Description

  The present invention relates to a medium supply device and a ticket issuing device, and more particularly to a medium supply device that supplies a medium and a ticket issuing device that issues a ticket.

  With the progress of automatic processing technology in recent years, ticket issuing devices that automatically issue tickets are used for issuing various tickets such as boarding passes and boarding passes. In recent years, in order to automatically process such tickets, in addition to printing, readable data such as magnetic data is recorded on the tickets.

  In response to this request, the ticket issuing device uses a ticket medium having a magnetic data area, and data (for example, for a boarding pass, boarding date, boarding flight name, boarding time, seat number, passenger name) Etc.), and these are printed so as to be visible. In recent years, there is a demand for handling a plurality of types of tickets (for example, each airline) (for example, see Patent Document 1) with this ticket issuing device.

FIG. 13 is a diagram showing a part of the internal structure of a conventional ticket issuing device.
As shown in FIG. 13, a plurality of different types of fanfold continuous paper (medium) 81, 82, 83 are installed on a floor or the like away from the ticket issuing device 90.

The ticket issuing device 90 includes a medium supply mechanism 91, a cutter 92, a magnetic head 93, and a printing unit 94.
The medium supply mechanism 91 has rollers (not shown) for holding the fanfold continuous papers 81, 82, and 83 and transporting them to the cutter 92. The medium supply mechanism 91 supplies the medium by driving the rollers by independent motors, or by switching a roller that transmits driving via a clutch or the like by one motor.

Then, one of the appropriate fanfold continuous sheets 81, 82, and 83 is selected according to the type of ticket to be issued, and conveyed to the cutter 92.
The cutter 92 cuts the conveyed fanfold continuous paper into a single ticket.

The magnetic head 93 performs magnetic recording and reading of the cut ticket.
The printing unit 94 prints predetermined information on the ticket. For example, for an air ticket, the airline, boarding date, boarding flight name, boarding gate, boarding time, seat number, etc. are printed.

The printed ticket is discharged from the ticket issuing device 90.
JP 2005-346196 A

  The medium supply mechanism 91 needs to continue the state in which the other medium that is not supplied to the ticket issuing device 90 among the held fanfold continuous sheets 81, 82, and 83 is held by the transport roller. is there.

  However, the held fanfold continuous paper 81, 82, 83 moves due to external vibration, the own weight of the fanfold continuous paper 81, 82, 83, interference with the other medium supplied, etc. The medium supply mechanism 91 may fall off. For this reason, in order to prevent this, it is necessary to fix the rotation of the conveying roller.

  As a fixing method, a dedicated drive motor may be provided for each roller, and this may be locked, or the roller itself may be locked by some method, but the mechanism is complicated. There is a problem that the number of parts increases and costs increase.

  SUMMARY An advantage of some aspects of the invention is that it provides a medium supply device and a ticket issuing device capable of easily holding a medium.

In order to achieve the above object, a medium supply device for supplying a ticket medium is provided. This medium supply device has a pair of rollers and a rotation suppression unit.
The pair of rollers sandwich and support the ticket medium.

The rotation suppressing portion has a contact portion that contacts the end surface of at least one end of at least one of the shafts that respectively support the pair of rollers, and the friction force generated between the contact portion and the shaft Suppresses axial rotation of the shaft.

  According to such a medium supply device, the axial rotation of the shaft is suppressed by the frictional force generated between the contact portion of the rotation suppressing portion and the shaft.

According to the medium supply device of the disclosure, since the rotation is restricted by a biasing in the axial direction of the shaft, the pair of rollers can easily support the ticket medium.

Hereinafter, embodiments will be described in detail with reference to the drawings.
1 and 2 are diagrams illustrating an outline of a ticket issuing device according to an embodiment.
As shown in FIG. 1, the ticket issuing device 1 is installed on a hollow base 10.

  In the base 10, hoppers 53 and 54 that store fanfold continuous paper (folding continuous paper) 51 and 52 that are tickets (for example, a boarding ticket, an air ticket, etc.) are installed. A large number of perforations are formed on the fanfold continuous paper 51 and 52 at predetermined intervals.

