Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an automatic sheet paper supplying toilet seat that can automatically supply sheet paper onto the toilet seat.

(b) Prior Art Betsuto Motoyama previously disclosed in Japanese Patent Application No. 63-195131 an automatic sheet paper supplying toilet seat having the following configuration.

That is, the automatic sheet paper feeding toilet seat has a sheet paper roll and a sheet paper feeding side part for feeding sheet paper from the sheet paper roll onto the top surface of the toilet seat body, in a functional part casing provided at the rear of the toilet seat body. , a sheet paper cutting mechanism section that cuts and clamps the rear end of the sheet paper fed out onto the toilet seat body from the sheet paper feeding mechanism section, and controlling the sheet paper feeding mechanism section and the sheet paper cutting mechanism section; A control unit that drives the sheet paper to feed out a set length onto the toilet seat body and cut the trailing end;
The device is characterized by a configuration in which the operating section and the operating section for making the following functions are housed and arranged in an integrated manner.

In addition, with this configuration, the sheet paper position detection sensor detects the through holes provided in the sheet paper at regular intervals, and the sheet paper is automatically and accurately fed out by a set length onto the toilet seat body. , can be positioned and then clamped after cutting.

Therefore, when using the sheet paper in a public place, the user can take out the sheet paper and use it without touching the sheet paper directly.
It is possible to improve hygiene.

(C) Problems to be Solved by the Invention However, even if the above-mentioned automatic sheet paper supply toilet seat is operating normally, if the leading edge of the sheet paper is curled due to the properties of the sheet paper, etc. If the sheet paper gets caught in the functional part casing, it will not be smoothly fed out onto the toilet seat main body through the sheet paper delivery path, and the sheet paper will be delivered only into the functional part casing.

As a result, the sheet paper position detection sensor will not detect the sheet paper, but the il, 11m section will not stop the operation of the side section of the sheet paper feeding machine unless there is a sensor output from the sensor. As a result, the sheet paper continues to be fed into the functional casing, resulting in a paper jam.
The sheet paper feeding drive motor, which is part of the sheet paper feeding mechanism, may block the motor or operate continuously, resulting in overheating and a Vt loss, resulting in a dangerous situation.

Similarly, when there is no paper, the sheet paper position detection sensor does not send sensor output to the control unit, so the sheet paper feeding drive motor either continues to operate for a long time or the motor blocks. As a result, the device becomes energized, resulting in overheating and burnout, which is also dangerous.

An object of the present invention is to provide an automatic sheet paper supply toilet seat that can solve the above problems.

(d) Means for solving the problem of ff The present invention provides a sheet paper feeding mechanism section that feeds out sheet paper from a sheet paper roll through a sheet paper feed path onto the toilet seat body, and a sheet paper feeding mechanism that feeds out sheet paper from a sheet paper roll onto a toilet seat body, in a functional part casing. A sheet paper cutting mechanism section capable of cutting the rear end and clamping the cut end and opening and closing the sheet paper outlet of the sheet paper dispensing path, and controlling the operations of the sheet paper feeding mechanism section and the sheet paper cutting mechanism section. In an automatic sheet paper supply toilet seat equipped with a control unit, if the control unit detects an abnormality in the sheet paper feeding state after operating the sheet paper feed switch, ■a paper jam has occurred in the functional unit casing. Or, it determines that the paper is out or out of paper, activates the abnormal signal generator, closes the sheet paper feed port, returns the sheet paper cutting mechanism to the original position where the sheet paper clamp is released, and then stops. The present invention relates to an automatic sheet paper supplying toilet seat characterized by comprising a control program for automatically supplying sheet paper.

In the above configuration, the abnormal sheet paper feeding state is: ■ If the sheet paper position detection sensor does not detect the sheet paper even after the set time has elapsed, or if the sensor detects the sheet paper and then within the set time If the sensor does not detect the through hole in the sheet paper, or if the sensor detects the sheet paper and then the sheet paper is unwound, the setting time is shorter than the normal setting time for feeding out one sheet of paper. (1) A state where the sheet paper position detection sensor detects a hole in the sheet paper within a set time; and (2) a no-paper state in which the sheet paper position detection sensor does not detect a hole in the sheet paper within a set time.

