Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a coupon / ticket issuing machine. More specifically, the present invention relates to a coupon / ticket issuing machine that issues coupons and tickets by printing on paper.

[0002]

2. Description of the Related Art As a device for issuing coupons and tickets on the spot according to operations, there is a coupon / ticket issuing machine. This coupon / ticket issuing machine prints a sheet set in a paper feeding unit, then cuts a printed portion, and issues a cut piece as a coupon or ticket.

[0003] By the way, due to the layout of each component of the coupon / ticket issuing machine, there is a case where it is desired to convey a cut piece obtained by cutting the roll paper in a direction different from the feed direction of the roll paper and issue it as a coupon ticket. . In this case, since the direction of the rotation axis of the roller for feeding the roll paper (roller-side roller) and the roller for feeding the cut piece (cut-side roller) are different, the cut-side roller is retracted with the cut-side roller retracted. It is necessary to feed the roll paper in between, and after cutting the roll paper, it is necessary to return the cut-side roller to carry it. In a conventional coupon / ticket issuing machine, a drive source such as a dedicated motor is used to retract the cut one side roller.

In addition, in order to detect whether or not the roll paper has been fed between the retracted one-side rollers, the presence or absence of the roll paper is directly detected in a non-contact manner using an optical sensor.

[0005]

However, in the conventional coupon / ticket issuing machine, a dedicated driving source such as a motor is used to retract the one-sided roller, so that the number of parts increases and the manufacturing cost increases. As it gets higher,
This has led to an increase in the size of the device and an increase in power consumption, which has been contrary to the demand for energy saving. In addition, since the cutting one side roller is retracted by a dedicated driving source, a special control is required to link the retracting of the roller and the cutter operation.

Furthermore, since the presence / absence of roll paper is directly detected in a non-contact manner using an optical sensor, a detection error may occur due to a difference in light transmittance due to a difference in type of paper powder or roll paper. was there.

The present invention provides a coupon / ticket issuing machine which does not require a dedicated power source for retracting the rollers and can detect the presence or absence of roll paper without being affected by differences in paper dust or light transmittance. The purpose is to do.

[0008]

In order to achieve the above object, according to the first aspect of the present invention, in a coupon / ticket issuing machine which prints on paper and issues coupons and tickets, the paper is conveyed in a linear state. The linear transport unit has a cutter unit that cuts the paper at predetermined intervals, a drive mechanism that linearly moves the cutter holding frame of the cutter unit from the home position to the end position, and when the paper enters the linear transport unit, The paper feed roller and a roller retreat mechanism for retreating the pad roller from the transport path are provided.

Therefore, when paper is fed to the linear transport section, the roller retracting mechanism retracts the paper feed roller and the pad roller from the transport path immediately before the paper enters the linear transport section, thereby enabling paper insertion. I do. The drive mechanism causes the cutter unit to move linearly, and cuts the portion of the paper that is contained in the linear transport section. After cutting, the cut pieces are conveyed by a feed roller and a pad roller and issued as a coupon ticket.

According to a second aspect of the present invention, in the coupon / ticket issuing machine, the roller retracting mechanism retracts the roller at the home position of the cutter during a play period of the cutter by the driving force of the driving mechanism of the cutter.

Therefore, when the cutter unit is transported to the home position, the roller retracting mechanism operates to retract the feed roller and the pad roller. The roller retracting mechanism retracts the feed roller and pad roller during the play period immediately before the cutter unit returns to the home position. Paper can be inserted into the linear transport section.

Further, in the coupon / ticket issuing machine according to the third aspect, the paper guide plate has a roller opening and a sensor lever opening, and these openings are formed in a shape in which the paper is hardly caught.

The paper sent to the linear transport section is inserted while being guided by a paper guide plate. The paper guide plate is provided with a roller opening for projecting a feed roller and a sensor lever opening for projecting a lever of a sensor for detecting paper. Each opening has a shape in which the paper is hardly caught, so that the paper is smoothly inserted.

Further, in the coupon / ticket issuing machine according to the fourth aspect, the sensor has a mechanical lever, and can detect the movement of the paper in the paper transport direction and the direction perpendicular to the paper transport direction. Therefore, the movement of the paper in the paper transport direction and the direction perpendicular to the paper transport direction can be detected by the movement of the mechanical lever.

