Further, as will be described later, the sheet paper (P) is clamped between the feed roller (31) and the press roller (32), but in this case, both rollers (31)
(32) are engaged by the transmission gears (42) and (43), so as long as the rotary motor (40) is stopped, not only the feed roller (31) but also the presser roller (32)
) can be reliably prevented from rotating, and loosening of the clamping force due to slipping of the pressing roller (32) can be reliably prevented.

Next, the structure of the sheet paper cutting @ structure (b) will be explained.

In this embodiment, the sheet paper cutting mechanism (D) is connected to the gauging body (D) as shown in FIGS. 4 and 5.
a movable plate (50) swingably disposed within the plate insertion space (22a) provided in the front part of the inclined ceiling wall (22) of 16), and a movable plate (50) disposed above the movable plate (50); And the swing arms (34) (35) of the suspension support frame (33)
A rocking plate (5
1).

First, the structure of the movable plate (50) will be explained. As shown in FIGS.

- The tote (50) is formed from a long and wide rectangular flat plate extending in the left-right direction, and has pivots (52) (
53) protrudes, and the same pivots (52) (53) are respectively connected to the left and right side walls (18) (
19).

In addition, (54) and (55) are the guide rollers (
70) is a biasing spring attached to the pivot shafts (52) and (53) in order to keep the disc cam (71) in constant contact with the disc cam (71).

Further, (56) is a sheet paper pressing piece made of an elastic material, which is provided at the rear of the upper surface (50a) of the movable plate (50) and cooperates with the sheet paper pressing piece (64) of the swinging plate (51), which will be described later. Then, the sheet paper (P) is clamped.

Then, when feeding out the sheet paper (P) onto the toilet seat body (11), as shown in Fig. 4, the movable plate (
The upper surface (50a) of 50) is made approximately parallel to the upper surface of the inclined ceiling wall (22), and a sheet paper exit path (8) is provided above it.
can be formed.

In addition, as will be described later, when cutting the sheet paper (P), the movable plate (50) is rotated with the pivots (52) (53).
) to assume the rotational positions shown in FIGS. 7-9. Furthermore, when the toilet seat is not in use, the movable plate (50) can be made to take the rotational position shown in FIG. 10.

Next, the configuration of the swing plate (51) that cooperates with the movable plate (50) to cut the sheet paper (P) will be explained.

As shown in FIG. 4, the swing plate (51) is formed of a thick sheet paper pressing part (60) and a thin sheet paper cutting part (61) when viewed from the side, and has an opening facing downward. It has a U-shaped cross section.

This swing plate (51) has pivots (62) (63) protruding from both ends of the upper part of its sheet paper pressing part (60), and both pivots (82) (63) are attached to the hanging support frame ( 33
) is rotatably supported at the front lower end of the left and right swing arms (34) and (35).

Furthermore, the swinging plate (51) has a sheet paper pressing piece (64) made of an elastic material attached to the lower end of its sheet paper pressing part (60), and the pressing piece (64) and the movable plate (50) are connected to each other. Sheet paper pressing piece (56)
Accordingly, the sheet paper (P) can be clamped without slipping.

In addition, return springs (65) (66) are attached to the pivots (62) (63), respectively, and the springs (65) (66) move the swing plates (5) as shown in FIG. The standby position shown in FIG. 4 is always biased to rotate counterclockwise, and works in cooperation with stoppers (67) and (68) protruding from the inner surfaces of the sheet paper roll mounting walls (23 and 24). That is, the swing plate (51) can be held such that the sheet paper cutting section (61) is in a position retracted from the sheet paper delivery path (8).

Next, the movable plate (50) and the swing plate (51
) The drive mechanism for the sheet paper cutting mechanism (D) may take various forms, but in this embodiment, it is constructed as shown in FIGS. 4 to 6.

That is, the movable plate (50) has a guide roller (70) attached at a lower part thereof and at a position eccentric to the rear from the pivot shafts (52) and (53). The lower part of the guide roller (70) is in rotatable contact with the guide roller (70), and by rotation, the guide roller (70) is in contact with the guide roller (70).
A disc cam (71) that moves the 0) up and down is installed.
The rotating shaft (72) to which the disk cam (71) is fixed has both ends connected to the rectangular mounting plate (17) of the casing body (16).
It is rotatably supported by a pair of bearing stands (73) erected above. Further, the − side extension portion of the rotating shaft (72) passes through the left side wall (18) and extends through the sheet paper roll mounting wall (
23) and the outer wall (23a), and the extension part is operatively connected to a rotation motor (75) via a speed reduction device (74).

