The device winds up or folds continuous sheet paper that is sized and shaped to cover the top surface of the toilet seat, and stores it in a sheet paper protective cover. A sheet paper roll holder configured to continuously feed out the sheet paper; It is equipped with a feed roller for sending it to the
The present invention is characterized by a structure consisting of a feeding cutting section for the sheet paper, which is equipped with a cutting blade for cutting the rear end of the fed sheet paper of a predetermined length.

In such conventional devices, sheet paper feeding and cutting operations are performed by pressing an operation button to rotate a feeding roller or by raising and lowering a cutting cutter.

(C) Problems to be Solved by the Invention However, in the conventional configuration described above, no safety measures are taken, and the sheet paper roll may be used up or the paper may get tangled inside the device and cause a paper jam. If the feeding roller or cutting cutter malfunctions when replenishing the roll or removing jammed paper, it may pose a danger to the user.To prevent this danger, it is necessary to It was a hassle to have to turn the power on and off.

(d) Means for solving the problem The present invention stores a sheet paper roll in a sheet paper protective cover disposed behind the toilet seat body, and transfers sheet paper from the sheet paper roll onto the top surface of the toilet seat body. An automatic sheet paper supply system comprising a sheet paper feeding mechanism for feeding, a sheet paper cutting mechanism for cutting the sheet paper after feeding, and a control section for controlling the sheet paper feeding mechanism and the sheet paper cutting mechanism. The toilet seat is provided with cover opening/closing detection means for the sheet paper protective cover, and when the means detects the opening operation of the sheet paper protective cover, it blocks the operation of the sheet paper feeding mechanism and the cutting mechanism, and prevents the cover from closing. An object of the present invention is to provide an automatic sheet paper supplying toilet seat characterized in that, when the sheet paper feeding mechanism section and the cutting mechanism section are detected, the sheet paper feeding mechanism section and the same cutting mechanism section are reset to the initial state.

Note that the initial state here refers to a state in which the toilet seat can start its normal operation starting from feeding out the sheet paper.

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

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 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.

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

Further, in FIGS. 4 and 5, reference numeral 33 denotes a suspension support that is U-shaped when viewed from the front and is composed of left and right swinging arms 34 and 35 and a connecting plate 36 that connects the lower ends of both arms 34 and 35. It is a frame, and the same suspension support frame 3

3 and 24 so as to be swingable.

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.
Line connecting 7, 38 and presser roller 32 (L1)
is inclined with respect to the perpendicular line (L2) extending downward from the cylindrical boss portions 37 and 38, so the press roller 32 is in pressure contact with the feeding roller 31 in the normal contact state. , 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 mounting shaft 32a of the presser roller 32, respectively, and both transmission gears 42 and 43 can mesh with each other.

Therefore, when the sheet paper feeding shaft 30 is rotated by the rotary motor 40, the feeding roller 3
1 and the press roller 32 are also rotated together via the same transmission gears 42 and 43.
Sheet paper P is fed out from a sheet paper roll R in a sheet paper roll storage section E, which will be described later, and then passed through a sheet paper delivery path 8 formed between the inclined ceiling wall 22 of the casing body 16 and the lower surface of the hanging support frame 33. , onto the toilet seat body 11.

Further, as will be described later, the sheet paper P is clamped between the feed roller 31 and the press roller 32, but in this case, both rollers 31 and 32 are engaged with each other by transmission gears 42 and 43. , as long as the 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 swingably disposed within a plate insertion space 22a provided at the front of the inclined ceiling wall 22 of the casing body 16, as shown in FIGS. 4 and 5. The movable plate 50 provided above and the swinging arms 34 and 35 of the suspension support frame 33 arranged above the movable plate 50
The swing plate 51 is swingably installed between the front lower ends of the swing plate 51.

First, to explain the configuration of the movable plate 50, as shown in FIGS. 4 and 5, the movable plate 50 is formed from a long and wide rectangular flat plate extending in the left-right direction, and has pivots at both ends. 5
2, 53 are provided protrudingly, and the same pivots 52, 53,
Left and right side walls 18 and 1 of the casing body 16, respectively.
It is rotatably supported on 9.

Moreover, 54 and 55 are biasing springs attached to the pivot shafts 52 and 53 in order to keep a guide roller 70, which will be described later, in constant contact with the disc cam 71.

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.

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

Furthermore, the swing plate 51 has a sheet paper pressing piece 64 made of an elastic material attached to the lower end of its sheet paper pressing part 60.
4 and the sheet paper pressing piece 56 of the movable plate 50, the sheet paper P can be clamped without slipping.

