Next, the operating section G will be explained. As shown in FIG. It is constructed by installing a power lamp, a paper trouble lamp, etc., which has an alarm function in the event of an abnormality such as a paper jam or paper end.

Further, as shown in FIG. 1, in addition to the operation section G, this embodiment is equipped with a remote control device RG that can be installed at any location. It is installed at the top.

The remote control device RG includes a sheet paper feeding switch 71a and a toilet flushing switch 71.
b is installed.

Further, the remote control device RG is connected to the control section F by a lead wire 71c.

Note that the remote control device RG wirelessly controls the control unit F.
It can also be configured to send control signals to.

And the above operation part G and remote controller) IAJ
In the device Q, the sheet paper feed switches 71, 7
1a and the toilet bowl cleaning switch 71b are all composed of non-contact sensors such as photoelectric sensors.

Therefore, a control signal can be generated and transmitted to the control unit F by simply holding the hand in front of the user.

Next, a position detection sensor 7 that detects the sheet paper position detection transparent hole provided in the sheet paper P and generates an output.
0, such a sensor 70 is, for example,
It can be formed by combining a phototransistor and a photodiode.

Then, as shown in FIGS. 3, 4, and 10,
In this embodiment, the sheet paper position detection sensor 70 is
It is disposed at the front right side of the functional part casing 15, and can detect position detection through holes provided at regular intervals in the sheet paper P.

That is, when the sheet paper P is fed out a predetermined length from the sheet paper roll R onto the toilet seat main body 11 by the drive of the sheet paper feeding mechanism section C, the sheet paper position detection sensor 70 detects the position detection through-hole. After receiving the detection signal, the control section F stops the operation of the sheet paper feeding mechanism section C and accurately feeds the sheet paper P.
can be supplied and positioned on the toilet seat body.

In this embodiment, the sheet paper position detection sensor 70 is covered by a waterproof cover 708, as shown in FIG. Electrical connection with the control section F disposed in is made by two pairs of lead wires 1+ and 1g passing through the cylindrical post section 39.

Next, the configuration of the seating detection means 72 will be specifically explained with reference to FIGS. 11 to 14.

As shown in FIG. 11, both rear ends of the toilet seat body 11 are
By the functional axis 13 and the simple axis 13a, respectively,
Pivot parts 15a provided on both sides of the front part of the functional part casing 15
, 15b, it is detachably attached and rotatable in the vertical direction. The seating detection means 72 is disposed within the pivot portion 15a and is operatively connected to the functional pivot 13.

As shown in FIGS. 11 to 14, the functional pivot 13 has an elongated hole 7 formed in the inner wall 74 of the pivot portion 13a to be long in the vertical direction.
5 and inserted into the pivot portion 15a.

The insertion portion of the functional pivot 13 is rotatably supported by a movable bearing 77 that is disposed within the elevating guide casing 76 so as to be movable up and down.

Note that the movable bearing 77 is always urged upward by the coil spring 78, but its upper limit position is regulated by the regulation plate 79, so normally the first
The toilet seat body 11 assumes the upper position shown in Figure 2 (the position where the user is not yet seated), and the functional axis 13 and the toilet seat body 11 also take the upper position shown in the same figure.

The functional pivot 13 also has a lever pressing piece 8 at its insertion tip.
As is clear from FIG. 13, the lever pressing piece 80 is shown as a segment of approximately a quarter arc whose center is the same as the axis of the functional pivot 13.
The radius of the outer periphery of the segment is considerably larger than the radius of the functional axis 13.

Note that the shape of the lever pressing piece 80 is not limited to a substantially quarter arc segment, and is not limited to this as long as the radius of the outer circumferential edge is considerably larger than the radius of the functional pivot 13.

Furthermore, below the lever pressing piece 80, there is a
A sensor activation lever 81 having a letter-shaped shape is provided.

The sensor activation lever 81 has its base end 8La supported in a lever ascending guide casing 83 having a built-in coil spring 82 therein so as to be able to rise and fall in an upwardly biased state, and is shielded by its distal end 81b. A plate 84 is provided protrudingly.

Therefore, the upper surface of the sensor activation lever 81 is always in contact with the lever pressing piece 80 by the coil spring 82.