With this configuration, when the rotary motor (75) is driven, the rotary shaft (72) rotates, and the disc cam (71) that is integrated with the rotary shaft (72) also rotates about the axis of the rotary shaft (72). It will rotate as. However, the disk cam (7
Since the center of 1) is eccentric from the axis of the rotating shaft (72), the peripheral surface of the disc cam (71) draws a cam locus of an irregularly shaped circle, and the guide roller (
70) moves up and down, and due to this up and down movement, movable play)
(50) can be swung around the pivots (52) and (53), and in conjunction with the swiveling of the movable plate (50), the swiveling plate (51) also swings, allowing the sheet paper to be (P) can be effectively cut in the manner described below.

First, in FIG. 4, the sheet paper (P) is fed by the sheet paper feed [) (8) by the rotation of the feed roller (31) and press roller (32) driven by the sheet paper feed mechanism section (C) described above. through the toilet seat body (11). In addition, at that time, the cutting perforation (90) provided in the sheet paper (P) (third
(see figure) is fed out so that it is positioned substantially directly below the cutting blade (61a) of the sheet paper cutting section (61) of the swing plate (51).

Next, the rotary motor (75) is driven to rotate the disc cam (71).
) is rotated clockwise, the movable plate (50) is rotated counterclockwise about the pivots (52) and (53) via the guide roller (70), and as shown in FIG. The paper pressing piece (56) is connected to the swing plate (
Clamp the sheet paper (P) together with the sheet paper pressing piece (64) of 51). The same clamp part, the feeding roller (31) and the holding roller (32)
) is pressed and bent upward by the rear end of the movable plate (50) to apply tension to the sheet paper (P), which is located between the clamp portion and the clamp portion in contact with the movable plate (50).

In addition, as mentioned above, the feeding roller (31) and the holding roller (32) are engaged by the transmission gears (42) and (43), and the movable plate (50) and the swinging plate (51) are Paper pressing piece (56) (64)
Since the sheet paper (P) is clamped through the clamp, slippage at the clamp portion can be reliably prevented.

Thereafter, when the disk cam (71) is further rotated clockwise, the movable plate (50) further rotates counterclockwise as shown in FIG.
will rotate the swing plate (51) clockwise. Therefore, the cutting blade (61a) provided at the tip of the sheet paper cutting portion (61) of the swing plate (51) further applies tension while pressing the sheet paper (P) downward.

Further, as shown in FIG. 9, if the disc cam (71) is rotated clockwise, the movable plate (50) further rotates counterclockwise, and the swing plate (51) rotates clockwise. By the same rotation, the swing plate (51)
The cutting blade (61a) of the sheet paper cutting unit (61) further presses the sheet paper (P) downward to apply tension, and as a result, the sheet paper (P) is cut from the perforation (90). It turns out. The sheet paper (P) after cutting continues to be clamped by the pressing pieces (56) and (64).

After the user sits down and relieves himself, the toilet seat body (11
), the seating detection means (96), which will be described later, detects the movement of the person leaving the seat, and the detection signal is sent to the control unit (F
), the disc cam (71) further rotates clockwise, and the movable plate (50) rotates clockwise this time, releasing the clamp on the sheet paper (P) and moving it as shown in FIG. By taking the position shown, it is possible to effectively prevent splashed water from flowing into the sheet paper delivery path (8).

In addition, since the sheet paper (P) is cut by applying tension and pressing force to the sheet paper (P), the sheet paper cutting part (61) of the swing plate (51) or its cutting blade is used to cut the sheet paper (P). (61a) need not be formed from a sharp metal or the like, but can also be formed from a rounded ceramic resin having corrosion and abrasion resistance.

Therefore, even during long-term use, frequent replacement of the swing plate (51) due to corrosion or wear can be prevented, and maintenance can be improved.

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

Moreover, if the cutting blade (61a) is formed into a chevron shape as shown in FIG. 5, cutting becomes easier.

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

In FIGS. 4 and 5, (80) and (81) are support rods fitted into the boss portions (37) and (38) of the suspension support frame (33), which is equipped with a spring (82) inside. Sheet paper roll (R) by support rods (80) (81)
Both ends of a hollow roll core (83) with a roll core (83) attached to its outer circumferential surface are removably inserted and constructed.

