Description

  Embodiments described herein relate generally to a card processing device.

  In the station service room, an IC card processing device for performing predetermined processing on a boarding ticket formed from a ticket medium such as an IC card is installed. Examples of the predetermined process include a process of inputting or rewriting the ticket information on the IC chip, and a process of printing information such as a possible section on the surface of the ticket. The IC card processing apparatus that performs these processes includes an IC processing unit that performs processing on the IC chip, and a printing unit that prints on the surface of the boarding ticket.

  The printing unit includes a print head and a support mechanism that supports the print head. The support mechanism supports the print head so as to be movable between a position for performing a process of printing on the boarding ticket and a position for retracting from the boarding ticket.

  As this support mechanism, a support mechanism that supports the print head so as to be swingable about a rotation axis is known. In the support mechanism that supports the print head so as to be able to swing, the movement path along which the print head moves becomes long because it has an arc shape connecting the position where the printing process is performed and the position where the print head is retracted. For this reason, the support mechanism that supports the print head in a swingable manner requires a large installation space in the housing of the IC card processing apparatus.

  In addition, the print head is required to be in a posture where printing can be satisfactorily performed at a position where the printing process is performed. The posture in which printing can be performed satisfactorily is a posture determined by the shape of the print head or the like. For example, the contact surface that contacts the surface of the ticket in the print head is parallel to the surface of the ticket. It is posture.

  However, as the print head swings around the rotation axis, the posture of the print head always changes during the swing. For this reason, the support mechanism that supports the print head so that the print head can be swung is provided with high accuracy so that the print head can be printed in a position in which the print head is in a position to perform the printing process. It must be able to be positioned.

  On the other hand, as a support mechanism, a support mechanism that supports a print head so as to be movable in a direction orthogonal to the surface of a ticket is known. In this support mechanism, it is possible to move the print head between a position where the printing process is performed and a position where the print head is retracted while maintaining a posture in which printing is good with respect to the ticket. In addition, since the support mechanism can move the print head between the position where the printing process is performed and the position where the print head is retracted, the installation space can be made compact. Such a support mechanism is required to move the print head smoothly.

The support frame 32 is shown in FIG. 2 with respect to the position where the print head pressing device 171 can press the print head fixing portion 80 and the erasing head pressing device 172 can press the erasing head fixing portion 100. 5, the print head fixing unit 80 and the erasing head fixing unit 100 are formed so as to be rotatable between rotation positions that enable replacement work.

  In the state where the support frame 32 is in the rotation position shown in FIG. 5, the print head fixing unit 80 and the erasing head fixing unit 100 are moved upward by moving the print head fixing unit 80 and the erasing head fixing unit 100 upward. Can be separated from the head guide mechanisms 90 and 110. Further, the print head fixing unit 80 and the erasing head fixing unit 100 can be assembled to the head guide mechanisms 90 and 110.

  A part of the pressing devices 171 and 172 is shown in FIGS. First, the erasing head pressing device 172 will be described. The erasing head pressing device 172 has a second transmission mechanism 174 that converts the displacement of the second solenoid 173 and the second solenoid 173 into a displacement in the vertical direction V and transmits the displacement to the erasing head fixing unit 100.

  The second solenoid 173 has a main body 175 and a drive shaft portion 176 that is driven by the main body 175. The main body 175 is fixed to the support frame 32 at a position above the first block 81, for example.

  A part of the drive shaft portion 176 is disposed in the main body 175 and the remaining portion is disposed rearward with respect to the main body 175. The drive shaft portion 176 is supported by the main body 175 so as to be movable in the front-rear direction F. The drive shaft portion 176 is driven between a position where it is drawn into the main body 175 and a position where it exits from the main body 175 by energizing the coil in the main body 175. In FIG. 2, the second solenoid 173 is not driven, and the drive shaft portion 176 is not drawn into the main body 175.

