Abstract

PURPOSE:To surely prevent a seat paper from positional deviation, dropping-out and attachment around the hip by keeping clamping of the seat paper with a seat paper pressing piece of a cutting mechanism until a user eases nature and stands up immediately after a seat paper is drawn, clamped, and cut. CONSTITUTION:When a seat paper drawing button 103 is depressed, the seat paper P is drawn out to the upper surface of a stool by a seat paper drawing mechanism C, clamped and cut off by a seat paper cutting mechanism D, while being held by seat paper pressing pieces 56, 64. A seating detecting means 96 is turned on once by the seating of a human body and then turned off by its subsequent separation from the stool. Since the seat paper pressing pieces 56, 64 keep clamping of the seat paper until the turning-off signal is input to a controller, the seat paper can be surely prevented from positional deviation, dropping-out and attaching around the hip.

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)
(32) are engaged by the transmission gears (42) and (43), so as long as the rotary motor (40) is stopped, not only the feed roller (31) but also the presser roller (32)
) 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, the sheet paper cutting mechanism section (D) is connected to the casing body (16) as shown in FIGS. 4 and 5.
A movable plate (50) is swingably disposed in a plate insertion space (22a) provided at the front of the inclined ceiling wall (22)
), and a swinging plate (51) that is arranged above the movable plate (50) and swingably installed between the front lower end of the swinging arm (34035) of the suspension support frame (33). It consists of

First, the configuration of the movable plate (50) will be explained. 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 (52) and (53) protruding from both ends, and the pivots (52 and 53) are connected to the casing, respectively. It is rotatably supported on the left and right side walls (18) and (19) of the main body (16).

In addition, (54) and (55) are the guide rollers (
70) is a biasing spring attached to the pivot shafts (52) and (53) in order to keep the disc cam (71) in constant contact with the disc 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 the sheet paper pressing piece (64) of the swinging plate (51), which will be described later. and clamps the sheet paper CP).

Then, when rolling out the sheet paper (P) onto the toilet seat body (11), as shown in Figure 4, move the movable plate (
The upper surface (50a) of 50) is made approximately parallel to the upper surface of the inclined ceiling wall (22), and a sheet paper delivery path (8) is arranged above it.
can be formed.

In addition, as will be described later, when cutting the sheet paper (P), the movable plate (50) is rotated with the pivots (52) (53).
) to assume 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) that cooperates with the movable plate (50) to cut the sheet paper (P) will be explained.

As shown in FIG. 4, the swing plate (51) is formed of a thick sheet paper pressing part (60) and a thin sheet paper cutting part (61) when viewed from the side, and has an opening facing downward. It has a U-shaped cross section.

This swing plate (51) has pivots (62) (63) protruding from both ends of the upper part of its sheet paper pressing portion (60), and both assembly shafts (62) (63) are connected to the hanging support frame. (33
) is rotatably supported at the front lower end of the left and right swing arms (34) (35).

Furthermore, the swinging 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), and the pressing piece (64) and the movable plate (50) are connected to each other. Sheet paper pressing piece (56)
Accordingly, the sheet paper (P) can be clamped without slipping.

In addition, return springs (65) (66) are attached to the pivots (62) (63), respectively, and the springs (65) (66) keep the swing plate (51) at all times as shown in FIG. It is biased to rotate counterclockwise, and works with stoppers (67) and (68) protruding from the inner surfaces of the sheet paper roll mounting walls (23 and 24) to move to a standby position (not shown in FIG. 4). That is, the swing plate (51) can be held such that the sheet paper cutting section (61) is in a position retracted from the sheet paper delivery path (8).

Next, the movable plate (50) and the swing plate (51
) The drive mechanism for the sheet paper cutting mechanism (D) may take various forms, but in this embodiment, it is constructed as shown in FIGS. 4 to 6.

That is, the guide roller (70) is attached to the movable plate (50) at a position eccentric to the rear from the pivot (52053) at its lower part. The lower part of the guide roller (70) is in rotatable contact with the guide roller (70), and by rotation, the guide roller (70) is in contact with the guide roller (70).
) is installed, and the rotary shaft (72) to which the disc cam (71) is fixed has both ends connected to the rectangular mounting plate (17) of the gauging body (16). It is rotatably supported by a pair of bearing stands (73) erected above. Further, the − side extension portion of the rotating shaft (72) passes through the left side wall (18) and extends through the sheet paper roll mounting wall (2).
3) and the outer wall (23a), and the extension part is operatively connected to a rotation motor (75) via a speed reduction device (74).

