Then, the sheet paper (P) is clamped.

Then, when feeding the sheet paper (P) onto the toilet seat body (11), as shown in FIG. 4, the upper surface (50a) of the movable plate (50) is substantially parallel to the upper surface of the inclined ceiling wall (22). Thus, a sheet paper delivery path (8) can be formed above the sheet paper delivery path (8).

As will be described later, when cutting the sheet paper (P), the movable plate (50) is rotated around the pivots (52) and (53) so that the rotational position shown in FIGS. Can be taken. Further, when the toilet seat is not used, the movable plate (50) can be set to the rotational position shown in FIG.

Next, the structure of the swinging plate (51) for cutting the sheet paper (P) in cooperation with the movable plate (50) will be described.

As shown in FIG. 4, the swing plate (51) is formed from a thick sheet paper pressing portion (60) and a thin sheet paper cutting portion (61) in a side view, and is opened downward. It has a U-shaped cross section.

The pivot plate (51) has pivots (62) and (63) projecting from both upper ends of the sheet paper pressing portion (60), and the pivots (62) and (63) are connected to the suspension frame ( The left and right swing arms (34) and (35) of 33) are pivotally supported at the lower front end.

The rotating shaft (72) to which (1) is fixed is rotatably supported by a pair of bearing stands (73) whose both ends are erected on a rectangular mounting plate (17) of the casing body (16). One side extension of the rotation shaft (72) extends through the left side wall (18) and extends into the compartment (23b) formed between the sheet paper roll mounting wall (23) and the outer wall (23a). The extension is interlocked with a rotation motor (75) via a speed reducer (74).

With this configuration, when the rotation motor (75) is driven, the rotation shaft (72) rotates, and the disc cam (71) integrated with the rotation shaft (72) also rotates about the axis of the rotation shaft (72). Will rotate as. Since the center of the disk cam (71) is eccentric from the axis of the rotating shaft (72), the peripheral surface of the disk cam (71) draws a cam trajectory of an irregularly shaped circle and comes into contact with the peripheral surface. The guide roller (70) having a peripheral surface moves up and down, and by this up and down movement, the movable plate (50) can be swung about the pivots (52) and (53). In conjunction with the swing, the swing plate (51) also swings, so that the sheet paper (P) can be effectively cut in the manner described below.

First, in FIG. 4, the sheet paper (P) passes through the sheet paper delivery path (8) by the rotation of the feeding roller (31) and the pressing roller (32) driven by the above-mentioned sheet paper feeding mechanism (C). It is paid out on the toilet seat body (11). After that, a perforation (90) for cutting provided on the sheet paper (P) (see FIG. 3)

As described above, the feeding roller (31) and the pressing roller (32) are engaged by the transmission gears (42) and (43), and the movable plate (50) and the swing plate (51) are Since the sheet paper (P) is clamped via the paper pressing pieces (56) and (64), slip at the clamp portion can be reliably prevented.

Thereafter, if the disk cam (71) is further rotated clockwise, the movable plate (50) further rotates counterclockwise as shown in FIG. (51) will be rotated clockwise. Therefore, the sheet paper cutting section (6
The cutting blade (61a) provided at the tip of 1) further applies tension while pressing the sheet paper (P) downward.

Further, when the disk cam (71) is rotated clockwise as shown in FIG. 9, the movable plate (50) further rotates counterclockwise and the swing plate (51) rotates clockwise. Then, by the same rotation, the cutting blade (61a) of the sheet paper cutting portion (61) of the swing plate (51) further presses the sheet paper (P) downward to apply tension,
As a result, the sheet paper (P) is cut from the perforations (90). Then, the cut sheet paper (P) continues to be clamped by the pressing pieces (56) and (64).

