Abstract

PURPOSE:To prevent fingers from accidents such as being caught in and injured and facilitate the handling of a stool by blocking the operations of a seat paper drawing mechanism and a seat paper cutting mechanism when a cover opening/ closing detecting means detects the opening operation of a cover and resetting the operations to the initial condition when said means detects the closing operation. CONSTITUTION:Rotary motors 75, 40 of a seat paper cutting mechanism D and sheet paper drawing mechanism C are operated sequentially by drive signals from a controller. When a seat paper roll protecting cover 84 is removed, a cover opening/closing detecting means 98 is operated to set the output thereof to a low level and, when said cover 84 is mounted, set the output thereof to a high level. Since the controller stops all functions of device as soon as the cover 84 is opened, maintenance such as replenishment of a seat paper roll R and the elimination of paper jam can be safely carried out. When the cover 84 is mounted, the device is automatically reset to be immediately used, so that the operation and handling are simplified.

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

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

In this embodiment, the sheet paper cutting mechanism section (D) is connected to the casing body (16) as shown in FIGS. 4 and 5.
A movable plate (50) is swingably disposed in a plate insertion space (22a) provided at the front of the inclined ceiling wall (22)
) and a swinging plate ( 51).

First, the configuration of the movable plate (50) will be explained. As shown in FIGS. 4 and 5, the movable plate (50)
) is formed from a long and wide rectangular flat plate extending in the left-right direction, and has pivots (52053) protruding from both ends, and the pivots (52053) are attached to the left and right sides of the casing body (16), respectively. It is rotatably supported on the side walls (18) and (19).

In addition, (54) and (55) are the guide rollers (
70) is a biasing spring attached to the pivot shafts (52) and (53) in order to keep the disc cam (71) in constant contact with the disc cam (71).

Further, (56) is a sheet paper pressing piece made of an elastic material, which is provided at the rear of the upper surface (50a) of the movable plate (50) and cooperates with the sheet paper pressing piece (64) of the swinging plate (51), which will be described later. Then, the sheet paper (P) is clamped.

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

In addition, as will be described later, when cutting the sheet paper (P), the movable plate (50) is rotated with the pivots (52) (53).
) to assume the rotational positions shown in FIGS. 7-9. Furthermore, when the toilet seat is not in use, the movable plate (50) can be made to take the rotational position shown in FIG. 10.

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

As shown in FIG. 4, the swing play (51) is formed of a thick sheet paper pressing part (60) and a thin sheet paper cutting part (61) in a side view, It has an open U-shaped cross section.

This swing plate (51) has pivots (62) and (63) protruding from both ends of the upper part of the sheet paper press g-(eo), and both pivots (62063) are connected to the hanging support frame (33).
) is rotatably supported at the front lower end of the left and right swing arms (34) and (35).

Furthermore, the swinging plate (51) has a sheet paper pressing piece (64) made of an elastic material attached to the lower end of its sheet paper pressing part (60), and the pressing piece (64) and the movable plate (50) are connected to each other. Sheet paper pressing piece (5
6) allows the sheet paper (P) to be clamped without slipping.

In addition, return springs (65) (66) are attached to the pivots (62) (63), respectively, and the springs (65) (66) keep the swing plate (51) at all times as shown in FIG. It is rotated counterclockwise and cooperates with stoppers (67) (68) protruding from the inner surfaces of the sheet paper roll mounting walls (23) (24) to move to the standby position shown in FIG. The swing plate (51) can be held such that the sheet paper cutting section (61) is in a position retracted from the sheet paper delivery path (8).

Next, the movable plate (50) and the swing plate (5
Although various types of drive mechanism for the sheet paper cutting R top part (0) consisting of (1) and (0) can be considered, in this embodiment, it is constructed as shown in FIGS. 4 to 6.

That is, the guide roller (70) is attached to the movable plate (50) at a position eccentric to the rear from the pivot (52053) at its lower part. The lower part of the guide roller (70) is in rotatable contact with the guide roller (70), and by rotation, the guide roller f70)
A rotating shaft (72) to which the disc cam (71) is fixed has both ends mounted on the rectangular mounting plate (17) of the casing body (16). It is rotatably supported by a pair of bearing stands (73) installed upright. In addition, the extension portion of the rotating shaft (72) is located on the left side wall (
The sheet paper roll mounting wall (23) is inserted through the sheet paper roll mounting wall (23).
) and the outer wall (23a) into the closed chamber (23b), and the extension part is connected to the
It is operatively connected to a rotation motor (75).