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

That is, in the present invention, if the sheet paper position detection sensor does not detect the sheet paper even after the set time has elapsed after operating the sheet paper feed switch, or even if the sheet paper is detected, the controller detects the sheet paper within the set time. If a hole in the sheet paper is not detected, it is determined that there is a paper jam, end of paper, or out of paper in the functional casing, and the abnormality signal generator is activated, making it easy for maintenance personnel and users to detect an abnormality. The occurrence of a condition can be detected and necessary measures can be taken quickly.

Furthermore, in addition to activating the abnormal signal generator, the sheet paper feed port is closed and the sheet paper cutting mechanism is returned to the original position where the sheet paper clamp is released, so that all functions are fully functional so that they will not be subjected to subsequent operations. Therefore, it is possible to safely and easily remove the jammed sheet paper from the functional unit casing and replace the sheet paper.

1, the sheet paper P can be effectively pressed and cut by the sheet paper cutting section 58.

Next, the structure of the sheet paper roll storage section E disposed inside the upper casing 1 will be explained.

4 to 7, reference numerals 60 and 61 are sheet paper roll holders rotatably attached to left and right bearing boxes 30 and 31, respectively. By supporting the paper tube R1, the sheet paper roll R formed by winding the sheet paper P multiple times around the paper tube R1 can be exchangeably stored in the sheet paper roll storage section E.

The above configuration will be described in more detail below. In FIG. 8, the base end of the holder mounting cylinder 62 is rotatably moved forward and backward within the cylindrical boss 38 rotatably supported in the left bearing box 30. It is arranged.

The holder attachment tube 62 houses a spring 63 therein, and the spring 63 urges the holder attachment tube 62 in the advancing direction.

On the other hand, a sheet paper roll holder 61 is rotatably attached to a cylindrical boss portion 39 rotatably supported within the right bearing box 31 by a plug 64 to prevent removal.

With this configuration, the spring 63 is compressed and the holder mounting tube 62 and the sheet paper roll holder 60 are
By retreating, both ends of the paper tube R1 of the sheet paper roll R can be supported by the sheet paper roll holders 60 and 61.

In addition, when the sheet paper P on the paper tube R1 has run out, which is a so-called paper out state, the spring 63 is compressed again to move the holder mounting tube 62 and the sheet paper roll holder 60 backward, and the sheet paper roll holder 6
From 0.61, both ends of the paper tube R1 of the sheet paper roll R can be removed as shown by imaginary lines in FIG. 8, and replaced with a new sheet paper roll R.

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 section D, and various sensors and detection means will be explained.

As shown in FIG.
It is located on the front right side of the

As shown in FIG. 9, the control section F essentially detects the microprocessor (MPLI) m and the through hole for detecting the sheet paper position provided in the sheet paper P, and generates an output. A human power interface n connected to a sheet paper position detection sensor 70, a sheet paper feeding mechanism 71 provided in the operating section G, and a control output generating means such as a z pressure detection means 72, which will be described later, and a sheet paper feeding mechanism section C and a sheet paper position detection sensor 70. It consists of an output interface 0 that connects to the paper cutting mechanism, etc., a memory 2 that stores sheet paper feeding, clamping, and cutting programs, and a timer q.

Further, in FIG. 9, r is a drive circuit interposed between the output interface 0 and the sheet paper feeding mechanism section C or the sheet paper cutting mechanism section, and S is a power supply circuit connected to the drive circuit r. .

Next, to explain from the operation part G), as shown in FIG. It is constructed by attaching a power lamp made of a light emitting diode, etc., and a paper trouble lamp, etc., which has an alarm function in the event of an abnormality such as a paper jam or paper replenishment.

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.

And, as shown in Figures 3 and 4 and Figure 1O,
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. Then, the operation of the sheet paper feeding mechanism section C is stopped, and the sheet paper P can be accurately supplied and positioned on the toilet seat main body 11.

In addition, in this example, sheet paper! The detection sensor 70 is covered by a waterproof cover 708, as shown in FIG. The target connection is a pair of lead wires passing through the cylindrical boss portion 39! ,,l,.