The shielding plate 84 also covers a light emitting element 85 of an infrared sensor 85 disposed within the pivot portion 13a of the functional unit casing 15.
a and the light receiving element 85b.

Next, the operation of the seating detection means 72 having the above configuration will be explained.

When a user sits on the toilet seat body 11, the user's weight causes the functional axis 1 to move against the biasing force of the coil spring 78.
3. The movable bearing 77 and the lever pressing piece 80 are lowered together, and in conjunction with the lowering, the sensor activation lever 81 is also lowered,
Since the shielding plate 84 releases the conduction shielding between the light projecting element 85a and the light receiving element 85b, the infrared sensor 85 can generate an ON output.

On the other hand, when the user leaves the toilet seat body 11, the weight is released, and the urging force of the coil spring 78 causes the function pivot 13. Movable bearing 77 and lever pressing piece 80
are raised integrally, and in conjunction with the rise, the sensor activation lever 81 is also raised by the biasing force of the coil spring 82.
Since the shielding plate 84 interrupts conduction between the light projecting element (photodiode) 85a and the light receiving element (phototransistor) 85b, the infrared sensor 85 can generate an off output.

The detection output of the seat detection means 72 having the above configuration can cause each mechanism in the automatic sheet paper supply toilet seat to perform arbitrary operations, but in this embodiment, the following operations are performed. There is.

That is, the seating detection means 72 generates a detection signal when the user leaves the toilet seat body 11 after a certain period of time has passed after the user sits on the toilet seat body 11, and activates the control unit F.
The clamping of the sheet paper P by the sheet paper cutting mechanism section C can be released.

Thereafter, when the user removes the used sheet paper P, the movable plate 50 is rotated in response to a signal from the sheet paper position detection sensor 70 so as to block the entry of dirty water into the sheet paper delivery path 8.

Furthermore, by detecting the seating of the user by the seating detection means 72, the sheet paper P is not fed out even if the user operates the sheet paper feeding switch 71, 71a while the user is sitting on the toilet seat main body 11. ing.

Furthermore, in this embodiment, as shown in FIGS. 11 and 12, the seating detection means 72 is configured to also function as a toilet seat main body upright detection means.

That is, as shown in both figures, on the toilet seat body side of the functional axis 13, there is provided a toilet seat body engaging portion 86 with a flat cross-sectional shape formed by cutting 180 degrees opposite sides, and the toilet seat body engaging portion 86 is formed by cutting the sides opposite to each other by 180 degrees. The portion 86 is removably provided on a corresponding side of the rear portion of the toilet seat main body 11 and is fitted into a pivot engagement hole 87 having the same shape as the toilet seat main body retaining portion 86 .

Therefore, since relative rotation is not possible between the toilet seat main body 11 and the functional pivot 13, when the toilet seat main body 11 is rotated and raised, the functional pivot 13 also rotates integrally, and by the same rotation, the insertion end of the functional pivot 13 is rotated. The provided lever pressing piece 80 also rotates.

By the way, since the radius of the lever pressing piece 80 is considerably larger than the radius of the functional axis 13, the lever pressing piece 80
, the functional pivot 13. is rotated against the biasing force of the coil spring 78. The movable bearing 77 and the lever pressing piece 80 lower together, and in conjunction with the lowering, the sensor activation lever 8
1 also descends, and the shielding plate 84 covers the light emitting element 85a and the light receiving element 8.
Since the conduction shielding with 5b is released, the infrared sensor 85 can generate an ON output.

On the other hand, when the toilet seat main body 11 is returned from the upright position to the horizontal sitting position, the pressing force of the lever pressing piece 80 on the sensor activation lever 81 is released, so that the urging force of the coil spring 78 is applied to the functional pivot 13. The movable bearing 77 and the lever pressing piece 80 rise together, and in conjunction with the rise, the sensor activation lever 81 also rises due to the urging force of the coil spring 82, and the shielding plate 84 connects the light emitting element 85a and the light receiving element 85b. Since the conduction is interrupted, the infrared sensor 85 can generate an off output.

