The radius of the pulley 21 of the feed roller shaft 19 is about one half of the radius of the pulley 18 of the feed roller shaft 16. A toothed belt 22 is wound around both pulleys 18 and 21, and the toothed belt 22 is driven by transmitting the rotational force of a motor gear 23 a of a motor 23. The pulley of the feed roller shaft of the drive roller 12a also rotates by receiving the rotational force of the motor gear 23a of the motor 23. As a result, the drive roller 13a rotates at a speed approximately twice that of the drive rollers 11a and 12a.

Optical sensor 15 (15a, 15b, 15c)
Has a light emitting element and a light receiving element (not shown), and the controller 27, which will be described later, detects a change in the output of the light receiving element and determines whether or not the ticket paper 2 has been cut off at the perforations. In the present embodiment, the optical sensor 15c is arranged downstream of the feed roller B13, but the ticket paper 2 has perforations 2a.
It may be disposed between the feed roller B13 and the cutter roller 14 as long as the control unit 27 can determine whether or not it has been separated by. Further, in the present embodiment, the optical sensor 1
However, the type of sensor is not limited to the optical sensor.

The magnetic recording section 7 has a write head 7a for writing information on the magnetic stripe 2b of the ticket paper 2 and a read head 7b for reading information written on the magnetic stripe 2b.

The printing section 8 has a platen 8a, a thermal head 8b facing the platen 8a, and a thermal transfer ribbon 8c wound around a ribbon reel.
c is fed between the thermal head 8c and the transport path 3,
The thermal head 8b heats the thermal transfer ribbon 8c, and the ink in the heated portion is transferred to the printing surface of the ticket paper 2 to perform printing.

By the way, a blade 24 is provided in the conveying path 3 between the magnetic recording unit 7 and the printing unit 8 so as to be rotatable in the directions of arrows J and K. The ticket paper 2 that has passed through the recording unit 7 is guided to the printing unit 8.

Next, the control system of the embodiment will be described with reference to FIG. FIG. 5 is a control block diagram of the ticket processing apparatus in the embodiment.

The control unit 27 controls the entire ticket processing apparatus 1, and is connected to the optical sensor 15, the drive circuit 28, and the memory 29. A motor 23 and clutches 17a, 17b, 20 are connected to the drive circuit 28. In the memory 29, the ticket paper 2 handled by the ticket processing device 1
Size, perforation setting interval, etc., fixed time (t1, t2, t3) described later, and predetermined time (t4)
Is stored.

Next, the separating operation of the ticket paper 2 of the ticket processing apparatus 1 will be described with reference to FIGS.

First, the cover (not shown) of the ticket processing apparatus 1 is opened to store the ticket paper 2 in the hopper unit 4, and the leading end of the ticket paper 2 is inserted between the drive roller 11a and the driven roller 11b. Similarly, the ticket paper 2 is stored in the hopper portion 5, the leading end of the ticket paper 2 is inserted between the drive roller 12a and the driven roller 12b, and the cover is closed. When the cover is closed,
The control unit 27 connects the clutch 17a of the feed roller A11 and drives the motor 23. Therefore, the motor gear 2
The rotational force of 3a is transmitted via the toothed belt 22 and the pulley 18, the drive roller 11a rotates in the direction of arrow L,
The driven roller 11b is rotated in the direction of arrow M by the drive roller 11a. Similarly, the clutch 17b of the feed roller A12 is connected to transmit the rotational force of the motor gear 23a,
The drive roller 12a is rotated in the arrow L direction, and the driven roller 12b is rotated in the mark M direction. As a result, the ticket paper 2 inserted into both the feed rollers A11 and A12 is sent in the direction of the arrow C along the transport path 3. The control unit 27 uses the optical sensor 1
The motor 23 is stopped when the leading edge of the ticket paper 2 is detected by the output changes of 5a and 15b.

As described above, the setting of the ticket paper 2 in the ticket processing device 1 is completed, and the ticket issuing command standby state is entered.

When a ticket issuing command is input from an operation unit (not shown), the control unit 27 selects the hopper unit 4 or the hopper unit 5. When the hopper unit 4 is selected, the control unit 27 connects the clutch 17a of the feed roller A11, the clutch 17b of the feed roller A12 and the feed roller B13.
The clutch 20 is disengaged and the motor 23 is driven. As a result, the ticket paper 2 nipped by the feed roller A11 is guided by a paper guide (not shown) and is fed in the direction of arrow C. When the leading edge of the ticket paper 2 comes into contact with the central portion 14b of the cutter roller 14, the leading edge of the ticket paper 2 is fed in the arrow C direction while rotating the cutter roller 14 in the arrow M direction. Further, at this time, even if both leading ends of the ticket paper 2 come into contact with the surface of the cutter roller 14, the cutter roller 14 is rotating, so that the leading both ends of the ticket paper 2 are not caught by the cutter roller 14 and are conveyed in the conveying direction. Be guided to. Thereafter, the ticket paper 2 is guided by the paper guide and reaches the paper holding position E of the feed roller B13.