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
, 1.5b, 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. 12 to 14, the functional pivot 13 has an elongated hole 7 formed vertically in the inner wall 74 of the pivot portion 15a.
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 U will assume the upper position shown in Figure 3 (the position where the user is not yet seated), and the functional axis 13 and the toilet seat body U will 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.

Further, below the lever pressing piece 80, L is provided in a plan view.
A sensor activation lever 81 having a letter-shaped shape is provided.

The sensor activation lever 81 has a base end 81a supported in an upwardly biased state within a lever elevating guide casing 83 having a built-in coil spring 82, and is shielded by a 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 15a 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 urging 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 sort 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.

Further, the seating detection means 72 detects whether the user is seated on the toilet seat body 11 or
While the user is sitting on the seat, the sheet paper P is not fed out even if the sheet paper feeding push button switch 71 is pressed.

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, a toilet seat main body retaining portion 86 is provided on the toilet seat main body side of the functional axis 13 and has a flat cross-sectional shape and is formed by cutting 180 degrees opposite sides. 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 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 closes the light emitting element 85,j and the light receiving element 85b.
Since the conduction with the infrared sensor 85 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 even if the sheet paper feed-out winch chia 1 is pushed as a prank, the sheet paper Ph<In, can be prevented from being fed out from the ta section casing 15, and the sheet paper P can be prevented from becoming entangled or jammed within the functional section 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

The movable plate position detection sensors 93, 93a are provided on the bottom surface of the casing 94 near the center of the power transmission shaft 43 to which the disc cam 44 is fixed, so as not to impede the rotation of the power transmission shaft 43. sensor mounting box 95
They are housed side by side inside.

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 detection plates 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.

As shown in FIGS. 15 and 16, the detection plate 96.96a is formed in an arc shape with cutouts g and h of about 1/3, and as shown in FIG. In the overlapping state, the attachment positions of the notches g and h to the power transmission shaft 43 are shifted in the circumferential direction so that the notch angle θ is about 50 degrees.

With this configuration, the movable plate position detection sensor sensor 9
3, 93a is a movable plate that moves in conjunction with the disc cam 44 fixed to the power transmission shaft 43 in response to the blocking and opening of light from the light emitting element by the rotation of the power transmission shaft 43! -50
The rotation position or movement position of the can be detected.

That is, by rotating the detection plates 9G and 96a, the movable blur [
The position detection sensor 93.93a has a movable plate 5 at each operating position (a) to (11) shown in an explanatory diagram (FIG. 18) showing the order of operation for automatically supplying sheet paper to the toilet seat, which will be described later.
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 above-mentioned movable plate position detection sensor 93.93a, the position of the detection plate 9 (i, 9Ga (Fig. 16), and the above-mentioned operating positions (a) to (h) (Fig. 18) is shown in a table. , 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 C1C 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 rear part, so when the cut-out perforation a is cut out, the cut center part is , drips into the flush toilet bowl 10, and its lower end is submerged in standing water.

Furthermore, the sheet paper P has through holes for detecting the sheet paper position at regular intervals in the longitudinal direction on one side edge corresponding to the point between the non-perforated part d and the tip of the perforation a for cutting out. It is set up.

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, control section F, scraping section G, and Each cefsa 70.85
．． 93.93a etc., please turn on the power 100),
) If the L71 detection sensor 70 does not detect the sheet paper P (IOIN), the movable plate 50
Regardless of the position, the cam movement drive motor 41 is driven according to the cam movement subroutine SR, which will be described later (102), and returns to the original position.

Here, the origin position is a position where the sheet paper outlet 8a is completely blocked by the barrier plate 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, and the sheet paper feeding mechanism section C, sheet paper cutting mechanism section, etc. are in a state where they can wait for the operation of the sheet paper feeding switch 71 and start a series of sheet paper feeding operations. is called a standby state.

That is, at the origin position, as shown in FIG. 18(a), the sheet paper outlet 8a is closed at all costs to prevent sewage, etc. from entering the sheet paper outlet path 8 from the sheet paper outlet 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 sheet paper P is not wound is removed from the sheet paper holder 60, 61, and a new sheet paper roll R is transferred to 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.

