[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic card reader / writer, and more particularly, to a magnetic card reader / writer which can be formed compactly.

[0002]

2. Description of the Related Art In recent years, a magnetic card reader / writer has been widely used as an apparatus for recording and reproducing magnetic data such as an ID card and a prepaid card.

However, the conventional magnetic card reader / writer has a problem that the means for transporting the magnetic card to be recorded / reproduced is complicated and large, and it is difficult to form the entire apparatus compact.

The configuration of a conventional magnetic card reader / writer will be described with reference to FIGS.

FIG. 8 is a longitudinal sectional view of a conventional magnetic card reader / writer, and FIG. 9 is a bottom view of the same. 8, reference numeral 1 denotes a magnetic card, and C denotes a main body case of a conventional magnetic card reader / writer. The magnetic card 1 is transported in the direction of arrow N (from left to right in FIG. 8).

In the main body case C, an upper guide 30 and a lower guide 31 are provided between the carry-in portion 29 and the carry-out portion 33, and a transport path along the arrow N direction is provided between these guides 30, 31. 32 are formed. Reference numeral 2 denotes a take-in roller provided on the upstream side of the upper guide 30, reference numeral 3 denotes a feed roller provided in the middle, and reference numeral 4 denotes a feed roller provided on the downstream side. Reference numeral 20 denotes a motor.
The motors 3 and 4 are driven by a motor 20 and a transmission means described below.

More specifically, reference numeral 21 denotes a motor pulley which is mounted on the output shaft of the motor, 22 denotes a large pulley which is mounted on the feed roller 3, and 23 denotes a belt wound around these pulleys 21 and 22. Then, as shown in FIG. 9, these pulleys 21 and 22 and the belt 23 are provided outside the side of the main body case C. 27a is a relay pulley that is axially mounted on the side of the feed roller 3 opposite to the large pulley 22;
7b is a pulley that is pivotally mounted on the take-in roller 2, 27c is a pulley that is pivotally mounted on the feed roller 4, and 28 is a relay pulley 27a
And a belt wound around each of the pulleys 27b and 27c. And, these pulleys 27a, 27b, 2
The belt 7c and the belt 28 are provided outside the side of the main body case C. Therefore, when the motor 20 is driven, the motor pulley 21 and the large pulley 22 rotate,
The feed roller 3 rotates. At the same time, the rotation of the relay pulley 27a, the pulleys 27b, 27c causes the intake roller 2 and the feed roller 4 to rotate.

As described above, in the conventional magnetic card reader / writer, a large number of pulley groups 2 are provided.
1, 22, 27a, 27b, 27c and belts 23, 2
8 constituted the above-mentioned transmission means. Therefore, there is a problem that a large installation space is required for these transmission means, and the entire device becomes complicated and large.

Accordingly, an object of the present invention is to provide a magnetic card reader / writer which can be formed compactly.

Reference numeral 8 denotes a magnetic head provided at the same position as the feed roller 3 in the transport direction (the direction of the arrow N), 8a a holder for the magnetic head 8, 5, 6, 7 take-in rollers 2, and feed rollers 4, 3 And the pressing roller provided on the lower guide 31 side. The magnetic card 1 includes a take-in roller 2 and a pressing roller 5, a feed roller 3 and a pressing roller 6, a feeding roller 4 and a pressing roller 7, It is conveyed while being pinched. Reference numeral 24 denotes a wire spring whose base end is fixed to the lower guide 31 via a holding member 25 by a screw 26, and whose front end urges the pressing rollers 5, 6, 7 upward.

[0011]
