Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to an automatic sheet paper supplying toilet seat.

(B) Prior Art Conventionally, the following methods and devices for setting sheet paper on a toilet seat have been known in consideration of hygiene.

In this method, sheet paper is folded into four and stored in a paper holder hung on the wall, and is taken out one by one, unfolded, and set on the toilet seat.

This is a device as described in Japanese Utility Model Publication No. 55-179600, in which a storage box for storing sheet paper rolls is provided on the toilet lid, and the sheet paper can be pulled out from the storage box onto the toilet seat. In addition, the sheet paper is characterized by a configuration in which the sheet paper can be pressed and held in conjunction with seating, and the sheet paper can be separated one by one.

This is a device as described in Japanese Utility Model Application No. 60-155399, and the device is shaped into a size and shape that can cover the top surface of the toilet seat, and
It consists of a sheet-like paper holder that stores a continuous sheet of paper by winding it up or folding it, and continuously feeding out the paper, and a paper feeding side of the holder that stores the paper in a predetermined manner. a paper feed-out cutting section that is equipped with a feed roller for feeding the length of the paper forward near the top surface of the toilet seat, and a cutting blade that cuts the rear end of the paper of a predetermined length that has been fed; It is characterized by its structure.

This is a device as described in Japanese Patent Publication No. 57-29174, in which a tube feeding device is placed near one end of the seat, and a tube picking device is placed near the other end.
The tube is stored in a feeding device, and is characterized by having a drive device for the picking up device and a switch connected thereto, so that the tube is moved by operating the switch.

(c) Problems to be solved by the invention However, the conventional methods and devices described above,
It still had the following problems.

(b) First, with the first method, there is no means for holding the sheet paper on the toilet seat, so even if you try to cover the toilet seat with the sheet paper, the sheet paper will slip and fall immediately. Coating work is extremely difficult.

In addition, since the sheet paper is not held on the toilet seat, it cannot be accurately positioned on the toilet seat due to the influence of the weak moving wind pressure caused by the air.
Difficult to handle.

In addition, since it is stored in a folded state,
When unfolded and used, the sheet paper bends from the fold, easily falls off, and does not sit stably on the toilet seat.

Furthermore, after using the toilet, the sheet paper clings to the buttocks, making it uncomfortable.

(b) Regarding the second device, the work of feeding and feeding the sheet paper to the toilet seat had to be done manually, causing inconvenience to the user.

Furthermore, depending on how the user sits, it may not be possible to reliably cut the sheet paper.

In addition, the sheet paper is fed out manually, and some users may not stop it at the specified position, and the cutting perforation may not be located at the appropriate position and may move. cannot cut sheet paper.

Furthermore, the sheet paper is always exposed from the ejection port by the length required to partially draw it out.
It is considered unsanitary because water or sewage may adhere to it, and it is also something that can be touched by hands.

(c) Regarding the third device, the sheet paper feeding operation is performed simply by turning on and off the feeding switch, and is not performed via the control device, so the sheet paper feeding operation is performed each time. The feeding lengths are different, and it is not always possible to accurately feed out a predetermined length. Also, the cutting operation is performed by turning the cutting switch on and off.
Since it is not performed automatically via a control device, it lacks operability. Furthermore, since the sheet paper roll, feeding roller, etc. are configured separately from the toilet seat, they take up installation space and make the space of the toilet etc. narrow.

(d) Furthermore, regarding the fourth device, the tube is made of plastic film to prevent damage when the tube is fed out, and is uncomfortable to the touch when seated. In addition, since the tube is moved and rolled up between the tube feeding device and the tube take-out device, it is impossible to determine whether the tube on the toilet seat is a tube before use or a tube after use. The person must move the tube before sitting, and if the tube is not used yet, it will be wasted.

Furthermore, the toilet seat is supported in a so-called cantilever shape, and one side of the seat is dangling, which weakens its strength.

Furthermore, if the toilet seat is made too heavy, the plastic film may be under pressure between the toilet bowl and the toilet seat, making it inoperable.