  The second transmission mechanism 174 includes a third pressing member 177 that can press the third block 101, a fourth pressing member 178 that can press the fourth block 102, and the third pressing member 177 and the second pressing member 177. The rotating shaft 179 is fixed to the four pressing members 178.

  As shown in FIG. 2, the third pressing member 177 is disposed above the third block 101. The third pressing member 177 is formed in a plate shape whose planar shape is L-shaped, for example. One end of the third pressing member 177 is provided with a bearing 177 a that is an example of a contact portion that can contact the upper surface 101 a of the third block 101. The bearing 177a is supported by the third pressing member 177 so as to be rotatable around a rotation axis parallel to the width direction W.

  The other end of the third pressing member 177 is connected to the drive shaft 176 of the second solenoid 173. In the present embodiment, the other end portion of the third pressing member 177 is connected to the drive shaft portion 176 via the coil spring 200.

  As shown in FIG. 2, the fourth pressing member 178 is disposed above the fourth block 102. The fourth pressing member 178 is formed in a plate shape. A bearing 178 a that is an example of a contact portion that can contact the upper surface 102 a of the fourth block 102 is provided at an end portion of the fourth pressing member 17. The bearing 178a is supported by the fourth pressing member 178 so as to be rotatable about a rotation axis parallel to the width direction W.

  When the drive shaft portion 176 is pulled into the main body 175, the coil spring 200 is extended by being pulled. The pressing force by the bearings 177 a and 178 a is determined by the spring constant of the coil spring 200. That is, the coil spring 200 is formed so that the pressing force by the bearings 177a and 178a becomes a desired pressing force.

  For example, both ends of the rotation shaft 179 are rotatably supported by the frame 30. For this reason, when the rotating shaft 179 rotates, the third pressing member 177 and the fourth pressing member 178 fixed to the rotating shaft 179 rotate integrally around the axis of the rotating shaft 179.

  The rotating shaft of the bearing 177a supported by the third pressing member 177 and the rotating shaft of the bearing 178a supported by the fourth pressing member 178 are arranged coaxially. For this reason, when the bearing 177a contacts the upper surface 101a of the third block 101 due to the rotation of the rotating shaft 179, the bearing 178a contacts the upper surface 102a of the fourth block 102 at the same time.

  In a state in which the drive shaft portion 176 of the second solenoid 173 is not retracted, that is, in a state in which the drive shaft portion 176 projects rearward from the main body 175 as shown in FIG. 2, the third pressing member 177 moves the third block 101. The fourth pressing member 178 does not press and does not press the fourth block 102.

  When the third pressing member 177 is pulled by the second solenoid 173, the third pressing member 177 rotates around the rotation shaft 179. With this rotation, the rotating shaft 179 and the fourth pressing member 178 rotate integrally. By this rotation, the bearing 177a presses the upper surface 101a of the third block 101 downward, and simultaneously, the bearing 178a presses the upper surface 102a of the fourth block 102 downward, and the erasing head 62 performs processing. It is moved to position P1.

  A part of the print head pressing device 171 is shown in the drawing, but the configuration may be the same as that of the second solenoid 173, for example. In this embodiment, the print head pressing device 171 includes a first solenoid and a first transmission mechanism 180 that converts the displacement of the first solenoid into a displacement in the vertical direction V and transmits the displacement to the print head fixing unit 80. ing.

  For example, the first solenoid is fixed to the support frame 32 at a position above the fourth block 102. The first solenoid may be the same as the second solenoid 173. A part of the drive shaft portion of the first solenoid is disposed in the main body, and the remaining portion is disposed in front of the main body portion. The drive shaft portion is formed to be movable in the front-rear direction F with respect to the main body.

  The first transmission mechanism 180 includes a first pressing member 181 that can press the first block 81, a second pressing member 182 that can press the second block 82, and the first pressing member 181 and the first pressing member 181. The rotating shaft 183 is fixed to the second pressing member 182.

