(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.

(c) Problems to be solved by the invention However, the sheet paper that is rolled out onto the top surface of the toilet seat and cut into single sheets is unstable and easily resistant to slight winds, such as winds caused by clothing or movement of the human body. If you sit on the toilet seat through the sheet paper, the sheet paper may shift with the slightest movement of your body, or when you stand up from the toilet seat after using the toilet. They often got stuck in the buttocks, but no effective measures had been taken to prevent this.

(d) Means for Solving the Problems The present invention provides a sheet paper roll disposed behind the toilet seat body, a sheet paper dispensing mechanism unit that dispenses the sheet paper from the sheet paper roll onto the top surface of the toilet seat body, and a dispensing mechanism. A sheet paper clamp section that clamps the subsequent sheet paper, a sheet paper cutting mechanism section that cuts the sheet paper, and a control section that controls the sheet paper feeding mechanism section, the sheet paper clamp section, and the sheet paper cutting mechanism section. In addition, a seating detection means is connected to the control section, and the control section clamps the sheet paper after the sheet paper feeding/cutting operation, and after the seating detection means detects the seating due to the use of the toilet seat, the seating detection means ends. The present invention provides an automatic sheet paper supplying toilet seat characterized in that the sheet paper clamp section holds the sheet paper clamp until input to the control section.

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

That is, the sheet paper is fed out from the sheet paper roll disposed behind the top surface of the toilet seat body by the sheet paper feeding mechanism section, the sheet paper is clamped by the sheet paper clamp section, and the sheet paper is fed out by the sheet paper cutting mechanism section. The patient then cuts a piece of sheet paper and sits on it to relieve himself.

However, when sitting on the toilet seat, a seating signal from the seating detection means activates the sheet paper clamp section to clamp the cut sheet paper and hold the sheet paper on the top surface of the toilet seat body.
When you stand up from the toilet seat, the seating signal from the seating detection means is terminated and the clamp is released to prevent the sheet paper from shifting or falling off when you sit down, or to prevent it from hitting your buttocks when you stand up from the toilet seat after using the toilet. It is possible to reliably prevent clinging.

5 and the control section F will be housed therein.

Furthermore, sheet paper roll mounting walls 23, 2
4 and the outer walls 23a, 24a, as shown in FIGS. 3 and 4, have their front parts projecting forward from the front wall of the casing body 16 to form extensions 25, 26, and both extensions The proximal end side of the toilet seat body 11 is pivotally supported on the parts 25 and 26 by a pivot 13.

Next, the configurations of the sheet paper feeding mechanism section C, the sheet paper clamp 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 part C and the sheet paper clamp part C', as shown in FIGS. 30 is horizontally suspended so as to be freely rotatable, and feeding rollers 31 having approximately the same length but different diameters are 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 swinging arms 34 and 35 of No. 3 are connected to the sheet paper mounting wall 2 through cylindrical boss portions 37 and 38.
3 and 24 so as to be swingable. The above-mentioned pressing roller 32 is attached to the suspension support frame 3.
It 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 No. 3.

In addition, as shown in FIG.
The line L1 connecting 7, 38 and the presser roller 32 is
Perpendicular lines extending downward from the cylindrical boss parts 37 and 38
Since it is inclined with respect to L2, the press roller 32 is in pressure contact with the feeding roller 31 in the normal contact state, and the sheet paper P can be held between the sheet paper P with appropriate pressure for feeding. I can do it.

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. , 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 rotary motor 40 is in a stopped state, not only the rotation of the feed roller 31 but also the holding roller 32 can be reliably prevented, and loosening of the clamping force due to slipping of the holding roller 32, etc. can be reliably prevented. I can do it.

Next, the configurations of the sheet paper clamp section C' and the sheet paper cutting mechanism section D will be explained.

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

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 disc cam 71.

In this embodiment, the upper surface 50a of the movable plate 50
A sheet paper clamp section C' is constituted by a sheet paper pressing piece 56 made of an elastic material provided at the rear of the sheet paper pressing piece 56 and a sheet paper pressing piece 64 provided on the swing plate 51, which will be described later. Pieces 56 and 64 work together to form sheet paper P.
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 structure 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.

This 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 side of the left and right swinging arms 34 and 35 of the hanging support frame 33. It is rotatably supported at the lower end.

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
The sheet paper P can be clamped by the sheet paper clamp portion C' consisting of the sheet paper P without slipping.

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, various types of drive mechanisms are conceivable for the sheet paper clamp section C' and the sheet paper cutting mechanism section D, but in this embodiment, the fourth
It is constructed as shown in FIGS.