Further, in the coupon / ticket issuing machine according to the fifth aspect, the feed roller and the pad roller are held in a pressed state when the cutter is operated. Therefore, the cutting can be performed in a state where the paper is sandwiched and fixed by the feed roller and the pad roller.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail based on the best mode shown in the drawings.

1 to 12 show an example of an embodiment of a coupon / ticket issuing machine to which the present invention is applied. The coupon / ticket issuing machine issues a coupon or a ticket by printing on paper 1, and supplies a paper 1 to supply paper 1, a printer 3 to print on paper 1, a paper 1 and a linear transport section 6 having a cutter 5 for transporting the paper 1 in a linear state and cutting the paper 1 into predetermined widths. , The printer unit 3 and the paper feed unit 2 in the vertical direction.

The paper supply unit 2 that supplies the roll paper 1 guides the roll paper 1, a paper receiving unit 7 that receives the roll paper 1, a paper feed roller 10 that transports the roll paper 1 to the printer unit 3, and the roll paper 1. A flat end portion 9 is provided on the roll receiving portion 7 for detecting that the outer diameter of the roll paper 1 has become equal to or smaller than a predetermined diameter. When the end of the roll paper 1 passes through the concave portion 29, the lever 30 of the sensor rotates to provide an end sensor 8 for detecting the paper end.

In this embodiment, two roll receivers are arranged as the roll receiver 7, and the roll paper 1 is set on the two roll receivers 7. The roll paper 1 has a guide portion 28
Is supplied to the printer unit 3 through the space between the paper feed unit feed roller 10 and the pinch roller 11 while being guided. The paper feed roller 10 is driven by a motor 23.

The end sensor 8 detects the end of the roll paper 1 (the roll paper 1 has run out) by detecting the end of the roll paper 1. That is, when the roll paper 1 is fed to the printer unit 3 by the paper feed unit feed roller 10 and the pinch roller 11 through the concave portion 29 in which the lever 30 can rotate while being guided by the guide unit 28, the lever 30
Is pushed by the roll paper 1 and rotated to the position shown by the solid line in FIG. On the other hand, when the roll paper 1 is exhausted and the roll paper 1 passing through the concave portion 29 of the guide portion 28 runs out, the roll paper 1
3 returns to the position shown by the two-dot chain line in FIG. The end sensor 8 optically detects the position of the lever 30 to detect a break in the roll paper 1.

As described above, since the end sensor 8 detects the break of the paper by bringing the end of the lever 30 into contact with the roll paper 1, even if the roll paper 1 having a large light transmittance is used, Also, the presence / absence of the roll paper 1 can be reliably detected, and the presence / absence of the roll paper 1 can be reliably detected without being affected by the difference in light transmittance caused by the difference in the type of the roll paper 1. Further, since the presence or absence of the roll paper 1 is detected based on the rotation position of the lever 30, the end sensor 8 itself can be arranged at a position distant from the roll paper 1, and the end sensor 8 can be rolled well without being affected by paper dust. Paper 1
Can be detected.

The near-end sensor 9 includes an arm 32 and a roller 31 rotatably attached to the tip of the arm 32.
have. The near end sensor 9 is arranged between the two roll receivers 7. In a state where the roll paper 1 is sufficiently left and its outer diameter is large, as shown by a solid line in FIG. 3, the roll paper 1 and the roller 31 are sufficiently separated. Therefore, the near-end sensor 9 remains off. On the other hand, if the remaining amount of the roll paper 1 becomes small and its outer diameter becomes small, as shown by a two-dot chain line in FIG. The arm 32 is pushed down. Thereby, the near end sensor 9 is turned on, and detects that the roll paper 1 is almost out of paper.

As described above, the near-end sensor 9 is
1 is brought into direct contact with the roll paper 1 to detect that the paper is nearly out, so that the remaining amount of the roll paper 1 can be set to a predetermined value without being affected by paper dust as in the case of optical detection. Can be detected.

The paper feed unit 2 is provided at the end face 1 c of the roll paper 1.
Is pressed in the width direction of the roll paper 1. The pressing block 34 is supported by two guide bars 35 and is movable in the width direction of the roll paper 1. The pressing block 34 applies a certain pressing force to the end surface 1 c of the roll paper 1 by the pressing plate 36. Of the roll paper 1 is held at a predetermined distance from the end surface 1c of the roll paper 1, and a brake portion 37 for generating a braking force on the guide bar 35 is provided.

