Some of them are described in the official gazette.

Such a sheet paper roll is configured to feed the sheet paper onto the toilet seat by a desired sheet paper supply device.

That is, the feeding roller and the pressing roller provided in the sheet paper feeding device are made to cooperate with each other to press and nip the pull-out end of the sheet paper, and the sheet paper is fed and fed from the sheet paper roll onto the toilet seat.

(C) Problems to be solved by the invention However, in the case of the above-mentioned toilet seat sheet paper roll, since the pull-out end of the sheet paper is pushed and nipped by the feeding roller and the pressing roller, it is fed out, If the sheet paper is not fed out at the same speed and uniform pressing force over the entire width, the sheet paper is kinked. Therefore, there has been a problem that it is necessary to surely perform the feeding adjustment by the feeding roller and the pressing roller in order to prevent the occurrence of the twist.

In addition, there are problems that the feeding roller idles when the sheet paper is fed, and that slippage occurs and the sheet paper cannot be fed reliably.

(D) Means for Solving the Problems In the present invention, therefore, an opening forming portion is provided at a substantially central portion of a long sheet paper, and a large number of sheet papers are drawn out along the longitudinal direction of the sheet paper. The present invention provides a sheet for toilet seat, which is provided with the locking hole.

By providing an engaging protrusion or the like that engages with the locking hole in the feeding roller or the like of the sheet paper feeding device for feeding the sheet paper, the sheet paper is surely prevented from being kinked or the like. It can be paid out.

(F) Effect According to the present invention, since the sheet paper feeding locking hole provided at one longitudinal end of the sheet paper can be used for reliable feeding, it is possible to feed the sheet paper conventionally. This has the effect of eliminating the trouble of adjusting the feeding by the feeding roller and the pressing roller of the apparatus.

Moreover, there is an effect that the sheet paper can be reliably fed out without providing means for preventing idling and slippage of the feeding roller when the sheet paper is fed out.

Furthermore, since the sheet paper can be reliably fed out, there is an effect that it is possible to prevent the sheet paper from jamming.

Next, when the rotary motor (75) is driven to rotate the disc cam (71) clockwise, the movable plate (50) is centered on the pivots (52) (53) via the guide roller (70).
It rotates counterclockwise and, as shown in FIG. 7, the sheet paper pressing piece (56) clamps the sheet paper (P) together with the sheet paper pressing piece (64) of the swing plate (51). Then, a portion of the sheet paper (P) located between the concentric clamp portion and the feeding belt (31) is pressed and bent upward by the rear end of the movable plate (50) to apply tension to the sheet paper (P). .

As described above, the sheet paper feeding drive shaft (30) wound around the feeding belt (31) and the sheet paper feeding driven shaft (30 ') are engaged by the transmission gears (42) (43), and Movable plate (50) and swing plate (5
With 1), the sheet paper (P) is clamped via the sheet paper pressing pieces (56) (64), so slippage at the clamped portion can be reliably prevented.

After that, when the disc cam (71) is further rotated clockwise, the movable plate (50) further rotates counterclockwise as shown in FIG. 8, while the movable plate (50) moves to the swing plate. (51) will be rotated clockwise. Therefore, the sheet paper cutting portion (6) of the swing plate (51) is
The cutting blade (61a) provided at the tip of 1) further applies tension while pressing the sheet paper (P) downward.

Further, as shown in FIG. 9, when the disc cam (71) is rotated clockwise, the movable plate (50) further rotates counterclockwise and the swing plate (51) rotates clockwise. Then, by the same rotation, the cutting blade (61a) of the sheet paper cutting part (61) of the swing plate (51) further presses the sheet paper (P) downward to apply tension, and as a result, the sheet paper (P ) Will be cut from the perforation (90).

Then, the sheet paper (P) after cutting is pressed by the pressing piece (5
6) Continue to be clamped by (64).

Then, after the user sits down and wears the legs, the toilet seat body (11)
When it is separated from, the seating detection means (96) described later detects the separation movement, and when the detection signal is sent to the control section (F), the disc cam (71) further rotates in the clockwise direction, The movable plate (50) now rotates clockwise,
Release the clamp of the sheet paper (P) and
By taking the position shown in FIG. 10, it is possible to effectively prevent the splashed water from flowing into the sheet paper delivery path (8).