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

Next, 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 disposed in rotatable contact with the guide roller 70 and moves the guide roller 70 up and down by rotation, and a rotating shaft 72 to which the disc cam 71 is fixed is
Both ends of the rectangular mounting plate 1 of the casing body 16
It is rotatably supported by a pair of bearing stands 73 erected on 7. Moreover, one side extension part of the rotating shaft 72 passes through the left side wall 18 and connects to a compartment 23 formed between the sheet paper roll mounting wall 23 and the outer wall 23a.
b, and the extended portion is connected to the deceleration device 74.
It is interlocked and connected to the rotation motor 75 via.

With this configuration, when the rotation motor 75 is driven, the rotation shaft 72 rotates, and the disc cam 71 that is integral with the rotation shaft 72 also rotates about the axis of the rotation shaft 72. Since the center of the disc cam 71 is eccentric from the axis of the rotating shaft 72, the circumferential surface of the disc cam 71 draws a cam locus of an irregularly shaped circle, and the guide roller has a circumferential surface that comes into contact with the same circumferential surface. 70 moves up and down, and by this up and down movement, the movable plate 50 can be swung around the pivots 52 and 53, and in conjunction with the swiveling of the movable plate 50, the swiveling plate 51 can also be swung. By moving, the sheet paper P can be effectively cut in the manner described below.

First, in FIG. 4, the sheet paper P is fed out onto the toilet seat main body 11 through the sheet paper feeding path 8 by the rotation of the feeding roller 31 and press roller 32 driven by the sheet paper feeding mechanism section C mentioned above. It can be done. In addition, in that case,
Cutting perforation 90 provided in sheet paper P
(See FIG. 3) is fed out so that it is positioned substantially directly below the cutting blade 61a of the sheet paper cutting section 61 of the swing plate 51.

Next, the rotary motor 75 is driven to rotate the disc cam 7.
1 clockwise, the guide roller 70
The movable plate 50 rotates counterclockwise around the pivots 52 and 53 via the pivot plate 50, and as shown in FIG. Clamp P. Then, the portion of the sheet paper P located between the clamp portion and the clamp portion where the feeding roller 31 and the holding roller 32 come into contact is pressed and bent upward by the rear end of the movable plate 50, and tension is applied to the sheet paper P. Add.

As described above, the feeding roller 31 and the pressing roller 32 are engaged with each other through the transmission gears 42 and 43, and the movable plate 50 and the swinging plate 51 are 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.
Then, the sheet paper P after cutting is pressed by the pressing piece 5
6 and 64 continues.

Next, after the user sits down and relieves himself, the toilet seat body 1
1, the seating detection means 96, which will be described later, detects the movement, and the signal is sent to the control unit F.
When the sheet paper P is fed, the disc cam 71 further rotates clockwise, and the movable plate 50 rotates clockwise this time to release the clamp on the sheet paper P and assume the position shown in FIG. Splashed water during subsequent washing can be effectively prevented 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 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 with a straight line, but it can also be formed of rounded ceramics, corrosion-resistant and abrasion-resistant synthetic resin, or the like.

Therefore, even during long-term use, frequent replacement of the swing plate 51 due to corrosion or wear can be prevented, and maintenance can be improved.

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

Moreover, cutting performance can be improved by forming the cutting blade 61a into a chevron shape as shown in FIG.

Next, the configuration of the sheet paper roll storage section E disposed on the casing body 16 including the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section D will be described.

In FIGS. 4 and 5, reference numerals 80 and 81 indicate support rods fitted into the boss portions 37 and 38 of the suspension support frame 33, which are equipped with springs 82 inside. Both ends of a hollow roll core 83 having a roll R attached to its outer peripheral surface are inserted and constructed in a detachable manner.

Further, 84 is a sheet paper roll protective cover disposed on the casing main body 16 in a state surrounding the sheet paper roll R, and its front lower end is provided at the sheet paper outlet 85 to prevent the swinging of the hanging support frame 33. It is removably engaged with and supported on a cover receiving plate 86 installed between the front lower ends of the arms 34 and 35, and the rear lower end is attached to the casing body 1.
It is engaged and supported by the upper end of an extended rear wall 87 extending above the rear wall 21 of 6.

In addition, the above sheet paper roll protective cover 8
Both ends of the sheet paper roll mounting wall 23 are engaged with fitting grooves 88 and 89 recessed along the inner edge of the sheet paper roll mounting wall 23, as shown in FIGS. 5 and 11.

In addition, a protrusion 95 is provided on the rear inner surface of the protective cover 84.
A cover opening/closing detection means 9 such as a micro switch is provided on the inner surface of the upper edge of the extended rear wall 87.
8, and the same means 98 is turned on.
-OFF, the open/closed state of the cover 84 is detected and input to the interrupt terminal MI of the control section F, which will be described later, via the interrupt controller 99.

In addition, in the unlikely event that the sheet paper P becomes clogged or tangled in the sheet paper feed path 8, etc., causing trouble, remove the sheet paper roll protection cover 84 as shown in FIG. By swinging the frame 33 forward, the entangled sheet paper P can be easily removed.

