Abstract

PURPOSE:To improve the reading performance by engaging a conical projection at both side faces orthogonal to the card running direction of a magnetic head mount seat with a recessed part of a head mount fixed plate so as to bring the head into contact onto the card always at a proper pressure. CONSTITUTION:The conical projection 12 at both side faces 11a of a magnetic head mount seat 11 holding a magnetic head 11 and a recessed part 13 of a magnetic head mount seat fixed plate 14 supported elastically to a magnetic card reader main body 6 are engaged with each other. When the magnetic head 2 is in contact with the magnetic head 1, the mount seat 11 is supported freely turnably orthogonal to the card running direction and the head traces the card even if the card is bent. Thus, the head 1 is in close contact onto the card 2 always at a proper pressure to improve the read performance.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic head support device for a magnetic card reader used for reading magnetic cards such as bank cash cards and credit cards.

2. Description of the Related Art A conventional magnetic head support device will be described below with reference to FIG. FIG. 4 is a plan view of a conventional magnetic head support device. In FIG. 4, l slides in contact with the magnetic card 2, and the magnetic strip (not shown) of the magnetic card 2
This is a magnetic head for reading the above data, and as shown in FIG. It is being At both ends of the magnetic head mounting seat 3 are flat magnetic head mounting seat fixing plates 4t.

It is supported by a bin 5 at a certain distance.

Further, both ends of the magnetic head mounting seat fixing plate 4 are fixed to the magnetic card reader main body 6 with screws 7 and supporting members 8I.

The operation of the magnetic head support device configured as described above will be described below. When the magnetic card 2 comes into contact with the magnetic head l, the magnetic head 1 is pushed up by Cζ because the magnetic head mounting seat 3 has elasticity.

Pressure is applied to the magnetic card 2, while the magnetic head mounting seat 8
As shown in Fig. 6, with the pins 5 on both sides as the center,
The magnetic head 1 rotates in the direction indicated by the arrow in accordance with the warpage of the magnetic card 2, and the magnetic head 1 rotates left and right in the direction indicated by the arrow C, which is orthogonal to the running direction of the magnetic card 2. In this way, the magnetic head 1 rotates left and right, and the magnetic head 1 comes into close contact with the magnetic card 2 with appropriate pressure.
The data on the magnetic nut drive (not shown) of the magnetic card 2 can be read at the .

Problems to be Solved by the Invention However, in the conventional configuration, since the magnetic head mounting seat 8 is attached to the magnetic head mounting seat fixing plate 4 with the pin 5, the magnetic head mounting seat 8 cannot be rotated from side to side. At this time, the magnetic head mounting seat 8 does not rotate smoothly due to the friction between the magnetic head mounting seat 8 and the bottle 5, and the magnetic head l cannot smoothly follow the warpage of the magnetic card 2. Therefore, the magnetic head 1 is not always in close contact with the magnetic card 2, and there is a problem in that the performance of the magnetic head 11 in reading data from the magnetic card 2 is reduced.

The present invention solves the above-mentioned problems, and in order to improve the performance of reading data from a magnetic card by keeping the magnetic head in close contact with the magnetic card at all times, the present invention adjusts the magnetic head to cope with the warping of the magnetic card. The object of the present invention is to provide a magnetic head support device that allows smooth tracking.

Means for Solving the Problems The present invention provides a magnetic head mounting seat with a pair of conical protrusions or recesses on both left and right sides perpendicular to the running direction of the magnetic card. A top portion of a magnetic head mounting seat fixing plate that supports the magnetic head mounting seat and has elasticity is in point contact with the top of the conical projection or recess of the magnetic head mounting seat at a position opposite to the conical projection or recess of the magnetic head mounting seat. This is a T-komono with a conical concave or convex portion.

Effect: With the above configuration, the magnetic head mounting seat is supported by the conical convex and recessed parts in point contact with the magnetic head mounting seat fixing plate, and the magnetic head rotates smoothly around the point contact area. It also smoothly follows the warping of the magnetic card.

The magnetic head and magnetic card will always be in close contact with each other.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a magnetic head support device showing one embodiment of the present invention. Components that are the same as those in the conventional example are given the same reference numerals and descriptions thereof will be omitted. In FIG. 1, reference numeral 11 denotes a magnetic head mounting seat, and conical convex portions 12 are provided on both left and right side surfaces 11a of the magnetic head mounting seat 11 perpendicular to the running direction of the magnetic card 2. The mounting seat 11 is made of an elastic magnetic head mounting seat fixing plate 14 which is provided with a conical recess 18 having a top in point contact with the top of the projection 12 at a position opposite to the projection 12. As shown in the drawings and FIG. 8, the magnetic card 20 is rotatably supported in the direction of the arrow C perpendicular to the running direction. Further, one end of the magnetic head mounting seat fixing plate 14 is fixed to the magnetic card reader main body 6 by a screw 15 and a support member 16.

The operation of the magnetic head support device configured as described above will be described below. The magnetic card 2 is the magnetic head 11
When this comes into contact, the magnetic head 1 is pushed up due to the elasticity of the magnetic head mounting seat fixing plate 141, and the magnetic head 2 is pushed up.
pressure is applied to - The magnetic head mounting seat 11 is configured such that the magnetic card 1 is centered at the point contact between the conical recess 13 of the magnetic head mounting seat fixing plate 14 and the conical protrusion 12 of the magnetic head mounting seat 11. It rotates smoothly in the direction of the arrow in FIG. 2 in accordance with the warpage, and the magnetic head 1 also smoothly rotates left and right in the direction of arrow C, which is orthogonal to the running direction of the magnetic card 2. In this way, the magnetic head 1 rotates smoothly and smoothly follows the warpage of the magnetic card 2, so the magnetic head 1 can always come into close contact with the magnetic card 2 with a moderate pressure, and the magnetic head IG Data reading performance of the magnetic card 2 can be improved.

Note that by providing a concave portion in place of the convex portion 12 of the magnetic head mounting seat 11 and a convex portion in place of the concave portion 18 of the magnetic head mounting seat fixing plate 14, the magnetic head mounting seat 11 is attached to the magnetic head mounting seat fixing plate 14. It may be supported by point contact.

As described above, according to the present invention, the rotation of the magnetic head is improved by bringing the magnetic head mounting seat and the magnetic head mounting seat fixing plate into point contact on both sides of the magnetic head mounting seat perpendicular to the running direction of the magnetic card. The movement becomes smooth 1ζ, the magnetic head can better follow the warpage of the magnetic card, and the magnetic head can always be in close contact with the magnetic card with appropriate pressure. Therefore, the glare detection performance of the magnetic card is improved, and its practical effects are significant.
