Description

  Embodiments discussed herein relate to media processing devices that perform media processing, such as magnetic processing, on media.

  Conventionally, a magnetic reading / writing unit of a passbook printer mounted on an ATM (Automated Teller Machine) device is used for writing information on a magnetic stripe of a passbook, reading read information, etc. (for example, patents) Reference 1 and 2).

  There is a standard in the magnetic writing position of the bankbook, and the position where the magnetism is written is determined by the position where the bankbook is conveyed to the magnetic reading / writing section and stopped. By matching the conveyance reference position and the end of the bankbook, the bankbook can be set so as not to exceed the magnetic writing position standard.

  In the passbook printer installed in the ATM device, when setting the passbook, the transfer reference position is aligned with the end of the passbook, so that it is opposite to the guide member serving as the transfer reference in the transfer path where the magnetic reading / writing unit is arranged. The side guide member is configured to be movable in the passbook width direction. As a structure of the movable guide member, there is a mechanism that presses the bankbook against the guide member on the conveyance reference side using a leaf spring.

  In the medium processing device such as the above-mentioned passbook printer, the magnetic information is read / written to the medium being transported instead of the stationary medium, but the passbook is damaged by weakening the pushing force of the passbook when reading / writing the magnetic information. There has been proposed one for preventing the skew and skew (see Patent Document 1).

Japanese Patent Laid-Open No. 2007-259593 JP 2008-310592 A

  By the way, when performing processing such as reading / writing or printing of magnetic information on the medium, such as when writing information on the magnetic stripe of the passbook, it is desirable that the medium and the medium processing means (for example, a magnetic head) are in close contact with each other. .

  The end of the passbook can be aligned with the guide member serving as a conveyance reference by the guide member movable in the medium width direction, but the medium is bent by the force received from the movable guide member. For this reason, the medium processing unit cannot be brought into close contact with the medium, and a processing error such as a writing error occurs.

5A and 5B are a plan view and a side view showing the detection mechanism 60. FIG.
6A and 6B are plan views showing the detection mechanism 60 (detection state 1 and 2).

  A medium processing apparatus 1 shown in FIG. 1 includes a first guide member 10, a second guide member 20, an urging mechanism 30, an urging release mechanism 40, and a magnetic head 50 which is an example of a medium processing unit. , A detection mechanism 60, a conveyance path 70, and conveyance rollers 81, 82, and 83.

The first guide member 10 and the second guide member 20 are arranged so as to face each other, and guide a medium 100 (see FIGS. 8A to 10) such as a passbook, a form, and paper, for example.
The first guide member 10 and the second guide member 20 are plate-like members having a longitudinal direction in the conveyance direction (vertical direction in FIG. 1) of the medium 100.

  Since the first guide member 10 serves as a conveyance reference, the first guide member 10 is fixed to the conveyance path 70 so as not to move in the present embodiment. On the other hand, the second guide member 20 is urged toward the first guide member 10 by an urging mechanism 30 described later.

  The second guide member 20 is connected to an urging release shaft 44 described later at the center of the surface opposite to the contact surface with the medium 100. Further, the second guide member 20 has connecting pins 20a and 20b for connecting the second guide member 20 to a base member 31 to be described later, on the surface opposite to the abutting surface. Two are provided so as to be located on both sides. Note that an inlet-side guide member 73 is disposed on the conveyance path 70 on the inlet side (lower side in FIG. 1) of the medium 100 in the conveyance direction with respect to the second guide member 20.

  The second guide member 20, the urging mechanism 30, and the urging release mechanism 40 are disposed so as to be accommodated in the second guide member opening 72 of the conveyance path 70 in a plan view.

As illustrated in FIGS. 2A to 3C, the biasing mechanism 30 includes a base member 31 and a leaf spring 32 that is an example of an elastic member.
The base member 31 includes a vertical portion 31a, a horizontal portion 31b, and an attachment piece 31c, and is disposed so as not to move.

  The vertical portion 31 a is provided in parallel with the second guide member 20. The horizontal portion 31b extends away from the second guide member 20 from the lower end of the vertical portion 31a. The attachment piece 31c is provided on the horizontal portion 31b in order to attach a drive source 41 described later. The shape of the base member 31 has a horizontal portion 31b for disposing a link rotation shaft 46 of an urging release mechanism 40, which will be described later, but the base member 31 has a first portion sandwiching an elastic member (plate spring 32). What is necessary is just to oppose the two guide members 20.

  The leaf spring 32 is disposed between the vertical portion 31a of the base member 31 and the second guide member 20, and urges the second guide member 20 toward the first guide member 10. As described above, other elastic members such as a plurality of compression springs may be used instead of the plate spring 32 as long as the second guide member 20 is urged toward the first guide member 10.