A spring 40 is provided between the pressing block 34 and the pressing plate 36, and a spring 41 is provided between the pressing block 34 and the brake portion 37. A slight gap δ is provided between the pressing block 34 and the brake part 37.

When positioning the roll paper 1 by the pressing block 34, first, the roll paper 1 is placed in the roll receiver 7.
After being placed on the upper part, the pressing block 34 is moved (forward) while forcibly sliding the brake part 37 with respect to the guide bar 35. Then, one end surface 1 c of the roll paper 1 is sandwiched by the pressing plate 36, and the other end surface 1 c is sandwiched by the reference surface 38. When the hand is released from the pressing block 34 in this state, the pressing block 34 is retracted by the elastic force of the spring 40. Since the braking force of the brake portion 37 is stronger than the elastic force of the spring 40, the brake portion 37 does not retreat, and the pressing block 34 extends the spring 41 and retreats within the range of the gap δ and stops at a position where the forces are balanced. I do. Therefore, the roll paper 1 is pressed by the pressing plate 36 to the reference surface 38.
Is pressed by a predetermined amount of force and positioned. In this state, the end surface 34a of the pressing block 34 is separated from the end surface 1c of the roll paper 1, and the rotation resistance of the roll paper 1 becomes small.

Even when a roll paper 1 having a different width is used, the pressing block 34 is moved according to the width of the roll paper 1 so as to abut on the end surface 1c of the roll paper 1 to thereby reduce the width. Regardless of the difference, the roll paper 1 can be properly positioned. Further, since the pressing plate 36 is pressed against the end face 1c of the roll paper 1 by the elastic force of the spring 40, the roll is not affected by the difference in the width of the roll paper 1 or the difference in the force for moving the pressing block 34 during setting. The paper 1 can always be positioned with a constant force.

A sensor 39 for detecting the presence or absence of the roll paper 1 is provided on an end face 34a of the pressing block 34 which is in contact with the end face 1c of the roll paper 1 on the other end face 1c of the roll paper 1.
A sensor 63 for detecting the presence or absence of the roll paper 1 is provided on the wall (reference surface) 38 of the unit with which the roll paper 1 contacts. When the roll paper 1 is set on the roll receiver 7 and positioned by the pressing block 34, the rod 3 of the sensors 39 and 63
9a and 63a are pushed in. Thereby, the sensors 39 and 63 detect the roll paper 1.

The printer unit 3 has a printer head that moves in the width direction of the roll paper 1, and prints coupons and tickets on the leading end of the roll paper 1 while feeding the roll paper 1 by the printer feed roller 12. Then, the roll paper 1 that has passed through the printer unit 3 is reversed through the reversing unit 4 and then proceeds to the linear transport unit 6. The printer feed roller 12 is driven by a motor 24.

The linear transport unit 6 includes a cutter holding frame 42
And cuts the sent roll paper 1 in its width direction. The worm engaging portion 43 of the cutter holding frame 42 is engaged with a screw rod (worm) 17 rotated by the motor 16, and is guided by the two guide shafts 18 arranged vertically by the rotation of the screw rod 17. To move linearly in the width direction of the roll paper 1,
The roll paper 1 is cut at a predetermined length from its leading end. Since the cutting is performed after printing on the roll paper 1, only the printed portion can be cut. That is,
It is possible to form a cut piece 1a that is printed to the end. Further, since the roll paper 1 is sent to the linear transport section 6 in a state, the feeding mechanism can be simpler than in the case of feeding the cut strip, and the paper jam can be prevented. The cut piece (paper medium after cutting) 1a becomes a coupon or ticket.

The cutter 5 of the linear transport section 6 can be retracted. That is, the linear transport section 6 has a cutter unit 33 that cuts the roll paper 1 at predetermined intervals, engages with the worm engaging section 43 provided on the cutter holding frame 42 of the cutter unit 33, and A holding mechanism 45 for linearly moving the cutter holding frame 42, and a cutter unit 33 held by the holding mechanism 45 when the cut paper medium (cut piece) 1a is ejected from the passage of the cut piece 1a. And a cutter unit retracting mechanism 46 for retracting the unit 33.