  The first pressing member 181 is disposed above the first block 81. For example, the first pressing member 181 is the same as the fourth pressing member 178. At the end of the first pressing member 181, a bearing 181 a that is an example of a contact portion that can contact the upper surface 81 a of the first block 81 is provided. The bearing 181a is supported by the first pressing member 181 so as to be rotatable around a rotation axis parallel to the width direction W.

  The second pressing member 182 is disposed above the second block 82. The second pressing member 182 is the same as the third pressing member 177, for example. One end of the second pressing member 182 is provided with a bearing 182 a that is an example of a contact portion that can contact the upper surface 82 a of the second block 82. The bearing 182a is supported by the second pressing member 182 so as to be rotatable around a rotation axis parallel to the width direction W.

  The other end of the second pressing member 182 is connected to the drive shaft of the first solenoid. In the present embodiment, the other end portion of the second pressing member 182 is connected to the drive shaft portion via the coil spring 200.

  The coil spring 200 extends by being pulled when the drive shaft portion is pulled into the main body. The pressing force by the bearings 181 a and 182 a is determined by the spring constant of the coil spring 200. That is, the coil spring 200 is formed so that the pressing force by the bearings 181a and 182a becomes a desired pressing force.

  The rotation shaft 183 is rotatably supported by the support frame 32. For this reason, when the rotating shaft 183 rotates, the first pressing member 181 and the second pressing member 182 fixed to the rotating shaft 183 rotate integrally.

  The rotating shaft of the bearing 181a supported by the first pressing member 181 and the rotating shaft of the bearing 182a supported by the second pressing member 182 are arranged on a coaxial line. For this reason, when the bearing 181 a comes into contact with the upper surface 81 a of the first block 81 due to the rotation of the rotating shaft 183, the bearing 182 a comes into contact with the upper surface 82 a of the second block 82 at the same time.

  In a state where the drive shaft portion of the first solenoid is not retracted, the first pressing member 181 does not press the first block 81, and the second pressing member 182 presses the second block 82. do not do.

  When the second pressing member 182 is pulled by the first solenoid, the second pressing member 182 rotates around the rotation shaft 183. And with this rotation, the rotating shaft 183 and the first pressing member 181 rotate integrally. By this rotation, the bearing 181a presses the upper surface 81a of the first block 81 downward. At the same time, the bearing 182a presses the upper surface 82a of the second block 82 downward, and the print head fixing unit 80 performs processing. It is moved to the application position P1.

  Next, the operation of the ticket issuing machine 10 will be described. First, the operation of creating the boarding ticket 5 from the ticket medium 1 will be described. The processing unit 50 is driven by an instruction from the control device or an instruction from another device connected to the ticket issuing machine 10.

  Specifically, the ticket medium 1 in the hopper 40 is fed out of the hopper 40 by the feeding device 51. Next, the transport device 52 is driven. The transport device 52 transports the ticket medium 1 fed out of the hopper 40 to a predetermined position where processing is performed by the IC processing unit 53.

  When the ticket medium 1 is transported to a predetermined position where the IC processing unit 53 performs processing, the driving of the transport device 52 is stopped. When the driving of the transport device 52 is stopped, the ticket medium 1 stops at the predetermined position described above. When the conveyance of the ticket medium 1 is stopped, the IC processing unit 53 inputs various information to the IC chip 2 of the ticket medium 1. When the processing in the IC processing unit 53 is completed, the transport device 52 is driven, and the ticket medium 1 is transported to a predetermined position where the printing process is performed by the print head 61 in the printing unit 60.

  When the ticket medium 1 is transported to the print head platen roller 63 at a predetermined position where the print processing by the print head 61 is performed, the transport device 52 is stopped. When the transport device 52 is stopped, the ticket medium 1 stops at the predetermined position.

  When the conveyance of the ticket medium 1 is stopped, the printing process is performed on the surface 3 of the ticket medium 1 by the print head 61. Specifically, first, the first solenoid is driven. When the first solenoid is driven, the drive shaft portion pulls the second pressing member 182. By pulling the second pressing member 182, the second pressing member 182 rotates around the axis of the rotation shaft 183. Further, along with this rotation, the rotation shaft 183 and the second pressing member 182 also rotate together.

