Further, as shown in FIGS. 3 and 4, the sheet paper roll mounting wall 23.24 and the outer walls 23a, 24a have their front portions projected forward from the front wall of the casing body 16 to form an extending portion 25.26. , with both extending parts 25°26
The base end side of the toilet seat body 11 is pivotally supported by a pivot 13.

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 the fourth leap, the feeding roller 31 is
In cooperation with the pressing roller 32 disposed above, the sheet paper P is pressed and clamped on the drawn-out end of the sheet paper P, and the sheet paper P is transferred from the sheet paper roll storage section E to be described later.
can be fed onto the toilet seat main body 11.

In FIGS. 4 and 5, reference numeral 33 denotes a suspension support which is U-shaped when viewed from the front and is composed of left and right swinging arms 34 and 35 and a connecting plate 36 that connects the lower ends of both arms 34 and 35. The horizontal swing arm 34 of the suspension support frame 33 is a frame.
The upper end of 35 is swingably attached to the sheet paper roll mounting wall 23.24 via a cylindrical boss portion 37.38.

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

As shown in FIG. 4, a line L1 connecting the presser roller 32 and the cylindrical boss portion 37.38 that pivotally supports the left-right swing arm 34.35 of the suspension support frame 33 is the cylindrical boss portion 37°38. Since it is inclined with respect to the perpendicular line L2 extending downward from
In the normal contact state, the press roller 32 comes into pressure contact with the feeding roller 31, and can clamp the sheet paper P 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.

Transmission gears 42 and 43 are fixed to the left end of the sheet paper feeding shaft 30 and the left end of the roller take-up shaft 32a of the press roller 32, respectively, and both transmission gears 42 and 43 can mesh with each other. It has become.

Therefore, when the sheet paper feed 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 the sheet paper roll R in the sheet paper roll storage part E, which will be described later, and then passed through the 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
The movable plate 50 is swingably disposed within the movable plate 50, and the front lower end of the swing arm 34, 35 of the suspension support frame 33 is swingably installed above the movable plate 50. The swing plate 51 is made up 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.

Further, reference numerals 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 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 something.

Then, put the sheet paper P on the toilet seat body 11. When feeding out the sheet paper, as shown in FIG. 4, the upper surface 50a of the movable plate 50 can be made substantially parallel to the upper surface of the inclined ceiling wall 22, and the sheet paper feeding path 8 can be formed above it.

Further, as will be described later, when cutting the sheet paper P, the movable plate 50 can be rotated around the pivot shaft 52.53 to take the rotational position shown in FIGS. 7 to 9. can. 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 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.

The swinging plate 51 has its sheet paper pressing portion 6
Pivot shafts 62.63 are provided protrudingly from both ends of the upper part 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 pressing piece 56 allows the sheet paper P to be ramped without slipping.

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 outer wall 2
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 draws a cam locus for an irregular shape, and the guide roller has a peripheral surface that comes into contact with the same peripheral surface. 70 moves up and down, and this up and down movement allows the movable plate 50 to swing around the pivot shafts 52 and 53, and in conjunction with the swinging of the movable plate 50, the swing plate 51 also swings. Thus, 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. At this time, the sheet paper P is fed out so that the cutting perforation 90 (see FIG. 3) is located approximately directly below the cutting blade 61a of the sheet paper cutter 1t161 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 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 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 gear 42.43, and the movable plate 50 and the swinging plate 51 are connected to the sheet paper through the sheet paper pressing piece 56.64. 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 is further rotated counterclockwise, and the swing plate 51 is also rotated 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 90.

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 on the sheet paper P and take the position shown in FIG. It is possible to effectively prevent splashed water from flowing into the sheet paper delivery path 8.

Note that since the sheet paper P is cut by applying tension and pressing force to the sheet paper P, the sheet paper cutting portion 61 of the swing plate 51 or its cutting blade 61a is formed of a sharp metal or the like. It is not necessary to do so, and it can also be formed of rounded ceramics, corrosion-resistant 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.

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

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

Next, the configuration of the sheet paper roll storage section E disposed on the casing body 16 including the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section 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 protective cover disposed on the casing main body 16 in a state surrounding the sheet paper roll R, and its front lower end is provided at the sheet paper outlet 85 to prevent the swinging of the hanging support frame 33. Arm 34.
A cup λ-holder installed between the lower end front parts of the casing body 16 is removably held and supported on a stop plate 86, and the rear lower end is attached to an extended rear wall 87 extending on the upper part of the rear wall 21 of the casing body 16. It is engaged and supported at the upper end.

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, in the unlikely event that the sheet paper P becomes clogged or entangled in the sheet paper delivery path 8, etc., causing trouble,
As shown in FIG. 11, after removing the sheet paper roll protection cover 84, the tangled sheet paper P can be easily removed by swinging the hanging support frame 33 forward.

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 has a non-perforated part 92 between its rear ends, so when the cutout perforation 91 is cut out, the cut out central part is It drips into the flush toilet bowl 10, and its lower end is 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 cutout perforations 91 is that 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 11. 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 a paper jam 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 FIG. 3 and the twelfth time, the sheet paper P has non-perforated portions 9 at regular intervals in the longitudinal direction.
2 and the tip of the cutout perforation 91, a position detection through hole 93 is provided, and a light emitting element is provided in the front part of the inclined ceiling wall 22 of the casing body 16 corresponding to the through hole 93. A position detection sensor 94 consisting of a light receiving element and a light receiving element is provided.

