It is configured by installing a paper trouble lamp or the like having an alarm function when an abnormality such as paper jam or paper replenishment occurs.

Next, the configuration of the seating detecting means 72 will be specifically described with reference to FIGS. 9 to 12.

As shown in FIG. 9, both ends of the rear part of the toilet seat body 11 are detachably attached to the pivotal support parts 15a and 15b provided on both front sides of the functional part casing 15 by the functional pivot shaft 13 and the simple pivot shaft 13a, respectively. It is mounted so that it can rotate upright in the vertical direction.
The seating detection means 72 is disposed in the pivotal support portion 15a and is interlocked with the functional pivot shaft 13.

As shown in FIGS. 10 to 12, the functional pivot 13 has a pivot 15
It is inserted into the pivotal support portion 15a by penetrating a long hole 75 formed in the inner side wall 74 of a in the vertical direction.

The insertion portion of the functional pivot 13 is rotatably supported by a movable bearing 77 that is vertically movable in an up-and-down guide casing 76.

The movable bearing 77 is constantly urged upward by a coil spring 78, but the upper limit position is the restriction plate.
Since it is regulated by 79, normally, it takes the basic position shown in FIG. 10, and the functional pivot 13 and the toilet seat body 11 also take the basic position shown in the same figure.

Further, the functional pivot 13 is provided with a lever pressing piece 80 protruding from the insertion tip thereof, and the lever pressing piece 80 has a center substantially the same as the axis of the functional pivot 13 as is clear from FIG. It is shown as a quarter-arc segment, the radius of the outer periphery of which is considerably larger than the radius of the functional pivot 13.

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

Further, below the lever pressing piece 80, a sensor starting lever 81 having an L-shape in plan view is arranged.

Further, the sensor starting lever 81 is supported in a lever elevating guide casing 83 having a coil spring 82 built-in in a base end portion 81a so as to be able to ascend and descend upward in a biased state, and a shield plate at a tip portion 81b thereof. 84 are projected.

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

Further, the shielding plate 84 is provided on the pivot portion 15 of the functional portion casing 15.
Light emitting element 85a and light receiving element of infrared sensor 85 arranged in a
It is installed between 85b.

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

When the user sits on the toilet seat body 11, the weight of the seat functions against the biasing force of the coil spring 78.
The movable bearing 77 and the lever pressing piece 80 are integrally lowered, and the sensor starting lever 81 is also lowered in conjunction with the lowering, and the shielding plate 84 releases the conduction shield between the light projecting element 85a and the light receiving element 85b. The sensor 85 can generate an ON output.

On the other hand, when the user separates from the toilet seat body 11, its weight is released, so the functional pivot 13, the movable bearing 77, and the lever pressing piece 80 are integrally lifted by the urging force of the coil spring 78, and the same rises. In conjunction with this, the sensor starting lever 81 also rises due to the biasing force of the coil spring 82, and the shielding plate 84 blocks the conduction between the light projecting element 85a and the light receiving element 85b, so that the infrared sensor 85 can generate an off output. .

Then, the detection output of the seating detection means 72 having the above-mentioned configuration is such that each mechanism in the seat paper automatic feed toilet seat can perform any operation, but in the present embodiment, the following operation is 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 time elapses after the user sits on the toilet seat body 11, activates the controller F, and The clamp of the sheet paper P by the cutting mechanism C can be released.

After that, when the user removes the added sheet paper P, the signal from the sheet paper position detection sensor 70 causes
The movable plate 50 can be rotated so as to block the entry of dirty water into the sheet paper delivery path 8.

Further, the attachment / detachment detecting means 72 is configured such that, while the user is seated on the toilet seat body 11, the sheet paper P is not delivered even if the user pushes the sheet paper delivery push button switch 71.

Further, in this embodiment, as shown in FIG. 10 and FIG. 11, the seating detection means 72 is configured so as to also function as the toilet seat body upright detection means.

That is, as shown in both figures, the toilet seat main body side of the functional pivot 13 is provided with a toilet seat main body engaging portion 86 having a flat cross-sectional shape formed by cutting the side opposite to 180 degrees. Part 86
Are detachably mounted on the corresponding sides of the rear portion of the toilet seat body 11 and are fitted into a pivotal engagement hole 87 having the same shape as the toilet seat body engagement portion 86.