Since the sheet paper (P) is cut by applying tension and pressing force to the sheet paper (P), the sheet paper cutting portion (61) of the swing plate (51) or its cutting blade. (61a) does not need to be formed of a sharp metal or the like, and may be formed of rounded ceramics or a synthetic resin having corrosion resistance and abrasion resistance.

Therefore, even when used for a long period of time, it is possible to prevent frequent replacement of the rocking plate (51) due to corrosion or wear,
Maintenance can be improved.

Similarly, in consideration of the corrosion resistance and wear resistance of the movable plate (50), the movable plate (50) can be formed of ceramics or the like.

Further, if the cutting blade (61a) is formed in a mountain shape as shown in FIG. 6, the cutting becomes easy.

Next, the configuration of the sheet paper roll storage section (E) arranged on the casing body (16) including the sheet paper feeding mechanism section (C) and the sheet paper cutting mechanism section (D) will be described.

In FIGS. 4 and 6, (80) and (81) are boss portions (37) of a suspension frame (33) having a spring (82) inside.
A support rod fitted in the (38), the support rod (80) (81)
Thus, both ends of the hollow roll core (83) having the toilet seat sheet paper roll (R) mounted on the outer peripheral surface are detachably inserted and installed.

Further, (84) is the sheet paper roll for the above-mentioned toilet seat (R)
Is a protective cover for the sheet paper roll disposed on the casing body (16) in a state of being surrounded by the suspension main frame (33) at the lower end of the front portion of the sheet paper feed port (85).
The swing arm (34) (35) is detachably engaged and supported on a cover receiving plate (86) installed between the lower ends of the front and lower ends of the rear end of the rear wall (21) of the casing body (16). It is engaged with and supported by the upper end of an extended rear wall (87) extending to the upper part of the.

Further, as shown in FIG. 6 and FIG. 11, both side ends of the sheet paper roll protective cover (84) are provided with fitting grooves (which are recessed along the inner edge of the sheet paper roll mounting wall (23)). 88) (89) engaged.

With such a configuration, when the sheet paper (P) is unwound, or the movable plate (50) is moved to the swing plate (51).
It is possible to prevent the suspension frame (33) from swinging due to vibration or the like generated when the suspension frame (33) contacts.

If a trouble occurs due to the sheet paper (P) being jammed or entangled in the sheet paper delivery path (8), etc., the sheet paper roll protective cover (84) is removed as shown in FIG. After that, by swinging the suspension frame (33) forward, the entangled sheet paper (P) can be easily taken out.

Next, the sheet paper (P) used in this example will be described. As shown in FIGS. 4 and 6, the sheet paper (P) forms a part of the toilet seat sheet paper roll (R). And is used by cutting.

The sheet paper (P) is formed from the toilet seat sheet paper roll (R) because the seat paper (P) for a large number of people is compactly provided at the rear of the toilet seat body (11).

An opening communicating with the inside of the flush toilet bowl (10) can be provided by cutting out the paper (P).

However, the cutout perforation is not a complete ring, and since there are no perforated parts (92) between both ends of the cutout, when the cutout perforation is cut out, the cut out central part is It will drip into the flush toilet bowl (10), and its lower end will collect and be submerged in water.

Further, the sheet paper (P) is not completely perforated, but the perforation-free portion (92) and the perforation for cutout are provided. This is because it is almost impossible to bend or form the sheet paper roll (R) for the toilet seat when the sheet is supplied onto the toilet seat body (11). That is, the sheet paper (P) provided with the perforations for cutout and the non-perforated portion (92) has a sufficient stiffness, and both automatic supply and roll processing can be easily performed.

Moreover, while the sensor (94) detects the presence of the sheet paper (P) in the sheet paper delivery path (8) in the functional unit casing (15), the control unit (F) causes the rotation motor ( 40) is stopped and the sheet paper feeding mechanism (C) is controlled so as not to operate.

