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

First, to explain the sheet paper feeding mechanism part C, as shown in FIGS. A feeding roller 31 having approximately the same length but different diameters is integrally fixed to the feeding shaft 30.

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

In addition, in FIGS. 4 and 5, reference numeral 33 denotes a suspension support that is U-shaped in front view 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. It is a frame, and the same suspension support frame 3

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

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

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

And the left end of the sheet paper feeding shaft 30,
Transmission gears 42 and 43 are fixed to the left end of the roller attachment 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 a sheet paper delivery path 8 is formed between the inclined ceiling wall 22 of the functional part casing 15 and the lower surface of the hanging support frame 33. It can be delivered onto the toilet seat body 11 through the toilet seat body 11.

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

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

In this embodiment, the sheet paper cutting mechanism D is swingable in a plate insertion space 22a provided at the front of the inclined ceiling wall 22 of the functional unit casing 15, as shown in FIGS. 4 and 5. A movable plate 50 disposed above the movable plate 50 and a swing arm 3 disposed above the movable plate 50 of the suspension support frame 33.
4 and 35, and a swing plate 51 swingably installed between the lower end front portions of the members 4 and 35.

First, to explain the configuration of the movable plate 50, as shown in FIGS. 4 and 5, the movable plate 50 is formed from a long and wide rectangular flat plate extending in the left-right direction, and has pivots at both ends. 5
2, 53 are provided protrudingly, and the same pivots 52, 53,
left and right side walls 18 of the functional unit casing 15, respectively;
It is rotatably supported on 19.

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.

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

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

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

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

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

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

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

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

Next, the movable plate 50 and the swing plate 5
As the drive mechanism of the sheet paper cutting mechanism D consisting of 1, various forms can be considered.
This embodiment is constructed as shown in FIGS. 4 to 6.

That is, the guide roller 70 is attached to the movable plate 50 at a lower portion thereof and at a position eccentric to the rear from the pivot shafts 52 and 53. The guide roller 70 is located below the guide roller 70.
A disc cam 71 is provided which rotatably contacts the guide roller 70 and moves the guide roller 70 up and down by rotation, and a rotating shaft 72 to which the disc cam 71 is fixed is
Both ends thereof are rotatably supported by a pair of bearing stands 73 erected on the rectangular mounting plate 17 of the functional part casing 15 . 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 connected to each other via the sheet paper pressing pieces 56 and 64. Since the sheet paper P is clamped, slips at the clamped portion can be reliably prevented.

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

Further, as shown in FIG. 9, if the 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.

The sheet paper P after cutting continues to be clamped by the pressing pieces 56 and 64.

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.

In this way, in this embodiment, the movable plate 50
functions as an outlet opening/closing member, and the rotation motor 75 functions as a closing means.

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.

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

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

Next, the functional part casing 15 including the sheet paper feeding mechanism part C and the sheet paper cutting mechanism part D
The configuration of the sheet paper roll storage section E disposed above will be explained.

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 protection cover disposed on the functional part casing 15 in a state surrounding the sheet paper roll R, and its front lower end is connected to the swing of the suspension support frame 33 at the sheet paper outlet 85. It is removably engaged with and supported on a cover receiving plate 86 installed between the front lower ends of the moving plates 34 and 35, and the rear lower end is an extended rear wall 8 extending over the upper part of the rear wall 21 of the functional part casing 15.
It is engaged and supported by the upper end of 7.

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, if the sheet paper P becomes entangled in the sheet paper delivery path 8, etc., as shown in FIG. 11, after removing the sheet paper roll protection cover 84, swing the hanging support frame 33 forward. This allows the entangled sheet paper P to be easily taken out.

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

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

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

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

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

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

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

Furthermore, as shown in FIGS. 3 and 12, the sheet paper P is arranged at regular intervals in the longitudinal direction.
A position detection through hole 93 is provided between the non-perforated portion 92 and the tip of the perforation 91, and a hole 93 is provided at the front of the inclined ceiling wall 22 of the functional unit casing 15 corresponding to the through hole 93. , a position detection sensor 94 consisting of a light emitting element and a light receiving element is provided.

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

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

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

Further, in FIG. 1, reference numeral 96 denotes a seating detection means consisting of a reflective infrared sensor or the like provided on the inner surface of the one side extension 25 of the functional part casing 15, and after the user is seated on the toilet seat body 11, When the user leaves the toilet seat main body 11 after a certain period of time (for example, 10 seconds) has elapsed, a take-off signal is generated, the controller F is activated, and the rotating motor 75, which also functions as the outlet closing means, is driven. The movable plate 5 is moved so as to release the clamp on the sheet paper P and to block the entry of dirty water into the sheet paper delivery path 8.
0 and the swing plate 51 are moved from the posture shown in FIG. 9 to the posture shown in FIG. This prevents the intrusion of sewage.

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

Furthermore, in addition to the infrared sensor described above, the seating detection means 96 can also use a micro switch, a limit switch, etc., or detect the load at the time of seating with a load cell or the like to operate the control section F.

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.

Incidentally, the abnormal delivery prevention sensor 97 may be replaced with a normal sensor, and may be a micro switch, a limit switch, or the like.