The control section 27 measures the drive time of the feed roller A11 from the time when the output of the optical sensor 15a changes by an internal counter (not shown), and at the timing when the leading edge of the ticket sheet 2 reaches the sheet clamping position E. , Disengage the clutch 17a of the feed roller A11, and feed roller B1
The clutch 20 of 3 is connected. As a result, the driving force of the motor 23 is transmitted to the driving roller 13a via the pulley 21, the driving roller 13a rotates in the direction of the arrow L at about twice the speed of the driving roller 11a, and the driven roller 13b moves by the driving roller 13a. Rotating in the M direction, the ticket paper 2 is nipped and conveyed by the feed roller B13. At this time, the ticket paper 2 is in contact with the central portion 14b of the cutter roller 14 and is curved. Further, the feed roller A11 holds the paper sheet 2, but since the clutch 17a is disengaged, the feed roller A11 is idled by the feed force of the feed roller B13.

While the ticket paper 2 is being conveyed in the above state, the ticket paper 2
When the head of the image passes the optical sensor 15c, the optical sensor 15c
Output changes, whereby the control unit 27 detects the leading position of the ticket paper 2. Since the information on the set interval of the perforation 2a is stored in the memory 29, the control unit 27 measures the driving time of the feed roller B13 from the time when the output of the optical sensor 15c changes from the internal counter based on this information. , The position of the perforation 2a is detected. When the perforation 2a is located at the point N shown in FIG. 4, the measurement time coincides with the fixed time (t1), and the control unit 27 connects the clutch 17a of the feed roller A11 for the fixed time (t2) at this timing. As a result, the feed roller A
11 is driven to rotate again by the motor 23, but a difference occurs between the rotation speed of the feed roller A11 and the rotation speed of the feed roller B13.
Is pulled by the feed roller B13 and separated at the perforations 2a to form a single ticket. The ticket paper 2 that has become a single ticket is further conveyed in the direction of arrow C by the feed roller B13.

The above-mentioned fixed time (t2) is the time taken until the perforation 2a is separated at the N point, and this time is measured by the internal counter. Then, when the time measured by the internal counter and the fixed time (t2) stored in the memory 29 match, that is, when the fixed time (t2) has elapsed, the clutch 17a is disengaged.

The control unit 27 uses an internal counter to measure the time from the time when the output of the optical sensor 15c changes, and when the measured time is less than a predetermined time (t4), that is, within a predetermined time (t4). When the rear end of the ticket paper 2 that has passed is passed through the optical sensor 15c, it is detected that the ticket paper 2 is separated at the perforations 2a. The predetermined time (t4) is set to be equal to or longer than the time it takes for the front end of the ticket paper 2 to pass the optical sensor 15c and the rear end separated by the perforation 2a to pass the sensor 15c.

After detecting that the first sheet has been separated,
When a plurality of tickets are continuously issued, since the position where the ticket paper 2 is cut off is known, the clutch 17a is re-engaged and the ticket paper 2 held by the feed roller A11 is indicated by the arrow C.
The fixed amount is conveyed in a predetermined direction, and the clutch 17 is disengaged and the clutch 20 is connected and disengaged at the timing when the leading edge of the ticket sheet 2 reaches the sheet sandwiching position E, as described above. Also,
When the ticket is not continuously issued, the clutch 20 is disengaged, the clutch 17a is connected, and then the motor 23 is rotationally driven in the opposite direction to sandwich the ticket paper 2 on the side sandwiched by the feed roller A11.
Is reversely conveyed in the direction opposite to the direction of the arrow C, and returned to the position in the ticket issuing command standby state.

The ticket paper 2 which has become a single ticket is the feed roller B.
It is further conveyed in the direction of arrow C by 13 and the magnetic recording unit 7
Sent to In the magnetic recording unit 7, the ticket paper 2 is first read by the read head 7b for the type of the ticket recorded in advance on the magnetic stripe 2b, and thereafter, the ticket issuing information is written by the write head 7a and conveyed to the printing unit 8. . At this time,
The blade 24 is rotating in the arrow J direction. When the printing unit 8 finishes printing, the sheet is discharged to the stacker unit 9.