Thereafter, when the sheet paper feed switch 71 is pressed, the operation proceeds through steps (101) and (102).

In this state, when using the flush toilet IO now, when the sheet paper feeding switch 71 is pressed (103), an operation start signal is inputted to the control unit F, and the sheet paper feeding/cutting order program read from the memory p Based on this, the control unit F generates a drive signal, and the drive signal causes the first
As shown in FIGS. 8(a) and 8(b), the cam moving drive motor 41 of the sheet paper cutting mechanism is activated.

That is, when the sheet paper feed switch 71 is pressed (10
3) First, the seating detection means 70 detects whether the person is seated on the toilet seat body l.
104), and if the toilet seat body 11 is not seated or not standing up (104N), the cam movement subroutine SRI (Fig. 20) is executed. According to the operation sequence, the cam movement drive motor 41 is driven (1
05) By the same drive, the movable plate 50 is rotated counterclockwise by the clockwise rotation of the disc cam 44, and the 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 (4), the sheet paper feeding subroutine 5R1 (
According to the operation sequence in Fig. 21), the sheet paper feeding drive motor 40 and the cam movement drive motor 41
is driven (10(i)), the sheet paper P is fed out from the sheet paper roll R, the sheet paper P is clamped and tension is applied, and the sheet paper P is torn 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 (104V).

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 (10G) to open the paper delivery port 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 body ll, 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 approximately directly below the sheet paper cutting section 58 of the swing play 1-51.

Thereafter, the cam movement drive motor 41 is restarted by a drive signal from the control unit F, and the sheet paper roll is
The vapor is clamped (held) between the vapor pressing pieces 56 and 57, and also clamped (held) between the feeding roller 33 and the holding roller 34. After that, when the drive motor 41 for moving the cam continues to drive, it is located between the two clamp parts. Tension in the feeding direction is applied to the portion of the sheet paper P where the sheet paper P is drawn (FIG. 18(e)).

Further, when the cam movement drive motor 41 continues to drive,
The sheet paper cutting section 58 of f53 dynamic brake) 51 is
The sheet paper P is pressed 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 (No. 18)
Figure (r)).

Thus, the ends of the cut sheet paper P (01) are 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 (108), and the koku count prevention time (for example, 5 seconds) elapses (109). When the person leaves the toilet seat body 11, the seating detection means 72 turns off (110), and if the off signal is output continuously for 2 seconds or more (IIIY), the control unit F controls the cam movement drive motor 41. The drive signal is sent again to the cam moving drive motor 41, and the cam moving subroutine SR shown in FIG.

Based on this, the movable plate 50 is driven until it moves to a position where the sheet paper can be removed (112). As a result, the clamp on the sheet paper P is released (No. 181
2I(g)).

After that, the user removes the sheet paper P from the toilet seat main body 11 (113) or drives the cleaning device to clean the inside of the flush toilet bowl 10, and the force of the flush water causes the flush water to flow out.
The cut h1 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 (113).

Then, if sheet paper P is excluded (113
'/), the sheet paper position IF detection sensor 70 detects this, and based on the detection output, the cam movement drive motor 41 is activated in the subroutine SR shown in FIG.

is driven until it returns to the origin position based on (114),
The sheet paper outlet 8a is completely closed by the sewage prevention barrier OP 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 leading edge of the sheet paper P is advanced from the sheet paper delivery port 8a by a small length, for example, 2011-, toward the toilet seat body 11 to prevent paper jams. (115), and the user presses the sheet paper feeding switch 71, which is a step in the normal operation routine NR.
Waiting for the switch operation (103) (18th
Figure (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), each mechanical section C, D and control section F of the automatic sheet paper supplying toilet seat A.

After turning on the power to the operation unit G and each sensor 70, 71, etc., if the sheet paper position detection sensor 70 detects the sheet paper P (IOIY), as the next action,
In order to remove the sheet paper P, the movable plate position detection sensors 93 and 93a should detect whether the movable plate 50 etc. is at the origin position (11(i)), and if it is not at the origin position (116N), the cam movement According to the operation sequence of subroutine SR+, the cam moving drive motor 41 is driven (117), and the movable plate 50 is brought to the sheet paper removal position shown in FIG. 18(g) (117).

