As described above, in the card reader 1, the magnetic head module 50 is fixed to the upper frame 18 only by the screws 53, 54, and the pad roller module 60 is fixed to the lower frame 17 only by the screws 64, 65. Therefore, by removing the magnetic head module 50 from the upper frame 18 and replacing it with another module, and removing the pad roller module 60 from the lower frame 17 and replacing it with another module, magnetic information recording media of different standards can be produced. It is possible to divert to a device corresponding to In other words, the card reader 1 is manufactured simply by replacing the set of the magnetic head module and the pad roller module in the device corresponding to the magnetic information recording medium of different standards with the set of the magnetic head module 50 and the pad roller module 60. becomes possible.

FIG. 10 is a side view schematically showing a schematic configuration of a card reader 1A that can be diverted to the card reader 1 of FIG. The card reader 1A is a magnetic information recording medium processing device capable of recording and reading magnetic information on a card 2A conforming to the JIS-I standard. In the card reader 1A, the magnetic head module 50 is replaced with a pad roller module 80 including a pad roller 81, and the pad roller module 60 is replaced with a magnetic head module 70 including a magnetic head 71 facing the pad roller 81. It has the same configuration as the card reader 1 in FIG. 1 except for the points. The card 2A has a magnetic stripe 2a formed on the back surface of the card 2 shown in FIG.

11 is a perspective view of the card reader 1A shown in FIG. 10 with the magnetic head module 70 and the pad roller module 80 removed from the body frame 16. FIG. 12 is an exploded perspective view of the card reader 1A shown in FIG. 10 with the magnetic head module 70 removed from the lower frame 17. FIG.

The magnetic head module 70 is arranged so that the tip of the magnetic head 71 faces the card transport path 4 from below. The magnetic head module 70 supports the magnetic head 71 so that the magnetic head 71 can be rotated with the front-rear direction as the axial direction of rotation, and the magnetic head 71 can be moved vertically. A magnetic head support portion 71S is provided. The magnetic head support portion 71S includes a plate spring 72 that rotatably supports the magnetic head 71 with the left-right direction as the axial direction of rotation, and support pins 73a that are inserted through two insertion holes formed in the plate spring 72, respectively. , 73b are formed, and includes a fixed member 73 fixed to the lower frame 17 by screws 74 and 75, and a compression coil spring 76 that biases the plate spring 72 upward.

The pad roller module 80 is arranged so that the pad roller 81 faces the card transport path 4 from above. A rotating shaft 82 of the pad roller 81 is fixed to the upper frame 18 by a screw.

In the card reader 1A, the accuracy of the angle formed by the extending direction of the magnetic gap of the magnetic head 71 and the front-rear direction is not required so much. Therefore, unlike the card reader 1 shown in FIG. 1, the magnetic head module 70 does not require an adjustment hole.
