is driven (158), and the sheet paper P is fed out from the sheet paper roll R.

Further, the timer circuit T2 (FIG. 13) is activated when the rotation motor 40 starts to be driven (159). Then, the sheet paper P is fed onto the toilet seat main body 11, and then the position detection sensor 94 detects the sheet paper P normally, that is, within the set time t1, and the sheet paper P is fed out within the set feed time t2. When detecting the through hole 93 provided in (159cY),
The rotary motor 40 stops with the set length of sheet paper P being fed out onto the toilet seat body 11 (160). At this point, sheet paper P
The cutting perforation 90 located at the rear end is located approximately directly below the sheet paper cutting blade 61a of the swing plate 51.

However, if there is an abnormality in the detection of the position detection sensor 94, that is, if the position detection sensor 94 does not detect the sheet paper P within the set feeding time t1 (159aN), the sheet paper feeding rotation motor 40 At the same time, the paper trouble lamp 106 is turned on (161).

Furthermore, even if the sheet paper P is detected within the set time t1, if the position detection sensor 94 detects the through hole 93 earlier than the next set feeding time t2 (counted from the start of driving the rotation motor 40), (159bY), the rotation motor 40 is similarly turned off, and the paper supply lamp 105 is turned on (162).

Further, if the through hole 93 is not detected within the set feeding time t2 (159 cN), the rotary motor 40 is turned off and the paper trouble lamp 106 is turned on (163).

Then, the rotation motor 75 is restarted by a drive signal from the control unit F, and as shown in FIGS. 7 and 8, the sheet paper P is clamped between the sheet paper pressing pieces 56 and 64 and fed out. When the roller 31 and the presser roller 32 are also clamped, and then the rotary motor 75 continues to be driven by continuous drive signals from the control unit F, the portion of the sheet paper P located between both clamped portions is moved in the feeding direction. Tension will be added (164).

Further, when the rotation motor 75 is driven by a drive signal from the control section F, the sheet paper cutting blade 61a of the sheet paper cutting section 61 of the swing plate 51 cuts the sheet paper P, as shown in FIG.
The sheet paper P is pressed along the cutting perforation 90, and the sheet paper P is reliably broken, ie, cut, by the pressing force and the tension in the feeding direction (165).

Thus, the rear end of the cut sheet paper P is securely clamped by the sheet paper pressing pieces 56 and 64 (165).

Thereafter, when the user sits on the toilet seat main body 11 (169), the seating detection means 96 detects that the user is seated (170), and based on the detection output, the control unit F then presses the sheet paper feeding push button 103. However, as long as the seating detection means 96 detects
Control is performed so as not to send a drive signal to the rotation motor 40 (171).

Therefore, even if the user presses the sheet paper feeding push button 103 by mistake or mischievously while seated, the sheet paper P will not be fed out, thereby preventing accidents such as entanglement of the sheet paper P within the casing body 16. can be reliably prevented.

Then, when the user leaves the toilet seat main body 11 after using the toilet (172), the seating detection means 96 is turned off (173), and based on the OFF signal, the control section sends a drive signal to the rotation motor 75 again. is sent to rotate the rotary motor 75. With this, the movable plate 5
0 and the swing plate 51 will assume the state shown in FIG.

That is, while the clamp of the sheet paper P is released, the movable plate 50 is set in the casing body 16 in a position that can reliably prevent dirty water from entering the sheet paper delivery path 8 through the sheet paper delivery port 85. can take (174)
(175).

Thereafter, the cleaning device is driven to clean the inside of the flush toilet bowl 10, and the force of the flushing water entrains the cut-off portion of the sheet paper P along with the flushing water and dirt and allows it to flow out.

In addition, in the above step, the movable plate 5
After the sheet paper P is cut and held (165) by the cooperation of the 0 and the swing plate 51,
If someone forcibly pulls out the sheet paper P (166) before sitting down (169), or the sheet paper P fed out onto the toilet seat body 11 is wet, the sheet paper should be fed out to remove it. If the push button 103 is held down for approximately 5 seconds (167), and if for some reason the user does not sit on the toilet seat body 11 within the predetermined time (168), the respective reset means will be activated. Then,
Regardless of the seating detection means 96, the sheet paper P
In order to discard the movable plate 50 as unused, the control unit F sends a drive signal to the rotation motor 75, and the movable plate 50
Then, the swing plate 51 is caused to assume the state shown in FIG. 10, and the clamp of the sheet paper P can be released and the sheet paper outlet 85 can be closed (174) (175).

With the configuration and operation described above, this embodiment has the following effects.

In this embodiment, if a paper trouble such as a paper jam occurs in the functional unit, that is, the control unit F
If the position detection means does not generate a detection output for a set time or more, it is determined that a paper problem such as a paper jam has occurred, and the sheet paper feeding mechanism section C is
In addition to turning it off, the signal generator J is configured to generate an abnormality signal, so paper problems such as paper jams and no paper can be quickly detected, and paper jams and sheets with entangled paper can be detected quickly. Appropriate measures such as promptly discarding the paper P and replenishing the sheet paper roll R can be taken, resulting in improved usability.