Thereafter, the unclamped sheet paper P is removed by building maintenance personnel or other users by pulling it out from the functional part casing 15.

As a result, the sheet paper position detection sensor 70 does not detect the presence of the sheet paper P in the functional part casing 15 (118N), and the above-mentioned normal operation routine Nl
The process moves to step (114) forming part of l.

That is, the drive motor 41 for moving the cam is driven again based on the subroutine Sll shown in FIG. The sheet paper feeding opening 8a is completely closed, and the sheet paper P is advanced approximately 201 degrees toward the toilet seat body 11 (FIG. 18 (h)), and the sheet paper feeding opening 8a is completely closed by the user or the like (see FIG. 18(h)). 103) I'll have to wait.

In addition, in the above-mentioned trouble handling routine TR, the replacement work of 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 (l16Y), step (11B) is performed without driving the cam movement drive motor 41 (117).
).

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

Therefore, if the maintenance personnel presses the sheet paper feed switch 71 (119) and the seating detection means 72 is off (120Y), the cam movement drive motor 41 is activated according to the operation sequence of the cam movement subroutine SRI. The movable plate 50 is driven as shown in FIG. 18(b).
Move to the sheet paper feeding position shown in 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 SR2, 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 SR, (
If the flag Fl (clog) is not detected in FIG. 21 (123N), the routine moves to a cam movement step (112) which is part of the normal operation routine Nil.

In the same step (112), the movable plate 50 is
Subroutine St? shown in FIG. By driving the cam shifting drive motor 41 based on
1. Release the clamp caused by 1.

After that, maintenance personnel removed the sheet paper P on the toilet seat body.
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. ), step (
IO2), sheet paper P is approximately 2011+1
The paper is fed out (115), and the user waits for the user to operate the paper feeding switch 71.

Then, in the normal operation routine NR, when the user operates the sheet paper feed switch 71, the sheet paper P is fed onto the toilet seat body 11 in the above-described order.

Further, in the above step (123), if the flag I11 in the sheet paper feeding subroutine SR2 of FIG. At the same time, 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 return to the original position shown in FIG. 18(a) or FIG. 18(h) (124), all control functions for the automatic seal paper supply toilet seat are stopped.

After that, the maintenance personnel removes the upper gauging 17 (this removal operation turns off the power switch (not shown) built into the H1m section casing I5, ensuring safety), and 35 forward (2) to remove the sheet paper P stuck in the functional section chi sink 15.

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 moved without any interference, and the sheet paper P can be easily removed.

Also, in the normal operation routine Nk', step (
107), when flag Fl (jamming) or flag F2 (replenishment) is detected in the subroutine SR for sheet paper feeding shown in FIG. 21 (107Y), L
The abnormality signal generating means such as Ell is driven to notify the user (125a), and the cam movement drive morph old is driven according to the operation sequence of the cam movement subroutine Sl+, and the movable plate 50 is moved to the 18th figure(
a) or return to the original position shown in Figure 18 (h) and stop all control functions to the automatic sheet paper supply toilet seat (
125) * After that, the maintenance tool removes the upper casing 17 (note that this removal operation turns off the TLB switch (not shown) built into the functional part casing 15 as described above, ensuring safety. ), the hanging support frame 35 can be moved forward one step to remove the sheet 1-paper P stuck in the functional part casing 15, and also to replace the sheet paper roll R. It can be carried out.

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 moved one time without interference between the hanging support frame 35 and the hanging support frame 35, and the sheet paper P can be easily removed.

Further, in the normal operation routine NR, after the sheet paper P is fed onto the toilet seat body 11 (106), if the fed sheet paper P is unusable for some reason (for example, the sheet paper P is wet). ,
If the sheet paper is twisted, wrinkled, or has holes, the user can operate the sheet paper feed switch 71 again (12N) without sitting down (108N).
6Y), the process moves to the cam moving stethoscope (112), and such unusable or undesirable sheet paper P can be easily removed (113).

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

Next, the above-mentioned cam movement subroutine SR+ and seal l
