The media processing device described in Patent Document 1 includes a magnetic data reading/writing unit that reads magnetic data recorded on a card-shaped recording medium such as a train ticket and writes magnetic data to the recording medium. The magnetic data read/write section includes a first magnetic head section having two magnetic heads, a second magnetic head section having two magnetic heads, a third magnetic head section having two magnetic heads, and a recording and a transport mechanism for transporting the medium.

JP 2013-30075 A

In the recording medium used in the medium processing device described in Patent Document 1, the interval between three tracks of magnetic data in the width direction of the recording medium, which is perpendicular to the transport direction of the recording medium and the thickness direction of the recording medium, is relatively narrow. Therefore, one 3-channel type magnetic head can read 3-track magnetic data from one surface of the recording medium and record 3-track magnetic data. On the other hand, there are recording media in the market on which magnetic data on multiple tracks are recorded, and in which the width between tracks in the width direction of the recording medium is relatively wide.

When processing such a recording medium, it is difficult to read and record magnetic data on multiple tracks with a single wide magnetic head. Therefore, the inventors of the present application are considering arranging a plurality of magnetic heads in the width direction of the recording medium in a medium processing apparatus for processing such recording medium. Further, when a plurality of magnetic heads are arranged in the width direction of the recording medium, it becomes difficult to secure installation space for the belt that conveys the recording medium. are considering transporting

However, since the conveying force of the recording medium by the conveying roller is generally smaller than the conveying force of the recording medium by the belt, when conveying the recording medium by the conveying roller, a plurality of magnetic heads are arranged in the width direction of the recording medium. When the front end of the recording medium conveyed by the conveying roller comes into contact with a plurality of magnetic heads arranged in the width direction of the recording medium, the recording medium is tilted with respect to the magnetic heads due to the external force acting on the recording medium. The study by the inventor of the present application has revealed that there is a possibility that the (skew, azimuth) increases and affects the magnetic data reading performance and the magnetic data recording performance.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the problem of a recording medium being conveyed by a conveying roller, and even when a plurality of magnetic heads are arranged in the width direction of the recording medium. An object of the present invention is to provide a medium processing device capable of suppressing inclination.

In order to solve the above problems, the media processing apparatus of the present invention includes a medium transport path for transporting a card-shaped recording medium, a medium transport mechanism for transporting the recording medium on the medium transport path, and a medium transport mechanism for transporting the recording medium on the medium transport path. and a magnetic data processing mechanism that performs at least one of reading magnetic data recorded on the recording medium and recording magnetic data on the recording medium conveyed on the medium conveying path, and recording conveyed on the medium conveying path The width direction of the recording medium is defined as a direction orthogonal to the medium conveyance direction and the thickness direction of the recording medium conveyed on the medium conveyance path, one of the width directions of the recording medium is defined as a first direction, and the opposite direction is defined as the first direction. is the second direction, the magnetic data processing mechanism includes a plurality of magnetic heads arranged in the width direction of the recording medium, and the medium transport mechanism is arranged in the width direction of the recording medium and is in contact with the recording medium. A plurality of transport rollers for transporting a recording medium are provided, the plurality of magnetic heads and the plurality of transport rollers are arranged at offset positions in the transport direction of the recording medium, and the plurality of magnetic heads arranged in the width direction of the recording medium. The magnetic head closest to the first direction is called the first magnetic head, and the magnetic head closest to the second direction is called the second magnetic head. Let the transport roller closest to the first direction be the first transport roller, and the transport roller closest to the second direction be the second transport roller. At least part of the magnetic head and at least part of the first transport roller are arranged at the same position in the width direction of the recording medium, and at least part of the second magnetic head and at least part of the second transport roller are arranged at the same position on the recording medium. are arranged at the same position in the width direction.

