  The stopper 54 is also used for positioning the top of the replaced roll paper R when the roll paper R is replaced. When replacing the roll paper R, the clerk pulls out the leading end of the roll paper R and passes it through the paper feed / conveying roller 53, and sets it against the abutting portion 54b of the stopper 54 in the closed state (see FIG. 5). . As a result, when replacing the roll paper R, the clerk only has to abut the front end of the roll paper R against the stopper 54, so that the position of the front end of the roll paper R is not shifted, and the roll paper R is stably set. Can be done.

  Further, as shown in FIG. 7, the stopper 54 fixes a post 56 as a shaft body to the bent portion, and this post 56 is a process in which the roll paper storage unit 32 is attached to the roll paper transport unit 33. Then, it collides with an open / close block 31b formed in the roll paper transport unit 33. The post 56 is pushed down by the pressing force received from the opening / closing block 31b in the process in which the roll paper storage unit 32 is mounted on the roll paper transport unit 33, and the stopper 54 rotates in the α4 direction in conjunction with the post 56. As a result, the abutting portion 54b opens the transport path (open state), and the roll paper R can be transported to the roll paper transport section 33.

Returning to FIGS. 5 and 6, the configuration of the set detection sensor 57 will be described. The set detection sensor 57 is a sensor for detecting whether or not the roll paper R can be set on the stopper 54, and is in front of the abutting portion 54b of the stopper 54 in the closed state, and in the width direction of the conveyance path. Two pieces are arranged side by side at spaced positions (on both sides of the conveyance path).
The set detection sensor 57 outputs an ON signal to the control unit 40 when the roll paper R completely hits the stopper 54 and the roll paper R can be detected. On the other hand, when the roll paper R cannot be detected, such as when the roll paper R is set obliquely or when the roll paper R is not completely in contact with the stopper 54, the set detection sensor 57 sends an ON signal to the control unit 40. Do not output.

(Roll paper transport unit)
Returning to FIG. 2, the roll paper transport unit 33 will be described. As described above, the conveyance path is formed inside the casing 31. In the present embodiment, the section from the exit of the roll paper storage unit 32 to the roll paper printing unit 34 is included in the conveyance path formed inside the casing 31.

A suction port 31 a for sucking the roll paper R is formed on the side surface of the housing 31 facing the discharge port 51 b formed in the roll paper storage unit 32.

The first transport roller 71 and the second transport roller 72 are disposed so that the two rollers face each other across the transport path. As shown in FIG. 4, the second transport roller 72 is a motor 74 (see FIG. 4), the first conveying roller 71 rotates simultaneously using the driving force transmitted through the driving belt 70.
Hereinafter, among the first transport rollers 71, the upper rollers may be referred to as “first transport rollers 71a” and the lower rollers may be referred to as “first transport rollers 71b”. Of the second transport rollers 72, the upper roller may be referred to as "second transport roller 72a" and the lower roller may be referred to as "second transport roller 72b".

  The foreign matter prevention shutter 73 as an open / close shutter operates in conjunction with the first transport roller 71 and the second transport roller 72. Hereinafter, with reference to FIG. 8, an interlocking mechanism between the first conveyance roller 71 and the second conveyance roller 72 and the foreign matter prevention shutter 73 will be described.

  The first transport roller 71b and the second transport roller 72b installed in the lower part are installed so as to be movable in the vertical direction (α7, α8 direction in FIG. 8) and in the front-rear direction (α5, α6 direction in FIG. 8). It is connected to a solenoid 78 via slidable link posts 75 and 76 and a link bar 77. The solenoid 78 includes a magnet (or iron plate) (not shown), slides the link bar 77 in the forward direction (α5 direction in FIG. 8) by the magnet attracting operation, and moves the link bar 77 in the rear direction by opening the magnet.