Furthermore, it cannot be used with front-split type toilet seats.

Furthermore, the used tube is rolled up and stored in the casing, which is unsanitary.

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 Problems The present invention provides a sheet paper roll and a sheet for feeding the sheet paper from the sheet paper roll onto the top surface of the toilet seat body, in a functional casing provided at the rear of the toilet seat body. a paper feeding mechanism section, a sheet paper cutting mechanism section that cuts the rear end of the sheet paper fed out onto the toilet seat main body, a sheet paper holding mechanism section that holds the rear end of the sheet paper, and the same sheet paper feeding mechanism section; Control that integrally controls a sheet paper cutting mechanism section and a sheet paper holding mechanism section to feed out a set length of sheet paper onto the toilet seat body, cut the rear end of the sheet paper, and hold the rear end of the cut sheet paper. The present invention relates to an automatic sheet paper supply toilet seat characterized in that a control section and an operation section for operating the control section are integrally housed and arranged.

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

Since the sheet paper feeding mechanism section, the sheet paper cutting mechanism section, and the sheet paper holding mechanism section are operated by the control section, the sheet paper is automatically and accurately fed out by a certain length onto the toilet seat body. The rear end of the sheet paper can be cut, and the rear end of the cut sheet paper can be securely held.

In this way, the fed sheet paper is held in a cut state, so for example, when used in a public place, a large number of sheet papers wound around a sheet paper roll may be intentionally or mischievously cut into pieces. Even if an attempt is made to pull out the sheet paper further, only one sheet of paper that has already been fed out can be pulled out, and continuous removal of the sheet paper due to mischief or the like can be reliably prevented.

In addition, after the sheet paper is cut, the sheet paper can be held securely by the sheet paper holding mechanism, which can reliably prevent the sheet paper from falling off the toilet seat due to a breeze. You can easily use the toilet without worrying about it falling, and the usability can be improved.

In the functional part casing provided at the rear of the toilet seat body, a sheet paper roll, a sheet paper feeding mechanism part, a sheet paper cutting mechanism part,
A sheet paper holding mechanism section, a control section that controls the sheet paper feeding mechanism section, the sheet paper holding mechanism section, and the sheet paper cutting mechanism section, and an operation section that operates the control section are integrally arranged and housed. Therefore, the multi-functional toilet seat structure can be made compact overall, the usable space of the toilet can be maximized, and the usability can be improved.

Furthermore, due to its compact form, it can be installed in any toilet bowl, and can also be attached to an existing toilet bowl, in which case it can be easily replaced with an existing toilet seat.

(f) Examples The present invention will be described in detail below based on examples shown in the attached drawings.

FIG. 1 shows the overall configuration of a toilet device B equipped with an automatic sheet paper supplying toilet seat A according to the present invention.
0 so that it can be opened and closed vertically.

The structure of the automatic sheet paper supply toilet seat A will be explained in detail with reference to FIGS. 2 to 5.

As shown in the figure, the sheet paper automatic supply toilet seat A includes a toilet seat main body 11 placed on the flush toilet bowl 10 so as to be openable and closable, and a toilet seat main body 11 placed in a fixed state on the rear part of the flush toilet bowl 10, and a toilet seat main body 11 on the front part. Pivot the rear part of

As shown in FIGS. 2 to 5, the functional unit 13
is an L-shaped mounting board 20 that is attached to the rear of the flush toilet 10 and has one end of a rectangular plate bent at a right angle toward the front of the toilet seat body 11 when viewed from above.
It is formed of a sheet paper feeding mechanism section C, a sheet paper cutting mechanism section D, a sheet paper holding mechanism section I, a sheet paper roll storage section E, a control section F, and an operation section G, which are mounted on the same mounting board 20. There is.

