The proximal end side of the toilet seat body 11 is pivotally supported by a pivot 13 at 6 .

Next, the configurations of the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section 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 different diameters is integrally fixed to the feeding shaft 30.

And, as shown in FIG. 4, the feeding roller 31 is
In cooperation with the pressing roller 32 disposed above ((b), the drawn end of the sheet paper P is pressed and clamped, and the sheet paper P is fed out from the sheet paper roll storage section E, which will be described later, onto the toilet seat main body ll, can be supplied.

In FIGS. 4 and 5, reference numeral 33 denotes a suspension support that has a U-shape when viewed from the front and is composed of left and right swinging arms 34.35 and a connecting plate 36 that connects the lower ends of both arms 34.35. The left and right swinging arm 34.3 of the suspension support frame 33 is a frame.

Therefore, when the sheet paper roll shaft 30 is rotated by the rotary motor 40, the press roller 32 is also rotated together with the feed roller 31 via the same transmission gear 42, 43, and the sheet paper P is rotated. The sheet paper 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 passed through the toilet seat body 11. Can you send it out to the top?

Further, as will be described later, the sheet paper P is clamped between the feed roller 31 and the presser 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 press roller 32 can be reliably prevented from rotating, and loosening of the clamping force due to slipping of the press roller 32 or the like can be reliably prevented. Can be done.

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

In this embodiment, the sheet paper cutting mechanism is as follows:
As shown in FIGS. 4 and 5, a plate insertion space 22a provided in the front part of the inclined ceiling wall 22 of the casing body 16
A movable plate 50 is swingably disposed within the movable plate 50, and a lower end front portion of the swing arm 34, 35 of the suspension support frame 33, which is disposed above the movable plate 50, is swingably installed. It is composed of a 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. 52 and 53 are provided in a protruding manner, and the same pivots 52 and 53 are rotatably supported on the left and right side walls 18 and 19 of the casing body 16, respectively.

Moreover, 54.55 is a biasing spring attached to the pivot shaft 52.53 in order to keep the guide roller 70 (described later) in constant contact with the disk cam 71.

Reference numeral 56 denotes 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 clamps the sheet paper P in cooperation with a sheet paper pressing piece 64 of the swinging plate 51, which will be described later. It is.

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

Further, as will be described later, when cutting the sheet paper P, the movable plate 50 can be rotated around the pivot shafts 52 and 53 to take the rotational positions shown in FIGS. 7 to 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 play 51 is formed of a thick sheet paper pressing part 60 and a thin sheet paper cutting part 61, and has a U-shaped cross section opening downward. have.

Such a swinging play) 51 is the sheet paper pressing part 6
Pivot shafts 62.63 are protruded from both ends of the upper part of 0, and the bipolar shafts 62.63 are connected to the left and right swing arms 34°3 of the suspension support frame 33.
It is rotatably supported at the front lower end of 5.

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
The sheet paper P can be clamped by the sheet paper pressing piece 56 without causing slippage.

In addition, return springs 6 are attached to the pivots 62 and 63, respectively.
5.66 is attached, and the spring 65.66 always urges the rocking plate 51 to rotate in the counterclockwise direction in FIG.
．． In cooperation with stoppers 67 and 68 protruding from the inner surface of the swing plate 24, the swing plate is moved to the standby position shown in FIG. 51 can be held.

Next, the drive mechanism of the sheet paper cutting mechanism consisting of the movable plate 50 and the swing plate 51 is as follows.
Various types of configurations are possible, but in this embodiment, the configuration is as shown in FIGS. 4 to 6.

That is, the movable plate 50 has a pivot 52 at its lower part.
．． A guide roller 70 is installed at a position eccentrically rearward from 53. Below the guide roller 70, a disc cam 7 is rotatably abutted against the guide roller 70 and moves the guide roller 70 up and down by rotation.
1, and a rotating shaft 7 to which the disc cam 71 is fixed.
2 has both ends attached to the rectangular mounting plate 1 of the casing body 16.
It is rotatably supported by a pair of bearing stands 73 erected on 7. Further, an example of the extension portion of the rotating shaft 72 is the left side wall 18
through the sheet paper roll mounting wall 23 and the outside 92
It extends into a compartment 23b formed between 3a, and the extension is operatively connected to a rotation motor 75 via a speed reduction device 74.

