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.

The sensor starting lever 81 is supported in a lever lifting guide casing 83 having a coil spring 82 built-in in a base end portion 81a so as to be lifted and lowered in an upwardly biased state, and has a shield member at a tip portion 81b thereof. A shielding plate 84 is projected.

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.

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 resists the urging force of the coil spring 78 and the functional pivot 13, the movable bearing 77 and The lever pressing piece 80 is integrally lowered, and the sensor starting lever 81 is also lowered in conjunction with the lowering, and the shield plate 84 releases the conduction shield between the light projecting element 85a and the light receiving element 85b, so that the infrared sensor 85 is turned on. Output can be generated.

On the other hand, when the toilet seat body 11 is returned to the horizontal seating position from the upright position, the pressing force of the lever pressing piece 80 on the sensor starting lever 81 is released, so the biasing force of the coil spring 78 causes the functional pivot 13, movable bearing. 77 and the lever pressing piece 8 are integrally lifted, and the sensor starting lever 81 is also lifted by the biasing force of the coil spring 82 in conjunction with the lifting, and the shield plate 84 connects the light projecting element 85a and the light receiving element 85b. Since it is cut off, the infrared sensor 85 can generate an off output.

When the toilet seat main body 11 is in the upright state, the sensor output stops the operation of the sheet paper feeding mechanism C, and even if the sheet paper feeding button switch 71 is pressed by mistake or The paper P is fed out onto the toilet seat body 11, and it is possible to reliably prevent the sheet paper P from being entangled or jammed in the functional unit casing 15.

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 a having a shape adapted to the inner shape of the toilet seat body 11 in the central portion between the perforation c and c for cutting, and along the perforation a for cutout. 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.