First, the configurations of the sheet paper feeding mechanism section C, sheet paper cutting mechanism section D, and sheet paper holding mechanism section I will be explained.
As is clear from the figure, the mounting board 20 has rotary shaft support plates 21 and 22 erected on both ends thereof.
Between the support plates 21 and 22, a plurality of rotating shafts are rotatably supported horizontally.

That is, 23 is a sheet paper feeding shaft that is horizontally suspended between the upper front ends of the support plates 21, 21, and a large number of feeding rollers 24 are attached to the feeding shaft 23 at predetermined intervals in the axial direction.

The feeding roller 24 cooperates with a pressing roller 71, which will be described later, to press and clamp the drawn end of the sheet paper P and transfer the sheet paper P from the sheet paper roll storage section E to the toilet seat main body 11.
It can be fed upwards and fed.

In addition, since the large number of feeding rollers 24 are arranged in the axial direction at predetermined intervals, the sheet paper P can be fed out at the same speed and with a uniform pressing force over the entire width, and the sheet paper P
This effectively prevents the occurrence of kinks.

In addition, O-rings 24a are attached to all of the many feeding rollers 24 to prevent idle rotation and slippage when feeding the sheet paper P.
Note that such idling and slipping can be prevented by making the feeding roller 24 itself made of rubber, or by using a rubber belt or the like.

Further, in FIGS. 4 and 5, 25 is a cutting blade moving shaft formed from a screw rod and horizontally suspended between the lower front ends of the support plates 22, 22. A formed cutting blade movement guide shaft 26 is provided.

A cutting blade mounting plate 27 is attached to the cutting blade moving shaft 25 and the cutting blade moving guide shaft 26, and the mounting plate 27 is screwed onto the cutting blade moving shaft 25.

Further, a disk-shaped cutting blade 28 is rotatably supported on the upper end of the cutting blade mounting plate 27.

With this configuration, when the cutting blade moving shaft 25 is rotated, the cutting blade 28 reciprocates in the axial direction together with the cutting blade mounting plate 27, and the sheet paper P can be cut instantly.

In addition, instead of the above-described structure, the mechanism for moving the cutting blade 28 can be made such that an endless wire or an endless belt is driven by a rotary motor so that it can reciprocate in the left and right width direction, and the cutting blade 28 is moved on the endless wire or the like. It can also be configured by binding.

In addition, a method of cutting the sheet paper P by reciprocating the cutting blade 28 is performed by rotating rotating shafts 93 and 94 each having a cutting blade 90 and a cutting blade receiving groove 91 as shown in FIGS. 7 and 8. By doing so, it is also possible to cut the sheet paper P. At this time, the above-mentioned cutting by rotation at 180° can be changed to an arbitrary angle.

7 shows the rotating shafts 93, 94 in a state where the sheet paper P is fed, and FIG. 8 shows the rotating shafts 93, 94 in a state where the sheet paper P is cut. Further, 95 and 96 indicate a holding roller and a feeding roller, respectively.

Further, in the embodiment, the cutting blade 28 is shaped like a disc in consideration of durability, but it can also be shaped like a flat plate.

Next, the configuration of the sheet paper holding mechanism section I will be explained with reference to FIGS. 4 and 5.

As shown in the figure, the sheet paper holding mechanism I is provided at a constant distance from the sheet paper cutting mechanism D toward the toilet seat body 11.

The sheet paper holding mechanism I includes a pair of upper and lower holding rollers 97a and 97b that can press and hold the sheet paper P from both sides thereof. Both holding rollers 97a and 97b are
Both ends are pivotally supported by brackets 97c and 97d projecting inside the sheet paper roll storage box 70 and cover casing 60, which will be described later.

With this configuration, the rear end of the sheet paper P cut by the sheet paper cutting mechanism D can be held by being pressed.

In addition, in FIGS. 2 and 4, 30 is the sheet paper feeding shaft 23 and the cutting blade moving shaft 25.
is a rotary motor that can be selectively rotated via a clutch mechanism M, and the clutch mechanism M
Switching between the sheet paper feeding shaft 23 and the cutting blade moving shaft 25 is performed by switching the rotary motor 30 between forward and reverse rotation. In addition, in this embodiment, the rotation motor 30 is connected to the one side support plate 2.
It is fixed at 1.