These fanfold continuous papers 51 and 52 are guided to the back side of the ticket issuing device 1 through guide mechanisms 61 and 62 each including a tension roller.
In addition, the fanfold continuous paper 51 and 52 may be directly guided to the back side of the ticket issuing device 1.

  As shown in FIG. 2, on the front surface of the ticket issuing device 1, an indicator group 2 that displays the operation state of the ticket issuing device 1, an input key group 3 for operating the ticket issuing device 1, and the issued ticket Is provided with a discharge stacker 4 from which the ticket is discharged and a ticket insertion slot 5 into which a ticket is inserted.

  The medium supply unit 11 selects the fanfold continuous paper 51 or the fanfold continuous paper 52 according to an instruction from a control unit (not shown), and supplies the selected paper to the cutter 12. Although this supply speed | rate is not specifically limited, For example, it is about 1 m / s.

  The cutter 12 cuts and separates one of the fanfold continuous paper 51 or the fanfold continuous paper 52 supplied from the medium supply unit 11 at the perforations described above to form one ticket.

Since the ticket is a kind of cash voucher, each ticket is recorded with a number for managing the ticket for the purpose of preventing forgery.
The ring transport unit 13 includes a magnetic head 131, a cylindrical ring 132, and rollers 133, 134, and 135 provided to surround the ring 132.

  The magnetic head 131 magnetically records data (authorization number or the like) on a ticket located at the bottom, reads the recorded data, and collates whether the written data matches the read data. .

  The rollers 133, 134, and 135 support (clamp) a ticket by sandwiching a ticket between the ring 132 and a belt wound around the outer periphery of the rollers 133, 134, and 135, respectively. The ticket is moved along the outer periphery of the ring 132 by driving a predetermined roller in accordance with an instruction from the control unit.

  The thermal transfer printing head 14 prints the airline, boarding date, boarding flight name, boarding gate, boarding time, seat number, etc. on the transported ticket based on the collation result of the magnetic head 131. Specifically, if the data match as a result of the collation, printing is performed and the sheet is conveyed to the gate 15. On the other hand, if the data do not match, the data is conveyed to the gate 15 without printing.

  The gate 15 discharges the ticket 100 printed by the thermal transfer print head 14 to the discharge stacker 4 among the transported tickets. On the other hand, the ticket 101 that has not been printed by the thermal transfer print head 14 is accommodated in the reject stacker 16.

  According to such a ticket issuing device 1, the ticket cut by the cutter 12 is guided to the ring transport unit 13. Then, the roller 133 of the ring conveyance unit 13 is driven, and the ticket is sandwiched between the ring 132 and the belt wound around the roller 133. The sandwiched ticket is moved along the outer periphery of the ring 132 and positioned at the lower part of the magnetic head 131.

  At this time, data is magnetically recorded on the ticket by the magnetic head 131. Thereafter, the rollers 133 and 134 are driven, the ticket is sandwiched between the ring 132 and the belt wound around the rollers 133 and 134, and the ticket once moves to the right of the magnetic head 131.

  Thereafter, the rollers 133 and 134 are driven, and the ticket is guided to the lower part of the magnetic head 131 again. The magnetic head 131 reads the magnetically recorded data, and checks whether the written data matches the read data. Thereafter, the roller 135 is driven, the ticket is sandwiched between the ring 132 and the belt wound around the roller 135, and the ticket is conveyed to the thermal transfer print head 14.

  After that, the airline, boarding date, boarding flight name, boarding gate, boarding time, seat number, etc. are printed on the transported ticket by the thermal transfer print head 14 based on the collation result of the magnetic head 131 and transported to the gate 15. The

  The tickets printed by the thermal transfer print head 14 are discharged to the discharge stacker 4 by the gate 15. On the other hand, tickets that are not printed by the thermal transfer print head 14 are accommodated in the reject stacker 16.

Next, the configuration of the medium supply unit 11 will be described in detail.
FIG. 4 is a perspective view showing the configuration of the medium supply unit.
The medium supply unit 11 includes frames 111 a and 111 b provided on the left and right sides, ticket clamping units 112 and 113, a motor 114, a clutch mechanism unit 115, and a rotation suppression unit 116.