  As the pressing members 181 and 182 rotate, the bearing 181a presses the upper surface 81a of the first block 81 downward, and at the same time, the bearing 182a presses the upper surface 82a of the second block 82 downward. The pressing force by the bearings 181a and 182a becomes a desired pressing force by the coil spring 200.

  As described above, the print head pressing device 171 moves down the print head fixing portion 80 due to the elastic force of the first springs 151 a and 151 b, and moves the print head 61 to the surface 3 of the ticket medium 1. Move until it touches. That is, as shown in FIG. 6, the print head 61 is moved from the retracted position P2 to the position P1 where the printing process is performed. In FIG. 6, the erasing head fixing unit 100 is also moved to the position P1 where processing is performed. When only the printing process is performed, only the print head fixing unit 80 moves to the position P1 as shown in FIG. 6, and the erasing head fixing unit 100 stands by at the position P2 as shown in FIG.

  When the first solenoid is driven and the drive shaft is pulled into the main body, the print head 61 moves downward from the retracted position P2 in accordance with the pull-in amount. In the present embodiment, the pull-in amount of the drive shaft portion into the main body when the first solenoid is driven is set to an amount that allows the print head 61 to sufficiently contact the surface 3 of the ticket medium 1. .

  Specifically, even after the print head 61 moves downward and comes into contact with the surface 3 of the ticket medium 1, the amount of the drive shaft portion is slightly pulled into the main body. However, the coil spring 200 that connects the drive shaft portion and the second pressing member 182 extends, so that even if the drive shaft portion is drawn into the main body after the print head 61 comes into contact, the second amount corresponding to this pull-in amount. Even if the pressing member 182 is pulled, this tensile force is absorbed by the extension of the coil spring 200. For this reason, the print head 61 is prevented from being excessively pressed against the surface 3, and the state where the print head 61 is pressed against the surface 3 by the elastic force of the coil spring 200 is maintained.

  When the printing process by the print head 61 is completed, the ticket medium 1 becomes the boarding ticket 5. When the printing process is completed, the power supply to the first solenoid is stopped. When the energization of the first solenoid is stopped, the pressing force by the print head pressing device 171 is released, so that the print head fixing unit 80 is caused by the elastic force of the first spring 151a and the second spring 151b. It is pushed up to the retracted position P2.

  When the print head 61 is moved to the retracted position P <b> 2, the transport device 52 is driven and the boarding ticket 5 is transported to the opening 21.

  Next, an operation for performing a process of rewriting information on the existing ticket 5 will be described. When the existing ticket 5 is inserted through the opening 21, the transport device 52 is driven. For example, the ticket 5 is first subjected to processing for rewriting information in the IC chip 2.

  The transport device 52 transports the ticket 5 to a predetermined position where the IC processing unit 53 performs processing. When the boarding ticket 5 is transported to the predetermined position, the driving of the transport device 52 is stopped. When the driving of the transport device 52 is stopped, the boarding ticket 5 stops at the predetermined position.

  When the boarding ticket 5 is stopped at a predetermined position where the processing is performed by the IC processing section 53, the IC processing section 53 rewrites the information in the IC chip 2 of the boarding ticket 5 with new information. When the processing in the IC processing unit 53 is completed, the processing is performed in the printing unit 60 next.

  The transport device 52 transports the boarding ticket 5 to a predetermined position where the erasing process is performed by the erasing head 62 of the printing unit 60. When the boarding ticket 5 is transported to the predetermined position, the driving of the transport device 52 is stopped. When the driving of the transport device 52 is stopped, the boarding ticket 5 stops at the predetermined position.

  When the boarding ticket 5 is stopped at a predetermined position where the erasing process is performed by the erasing head 62, that is, when the boarding ticket 5 is placed on the erasing head platen roller 64, the erasing head 62 makes the boarding ticket. An erasing process for erasing characters printed on the front surface 3 of 5 is performed. Specifically, first, the second solenoid 173 is driven. When the second solenoid 173 is driven, the drive shaft portion 176 pulls the third pressing member 177.