The rotational force is transmitted from the rotary motor 30 to the sheet paper feeding shaft 23 by the rotary motor 30.
This is accomplished by transmitting the rotation of the gear 31 fixed to the output shaft of the sheet paper through gear trains 32, 33, 34, 35, and 36 to the gear 37 fixed to the sheet paper feeding shaft 23.

On the other hand, the rotational force from the rotary motor 30 to the cutting blade moving shaft 25 is transmitted to the cutting blade moving shaft 25 by a gear 38.
and the gear 3 is fixed by the clutch mechanism M.
This can be done by releasing the gear 32 that meshes with the gear 38 from the mesh by reversing the rotating motor 30, and also meshing the gear 38 with the gear 39 that meshes with the gear 32a that is integrated with the gear 32.

That is, the rotational force of the rotary motor 30 is transmitted through the gears 31,
It is transmitted to the cutting blade moving shaft 25 via 32, 32a, 39, and 38.

With this configuration, the single rotary motor 30 is driven by the operation of the clutch mechanism M, and the feeding operation of the sheet paper P and the feeding operation of the sheet paper P are performed by driving the rotary motor 30 in forward and reverse directions. The cutting operation can be performed selectively and sequentially.

However, the feeding operation and the cutting operation can also each be performed using dedicated motors.

Note that the rotational force of the rotary motor 30 can be transmitted to the sheet paper feeding shaft 23 and the cutting blade moving shaft 25 using a belt or a wire instead of using a gear train.

Further, to explain the drive structure of the sheet paper holding mechanism part I, in FIG. Sprocket wheel 97f and endless chain 9 fixed to the shaft end of
connected by 7g.

With this configuration, the sheet paper feeding shaft 2
3, the upper and lower holding rollers 97a, 9
7b can also rotate to feed out the sheet paper P, and when the driving of the sheet paper feeding shaft 23 is stopped, the upper and lower holding rollers 97a and 97b also stop their rotation, and the rear end of the sheet paper P after cutting is stopped. The sheet paper P can be held securely by pressing and clamping.

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 the sheet paper holding mechanism section I will be explained.

As shown in FIGS. 2 and 4, the mounting board 20

A control unit mounting plate 50 is provided upright, and a control panel 51 for controlling the operation of the above-mentioned rotation motor 30 is attached to the control unit mounting plate 50, forming a control unit F. are doing. Note that a transformer 51a is also integrally attached to the control panel 51.

Further, a sheet paper feeding mechanism section C, a sheet paper cutting mechanism section D, a sheet paper holding section I, and a control section F are arranged on the mounting board 20 described above.
is integrally surrounded by an L-shaped cover casing 60 having the same outer shape as the mounting board 20.

Next, the operation part G will be explained. As is most obvious from FIG. , a sheet paper feeding push button 61 on the top surface of the operation unit mounting plate 59 disposed inside the cover casing 60;
A power lamp 62 consisting of a light emitting diode, etc., a paper replenishment lamp 63 having a warning function in the event of an abnormality such as a paper jam or paper replenishment, and a paper jam lamp 6.
It is constructed by attaching 4 etc.

Note that a buzzer or the like may be installed instead of the paper replenishment lamp 63 or the like.

Further, above the sheet paper feeding mechanism section C, a sheet paper roll storage section E is provided, as shown in FIGS. 3, 4, and 5.

And the sheet paper roll storage section E
A sheet paper roll storage box 70 is removably attached to the space formed between the left and right side walls 65 and 66 that are integrally provided on the left and right upper surfaces of the cover casing 60, and a sheet paper roll storage box 70 is provided inside the storage box 70 to replace the sheet paper roll storage box 70. It is formed from the attached sheet paper roll R and a pressing roller 71 horizontally suspended in front of the lower part of the sheet paper roll storage box 70.