Further, (84) is a sheet paper roll protective cover disposed on the casing body (16) in a state surrounding the sheet paper roll (R), and its front lower end is located at the sheet paper outlet (85). Hanging support frame (33
) The cover holder installed between the front lower ends of the swing arms (34) and (35) is removably engaged and supported on the stop plate (86), and the rear lower end is connected to the rear wall of the casing body (16). (
21) is engaged with and supported by the upper end of an extended rear wall (87).

Also □, the above sheet paper roll protective cover (84)
As shown in FIGS. 5 and 11, both ends of the sheet paper roll mounting wall (23) are engaged with fitting grooves (88) and (89) recessed along the inner edge of the sheet paper roll mounting wall (23). .

With this configuration, when the sheet paper (P) is unrolled, or when the movable plate (50)
The suspension support frame (3
3) Can prevent the book from swinging.

In addition, in the unlikely event that the rate paper (P) becomes clogged or entangled in the sheet paper feed path (8), etc. and causes trouble, remove the sheet paper roll protection cover (84) as shown in Figure 11. After that, by swinging the hanging support frame (33) forward, the entangled sheet paper (P) can be easily removed.

Next, the sheet paper (P) used in this example will be explained. As shown in FIGS. 4 and 5, the sheet paper (P) forms a part of the sheet paper roll (R). , to be used after cutting.

The reason why the sheet paper (P) is formed from a sheet paper roll (R) is that the sheet paper (P) for multiple people can be stored compactly in the functional section (14) provided at the rear of the toilet seat body (11). This is for storing the toilet seat, and also for automatically and accurately extending it to the top surface of the toilet seat body (11).

In addition, as shown in Fig. 3 and Fig. 12, the sheet paper (P) is provided with linear cutting perforations (90) in the width direction at regular intervals in the longitudinal direction or in the feeding direction. The sheet paper (P) will be cut along the grain (90).

In addition, the sheet paper (P) has perforations for cutting (90
), (9G) is provided with a cutout perforation (91) that matches the inner shape of the toilet seat body (11), and the sheet paper is cut out along the cutout perforation (91). By cutting out (P), the flush toilet (
1G) may be provided.

However, the cut-out perforation (91) is not completely annular, and a non-perforated part (92) is formed between both ends of the rear part, so when the cut-out perforation (91) is cut out, The cut central portion will hang down into the flush toilet bowl (10), and its lower end will be submerged in standing water.

In addition, the sheet paper (P) is not completely perforated, and the non-perforated part (92) and the cutout perforation (91)
) is provided because if it is made with a hole, there will be no waist,
This is because it is almost impossible to bend or form a sheet paper roll (R) when feeding the sheet paper (P) onto the toilet seat body (11). In other words, the sheet paper (P) provided with the perforations for cutting out (91) and the non-perforated portion (92) has sufficient stiffness,
Both automatic feeding and roll processing are easily possible.

In addition, perforations for cutting out sheet paper (P) (9
1) can prevent as much as possible the sheet paper (P) from getting caught up in the feeding roller (31) and the pressing roller (32) during feeding and causing a paper jam.

In addition, perforations for cutting out sheet paper (P) (9
In 1), it is possible to have perforations throughout the toilet seat body (11) in a shape that matches the inside shape, or it is also possible to have perforations here and there and cuts elsewhere. .

Furthermore, as shown in FIGS. 3 and 12, the sheet paper (P) is arranged at constant intervals in the longitudinal direction between the non-perforated part (92) and the tip of the cutout perforation (91). A position detection through hole (93) is provided between the holes, and a light emitting element and a light receiving element are provided at the front of the inclined ceiling wall (22) of the gauging body (16) corresponding to the through hole (93). A position detection sensor (94) is provided which also functions as a paper detection means.

The position detection sensor (94) is located in the sheet paper delivery path (8) up to the top of the toilet seat body (11) when the sheet paper (P) is fed out a predetermined length from the sheet paper roll (R). , sheet paper (
P) and the through hole (93), stop the operation of the sheet paper feeding mechanism (C), and accurately supply and position the sheet paper (P) on the toilet seat body (11). Can be done.