When the link bar 77 slides forward (α5 direction in FIG. 8) due to the suction operation of the solenoid 78, the first transport roller 71b and the second transport roller 72b move upward (α7 direction in FIG. 8). (UP operation), and stops at a contact position where the UP operation causes contact with the first transport roller 71a and the second transport roller 72a. This contact position is a conveyance position where the roll paper R as continuous paper can be nipped and conveyed.
When the link bar 77 slides backward (direction α6 in FIG. 8) due to the opening operation of the solenoid 78, the first conveyance roller 71b and the second conveyance roller 72b move downward (α8 in FIG. 8). Direction) (DOWN operation), and stops at a separation position separated from the first conveyance roller 71a and the second conveyance roller 72a installed at the upper part by the DOWN operation. This separation position is a retreat position where the roll paper R as continuous paper cannot be conveyed.

  The first conveyance roller 71b and the second conveyance roller 72b installed in the lower part are in contact with each other when the roll paper storage unit 32 is mounted on the roll paper conveyance unit 33 and the motor 74 (see FIG. 4). ) Is used to transport the roll paper R to the roll paper printing unit 34 (see FIG. 2) inside the ticket issuing unit 7.

  On the other hand, the first conveyance roller 71b and the second conveyance roller 72b are in the separated positions when the roll paper storage unit 32 is detached from the roll paper conveyance unit 33 or in the automatic ticket machine 1 (see FIG. 1). When the roll paper R is not transported, such as when the power is turned off, or when the roll paper R is transported while being tilted and set, the tilt of the roll paper R is corrected. To correct the inclination of the roll paper R, specifically, from the state where the first conveyance roller 71b and the second conveyance roller 72b installed in the lower part are in the contact position, the DOWN operation is once performed to the separation position, and then again. This is done by performing an UP operation to bring it into the contact position. Hereinafter, this operation is referred to as “conveying roller biting operation”. It should be noted that the conveying roller biting operation is performed in a state where the rotation of the first conveying roller 71 and the second conveying roller 72 is stopped.

  Subsequently, the foreign matter prevention shutter 73 opens and closes the transport path in conjunction with the UP / DOWN operation of the transport rollers 71b and 72b. Specifically, the foreign matter prevention shutter 73 has a shutter support portion 73a that is pivotally supported by the housing 31 and an abutting portion 73b as a closing member that opens and closes the conveyance path according to the rotation state. The plate is bent in a U-shape (U-shape), and is disposed at the center in the width direction of the conveyance path (see FIG. 9). The foreign matter prevention shutter 73 is connected to a link post 79 connected to a link bar 77 that slides in the front-rear direction (α5 and α6 directions in FIG. 8) by the suction / release operation of the solenoid 78.

When the link bar 77 slides forward (in the α5 direction in FIG. 8) due to the suction operation of the solenoid 78, the foreign matter prevention shutter 73 rotates counterclockwise (in the α9 direction in FIG. 8), and the butting portion 73b opens the conveyance path (open state). As a result, the roll paper R can be transported.
Further, when the link bar 77 slides backward (direction α6 in FIG. 8) due to the opening operation of the solenoid 78, the foreign matter prevention shutter 73 rotates clockwise (direction α10 in FIG. 8) and contacts. The part 73b closes the conveyance path (closed state). As a result, entry of foreign matter into the roll paper transport unit 33 is prevented.

  The foreign matter prevention shutter 73 is in the open state when the first transport roller 71b and the second transport roller 72b are in the contact position, that is, when the roll paper storage unit 32 is mounted on the roll paper transport unit 33. In this case, the roll paper R is conveyed to the roll paper printing unit 34 (see FIG. 2) inside the ticket issuing unit 7 using the driving force generated by the motor 74 (see FIG. 4).

On the other hand, the foreign matter prevention shutter 73 is in the closed state when the first transport roller 71b and the second transport roller 72b are in the separated positions, that is, the roll paper storage unit 32 is detached from the roll paper transport unit 33. When the roll paper R is not transported, such as when the automatic ticket vending machine 1 (see FIG. 1) is turned off, or when the roll paper R is transported while being tilted, the roll paper R It is time to correct the tilt.
Thereby, when the roll paper R is not transported, foreign matter can be prevented from entering the roll paper transport section 33.