The second guide member 20 is connected by connecting pins 20a and 20b so that the distance between the second guide member 20 and the base member 31 does not exceed a certain value.
The bias release mechanism 40 includes a drive source 41, a drive shaft 42, a link member 43, a bias release shaft 44, a rotation receiving member 45, and a link rotation shaft 46.

  The drive source 41 is a solenoid, for example, and as an example of a direction different from the urging direction of the second guide member 20 (arrow a shown in FIGS. 1 and 2A), in the present embodiment, the conveyance direction of the medium 100 ( The drive shaft 42 is pulled in the direction of arrow A) shown in FIGS. 8A and 8B to move straight.

  The link member 43 rotates about a link rotation shaft 46 erected vertically above the horizontal portion 31 b of the base member 31, for example. The link member 43 has an engagement piece 43 a that engages with the drive shaft 42, and converts the linear motion of the drive shaft 42 into a rotational motion.

  The bias release shaft 44 is connected to the center of the second guide member 20 on the side opposite to the contact surface with the medium 100 (for example, fixed integrally with the second guide member 20). Yes. The bias release shaft 44 passes through the vertical portion 31 a of the base member 31 and the link member 43.

  The rotation receiving member 45 shown in an enlarged manner in FIG. 4 is connected to the side opposite to the second guide member 20 across the link member 43 of the bias release shaft 44. In the present embodiment, the rotation receiving member 45 is connected to the tip of the urging release shaft 44 in the connection hole 45c. However, the rotation receiving member 45 can also be connected to the second guide member 20 side with the link member interposed between the bias release shafts 44. In that case, the urging release shaft 44 may not penetrate the link member 43.

  The rotation receiving member 45 includes a plurality of protrusions 45a and 45b arranged in the axial direction (vertical direction in the present embodiment) of the link rotation shaft 46 with the bias release shaft 44 interposed therebetween, that is, with the connection hole 45c interposed therebetween. Have.

  The protrusions 45a and 45b according to the present embodiment have a cylindrical surface having an axis in the arrangement direction as a cross-sectional shape perpendicular to the arrangement direction has a semicircular shape. The protrusions 45a and 45b are in line contact with the surface of the link member 43 in a linear shape extending in the arrangement direction.

  When the projections 45a and 45b are in surface contact with the link member 43, it is difficult to convert the projections 45a and 45b into a force for pulling the second guide member 20 when the link member 43 is rotated. It is preferable to make line contact or point contact with respect to the arrangement direction (axial direction of the link rotation shaft 46).

  The rotation receiving member 45 pulls the second guide member 20 via the urging release shaft 44 by receiving the rotation of the link member 43 at the protrusions 45a and 45b (a second contact surface shown by a broken line in FIG. 2B). To the second guide member 20 indicated by a solid line). Thereby, the urging | biasing to the 1st guide member 10 side of the 2nd guide member 20 is cancelled | released.

  In addition, since the rotation receiving member 45 receives rotation of the link member 43, it is desirable that the rotation receiving member 45 be made of a material resistant to wear. In the present embodiment, the material of the link member 43 is a metal, whereas the material of the rotation receiving member 45 is a resin. Further, if the projections of the rotation receiving member 45 are arranged in the rotation axis direction of the link member 43 (the axial direction of the link rotation shaft 46) with the bias release shaft 44 interposed therebetween, at least the bias release shaft 44 is sandwiched. A plurality may be provided on one side.

  The magnetic head 50 moves with respect to the magnetic stripe 101 (see FIGS. 8A to 8D) of the stationary medium 100 while moving in the magnetic head opening 71 of the conveyance path 70 in the plan view in the conveyance direction of the medium 100. Touch and read / write magnetic information. Note that other medium processing means such as a print head may be used instead of the magnetic head 50.

  As shown in FIGS. 5A to 6B, the detection mechanism 60 includes an actuator 61, a shielding plate 62, a photosensor 63 that is an example of a medium detection unit, a detection mechanism link 64, a tension spring 65, and a torsion spring. 66 and a detection mechanism link rotation shaft 67.

  The actuator 61 is disposed at a position facing the second guide member 20 and has a cylindrical shape or a disk shape with the vertical direction as an axis. A part of the actuator 61 protrudes closer to the second guide member 20 than the first guide member 10. The actuator 61 rotates when the portion protruding from the first guide member 10 contacts the medium 100 being conveyed.