Therefore, since the relative rotation cannot be performed between the toilet seat body 11 and the functional pivot shaft 13, when the toilet seat body 11 is rotated and erected, the functional pivot shaft is rotated.
13 also rotates integrally, and by this rotation, the lever pressing piece 80 provided at the insertion end of the functional pivot 13 also rotates.

By the way, since the radius of the lever pressing piece 80 is considerably larger than the radius of the functional pivot 13, the rotation of the lever pressing piece 80 lowers the sensor starting lever 81 against the biasing force of the coil spring 82, Since the shield plate 84 releases the conduction block 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 toilet seat body 11 is returned from the upright position to the horizontal seating position, the pressing force applied to the sensor starting lever 81 by the lever pressing piece 80 is released, so that the sensor starting lever 81 rises due to the urging force of the coil spring 82. Then, since the shielding plate 84 blocks the conduction between the light projecting element 85a and the light receiving element 85b, the infrared sensor 85 can generate an off output.

When the toilet seat body 11 is in the upright state, the control unit F controls the sensor output so as to stop the operation of the sheet paper feeding mechanism unit C, and the sheet paper feeding unit is mistakenly or mischievously. Push button switch
Even if 71 is pressed, the sheet paper P remains the functional part casing.
It is possible to prevent the sheet paper P from being fed out, and it is possible to reliably prevent the entanglement and clogging of the sheet paper P in the functional unit casing 15.

Further, as shown in FIG. 9, in the present embodiment, the rear ends of the toilet seat body 11 are provided with the pivotal support portions 15a, 15 of the functional portion casing 15.
Notches 11a and 11b are formed in conformity with the shape of b. On the other hand, through holes 11c and 11d are provided in the cutouts 11a and 11b.

And, the attachment of the toilet seat body 11 to the functional part casing 15 is
While inserting the functional pivot 13 into the through hole 11c of the cutout 11a, a simple pivot 13a having an enlarged head 13a-1 and a snap tip 13a-2 provided with a slit in the circumferential direction is formed into a cutout.
Through hole 11d provided in 11b and pivot portion 15b of functional unit casing 15
It is performed by penetrating through the through hole 15b-1 provided in the.

With such a configuration, the toilet seat body 11 can be easily attached to the functional portion casing 15 and can be easily removed.

In addition, in this embodiment, the functional pivot 13 having a hollow cylindrical shape is formed.
Has a stainless steel spring pin inside to secure its strength.

Next, the position detecting sensor 70 which detects the position detecting through hole b provided in the sheet paper P and produces an output will be described. As shown in FIG. 3 and FIG. The functional unit casing 15 is provided at a position on the right side of the front portion, and is composed of a light projecting element and a light receiving element, like the infrared sensor 85 of the seating detecting means 72 described above. In addition, it is possible to detect the position detecting through holes 93 which are provided in the sheet paper P at regular intervals.

Then, when the sheet paper P is fed from the sheet paper roll R onto the toilet seat body 11 for a predetermined length by driving the sheet paper feeding mechanism C, the position detecting through hole b is detected by the same position detecting sensor 70. Thus, the operation of the sheet paper feeding mechanism C can be stopped, and the sheet paper P can be accurately supplied and positioned on the toilet seat body 11.

Further, the structure of the sheet paper P will be described with reference to FIG. 13. The sheet paper P is provided with 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 perforations c.

Further, the sheet paper P is provided with a cutout perforation c having a shape adapted to the inner shape of the toilet seat body 11 at a central portion between the perforation c and c for cutting, and along the perforation a for cutout a. An opening communicating with the inside of the flush toilet 10 can be provided by cutting out the sheet paper P by cutting.

However, since the cut-out perforation a is not a complete ring and a non-perforated part d is formed between both ends of the rear part thereof, when the cut-out perforation a is cut off, the cut-out central part is , It hangs down in the flush toilet 10, and the lower end of the flush toilet 10 will get into the accumulated water.

Further, the sheet paper P is provided with position detecting through holes b at one side edge portion corresponding to a portion between the non-perforated portion d and the tip portion of the perforation for cutting a at regular intervals in the longitudinal direction. ing.