Details of the control unit 40 will be described in the operation of the ticket issuing unit 7 to be described later.
Above, description about the structure of the ticket issuing part 7 which concerns on 1st Embodiment is complete | finished.

<Operation of the ticket issuing unit according to the first embodiment>
With reference to FIG. 3 thru | or 9, the paper feeding operation | movement of the roll paper R in the ticket issuing part 7 is demonstrated.
First, the clerk pulls out the roll paper storage unit 32 in the α1 direction, sets the roll paper R in the roll paper storage unit 32 so that the tip of the roll paper R abuts against the stopper 54, Push in the α2 direction. The opening / closing block 31b pushes down the post 56 attached to the stopper 54, and the stopper 54 is opened in conjunction with the post 56 being pushed down (see FIG. 7). Further, the paper feed conveyance roller 53 is connected to the first conveyance roller 71 via a gear 53a.

  Subsequently, when the control unit 40 receives an ON signal that detects the leading edge of the roll paper R from the set detection sensor 57, the control unit 40 displays information indicating that the roll paper R can be loaded into the ticket issuing unit 7. 5 (FIG. 1). On the other hand, when the control unit 40 does not receive the ON signal that detects the leading edge of the roll paper R from the set detection sensor 57, the control unit 40 rotates the roll fulcrum portion 52 of the roll paper storage unit 32 in the transport direction for a certain period of time, The reception of the ON signal from the detection sensor 57 is monitored. When the roll fulcrum portion 52 is rotated in the transport direction for a certain time and still does not receive the ON signal, the control unit 40 provides information indicating that the roll paper R is not correctly set in the roll paper storage unit 32. The information is displayed on the operation unit 5 to prompt the staff to reset the roll paper R.

Subsequently, the control unit 40 monitors the reception of the roll paper R loading instruction input via the clerk operation unit 5. Upon receiving the loading instruction, the control unit 40 transmits a suction operation instruction to the solenoid 78 and moves the transport rollers 71b and 72b in the upward direction (direction α7 in FIG. 8) to move to the contact position. Then, the conveyance path is opened by rotating the foreign matter prevention shutter 73 counterclockwise (direction α9 in FIG. 8). Then, the control unit 40 drives the motor 74 to rotate the paper feed conveyance roller 53 and the conveyance rollers 71 and 72 to convey the roll paper R to the front of the roll paper printing unit 34.
Above, description about operation | movement of the ticket issuing part 7 which concerns on 1st Embodiment is complete | finished.

As described above, the ticket issuing unit 7 as the ticket issuing device according to the first embodiment is configured to include the foreign matter prevention shutter 73 that is interlocked with the UP / DOWN operation of the transport rollers 71b and 72b. The foreign matter prevention shutter 73 is lowered when the roll paper R is transported, but is always raised when the roll paper R is not transported, so that the foreign matter enters even when the power is turned off or the roll paper storage unit 32 is detached. Can be prevented.
For this reason, the ticket issuing unit 7 as the ticket issuing device according to the first embodiment can always prevent foreign matter from entering without being affected by the state of the device. Moreover, since it is not necessary to increase the number of electrical components such as actuators, it can be realized at low cost.

[Second Embodiment]
In the ticket issuing unit 7 as the ticket issuing device according to the first embodiment, two set detection sensors 57 are arranged on both sides of the conveyance path so as to face each other (see FIG. 6). When roll paper is detected, an ON signal is output.
Here, when the clerk sets a new roll paper, the tip of the roll paper may stick out or the tip of the roll may be partially recessed to tear off the glued part of the roll paper by hand. In this case, there is a problem that the set detection sensor 57 cannot detect the roll paper R even though the roll paper R is set (see FIGS. 10 and 11).