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 disposed in rotatable contact with 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 where the feeding roller 31 and the holding roller 32 come into contact 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 configured to hold a sheet consisting of sheet paper pressing pieces 54 and 64. Since the sheet paper P is clamped via the paper clamp portion C', slips at the clamp portion can be reliably prevented.

Thereafter, when the disc cam 71 is further rotated clockwise, the movable plate 50 further rotates counterclockwise as shown in FIG. It will be rotated. Therefore, the cutting blade 61a provided at the tip of the sheet paper cutting section 61 of the swing plate 51 presses the sheet paper P downward while further applying tension.

Further, as shown in FIG. 9, if the disk cam 71 is rotated clockwise, the movable plate 50 is further rotated counterclockwise, and the
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 using the toilet, the disc cam 71 further rotates clockwise, and the movable plate 50 rotates clockwise this time, releasing the clamp on the sheet paper P. By taking the position shown in FIG. 10, it is possible to effectively prevent splashed water from flowing into the sheet paper delivery path 8 during washing after using the toilet.

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 50 can also be made of corrosion-resistant and wear-resistant synthetic resin, ceramics, or the like.

Further, as shown in FIG. 5, the blade 61a can be formed into a chevron shape to facilitate cutting.

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. The sheet paper P is then 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 reason why the sheet paper P is not completely perforated is that the non-perforated part 92 and the cutout perforations 91 are provided. This is because the sheet paper roll R is almost impossible to form because it bends and tumbles when being fed to the sheet paper roll R. In other words, perforation 91 for cutting out
Sheet paper P with a non-perforated portion 92
has sufficient strength and can easily be used for both automatic feeding and roll processing.

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 position detection through hole 93 when the sheet paper P has been unwound for a predetermined length from the sheet paper roll R.
is detected, the operation of the sheet paper feeding mechanism section C is stopped, and the sheet paper P is accurately delivered to the toilet seat main body 1.
It can be supplied and positioned on 1.

In addition, the distance between the position detection through holes 93, 93 at the end of the sheet paper roll R is made shorter than the distance at other parts, and the distance between the through holes 9 of the position detection sensor 94 when the paper P is fed out is reduced.
3. By shortening the detection interval, the end of the roll R can be detected.

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 provided on the inner surface of the one side extension 25 of the casing body 16 and consisting of a reflective infrared sensor or the like. (for example, 5 seconds), when the user leaves the toilet seat body 11, a detection signal is generated, activates the control unit F, drives the rotation motor 75, and releases the clamp on the sheet paper P. 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 an infrared sensor or the like, the seating detection means 96 can also use a micro switch, a limit switch, or the like, or a load cell that detects the load when the passenger is seated.

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 (toilet seat main body 11 stands on its own), 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 clamp section C', the sheet paper cutting mechanism 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 board 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.

Next, the operation section G will be explained.As is most obvious from FIGS. 1 and 3, the operation section G
The casing body 16 has a sheet paper feeding button 103, a power lamp 104 consisting of a light emitting diode, etc. on the upper surface of the one side extension 25 of the casing body 16, and a warning function in the event of an abnormality such as a paper jam or paper replenishment. Paper supply lamp 105, paper trouble lamp 1
It is constructed by attaching 06 etc.

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.

In FIG. 13, 110 is an input interface interposed between the sheet paper feeding button 103, position detection sensor 94, seating detection means 96, etc. and the control unit F, and 111 is an input interface between the control unit F and the sheet paper This is an output interface interposed between the feeding mechanism section C, sheet paper cutting mechanism section D, etc.

A control sequence shown in the flowcharts of FIGS. 14A to 14B is programmed in the control section F, and in particular, when the sheet paper feeding button 103 is pressed during the program, the sheet paper feeding mechanism section After feeding the sheet paper P onto the top surface of the toilet seat body 11 at C and cutting the paper P at the sheet paper cutting mechanism section D, the sheet paper clamp section C' consisting of sheet paper pressing pieces 56 and 64 presses the same paper P. continues to be fixed, a signal indicating that a seated human body has been detected is input from the seating detection means 96, and then the pressing operation of the pressing pieces 56, 64 is continued until the signal is no longer input,
The pressing operation is released after the signal turns OFF. Therefore, the sheet paper P does not shift while the user is seated or wrap around the buttocks when the user stands up after using the toilet.

Further, a circuit interlock is incorporated in the control section F, and this interlock is such that after the sheet paper P is fed out a predetermined length, the output from the seating detection means 96 is sent to the control section F. As long as the button 103 is pressed, the sheet paper P is not fed out even if the sheet paper feeding button 103 is pressed.

Therefore, after the user is seated, the sheet paper feeding button 103 may be pressed by mistake or by a child or the like.
Even if you press , the sheet paper P will not be fed out.