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

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

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

In addition, sheet paper P has perforation 9 for cutting.
A cut-out perforation 91 with a shape that matches the inner shape of the toilet seat body 11 is provided in the center between 0 and 90, and by cutting out the sheet paper P along the cut-out perforation 91, washing An opening communicating with the interior of the toilet bowl 10 can be provided.

However, the cutout perforation 91 is not completely annular, and a non-perforated part 92 is formed between both ends of the rear part, so the cutout perforation 91 is not completely circular.
When 1 is cut out, the cut out central part will hang down inside the flush toilet bowl 10, and the lower end will be submerged in standing water.

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

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

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

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

The position detection sensor 94 detects the position detection through hole 93 when the sheet paper P has been unwound for a predetermined length from the sheet paper roll R.
is detected, the operation of the sheet paper feeding mechanism section C is stopped, and the sheet paper P is accurately delivered to the toilet seat main body 1.
It can be supplied and positioned on 1.

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

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

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

Further, in FIG. 1, reference numeral 96 denotes a seating detection means consisting of an infrared sensor or the like provided on the inner surface of the one side extension 25 of the casing main body 16. After the user is seated on the toilet seat main body 11, the seating detection means 96 is used for a certain period of time ( For example, when the user leaves the toilet seat main body 11 after 5 seconds have elapsed, a detection signal is generated, the control unit F is activated, the rotation motor 75 is driven, and the sheet paper P is unclamped. The movable plate 50 and the swing plate 51 can be moved from the position shown in FIG. 9 to the position shown in FIG. 10 so as to block the entry of dirty water into the sheet paper delivery path 8.

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

Furthermore, in addition to an infrared sensor or the like, the seating detection means 96 can also use a micro switch, a limit switch, or the like, or a load cell or the like that detects the load when the passenger is seated.

In addition, in FIG. 1, 97 is the toilet seat main body 11.
When the toilet seat main body 11 is in a state where it cannot be seated (when the toilet seat main body 11 stands on its own), the detection is removed from the toilet seat main body 11. This is an abnormal delivery prevention sensor for stopping the supply, and the toilet seat body 11
The toilet seat main body 11 is detected only when the toilet seat body 11 is in a seatable state, and the toilet seat main body 11 is made operable.

It should be noted that a micro switch, a limit switch, or the like may be used as the abnormal delivery prevention sensor 97 instead of a normal sensor.

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

As shown in FIG. 5, a control unit mounting plate 1
A control board 101 for controlling the operation of the rotation motors 40, 75, etc. described above is attached to the control unit mounting plate 100, forming a control unit F.

Next, the operation section G will be explained.As is most obvious from FIGS. 1 and 3, the operation section G
A power switch 102, a push button 103 for feeding sheet paper, a power lamp 104 consisting of a light emitting diode, etc. are installed on one side extension 25 of the casing body 16, and a warning in case of an abnormality such as a paper jam or paper replenishment occurs. A paper supply lamp 105 having a function,
It is constructed by attaching a paper trouble lamp 106 and the like.

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

Further, FIG. 13 shows the configuration of a control device that controls the operation of the automatic sheet paper supplying toilet seat A.

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

The control sequence shown in the flowcharts of FIGS. 14A to 14C is programmed in the control section F, and in particular, when the sheet paper feeding push button 103 is pressed during the program, the sheet paper feeding mechanism Even after the sheet paper P is fed out onto the upper surface of the toilet seat body 11 in the section C and the paper P is cut in the sheet paper cutting mechanism section D, the paper P is continued to be clamped by the sheet paper pressing pieces 56 and 64, and the seating detection means 96 Once a signal detecting a seated human body is inputted, the pressing operation of the pressing pieces 56 and 64 is continued until the signal is no longer inputted, and the clamp is released after the signal turns OFF. ing.

Therefore, the sheet paper P does not shift while the user is seated or wrap around the buttocks when the user stands up after using the toilet.

Further, the control section F is provided with a timer function that is activated at the same time as the clamping operation of the sheet paper cutting mechanism section D and outputs an output if the seating detection means 96 does not detect seating even after a preset certain period of time has elapsed. , This output causes the sheet paper pressing pieces 56 and 64 to be unclamped.

Therefore, even if the sheet paper P is fed out, clamped and cut, and the clamp is still held, the clamp is automatically released, so that the next user can set it on the toilet seat body 11. The sheet paper P can be discarded and a new sheet paper P can be fed out and used.

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

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

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

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.
50 control section F and each operating section are initialized.