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

Note that instead of the through-holes 93, desired colored marks may be applied to the sheet paper P, and furthermore, the through-holes 93, etc., may be attached not only at the center of the sheet paper P but at any desired location. 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, 5 seconds) has elapsed, a detection signal is generated, the control unit F is activated, the rotation motor 75 is driven, and the clamp on the sheet paper P is released. At the same time, the movable plate 50 and the swing plate 51 can be moved from the position shown in FIG. 9 to the position shown in FIG. 10 so as to block the entry of dirty water into the sheet paper delivery path 8. That is, since the movable plate 50 operates to close the sheet paper outlet 85, it can function as a sewage intrusion barrier.

Note that the seating detection means 96 can be integrated into the automatic sheet paper supplying toilet seat A, or can be separated and made into a separate body, depending on the usage conditions and usage environment.

Furthermore, in addition to the above-mentioned infrared sensor and the like, 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, 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 external 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 described.

As shown in FIG. 5, a control unit mounting plate 100 is provided upright in a compartment 23b formed on one side of the casing body 16, and the above-mentioned rotation motor is mounted on the control unit mounting plate 100. A control panel 101 is attached to control the operations of 40, 75, etc., and forms a control section F. Note that a transformer 102 is also integrally attached to the control panel 101.

Next, the operation section G will be explained as shown in FIGS. 1 and 3.
As is most obvious from the figure, the operation section G includes a button 1035 for feeding sheet paper, a power lamp 104 consisting of a light emitting diode, etc., and a button 1035 for feeding sheet paper, a power lamp 104 for handling paper jams, paper replenishment, etc. It is constructed by attaching a paper supply lamp 1051, a paper trouble lamp 106, etc., which have a warning function in case 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 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 11o.

111, and a memory M that stores a sheet paper feeding/cutting order program to be described below.

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

The control section F is provided with a timer T1, which is activated when the sheet paper feeding button 103 is pressed for a predetermined period of time, for example, 5 seconds. This forms a reset means capable of resetting the device to its initial state.

In other words, the movable plate 50 is configured to be able to release the clamp of the sheet paper P and close the sheet paper outlet 85 as a barrier to sewage intrusion.

Therefore, with this reset means, the toilet seat main body 11
If the sheet 1~ paper that is fed out is twisted or wet, the sheet paper cutting mechanism can be reset to the initial state as described later to easily remove the sheet paper P from the toilet seat body. It can be removed and 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 having the above configuration
The operation will be explained with reference to flowchart 1 shown in FIGS. 14(A) to 14(B).

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

When using the flush toilet 10 in this state, 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 drive signal causes the rotation motor 75 of the sheet paper cutting mechanism section and the sheet paper feeding sequence to be activated. Mechanism part C
The rotary motors 40 are operated in sequence. Then, the movable plate 50 rotates counterclockwise due to the clockwise rotation of the disc cam 71 driven by the rotation motor 75, and takes the posture shown in FIG. 4 from the posture shown in FIG. 10. . That is, a sheet paper outlet 85 is provided on the movable plate 50.
A sheet paper delivery path 8 communicating with the paper is 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 control unit F is prevented from sending a drive signal to the rotation motor 4o (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 4° (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 4o to drive the rotary motor 40 (158), and the sheet paper P is fed out from the sheet paper roll R.

Also, when the rotation motor 40 starts driving, the timer T2
(Fig. 13) is activated (159). Then, the sheet paper P is fed out 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. Translucent 93 provided at P
is detected (159cY), the rotary motor 40 stops with the set length of sheet paper P being fed out (16cY).
0). 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 timer setting time t1 (159a
N) turns off the sheet paper feeding rotary motor 40 and turns on the paper trouble lamp 106 (1).
61).

Furthermore, even if sheet paper P is detected within the timer setting time tl, the next timer setting time t2 (rotation motor 40
(counting from the start of driving) (if the position detection sensor 94 detects the transmitted light 93, then (159bY),
Similarly, the rotation motor 40 is turned off, and the paper supply lamp 105 is turned on (162).

Furthermore, if the transmitted light 93 is not detected within the timer setting time t2 (159 cN), the rotation motor 4o is turned off and the paper trouble lamp 106 is turned on (163 cN).
). 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. 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
).

Furthermore, when the rotation motor 75 is driven by the drive signal from @control part F, the sheet paper cutting blade 61a of the sheet paper cutting section 61 of the swinging plate 51 is rotated 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 button 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 sheet paper P becoming entangled within 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.
A drive 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 5
1 will take the state shown in FIG.

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

After that, drive the cleaning device and wash the water! The inside of the sheet paper P can be washed, and the separated portion of the sheet paper P can be drawn in and flowed out together with the washing water and dirt by the force of the washing water.

In the above step, after the sheet paper P is cut and held by the cooperation of the movable plate 50 and the swing plate 51 (165), but before the sheet paper P is seated (169), someone forcibly cuts the sheet paper If the sheet 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 period of time (approximately 5 seconds) to remove it. If the user does not sit on the toilet seat main body ll within a predetermined period of time (168) for some reason, the sheet paper P is removed by each reset means independently of the seating detection means 96. 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, and releases the clamp on the sheet paper P. At the same time, the sheet paper feed path opening 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. There is no fear that the sheet paper P will fall from the toilet seat main body 11 even if the person moves his/her body slightly (so that the user can use the toilet comfortably.

Further, in the present invention, the control unit has the movable plate 50 that normally operates as a sewage intrusion barrier to close the sheet paper delivery port 85, and the sheet paper delivery button 10 to close the sheet paper delivery port 85.
Only when button 3 is pressed, the sewage intrusion barrier is released and the sheet paper outlet 85 is opened. Even if sewage is scattered during use,
It is possible to reliably prevent the dirty water from entering into the casing main body 16, and it is possible to reliably prevent breakdowns due to corrosion of functional parts within the casing main body 16, wetting of sheet paper rolls, etc.