With this configuration, when the rotary motor (75) is driven, the rotary shaft (72) rotates, and the disc cam (71) that is integrated with the rotary shaft (72) also rotates about the axis of the rotary shaft (72). It will rotate as. However, the disk cam (7
Since the center of 1) is eccentric from the axis of the rotating shaft (72), the peripheral surface of the disc cam (71) draws a cam locus of an irregularly shaped circle, and the guide roller (
70) moves up and down, and this up and down movement allows the movable plate (50) to swing around the pivots (52) and (53), and in conjunction with the swinging of the movable plate (50), The swinging plate (51) also swings to allow the sheet paper (P) to be effectively cut in the manner described below.

First, in FIG. 4, the sheet paper (P) is passed through the sheet paper delivery path (8) by the rotation of the delivery roller (31) and press roller (32) driven by the sheet paper delivery mechanism (C) described above. It is rolled out onto the toilet seat body (11). In addition, at this time, the cutting perforation (90) (see Fig. 3) provided in the sheet paper (P) is almost directly below the cutting blade (61a) of the sheet paper cutting part (61) of the swing plate (51). It will be rolled out so that it is located at .

Next, the rotary motor (75) is driven to rotate the disc cam (71).
) is rotated clockwise, the movable plate (50) is rotated counterclockwise about the pivots (52) and (53) via the guide roller (70), and as shown in FIG. The paper pressing piece (56) is connected to the swing plate (
Clamp the sheet paper (P) together with the sheet paper pressing piece (64) of 51). Then, the ramp part, the feeding roller (31) and the holding roller (32)
) is pressed upward at the rear end of the movable plate (50) to apply tension to the sheet paper (P); The feeding roller (31) and the pressing roller (32) are engaged with each other by transmission gears (42) and (43), and the movable plate (50) and the swinging plate (51) are connected to the sheet paper pressing piece (56). N (64)
Since the sheet paper (P) is clamped through the clamp, slippage 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. (51) will be rotated clockwise. Therefore, the cutting blade (61a) provided at the tip of the sheet paper cutting portion (61) of the swing plate (51) 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) further rotates counterclockwise, and the swing plate (51) rotates clockwise. By the same rotation, the swing plate (51)
The cutting blade (61a) of the sheet paper cutting unit (61) further presses the sheet paper (P) downward to apply tension, and as a result, the sheet paper (P) is cut from the perforation (90). It turns out. Then, the sheet paper (P) after cutting is divided into pressing pieces (56) (64)
continues to be clamped by.

When the user leaves the toilet seat body (11) after using the toilet, the disc cam (71) further rotates clockwise, the movable plate (50) rotates clockwise this time, and the sheet paper ( By releasing the clamp P) and 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.

In addition, since the sheet paper (P) is cut by applying tension and pressing force to the sheet paper (P), the sheet paper cutting part (61) of the swing plate (51) or its cutting blade is used to cut the sheet paper (P). (61a) does not need to be made of sharp metal or the like, but can also be made of 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 shaped 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, (80) and (81) are support rods fitted into the boss portions (37) and (38) of the suspension support frame (33), which is equipped with a spring (82) inside. Sheet paper roll (R) by support rods (80) (81)
Both ends of a hollow roll core (83) with a roll core (83) attached to its outer circumferential surface are removably inserted and constructed.

Further, (84) is a sheet paper roll protective cover disposed on the casing body (16) in a state surrounding the sheet paper roll (R), and its front lower end is located at the sheet paper outlet (85). Hanging support frame (33
) The cover holder installed between the front lower ends of the swing arms (34) and (35) is removably engaged and supported on the stop plate (8i), and the lower rear end is connected to the rear wall of the casing body (16). (
21) is engaged with and supported by the upper end of an extended rear wall (87).

Furthermore, as shown in FIGS. 5 and 11, both ends of the sheet paper roll protective cover (84) have fitting grooves (88) recessed along the inner edge of the sheet paper roll mounting wall C23). ) (89).

With this configuration, when rewinding the sheet paper (P), or when the movable plate (50)
The suspension support frame (33) is damaged due to vibrations generated when it comes into contact with
can be prevented from swinging.

In addition, in the unlikely event that the sheet paper (P) becomes jammed or entangled in the sheet paper feed path (8), etc., causing trouble, remove the sheet paper roll protection cover (84) as shown in Figure 11. After that, by swinging the hanging support 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 roll (R). It is meant to be cut and used.