In the above configuration, the sheet paper roll storage box 70 has both left and right end walls 70
a, 70b are provided with openings that communicate with openings at both ends of the center axis of the sheet paper roll R, and within the openings are connection plugs 72 that rotatably and removably connect the sheet paper roll R to the left and right end walls 70a, 70b. By moving the connecting plug 72 back and forth in the axial direction, the sheet paper roll R can be easily connected and removed.

Note that the connection plug 72 is connected to the cover casing 6
The right and left end walls 65 and 66 on the top of the 0 prevent the device from coming off.

Further, the press roller 71 is connected to the sheet paper feeding shaft 2 of the sheet paper feeding mechanism section C described above.
A gear 74 that is in pressure contact with the feed roller 24 attached to the sheet paper feed roller 3 and is fixed to one end of the press roller 71 is meshed with a gear 73 that is fixed to the corresponding end of the sheet paper feed shaft 23.

With this configuration, the sheet paper feeding shaft 2
3 and the feed roller 24 rotate in one direction, the press roller 71 rotates in the opposite direction via gears 73 and 74, and the sheet paper P can be fed out from the sheet paper roll R.

Additionally, an O-ring 71b is attached to the presser roller 71 in a similar manner to match the predetermined position of the feed roller 24.
is installed to effectively prevent the occurrence of idle rotation, slipping, and twisting when sheet paper P is fed out.

Further, as shown in FIG. 5, both ends of the pressing roller 71 are pivoted to the tip of a swinging lever 71a whose base end is pivoted to the lower part of the front wall of the sheet paper roll storage box 70 so as to be swingable in the vertical direction. It is freely supported.

Further, the press roller 71 is the feed roller 2
A roller made of a material with a heavy specific gravity is used in order to make pressure contact with the roller 4 and reliably feed out the sheet paper P from the sheet paper roll R.

With this configuration, the pressing roller 71 is
Due to its own weight, it comes into pressure contact with the delivery roller 24. In addition, since the pressing roller 71 can swing outward, the sheet paper roll storage box 70 of the sheet paper roll R
Easy to install and remove.

Further, as shown in FIG. 5, there is a space between the upper wall 60c of the cover casing 60 and the lower end of the front wall 70c of the sheet paper roll storage box 70.
A slit 75 for taking out sheet paper is formed.

Therefore, sheet paper roll storage box 7
As shown in FIG. 5, the sheet paper P unwound from the sheet paper roll R in 0 is bent outward by the presser roller 71 to uncurl the sheet paper roll R, and then the sheet paper P is unwound by the presser roller 71. Roller 71 and feeding roller 24
and between the upper and lower holding rollers 97a and 97b, and then the sheet paper ejection slit 75.
Through this, it is drawn out onto the toilet seat main body 11.

In addition, sheet paper roll storage box 70
and the above-mentioned cover casing 60 together form a functional part casing H.

Next, to explain sheet paper P,
As shown in FIGS. 4 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 can be stored compactly in the functional part casing H provided at the rear of the toilet seat body 11. This is to enable automatic and accurate feeding onto the upper surface of the holder 11.

In addition, as shown in FIGS. 2 and 6, the sheet paper P has cutout perforations in the center thereof at predetermined intervals in the longitudinal direction and having a shape that matches the inner shape of the toilet seat body 11. 80, and an opening communicating with the inside of the flush toilet 10 can be provided along the perforation 80.

However, the perforation 80 is not completely annular, and a non-perforation part 81 is formed between the rear ends of the perforation 80, so when the perforation 80 is cut out, the cut out central part is inside the flush toilet bowl 10. The bottom end will be submerged in standing water.

In addition, the sheet paper P is not completely perforated, and the non-perforated part 81 and the perforated part 8 for cutting out
The reason why 0 is provided is that if the sheet paper P is provided with holes, it will not have any stiffness, and when feeding the sheet paper P onto the toilet seat body 11, it will not bend and it will be almost impossible to form the sheet paper roll R. This is because. On the other hand, the sheet paper P provided with perforations 80 has sufficient stiffness and can easily be both automatically fed and rolled.