With this configuration, when the rotary motor (75) is driven, the rotary shaft (72) rotates, and the disc cam (71) that is integrated with the rotary shaft (72) also rotates about the axis of the rotary shaft (72). It will rotate as. However, the disk cam (7
Since the center of 1) is relative to 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 (
70) moves up and down, and this up and down movement allows the movable plate (50) to swing around the pivots (52) and (53), and in conjunction with the swinging of the movable plate (50), The swing play) (51) also swings to effectively cut the sheet paper (P) in the manner described below.

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

Next, the rotary motor (75) is driven to rotate the disc cam (71).
) is rotated clockwise, the movable plate (50) is rotated counterclockwise about the pivots (52) and (53) via the guide roller (70), and as shown in FIG. The paper pressing piece (56) is connected to the swing plate (
Clamp the sheet paper (P) together with the sheet paper pressing piece (64) of 51). The same clamp part, the feeding roller (31) and the holding roller (32)
) is pressed and bent upward by the rear end of the movable plate (50) to apply tension to the sheet paper (P), which is located between the clamp portion and the clamp portion in contact with the movable plate (50).

In addition, as mentioned above, the feed roller (31) and the press roller (32) are engaged by the transmission gear (42043), and the movable plate (50) and the swing plate (51) are used to press the sheet paper. Piece (56) (64)
Since the sheet paper (P) is clamped through the clamp, slippage at the clamp portion can be reliably prevented.

Thereafter, when the disc cam (71) is further rotated clockwise, the movable plate (50) further rotates counterclockwise as shown in FIG. (51) will be rotated clockwise. Therefore, the cutting blade (61a) provided at the tip of the sheet paper cutting portion (61) of the swing plate (51) further applies tension while pressing the sheet paper (P) downward.

Further, as shown in FIG. 9, if the disc cam (71) is rotated clockwise, the movable plate (50) further rotates counterclockwise, and the swing plate (51) rotates clockwise. By the same rotation, the swing plate (51)
The cutting blade (61a) of the sheet paper cutting unit (61) further presses the sheet paper (P) downward to apply tension, and as a result, the sheet paper [P] is cut from the perforation (90). It turns out. The sheet paper (P) after cutting continues to be clamped by the pressing piece (56064).

Next, when the user sits down and leaves the toilet seat body (11) after relieving himself, the seating detection means (96), which will be described later, detects the movement and sends a signal to the control unit (F). , 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 release the 10th sheet paper (P).
By taking the position shown in the figure, it is possible to effectively prevent splashed water during washing after using the toilet from flowing into the sheet paper delivery path (8).

In addition, since the sheet paper (P) is cut by applying tension and pressing force to the sheet paper (P), the sheet paper cutting part (61) of the swing plate (51) or its cutting blade is used to cut the sheet paper (P). (61a) need not be formed from a sharp metal or the like, but may also be formed from a rounded ceramic, a 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 gauging main body (16) including the sheet paper feeding mechanism section (C) and the sheet paper cutting mechanism section (D) will be explained.

In FIGS. 4 and 5, (80) < 81) is a support rod fitted into the boss part (37038) of the suspension frame (33), which is equipped with a spring (82) inside.
80) By (81), both ends of a hollow roll core (83) having a sheet paper roll (R) attached to its outer peripheral surface are removably inserted and constructed.

Further, (84) is a sheet paper roll protective cover disposed on the casing body (16) in a state surrounding the sheet paper roll (R), and its front lower end is located at the sheet paper outlet (85). Hanging support frame (33
) The cover holder installed between the front lower ends of the swing arms (34) and (35) is removably engaged and supported on the stop plate (86), and the rear lower end is connected to the rear wall of the casing body (16). (
21) is engaged with and supported by the upper end of an extended rear wall (87).

In addition, both rpA@ of the sheet paper roll protective cover (84) have fitting grooves recessed along the inner edge of the sheet paper roll mounting wall (23), as shown in FIGS. 5 and 11. (88) and (89) are engaged.

In addition, there is a protrusion (95) on the rear inner surface of the protective cover (84).
is provided protrudingly so as to be able to come into contact with a cover opening/closing detection means (98) such as a microswitch arranged on the inner surface of the upper edge of the extended rear wall (87), and the 0N- OF
F detects the open/closed state of the cover (84) and controls the control section (F) via the interrupt controller (99), which will be described later.
) is input to the interrupt terminal (Ml).

In addition, in the unlikely event that the sheet paper (P) becomes jammed or entangled in the sheet paper feed path (8), etc., causing trouble, remove the sheet paper roll protection cover (84) as shown in Figure 11. After that, by swinging the hanging support frame (33) forward, the entangled sheet paper (P) can be easily removed.

Next, the sheet paper (P) used in this example will be explained. As shown in FIGS. 4 and 5, the sheet paper (P) forms a part of the sheet paper roll (R). , to be used after cutting.

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

In addition, as shown in Figures 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. ,
The sheet paper (P) will be cut along the perforations (90).