Moreover, the same sensor (94) is located in the functional part casing (15).
Sheet paper (P
), the control section (F) stops the rotation motor (40) and controls the sheet paper feeding mechanism section (C) so as not to operate.

Therefore, double feeding of the sheet paper (P) due to mistake or mischief of the sheet paper CP) can be prevented, so problems such as paper jams do not occur within the functional part casing (15), and the sheet paper Sending path (8
), unless you remove the sheet paper (P) that is still being fed out over the toilet seat body (11), the next sheet of paper (P) will not be fed even if you press the sheet paper feeding push button (103). It is now impossible to release it.

In addition, instead of such a through hole (93), sheet paper (
A desired colored mark may be applied to the sheet paper (P), and the attachment position of the through hole (93) etc. can be not only at the center of the sheet paper (P) but also at any arbitrary location.

In addition, the above-mentioned supply and positioning of sheet paper (P) are as follows:
Counting the number of rotations of the rotary motor (40) with a desired counter without using the position detection sensor (94),
This can also be done by operating the control section (F) based on the counted value.

In this embodiment, the paper detection means is replaced by a position detection sensor (
94), but the sheet paper feed path (8
It goes without saying that the object of the present invention can be achieved even if a paper detection sensor or the like is separately provided as a paper detection means at any position where the sheet paper (P) of ) can be detected.

In addition, in Fig. 1, (96) is the casing body (1
6) is a seating detection means consisting of a reflective infrared sensor etc. provided on the inner surface of the - side extension part (25), and after the user sits on the toilet seat main body (11), it detects the presence of the user for a certain period of time (for example, 5 seconds).
When the user leaves the toilet seat body (11) after a while, a detection signal is generated, the control unit (F) is activated, the rotation motor (75) is driven, and the sheet paper (P) is clamped. At the same time, the sewage sheet paper delivery path (
8) to block the movable plate (50) from entering the
and the swing plate (51) from the position shown in FIG.
The position can be moved to the posture shown in Figure 0.

Note that the seating detection means (96) can be integrated into the automatic sheet paper supply toilet seat (^) or can be separated and made into a separate body, depending on the usage conditions and usage environment.

Furthermore, the seating detection means (96) may use microswitches, limit switches, etc. in addition to infrared sensors, etc., or detect the load at the time of seating with a load cell, etc., and control the control unit (',
It is also possible to activate F).

In addition, in Fig. 1, (se) indicates that the control unit is disconnected 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 independent). (F) is an abnormal feeding prevention sensor that cuts off the power to the rotation motor (40) and stops the supply of sheet paper (P), and the toilet seat body (11) is in a state where it can be seated. The toilet seat main body (11) is detected only at certain times and made operable.

In addition, a microswitch, a limit switch, etc. can also be used for the abnormal delivery prevention sensor (97) instead of a normal sensor.

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 (D), and various sensors and detection means will be explained.

As shown in FIG. 5, the control unit mounting plate (100
) is installed upright, and on the control unit mounting plate (100),
A control panel (101) is attached to control the operation of the rotation motor (4G) (75) described above, and forms a control section (F). Note that the control panel (101) also has a transformer (102) installed therein.

Next, the operation part (G) will be explained. As is most obvious from FIG. 1 and FIG. Push button for feeding sheet paper (103).

A power lamp (104) consisting of a light emitting diode, etc., a paper replenishment lamp (105) with a warning function in the event of an abnormality such as paper replenishment or paper jam, and a paper trouble lamp (1).
06) etc.

Note that a buzzer or the like may be installed instead of the paper replenishment lamp (105) or the like.

Also, in Fig. 13, sheet venever automatic supply service M (^)
An example of the circuit configuration of the control section (F) which controls the operation of the controller (F) is shown.

As shown in FIG. 13, the control unit (F) includes a microprocessor (14PU) and an input/output interface (110
) (111) and base sheet paper feeding/
It consists of a memory (M) that stores a cutting order program.

The input interface (110) connects a push button for sheet paper feeding (103), a position detection sensor (94), a seating detection means (96), an abnormal feeding prevention sensor (97), etc., and a microprocessor (HPU). The output interface (111) is interposed between the microprocessor (MPU) and the sheet vapor feeding mechanism section (C) = sheet paper cutting mechanism section (D), etc.