Further, the perforations 80 of the sheet paper P can prevent the sheet paper P from being caught in the feeding roller 24 and the press roller 71 as much as possible during feeding.

Further, the perforations 80 for cutting out the sheet paper P can be made into perforations throughout the sheet paper P in a shape that matches the inner shape of the toilet seat main body 11.
It is also possible to provide perforations here and there and make cuts elsewhere.

Further, as shown in FIGS. 2 and 6, the sheet paper P is inserted between the non-perforated portion 81 and the tip of the perforation 80 at regular intervals in the longitudinal direction. On the other hand, a position detection sensor 83 is provided in the center of the cover casing 60 corresponding to the through hole 82.

The position detection sensor 83 detects the through hole 82 when the sheet paper P is fed out a predetermined length from the sheet paper roll R, stops the operation of the sheet paper feeding mechanism section C, and accurately The sheet paper P is supplied and positioned on the toilet seat body 11, and the control section F is activated to reciprocate the cutting blade 28 in the axial direction, thereby instantaneously cutting the sheet paper P.

Note that instead of the through holes 82, desired colored marks may be applied to the sheet paper P, and furthermore, the attachment positions of the through holes 82, etc.
It can be placed not only at the center but also at any desired location.

Further, the above-mentioned supply and positioning of the sheet paper P is performed by counting the number of revolutions of the rotary motor 30 with a desired counter, without using the above-mentioned position detection sensor 83, and operating the control section F based on the counted value. You can also do it by

Further, in FIG. 2, reference numeral 84 denotes a seating sensor consisting of a reflective infrared sensor provided at the front of one end of the mounting board 20, which detects the standing motion of the user from the toilet seat body 11 and uses the detection signal to detect the position. , it is also possible to operate the control unit F to release the pressure holding force between the upper and lower holding rollers 97a and 97b, so that the sheet paper P can be easily taken out, and further,
By operating the control unit F, the upper and lower holding rollers 97a,
By making only the sheet paper 97b driveable independently of the feeding shaft 23, only the cut sheet paper P can be fed onto the toilet seat body 11.

The seating sensor 84 can be integrated into the automatic sheet paper supplying toilet seat A or can be separated and made into a separate body, depending on usage conditions and usage environment.

Furthermore, in addition to the seating sensor 84, the load at the time of seating may be detected by a load cell or the like to operate the control unit F.

In addition, in FIG. 2, 85 cuts off the power to the rotation motor 30 when the toilet seat body 11 is not detected when the toilet seat body 11 is in a state where it cannot be seated (when the toilet seat body 11 is independent). This is a sensor for stopping the supply of sheet paper P, and detects the toilet seat body 11 only when the toilet seat body 11 is in a seatable state and makes it operable.

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

Hereinafter, the operation of the automatic sheet paper supplying toilet seat A having the above structure will be explained with reference to the flowchart shown in FIG.

First, turn on the power with the power switch S and check whether the power lamp 62 is lit (100).

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

After checking, push button 61 for sheet paper feeding
Press (101).

At this point, if there is a paper jam or there is no sheet paper roll R, press the paper jam lamp 64 on the operation section G.
Or the paper supply lamp 63 lights up (102)
(103).

No paper jams and sheet paper roll R
When there is enough paper jam, or when the paper jam is cleared or the sheet paper roll R is set in the sheet paper roll storage box 70, the control section F operates to drive the rotary motor 30 and to operate the clutch. The mechanism M is driven to select a gear train that communicates with the feed roller 24 and the upper and lower holding rollers 97a and 97b of the presser roller 71.