In addition, the sheet paper (P) has perforations for cutting (90
) (90) is provided with a cutout perforation (91) that matches the inner shape of the toilet seat body (11), and the sheet paper (90) is cut out along the cutout perforation (91). By cutting out the flush toilet (1)
An opening communicating with the interior of 0) can be provided.

However, the cut-out perforation (91) is not completely annular, and a non-perforated part (92) is formed between both ends of the rear part, so when the cut-out perforation (91) is cut out, The cut central portion will hang down into the flush toilet bowl (10), and its lower end will be submerged in standing water.

In addition, the sheet paper (P) is not completely perforated, and the non-perforated part (92) and the cutout perforation (91)
) is provided because if it is made with a hole, there will be no waist,
This is because when the sheet paper (P) is fed onto the toilet seat body (11), it is bent and it is almost impossible to form a sheet paper roll (R).

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

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

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

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

Then, the position detection sensor (94) detects the position detection through hole (93) when the sheet paper (P) is paid out a predetermined length from the sheet paper roll (R), and the sheet paper is fed out. It is possible to stop the operation of the mechanism part (C) and accurately supply and position the sheet paper (P) on the toilet seat body (11).

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

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

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

In addition, in Fig. 1, (96) is the gauging body (1
6) is a seating detection means consisting of an infrared sensor, etc. provided on the inner surface of the - side extension part (25), and the seating detection means is composed of an infrared sensor etc.
1) When the user leaves the toilet seat body (11) after a certain period of time (for example, 5 seconds) after sitting on the toilet seat, a detection signal is generated, the control unit (F) is activated, and the rotating motor ( 75
), the movable plate (50) and the swing plate (51) are driven to release the clamp on the sheet paper (P) and to block the entry of dirty water into the sheet paper delivery path (8). The position can be moved from the posture shown in FIG. 9 to the posture shown in FIG.

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

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

In addition, in FIG. 1, (97) is detected when the toilet seat body (11) is in a state where it cannot be seated (toilet seat ratio t4 (when (11) is independent), and the detection is removed from the toilet seat body (11). This is an abnormal exposure prevention sensor that cuts off the power to the rotation motor (40) and stops the supply of sheet paper (P) via the control unit (F), so that the toilet seat body (11) can be seated. The toilet seat main body (11) is detected only when it is in a safe state and is made operable.

In addition, a microswitch, a limit switch, etc. can also be used for the abnormal delivery prevention sensor (97) instead of a normal sensor.

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

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

Next, the operation part (G) will be explained. As is most obvious from FIGS. (102) , push button for feeding sheet paper (
103), a power lamp (1) consisting of a light emitting diode, etc.
04) and a paper replenishment lamp (105) that has a warning function in the event of an abnormality such as a paper jam or paper replenishment.

It is constructed by attaching a paper trouble lamp (106), etc.

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

Also, Figure 13 shows a toilet seat with automatic sheet paper supply (^)
The configuration of the control device that controls the operation of is shown.

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

The control section (F) has the following functions:
) is programmed, and in particular, when the sheet paper feeding push button 1103) is pressed during the program, the sheet paper feeding mechanism (C) feeds the sheet paper (P) to the toilet seat body (1103). ), and even after the paper (P) is cut by the sheet paper cutting mechanism (D), the sheet paper pressing pieces (56) and (64) continue to clamp the paper (P), and the seating detection means ( 96), a signal detecting a seated human body is input, then the pressing operation of the pressing pieces (56) and (64) is continued until the signal is no longer input, and after the signal turns OFF, the same pressing operation is performed. I'm trying to cancel the rung.

Therefore, the sheet paper (P) does not slip while sitting or cling to the buttocks when standing up after using the toilet.

The control unit (F) also includes a sheet paper cutting mechanism unit (
A timer function is provided that starts at the same time as the clamping operation of step 0) and outputs an output if the seating detection means (96) does not detect seating even after a preset period of time has elapsed. The clamps of the pieces (56) and (64) are released.

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 the next user can set it on the toilet seat body (11). The sheet paper that had been
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 activated by the output from the seating detection means (96) after the sheet paper (P) is fed out a predetermined length. As long as the sheet paper (P) is being sent to the control section (F), the sheet paper (P) is not fed out even if the sheet paper feeding push button (103) is pressed.

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

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

Below, the sheet paper automatic supply toilet seat with the above configuration (
Regarding the operation of ^), Figure 14 (^) to Figure 14 (C)
This will be explained with reference to the flowchart shown in .

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

In this state, when using the flush toilet (10) now, as shown in Fig. 3, when the power switch (102) provided on the side of the casing body (16) is turned on (150), the control unit (F) And each operating section is initialized.