  On the other hand, in the ticket issuing unit 7A as the ticket issuing device according to the second embodiment, the set detection sensor 57A is arranged in relation to the position where the stopper 54 is installed. Specifically, the set detection sensor 57A is disposed in front of (immediately before) the stopper 54 and on the same straight line with respect to the transport direction. Accordingly, the set roll paper R can be detected regardless of the shape of the leading edge of the roll paper R that is different each time.

<Configuration of ticket issuing unit according to the second embodiment>
With reference to FIG.12 and FIG.13, the structure of 7 A of ticket issuing parts (not shown) which concerns on 2nd Embodiment is demonstrated. FIG. 12 is an enlarged schematic cross-sectional view of a main part of the roll paper storage unit (detached state) according to the second embodiment (when the tip has a protruding shape). FIG. 13 is an enlarged schematic cross-sectional view of the main part of the roll paper storage unit (detached state) according to the second embodiment (when the tip has a concave shape).

  The difference between the ticket issuing unit 7 according to the first embodiment and the ticket issuing unit 7A according to the second embodiment is that, in the first embodiment, two set detection sensors 57 are arranged on both sides of the conveyance path. However (see FIG. 6), in the second embodiment, a single set detection sensor 57A is arranged in front of (in front of) the stopper 54 and on the same straight line with respect to the transport direction.

  In addition, there is a concern that by monitoring the medium with a single sensor, the inclination of the roll paper R cannot be detected more strictly than in the first embodiment, but the conveyance path width is set to “medium width variation” and “product”. By setting the minimum width in consideration of “variation”, it is possible to ensure the same performance as monitoring two sensors.

  Thus, even when the leading end of the roll paper protrudes as shown in FIG. 12 or when a part of the leading end of the roll paper R is recessed as shown in FIG. 13, the roll paper R is pushed in until it hits the stopper 54. Thus, the set detection sensor 57A can always detect the roll paper R.

As described above, the ticket issuing unit 7A as the ticket issuing device according to the second embodiment arranges one set detection sensor 57A before (immediately before) the stopper 54 and on the same straight line with respect to the transport direction. Thus, the roll paper can be detected without being affected by the tip shape of the roll paper R.
Further, since the ticket issuing unit 7A as the ticket issuing device according to the second embodiment can reduce the number of sensors from two to one, a cost reduction effect is also obtained.

[Third Embodiment]
As shown in FIG. 14, the ticket issuing unit 7 as the ticket issuing device according to the first embodiment is configured such that when the roll paper R is tilted and set and conveyed as it is, the roll paper R is changed by the biting operation of the conveyance roller. Correct the tilt. The foreign matter prevention shutter 73 opens and closes the conveyance path in conjunction with the UP / DOWN operation of the conveyance rollers 71b and 72b, so that the tip of the free end of the foreign matter prevention shutter 73 slightly touches the lower surface of the roll paper R. To make contact (sliding contact).

  Therefore, depending on the material or the like of the roll paper R, as shown in FIG. 15, the foreign matter prevention shutter 73 may scratch the area R1 that is the magnetic writing area or the print writing area of the roll paper R, resulting in poor magnetic reading. There was a problem that caused printing loss.

  On the other hand, the ticket issuing unit 7B as the ticket issuing device according to the third embodiment arranges the foreign matter prevention shutter 83 at a position that does not contact the magnetic writing area of the roll paper R or the region R1 that is the printing writing area. As a result, even if the foreign matter prevention shutter 83 opens and closes the conveyance path by the biting operation of the conveyance roller, no scratch S is attached to the magnetic writing area or the printing writing area R1 of the roll paper R (see FIG. 16). ).

<Configuration of ticket issuing unit according to the third embodiment>
In the ticket issuing unit 7B (not shown) as a ticket issuing device according to the third embodiment, the foreign matter prevention shutter 73 does not contact the magnetic writing area or the printing writing area R1 of the roll paper R (FIG. 16). The shutter support portion 73a is pivotally supported on the housing 31 (see FIG. 8).