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 peripheral surface of the disc cam 71 has an irregularly shaped circular cam f! The guide roller 70, which draws a lL trace and has a circumferential surface that comes into contact with the same circumferential surface, moves up and down, and this vertical movement allows the movable plate 50 to swing around the pivot shafts 52 and 53. In conjunction with the swinging of 50, the swinging plate 51 also swings, and the sheet paper P can be effectively cut in the manner described below.

First, in FIG. 4, the sheet paper P is fed onto the toilet seat main body 11 through the sheet paper feed path 8 by the rotation of the feed roller 31 and press roller 32 driven by the sheet paper feed mechanism section C described above. In addition, at this time, the sheet paper P is fed out so that the cutting perforation 90 (see FIG. 3) provided in the sheet paper P is located approximately directly below the cutting blade 61a of the sheet paper cutting section 61 of the swing plate 51. .

Next, when the rotary motor 75 is driven to rotate the disk cam 71 clockwise, the movable plate 50 rotates counterclockwise about the pivot shafts 52 and 53 via the guide roller 70, as shown in FIG. As shown, the sheet paper pressing piece 56 is connected to the sheet paper pressing piece 6 of the swing plate 51.
4 and clamp the sheet paper P. and,
The portion of the sheet paper P located between the clamp portion and the clamp portion that is in contact with the feed roller 31 and the press roller 32 is pressed and bent upward by the rear end of the movable plate 50 to apply tension to the sheet paper P.

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

After that, if the disc cam 71 is further rotated clockwise,
The movable plate 50 further rotates counterclockwise as shown in FIG. 8, while the movable plate 50 causes the swing plate 51 to rotate clockwise. 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 disc cam 71 is rotated clockwise, the movable plate 50 further rotates counterclockwise, and the swing plate 51 rotates clockwise. 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 cut from the perforation 80.

Then, the sheet paper P after cutting is pressed by the pressing piece 56.6.
4 continues to be clamped.

Then, when the user leaves the toilet seat main body 11 after using the toilet,
Further, the disc cam 71 rotates clockwise, and the movable plate 50 rotates clockwise this time to release the clamp of the sheet paper P and take the position shown in FIG. Inflow into channel 8 can be effectively prevented.

In addition, since the sheet paper P is cut by applying the tension and pressing force of the sheet paper P, the sheet paper cutting portion 61 of the swing plate 51 or its cutting blade 61a is cut by a sharp combined pressure or the like. It is not necessary to form such a shape, and it can also be formed of rounded ceramics, corrosive and wear-resistant synthetic resin, or the like.

Therefore, even when used for a long period of time, frequent replacement of the swing plate 51 due to corrosion or wear can be prevented, and maintenance can be improved.

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

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

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 will be explained.

4 and 5, reference numeral 80.81 is a support rod fitted into the boss portion 37.38 of the suspension support frame 33, which is equipped with a spring 82 inside. Both ends of a hollow roll core 83, which has a roll core 83 attached to its outer circumferential surface, are removably inserted and constructed.

Further, 84 is a sheet paper roll protection cover disposed on the casing main body 16 in a state where the sheet paper roll R is folded into four sections, and the front lower end of the cover is located at the sheet paper delivery port 85 to swing the hanging support frame 33. Moving arm 34.
A cover holder installed between the front lower ends of the casing body 16 is removably engaged and supported on a stop slope 86, and its rear lower end is attached to the upper end of an extended rear wall 87 extending over the upper part of the rear wall 21 of the casing body 16. The agreement is supported.

Further, both ends of the sheet paper roll protection cover 84 engage 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. It matches.