By the way, when the rear end of the ticket paper 2 does not pass the optical sensor 15c within a predetermined time (t4) from the time when the output of the optical sensor 15c changes, that is, the cutter unit 6
When the ticket paper 2 cannot be separated at the perforations 2a in the above, the control unit 27 causes the motor 2
3 is stopped and the rotation of the feed roller B13 is stopped. Then, after disconnecting the clutch 20 of the feed roller B13 and connecting the clutch 17a of the feed roller A11, the motor 23 is rotationally driven in the reverse direction for a predetermined time (t3) to rotate the feed roller A11 in the reverse direction. As a result, the ticket paper 2 is conveyed in the reverse direction. At this time, the feed roller B13 holds the ticket paper 2, but since the clutch 20 is disengaged, the feed roller B13 idles in the opposite direction by the feed force of the feed roller A11.

When the motor 23 is driven in the reverse direction for a certain period of time (t3) and stopped, the perforation 2a for separating the ticket paper 2 stops at a position after passing the cutter roller 14. Then, the control unit 27 disconnects the clutch 17a, connects the clutch 20 and rotationally drives the motor 23 in the forward direction again, until the perforation 2a to be disconnected is positioned at the N point of the cutter roller 14.
The ticket paper 2 is conveyed in the direction of arrow C by the feed roller B13. When the controller 27 detects that the perforation 2a is located at the point N, the clutch 17 of the feed roller A11 is detected.
a is connected for a certain period of time (t2), and the perforation 2a is disconnected again as described above.

In this way, in the cutter unit 6, the ticket paper 2
Is unable to separate at the perforation 2a (when the separation fails), the motor 23 is driven in the reverse direction for a fixed time (t3) (reverse conveyance of the ticket paper 2), so that the first separation operation and reverse conveyance operation are performed. The eye 2a is slid on the central portion 14b of the cutter roller 14 to soften (easy to separate) the non-cut portion of the perforation 2a to perform the separating operation.

Since the operation of separating the ticket paper 2 of the hopper unit 5 and the operation at the time of failure of separation are the same as those described above, the description thereof will be omitted.

In this embodiment, the perforation 2 of the ticket paper 2 is used.
When a comes into contact with the central portion 14b of the cutter roller 14, the feed rollers A11, 12 and the feed roller B1
Since a difference in rotational speed is generated between the sheet 3 and the sheet 3 and the sheet is cut at the perforations 2a, it is not necessary to provide a cutter for cutting the ticket paper 2 on the cutter portion 6 and operate the cutter to separate the sheet 2 at the perforations 2a. Therefore, the structure is simpler than the case where a cutter or the like is provided, and the cost can be reduced.

In the present embodiment, the cutter roller 14 is
Since the diameter is increased from the end portion 14a to the central portion 14b of the roller, and the roller shaft 14c is rotatably attached, the feed roller A1
While the ticket paper 2 is being conveyed to the cutter roller 14 by 1, 12,
Even if both leading ends of the ticket paper 2 come into contact with the surface of the cutter roller 14, the traveling load of the ticket paper 2 does not occur. Further, while the ticket paper 2 is nipped and conveyed by the feed roller A11 or the feed roller A12 and the feed roller B13, the central portion 14b of the cutter roller 14 contacts the ticket paper 2, but the central portion 14b is formed over the roller surface. Since the cutter roller 14 is rotated instead of being a fixed member, the ticket paper 2 is not damaged.

In the present embodiment, the feed roller A1
1, 12 and the clutch 17a on the feed roller B13,
Since the transmission of the driving force of the motor 23 can be controlled by providing 17b and 20, information such as the perforation setting interval formed on the ticket paper to be handled is input to the control unit 27 in advance, If the perforations of the sheet are located at the N point of the cutter roller 14, the clutches 17a and 17b of the feed rollers A11 and A12 are connected,
It becomes possible to handle ticket papers of various sizes.

When the ticket processing device 1 handles only one type of ticket paper 2, when the perforation 2a of the ticket paper 2 is located at the N point, the top of the ticket paper 2a is the feed roller B13.
If the feed roller B13 is disposed at a position sandwiched between the feed rollers A11 and 12 and the feed roller B,
It is not necessary to provide 13 with clutches 17a, 17b, 20.

In the present embodiment, the feed roller A1
Since the feed roller B13 is rotated at a speed higher than that of the first and the second sheets 12, the ticket paper 2 is pulled and driven by the feed roller B13 for a certain time (t2) during which the cutter roller 14 separates the perforation 2a during the separating operation. It slips between the rollers 11a and 12a and the driven rollers 11b and 12b. Therefore, if the feed rollers A11, 12 have a torque limiter built-in and the feed rollers A12, 13 are applied with a feed force equal to or more than a set value, the feed rollers A11, 12 can be idled for a long period of time. It is possible to reduce wear on the surfaces of the driving rollers 11a and 12a and the driven rollers 11b and 12b due to use.