Furthermore, even if the operation of the sheet paper feeding mechanism C or the cutting mechanism D stops midway due to a power outage, etc., and the state shown in Fig. 10 is not established, when the power is turned on, the control unit F When the power-on reset is performed, that is, initialization is performed, the sheet paper feeding mechanism section C and the cutting mechanism section D are at the starting position of operation (the state shown in FIG. 10), and the power lamp 104 is turned on.

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 driven to feed out the sheet paper P from the sheet paper roll R (158).

Furthermore, even if the user is sitting on the toilet seat main body 11 with the sheet paper P not being fed out, it is not preferable for the user to pay out the sheet paper P onto the toilet seat main body 11. Activated, the control unit F prevents the drive signal from being sent to the rotation motor 40 (154).

Further, since it is not preferable to feed out the sheet paper P onto the toilet seat body 11 when the toilet seat body 11 is standing, the abnormal feeding prevention sensor 97 detects that the toilet seat body 11 is in the upright state, and the control unit F The drive signal is not sent to the rotation motor 40 (155).

Furthermore, even when the position detection sensor 94 that also serves as paper detection located inside the casing body 16 detects that the sheet paper P is present in the sheet paper delivery path 8 inside the casing body 16, For feeding, the casing body 16
Since this would cause the sheet paper P to get entangled in the rotation motor 40, the control unit F prevents the drive signal from being sent to the rotation motor 40 based on the detection output (156).

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

Further, the timer (T2) (FIG. 13) is activated when the rotation motor 40 starts driving (159). Then, the sheet paper P is fed onto the toilet seat main body 11, and then the position detection sensor 94 detects the sheet paper P normally, that is, within the timer setting time (t1), and at the same time, the position detection sensor 94 detects the sheet paper P normally, that is, within the timer setting time (t2). When the through hole 93 provided in the sheet paper P is detected inside (159cY), the rotary motor 40 stops with the sheet paper P fed out for the set length (160). At this point, sheet paper P
The cutting perforation 90 located at the rear end is located approximately directly below the sheet paper cutting blade 61a of the swing plate 51.

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

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

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

Next, 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 When the feeding roller 31 and the holding roller 32 are also clamped, and then the rotary motor 75 continues to rotate in response to continuous drive signals from the control unit F, the portion of the sheet paper P located between the two clamped portions is fed out. A directional tension will be added (164).

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

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

After that, 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). Even if the button is pressed, as long as the seating detection means 96 detects the detection, control is performed so that the drive signal is not sent 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 accidents such as entanglement of the sheet paper P within the casing body 16. can be reliably prevented.

Then, when the user leaves the toilet seat main body 11 after using the toilet (172), the seating detection means 96 is turned off (173), and based on the OFF signal, the control unit F sends a drive signal to the rotation motor 75 again. is sent to rotate the rotary motor 75. With this, the movable plate 5
0 and the swing plate 51 will assume the state shown in FIG.

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

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

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 the sheet paper P is forcibly pulled out before sitting 169 (166), or if the sheet paper P stretched out onto the toilet seat body 11 is wet,
If the sheet paper feeding push button 103 is held down for a predetermined period of time (approximately 5 seconds) to eliminate this problem (167), if for some reason the user sits on the toilet seat main body 11 within the set period of time (167). If not (168), the controller F sends a drive signal to the rotary motor 75 to discard the sheet paper P as unusable, regardless of the seating detection means 96, and causes the movable plate 50 and the swing plate 51 to ,
Put the sheet paper P into the state shown in Figure 10.
At the same time, the sheet paper outlet 85 can be closed (174) (175).

During the above operation, if the sheet paper roll protective cover 84 is removed to clear a paper jam or replenish the sheet paper roll R, the cover opening/closing detection means 98 is activated and the output of the means 98 is set to low level. When the cover 84 is attached again after removing the paper jam or replenishing the sheet paper roll R, the output of the means 98 becomes high level, so the output is sent to the interrupt terminal of the control unit F by the interrupt controller 99. By inputting it into MI,
No matter what operating state the device is in, the 14th
The routine from flowchart C in Figure c can be executed. In addition, at this time,
A single sheet of sheet paper P is delivered onto the toilet seat body 11 and cut, but if the flush toilet 10 is not used immediately, the paper can be discarded.

Although it is conceivable that the user may remove the protective cover 84 while the user is seated, in order to prohibit the above operation, the interrupt terminal MI is All you have to do is program it to mask it.

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

When the sheet paper protective cover 84 is opened, the control unit F immediately stops all functions of the device, so maintenance such as replenishing the sheet paper roll R and removing paper jams can be safely performed. When the sheet paper roll protection cover 84 is attached after the process is finished, it is automatically reset and can be used immediately, which has the effect of simplifying operation and handling.

Note that only when the closed state output of the cover opening/closing detection means 98 of the sheet paper roll protective cover 84 is ANDed with the ON of the power switch 102,
If the power is turned on, the device will be reset on power, and the same effect as above can be obtained.