In the media processing device of the present invention, one of the width directions of the recording medium is defined as the first direction, and the opposite direction of the first direction is defined as the second direction. , at least a portion of a first magnetic head arranged closest to the first direction, and a first conveying roller arranged closest to the first direction among a plurality of conveying rollers arranged in the width direction of the recording medium. are arranged at the same position in the width direction of the recording medium, and at least part of the second magnetic head arranged closest to the second direction side and the second magnetic head arranged closest to the second direction side At least part of the transport roller is arranged at the same position in the width direction of the recording medium.

Therefore, in the present invention, even if the recording medium comes into contact with the plurality of magnetic heads arranged in the width direction of the recording medium and an external force acts on the recording medium, the conveying amount of the recording medium in the first direction side of the medium conveying path remains unchanged. , it is possible to suppress the occurrence of a difference in the conveying amount of the recording medium on the second direction side of the medium conveying path. Therefore, in the present invention, even when the recording medium is conveyed by the conveying rollers and a plurality of magnetic heads are arranged in the width direction of the recording medium, the inclination of the recording medium with respect to the magnetic heads can be minimized. can be suppressed.

It is also possible to suppress the inclination of the recording medium with respect to the magnetic head by narrowing the gap in the width direction of the recording medium between the guide members that are arranged on both sides in the width direction of the recording medium and guide the recording medium in the transport direction. is. However, in this case, the width of the recording medium processed by the media processing device varies, and when a recording medium with a relatively wide width is taken into the media processing device, the recording medium is caught by the guide member and is pushed out. There are cases where it cannot be transported. On the other hand, in the present invention, even if the gap between the guide members in the width direction of the recording medium is widened, it is possible to suppress the inclination of the recording medium with respect to the magnetic head, so this problem does not occur.

In the present invention, the center of the first magnetic head in the width direction of the recording medium and the center of the first transport roller in the width direction of the recording medium are arranged at the same position in the width direction of the recording medium. It is preferable that the center of the second magnetic head in and the center of the second transport roller in the width direction of the recording medium are arranged at the same position in the width direction of the recording medium.

With this configuration, even if the recording medium comes into contact with the plurality of magnetic heads arranged in the width direction of the recording medium and an external force acts on the recording medium, the transport amount of the recording medium in the first direction side of the medium transport path is maintained. It is possible to effectively suppress the occurrence of a difference between the conveyance amount of the recording medium on the second direction side of the medium conveyance path and the conveyance amount of the recording medium. Therefore, it is possible to effectively suppress the inclination of the recording medium with respect to the magnetic head. Also, even if the recording medium is a relatively soft medium such as a paper medium, deformation of the recording medium such as twisting when the recording medium comes into contact with a plurality of magnetic heads arranged in the width direction of the recording medium is suppressed. becomes possible.

In the present invention, for example, two magnetic heads, a first magnetic head and a second magnetic head, are arranged in the width direction of the recording medium, and two conveying rollers, a first conveying roller and a second conveying roller, are used for recording. They are arranged in the width direction of the medium.

In this case, when viewed from the thickness direction of the recording medium, the first magnetic head and the second magnetic head are arranged symmetrically with respect to the center line of the medium transport path in the width direction of the recording medium. It is preferable that the transport roller and the second transport roller are arranged symmetrically with respect to the center line of the medium transport path in the width direction of the recording medium. With this configuration, even if the recording medium comes into contact with the two magnetic heads arranged in the width direction of the recording medium and an external force acts on the recording medium, the recording medium is transported in the first direction side of the medium transport path. A difference between the amount and the conveyed amount of the recording medium on the second direction side of the medium conveying path is less likely to occur. Therefore, it is possible to more effectively suppress the inclination of the recording medium with respect to the magnetic head. In addition, even if the recording medium is a relatively soft medium such as paper, it is possible to suppress the twisting of the recording medium when the recording medium contacts multiple magnetic heads arranged in the width direction of the recording medium. become.

It is a two-channel type magnetic head having two channels for performing at least one of them.

