The connection plug 72 is prevented from being pulled out by the left and right side walls 65, 66 on the cover casing 60.

The pressing roller 71 comes into contact with the feeding roller 24 attached to the sheet paper feeding shaft 23 of the sheet paper feeding mechanism C described above in a pressed state, and the gear 74 fixed to one end of the holding roller 71 feeds the sheet paper. It meshes with a gear 73 fixed to the corresponding end of the shaft 23.

With this configuration, when the sheet paper feeding shaft 23 and the feeding roller 24 rotate in one direction, the pressing roller 71
Can rotate in the opposite direction via the gears 73 and 74, and can feed out the sheet paper P from the sheet paper roll R.

Also, an O-ring 71b is similarly attached to the holding roller 71 in accordance with a predetermined position of the feeding roller 24,
The occurrence of idling, slippage and kinking when the sheet paper P is fed out is effectively prevented.

Further, as shown in FIG. 5, both ends of the pressing roller 71 have a base end on the lower front side of an L-shaped sheet paper roll replacement opening / closing lid 70c forming a front wall of the sheet paper roll storage box 70, and a vertical direction. The swing lever 71a is pivotally supported by the tip of a swing lever 71a which is pivotally supported by the swing lever 71a.

The pressing roller 71 uses a material roller having a high specific gravity in order to press and contact the feeding roller 24 and to reliably feed the sheet paper P from the sheet paper roll R.

With this configuration, the pressing roller 71 comes into pressure contact with the feeding roller 24 by its own weight. Further, since the pressing roller 71 can swing to the outside, the attachment / detachment of the sheet paper roll R to / from the sheet paper roll storage box 70 becomes easy.

Further, as shown in FIG. 5, between the upper wall 60c of the cover casing 60 and the lower end of the sheet paper roll replacement opening / closing lid 70c of the sheet paper roll storage box 70,
A sheet paper extracting slit 75 is formed.

Accordingly, the sheet paper P unwound from the sheet paper roll R in the sheet paper roll storage box 70 is
Is, as shown in FIG.
After being bent outward by the curling of the sheet paper roll R, the sheet paper roll R passes between the pressing roller 71 and the feeding roller 24, and then the sheet paper removing slit is formed.
Through 75, it is fed out onto the toilet seat body 11.

Note that the sheet paper roll storage box 70 and the above-described cover casing 60 are integrally formed to form the functional unit casing H.

Next, the sheet paper P will be described. As shown in FIGS. 5 and 6, the sheet paper P forms a part of the sheet paper roll R, and is used after being cut.

The reason why the sheet paper P is formed from the sheet paper roll R is that the sheet paper P for a large number of people is compactly stored in the functional section casing H provided behind the toilet seat body 11, and This is for automatically and accurately feeding out to the upper surface of the main body 11.

Further, as shown in FIGS. 2 and 6, the sheet paper P is provided at a predetermined interval in the center thereof at predetermined intervals in the longitudinal direction, and a cutout perforation having a shape adapted to the inner shape of the toilet seat body 11. An opening communicating with the interior of the flush toilet 10 can be provided along the perforation 80.

However, the perforation 80 is not completely annular, and the non-perforated portion 81 is formed between both ends of the rear portion. Therefore, when the perforation 80 is cut off, the cut-out central portion is inside the flush toilet 10. , And its lower end will be pooled and immersed in water.

Further, the sheet paper P is not completely perforated and the non-perforated portion 81 and the cutout perforated 80 are provided.
If perforated, the waist will be lost and sheet paper P
This is because it is almost impossible to bend or form the sheet paper roll R when supplying the sheet onto the toilet seat body 11. That is, the sheet paper P provided with the perforations 80 and the non-perforated portions 81 has sufficient stiffness, and both automatic feeding and roll processing can be easily performed.

Further, the perforations 80 of the sheet paper P can prevent the sheet paper P from being entangled in the feeding roller 24 and the pressing roller 71 at the time of feeding.

Also, the perforation 80 for cutting out the sheet paper P
Perforations may be formed entirely in the shape adapted to the inner shape of the toilet seat body 11, or perforations may be provided in some places, and others may be cut.

Further, as shown in FIG. 2 and FIG. 6, the sheet paper P is provided at regular intervals in the longitudinal direction at a non-perforated portion 81.
And a front end of the perforation 80, a through hole 82 for position detection is provided, while the cover casing 60 corresponding to the through hole 82 is provided.
Is provided with a position detection sensor 83 at the center thereof.

The position detecting sensor 83 detects the through hole 82 when the sheet paper P has been fed out of the sheet paper roll R by a predetermined length, stops the operation of the sheet paper feeding mechanism C, and corrects the position. Then, the sheet paper P can be supplied and positioned on the toilet seat main body 11.

In place of the through holes 82, a desired coloring mark may be provided on the sheet paper P. Further, the mounting positions of the through holes 82 and the like are not limited to the central portion of the sheet paper P, but may be any positions. be able to.