  A notch 61 a is formed in a part of the outer periphery of the actuator 61. The rotation angle of the actuator 61 is regulated by the notch 61a coming into contact with a rotation stopper 64a of a detection mechanism link 64 described later. The actuator 61 is rotatably supported by the detection mechanism link 64. Then, by being pressed in contact with the medium 100, the detection mechanism link rotation shaft 67, which is the rotation shaft of the detection mechanism link 64, can be rotated.

  The shielding plate 62 is fixed to the actuator 61 and rotates around the central axis of the actuator 61 together with the actuator 61. Accordingly, the shielding plate 62 moves to the transmission state of the photosensor 63 when the medium 100 shown in FIG. 6A is carried in and when the medium 100 shown in FIG. 6B is carried out.

  When the medium 100 is at the processing position (medium 100 (P)) shown in FIGS. 8C and 8D, the actuator 61 is kept pressed against the medium 100, and the shielding plate 62 is kept in the transmissive state. The Thereby, the detection mechanism 60 can detect that the medium 100 (P) at the processing position is in contact with the first guide member 10.

  On the other hand, when the medium 100 moves from the processing position to the carry-in side (the upper side in FIGS. 8C and 8D) or the carry-out side and does not come into contact with the actuator 61, the tension spring 65 pulls the actuator 61 to return to the initial position shown in FIG. .

  The torsion spring 66 shown in FIGS. 5A and 5B is wound around the detection mechanism link rotation shaft 67 and biases the actuator 61 in a direction protruding from the first guide member 10 via the detection mechanism link 64.

  The above-described configuration of the detection mechanism 60 is merely an example, and any other contact-type detection mechanism may be used as long as it detects that the medium 100 is in contact with the first guide member 10. Alternatively, a non-contact type detection mechanism that detects the medium 100 without contact with the medium 100 may be used.

In the conveyance path 70 shown in FIG. 1, for example, a plurality of sets (three sets in the present embodiment) of conveyance rollers 81, 82, 83 arranged in a pair of upper and lower and a pair of left and right are arranged in the conveyance direction.
Hereinafter, the flow of medium processing will be described, but since it overlaps with the above description, detailed description thereof will be omitted.

FIG. 7 is a flowchart showing the flow of medium processing. It is assumed that the operation of each unit of the medium processing apparatus 1 is controlled by a control device (not shown).
8A to 8D are plan views showing the medium processing apparatus 1 for explaining the flow of the medium processing.

9A and 9B are views of the medium 100 of the medium processing apparatus 1 in FIG. 8C as viewed from the IX direction.
FIG. 10 is a diagram of the medium 100 of the medium processing apparatus 1 in FIG. 8D viewed from the X direction.

  First, as shown in FIG. 8A, the medium 100 carried into the transport path 70 is transported by transport rollers 81 to 83 (transport direction A). The distance between the first guide member 10 and the second guide member 20 is set to be smaller than the width of the medium 100. Since the second guide member 20 is urged toward the first guide member 10 by the urging mechanism 30 (the urging direction a), when the medium 100 is conveyed as shown in FIG. 8B. The second guide member 20 is pressed by the medium 100 to the side opposite to the urging direction, but presses the medium 100 against the first guide member 10.

  Then, as shown in FIG. 8C, the medium 100 is conveyed to the processing position (medium 100 (P)) by the magnetic head 50 (step S301), and when this is detected by a sensor (not shown), the medium by the conveying rollers 81 to 83 is detected. The conveyance of 100 stops (step S302).

  At this time, since the medium 100 presses the actuator 61 of the detection mechanism 60, the detection mechanism 60 detects that the medium 100 is in contact with the first guide member 10 (YES in step S303). If not (NO in step S303), the process starts again from the conveyance of the medium 100 (step S301).

  When the detection mechanism 60 detects that the medium 100 is in contact with the first guide member 10 (YES in step S303), the bias release mechanism 40 is driven by the drive source 41 as described above. As shown in FIG. 8D, the bias of the second guide member 20 is released by moving the link 42 straightly, rotating the link member 43 and pulling the second guide member 20 (bias release direction b, step S304). .

  When the medium 100 is pressed against the first guide member 10 side by the second guide member 20, the medium 100 bends at the end portion as shown by a solid line in FIG. 9A, and is magnetic as shown in FIG. 9B. At the time of magnetic reading / writing by the head 50, the magnetic head 50 cannot be brought into close contact with the medium 100, and a processing error such as a writing error occurs.

  On the other hand, when the bias of the second guide member 20 is released as described above, the medium 100 is not pressed against the first guide member 10 side by the second guide member 20, and as shown by a solid line in FIG. It can be in close contact with the magnetic head 50.