Therefore, double feeding of the sheet paper (P) due to error or mischief of the sheet paper (P) can be prevented, and troubles such as paper clogging in the functional unit casing (15) do not occur. Paper delivery path (8)
From the above, the next sheet of paper (P) can be fed out even if the sheet paper feeding push button (103) is pressed unless the sheet of paper (P) that has been fed out over the toilet seat body (11) is removed. There is no such thing.

Instead of the through hole (93), a desired colored mark may be provided on the sheet paper (P), and the mounting position of the through hole (93) or the like is only in the central portion of the sheet paper (P). Instead, it can be an arbitrary place.

In addition, the above-mentioned supply and positioning of the sheet paper (P) is
It is also possible to count the number of rotations of the rotation motor (40) by a desired counter without using the position detection sensor (94) and operate the control unit (F) based on the count value.

In addition, as shown in FIGS. 3 and 12, locking holes (32) for feeding, which is the gist of the present invention, are provided at regular intervals in the longitudinal direction at the left and right ends of the sheet paper (P). Many are opened and drilled.

Then, in the locking hole (32), the feeding locking protrusion (31a) of the feeding belt (31) is inserted and locked so that the sheet paper (P) can be reliably fed. , When the sheet paper (P) is cut (broken) by applying tension, the same locking paper (P) is reliably locked by the locking projections (31a) to prevent the sliding of the paper (P). , So that cutting (breaking) can be facilitated.

Further, even when the user is seated on the toilet seat body (11) without the sheet paper (P) being drawn out, the sheet paper (P) is not drawn out into the toilet seat main body (11). Since it is not preferable, the seating detecting means (96) is operated so that the control section (F) does not send a drive signal to the rotation motor (40) (154).

Further, since it is not preferable to feed the sheet paper (P) to the toilet seat body (11) when the toilet seat body (11) is standing, the toilet seat body (11) is in an upright state in the abnormal feeding prevention sensor (97). The control unit (F) prevents the drive signal from being sent to the rotary motor (40) (15).
Five).

Further, the position detecting sensor (94) arranged in the casing body (16) for detecting paper also detects that the sheet paper (P) is present in the sheet paper delivery path (8) in the functional unit casing (15). Even when it is detected, the feeding of the sheet paper (P) causes the sheet paper (P) to be entangled in the functional unit casing (15). Therefore, the control unit (F) rotates the drive signal by the detection output. Dynamic motor (4
I try not to send it to (0) (156).

And if there is no abnormal state, as described above,
A drive signal is sent from the control unit (F) to the rotation motor (40), drives the rotation motor (40) (158), and the sheet paper (P) is fed from the sheet paper roll (R). .

Also, the timer circuit (T) (Fig. 13) is activated (159) when the rotation motor (40) starts to be driven. Then, the sheet paper (P) is fed onto the toilet seat body (11), and then the position detection sensor (94) normally and immediately detects the sheet paper (P) within the set time (t1). At the same time, when the through hole (93) provided in the sheet paper (P) is detected within the set delivery time (t2) (159cY), the set length sheet paper (P) is delivered onto the toilet seat body (11). The rotation motor (40) stops (160).

At this point, the cutting perforation (90) located at the rear end of the sheet paper (P) is located substantially directly below the sheet paper cutting blade (61a) of the swing plate (51).

However, when there is an abnormality in the detection of the position detecting sensor (94), that is, the position detecting sensor (94) does not detect the through hole (93) of the sheet paper (P) within the set feeding time (t1). In the case (159aN), turn off the rotation motor (40) for feeding sheet paper and turn off the paper trouble lamp (10
Turn on 6) (161).

Even if the sheet paper (P) is detected within the set time (t1), the next timer set time (t2) (rotation motor (4
(Counting from the start of driving (0)) When the position detection sensor (94) detects the through hole (93) (159bY)
Turns off the rotation motor (40) and turns on the paper supply lamp (105) (162).

Further, when the through hole (93) is not detected within the timer setting time (t2) (159cN), the rotation motor (40) is turned off and the paper trouble lamp (106) is turned on (16).
3).

The position detecting sensor (94) is caused to detect the passage of the sheet paper (P) in the sheet paper feeding path (8), and if there is no detection output, it is determined that there is no paper or a paper jam, and rotation is performed. The motor (40) can be stopped immediately and the paper trouble lamp (106) can be turned on (163).