Further, the supply and positioning of the sheet paper P does not use the position detection sensor 83, and the rotation motor
The number of rotations of 30 can be counted by a desired counter, and the control unit F can be operated based on the same coefficient value.

In FIG. 2, reference numeral 84 denotes a seating sensor comprising a reflection type infrared sensor provided at a front end of one end of the mounting board 20,
After the user sits on the toilet seat body 11, a certain period of time (for example,
After a lapse of 10 seconds, a detection signal is generated when the user separates from the toilet seat body 11, and the control unit F is operated to cut the sheet paper P instantaneously by reciprocating the cutting blade 28 in the axial direction. It is to let.

It should be noted that the seating sensor 84 can be integrated with the sheet paper automatic supply toilet seat A or can be separated and formed separately, depending on the use conditions and use environment.

Further, in addition to the seating sensor 84, the load at the time of sitting is detected by a load cell or the like, and the control unit F is operated to activate the seat paper P.
Can also be cut.

In FIG. 2, reference numeral 85 denotes a rotation motor via the control unit F when detection is removed from the toilet seat body 11 when the toilet seat body 11 is in a state where it cannot be seated (when the toilet seat body 11 is self-standing). An abnormal feeding prevention sensor for stopping the supply of the sheet paper P by cutting off the power supply to the
Only when the seat is in a seatable state, the toilet seat main body 11 is detected to be in an operable state.

Note that a micro switch, a limit switch, or the like can be used instead of the sensor 85.

Further, in this embodiment, as shown in FIG. 5, in conjunction with the opening operation of the sheet paper roll replacement opening / closing lid 70c which forms a part of the functional unit casing H and can be opened and closed around the pivot 70d. It is also characterized by including a safety device SD for stopping power supply from a power supply PS to be described later to the sheet paper feeding mechanism C, the sheet paper cutting mechanism D, the controller F and the like.

Here, the safety device SD includes opening / closing detection means for detecting opening / closing of the sheet paper roll box 70 as a housing, and the sheet paper roll box 70
And an operation stopping means for stopping the operation of the sheet paper driving mechanism C and the like when detecting that the sheet is open.

In FIG. 5, the above-mentioned open / close detection means is shown as a normally closed contact micro switch provided on the rear wall of the sheet paper roll storage box 70, and interlocks with the opening / closing operation of the sheet paper roll replacement open / close lid 70c. Thus, the contact of the above-mentioned operation stopping means can be made an open contact to cut off the power supply.

That is, in FIG. 9 showing an example of a control circuit and a power supply circuit for controlling the operation of the sheet paper automatic supply toilet seat A,
110 is an input interface interposed between the control unit F and the sheet paper feeding push button 61, the position detection sensor 83, the seating sensor 84, the sheet paper abnormality feeding prevention sensor 85, etc., and 111 is the input interface The output interface is provided between the sheet paper feeding mechanism C and the sheet paper cutting mechanism D.

Then, the above-mentioned sheet paper feeding push button 61

A safety device SD is provided in the middle of the current supply line 112. The safety device SD is activated by the opening operation of the sheet paper roll replacement opening / closing lid 70c, and the sheet paper feeding push button. 61 ・ Position detection sensor 83
・ Seat sensor 84 ・ Seat paper abnormal feeding prevention sensor 85
Control unit F, sheet paper feeding mechanism C, sheet paper cutting mechanism D, input / output interfaces 110, 111
Etc., can be stopped.

Therefore, in the replacement work of the sheet paper roll R, it is possible to reliably prevent accidents such as accidentally winding a finger into the sheet paper feeding mechanism C or cutting a finger by the sheet paper cutting base rear portion D. The safety of the replacement operation of the paper roll R can be significantly improved.

In the embodiment of FIG. 5, as the safety device SD,
Although a microswitch is used, other contact-type sensors and non-contact-type sensors can also be used.

Hereinafter, the operation of the sheet paper automatic supply toilet seat A having the above configuration will be described with reference to the flowchart shown in FIG.

First, the power is turned on by the power switch S, and it is checked whether the power lamp 62 is lit (100).

The power switch S is provided on the back surface at one end in front of the mounting board 20 because it is not particularly required during use (see FIG. 4).

After checking, the push button 61 for feeding the sheet paper is pressed (101).

At this point, if there is no paper jam or sheet paper roll R, the paper jam lamp 64 or the paper supply lamp 63 of the operation unit G is turned on (102) (103).

When there is no paper jam and the sheet paper roll R is sufficient, or when the paper jam is eliminated or the sheet paper roll R is moved to the sheet paper roll storage box 70,
And when the toilet body 11 is not in an independent state and the abnormal feeding sensor 85 does not operate,
The control unit F operates to drive the rotation motor 30 and also drive the clutch mechanism M to select a gear train to be connected to the feeding roller 24 and the pressing roller 71.

Thereby, the forward rotation of the rotation motor 30 is transmitted to the feeding roller 24 and the pressing roller 71 via the gear trains 32, 33, 34, 35, 36. By the way, since the feeding roller 24 and the pressing roller 71 rotate in the opposite directions to each other and hold the sheet paper P in a pressed state, the sheet paper P is stored in the sheet paper roll R in the sheet paper roll storage box 70. Will be unwound from.