A lock circuit (Q) is incorporated in the microprocessor (MPU), and after the sheet paper (P) is fed out for a predetermined length, the lock circuit (Q) detects the seating detection means (96). As long as the output from is being sent to the control unit ([), the sheet paper feeding push button (
103) is configured so that the sheet paper (P) is not fed out even when pressed.

Therefore, even if the user or a child accidentally presses the sheet paper feeding push button (103) after sitting, the sheet paper (P) will not be fed out.

Further, to explain other configurations of the illustrated example of the palanquin, in FIG. Then, □Rotation motor (4G) (
75) can be cooled.

Hereinafter, the sheet paper automatic supply service M having the above configuration (
Regarding the operation of ^), Figure 14 (A) and Figure 14 (B)
) will be explained with reference to the flowchart shown in FIG.

In the de-energized state, the movable plate (50) in the gauging body (16) closes the sheet paper outlet (85) as shown in FIG. (85) into the sheet paper delivery path (8).

In this state, when using the flush toilet (10) now, as shown in Fig. 5, when the power switch (S) provided on the back of the casing body (16) is turned on (ISO), the power lamp (104) ) lights up (151).

Next, when the sheet paper feeding push button (103) is pressed (152), the control section (F) generates a drive signal based on the sheet paper feeding/cutting order program read from the memory (N), and the same The rotation motor (75) of the sheet paper cutting mechanism section (D) and the rotation motor (40) of the sheet vapor feeding mechanism section (C) are activated by the drive signal.
operate in sequence.

The disc cam (7) is driven by the rotary motor (75).
The clockwise rotation in step 1) causes the movable plate (50) to rotate counterclockwise, changing from the posture shown in FIG. 10 to the posture shown in FIG. 4. That is, the movable plate (5
0), a sheet paper delivery path (8) communicating with the sheet paper delivery port (85) is formed on the paper (
157).

Thereafter, the rotation motor (40) is driven to unwind the sheet paper (P) from the sheet paper roll (R) (158).

However, when the sheet paper roll protection cover (84) is not attached to the casing body (16), the cover safety switch (not shown) is in the OFF state, so the sheet paper feeding push button (103) is pressed. Even if it is pressed (1152), the drive signal is not sent from the control unit (n) to the rotation motor (40) by the control of control ## (F) (153), ensuring safety of operation. Can be done.

Also, if the user is sitting on the toilet seat body (11) with the sheet paper (P) not being fed out, the sheet paper (P) cannot be fed out onto the toilet seat body (11). Since this is not preferable, the seating detection means (96) is activated and the control section (F) transmits the drive signal to the rotation motor (4).
0) (154).

In addition, since it is not desirable for the sheet paper (P) to be fed out onto the toilet seat body (11) when the toilet seat body (11) is standing, the abnormal feeding prevention sensor (97) is connected to the toilet seat body (11).
11) detects that there is a standing state, and the control unit (F)
However, the drive signal is not sent to the rotation motor (40) (155).

Furthermore, the position detection sensor (94) that also serves as paper detection located inside the casing body (16) detects the presence of sheet paper (P) in the sheet paper delivery path (8) within the gauging function section (15). Even if it is detected, the sheet paper (P) will not be fed out until the functional part casing (15)
Since the sheet paper (P) will be entwined inside,
Based on the detection output, the control unit (156) prevents the drive signal from being sent to the rotation motor (40).
.

If there is no abnormal condition mentioned above, as mentioned above,
A drive signal is sent from the control unit (F) to the rotary motor (40) to drive the rotary motor (40) (158), and the sheet paper (P) is fed out from the sheet paper roll (R).

Also, when the rotation motor (40) starts driving, the timer circuit (■) (Fig. 13) is activated (159), and the sheet paper (P) is fed out onto the toilet seat body (11), and then, The position detection sensor (94) detects the sheet paper (P) normally, that is, within the set time (tl), and also detects the through hole (P) provided in the sheet paper (P) within the set feeding time (t2). 93) is detected, (15
9cY), the rotating motor (40) stops (16G) with the set length of sheet paper (P) being fed out onto the toilet seat body (11).

Note that at this point, the cutting perforation (90) located at the rear end of the sheet paper (P) is
) is located approximately directly below the sheet paper cutting blade (61a).

However, if there is an abnormality in the detection of the position detection sensor (94), that is, the position detection sensor (94) detects the through hole (93) of the sheet paper (P) within the set feeding time (tl).
If not detected (1598N), the automatic sheet paper feeding motor (40) is turned off and the paper trouble lamp (106) is turned on (161).