Further, to explain other configurations in the illustrated embodiment, in FIG. 3, 120 and 1
21 are ventilation holes provided in the outer wall 23a and the side wall 18, respectively, through which air flows in and the rotation motor 4
It is possible to achieve cooling of 0.75.

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, turn on the power switch S provided on the back of the casing body 16 (150).
The control section F and each operating section are initialized, and the sheet paper feeding mechanism section C and the sheet paper clamp section are initialized.
C' and the cutting mechanism D reach the starting position of operation (the state shown in Figure 10), and the power lamp 10
4 lights up (151).

Next, when the sheet paper feeding button 103 is pressed (152), the drive signal from the control section F causes
The rotation motor 75 of the sheet paper cutting mechanism section D and the rotation motor 40 of the sheet paper feeding mechanism section C operate in sequence. The movable plate 50 is rotated counterclockwise by the clockwise rotation of the disc cam 71 driven by the rotation motor 75, so that the movable plate 50 changes from the posture shown in FIG. 10 to the posture shown in FIG. become. That is, on the movable plate 50, there is a sheet paper delivery path 8 communicating with the sheet paper delivery port 85.
will be formed (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 opening/closing switch (not shown) is turned OFF.
Even if the sheet paper feeding button 103 is pressed (152), the drive signal from the control unit F is not transmitted to the rotary motor 4 under the control of the control unit F.
0 (153), and the safety of the 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. Activated, the control unit F prevents the drive signal from being sent 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 casing body 16, the sheet paper P is fed out. Since the sheet paper P will be entangled inside the casing body 16,
Based on the detection output, the control unit F prevents the drive signal from being sent 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 T2 (FIG. 13) is activated at the same time as 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 timer setting time (t1), and at the same time, the position detection sensor 94 detects the sheet paper P normally, that is, within the timer setting time (t2). When the through hole 93 provided in the sheet paper P is detected inside (159cY), the rotary motor 40 stops with the sheet paper P fed out for the set length (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 timer setting time (t1) (159aN), the rotation for feeding the sheet paper The motor 40 is turned off and the paper trouble lamp 106 is turned on (161).

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

Furthermore, the through hole 93 is closed within the timer setting time (t2).
(159cN), the rotation motor 40
and turn off the paper trouble lamp 106.
Turn on (163). Thereafter, the user can take necessary measures such as replenishing paper and checking.

Then, the rotation motor 75 is restarted by a drive signal from the control unit F, and as shown in FIGS.
Clamp between C′ and also between the feed roller 31 and the press roller 32, and then,
When the rotation motor 75 continues to rotate in response to continuous drive signals from the control unit F, tension in the feeding direction is applied to the portion of the sheet paper P located between the two clamp portions (164).

Furthermore, 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 swinging plate 51 cuts the sheet paper P as shown in FIG.
is pressed along the cutting perforation 90, and the sheet paper P is reliably 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 determines whether the user presses the sheet paper feeding button 103 or not. , as long as the seating detection means 96 detects the position, 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 button 103 by mistake or mischievously while seated, the sheet paper P will not be fed out.
Sheet paper P inside the casing body 16
Accidents such as entanglement 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 unit F 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.

The above is after the sheet paper P is cut and held by the cooperation of the movable plate 50 and the swing plate 51 (165), but before it is seated (169), someone forcibly When the sheet paper P is pulled out (166), or the sheet paper P fed out onto the toilet seat body 11 is wet, the sheet paper feeding button 103 is pressed for a predetermined time (about 5 seconds) to remove it. If the user continues to press the button (167), and if for some reason the user does not sit on the toilet seat body 11 within the set time (168), the seat detection means is activated by the reset means built into the control section F. 96, in order to discard the sheet paper P as unusable, the controller F sends a drive signal to the rotation motor 75, and the movable plate 50 and the swing plate 51
10 to release the clamp on the sheet paper P and close the sheet paper outlet 85 (174).
(175).

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

When the sheet paper feeding button 103 is pressed, the sheet paper feeding mechanism section C feeds out onto the top surface of the toilet seat, and the sheet paper clamp section C' and the sheet paper cutting mechanism section D clamp and cut the sheet paper into sheet paper pressing pieces 56, 64. The sheet paper held by the seating detection means 9
6 is turned on when the person sits down, and then turned off when the person leaves the seat, until the off signal is input to the control unit, that is, from immediately after the sheet paper is fed out and cut, until the person stands up after using the toilet. During this period, the cut sheet paper is kept clamped by the sheet paper clamp section C' consisting of the sheet paper pressing pieces 56 and 64, thereby reliably preventing the sheet paper from shifting, falling off, or getting stuck to the buttocks. can do.