In addition, due to a power outage, etc., the sheet paper feeding mechanism (C
) or the cutting mechanism section (D) stops midway and is not in the state shown in Figure 10, when the power is turned on, the control section (F) is power-on reset, that is, initialized. Then, the sheet paper feeding mechanism (C) and the cutting mechanism (0) reach the starting position of operation (the state shown in Fig. 10), and the power lamp (104) lights up (151).
.

Next, when the sheet paper feeding push button (103) is pressed (152), the rotation motor (7) of the sheet paper cutting mechanism (D) is activated by the drive signal from the control section (F).
5) and the rotating motor of the sheet paper feeding mechanism (C) (
40) are activated in sequence. 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 tenth
The posture shown in the figure changes to the posture 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 unwind the sheet paper (P) from the sheet paper roll (R) (158).

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

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

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

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

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

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

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

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

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

Then, the rotation motor (75) is restarted by the drive signal from the control section (F), and as shown in FIGS. 7 and 8,
Press the sheet paper (P) with the sheet vapor pressing piece (56
) (64) and the feeding roller (3
1) and the presser roller (32), and then, when the rotation motor (75) continues to rotate due to continuous drive signals from the control unit (F), the sheet paper ( Tension in the feeding direction is applied to the portion P) (164).

Furthermore, the rotation motor (
75) is driven, the sheet paper cutting blade (61a) of the sheet paper cutting section (61) of the swing plate (51) cuts the sheet paper (P) as shown in FIG.
The sheet paper (P) is reliably cut by pressing along the cutting perforations (90) and 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 body (11) (1
69) The seating detection means (96) detects the seating 170), and based on the detection output, the control unit (F)
After that, even if the sheet paper feeding push button (103) is pressed, 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 while seated,
Since the sheet paper (P) is not fed out, accidents such as entanglement of the sheet paper (P) within the gauging body (16) can be reliably prevented.

When the user leaves the toilet seat body (11) after using the toilet (172), the seating detection means (96) is turned off (173), and based on the OFF signal, the control section (F) rotates. A drive signal is sent to the motor (75) again to rotate the rotary motor (75). As a result, the movable plate (50) and the swing plate (51) assume the state shown in FIG. 10.

That is, while the clamp of the sheet paper (P) is released, the movable plate (50) is moved to the sheet vapor outlet (
sewage sheet vapor delivery path (8) through (85);
(174) (17
5).

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

In addition, in the above step, after the sheet paper (P) is cut and held (165) by the cooperation of the movable plate (50) and the swinging plate (51), and before the sheet paper (P) is seated (169), the forced When the sheet paper (P) is pulled out (166) or the toilet seat body (11)
The sheet paper (P) that is fed out on top becomes wet,
If the sheet paper feeding push button (103) is held down for a predetermined period of time (approximately 5 seconds) (167) in order to eliminate this problem, if for some reason the user presses the toilet seat main body (11) again within the set time. If you do not sit on (
168), the control unit (168) is configured to discard the sheet paper CP) as unusable, regardless of the e-seat detection means (96).
F) sends a drive signal to the rotating motor (75), and the movable plate (50) and the swinging plate (51)
The state shown in the figure is taken, the sheet paper (P) is unclamped, and the sheet paper outlet (85) is opened.
can be closed (174) (175).

During the above operations, clearing paper jams, sheet paper rolls (
When the sheet paper roll protective cover (84) is removed to replenish paper roll R), the cover opening/closing detection means (
98) is activated, the output of the same means (98) becomes low level, and the paper jam is cleared or the sheet paper roll (R) is activated.
When the cover (84) is reinstalled after replenishing the supply, the output of the means (98) becomes high level, so the output is sent to the interrupt terminal (old) of the control unit (F) using the interrupt controller (99). No matter what operating state the device is in, the flowchart in Figure 14C (
The routine from C) can be executed.

At this time, the - batch of sheet paper CP) is fed out onto the toilet seat body (11) and cut, but it is immediately removed from the toilet seat body (11).
10) If you are not only using the vapor, you can discard it.

Although it is possible that the user removes the protective cover (84) while seated, the control section (F) receives a seating signal from the seating detection means (96) in order to prohibit the above operation. All you have to do is program it to mask the interrupt terminal (old).

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

When the sheet paper protection 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 clearing paper jams can be performed safely. Furthermore, when the sheet paper roll protection cover (84) is attached after the above-mentioned maintenance is completed, it is automatically reset and can be used immediately, which has the effect of facilitating operation and handling.

In addition, the closed state output of the sheet paper roll protective cover (84) and the cover opening/closing detection means (98) and the power switch (
If the power is turned on only when the AND with 102) is established, the device is reset on power, and the same effect as described above can be obtained.
