Further, in the present embodiment, the electrical connection between the sheet paper position detecting sensor 70 and the control unit F disposed on the right front portion of the lower casing 16 is as described below.

That is, in FIG. 13, both ends of the substrate 70a which is connected to the upper surface of the paper sheet position detection sensor 70, a pair of lead wires 1 _1, 1 ₂ at one end is connected.

Then, these lead wires 1 _1, 1 _2, as is clear from Figure 10 and Figure 13, the guide shaft 70b, 70c, the right side opening of the protection protrusions 73 through 70d, hanging支機frame 35 It is led out toward the lower part of the right swing arm 37.

Then, the lead wire 1 _1, 1 _2, as shown in FIGS. 10 and 11, distract from bottom to top along the outer surface of the right swing arm 37, through the tubular boss portion 39, the bearing box It is introduced into the interior of the lower casing 31, and then electrically connected to the control unit F disposed on the right front portion of the lower casing 16.

Next, the configuration will be described in detail for introducing the lead wire 1 _1, 1 ₂ from the right swing arm 37 to the bearing box 31 through the tubular boss 39.

As shown in FIG. 8, the cylindrical boss portion 39 is composed of an inner ring 39a and an outer ring 39b which are concentrically projected on the outer periphery of the upper end of the right swing arm.

The inner ring 39a has a wedge portion 39c at its front portion and a plurality of slits 39d in the circumferential direction.

Further, as shown in FIG. 11, the inner ring 39a and the outer ring 39b are provided with notches 39e and 39f at the same circumferential position, and the right swing arm 3 is passed through the notches 39e and 39f.
Lead wires 1 ₁ , 1 ₂ from the outer upper part of 7 to the inside of the cylindrical boss 39.
Can be easily derived.

Therefore, as shown in FIG. 11 and FIG. 12, in order to remove the sheet paper P jammed in the sheet paper feeding mechanism C or the like, the suspension frame 35 is greatly swung, and the sheet paper is accompanied by the swing. even the position detecting sensor 70 swings similarly large, does not move in either little longitudinal direction, the lateral direction in the lead wire 1 _1, 1 ₂ within the cylindrical boss portion 39, thus, functional unit casing 15 It is possible to effectively prevent a wire breakage accident due to sliding contact with each of the parts, a biting accident due to bending, etc., and it is possible to reliably carry out the feeding operation of the sheet paper P, and sufficient electrical safety. Can be secured.

Further, in this embodiment, the lead wire 1 _1, 1 ₂ parts of the cylindrical boss portion 39 is surrounded by a lead protective cover 37a and the protective cable 39g. Therefore, in addition,
It is possible to reliably prevent the cutting or breaking of lead wires 1 _1, 1 _2.

Next, the configuration of the seating detecting means 72 will be specifically described with reference to FIGS. 15 to 18.

As shown in FIG. 15, both ends of the rear portion of the toilet seat body 11 are detachably attached to the pivotal support portions 15a and 15b provided on both front sides of the functional portion casing 15 by the functional pivot 13 and the simple pivot 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.

The functional pivot 13 has a pivot 15 as shown in FIGS.
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. 17, 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 leper pressing piece 80 protruding from the insertion tip thereof, and the lever pressing piece 80 is substantially the same as the axis of the functional pivot 13 as shown in 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 by 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 extra sheet paper P, the signal from the sheet paper position detection sensor 70 can rotate the movable plate 50 so as to block the invasion of dirty water into the sheet paper delivery path 8. it can.

Further, the seating detection means 72 is configured such that, while the user is seated on the valve seat main body 11, the sheet paper P is not drawn out even if the push button switch 71 for drawing out the sheet paper is pressed.

Further, in this embodiment, as shown in FIG. 16 and FIG. 17, the seating detection means 72 is configured to also function as the toilet seat body standing up 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 made considerably larger than the radius of the functional pivot 13, the rotation of the lever pressing piece 80 causes the sensor starting lever 81 to move downward against the urging force of the coil spring 82, thereby shielding it. Since the plate 84 releases the conduction shield 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. 15, in this 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.

Further, the configuration of the sheet paper P will be described with reference to FIG. 19. The sheet paper P is provided with cutting perforations c linearly 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.

Next, the operation of the sheet paper automatic feed toilet seat having the above configuration will be briefly described with reference to FIG. 20.
It becomes as follows.

In the non-energized state, the movable plate 50 in the functional unit casing 15 is, 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 section F generates a drive signal, and the drive signal causes the drive motor 41 of the sheet paper cutting mechanism section D and the sheet paper feeding mechanism section C to generate a drive signal, as shown in FIGS. 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
Figure 20 (b)).

After that, the drive motor 40 is driven to feed the sheet paper P from the sheet paper roll R (FIG. 20 (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 stops in the state where the set length sheet paper P is drawn out onto the toilet seat body 11 (Fig. 20 (d)).

At this time 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.

After that, the drive motor 41 is restarted by the drive signal from the control unit F, and the sheet paper P is pressed against 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 sheet paper P located between the two clamp portions is Means that tension is applied in the feeding direction (Fig. 20 (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 surely breaks the sheet paper P, that is, is cut (FIG. 20 (f)).

Then, the rear end of the cut sheet paper P is securely clamped by the sheet paper pressing pieces 56 and 57 (FIG. 20 (f)).

After that, when the user sits down on the toilet seat body 11, the seating detection means 72 detects that the seating has been performed, and after the urination, when the user leaves the toilet seat body 11, the seating detection means 72 is turned off and the off signal is issued. Based on the above, the control unit F sends a drive signal to the drive motor 41 again to rotate the drive motor 41. As a result, the clamp of the sheet paper P is released (FIG. 20 (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 feed port 8a (FIG. 20 (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, in the present embodiment, when connecting the sheet paper position detection sensor 70 to the control unit F arranged in the functional unit casing 15 using electric wiring such as lead wires, the suspension frame is suspended. The connection is made through the bearing that supports 35.

Therefore, in order to remove the sheet paper P jammed in the sheet paper feeding mechanism C and the like, the suspension frame 35 is largely swung, and the sheet paper position detection sensor is accompanied by the swing.
Even if the 70 swings largely similarly, the electric wiring hardly moves in the bearing portion in either the front-rear direction or the left-right direction. Therefore, a disconnection accident due to a sliding contact with each part of the functional unit casing 15 or In addition, it is possible to effectively prevent a biting accident due to bending, to reliably perform the sheet paper feeding operation, and to sufficiently secure electrical safety.
