DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic head supporting device for a magnetic card reader used for a cash card or a credit card of a bank.

[0002]

2. Description of the Related Art A conventional magnetic head support device will be described below. As shown in FIGS. 4 and 5, an elastic magnetic head mounting seat 8 mounted so that the magnetic head 9 moves up and down is supported by two pins 11 inserted into holes of the magnetic head mounting seat 8. The mounting seat fixing plate 10 is disposed. The mounting seat fixing plate 10 is fixed to the main body 13 of the magnetic card reader with two screws 12. Reference numeral 14 denotes a magnetic card.

[0003] The operation of the magnetic head supporting apparatus constructed as described above will be described below. Magnetic card 14
Is inserted into contact with the magnetic head 9, the magnetic head 9
Is pushed up due to the spring property of the magnetic head mounting seat 8, and pressure is applied to the magnetic head 9. Further, a force such that the magnetic head mounting seat 8 fluctuates in the direction shown by the arrow in FIG. Receive. Thus, the data on the magnetic stripe of the magnetic card 14 is read by bringing the magnetic head 9 into close contact with the magnetic card 14 with an appropriate pressure.

[0004]

However, in the above-mentioned conventional construction, the magnetic head mounting seat is supported by the pins inserted into the holes, so that the magnetic head mounting seat is left and right orthogonal to the card running direction. When rotating in the direction, the magnetic head mounting seat does not move smoothly due to friction between the magnetic head mounting seat and the pin. Also, since the mounting fixing plate is fixed with two screws, the magnetic card JIS,
There was a problem that the magnetic head could not be easily positioned at all of the ISO standard track positions.

The present invention solves the above-mentioned conventional problems. The magnetic head can be smoothly rotated in accordance with the running direction of the magnetic card, and the adhesion between the magnetic head and the magnetic card can be improved. It is an object of the present invention to provide a magnetic head support device that can easily position a magnetic head at all track positions of a card according to JIS and ISO standards.

[0006]

In order to achieve this object, a magnetic head supporting device according to the present invention comprises a pair of spring positioning portions disposed orthogonally to a running direction of a magnetic card;
It has a configuration provided with a round bar-shaped U-shaped spring attached to the head holder together with the magnetic head and disposed at the spring positioning portion, and a configuration provided with a plurality of fitting holes in the spring positioning portion.

[0007]

According to this structure, the magnetic head receives elastic force in the vertical direction perpendicular to the running direction of the magnetic card and improves the rotation in the horizontal direction.

[0008] Further, the magnetic head is arranged in accordance with the position of the track of the magnetic card.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, a pair of spring positioning portions 7 are arranged on the main body 4 of the magnetic card reader in a direction perpendicular to the running direction of the magnetic card.
The round bar-shaped U-shaped spring 1 is attached to the head holder 6 together with the magnetic head 2, is fitted and set in the spring positioning portion 7, and is fixed by the spring retainer 3. 5 is a magnetic card.

The operation of the magnetic head supporting device configured as described above will be described below. When the magnetic card 5 runs on the card slide surface of the main body 4 of the magnetic card reader and contacts the magnetic head 2 to reproduce the data of the magnetic stripe, the magnetic head 2 is pushed down by the magnetic card 5. At this time, the round bar-shaped U-shaped spring 1 attached together with the magnetic head 2 by the head holder 6 is deformed. However, since the round bar-shaped U-shaped spring 1 is fixed by the spring retainer 3, its elasticity causes the magnetic head to be deformed. Apply pressure to 2. Here, the round bar-shaped U-shaped spring 1 smoothly rotates the magnetic head 2 in the vertical direction perpendicular to the card running direction by bending and twisting due to the shape of the spring. Since the round bar-shaped U-shaped spring 1 has a round outer shape, it rotates the magnetic head 2 in the right and left direction (the direction indicated by the arrow in FIG. 2) perpendicular to the card running direction.

Further, if the spring positioning portion 7 is provided with a fitting hole 7a for fitting the round bar-shaped U-shaped spring 1 at regular intervals, the round bar-shaped U-shaped spring 1 is fitted into the predetermined fitting hole 7a. Thus, the position of the magnetic head can be moved perpendicular to the running direction of the magnetic card 5.

As described above, according to the present embodiment, a pair of spring positioning portions disposed in the traveling direction of the magnetic card, and a round bar-shaped member mounted on the head holder together with the magnetic head and disposed on the spring positioning portion. By providing the U-shaped spring, the spring can be miniaturized by the elasticity due to the bending and torsion of the round bar-shaped U-shaped spring, and the magnetic card running along the body of the magnetic card reader allows the magnetic head to be mounted on the magnetic card. The magnetic head can be smoothly rotated in the up-down direction and the left-right direction orthogonal to the traveling direction, the adhesion between the magnetic head and the magnetic card is good, and the reading of the magnetic card can be performed accurately and smoothly.

Further, the magnetic head can be easily arranged in conformity with the track position of the magnetic card according to JIS and ISO standards.

[0015]

As will be apparent from the above description of the embodiment, the present invention is characterized in that a pair of spring positioning portions disposed perpendicular to the running direction of a magnetic card and a magnetic head are attached to a head holder. With the configuration including the round bar-shaped U-shaped spring provided in the spring positioning portion and the configuration in which a plurality of fitting holes are provided in the spring positioning portion, the magnetic head is smoothly rotated according to the traveling direction of the magnetic card. An excellent magnetic head which can improve the adhesion between the magnetic head and the magnetic card, can read the magnetic card accurately and smoothly, and can easily arrange the magnetic head at a position corresponding to the track position of the magnetic card. A support device can be realized.