The cutter unit retracting mechanism 46 is a solenoid for rotating the holding mechanism 45 via the link 47. When the solenoid 46 pulls the link 47 as shown by a two-dot chain line in FIG. The cutter 5 is rotated about the cutter unit 49 to retract the cutter 5 together with the cutter unit 33. That is, the cutter 5 is retracted while maintaining the engagement relationship between the screw rod 17 of the holding mechanism 45 and the worm engaging portion 43 of the cutter holding frame 42. As described above, since the drive system for linearly moving the cutter holding frame 42 is not cut off in the middle, the retracting mechanism is simplified, and the manufacturing cost can be reduced.

The cutter 5 is a cutter blade that cuts the roll paper 1 across it. For example, a wire roller 44 is attached to the lower cutter blade 5. This wire roller 44 is parallel to the screw rod 17,
That is, the wire 48 stretched in the direction of the linear movement of the cutter holding frame 42 is wound therearound, and the linear movement of the cutter holding frame 42 is converted into a rotational movement by the lower cutter blade 5 via the wire roller 44. introduce. Since the roll paper 1 is cut while rotating the lower cutter blade 5, the cutting performance of the roll paper 1 is improved.

The linear transport section 6 is provided with a security adding means 13, and the cut piece 1 a is transported to the security adding means 13 by the roller 14 and the pad roller 51. In this embodiment, the security adding unit 1
Reference numeral 3 denotes a hot stamp unit for attaching a hologram foil which is difficult to copy. The cut piece 1a to which security is added is issued from the ticket issuing port 25 as a coupon or a ticket.

On the other hand, the cut piece 1a in which a printing error or the like is found before issuing a ticket is transported by the roller 14 and the pad roller 51 of the linear transport section 6 to the waste ticket port 26 provided on the opposite side to the ticket issuing port 25. Is discharged. Here, immediately after the roll paper 1 is cut, the cutter blade 5 has moved to the end position P3 on the front side of the waste ticket slot 26.
Therefore, in order to avoid interference between the cut piece 1a conveyed to the waste ticket slot 26 and the cutter blade 5, the cut piece 1a
When carrying a to the waste ticket slot 26, the cutter unit avoidance mechanism 46 is operated to retract the cutter blade 5. By retracting the cutter blade 5, the cut piece 1a
Interference with the cutter blade 5 can be avoided, so that the waste ticket slot 26 can be arranged on the opposite side of the ticket issuing slot 25, resulting in a layout excellent in space efficiency.

The feed roller 14 of the linear transport section 6 is driven by a motor 15. Also, feed roller 1
4 and the pad roller 51 can be retracted. That is, when the roll paper 1 sent from the reversing unit 4 enters the linear transport unit 6, the linear transport unit 6 retracts the feed roller 14 and the pad roller 51 of the roll paper 1 from the transport path 53. 52 are provided. The roller retracting mechanism 52 is driven by a driving mechanism (a mechanism that linearly moves the cutter holding frame 42 including the motor 16, the screw rod 17, and the worm engaging portion 43) that linearly moves the cutter 5. The feed roller 14 and the pad roller 51 are retracted during the play period of the cutter 5 at the home position P1 of 42 (between the home position P1 and the cut start position P2).

That is, after the cutting of the roll paper 1, the cutter holding frame 42 is returned from the end position P3 to the home position P1 by the rotation of the screw rod 17, but when the cutter holding frame 42 reaches the cutting start position P2. The lever abuts on the feed roller side lever 54 and the pad roller side lever 55, and thereafter these levers 54, 5
While rotating 5, the cutter holding frame 42 returns to the home position P1.

The rotation of the feed roller side lever 54
Lever 5 with feed roller 14 attached via 6
7 to rotate each lever 57 to retract the feed roller 14 from the roller opening 58 a of the paper guide plate 58. Further, the rotation of the pad roller side lever 55 is transmitted to the lever 60 to which the pad roller 51 is attached via the link 59, and the respective levers 60 are rotated to move the pad roller 51 from the roller opening of the paper guide plate 62. Evacuate. When the roll paper 1 is fed into the linear transport unit 6, since the cutter holding frame 42 has moved to the home position P1, the paper guide plate 58, the paper guide plate 58, and the feed roller 14 and the pad roller 51 are completely retracted.
The roll paper 1 can be inserted into the transport path 53 between the rollers 62.