Then, when the user separates from the toilet seat body (11), the separating operation is detected by seating detection means (96) described later, and when the signal is sent to the control unit (F), the disc cam ( Rotate 71) clockwise to move the movable plate (50)
Will rotate clockwise in the future, release the clamp of the sheet paper (P) and take the position shown in Fig. 10,

In the non-energized state, the movable plate (50) in the casing body (16) closes the sheet paper outlet (85) at one end as shown in FIG. (85) from entering the sheet paper delivery path (8).

In this state, when using the flush toilet (10), when the power switch (S) provided on the back surface of the casing body (16) is turned on as shown in FIG. 3 (150), the power lamp (104) ) Lights up (151).

Next, when the sheet paper feeding push button (103) is pressed (152), an operation start signal is input to the control unit (F), and the sheet paper feeding / reading read from the memory (M) is performed.
The control unit (F) generates a drive signal based on the cutting order program, and the drive signal causes the rotation motor (75) of the sheet paper cutting mechanism (D) and the rotation of the sheet paper unwinding mechanism (C) to rotate. The dynamic motor (40) operates sequentially. Then, the movable plate (50) rotates counterclockwise by the clockwise rotation of the disc cam (71) driven by the rotation motor (75), and the posture shown in FIG. 10 is changed to the posture shown in FIG. You will take a posture. 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, and the sheet paper (P) is paid out from the sheet paper roll (R) (158).

However, when the sheet paper roll protective cover (84) is not mounted on the casing body (16), the cover open / close detection means (98) is in the OFF state, so the push button (103) for feeding out the sheet paper must be pressed. Even if you press (15
2) Under the control of the control unit (F), the drive signal from the control unit (F) is not sent to the rotating motor (40) (153N), and the safety of operation can be ensured.

Also, when the user is seated on the toilet seat body (11) in a state where the sheet paper (P) is not extended, it is preferable to extend the sheet paper (P) onto the toilet seat body (11). Therefore, the seat detection means (96) is operated to prevent the drive signal from being sent to the control section (F) to the rotation motor (40) (154N).

Further, it is not preferable to feed the sheet paper (P) to the toilet seat body (11) when the toilet seat body (11) is standing.
Is detected to be in the standing state, and the control unit (F) is prevented from sending a drive signal to the rotation motor (40) (154N).

Further, the presence of the sheet paper (P) in the sheet paper delivery path (8) in the functional unit casing (15) is confirmed by the position detection sensor (94) also serving as paper detection disposed in the functional unit casing (15). Even when the detection is detected, the feeding of the sheet paper (P) causes the sheet paper (P) to be entangled with the functional unit casing (15), and the drive signal is rotated to the control unit (F) by the detection output. Motor (4
0). (156).

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

In addition, the timer circuit (T) (FIG. 13) operates at the same time as the start of driving of the rotation motor (40) (159). Then, the sheet paper (P) is fed out onto the toilet seat body (11),
Thereafter, the position detection sensor (94) detects the sheet paper (P) normally, that is, within the set time (t1), and the sheet paper (P) provided on the sheet paper (P) within the set feeding time (t2). When the hole (93) is detected (159cY), the rotating motor (40) stops in a state where the set length sheet paper (P) is fed out onto the toilet seat body (11) (160). At this point, the cutting perforation (90) located at the rear end of the sheet paper (P) is located substantially directly below the sheet paper cutting blade (61a) of the swing plate (51).

However, when there is an abnormality in the detection of the position detection sensor (94), that is, when the position detection sensor (94) does not detect the sheet paper (P) at the set time (t1) (159a).
N) turns off the sheet paper feeding rotation motor (40) and turns on the paper trouble lamp (160) (1).
61).

Also, even if the sheet paper (P) is detected within the set time (t1), the position detection sensor (94) is earlier than the next timer set time (t2) (counting from the start of driving of the rotating motor (40)). ) Detects the through hole (93), (159b
Y) turns off the rotation motor (40) as well,
The paper supply lamp (105) is turned on (162).