Based on the sensor output, the control section F controls the sheet paper feeding mechanism section C to stop operating when the toilet seat main body 11 is in the upright state.
Or, as a prank, the sheet paper feed switch 71 (7
Even if 1a) is operated, the sheet paper P can be prevented from being fed out from the functional part casing 15,
Entanglement and clogging of the sheet paper P within the functional part casing 15 can be reliably prevented.

Next, the configuration and operation of the movable plate position detection sensors 93, 93a that detect the current rotated position of the movable plate 50 will be explained in FIGS. 6, 7, and 14 to 16.
This will be explained with reference to the figures.

The movable plate position detection sensor 93.93a is mounted on the bottom surface of the lower casing 16 near the center of the power transmission shaft 43 to which the disc cam 44 is fixed.
They are housed in a side-by-side state in a sensor mounting box 95 that is provided so as not to impede the rotation of the sensors 3 and 3.

The movable plate position detection sensors 93, 93a are
As shown in FIGS. 14 and 15, the planar shape is U-shaped, and a light-emitting element (photodiode) and a light-receiving element (phototransistor) are respectively provided on the opposing walls of this U-shaped part. are doing.

Furthermore, a pair of shielding disks 96 and 96a fixed to the power transmission shaft 43 at a constant interval in the axial direction are loosely fitted into the U-shaped portions of the movable plate position detection sensors 93 and 93a, respectively.

The shielding discs 96.96a are shown in FIGS.
As shown in the figure, it is formed in an arc shape with about 173 notches g and h, and as shown in FIG. The mounting position on the power transmission shaft 43 is shifted in the circumferential direction so that θ.

With this configuration, the movable plate position detection sensor 93
, 93a rotates a movable plate 50 that moves in conjunction with a disk cam 44 fixed to the power transmission shaft 43 in response to the rotation of the power transmission shaft 43 to block or unblock light from the light emitting element. The position or movement position can be detected.

That is, due to the rotation of the shielding disks 96, 96a, the movable plate position detection sensors 93, 93a are activated as shown in the explanatory diagram (18th
The movable plate 5 is placed at each operating position (a) to (h) shown in the figure.
It is possible to reliably detect that zero has arrived, and based on the detection output, the sheet paper feeding mechanism section C etc. can be accurately driven to perform a desired operation.

The relationship between the positions of the movable plate position detection sensors 93, 93a, the shielding discs 96, 96a (Fig. 16), and the operating positions (a) to (h) (Fig. 18) is shown in a table. It will be as follows.

Next, the structure of the sheet paper P will be explained with reference to FIG. 17. The sheet paper P has linear cutting perforations C in the width direction at regular intervals in the longitudinal direction or the feeding direction. , the sheet paper P is pressed and cut along the same perforation C.

In addition, the sheet paper P has a cutout perforation a in the center between the cutout perforation C3C and the cutout perforation a that matches the inner shape of the toilet seat body 11. By cutting out the paper P, an opening communicating with the inside of the flush toilet 10 can be provided.

However, the cut-out perforation a is not completely annular, and a non-perforated part d is formed between both ends of the front part, so when the cut-out perforation a is cut out, the cut out central part drips into the flush toilet bowl 10, and its lower end is submerged in standing water.

Furthermore, the sheet paper P is provided with through holes for detecting the sheet paper position at regular intervals in the longitudinal direction, for example, at the edge corresponding to the edge between the perforation C and the tip of the perforation a for cutting out. ing.

Next, regarding the operation of using the automatic sheet paper supplying toilet seat having the above configuration, with reference to the operation sequence explanatory diagram shown in FIG. 18 and the flowcharts shown in FIGS. 19 to 21,
Explain in detail.

First, to explain the normal operation sequence in which no trouble occurs (normal operation routine NR shown by the thick line in Fig. 19), each mechanism section C, D of the automatic sheet paper supply toilet seat A, the control section F, the operation section G, the remote If the sheet paper position detection sensor 70 does not detect the sheet paper P, turn on the power to the control device RG and each sensor 70, 85°93.93a, etc. (100).
N) Regardless of the position of the movable plate 50, the cam movement drive motor 41 is driven according to the cam movement subroutine SRI to be described later (102) to return to the original position.