As a result, the rotation of the rotary motor 30 is transmitted to the feed roller 24 and the upper and lower holding rollers 97a and 97b of the press roller 71 via the gear train. By the way, the feed roller 24 and the press roller 71 rotate in opposite directions and hold the sheet paper P in a pressed state, so that the sheet paper P is stored in the sheet paper roll R in the sheet paper roll storage box 70. It will be unrolled from

That is, as shown in FIG. 5, the sheet paper P is folded upwardly and outwardly by the presser roller 71 to uncurl the sheet paper roll R, and then the sheet paper P is folded between the feed roller 24 and the presser roller 71. and upper and lower holding rollers 97
a and 97b, and then is fed and supplied onto the toilet seat main body 11 through the sheet paper take-out slit 75.

In addition, in the above operation, the upper and lower holding rollers 9
7a and 97b also function as rollers for feeding out the sheet paper P.

In addition, in this feeding operation, when the sheet paper P is fed out a predetermined length onto the toilet seat body 11, the position detection sensor 83 detects the position detection through hole 82 provided in the center of the sheet paper P. , actuates the control unit F to stop the rotation of the rotary motor 30. As a result, the feeding/supplying operation of the sheet paper P by the feeding roller 24 and the pressing roller 71 and the upper and lower holding rollers 97a, 97
The rotational movement of b also stops instantaneously, and the sheet paper P is fed out onto the toilet seat body 11 by an accurate predetermined length (104).

In addition, although the sheet paper P is curled upward at the stage of being unwound from the sheet paper roll R, in this embodiment, the press roller 7
1, the above-mentioned upward curling of the sheet paper P can be reversed, and conversely, downward curling can be given, and then the sheet paper P can be sent out onto the toilet seat main body 11 in a downward state from the paper taking-out slit 75.

Therefore, the sheet paper P curls upward and is sent out only into the functional part casing H,
It is possible to reliably prevent paper jam accidents caused by paper not being fed onto the toilet seat main body 11, and also to prevent sheet paper P fed out onto the top surface of the toilet seat main body 11 from being fed to a predetermined position near the paper ejection slit 75. This can prevent curling.

Further, the detection output of the position detection sensor 83 operates the control unit F to stop the rotation of the rotary motor 30, and at the same time operates the clutch mechanism M to disconnect the rotary motor 30 via the gear train. The cutting blade 28 is reciprocated by communicating with the blade moving shaft 25, and the upper and lower holding rollers 97a, 97 of the sheet paper P are
Instantly cut at a position behind b (105).

Further, the rear end of the sheet paper P is pressed and held by upper and lower pressing rollers 97a and 97b (106).

In this way, the sheet paper P that has been fed out is cut and held immediately after being fed out, so the large number of sheet papers P wound around the sheet paper roll R is
Even if an attempt is made to continuously pull out the sheet paper P further intentionally or as a prank, only one sheet of paper P that has already been fed out can be pulled out, and it is ensured that the sheet paper P is not continuously taken out due to a mischief etc. can be prevented.

Moreover, since the sheet paper P is securely held after cutting the sheet paper P, it is possible to reliably prevent the sheet paper P from falling from the toilet seat 11 due to a breeze, and there is no need to worry about the sheet paper P falling. It is possible to easily add urinals and improve usability.

Thereafter, the user cuts off the central part of the sheet paper P along the perforations 80 leaving only the non-perforated part 81, hangs the part downward, and puts its tip into the standing water in the flush toilet bowl 10.

As described above, in this embodiment, the sheet paper P can be fed to a predetermined length onto the toilet seat main body 11 and cut and held reliably by a one-touch operation.

Furthermore, due to the operation of the control unit F, even if the sheet paper feeding push button 61 is pressed while the same sheet paper supply is completed, the next sheet paper P will not be fed or fed, to prevent tampering and prevent use. Consideration is given to determining whether or not it is possible.

Thereafter, the user sits on the toilet seat body 11 to relieve himself, stands up from the toilet seat body 11 after defecating (107), and pulls out the sheet paper P with a tensile force greater than the pressing force of the holding rollers 97a and 97b, and the cleaning device is driven to clean the inside of the flush toilet bowl 10, and the force of the flush water entrains the cut-off portion of the sheet paper P together with the flush water and filth, which can flow out (109).