  By pulling the third pressing member 177, the third pressing member 177 rotates around the axis of the rotation shaft 179. Further, along with this rotation, the rotation shaft 179 and the fourth pressing member 178 also rotate together.

  As the pressing members 178 and 178 rotate, the bearing 177a presses the upper surface 101a of the third block 101 downward, and at the same time, the bearing 178a presses the upper surface 102a of the fourth block 102 downward.

  As described above, the erasing head pressing device 172 moves downward on the erasing head fixing portion 100 due to the elastic force of the third springs 152a and 152b, and moves the erasing head 62 to the surface 3 of the ticket 5. Move until it touches. That is, as shown in FIG. 6, the erasing head 62 is moved from the retracted position P2 to the position P1 where the erasing process is performed. In FIG. 6, the print head fixing unit 80 is also moved to the position P1 where processing is performed. When only the erasing process is performed, only the erasing head fixing unit 100 moves to the position P1 as shown in FIG. 6, and the print head fixing unit 80 stands by at the position P2 as shown in FIG.

  When the second solenoid 173 is driven and the drive shaft portion 176 is pulled into the main body 175, the erasing head 62 moves downward from the retracted position P2 in accordance with the pull-in amount. In this embodiment, when the second solenoid 173 is driven, the pull-in amount of the drive shaft portion 176 into the main body 175 is set to an amount that allows the erasing head 62 to sufficiently contact the surface 3 of the ticket 5. Has been.

  Specifically, even after the erasing head 62 moves downward and contacts the surface 3 of the ticket 5, the drive shaft portion 176 is slightly pulled into the main body 175. However, the extension of the coil spring 200 that connects the drive shaft portion 176 and the fourth pressing member 178 causes the drive shaft portion 176 to be drawn into the main body 175 after the erasing head 62 contacts the surface 3, and this pull-in amount Accordingly, even if the fourth pressing member 178 is pulled, this pulling force is absorbed by the coil spring 200 extending. Therefore, the erasing head 62 is prevented from being excessively pressed against the surface 3, and the state where the erasing head 62 is pressed against the surface 3 by a desired pressing force is maintained by the elastic force of the coil spring 200.

  When the erasing process is completed, the power supply to the second solenoid 173 is stopped. When the energization of the second solenoid 173 is stopped, the pressing force to the erasing head fixing unit 100 by the erasing head pressing device 172 is released, so that the erasing head fixing unit 100 includes the third spring 152a and the fourth spring 152a. The spring 152b is pushed up to the retracted position P2 by the elastic force of the spring 152b.

  When the erasing head 62 is moved to the retracted position P <b> 2, the transport device 52 is driven and the boarding ticket 5 is transported by the print head 61 to a predetermined position where the printing process is performed. When the boarding ticket 5 is transported to a predetermined position where the printing process is performed by the print head 61, the driving of the transport device 52 is stopped and the boarding ticket 5 is stopped at the predetermined position.

  When the boarding ticket 5 is stopped, the print head pressing device 171 and the print head 61 are driven as described above, and the printing process is performed. When the printing process is completed, the transport device 52 is driven and the boarding ticket 5 is transported to the opening 21.

  Next, replacement work of the print head 61 and the erasing head 62 will be described. When the print head 61 is replaced, the entire print head fixing unit 80 is replaced. First, as shown in FIG. 5, the support frame 32 is rotated. Next, the fixing member 160 is removed. Next, the first shaft 91 is removed from the linear ball bearing 84 and the second shaft 92 is removed from the communication hole 85 by moving the print head fixing portion 80 upward. When the shafts 91 and 92 are removed, the separation operation of the print head fixing unit 80 from the print head guide mechanism 90 is completed.