Further, when the through hole (93) is not detected within the set feeding time (t2) (159cN), the turning motor (40) is turned off and the paper trouble lamp (106) is turned on (16).
3). Then, after that, the user can take necessary measures such as refilling and checking paper.

Next, the rotation motor (75) is restarted by the drive signal from the control unit (F), and as shown in FIGS. 7 and 8,
Insert the sheet paper (P) into the sheet paper pressing piece (56)
(64) and between the feeding roller (31) and the pressing roller (32), and then the rotating motor (7) is driven by a continuous drive signal from the control unit (F).
When 5) is continued to be driven, tension in the feeding direction is applied to the portion of the sheet paper (P) located between the two clamp portions (164).

Further, when the rotation motor (75) is driven by a drive signal from the control section (F), as shown in FIG. 9, the sheet paper cutting blade (61a) of the sheet paper cutting section (61) of the swing plate (51). However, the sheet paper (P) is pressed along the cutting perforations (90), and the sheet paper (P) is surely broken, that is, 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).

Then, when the user sits on the toilet seat body (11) (16
9), the seat detection means (96) detects that
0), the control unit (F) receives the detection output, and even if the push button (103) for feeding out the sheet paper is pressed, the control unit (F) detects the detection and the rotation is performed as long as the detection output is generated. Control is performed so as not to send a drive signal to the motor (40) (171).

Therefore, even if the user presses the sheet paper feeding push button (103) by mistake or mischief while sitting,
Since the sheet paper (P) is not fed, an accident such as entanglement of the sheet paper (P) in the functional unit casing (15) can be reliably prevented.

Then, after the stool, when the user separates from the toilet seat body (11) (172), the seat detection means (96) is turned off (173),
Based on the OFF signal, the control unit (F) causes the rotating motor (7
The drive signal is sent again to 5) to rotate the rotation motor (75). Thereby, the clamp of the sheet paper (P) is released (174).

Thereafter, the sheet paper (P) of the toilet seat body (11) is eliminated (175), or the cleaning device is driven to clean the inside of the flush toilet (10), and the water of the flush water together with the flush water and filth is determined by the flush water. In addition, the sheet paper (P) can be rolled in and cut off at the separated portion.

Then, the rotation motor (40) is driven to feed out the sheet paper (P) by a predetermined size, for example, 20 mm (176), and the starting end of feeding out the next sheet paper (P) is fed ahead of the cutting blade (61a). Even if the start end is curled, the next delivery will be performed smoothly. Then, the rotation motor (75) is driven again to close the sheet paper feed port (85) (177). That is, the movable plate (50)
In the casing body (16), a posture capable of reliably preventing wastewater from entering the sheet paper delivery path through the sheet paper delivery port (85) can be taken.

In the above step, after the sheet paper (P) is cut and held (165) by the cooperation of the movable plate (50) and the swing plate (51), the sheet paper (P) is fed out onto the toilet seat body (11). When the sheet paper (P) is wet and the push button (103) for feeding out the sheet paper is turned on to remove it (167), furthermore, for some reason, the user moves the toilet seat body ( 11) If the user does not sit on the floor (168), regardless of the seating detection means (96), it is determined that the sheet paper (P) cannot be used or discarded because the sheet paper (P) is determined to be unused and discarded. Jump to the step.

By the way, as a result of the maintenance performed to solve the trouble, the sheet paper roll protection cover (84) is opened and closed. In this embodiment, the sheet paper roll protection means (98) is used to open and close the sheet paper roll. Open / close detecting means for detecting a series of operations of the protective cover (84) shifting from the open state to the closed state is constituted, and the sheet paper roll protective cover (84) is changed from the open state to the closed state by the open / close means (98). And a standby state return means for returning the sheet paper feeding mechanism (C) to the standby state when it is detected that the state has been shifted to.

The standby state returning means is substantially based on a program incorporated in the control unit (F), and is controlled by the cover opening / closing means (98).
4) When it detects that it has shifted from the open state to the closed state,
The sheet paper feeding mechanism (C) can be returned to the standby state based on the detection result.