  The frames 111a and 111b serve as a guide mechanism that makes the supply direction of the fanfold continuous paper 51 and 52 to the cutter 12 constant. The interval between the frames 111a and 111b is slightly wider than the width of the fanfold continuous paper 51 and 52.

  The ticket holding unit 112 includes shafts 112a and 112b supported by the frames 111a and 111b, a driving roller 112c attached to the shaft 112a, and a pinch roller 112d attached to the shaft 112b. The fanfold continuous paper 51 inserted from the lower part in FIG. 4 is sandwiched between the drive roller 112c and the pinch roller 112d.

  The ticket holding unit 113 includes shafts 113a and 113b supported by the frames 111a and 111b, a driving roller 113c provided so as to be able to idle around the shaft 113a, and a pinch roller 113d attached to the shaft 113b. Yes. The fanfold continuous paper 52 inserted from the lower part in FIG. 4 is sandwiched between the drive roller 113c and the pinch roller 113d.

A gear that meshes with a clutch gear (described later) of the clutch mechanism 115 is provided on the left side (the frame 111b side) of the drive roller 113c.
The motor 114 is attached to the frame 111b and selectively drives (rotates) the driving roller 112c or the driving roller 113c. In addition, although this rotation speed is not specifically limited, For example, it is about 960 rpm.

  A belt driving roller 114a is attached to the motor 114, and the driving force of the motor 114 is transmitted to the timing belt 117 through the belt driving roller 114a. The driving force is transmitted to the clutch mechanism 115 by the rotation (circulation drive) of the timing belt 117.

The clutch mechanism 115 switches between the driving roller 112c to be driven and the driving roller 113c in accordance with a control signal from the control unit.
The rotation suppression unit 116 is attached to the frame 111a and urges the drive roller 112c in the axial direction to suppress rotation of the shaft 112a to which the drive roller 112c is attached.

5 and 6 are front views showing the configuration of the drive mechanism of the medium supply unit.
In the following description, the right side in FIG. 5 is referred to as “right”, and the left side is referred to as “left”.
The clutch mechanism 115 includes a clutch gear 115a attached to the shaft 113a, a clutch 115c attached to the shaft 115b, meshing with the clutch gear 115a and switching between the driving roller 112c and the driving roller 113c to be driven, and the shaft 113a. And a gear portion 115d for driving the driving roller 112c.

  The clutch gear portion 115a rotates in direct connection with the shaft 113a. The clutch gear portion 115a has a gear 1151a that meshes with the gear portion 115d and a gear 1152a that meshes with the gear of the drive roller 113c.

  The clutch 115c is provided so as to be movable in the left-right direction in FIG. 5 along the shaft 115b. The clutch gear portion 115a moves left and right on the shaft 113a in conjunction with the movement of the clutch 115c in the left-right direction.

  The gear portion 115d is provided so as to be able to idle around the shaft 113a. A gear 1151d that meshes with the gear 1151a is provided at the right end of the gear portion 115d. A gear 1152d that transmits a driving force to the gear 112e is provided at the left end of the gear portion 115d.

  According to such a medium supply unit 11, the driving force of the motor is transmitted to the timing belt 117 by the belt driving roller 114 a attached to the motor 114. The driving force is transmitted to the shaft 113a as the timing belt 117 rotates.

  As shown in FIG. 5, when the clutch 115c is located in the left direction, the gear 1151a of the clutch gear portion 115a meshes with the gear 1151d of the gear portion 115d. In this state, the driving force of the motor 114 is transmitted in the order of the timing belt 117, the shaft 113a, the clutch gear portion 115a, the gear portion 115d, the gear 112e, and the driving roller 112c.

As a result, the drive roller 112c rotates toward the front side in FIG. 5 and the fanfold continuous paper 51 sandwiched between the pinch roller 112d is conveyed to the cutter 12.
At this time, the driving roller 113c to which the driving force of the motor 114 is not transmitted is in a free state. However, since the fanfold continuous paper 52 is inclined at a predetermined angle while being sandwiched between the driving roller 113c and the pinch roller 113d, the driving roller 113c and the pinch roller 113d are not subjected to a considerable external force exceeding its own weight. The stationary state (held state) is maintained by the friction force generated between them. That is, the fanfold continuous paper 52 does not move with respect to the driving roller 113c due to its own weight, and even if a certain amount of swinging or vibration is applied, the fanfold continuous paper 52 is stationary between the driving roller 113c and the pinch roller 113d. To maintain.