In addition, the user can also
Instead of pulling out the sheet paper P by hand against the pressing force of The pressing and clamping force between the upper and lower holding rollers 97a and 97b can be released, and the sheet paper P can be easily taken out.Furthermore, the control unit F can be actuated to feed out only the upper and lower holding rollers 97a and 97b. It may be configured to be able to be driven independently of the section 23 so that only the cut sheet paper P is fed onto the toilet seat body 11 (108).

In addition, in the above operation, the seating sensor 84
The control unit F cannot be operated unless the sensor is sensed for at least 10 consecutive seconds (that is, unless the user is seated for 10 consecutive seconds).

Therefore, it is possible to prevent the release operation of the sheet paper P due to erroneous sensing, such as sensing the sheet paper P in the middle of feeding or sensing an instantaneous movement of the user other than sitting down.

It should be noted that the timing for setting the seating sensor 84 and the time lag for preventing malfunctions can be set according to the environment by the control section F.

In addition, when using a public place such as a theater, after the above series of operations are completed,
It is also possible to operate the control section F to automatically supply the sheet paper P onto the toilet seat main body 11, cut it, and hold the rear end of the sheet paper P for the next user.

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

That is, in this embodiment, the reset mechanism is composed of a reset switch 87 provided on the back surface of the front extending portion 20a of the mounting board 20, and by operating the switch 87, the above-mentioned normal usage procedure is reset. The sheet paper P can be cut at any stage and the sheet paper automatic supply toilet seat A can be returned to its initial state without any trouble.

To explain the safety mechanism in this embodiment, in order to ensure safety of maintenance, the cutting blade 2
8 is adapted to stop operating when a desired sensor (not shown) detects that the cover casing 60 is completely accommodated.

Furthermore, since the sheet paper P is set to be cut inside the functional casing H, not only is the safety of the user ensured, but the sheet paper P is not exposed outside the functional casing H. This prevents water from adhering to the surface.

In this embodiment, the sheet paper P feeding operation is semi-automatic, that is, the sheet paper P
without accurately supplying and positioning it on the toilet seat body 11, slightly taking it out from the sheet paper taking out slit 75 of the functional part casing H,
The sheet paper P can also be fed and positioned onto the toilet seat main body 11 by the user pulling out the sheet paper P by hand.

In this case, the position detection through hole 82 provided in the sheet paper P can be made unnecessary.

Furthermore, the position detection sensor 83 can be made unnecessary by counting the number of revolutions of the rotary motor 30 with a desired counter and activating the control section F based on the counted value for positioning the sheet paper P. can.

In addition, in the case of semi-auto, sheet paper P
The drawer is configured so that it is locked by the control unit F after it has been pulled out to an appropriate length.

In addition, if the sheet paper P is pulled out to an inappropriate length, the control unit F will not lock the sheet paper P, so the control unit F is configured so that the next automatic cutting of the sheet paper P upon detection of the seating sensor does not operate. are doing.

The sheet paper P can be provided with transverse perforations that can be easily cut after each use, so that the sheet paper P can be cut automatically by the weight of the user as soon as he/she sits on the toilet seat main body 11.

In this case, the sheet paper cutting mechanism section D and the sheet paper holding mechanism section I can be omitted, and the toilet seat configuration can be diversified.

By collectively covering electrical components (control unit F, operation unit G, etc.) on one side of the functional unit casing H, water resistance and electrical safety can be improved.

The storage of the sheet paper roll R is completely separated from the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section D, taking into consideration the electrical safety when replacing the sheet paper roll R and the safety of the cutting blade 28. It has a box-shaped structure.

The sheet paper take-out slit 75 located at the upper part of the cover casing 60 is provided with an inclination for returning water to prevent water from adhering to the sheet paper P as much as possible.