  However, since the medium 100 may not be pressed against the first guide member 10 by the second guide member 20, there is a possibility that the medium 100 may be misaligned. 10 is again detected. If not detected (NO in step S305), the bias release by the bias release mechanism 40 is stopped (that is, the movement state of the drive shaft 42 by the drive source 41 is returned to the initial state), and the bias mechanism 30 causes the second release. After the guide member 20 is returned to the state of being biased toward the first guide member 10 (step S306), the medium 100 is transported again (step S301).

  When it is detected again that the medium 100 is in contact with the first guide member 10 (YES in step S305), the magnetic head 50 performs magnetic processing (reading / writing of magnetic information) on the medium 100 (step S305). S307).

  Then, by canceling the bias release by the bias release mechanism 40 after the magnetic processing, the bias guide 30 returns the state where the second guide member 20 is biased toward the first guide member 10 (step S308). ). However, when the positional accuracy of the medium 100 is not required for the subsequent transport of the medium 100 or the like, it is not necessary to return to the biased state.

Thus, the medium processing is completed, but when the medium processing apparatus 1 is, for example, a passbook printer, the following operations such as bookkeeping are performed.
In the medium processing apparatus 1 according to the embodiment described above, the first guide member 10 and the second guide member 20 are arranged to face each other and guide the medium 100. The urging mechanism 30 urges the second guide member 20 toward the first guide member 10. The bias release mechanism 40 releases the bias of the second guide member 20 by the bias mechanism 30. A magnetic head 50 as an example of a medium processing unit performs magnetic processing or printing on the stationary medium 100. The detection mechanism 60 detects that the medium 100 (P) at the processing position by the magnetic head 50 is in contact with the first guide member 10. The bias release mechanism 40 releases the bias of the second guide member 20 when the detection mechanism 60 detects that the medium 100 is in contact with the first guide member 10, and the magnetic head 50. Performs processing on the medium 100 in a state where the bias release mechanism 40 releases the bias of the second guide member 20.

Therefore, even if the configuration in which the medium 100 is pressed against the first guide member 10 by the second guide member 20 and the urging mechanism 30, the magnetic head 50 is stopped from being pressed against the first guide member 10. The processing can be performed on the stationary medium 100. Thereby, the medium 100 can be prevented from being bent by being pressed against the first guide member 10, and the magnetic head 50 can be in close contact with the medium 100. Therefore, according to the present embodiment, it is possible to reliably perform processing on the medium 100.

  In the present embodiment, the urging mechanism 30 is disposed between the base member 31 and the base member 31 and the second guide member 20, and the second guide member 20 is connected to the first guide member 10. And a leaf spring 32 (an example of an elastic member) biased to the side. The bias release mechanism 40 includes a drive source 41, a drive shaft 42 that moves straight in a direction different from the bias direction (arrow a) of the second guide member 20 by the drive source 41, and the drive shaft 42. The link member 43 that rotates and moves together, the bias release shaft 44 that is connected to the second guide member 20 and penetrates the base member 31, and is connected to the bias release shaft 44 to rotate the link member 43. And a rotation receiving member 45 that pulls the second guide member 20 through the bias release shaft 44 by receiving. The rotation receiving member 45 is arranged in the rotation axis direction of the link member 43 (the axial direction of the link rotation shaft 46, which is the vertical direction in the present embodiment) across the bias release shaft 44 and contacts the link member 43. A plurality of protrusions 45a and 45b are in contact with each other.

  Therefore, the gear ratio can be adjusted by using the link member 43. For example, even if the driving force of the driving source 41 is weakened, the second guide member 20 can be pulled. Furthermore, by using the link member 43, the arrangement space of the bias release mechanism 40 can be adjusted. Therefore, the configuration of the drive source 41 and the like can be simplified. Further, since the plurality of protrusions 45 a and 45 b are arranged in the direction of the rotation axis of the link member 43 with the bias release shaft 44 interposed therebetween, the rotation movement of the link member 43 is caused by the force pulling the second guide member 20. Can be reliably converted.

  In the present embodiment, the magnetic head 50 is configured such that the medium 100 is in contact with the first guide member 10 in a state where the bias release mechanism 40 releases the bias of the second guide member 20. When the detection mechanism 60 detects again, the medium 100 is processed. Therefore, even if the medium 100 is misaligned due to the bias release mechanism 40 releasing the bias of the second guide member 20 and the medium 100 cannot be pressed against the first guide member 10 side, Since this can be detected, it is possible to reliably perform processing on the medium 100.

  In the present embodiment, the detection mechanism 60 is a contact-type detection mechanism that protrudes closer to the second guide member 20 than the first guide member 10 and contacts the medium 100. Therefore, the bias release of the second guide member 20 can be performed in a state where the contact of the medium 100 with the first guide member 10 is detected with high accuracy.