  Next, the new print head fixing unit 80 is assembled to the print head guide mechanism 90. Specifically, the first shaft 91 is inserted into the linear ball bearing 84 of the first block 81, and the second shaft 92 is inserted into the communication hole 85 of the second block 82.

  When the assembly operation of the print head fixing unit 80 to the print head guide mechanism 90 is completed, the fixing member 160 is fixed to the shafts 91 and 92. The replacement operation of the erasing head 62 is performed in the same manner as the replacement operation of the print head 61.

  The ticket issuing machine 10 of this embodiment includes a print head fixing unit 80 to which the print head 61 is fixed, and a first shaft 91 and a second shaft 92 that guide the vertical movement of the print head fixing unit 80. doing. The print head fixing portion 80 includes a linear ball bearing 84 that supports the first shaft 91, and a communication hole 85 in which the second shaft 92 is disposed. Further, in the print head fixing unit 80, the print head 61 is fixed in a good posture with respect to the surface 3 of the ticket medium 1 and the surface 3 of the ticket 5.

  For this reason, the print head 61 moves along the linear movement path that is the shortest distance between the position P1 where the printing process is performed and the position P2 where the print head 61 is retracted, while maintaining a posture in which good printing on the surface 3 is possible. Will come to be. For this reason, since the printing part 60 can be formed compactly, the installation space can be saved.

  Furthermore, since the first shaft 91 is supported by the linear ball bearing 84, the print head fixing portion 80 is smoothly moved. Furthermore, even if either one or both of the first shaft 91 and the second shaft 92 is slightly inclined with respect to the vertical direction V, the gap between the second shaft 92 and the communication hole 85 is used. Thus, the smooth movement of the print head fixing unit 80 is ensured.

  In particular, the communication hole 85 is formed in the shape of a long hole whose cross-sectional shape perpendicular to the axis thereof is long in the width direction W, so that the print head 61 may print errors outside the printing range of the ticket medium 1 and the ticket 5. Printing can be prevented from occurring. This point will be described.

  The ticket medium 1 and the ticket 5 have a shape that is long in the width direction with respect to the front-rear direction, the front-rear direction is parallel to the front-rear direction of the transport path L, and the width direction is the width direction of the transport path L. It is placed and transported on the placement surface PV of the transport path L in a parallel posture.

  The information printed on the surface 3 of the railroad ticket 5 is the name of the boarding section or the owner, and may be printed long in the width direction of the surface 3. For this reason, the printing range is set relatively wide in the width direction of the ticket 5. However, the length in the front-rear direction of the printing range is relatively short in order to avoid interference with patterns around the surface 3 and the like.

  For this reason, by forming the communication hole 85 into a long hole shape that is long in the width direction, it is possible to absorb a slight inclination with respect to the vertical direction V of the shafts 91 and 92 as described above, and the print head 61 when performing the printing process. The positional deviation with respect to the ticket 5 can be within an allowable range. That is, erroneous printing by the print head 61 can be prevented.

  Further, since the print head fixing portion 80 is supported by the shafts 91 and 92, when replacing the print head fixing portion 80, the print head fixing portion 80 is pulled upward, and the linear ball bearing of the new print head fixing portion 80 is obtained. 84 and the shafts 91 and 92 need only be inserted into the communication hole 85. For this reason, since the exchange work of the print head fixing | fixed part 80 can be performed easily, work efficiency can be improved.

  Further, by fixing the print head 61 to the print head fixing unit 80, the posture of the print head 61 with respect to the transport path L is always maintained in a posture in which the printing process can be performed satisfactorily. For this reason, even if the print head fixing unit 80 is replaced, it is not necessary to adjust the posture of the print head 61 each time, so that the work efficiency of the replacement operation of the print head fixing unit 80 can be improved.

  The ticket issuing machine 10 includes an erasing head fixing unit 100 to which the erasing head 62 is fixed, and a third shaft 111 and a fourth shaft 112 that guide the movement of the erasing head fixing unit 100 in the vertical direction V. ing. The erasing head fixing unit 100 includes a linear ball bearing 104 that supports the third shaft 111, and a communication hole 105 in which the fourth shaft 112 is disposed. Further, in the erasing head fixing unit 100, the erasing head 62 is fixed in a good posture with respect to the surface 3 of the ticket 5.