Here, the origin position is a position where the sheet paper outlet 8a is completely blocked by the barrier brake 1-BP provided at the tip of the movable plate 50, as shown in FIG. 18(a). Note that the movable plate 50 is at the origin position,
The sheet paper feeding mechanism section C, the sheet paper cutting mechanism section, etc. are connected to the sheet paper feeding switch 71 (71a
The state in which a series of sheet paper feeding operations can be started after waiting for the operation of ) is called a standby state.

That is, at the origin position, as shown in FIG. 18(a), the sheet paper delivery port 8a is closed at one end to prevent sewage, etc. from entering the sheet paper delivery path 8 from the sheet paper delivery port 8a. is being prevented.

Further, if the sheet paper position detection sensor 70 does not detect the sheet paper P (IOIN) and the movable plate 50 is already at the origin position, the origin position return operation (102) is determined to be unnecessary, and the same operation is performed. will not be carried out.

Furthermore, when replacing the sheet paper roll R, the above steps (101) and (102) are also passed through.

That is, the upper casing 17 is removed from the lower casing 16, the paper tube R1 on which no sheet paper P is wound is removed from the sheet paper holders 60 and 61, and a new sheet paper roll R is inserted into the sheet paper holder 6.
Attach it to 0.61.

Then, from the sheet paper roll R to the sheet paper P
The length is sufficient to hold the paper between the feed roller 33 and the press roller 34, and the sheet paper position detection sensor 70 does not detect the sheet paper P. The machine frame 35 is swung forward, and the unwinding end of the sheet paper P is moved to the feed roller 3.
3 and a pressing roller 34.

After that, pressing the sheet paper feed switch 71,
Or, by placing your hand in front of 71a, you can press the sheet paper feed switch 71.71 without touching it directly with your hand.
By operating a, the operation proceeds through steps (101) and (102).

In this state, when using the flush toilet 10 now, when the sheet paper feeding switch 71a on the remote control device RG or the sheet paper feeding switch 71 on the operation part G is pressed (103), an operation start signal is sent to the control part F. Sheet paper feeding/reading from memory p
Based on the cutting order program, the control unit F generates a drive signal, and the drive signal causes the cuts in FIGS.
As shown in FIG. 3, the cam moving drive motor 41 of the sheet paper cutting mechanism is activated.

That is, when the sheet paper feeding switch 71 (71a) is operated (103), the seating detection means 70 first determines whether a person is sitting on the toilet seat body 11 or whether the toilet seat body 11 is standing up or not. (10
4) If not seated or standing (104N)
), cam movement subroutine SR, (FIG. 20), the cam movement drive motor 41
is driven (105), and due to this drive, the disc cam 4
4 rotates in the clockwise direction, the movable plate 50 rotates counterclockwise, and a sheet paper delivery path 8 communicating with the sheet paper delivery port 8a is formed on the movable plate 50 (FIG. 18). (b)).

Thereafter, as shown in FIGS. 18(c), (d), (e), and (f), the sheet paper feeding subroutine 5R2 (
According to the operation sequence in Fig. 21), the sheet paper feeding drive motor 40 and the cam movement drive motor 41
is driven (106), and the sheet paper P is fed out from the sheet paper roll R, and the sheet paper P is clamped and given a tensile run, so that the sheet paper P is broken at the perforation C.

In addition, in the above step, if the toilet seat main body 11 is in the rotating upright state or the user is seated due to some reason including mischief, the seating detection means 72 should detect this fact (104Y) and output the same detection output. As long as there are
Therefore, the sheet paper P is not fed out (104Y).

Then, when the toilet seat main body 11 is returned to its original horizontal seating position, the seating detection means 72 is turned off (104N), and step (
105) The movable plate 50 moves via (106) to open the sheet paper outlet 8a, and
It becomes possible to automatically feed out the sheet paper P onto the toilet seat body 11 (106).

Then, the sheet paper P is fed out onto the toilet seat main body 11, and then the sheet paper position detection sensor 70
When the through-hole provided in the sheet paper P is detected within a predetermined time, the sheet paper feeding drive motor 4 feeds out the sheet paper P by a set length onto the toilet seat body 11.
0 stops (FIG. 18(d)).