The reason why the sheet paper (P) is formed from a sheet paper roll (R) is that the sheet paper (P) for multiple people can be stored compactly in the functional section (14) provided at the rear of the toilet seat body (11). This is for storing the toilet seat, and also for automatically and accurately extending it to the top surface of the toilet seat body (11).

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) will be cut along the perforations (90).

In addition, the sheet paper (P) has cutting perforations <90
) (90) is provided with a cutout perforation (91) with a shape that matches the inner shape of the toilet seat body (11), and the sheet paper (90) is cut out along the cutout perforation (91). P) by cutting out the flush toilet (10
) can be provided with an opening that communicates with the inside.

However, the cut-out perforation (91) is not completely annular, and a non-perforated part (92) is formed between both ends of the rear part, so when the cut-out perforation (91) is cut out, The cut central portion will hang down into the flush toilet bowl (10), and its 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 cutout perforation (91)
) is provided with a hole in the waist.
This is because when the sheet paper (P) is fed onto the toilet seat body (11), it is bent and it is almost impossible to form a sheet paper roll (R).

In other words, the perforation for cutting out (91) and the non-perforated part (
The sheet paper (P) provided with 92) has sufficient stiffness and can easily be automatically fed and rolled.

In addition, perforations for cutting out sheet paper (P) (9
1) can prevent as much as possible the sheet paper (P) from getting caught up in the feeding roller (31) and the pressing roller (32) during feeding and causing a paper jam.

In addition, perforations for cutting out sheet paper (P) (9
In 1), it is possible to have perforations throughout the toilet seat body (11) in a shape that matches the inside shape, or it is also possible to have perforations here and there and cuts elsewhere. .

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

6. Then, the position detection sensor (94) detects the position detection through hole (93) when the sheet paper (P) is unwound for a predetermined length from the sheet paper roll (R), Stop the operation of the side part (C) of the sheet paper feeder and accurately feed the sheet paper (P) into the toilet seat body (11).
It can be supplied and positioned on top.

In addition, the interval between the position detection through holes (93) (93) at the end of the sheet paper roll (R) is made shorter than the interval at other parts, and the position detection sensor ( The end of the roll (R) can be detected by shortening the detection interval of the through hole (93) of the roll (94).

In addition, instead of such a through hole (93), sheet paper (
A desired colored mark may be applied to the sheet paper (P), and the attachment position of the through hole (93) etc. can be not only at the center of the sheet paper (P) but also at any arbitrary location.

In addition, the above-mentioned supply and positioning of sheet paper (P) are as follows:
Counting the number of rotations of the rotary motor (40) with a desired counter without using the position detection sensor (94),
This can also be done by operating the control section (F) based on the counted value.

In addition, in Fig. 1, (96) is the casing body (1
6) is a seating detection means consisting of a reflective infrared sensor etc. provided on the inner surface of the - side extension part (25), and after the user sits on the toilet seat main body (11), it detects the presence of the user for a certain period of time (for example, 5 seconds).
When the user leaves the toilet seat body (11) after a while, a detection signal is generated, the control unit (F) is activated, the rotation motor (75) is driven, and the sheet paper (P) is clamped. At the same time, the sewage sheet paper delivery path (
8) to block the movable plate (50) from entering the
and the swing plate (51) from the position shown in FIG.
The position can be moved to the posture shown in Figure 0.

The seating detection means (96) can be integrated into the automatic sheet paper supply toilet seat (A) or separated into a separate body, depending on the usage conditions and usage environment.

Further, the seating detection means (96) may include, in addition to an infrared sensor or the like, a microswitch, a limit switch, or a load cell that detects the load when the passenger is seated.

In addition, in FIG. 1, (97) is a control unit that is detected when the toilet seat body (11) is not seated (when the toilet seat body (11) is independent). (F) is an abnormal feeding prevention sensor that cuts off the power to the rotation motor (40) and stops the supply of sheet paper (P), and the toilet seat body (11) is in a state where it can be seated. The toilet seat main body (11) is detected only at certain times and made operable.

In addition, a microswitch, a limit switch, etc. can also be used for 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 (D), and the control section (F) that controls the operations of various sensors and detection means will be explained.

As shown in FIG. 5, the control unit mounting plate [100
) is installed upright, and on the control unit mounting plate (100),
A control board (101) that controls the operation of the rotation motors (40) and (75) described above is attached, and the control unit (
F) is formed.