The feed roller lever 54 is constantly urged by a return spring (not shown) in a direction in which the feed roller 14 projects from the roller opening 58a. The pad roller side lever 55 is constantly urged by a return spring (not shown) in a direction in which the pad roller 51 projects from the roller opening. Therefore, when the cutter holding frame 42 moves away from the home position P1, the feed roller 14 and the pad roller 51 project into the transport path 53 by the urging force of the return spring.

As described above, the feed roller 14 and the pad roller 51 can be retracted and projected by the movement of the cutter holding frame 42, so that a dedicated driving source and a driving force transmission mechanism for retracting and projecting are not required. For this reason,
The number of parts can be reduced to reduce the manufacturing cost, the size of the device can be reduced, and it is advantageous in terms of energy saving. Further, since the operations of the cutter holding frame 42 and the roller retracting mechanism 52 can be mechanically synchronized, the control thereof is also simplified.

When the roll paper 1 is cut,
Using the play period in which the cutter holding frame 42 is moved from the home position P1 to the cut start position P2, the feed roller 14 and the pad roller 51 are transported along the transport path 5.
3 can be projected. For this reason, cutting can be started in a state where the roll paper 1 is sandwiched and fixed between the rollers 14 and 51. That is, when the cutter is activated,
Since the feed roller 14 and the pad roller 51 are held in a pressure-bonded state, it is possible to prevent the sheet from shifting at the time of cutting.

By retracting the feed roller 14 and the pad roller 51 in this manner, the roll paper 1 can be inserted into the transport path 53 in a direction orthogonal to the direction in which the cut pieces 1a are fed by the rollers 14, 51. However, the roller opening 58a and the sensor lever opening 58b provided in the paper guide plate 58 are formed in a shape in which the roll paper 1 is hardly caught. For example, as shown in FIG.
The rear side edge 58c of the roller opening 58a has a V-shape and is inclined with respect to the insertion direction of the roll paper 1 so that the leading end of the roll paper 1 is hardly caught. Further, the sensor lever opening 58b is inclined by 45 degrees with respect to the insertion direction of the roll paper 1 and the transport direction of the cut piece 1a, so that the leading end of the roll paper 1 is hardly caught.

The sensor lever opening 58b has a sensor 6 for detecting the roll paper 1 or the cut piece 1a after cutting.
One mechanical lever 61a penetrates. Since the sensor lever opening 58b is formed at an angle of 45 degrees with respect to the insertion direction of the roll paper 1 and the transport direction of the cut piece 1a, the mechanical lever 61a rotates when the roll paper 1 is inserted or the cut piece 1a is transported. Move. Therefore, the sensor 61 can detect the insertion of the roll paper 1 and the conveyance of the cut piece 1a by the movement of the mechanical lever 61a. That is, it is possible to detect the movement of the cut piece 1a in the transport direction of the roll paper 1 and the direction orthogonal to the transport direction.

The tip of the mechanical lever 61a is rounded, and the mechanical lever 61a is smoothly rotated by the roll paper 1 or the cut piece 1a. The other paper guide plate 62 also has a sensor lever opening 62 a having the same shape as the paper guide plate 58.

When the roll paper 1 is cut by the cutter 5 of the linear transport unit 6, the roll paper 1 is fed back to a position where it is displaced from the printer feed roller 12 of the printer unit 3. At this time, the paper feed roller 10 of the paper feed unit 2 is released, and the roll paper 1 is slackened (FIG. 2). Here, the release of the paper feed unit feed roller 10 will be described. Solenoid 1
When the lever 9 is turned off, the first lever 20 is swung by the return spring 22, and the second lever 21 is swung against the urging force of the return spring 50 to feed the pinch roller 11 to the sheet feeding unit. Separated from the roller 10.
As a result, the feed unit feed roller 10 and the pinch roller 11
Is released, the paper feed unit feed roller 10 is released.

When the solenoid 19 is turned on, the first lever 20 swings away from the second lever 21 against the urging force of the return spring 22. Therefore, the second lever 21 is urged by the return spring 50 in a direction in which the pinch roller 11 is pressed against the feed roller 10.