Note that at this point, the perforation C located at the rear end of the sheet paper P is located substantially directly below the sheet paper cutting portion 58 of the swing plate 51.

Thereafter, the cam movement drive motor 41 is restarted by a drive signal from the control unit F, and the sheet paper P is clamped (held) between the sheet paper pressing pieces 56 and 57, and also between the feeding roller 33 and the holding roller 34. When the cam movement drive motor 41 continues to drive after being clamped (held), tension in the feeding direction is applied to the portion of the sheet paper P located between the two clamped portions (Fig. 18). (e)).

Further, when the cam movement drive motor 41 continues to drive,
The sheet paper cutting section 58 of the swing plate 51 presses the sheet paper P along the perforation C, and the sheet paper P is reliably broken, that is, cut, by the pressing force and the tension in the feeding direction. (Figure 18 (
f)).

Thus, the rear end of the cut sheet paper P is securely clamped by the sheet paper pressing pieces 56 and 57 (FIG. 18(f)).

Thereafter, when the user sits on the toilet seat main body 11, the seating detection means 72 detects that the user is seated (108Y), and the mischief prevention time (for example, 5 seconds) elapses (109Y). When the person leaves the main body 11, the seating detection means 72 turns off (IIOY), and if the same off signal is output continuously for 2 seconds or more, for example (IIIY)
, the control unit F sends a drive signal to the cam movement drive motor 41 again, and the cam movement drive motor 41 is activated so that the movable plate 50 can remove the sheet paper based on the cam movement subroutine SR+ shown in FIG. It is driven until it moves to the position (112). As a result, the clamp on the sheet paper P is released (FIG. 18(g)).

After that, the user removes the sheet paper P from the toilet seat main body 11 (113N) or drives the cleaning device to clean the inside of the flush toilet bowl 10, and the flushing water is flushed by the force of the flushing water.
The cut-off portion of the sheet paper P can be rolled up and flowed out together with the dirt, and the sheet paper P can be removed (113N).

Then, if sheet paper P is excluded (113
N), the sheet paper position detection sensor 70 detects this, and the detection output causes the cam movement drive motor 4 to
1 in the subroutine Sl? shown in FIG. .

114).
The sheet paper outlet 8a is completely closed by the sewage prevention barrier BP provided at the tip of the movable plate 50.
(Figure 18(h)).

That is, the movable plate 50 can take a position within the functional unit casing 15 that can reliably prevent dirty water from entering the sheet paper delivery path 8 through the sheet paper delivery port 8a.

Thereafter, the sheet paper feeding drive motor 40 is restarted, and the tip of the sheet paper P is moved from the sheet paper delivery port 8a by a short distance, for example, 20 m, to the toilet seat main body 1.
1, paper is ejected to prevent paper jams (115), and the sheet paper [%] eject switch 71 is operated by the user (103), which is a step in the normal operation routine NR. (Figure 18 (
h)(a)).

Next, a trouble handling routine TR will be described, which deals with a case where a trouble such as a momentary power outage occurs during the execution of the above-described normal operation routine NR.

That is, in step (100), after turning on the power to each mechanism section C, D, control section F, operation section G, and each sensor 70, 71, etc. of the automatic sheet paper supply toilet seat A, the sheet paper position detection sensor 70 is turned on. If the sheet paper P is detected (IOIY), the next step is to check whether the movable plate 50 and the like are at the origin position so that the sheet paper P can be removed by the movable plate position detection sensor 93,
93a (116), and if it is not at the home position (116N), the cam movement drive motor 41 is driven (117) according to the operation sequence of the cam movement subroutine SR, and the movable plate 50 is moved to the position shown in FIG. g
) to the position where the sheet paper can be removed (11).
7).

Thereafter, building maintenance personnel, users, etc. remove the unclamped sheet paper P by pulling it out of the functional part casing 15.

As a result, when the sheet paper position detection sensor 70 no longer detects the presence of the sheet paper P in the functional unit casing 15 (118N), the above-mentioned normal operation routine NR
The process moves to step (114), which forms part of the process.