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

As shown in FIG. 5, a control unit mounting plate 100 is provided upright in a compartment 23b formed on one side of the functional unit casing 15.
A control panel 101 for controlling the operation of the rotation motors 40, 75, etc. described above is attached.
A control section F is formed. In addition, the control panel 10
1, the transformer 102 is also integrally attached.

Next, the operation section G will be explained.As is most obvious from FIGS. 1 and 3, the operation section G
is a push button 103 for sheet paper feeding on the upper surface of the one side extension part 25 of the functional part casing 15;
A power lamp 104 consisting of a light emitting diode or the like,
It is constructed by installing a paper replenishment lamp 105, a paper trouble lamp 106, etc., which have a warning function in the event of an abnormality such as a paper jam or paper replenishment.

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 the circuit configuration of the control section F that controls the operation of the automatic sheet paper supplying toilet seat A.

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

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

And inside the above microprocessor MPU,
A lock circuit Q is built in, and as long as the output from the seating detection means 96 is sent to the control unit F after the sheet paper P has been fed out for a predetermined length, the lock circuit Q is activated by the sheet paper feeding pushbutton. The sheet paper P is configured not to be fed out even if the button 103 is pressed.

Therefore, after the user is seated, the push button 1 for feeding sheet paper may be pressed by mistake or by a child, etc.
Even if 03 is pressed twice or more, the sheet paper P will not be fed out.

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

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

In the de-energized state, the movable plate 50 of the functional part casing 15 closes the sheet paper outlet 85 at one end and functions as an opening/closing member for the outlet, as shown in FIG. This prevents the sheet paper from entering the sheet paper delivery path 8 from the outlet 85.

When the flush toilet 10 is used in this state, when the power switch S provided on the back surface of the functional part casing 15 is turned on (150) as shown in FIG. 5, the power lamp 104 lights up (151). .

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

Thereafter, the rotation motor 40 is started and the sheet paper P is fed out from the sheet paper roll R (158).

However, the sheet paper roll protective cover 84
is not installed on the functional part casing 15, the cover safety switch (not shown) is turned OFF.
Therefore, even if the sheet paper feeding push button 103 is pressed (152), no drive signal is sent from the control unit F to the rotation motor 40 under the control of the control unit F ( 153N), which can ensure the safety of operation.

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. It is activated to prevent the control unit F from sending a drive signal to the rotation motor 40 (154N).

Furthermore, 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 (155N).

Furthermore, even when the position detection sensor 94, which also serves as paper detection and is arranged inside the functional unit casing 15, detects that the sheet paper P is present in the sheet paper delivery path 8 within the functional unit casing 15,
The sheet paper P is fed out using the functional part casing 1.
Since the sheet paper P will be entangled in the rotation motor 40, the detection output is used to prevent the control unit F from sending a drive signal to the rotation motor 40 (156).

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

Further, the timer T (FIG. 13) is activated at the same time as the rotation motor 40 starts to be driven (159). and,
The sheet paper P is fed out onto the toilet seat body 11, and then the position detection sensor 94 normally
That is, when the sheet paper P is detected within the set time t1 and the through hole 93 provided in the sheet paper P is detected within the set feed time t2 (159cY), the set length sheet paper P is fed onto the toilet seat main body 11. The rotation motor 40 stops in this state (160).

Note that at this point, the cutting perforation 90 located at the rear end of the sheet paper P is located approximately directly below the sheet paper cutting blade 61a of the swing plate 51.

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

Furthermore, even if the sheet paper P is detected within the set time t1, the next timer set time t2 (rotation motor 4
If the position detection sensor 94 detects the through hole 93 earlier than (counting from the start of driving at 0),
(159bY) similarly turns off the rotation motor 40 and turns on the paper supply lamp 105 (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 (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. 7 and 8, the sheet paper P is clamped between the sheet paper pressing pieces 56 and 64 and fed out. When the roller 31 and the presser roller 32 are also clamped, and then the rotary motor 75 continues to be driven by continuous drive signals from the control unit F, the portion of the sheet paper P located between both clamped portions is moved in the feeding direction. Tension will be added (164).

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

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

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

Therefore, even if the user presses the sheet paper feeding push button 103 by mistake or mischievously while seated, the sheet paper P will not be fed out, thereby preventing the sheet paper P from getting tangled in the functional unit casing 15. Accidents 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 activates the rotation motor 75 as the closing means. The drive signal is sent 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, and the movable plate 50 functions as an outlet opening/closing member.

That is, while the clamp of the sheet paper P is released, the movable plate 50 closes the sheet paper delivery port 85, and it is possible to reliably prevent dirty water from entering the sheet paper delivery path 8 through the delivery port 85. Functional part casing 15
Can be taken within (174) (175).

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

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

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

That is, in this embodiment, when the user leaves the seat after using the toilet, the seating detection means detects the sitting movement and drives the rotation motor 75 as the closing means to cut the sheet paper cutting mechanism D. Since the movable plate 50 is controlled to close the sheet paper outlet 85 as an opening/closing member for the outlet, it is effectively possible to prevent sewage from entering the functional unit casing 15 through the sheet paper outlet 85. Therefore, damage to the functional parts inside the functional part casing 15 can be prevented as much as possible.