Next, the operation of the seat paper automatic feeding toilet seat having the above configuration will be briefly described with reference to FIG.
It becomes as follows.

In the non-energized state, the movable plate 50 inside the functional unit casing 15 has one end thereof, as shown in FIG.
The sheet paper outlet 8a is closed to prevent sewage and the like from entering the sheet paper delivery passage 8 through the sheet paper outlet 8a.

When the flush toilet 10 is used in this state, when the push button switch 71 for feeding the sheet paper is pushed, an operation start signal is input to the control section F, and the sheet paper feeding / cutting order program read from the memory p. Based on the above, the control unit F generates a drive signal, and the drive signal causes the drive motor 41 of the sheet paper cutting mechanism unit D and the sheet paper feeding mechanism unit C to generate a drive signal as shown in FIGS. 14 (a) and 14 (b). The drive motors 40 are sequentially operated.

That is, the movable plate 50 is rotated counterclockwise by the rotation of the disc cam 44 in the clockwise direction by the drive of the drive motor 41.
The sheet paper delivery path 8 communicating with the sheet paper delivery port 8a is formed on the movable plate 50 (first
14 (b)).

After that, the drive motor 40 is driven to feed the sheet paper P from the sheet paper roll R (FIG. 14 (c)).

However, in the above step, when the toilet seat body 11 is in the rotation upright state, the drive motor 40 of the sheet paper feeding mechanism C does not operate and the sheet paper P is not fed. Then, when the toilet seat body 11 is returned to the original horizontal seating position,
It is possible to automatically feed the sheet paper P onto the toilet seat body 11.

Then, the sheet paper P is fed out onto the toilet seat body 11, and then the position detection sensor 70 causes the sheet paper P to move.
When the through hole b provided in the sheet is detected, the drive motor 40 is stopped in the state where the set length sheet paper P is drawn out onto the toilet seat body 11 (Fig. 14 (d)).

At this time, 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.

After that, the drive motor 41 is restarted by the drive signal from the control unit F to move the sheet paper P to the sheet paper pressing piece.
While clamping between 56 and 57 and also between the feeding roller 33 and the pressing roller 34, and when the drive motor 41 continues to drive thereafter, the portion of the sheet paper P located between the both clamping portions has tension in the feeding direction. Will be added (Fig. 14 (e)).

When the drive motor 41 continues to drive, the swing plate
The sheet paper cutting section 58 of 51 removes the sheet paper P from
The sheet paper P is pressed along the perforations c, and the pressing force and the tension in the feeding direction reliably break or cut the sheet paper P (FIG. 14 (f)).

The rear end of the cut sheet paper P is securely clamped by the sheet paper pressing pieces 56 and 57 (Fig. 14 (f)).

After that, when the user sits on the toilet seat body 11, it detects that the seating detection means 72 is seated, and after the urination, when the user leaves the toilet seat body 11, the seating detection means 72 is turned off and the same is turned off. Based on the signal, the control unit F causes the drive motor 41 to
A drive signal is sent and the drive motor 41 is rotated. As a result, the clamp of the sheet paper P is released (14th
(Figure (g)).

After that, remove the sheet paper P of the toilet seat body 11, or
Alternatively, the inside of the flush toilet 10 can be washed by driving the washing device, and the separated portion of the sheet paper P can be taken out along with the washing water and dirt by the force of the washing water.

When the sheet paper position detection sensor 70 detects the removal of the sheet paper P, the drive motor 41 is driven again to close the sheet paper delivery port 8a (Fig. 14 (h)).

That is, the movable plate 50 can take a posture in the functional unit casing 15 that can reliably prevent the invasion of dirty water into the sheet paper delivery path through the sheet paper delivery port 8a.

As described above, the necessary operation, for example, the operation stop of the sheet paper feeding mechanism C can be performed based on the detection output of the toilet seat body standing up detecting means, and the sheet paper feeding operation button switch 71 or the like is operated. Even so, it is possible to reliably prevent the sheet paper P from being fed out onto the toilet seat body 11.

Therefore, it is possible to reliably prevent the accident that the sheet paper P is entangled or jammed in the functional portion casing 15, and it is possible to always ensure a normal sheet paper feeding operation.