That is, when the sheet paper roll protective cover (84) is closed, the subroutine starting from (C) in FIG. 14 (C) is executed, and then the process returns to (E) in the main routine.

The subroutine starting from the above (C) is shown in FIGS.
D, the sheet paper roll protective cover (84) is opened (200), and the cover open / close detecting means (98) is opened.
When the output is turned off (201), the power is turned off (20
2) The power lamp (104) is turned off (203), the user performs maintenance (204), the sheet paper roll protective cover (84) is closed (205), and the cover open / close detecting means (9
When the output of 8) turns on (206), the power turns on (20
7) The power lamp (104) is turned on (208).

Here, press the push button (103) for feeding the sheet paper to O
When N, (209) an operation start signal is input to the control unit (F),
If the condition of each part is detected and the logical product of the following four conditions does not hold, the rotary motor (40) is turned off (210) because the device has not returned to a normal state, and the paper trouble lamp (10
6) Turn on the switch and prompt for maintenance again.

That is, the output of the cover open / close detecting means (98) of the sheet paper roll protective cover (84) is ON (21).
1).

 The output of the seating detection means (96) is OFF (212).

The output of the abnormal feeding prevention sensor (97) of the toilet seat body (11)
Be ON (213).

 Sheet paper is set (214).

When the logical product of the above four conditions is satisfied, the rotation motor (75) of the sheet paper cutting mechanism (D) is rotated,
The movable plate (50) is set to the posture shown in FIG. 4, and the sheet paper feeding port (85) is opened (215).

Then, the rotation motor (40) of the sheet paper feeding mechanism (C) is activated (216), and the sheet paper (P) is fed (217).

During feeding of the sheet paper, if the position detection through hole (93) of the sheet paper (P) is not detected by the position detection sensor (94) in the time allowance (218), troubles such as a paper jam may occur. The rotation motor (4) of the sheet paper feeding mechanism (C) is regarded as having occurred.
0), the paper trouble lamp (106) is turned on (219), and the sheet paper exit (85) is closed (22).
0), return to the beginning of this subroutine.

During the feeding of the sheet paper (P), if the through hole (93) for detecting the position of the sheet paper is normally detected,
The rotation of the rotation motor (40) of the sheet paper feeding mechanism (C) is stopped (222), and the rotation motor (75) of the sheet paper cutting mechanism (D) is driven to remove the sheet paper (P). Clamp (223), then the same paper (P)
Is cut (224), and immediately, the sheet paper (P) is unclamped (225), and when the sheet paper (P) is removed (226), the sheet paper (P) is smoothened for the next feeding. Is fed out to a predetermined length (about 20 mm) (227). Thereafter, the turning motor (75) of the sheet paper cutting mechanism (D) is turned to close the sheet paper feeding port (85) (228). Then, the process returns to the standby state step of waiting for operation of the sheet paper feeding push button (103) in the main routine.

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

When the sheet paper roll protective cover (84) is opened, the power is immediately turned off and all functions of the device are stopped, so that maintenance such as replenishment of the sheet paper roll (R) and elimination of paper jams can be performed safely. In particular, even if the sheet paper roll protection cover (84) is accidentally closed while tools are placed inside the sheet paper roll protection cover (84) during maintenance work, the sheet If the button (103) is not pressed and the operation start signal is not input, it does not return to the standby state, so that there is no possibility of damaging the sheet paper feeding mechanism (C), and the maintenance work can be performed with peace of mind. After the maintenance is completed, the sheet paper roll protective cover (84) is attached, and the sheet paper feeding push button (103) is pressed, and the feeding start end position and the sheet feeding position are detected by the position detection sensor (94) also serving as paper detection. The first sheet paper (P) having an indefinite length is fed out, cut and released, so that it can be used immediately from the next time, thereby simplifying operation and handling. This has the effect of eliminating the trouble of turning on and off the feeding switch to match.