Then, after that, the user can take necessary measures such as paper replenishment and inspection.

Then, the rotation motor (75) is restarted by the drive signal from the control unit (F), and as shown in FIGS. 7 and 8, the sheet paper (P) is moved to the sheet paper pressing piece (56).
(64) and also between the feeding roller (31) and the pressing roller (32), and then the rotation motor (7) by the continuous drive signal from the control section (F).
When (5) continues driving, tension in the feeding direction is applied to the portion of the sheet paper (P) located between both clamp portions (164).

Further, when the rotation motor (75) is driven by the drive signal from the control section (F), the sheet paper cutting blade (61a) of the sheet paper cutting section (61) of the swing plate (51) is driven as shown in FIG. Presses the sheet paper (P) along the perforations (90) for cutting, and the pressing force and the tension in the feeding direction reliably break or cut the sheet paper (P) ( 165).

Then, the rear end of the cut sheet paper (P) is securely clamped by the sheet paper pressing pieces (56) (64) (165) After that, the user sits on the toilet seat body (11). Then (16
9), it is detected that the seating detection means (96) is seated (17
0) and the detection output causes the control unit (F) to rotate the rotation motor (4) as long as the seating detection means (96) detects the sheet paper feeding push button (103).
Control is performed so that no drive signal is sent to (0) (171).

Therefore, even if the user accidentally or mischievously presses the sheet paper feeding push button (103) in the seated state, the sheet paper (P) is not fed out, so that the sheet paper inside the functional unit casing (15) is Accidents such as entanglement of (P) can be reliably prevented.

After the toilet, when the user leaves the toilet seat body (11) (172), the seating detection means (96) is turned off (173).
Based on the FF signal, the control unit (F) sends a drive signal to the rotation motor (75) again to rotate the rotation motor (75).
As a result, the movable plate (50) and the swing plate (51) are brought into the state shown in FIG.

That is, the clamp of the sheet paper (P) is released, while the movable plate (50) is moved to the sheet paper delivery port (8
It is possible to take a posture (174) (175) in the casing body (16) so as to surely prevent the invasion of dirty water through the sheet paper delivery path (8) through the (5).

After that, the washing device is driven to wash the inside of the flush toilet (10), and depending on the posture of the washing water, the separated portion of the sheet paper (P) can be caught and discharged together with the washing water and dirt.

In the above step, after the seat paper (P) is cut and held (165) by the cooperation of the movable plate (50) and the swing plate (51), the seat (1)
69) If someone forcibly pulls out the sheet paper (P) before (166), or the sheet paper (P) fed out on the toilet seat body (11) is wet, to eliminate it Push button for feeding sheet paper (103)
For a predetermined time (if pressed for about 5 seconds (167),
Further, when the user does not sit on the toilet seat body (11) within a predetermined time for some reason (168), the resetting means (not shown) causes the sheet paper (P) to be irrelevant to the seating detecting means (96). ), The control unit (F) sends a drive signal to the rotary motor (75), and the movable plate (50) and the swing plate (51) are set to the state shown in FIG. Then, the clamp of the sheet paper (P) can be released and the sheet paper delivery port (85) can be closed (174) (175).

With the configuration and operation described above, the present embodiment is
The following effects are produced.

According to the present embodiment, since the locking holes (32) for feeding the sheet paper, which are provided at both longitudinal end portions of the sheet paper (P), can be used for reliable feeding, the sheet can be fed reliably as in the conventional case. This has the effect of eliminating the trouble of adjusting the feeding by the feeding roller and the pressing roller of the paper feeding device.

Moreover, the sheet paper (P) can be reliably delivered without providing a means for preventing idling and slippage of the delivery roller when the sheet paper is delivered, and the sheet paper (P) is cut by applying tension ( The sheet paper (P) is securely locked by the locking projections (31a) when the sheet paper (P) is broken.
This has the effect of preventing slippage and facilitating cutting (breaking).

Furthermore, since the sheet paper (P) can be reliably fed out, the sheet paper (P) can be prevented from being jammed.