  On the other hand, as shown in FIG. 6, when the clutch 115c is positioned in the right direction, the gear 1152a of the clutch gear portion 115a meshes with the gear of the drive roller 113c. In this state, the driving force of the motor 114 is transmitted in the order of the timing belt 117, the shaft 113a, the clutch gear portion 115a, and the driving roller 113c.

  As a result, the driving roller 113c rotates forward in FIG. 6, and the fanfold continuous paper 52 sandwiched between the pinch roller 113d is conveyed to the cutter 12. At this time, the rotation of the drive roller 112c to which no motor drive is transmitted is suppressed by the rotation suppression unit 116. Thereby, it is possible to easily prevent the fanfold continuous paper 51 from falling due to its own weight.

FIG. 7 is a perspective view illustrating the configuration of the rotation suppression unit, and FIG. 8 is a side cross-sectional view illustrating the configuration of the rotation suppression unit.
The rotation suppression unit 116 includes a suppression member 116a, a stopper (contact portion) 116b, and a leaf spring (biasing member) 116c.

  The restraining member 116a is made of, for example, a treated steel plate whose surface is plated. The holding member 116a has a shape that covers the stopper 116b and the leaf spring 116c, and is fixed to the frame 111a with screws (not shown) in a state where the stopper 116b and the leaf spring 116c are disposed inside. In this state, the holding member 116a supports the stopper 116b and the leaf spring 116c so as not to rotate in the rotation direction of the shaft 112a.

  The stopper 116b is made of a resin with relatively high wear resistance, such as polyacetal (POM). The stopper 116b has a substantially rectangular shape and is in contact with the end of the shaft 112a.

  The plate spring 116c is made of stainless steel, for example, and is sandwiched between the stopper 116b and the stopper 116b by the holding member 116a. The leaf spring 116c urges the stopper 116b in the left direction in FIG. 8 by the restoring force of the leaf spring 116c itself. More specifically, the contact surface of the stopper 116b with the shaft 112a is always urged by the action of the leaf spring 116c. The friction force generated between the stopper 116b and the end of the shaft 112a can suppress (brake) the rotation of the shaft 112a without disturbing the conveyance path of the fanfold continuous paper 51 to the cutter 12.

  The biasing force of the stopper 116b against the end of the shaft 112a (the biasing force of the leaf spring 116c against the stopper 116b) is not particularly limited, but is preferably 3.9N to 5.9N, for example. By urging with such an urging force, wear of the stopper 116b can be prevented, and rotation of the shaft 112a can be suppressed for a long period of time.

Further, the rotation suppression force to the shaft 112a can be changed by changing the material of the stopper 116b and the urging force of the leaf spring 116c.
As described above, according to the ticket issuing device 1, the resin stopper 116b is pressed against the side surface of the shaft (drive roller shaft) 112a that rotates at a relatively high speed, and the leaf spring 116c and the pressing member for pressing the resin stopper 116b. 116a was placed.

Accordingly, it is possible to easily suppress the rotation of the driving roller 112c when the driving force is not transmitted and always suppress it with a load as necessary.
Therefore, even when the shaft 112a is disconnected from the drive of the motor 114 by the clutch mechanism 115, the drive roller 112c can be freely rotated without the addition of a complicated lock mechanism or the like. It can be suppressed by the mechanism and the low cost method. Thereby, it is possible to prevent the held fanfold continuous paper 51 from falling.

Next, a ticket issuing apparatus according to the second embodiment will be described.
Hereinafter, the ticket issuing device according to the second embodiment will be described with a focus on differences from the ticket issuing device 1 according to the first embodiment described above, and description of similar matters will be omitted.

The ticket issuing device 1 according to the second embodiment is different from the first embodiment in the configuration of the medium supply unit.
FIG. 9 is a side sectional view showing a medium supply unit according to the second embodiment.