In the present embodiment, the rotation speed of the feed roller B13 is about twice as high as the rotation speed of the feed rollers A11 and A12, but the feed roller depends on the strength of the ticket paper 2 and the processing speed of the ticket processing apparatus 1. The rotation speeds of the A11 and A12 and the feed roller B13 change, and therefore, the speed difference between the feed rollers A11 and 12 and the feed roller B13 is not limited to this embodiment.

In the present embodiment, the pulley 18 and the pulley 2
1, the rotational speeds of the feed rollers A11, 12 and the feed roller B13 are changed by changing the radius of the pulley 1, but instead of changing the radius of the pulleys 18, 21, (pulley 1
8 and 21 have the same radius), for example, clutches 17a and 17
By using b as an electromagnetic spring clutch, and cutting the electromagnetic spring clutch (from the connected state) to forcibly stop the rotation of the feed rollers A11, 12 at the timing when the perforation 2a is located at the N point of the cutter roller 14, Feed rollers A11 and 12 and feed roller B
You may give a difference in the rotation speed with respect to 13. In this case, the clutch 20 can be omitted. Alternatively, not limited to the electromagnetic spring clutch, any method may be used as long as it can stop the rotation of the feed rollers A11 and 12 when the perforation 2a is located at the N point.

By the way, the timing for connecting (disconnecting) the clutches 17a, 17b (or electromagnetic spring clutches) of the feed rollers A11, 12 during the disengagement operation is as follows.
As shown in the present embodiment, it is not always necessary that the perforation 2a is located at the N point of the cutter roller 14, and it may be at the position where the perforation 2a is in contact with the central portion 14b upstream of the N point. For example, it can be cut off at the perforation 2a at any position. Therefore, in the present embodiment, it is not necessary to finely adjust the position of the cutter roller 14 for separating the ticket paper 2 and the perforation.

Next, modified examples of the present embodiment will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 6 is an explanatory diagram showing a modified example of the embodiment.

The ticket processing apparatus 1 has a paper guide 25 (25a, 25b) for guiding the ticket paper 2 in the conveying direction. The paper guide 25 includes a cutter roller 14 and a feed roller B13 as shown in the figure. The space is curved. The ticket paper 2 has a driving roller 13a and a driven roller 13b along this curve.
Guided between. A hole 26 for dropping paper dust is formed in the curved portion of the paper guide 25a on the drive roller 13a side. A paper powder storage box (not shown) is installed near the hole 26. The other structure is the same as that of the above-mentioned embodiment, and the description thereof is omitted. Further, the operation of separating the ticket paper 2 is also the same as that of the above-mentioned embodiment, and therefore its explanation is omitted.

When the ticket paper 2 is cut off at the perforations 2a by the cutter roller 14, paper dust is generated. In this modification, however, the paper dust is generated by forming the hole 26 in the curved portion of the paper guide 25a. It falls from the hole 26 and is stored in the paper powder storage box. Therefore, the paper dust is conveyed together with the ticket paper 2 and adheres to the feed roller B13 and the other conveying rollers 3a, so that the conveying force is reduced or the thermal head 8 is used.
It is possible to prevent the head from being damaged by being attached to b.

In the above-described modification, the paper dust generated by the separation of the ticket paper 2 is removed by spontaneously dropping it from the hole 26 formed in the paper guide 25.
A scraper or the like, which comes into contact with the width direction of the above and removes the paper dust, may be provided so as to project from the hole 26. In this case, the scraper is preferably made of a flexible thin plastic material or the like so as not to be a load for transporting the ticket paper 2. Further, since the paper dust is positively removed by the scraper, instead of the curved paper guide 25, a paper guide for guiding the leading end of the ticket paper 2 passing through the cutter roller 14 to the paper nipping position E of the feed roller B is provided. Just do it.

Although the ticket processing apparatus 1 for handling airline tickets and the like has been described as an example in the present embodiment and the modification, as long as it is an apparatus for handling a medium having perforations in the direction orthogonal to the medium transport direction, It is not limited to the ticket processing device 1.

[0048]

As described in detail above, the present invention provides
Between the first feed roller and the second feed roller, a rotatable medium cutter roller having a shape in which the diameter increases from the end portion to the central portion is provided in the medium handling device to feed the continuous medium to the first feed roller. When the controller detects that the perforations to be cut off come into contact with the outer peripheral surface of the central portion of the cutter roller while being nipped and conveyed by the roller and the second feed roller,
A drive transmission unit causes a rotational speed difference between the first feed roller and the second feed roller to separate the continuous medium at the perforations, thereby providing an actuator when the ticket paper is separated at the perforations. It is not necessary to operate the cutter roller, and it is not necessary to make fine adjustments in the alignment operation between the separation position and the perforation. As a result, the structure of the cutter unit and the control of medium conveyance are simplified.