In the present invention, the magnetic data processing mechanism includes, for example, a plurality of magnetic heads facing the medium transport path from one side in the thickness direction of the recording medium, and a plurality of magnetic heads facing the medium transport path from the other side in the thickness direction of the recording medium. and a magnetic head. In this case, it is possible to process the recording medium even if the recording medium on which magnetic data is recorded faces in which direction the recording medium is loaded into the medium processing device.

It is preferable to detect whether the recording medium is inserted into the media processing device with one surface or the other surface of the recording medium facing one side in the thickness direction of the recording medium. With this configuration, detection is performed to detect whether the recording medium is inserted into the medium processing device with one surface or the other surface of the recording medium facing one side in the thickness direction of the recording medium. It is possible to simplify the configuration of the media processing device as compared with the case where the mechanism is provided separately.

In the present invention, the medium processing device includes, for example, guide members arranged on both sides of the medium transport path in the width direction of the recording medium and guiding the recording medium in the transport direction of the recording medium.

In the present invention, the magnetic data processing mechanism includes a pad roller facing the magnetic head, a contact position that rotatably holds the pad roller and allows the pad roller to contact the recording medium, and the pad roller that is separated from the medium transport path. a roller holding member rotatable with the width direction of the recording medium as the axial direction of rotation between a retracted position and a retracted position; and a rotating mechanism rotating the roller retaining member between the contact position and the retracted position. The rotation mechanism includes a first biasing member that biases the roller holding member toward the retracted position, a cam follower that is fixed to the roller holding member, and a cam surface that contacts the cam follower. A cam member that is slidable in the medium transport direction, a second biasing member that biases the cam member to one side in the recording medium transport direction, and a solenoid that moves the cam member to the other side in the recording medium transport direction. The cam surface includes a first cam surface that is a plane perpendicular to the thickness direction of the recording medium, and one end of the first cam surface in the recording medium conveying direction and inclined with respect to the thickness direction of the recording medium. The cam follower contacts the cam surface by the biasing force of the first biasing member, and the cam member moves to one side in the conveying direction of the recording medium by the biasing force of the second biasing member. When the cam follower is in contact with the first cam surface, the roller holding member is placed at the contact position, and the solenoid is driven to move the cam member to the other side in the conveying direction of the recording medium. It is preferable that the cam follower comes into contact with a position deviated from the cam surface and the roller holding member is arranged at the retracted position.

With this configuration, when the roller holding member is arranged at the contact position, the cam follower is in contact with the first cam surface perpendicular to the thickness direction of the recording medium. Even if a force acts on the roller holding member to rotate it toward the retracted position, no force acts on the cam member in the direction in which the recording medium is conveyed. Therefore, even if the biasing force of the second biasing member is weakened, it is possible to retain the roller holding member arranged at the contact position at the contact position.

As described above, in the media processing apparatus of the present invention, even when the recording medium is transported by the transport roller and a plurality of magnetic heads are arranged in the width direction of the recording medium, the magnetic It is possible to suppress the inclination of the recording medium with respect to the head.

However, in this case, the width of the recording medium 2 processed by the media processing device 1 varies. is caught and the recording medium 2 cannot be conveyed. On the other hand, in the present embodiment, even if the distance between the two guide members 25 is large, it is possible to suppress the inclination of the recording medium 2 with respect to the magnetic heads 30 to 35, so this problem does not occur. .

In this embodiment, the magnetic heads 30 and 31 detect whether the recording medium 2 is inserted into the media processing device 1 with the front surface or the back surface 2a of the recording medium 2 facing upward. Therefore, in this embodiment, a detection mechanism is separately provided for detecting whether the recording medium 2 is inserted into the media processing device 1 with the front surface or the back surface 2a of the recording medium 2 facing upward. It is possible to simplify the configuration of the media processing device 1 as compared with the case where

In this embodiment, when the roller holding member 50 is arranged at the contact position 50A, the cam follower 54 is in contact with the first cam surface 55c perpendicular to the vertical direction.