That is, the cam movement drive motor 41 is driven again based on the subroutine SR1 shown in FIG. , completely close the sheet paper outlet 8a, advance the sheet paper P toward the toilet seat main body 11 for about 20 m++s (FIG. 18(h)), and press the sheet paper feed switch 71 (71a) by the user or the like. Operation (103)
will have to wait.

In addition, in the above-mentioned trouble handling routine TR, when replacing the sheet paper roll R, the upper casing 1
7, after turning off the power, attach the sheet paper roll R to the functional part casing 15 with the tip of the sheet paper P sufficiently rewound from the sheet paper outlet 8a to the toilet seat body 11, After that, by attaching the upper casing 17, it is possible to reenergize.

In this case, the sheet paper position detection sensor 70 detects the presence of the sheet paper P in the functional unit casing 15.
is detected (l0IY) and the movable plate 50 is at the origin position (116Y), the cam movement drive motor 41 is not driven (117) (step (118)).
).

Then, in step (118) as well, the sheet paper position detection sensor 70 detects the sheet paper P (118Y).

Then, maintenance personnel turned on the sheet paper feed switch 71a.
or 71 (119Y), and seating detection means 7
2 is off (120Y), the cam movement drive motor 41 is driven according to the operation sequence of the cam movement subroutine SRI, and the movable plate 50 is moved to the sheet paper feeding position shown in FIG. 18(b). 121), the sheet paper P can be fed out.

After the above cam movement operation is completed, the sheet paper feeding drive motor 40 is driven according to the operation sequence of the sheet paper feeding subroutine SRz, and the sheet paper P
is fed out toward the toilet seat body 11, and then the sheet paper P is clamped and then torn at the perforation C.
The clamped state will be maintained as it is (122
).

Then, in the same sheet paper feeding operation (122), the sheet paper feeding subroutine 5RZ (
If the flag Fl (blockage blockage) in FIG. 21) is not detected (123N), the routine moves to a cam movement step (112) which is part of the normal operation routine NR.

In the same step (112), the movable plate 50 is
By driving the cam movement drive motor 41 based on the subroutine SR shown in FIG. The clamp with the plate 51 is released.

After that, maintenance personnel remove the sheet paper P on the toilet seat body 11.
When the sheet paper P is pulled out and removed, the sheet paper position detection sensor 70 detects that the sheet paper P has been removed, and based on the detection output, the movable plate 50 returns to the original position again as described above (114). , in step (103), the sheet paper P is heated to about 20-
The sheet paper feed switch 71a or the sheet paper feed switch 71 is fed out (115) by the user.
Waiting for switch operation.

Then, in the normal operation routine NR, the user selects the sheet paper feeding switch 71a or the sheet paper feeding switch? By operating 1 and 71a, the sheet paper P is fed out onto the toilet seat body 11 in the above-described order.

Further, in step (123), if flag F1 in the sheet paper feeding subroutine SRt of FIG. At the same time, the cam movement drive motor 41 is driven according to the operation sequence of the cam movement subroutine SRI to move the movable plate 50.
In order to return to the original position shown in FIG. 18(a) or FIG. 18(h) (124), all control functions of the automatic sheet paper supplying toilet seat A are stopped.

After that, the maintenance personnel removes the upper casing 17 (this removal operation turns off the power switch (not shown) built into the functional part casing 15, ensuring safety), and 3
The sheet paper P stuck in the functional part casing 15 can be removed by swinging the paper sheet 5 forward.

In this removal work, since the movable plate 50 is at the origin position, the movable plate 50 and the suspension support frame 35
The hanging support frame 35 can be easily swung without any interference, and the sheet paper P can be easily removed.

Also, in the normal operation routine NR, step (1
07), when the flag Fl (paper jam) or flag F2 (paper replenishment) in the sheet paper feeding subroutine sRz of FIG. 21 is detected (107Y), the LE
The abnormality signal generating means such as D is driven to notify the user of this (124a), and the cam movement drive motor 41 is driven according to the operation sequence of the cam movement subroutine SR, and the movable plate 50 is moved to the 18th Diagram (a)
Or return to the original position shown in Fig. 18 (h) and stop all control functions of the automatic sheet paper supply toilet seat A (12
5).