Also, even if sheet paper (P) is detected within the set time (tl), the next timer set time (t2) (rotation motor
If the position detection sensor (94) detects the through hole (93) earlier than (counted from the start of driving of the motor (40)) (
159bY) similarly turns off the rotation motor (40) and turns on the paper supply lamp (105) (162
).

Furthermore, if the through hole (93) is not detected within the timer setting time (t2) (151CN), the rotation motor (40)
At the same time, the paper trouble lamp (IOE) is turned on (163).

Note that the above-mentioned position detection sensor (94) detects the passage of the sheet paper (P) in the sheet paper delivery path (8), and if there is no detection output, it is determined that there is no paper or a paper jam and the rotation is performed. Immediately stop the motor (40),
A paper trouble lamp (108) can also be turned on (163).

Thereafter, the user can take necessary measures such as replenishing paper and checking.

Then, the rotation motor (75) is restarted by the drive signal from the control unit (P), and as shown in FIGS. 7 and 8,
Press the sheet paper (P) with the sheet paper pressing piece (56
) (64) and the feeding roller (3
1) and the presser roller (32), and then, when the rotary motor (75) continues to be driven by continuous drive signals from the control unit (F), the sheet paper (P) located between both clamp parts is clamped. ) will be subjected to tension in the feeding direction (164).

Furthermore, the rotation motor (
75) is driven, the sheet paper cutting blade (61a) of the sheet paper cutting section (61) of the swing plate (51) cuts the sheet paper (P) at the cutting perforation (90 ), and the sheet paper (P) is
It will definitely break or be severed (165)
.

Therefore, the rear end of the cut sheet paper (P) is securely clamped by the sheet paper pressing pieces (56) and (64) (165).Then, the user places the sheet paper (P) on the toilet seat body (11). When the person is seated (169), the seating detection means (96) detects that the person is seated (170);
Based on the detection output, the control unit (F) controls the rotation motor (40
) (171)
.

Therefore, even if the user presses the sheet paper feeding push button (103) by mistake or mischievously while seated, the sheet paper (P) will not be fed out, so the sheet in the gauging body (16) will not be fed out. Accidents such as entanglement of paper (P) can be reliably prevented.

Then, when the user leaves the toilet seat body (11) after using the toilet (172), the seating detection means (96) is turned off (173), and based on the OFF signal, the control section (') rotates. Send the drive signal to the motor (75) again and rotate the rotary motor (75).
(50) and the swing plate (51) will assume the state shown in FIG. 'That is,
While the clamp on the sheet paper (P) is released,
The movable plate (50) is a sheet paper outlet (85)
The casing body (
16) can be taken within (174) (175).

Thereafter, the cleaning device is driven to clean the inside of the flush toilet bowl (10), and the force of the flushing water entrains the cut-off portion of the sheet paper (P) together with the flushing water and dirt and allows it to flow out.

In the above step, after the sheet paper (P) is cut and held (165) by the cooperation of the movable plate (50) and the swing plate (51), and before the sheet paper (P) is seated (169), if someone Forced sheet paper (P)
(166) or when the toilet seat body (1
1) If the sheet paper (P) fed out above is wet and the sheet paper feeding push button (103) is kept pressed for a predetermined period of time (approximately 5 seconds) to remove it (167), Further, if the user does not sit on the toilet seat main body (11) within a predetermined period of time (168) for some reason, the seat paper is removed by each reset means (not shown) independently of the seat detection means (96). In order to dispose of (P) as unused, the control unit (F) sends a drive signal to the rotation motor (75), and the first
0, release the clamp on the sheet paper (P), and open the sheet paper outlet (85).
) can be closed (174) (175).

With the configuration and operation described above, this embodiment has the following features:
The following effects will be achieved.

That is, the control unit (F) detects that the position detection sensor (94), which also functions as paper detection means, detects that the sheet paper (P) is in the sheet paper delivery path (8) in the functional unit casing (15). As long as this is detected, the sheet vapor dispensing mechanism section (C) is disabled from dispensing the sheet paper (P), thereby preventing double dispensing of the sheet paper (P) due to mistake or mischief. This makes it possible to reliably prevent troubles such as entanglement of sheet paper (P) and paper jams within the functional unit casing (15).