  As described above, the ticket issuing unit 7B as the ticket issuing device according to the third embodiment arranges the foreign matter prevention shutter 73 outside the area R1 which is the magnetic writing area or the print writing area of the roll paper R. The area R1 that is the magnetic writing area and the print writing area of the roll paper R is not scratched.

[Fourth Embodiment]
The ticket issuing unit 7B as the ticket issuing device according to the third embodiment arranges the foreign matter prevention shutter 73 outside the area R1 which is the magnetic writing area and the print writing area of the roll paper R, so that the roll paper R The area R1 which is the magnetic writing area and the print writing area is prevented from being scratched.

  However, when the region R1 that is the magnetic writing area or the printing writing area occupies the entire roll paper R, or due to design restrictions, the foreign matter prevention shutter 73 is placed in the magnetic writing area of the roll paper R or the region R1 that is the printing writing area. In the case where it cannot be arranged outside, there still remains a problem that the foreign matter prevention shutter 73 scratches the region R1 which is the magnetic writing area or print writing area of the roll paper R.

  In contrast, the ticket issuing unit 7C as the ticket issuing device according to the fourth embodiment prevents the roll paper R from being scratched by using the escape mechanism.

<Configuration of ticket issuing unit according to the fourth embodiment>
With reference to FIG.17 and FIG.18, the structure of 7 C of ticket issuing parts (not shown) which concerns on 4th Embodiment is demonstrated. FIG. 17 is a schematic longitudinal sectional view of a foreign matter prevention shutter according to the fourth embodiment. FIG. 18 is an enlarged schematic vertical cross-sectional view of a main part of a foreign matter prevention shutter according to the fourth embodiment.

  The difference between the ticket issuing unit 7 according to the first embodiment and the ticket issuing unit 7C according to the fourth embodiment is that the configuration of the foreign matter prevention shutter 73 and the link bar 77 is different from the foreign matter prevention shutter 83 and link shown in FIGS. 17 and 18. The bar 87 is changed.

  The foreign matter prevention shutter 83 includes a shutter support portion 83a that is pivotally supported by the housing 31, and a projection portion 83b (see FIG. 18) as a closing member that opens and closes the conveyance path according to the rotation state and prevents the foreign matter from entering. , And a substantially L-shaped plate member formed with an arc shape and a contact portion 83c that contacts the lower surface of the roll paper R.

The foreign matter prevention shutter 83 is connected to a reset spring 90 as an elastic member that generates a biasing force in a direction in which the foreign matter prevention shutter 83 is pushed up (α10 direction). The biasing force of the reset spring 90 is set to a minimum force that allows the foreign matter prevention shutter 83 itself to lift.
Further, the link post 89 to which the foreign matter prevention shutter 83 is connected is connected to the link bar 87 through a square hole 87 a formed in the link bar 87. The square hole 87a formed in the link bar 87 is a force by which the foreign matter prevention shutter 83 presses the roll paper R when the foreign matter prevention shutter 83 contacts the roll paper R and the link post 89 moves in the β1 direction. Are formed so as to have only the urging force of the reset spring 90.

  Hereinafter, a mechanism realized by the square hole 87 a formed in the link bar 87 and the reset spring 90 connected to the foreign matter prevention shutter 83 is referred to as an “escape mechanism”. With this escape mechanism, the rotation of the foreign matter prevention shutter 83 stops at the roll paper R, and it is possible to prevent problems such as damaging the roll paper R and further opening a hole.

  The stopper 54 may also be configured to include the escape mechanism described above, similar to the foreign matter prevention shutter 83. Thereby, it is possible to prevent the stopper 54 from scratching the roll paper R when the roll paper storage unit 32 is detached while the roll paper R remains in the roll paper transport unit 33.

As described above, the ticket issuing unit 7C as the ticket issuing device according to the fourth embodiment has a configuration in which the tip of the foreign matter prevention shutter 83 has an arc shape and includes an escape mechanism. Can be prevented.
Further, since the projection shape is formed on the surface of the foreign matter prevention shutter 83 where the foreign matter collides, the foreign matter can be prevented from entering (FIG. 18).