Next, the operation part (G) will be explained. As is most obvious from FIGS. 1 and 3, the operation part (G) is provided with a A button for feeding sheet paper (103), a power rung (104) consisting of a light emitting diode, etc., a paper supply lamp (105) with a warning function in the event of an abnormality such as a paper jam or paper replenishment, and a paper trouble lamp (106). ), etc.

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

In addition, Fig. 13 shows the sheet paper automatic supply toilet seat (A).
The configuration of the control device that controls the operation of is shown.

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). , (111) is the control unit (F)
This is an output interface interposed between the sheet paper feeding mechanism section (C), sheet paper cutting mechanism section (D), etc.

The control section (F) has the functions shown in FIGS. 14 (8) to 14 (B
) is programmed, and in particular, when the sheet paper feeding button [103] is pressed during the program, the sheet paper feeding mechanism (C) feeds the sheet paper (P) to the toilet seat body (11).
), the sheet paper cutting mechanism (D)
Even after cutting the paper (P), the sheet paper pressing pieces (56) and (64) continue to press and fix the paper (P), and the seating detection means (96) generates a signal indicating that a human body has been seated. is input, and then the pressing operation of the pressing pieces (56) and (64) is continued until the signal is no longer input, and the pressing operation is canceled after the signal is turned OFF. Therefore, the sheet paper (P) does not slip while sitting or cling to the buttocks when standing up after using the toilet.

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

Therefore, even if the user presses the sheet paper feeding button (103) by mistake or a child mischievously presses the sheet paper feeding button (103) after sitting, the sheet paper (P) will not be fed out.

Further, to explain other configurations in the illustrated embodiment, in FIG. 3, (120) and (121) are ventilation holes provided in the outer wall (23a) and the side wall (18), respectively, which allow air to flow in. Rotation motor (40) (75

Regarding the operation of ^), Figures 14 (A) to 14 (B)
This will be explained with reference to the flowchart shown in .

In the de-energized state, the movable plate (50) in the casing body (16) closes the sheet paper outlet (85) at all possible times, as shown in FIG. (85) into the sheet paper delivery path (8).

In this state, when using the flush toilet (10) now, as shown in Fig. 5, when the power switch (S) provided on the back of the casing body (16) is turned on, the control unit (F) is turned on (150). and each operating section is initialized, the sheet paper feeding mechanism section (C) and the same cutting mechanism section (0) are at the start position of operation (the state shown in Fig. 10), and the power lamp (
104) lights up (151).

Next, when the sheet paper feeding button (103) is pressed (152), the drive signal from the control section (F) causes
Rotation motor (75) of sheet paper cutting mechanism (D)
and the rotating motor (40) of the sheet paper feeding mechanism (C).
) are activated in sequence. The movable plate (50) is rotated counterclockwise by the clockwise rotation of the disc cam (71) driven by the rotation motor (75), and the movable plate (50) is rotated from the position shown in FIG. 10 to the position shown in FIG. You will have to take a stance. That is, on the movable plate (50), there is a sheet paper outlet (
A sheet paper delivery path (8) communicating with 85) is formed (157).

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

However, if the sheet paper roll protection cover (84) is not attached to the casing body (16), the cover opening/closing switch (not shown) is in the OFF state, so the sheet paper feeding button (103) cannot be pressed. Also (152), under the control of the control unit (F), the drive signal is not sent from the control unit (F) to the rotation motor (40) (153), ensuring operational safety. can.

Furthermore, even if the user is sitting on the toilet seat body (11) with the sheet paper (P) not being fed out, it is preferable to feed out the sheet paper (P) onto the toilet seat body (11). Therefore, the seating detection means (96) is activated and the control section (F) transmits the drive signal to the rotation motor (4).
0) (154).

In addition, since it is not preferable for the sheet paper (P) to be fed out onto the toilet seat body (11) when the toilet seat body (11) is standing, the abnormal feeding prevention sensor (97) is connected to the toilet seat body (11).
11) detects that there is a standing state, and the control unit (F)
However, the drive signal is not sent to the rotation motor (40) (155).

Furthermore, the position detection sensor (94), which also serves as paper detection, arranged in the gauging body (16) detects that the sheet paper (P) is in the sheet paper delivery path (8) in the casing body (16). In this case, the feeding of the sheet paper (P) causes the sheet paper (P) to become entangled within the casing body (16), so the control section (F) uses the same detection output to send a drive signal to the rotation motor. I try not to send it to (40) (156).