With this configuration, it is possible to prevent the hanging support frame 33 from swinging due to vibrations generated when the sheet paper P is rewound or when the movable plate 50 comes into contact with the swinging plate 51.

In addition, if the sheet paper P becomes entangled in the sheet paper delivery path 8, etc., remove the sheet paper roll protection cover 84 as shown in FIG.
By swinging the paper 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 section 14 provided at the rear of the toilet seat body 11. This is to enable automatic and accurate feeding onto the upper surface of 11.

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

Also, the sheet paper P has perforations for cutting at 90°90
A cutout perforation 91 having a shape that matches the inner shape of the toilet seat body 11 is provided in the center between the toilet seat body 11 and the inside of the flush toilet lO by cutting out the sheet paper P along the cutout perforation 91. A communicating opening may be provided.

However, the cutout perforation 91 is not completely annular, and a non-perforation part 92 is formed between both ends of the rear part, so when the perforation 91 is cut out, the cut out center part is a flush toilet. It will hang down into the IO, and its lower end will be submerged in standing water.

In addition, the reason why the sheet paper P is not completely perforated but has the non-perforated part 92 and the perforation for cutting out 91 is because if the sheet paper P is made perforated, there will be no stiffness, and the sheet paper P will be placed on the toilet seat body. When feeding, it may be bent or
This is because it is almost impossible to form a sheet paper roll R. 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.

In addition, the perforation 91 for cutting out the sheet paper P is
It is possible to prevent the sheet paper P from getting caught up in the feeding roller 31 and the pressing roller 32 during feeding and causing paper jams as much as possible.

In addition, the perforation 91 for cutting out the sheet paper P is
It is possible to provide perforations throughout the toilet seat body 11 in a shape that matches the inner shape of the toilet seat body 11, or 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 has non-perforated portions 9 at regular intervals in the longitudinal direction.
2 and the tip of the perforation 91.
On the other hand, a position detection sensor 94 consisting of a light emitting element and a light receiving element is provided at the front part of the inclined ceiling wall 22 of the casing body 16 corresponding to the through hole 93.

The position detection sensor 94 detects the through hole 95 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 C, and accurately Sheet paper P can be supplied and positioned on the toilet seat body 11.

Note that instead of the through-hole 95, a desired colored mark may be applied to the sheet paper P, and furthermore, the through-hole 95 etc. may be attached not only at the center of the sheet paper P but at any arbitrary position. be able to.

Further, the above-mentioned supply and positioning of the sheet paper P can be performed by the rotation motor 4 without using the above-mentioned position detection sensor 94.
It is also possible to count the number of rotations at 0 using a desired counter and operate the control section F based on the counted value.

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, 10 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, a movable υ
The poot 50 and the swinging poot 57 can be moved from the position shown in FIG. 9 to the position shown in FIG. 10.

The seating detection means 96 may be used to automatically supply sheet paper depending on usage conditions and usage environment. It is also possible to integrate it into A or separate it into a separate body.

Furthermore, in addition to the above-mentioned infrared sensor, the seating detection means 96 may also use a micro switch, a limit switch, etc., or may detect the load when the seat is seated using a load cell, etc.
It is also possible to operate

In addition, in FIG. 1, 97 is a state in which the toilet seat body 11 is not seated (when the toilet seat body 11 stands on its own), and the detection is removed from the toilet seat body 11.
This is an abnormal feeding prevention sensor that cuts off the power to the rotating motor 40 and stops the supply of sheet paper P, and only when the toilet seat body 11 is in a state where it can be seated.
1 is detected to enable operation.

Note that the abnormal delivery prevention sensor 97 may be a microswitch, a limit switch, or the like instead of a normal sensor.

Next, the configuration of the sheet paper feeding mechanism section C, the sheet paper cutting v1 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, in the compartment 23b formed on one side of the casing body 16, a control unit mounting Fitoo is installed upright, and the above-mentioned rotation motor 40, Control panel 101 that controls the operation of 75, etc.
is attached to form the control section F. In addition,
A transformer 102 is also integrally attached to the control panel lot.

