A first touch roller 30 is rotatably supported on a first shaft portion 26 of the shaft 24 by being engaged via a sleeve 32, and a second touch portion is provided on a second shaft portion 27. The roller 31 is rotatably supported by being engaged via the sleeve 33. Since the E-ring 34 is engaged with the annular groove 27a of the second shaft portion 27, the removal of the first and second touch rollers 30, 31 from the shaft 24 is restricted.

As described above, when the first and second touch rollers 30 and 31 are positioned so as to be shifted from each other by δ,
The support by one shaft 24 not only reduces the number of shafts, but also eliminates the need for mounting brackets.
The number of parts is reduced, and the assembling work is simplified. In FIG. 1, reference numeral 35 denotes a support shaft suspended above the rear side of the lower case 2 in a direction perpendicular to the card transport direction AB.

Next, based on FIG.
Will be described. The upper case 3 is formed in a shallow dish shape with an upper opening, and the hook 40 formed at the rear end portion is engaged with the support shaft 35 of the lower case 2 described above. With the center of rotation, the front end is configured to be openable and closable in the direction of arrow CD in the figure. When the front end of the upper case 3 is rotated in the direction of arrow D, and the upper case 3 closes the upper part of the lower case 2, a magnetic force is generated between the bottom 41 of the upper case 3 and the card transfer section 4 of the lower case 2. The card transport paths 42 are formed at intervals slightly larger than the thickness of the card 6.

A window 43 is formed at the bottom 41 of the upper case 3 so as to face the window 11 of the lower case 2.
Above the front end of the window 43, a pinch roller 45 facing the drive roller 12 of the lower case 2 is rotatably supported. Above the rear end of the window 43, a pinch roller 46 facing the driven roller 13 is rotatably supported.

6 is a pinch roller opposed to 6.

Next, the processing operation of a card in the card reader having such a configuration will be described. 1 and 2, when the magnetic card 6 is inserted from the card insertion / return port 10a, the magnetic card 6 is detected by a detection unit (not shown), and a motor (not shown) rotates in a forward direction, and a driving roller is driven. 2 rotates counterclockwise in FIG. 2, so that the drive belt 14 travels in the direction of arrow A. Following this travel, the driven belt 47, which is in contact with the drive belt 14, also travels in the direction of arrow A, so that the magnetic card 6 is conveyed in the direction of arrow A so as to be sandwiched between the two belts 14, 47. You.

When the magnetic card 6 is positioned on the magnetic head 21, the first and second touch rollers 30, 31
As a result, the magnetic card 21 is pressed against the first and second reading sections 21a and 21b of the magnetic head 21, and the magnetic information recorded on the magnetic card 6 is read.

When it is determined that the magnetic card 6 is a normal card, the rotation of the motor is temporarily stopped, so that the magnetic card 6 stops on the card transport unit 4. Thereafter, when the provision of the service by the device provided with the card reader 1 is completed, the motor rotates in the reverse direction, and the magnetic card 6 turns to the arrow B.
And is positioned on the magnetic head 21, and the magnetic head 21 rewrites the value information such as the balance. After the rewriting is completed, a punch hole corresponding to the rewriting of the value information is made by the punch unit 18 and returned from the card insertion / return port 10a.

In this embodiment, the magnetic head 21
Of the first and second reading units 21a and 21b.
However, three or more pieces may be used. Further, although two reading units are provided for one magnetic head, two or more magnetic heads having one reading unit may be provided. Although the boss 25a of the base 25 is formed in a D-cut shape to restrict the rotation of the shaft 24 attached to the side plate 20, it may be formed in an H-cut shape, and various design changes are possible. is there.