If there is no abnormal condition mentioned above, as mentioned above,
A drive signal is sent from the control unit (F) to the rotary motor (40) to drive the rotary motor (40) (158), and the sheet paper (P) is fed out from the sheet paper roll (R).

Additionally, the timer (T2) (Fig. 13) operates (159) when the rotation motor (40) starts driving, and the sheet paper (P) is fed out onto the toilet seat body (11), and then the position is detected. The sensor (94) detects the sheet paper (P) normally, that is, within the timer setting time (tl), and detects the through hole (93) provided in the sheet paper (P) within the timer setting time (t2). ) is detected (159CY), the set length sheet paper (P)
The rotary motor (40) stops in the state where it is extended (16
0).

Note that at this point, the cutting perforation (90) located at the rear end of the sheet paper (P) is
) is located approximately directly below the sheet paper cutting blade (61a).

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 (tl) (159aN), The sheet paper feeding rotary motor (40) is turned off and the paper trouble lamp (106) is turned on (161).

Also, hold the sheet paper (P) for the timer setting time (tl).
), the position detection sensor (94) detects the through hole (93) earlier than the next timer setting time (t2) (counting from the start of driving the rotation motor (40)). If (159bY), the rotation motor (40) is similarly turned off and the paper supply lamp (105) is turned on (162).

Furthermore, if the through hole (93) is not detected within the timer setting time (t2) (159 cN), the rotation motor (40)
is turned off and the paper trouble lamp (106) is turned on (163), and thereafter the user can take necessary measures such as replenishing paper and checking.

Then, the rotation motor (75) is restarted by the drive signal from the control section (F), and as shown in FIGS. 7 and 8,
Press the sheet paper (P) with the sheet paper pressing piece (56
) (64) while clamping between the outlet and the roller (64).
31) and the presser roller (32), and then, when the rotation motor (75) continues to rotate in response to continuous drive signals from the control unit (F), the sheet paper ( Tension in the feeding direction is applied to the portion P) (164).

Furthermore, the rotation motor (
75) is driven, 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.
Sheet paper (P) is pressed along the cutting perforations (90), and the sheet paper (P) is
will definitely be cut (165).

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

After that, when the user sits on the toilet seat body (11) (1
69) The seating detection means (96) detects the seating 170), and based on the detection output, the control unit (F)
Thereafter, even if the sheet paper feeding button (103) is pressed, as long as the seat detection means (96) detects the seat, 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. ) can reliably prevent accidents such as entanglement.

When the user leaves the toilet seat 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 (F) rotates. A drive signal is sent to the motor (75) again to rotate the rotary motor (75). As a result, the movable plate (50) and the swing plate (51) assume the state shown in FIG. 10.

That is, the clamp of the sheet paper (P) is released while the movable plate (50) is connected to the sheet paper delivery path (8) of the waste water through the sheet paper delivery opening (85).
(174) (17
5).

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) together with the flushing water and dirt and allows it to flow out.

In the above step, after the sheet paper (P) is cut and held (165) by the cooperation of the movable plate (50) and the swinging plate (51), and before the sheet paper (P) is seated (169), , someone forced the sheet paper (P
) is pulled out (166), or the toilet seat body (
11) If the sheet paper (P) fed out above is wet and the sheet paper feeding button (103) is kept pressed for a predetermined time (approximately 5 seconds) to remove it (167), further, If the user does not sit on the toilet seat main body (11) for some reason (168), the seat paper (P ) in order to discard it as unusable, the control unit (F)
sends a drive signal to the rotation motor (75), causes the movable plate (50) and the swing plate (51) to assume the state shown in FIG. 10, releases the clamp on the sheet paper (P), and The sheet paper outlet (85) can be closed (174) (175).

With the configuration and operation described above, this embodiment has the following features:
The following effects will be achieved.

When the sheet paper feeding button (103) is pressed, the sheet paper feeding mechanism (C) feeds out onto the top surface of the toilet seat, and the sheet paper cutting mechanism (D) clamps and cuts the sheet paper to form a sheet paper pressing piece (56) ( 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, and until the off signal is input to the control unit, that is, immediately after the sheet paper is fed out and the clamp is cut and held, and after finishing the toilet. Until it stands up, the sheet paper pressing pieces (58) (64) of the cutting mechanism (D)
By continuing to clamp the sheet paper that has been cut and held, it is possible to reliably prevent the sheet paper from shifting, falling off, or getting stuck in the buttocks.