After that, the maintenance personnel removes the upper casing 17 (note that this removal operation turns off the power switch (not shown) built into the functional part casing 15 as described above, thereby ensuring safety. ), the hanging support frame 35 can be swung forward to remove the sheet paper P stuck in the functional part casing 15, and also to replace the sheet paper roll R.

Even in such sheet paper removal work, since the movable plate 50 is at the origin position, the movable plate 50
The hanging support frame 35 can be easily swung without interference between the hanging support frame 35 and the hanging support frame 35, and the sheet paper P can be easily removed.

Furthermore, in the normal operation routine NR, after the sheet paper P is fed out onto the toilet seat body lI (106), if the fed out sheet paper P is in an unusable state for some reason (for example, the sheet paper P is wet). ,
If the sheet paper is twisted and wrinkled or has holes, the user can operate the sheet paper feeding switch 71 again (12N) without sitting down (108N).
6Y), the process moves to a cam movement step (112), and such unusable or unused sheet paper P can be easily removed (113).

Further, as described above, when the sheet paper P is removed (113N), the sheet paper position detection sensor 70 detects this, and the detection output causes the cam movement drive motor 41 to move as shown in FIG. Subroutine S
R, and drive until it returns to the origin position 114)
, sewage prevention barrier B provided at the tip of the movable plate 50
P completely closes the sheet paper outlet 8a (FIG. 18(h)'').

That is, the movable plate 50 can take a position within the functional unit casing 15 that can reliably prevent dirty water from entering the sheet paper delivery path 8 through the sheet paper delivery port 8a.

In addition, after feeding the sheet paper P onto the toilet seat body ll (1
06) If the user, for some reason (e.g.
If a certain period of time (for example, 1 minute) has elapsed without sitting on the toilet seat main body 11 (108N) and without operating the sheet paper feed switch 71 (126N), (127Y) , immediately proceed to the cam movement step (112), and the next user:
The sheet paper P fed out onto the toilet seat body 11 can be removed (113).

In this case as well, the sheet paper position detection sensor 70 detects that the sheet paper P has been removed, and based on the detection output, the cam movement drive motor 41 is moved to the origin position based on the subroutine SR shown in FIG. 114), the sewage prevention barrier BP provided at the tip of the movable plate 50 closes the sheet paper outlet 8a.
is completely closed (Fig. 18(h)).

That is, the movable plate 50 can take a position within the functional unit casing 15 that can reliably prevent dirty water from entering the sheet paper delivery path 8 through the sheet paper delivery port 8a.

Next, the contents of the cam movement subroutine SR+ and the sheet paper feeding subroutine SR1 described above will be explained with reference to FIGS. 20 and 21.

First, the cam movement subroutine SR+ will be explained with reference to FIG. 20. If the disc cam 44 has already reached the specified cam position (201Y), the normal operation routine NR shown in FIG. Return to routine TR.

On the other hand, if the disc cam 44 has not reached the designated cam position (201N), drive the cam movement drive motor 41 until it reaches the designated cam position (203), and if it has reached the designated cam position (204Y), The cam movement drive motor 41 is stopped (205), and then the routine returns to the normal operation routine NR or troubleshooting routine TR shown in FIG.

In addition, even if the movable plate position detection sensors 93, 93a malfunction or the cam movement drive motor 41 is driven (203), the disc cam 44 may not move to the designated cam even if the set time (for example, 5 seconds) has elapsed. If the position is not reached (20
4N), (206),) It is determined that a trouble has occurred, and the cam movement drive motor 41 is stopped regardless of the position of the disc cam 44 and the movable plate 50, and all control of the automatic sheet paper supply toilet seat A is performed. The function is stopped (207).

This can prevent the cam movement drive motor 41 from burning out due to overheating, and
It is possible to prevent wear caused by repeated sliding between the contact surfaces of the movable plate 50 and the swing plate 51.

Next, the sheet paper feeding subroutine SIh will be explained with reference to FIG. 21. By driving the sheet paper feeding drive motor 40 (301), the sheet paper When the position detection sensor 70 detects a through hole (30
3Y), its detection is performed by the sheet paper feeding drive motor 4.
If the set time (for example, 2 seconds) or more has elapsed after the start of the 0 drive, it is determined that the paper is not finished (304Y), the sheet paper feeding drive motor 40 stops, and the sheet paper P is fed by the feeding roller 33 and the pressing roller 34. Clamp (305).