When a coupon ticket is to be issued next, the printer unit 3 outputs the slack roll paper 1
Is performed while the printer is fed by the printer feed roller 12. That is, in a state where the paper feed unit feed roller 10 of the paper feed unit 2 is released, the roll paper 1 is fed by the printer feed roller 12.
Printing is performed while feeding the slack portion 1b. When the slack portion 1b is fed, since the feed resistance is extremely small, printing can be performed while feeding the roll paper 1 at a constant speed, and high-quality printing can be performed.

Thereafter, the printed roll paper 1 is placed in the reversing unit 4.
, And then sent to the linear transport unit 6 and issued as a coupon ticket in the same manner as described above.

In this coupon / ticket issuing machine, the printing operation of the printer unit 3 and the operation of the linear transport unit 6 are separated. The operation of the linear transport unit 6 is, for example, a security adding operation by the hot stamp unit 13.
The hot stamp unit 13 is driven by a motor 27, which is different from the motor 24 which is a driving source of the printer unit 3. The printer unit 3
Performs printing on the roll paper 1, whereas the hot stamp unit 13 attaches the hologram foil to the roll paper 1.
Is a cut piece 1a cut from Therefore, the printing operation of the printer unit 3 and the security adding operation of the linear transport unit 6 can be separated. By separating these operations and making them independent, these operations can be performed at the same time, and the coupon and the coupon to be issued at the same time while performing the security adding operation on the first cut piece 1a are simultaneously performed.
Tickets can be printed, multiple coupons
The time required for issuing a ticket is greatly reduced.

The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the gist of the present invention.

[0053]

As described above, in the coupon / ticket issuing machine according to the first aspect, the linear transport unit that transports the paper in a linear state has the cutter unit that cuts the paper at a predetermined width. It has a drive mechanism that moves the cutter holding frame linearly from the home position to the end position, and a roller retract mechanism that retracts the paper feed roller and pad roller from the transport path when paper enters the linear transport unit. By using the linear motion of the cutter unit, the feed roller and the pad roller can be retracted from the paper conveyance path. For this reason, a dedicated drive source for evacuation is not required, the number of parts can be reduced, the manufacturing cost can be reduced, and the device can be downsized.

In the coupon / ticket issuing machine according to the second aspect, the roller retracting mechanism retracts the rollers at the home position of the cutter during the play of the cutter by the driving force of the driving mechanism of the cutter. In the state returned to the home position, the retraction of the feed roller and the pad roller is completed. Therefore, the paper can be inserted after the feed roller and the pad roller have completely retracted, so that paper jams and the like can be prevented, and the paper can be transported smoothly.

In the coupon / ticket issuing machine according to the third aspect of the present invention, the paper guide plate has a roller opening and a sensor lever opening, and these openings are formed in a shape in which the paper is hardly caught. In addition, the paper can be more reliably prevented from being caught or jammed, and the paper can be transported more smoothly.

In the coupon / ticket issuing machine according to the fourth aspect, the sensor has a mechanical lever and can detect the movement of the paper in the paper transport direction and the direction perpendicular to the paper transport direction. Thus, the movement of the paper in the paper transport direction and the paper movement in the direction orthogonal to the paper transport direction can be detected. For this reason, it is possible to use an optical sensor with a mechanical lever, and it is possible to reliably prevent a detection error due to a difference in light transmittance of paper or paper dust, and to improve detection accuracy.

In the coupon / ticket issuing machine according to the fifth aspect, when the cutter is operated, the feed roller and the pad roller are held in a pressed state, so that the paper is fixed by the feed roller and the pad roller. Cutting can be performed, and paper misalignment during cutting can be prevented.

Further, in the coupon / ticket issuing machine according to the sixth aspect, a paper feeding section for supplying roll paper, a printer section for printing on paper, a reversing section for reversing the paper, and transporting the paper in a linear state. And a straight-line transport unit having a cutter for cutting the paper at predetermined widths. The straight-line transport unit is the lowermost portion, and the reversing unit, the printer unit, and the paper feed unit are vertically stacked in this order. Unit, reversing unit, printer unit, and paper feeding unit can be arranged so as to be stacked one on top of the other, reducing the size in the front-rear direction and the left-right direction. Therefore, the coupon / ticket issuing machine can be reduced in size, and for example, a coupon / ticket issuing machine suitable for use as a self-service terminal can be provided.