  For this reason, the erasing head 62 maintains a posture capable of performing a favorable erasing process on the surface 3, and forms a linear movement path that is the shortest distance between the processing position P <b> 1 and the retreat position P <b> 2. Will be moved along. For this reason, since the printing part 60 can be formed compactly, the installation space can be saved.

  Further, since the third shaft 111 is supported by the linear ball bearing 104, the erasing head fixing unit 100 is smoothly moved. Furthermore, even if either one or both of the third shaft 111 and the fourth shaft 112 is slightly inclined with respect to the vertical direction V, the gap between the fourth shaft 112 and the communication hole 105 is used. Thus, smooth movement of the erasing head fixing unit 100 is ensured.

  In particular, the communication hole 105 is formed in a long hole shape that is long in the width direction W, thereby ensuring smooth movement of the erasing head fixing unit 100 while keeping the positional deviation of the erasing head 62 with respect to the ticket 5 within an allowable range. be able to.

Further, since the erasing head fixing unit 100 is supported by the shafts 111 and 112, when the erasing head fixing unit 100 is replaced, the erasing head fixing unit 100 is pulled upward and a linear ball bearing of the new erasing head fixing unit 100 is used. It is only necessary to insert the shafts 111 and 112 into the 104 and the communication hole 105. For this reason, the replacement work of the erasing head fixing unit 100 can be easily performed, so that the work efficiency can be improved.
Further, the erasing head 62 is fixed to the erasing head fixing unit 100, so that the posture of the erasing head 62 with respect to the transport path L is always maintained in a posture where the erasing process can be performed satisfactorily. For this reason, even if the erasing head fixing unit 100 is replaced, it is not necessary to adjust the posture of the erasing head 62 each time, so that the work efficiency of the replacement operation of the erasing head fixing unit 100 can be improved.

  The print head fixing unit 80 includes a first block 81, a second block 82, and a first connecting unit 83. Therefore, for example, the first block 81 and the second block 82 of the replaced print head fixing unit 80 can be reused. As described above, since the print head fixing unit 80 includes a plurality of components, the print head fixing unit 80 having a complicated shape can be easily formed, and the components can be reused.

  Similarly, in the erasing head fixing portion 100, the erasing head fixing portion 100 having a complicated shape can be easily formed, and its components can be reused.

  Further, by having the moving device 150, the print head fixing unit 80 and the erasing head fixing unit 100 can be easily moved.

  In addition, the moving device 150 urges the print head fixing portion 80 toward the retracted position P2, and the erasing head that urges the erasing head fixing portion 100 toward the retracting position P2. The configuration of the moving device 150 can be simplified by including the urging unit 152 and the pressing device 170 that presses the print head fixing unit 80 and the erasing head fixing unit 100.

  In the present embodiment, linear ball bearings 84 and 104 are used as bearing members that support the shafts 91 and 111. As another example, a slide bush may be used as the bearing member.

  The print head fixing unit 80 is urged to the retracted position P2 by the print head urging unit 151, and compression coil springs 151a and 151b are used as the print head urging unit 151. As another example, a leaf spring may be used for the print head urging unit 151. Similarly, a plate spring may be used as the erasing head urging unit 152 in the erasing head fixing unit 100.

  Further, the print head urging unit 151 is used to maintain the print head fixing unit 80 at the retracted position P2. As another example, the ticket issuing machine 10 is configured to maintain the print head fixing unit 80 at the retracted position P2 by another device such as a link mechanism using a solenoid instead of the print head urging unit 151. May be. Similarly, the ticket issuing machine 10 may be configured to maintain the erasing head fixing unit 100 at the retracted position P2 by another device such as a link mechanism using a solenoid instead of the erasing head urging unit 152.