Next, drive the cam movement drive motor 41 (306),
When the movable plate 50 comes to the position where the sheet paper P is clamped by cooperation with the swing plate 51, (3
07Y), the drive of the drive motor 41 for cam movement is stopped and the clamping is continued 308), and then the normal operation routine NR or trouble handling routine ↑ shown in FIG.
Return to R.

In addition, in the sheet paper feeding subroutine SRz, the sheet paper feeding drive motor 40 is driven (
301) If the hole in the sheet paper P is not detected (302Y), it is determined that a paper jam has occurred (309), the flag F1 is turned on, and the sheet paper is removed. The drive of the feeding motor 40 is stopped (305).

On the other hand, even if the sheet paper position detection sensor 70 detects a through hole (303Y), if the same detection occurs within 2 seconds from the start of driving the sheet paper feeding drive motor 40 (304N), the sheet paper It is determined that the sheet paper P in the paper roll R is used up and paper replenishment is necessary (310), and the flag F2 is turned on to stop driving the sheet paper feeding drive motor 40 (310).
05).

When the above-mentioned paper jam or paper replenishment state occurs, the process returns to the normal operation routine NR through operation steps (306), (307), and (308), and flag F1 or flag F2 is detected in operation step (107). (107Y)
Therefore, an abnormality signal generating means such as an LED is activated to notify the user of the occurrence of an abnormal condition (125a), and
The cam movement drive motor 41 is driven based on the subroutine SR shown in FIG. 20 to return to the home position.
5) The automatic sheet paper supply toilet seat A stops all control functions.

In addition, the movable plate position detection sensors 93 and 93a fail, and after the cam movement drive motor 41 is driven (306),
If the disc cam 44 does not reach the specified cam position even after the set time (for example, 5 seconds) has elapsed, (307Y), (31
1Y) When it is determined that a trouble has occurred, the drive of the cam movement drive motor 41 is stopped regardless of the position of the disc cam 44 and the movable plate 50, and all control functions of the automatic sheet paper supply toilet seat A are stopped. (312).

As a result, the sheet paper feeding subroutine Sl
? Similarly to the cam movement subroutine SR, in Z, the cam movement drive motor 41 can be prevented from being burnt out due to overheating, and the contact surfaces of the movable plate 50 and the swing plate 51 can be prevented from being burnt out. Wear caused by repeated sliding can be prevented.

Furthermore, in this embodiment, the output is turned off when the person leaves the seat after using the toilet, the output is activated when the sheet paper feeding switch 71 is pressed again, or the predetermined period of time has elapsed due to an output when the sheet paper feeding switch 71 is pressed again, or when the user does not sit on the toilet seat main body 11. However, if the seating detection means 72 does not detect the seating, the sheet paper cutting mechanism is moved to the sheet paper holding release position where the sheet paper P is unclamped and the sheet paper outlet 8a is opened. It can be moved, and in the sheet paper holding release position, the sheet paper P can be easily removed from the sheet paper outlet 8a and disposed of in the toilet bowl.

After that, when the sheet paper P is removed and the sheet feeding position detection sensor 70 does not detect the sheet paper P, the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section are set to the fully open state, and the sheet paper feeding port 8a is fully opened. , release the clamp on sheet paper P,
By the next operation of the sheet paper feed switch 71,
It is possible to return the sheet paper P to the origin position where it can be fed out.

Then, at the same origin position, the sheet paper outlet 8
Since a is in a fully closed state, it is possible to reliably prevent sewage from entering the functional unit casing 15.

As explained above, in this embodiment, the operation switches 71, 71a and 71b of the operation section are configured with non-contact sensors, so that the sheet paper P can be moved to the toilet seat body 11 by simply waving your hand in front of the sensor. It can be rolled up.

In this way, regardless of the previous user, the operation switch can be operated without touching it with the hands, making the operation extremely hygienic.

Therefore, the usability of the automatic sheet paper supply toilet seat can be significantly improved, particularly in office buildings, public restrooms, or hospital restrooms.