The medium supply unit 11a includes a rotation suppression unit 118.
The rotation suppressing unit 118 further includes an urging force adjusting unit 116d that adjusts the urging force of the leaf spring 116c.

The urging force adjusting portion 116d has a fixing nut 1161d and an adjusting screw 1162d.
Further, a screw hole 1162a is provided at the center of the surface 1161a of the restraining member 116a of the rotation restraining portion 118.

The fixing nut 1161d is fixed to the holding member 116a in a state where the hole is overlapped with the screw hole 1162a.
The adjustment screw 1162d is inserted in the left direction in FIG. 9 by screwing into the fixing nut 1161d, and is inserted through the screw hole 1162a to suppress (press contact) the leaf spring 116c. The biasing force can be easily adjusted by adjusting the insertion distance.

According to the medium supply unit 11a of the second embodiment, the same effect as that of the medium supply unit 11 of the first embodiment can be obtained.
And according to the medium supply part 11a of 2nd Embodiment, the rotation suppression force can be easily adjusted by adjusting biasing force further.

<Application example>
For example, the rotation suppression force can be controlled using the mechanism that can adjust the rotation suppression force described above.

FIG. 10 is a diagram illustrating a hardware function for the ticket issuing device to control the rotation suppression force.
The ticket issuing device 1 includes a central processing unit (CPU) 21, a random access memory (RAM) 22, a read only memory (ROM) 23, and an encoder 24.

The CPU 21 controls the overall operation of the ticket issuing device 1.
The RAM 22 temporarily stores at least a part of application programs to be executed by the CPU 21. The RAM 22 stores various data necessary for processing by the CPU 21. The ROM 23 stores application programs.

The encoder 24 detects the rotation of the shaft 112a.
FIG. 11 is a diagram illustrating functions of the CPU.
The CPU 21 includes an encoder monitoring unit 21a, a medium detecting unit 21b, a motor driving unit 21c, and an urging force adjusting unit 21d.

The encoder monitoring unit 21a acquires a detection signal when the encoder 24 detects the rotation of the shaft 112a.
The medium detection unit 21b includes a sensor that detects whether or not the fanfold continuous paper 52 is sandwiched between the drive roller 112c and the pinch roller 112d.

The motor drive unit 21 c supplies a drive signal to the motor 114.
The urging force adjustment unit 21d adjusts the urging force of the stopper 116b on the shaft 112a according to the detection signal acquired by the encoder monitoring unit 21a, the detection signal of the medium detection unit 21b, and the drive signal of the motor drive unit 21c. Hereinafter, the process of the urging force adjusting unit 21d will be described in detail.

FIG. 12 is a flowchart showing processing of the urging force adjustment unit.
First, the urging force adjusting unit 21d determines whether or not the fanfold continuous paper 52 is sandwiched between the drive roller 112c and the pinch roller 112d based on the detection signal from the medium detection unit 21b (step S1).

If the fanfold continuous paper 52 is not sandwiched between the drive roller 112c and the pinch roller 112d (No in step S1), the process is terminated.
On the other hand, when the fanfold continuous paper 52 is sandwiched between the drive roller 112c and the pinch roller 112d (Yes in step S1), the urging force adjusting unit 21d acquires the detection signal of the encoder 24 from the encoder monitoring unit 21a. (Step S2), it is determined whether or not the shaft 112a is rotating (Step S3).

When the shaft 112a is not rotating (No in Step S3), the process proceeds to Step S1, and the processes after Step S1 are continued.
On the other hand, when the shaft 112a is rotating (Yes in step S3), the urging force adjustment unit 21d acquires a drive signal from the motor drive unit 21c and determines whether the shaft 112a is driven by the motor 114. (Step S4).

  When the shaft 112a is driven (Yes in Step S4), the biasing force adjusting unit 21d releases the bias of the stopper 116b (Step S5). Then, it transfers to step S1 and performs the process after step S1 continuously.

  On the other hand, when the shaft 112a is not driven (No in step S4), the biasing force adjusting unit 21d biases the stopper 116b to the shaft 112a (step S6). Then, it transfers to step S1 and performs the process after step S1 continuously.

This is the end of the description of the processing. Thereby, rotation of the shaft 112a can be suppressed only when necessary.