Next, the operation section G will be explained as shown in FIGS. 1 and 3.
As is most obvious from the figure, the first mulberry production section G has a button 1031 for feeding sheet paper, a power lamp 104 consisting of a light emitting diode, etc., and a power lamp 104 for dealing with paper jams and paper replenishment on the upper surface of the one side extension part 25 of the casing body 16. It is constructed by installing a paper replenishment lamp 1051, a paper trouble lamp 106, etc., which have a warning function when an abnormality occurs.

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

Further, FIG. 13 shows an example of a control circuit 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 υ, input/output interfaces 110 and 111,
It is composed of a memory M that stores a sheet paper feeding/cutting order program which will be explained below.

The input interface 110 includes a push button 103 for sheet paper feeding, a sensor means 94 for position detection, a seating detection means 96, etc., and a microprocessor control unit υ.
The output interface 111 is interposed between
is interposed between the microprocessor MPU and the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section.

The control unit F is provided with a first timer T1, and the timer TI is activated when the sheet paper feeding button 103 is pressed for a predetermined period of time, for example, 5 seconds, and the sheet paper cutting mechanism This forms a reset means capable of resetting the device to its initial state. That is, the configuration is such that the sheet paper P can be unclamped and the sheet paper outlet 85 can be closed.

Therefore, with this reset means, the toilet seat main body 11
If the sheet paper that has been fed out is twisted or wet, you can reset the sheet paper cutting mechanism to its initial state and easily remove the sheet paper P from the toilet seat body, as described below. , and can be disposed of in the toilet bowl 10.

Further, to explain other configurations in the illustrated embodiment, in FIG. It is possible to aim at cooling.

Below, sheet paper automatic supply toilet seat A with the above configuration
The operation will be explained with reference to the flowcharts shown in FIG. 14 (8) and FIG. 14 (B).

In the non-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. 8 is prevented from invading.

In this state, when using the flush toilet IO now, as shown in FIG.
4 lights up (151).

Then, when you press the sheet paper feeding button 103 (
152) Based on the sheet paper feeding/cutting order program read from the memory M, the control section F generates a drive signal, and the driving signal causes the rotation motor 75 of the sheet paper cutting mechanism section and the sheet paper feeding mechanism to be activated. The rotation motors 40 of section C operate sequentially. The movable plate 50 is rotated counterclockwise by the clockwise rotation of the disc cam 71 driven by the rotation motor 75, and the tenth
The posture shown in the figure changes to the posture shown in FIG. 4.

That is, a sheet paper outlet 8 is provided on the movable plate 50.
A sheet paper delivery path 8 communicating with 5 will be formed (157).

Thereafter, the rotation motor 40 is driven and the sheet paper P is fed out from the sheet paper roll R (15
8).

However, when the sheet paper roll protection cover 84 is not mounted on the casing body 16, the cover safety switch (not shown) is in the OFF state.
Even if you press the sheet paper feeding button 103 (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
), which can ensure the safety of operation.

In addition, the user places the sheet paper P on the toilet seat main body 11.
Even when the user is seated in a state where the sheet paper P is not extended, it is not preferable to extend the sheet paper P onto the seat main body 11. Therefore, the seating detection means 96 is activated and a drive signal is sent to the control unit F to the rotation motor. 40 (154).

In addition, 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 extension prevention sensor 97 detects that the toilet seat main body 11 is in the upright state, and the controller F is prevented from sending a drive signal to the rotation motor 40 (155).

Furthermore, even when the position detection sensor 94 arranged inside the casing body 16 that also serves as paper detection 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 not fed out from the casing. Since the sheet paper P will be entangled in the main body 16, the detection output is used to prevent the control unit F from sending a drive signal to the rotation motor 40 (156).
.