That is, as shown in FIG. 5, the sheet paper P is once bent in the reverse winding direction by the pressing roller 71 and the curling of the sheet paper roll R is returned, and then the sheet paper P is moved between the feeding roller 24 and the pressing roller 71. As a result, the sheet is then fed and supplied onto the toilet seat body 11 through the sheet paper take-out slit 75.

In addition, in the feeding operation, when the sheet paper P is fed out onto the toilet seat main body 11 by a predetermined length, the position detection sensor 83 detects the position detection through hole 82 provided in the center portion of the sheet paper P, and Then, the control unit F is operated to stop the rotation of the rotation motor 30. With this, the feeding roller
Feeding of sheet paper P by 24 and holding roller 71
The feeding operation is also stopped instantaneously, and the sheet paper P is fed out onto the toilet seat main body 11 exactly by a predetermined length (104).

In addition, although the sheet paper R at the stage of being unwound from the sheet paper roll R is curled in the winding direction, in the present embodiment, the curling of the sheet paper P in the above winding direction is returned by the pressing roller 71. After that, the paper can be sent out onto the toilet seat body 11 through the paper removal slit 75.

Accordingly, it is possible to reliably prevent a paper jam accident in which the sheet paper P is curled in the winding direction and is sent out only to the inside of the functional unit casing H and is not supplied onto the toilet seat main body 11. Can be prevented from being curled near the paper take-out slit 75 without being fed to a predetermined position.

Thereafter, the user cuts off the central portion of the sheet paper P along the perforations 80 leaving only the non-perforated portions 81, hangs the cut portion downward, and attaches the tip of the cut portion to the pool water in the flush toilet 10.

As described above, in the present embodiment, the sheet paper P can be supplied onto the toilet seat main body 11 by a predetermined length by a one-touch operation. Moreover, in this state, since the sheet paper P is not cut from the sheet paper roll R, there is no need to worry about falling off from the flush toilet 10 or to perform positioning.

Further, by operating the lock mechanism (not shown) and the control unit F, even if the sheet paper feed-out push button 61 is pressed while the supply of the sheet paper P is completed, the next sheet paper P is not fed out / supplied. Therefore, consideration is given to prevention of mischief and determination of whether or not use is possible.

Thereafter, the user sits on the sheet paper P on the toilet seat body 11 (105).

When the user sits on the toilet seat body 11 and stands up from the toilet seat body 11 after stool (106), the seating sensor 84 detects that the user has left the toilet seat body 11, and the control unit F is activated by the detection signal. Actuates to rotate the rotation motor 30 in the reverse direction,
By operating the clutch mechanism M, the rotating motor 30 is connected to the cutting blade moving shaft 25 via the gear train gears 31, 32, 32a, 39, and 38, and the cutting blade 28 is reciprocated to move the sheet paper P. Disconnect momentarily (107).

Then, in the above operation, as described above, for example, as long as the seat sensor 84 does not sense continuously for 10 seconds (that is, unless the user is continuously seated for 10 seconds), the user can move the seat sensor 84 from the toilet seat body 11 as described above. The control unit F cannot be operated even if it stands up.

Therefore, consideration is given to preventing the cutting operation of the sheet paper P due to erroneous sensing such as detecting the sheet paper P being fed out or detecting the instantaneous operation of the user other than sitting.

The set timing of the seating sensor 84 and the time lag for countermeasures against malfunction can be set according to the environment by the control unit F.

After that, the cleaning device is driven to clean the inside of the flush toilet 10,
The cutoff portion of the sheet paper P can be taken in and discharged together with the washing water and the waste by the water force of the washing water (108).

In the use of a public (public place) such as a theater, the control is performed so that the sheet paper P is automatically supplied to the toilet seat body 11 for the next user after the above-described series of operations is completed. It is also possible to activate part F.

With the configuration and operation described above, this embodiment has the following effects.

That is, the sheet paper roll R is provided by the safety device SD.
Even if the operation buttons are accidentally pressed when replacing the
By using the SD, it is possible to cut off the power supply to the sheet paper feeding mechanism C, the sheet paper cutting mechanism D, the control unit F for controlling them, and various operation buttons in the operation unit G. In operation, it is possible to reliably prevent accidents such as a finger being accidentally entangled in the sheet paper feeding mechanism C or a finger being cut by the sheet paper cutting mechanism D, and the safety of the sheet paper roll replacement operation is reduced. It can be significantly improved.

In the above-described embodiment, the cutting of the sheet paper P is performed by the disk-shaped sharp cutting blade 28. However, the sheet paper P is cut in a direction perpendicular to the feeding direction at a predetermined interval in the feeding direction of the sheet paper P. It is also possible to provide a perforation, clamp both sides of the perforation, apply a pressing force from above or below with a rounded pressing blade or the like, and cut the perforation by breaking.