And, if there is no above-mentioned abnormal character condition, as mentioned above,
A drive signal is sent from the control unit F to the rotary motor 40 to drive the rotary motor 40 (15B), and the sheet paper P is fed out from the sheet paper roll R.

Further, the second timer T2 (FIG. 13) operates at the same time as the rotation motor 40 starts driving (159), and
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 tl, and the sheet paper P is fed out onto the toilet seat body 11 within the timer setting time t2. When the provided through hole 93 is detected (159cY), the rotary motor 40 stops with the set length of sheet paper P being fed out onto the toilet seat body 11 (160). Furthermore, at this point,
Cutting perforation 90 located at the rear end of sheet paper P
is located substantially directly below the sheet paper cutting blade 61a of the swinging shaker 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 tl (L59a
N) turns off the automatic modem 40 for sheet paper feeding and turns on the paper trouble lamp 106 (1).
61).

Furthermore, even if the sheet paper P is detected within the timer setting time tl, the next timer setting time t2 (rotation morph 40
If the position detection sensor 94 detects the through hole 93 earlier than the count from the start of driving of the
At the same time as turning off the rotation motor 40, the paper supply lamp 10
5 is turned on (162).

Further, 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 (16
3).

Then, the rotation motor 75 is restarted by a drive signal from the control unit F, and as shown in FIGS. and press roller 3
When the rotation motor 75 continues to be driven by continuous drive signals from the control unit F, tension is applied in the feeding direction to the portion of the sheet paper P located between the two clamped portions. becomes (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 swinging plate 51 as shown in FIG.
However, the sheet paper P is pressed along the cutting perforations 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, 64 (165).

After that, when the user sits on the toilet seat body 11 (169
), the seating detection means 96 detects that the seat is seated 17
0) Based on the detection output, the control unit F performs control so that even if the sheet paper feeding bokun 103 is subsequently pressed, the drive signal is not sent to the rotation motor 40 as long as the seating detection means 96 detects the detection. (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, thereby ensuring that accidents such as the sheet paper P0) becoming tangled in the casing body 16 are prevented. can be prevented.

When the user leaves the toilet seat body 11 after using the toilet (
172), the seating detection means 96 is turned off (173).
), based on the OFF signal, the control unit F controls the rotation motor 7.
The drive JJ signal is sent again to the rotary motor 75 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, 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. You can take (174) (175).

After that, the cleaning device is driven to clean the inside of the flush toilet bowl 10,
Due to the force of the cleaning water, the separated portion of the sheet paper P can be drawn in and flowed out together with the cleaning water and dirt.

In the above step, after the sheet paper P is cut and held by the cooperation of the movable plate 5° and the swing plate 51 (165), but before it is seated (169), someone forcibly cuts the sheet paper P. When the paper P is pulled out (166), or the sheet paper P fed out onto the toilet seat main body 11 is wet, the sheet paper feeding button 103 is kept pressed for a predetermined time (about 5 seconds) to remove it. If the user does not sit on the toilet seat main body 11 within a predetermined period of time (168) for some reason, the sheet paper P is reset by each reset means independently of the seating detection means 96. It should be discarded as unused. (The controller 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, and releases the clamp on the sheet paper P. At the same time, 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.

That is, in the present invention, the sheet paper cutting mechanism section is controlled by the control section F so as to reliably clamp the rear end of the sheet paper P even after cutting the sheet paper P. Even if the user slightly moves his/her body, there is no fear that the sheet paper P will fall from the toilet seat main body 11, and the user can use the toilet comfortably.

Furthermore, in the present invention, when the sheet paper P fed onto the toilet seat main body 11 is twisted or wet, the sheet paper cutting mechanism can be cut by pressing and holding the sheet paper feeding button 103 for a predetermined period of time. Since the initial state can be restored, the sheet paper P can be easily taken out from the toilet seat main body 11 by releasing the clamp, etc., and disposed of in the toilet bowl 10, and the next sheet paper P can be quickly returned to the toilet seat main body ll. You will be able to move it upwards.
