Abstract

PROBLEM TO BE SOLVED: To correctly read the data of a card by varying a change of a tension applied to a head in accordance with the thickness of the card and making the head correctly come in touch with the face of the card. SOLUTION: When a magnetic stripe card is passed through a slit 24 formed in a housing 12, a magnetic stripe head 20 set at a vertical end wall A is pressed rearward because of a thickness of the magnetic stripe card thereby to read data recorded in the card. At this time, a lid plate 22 fixing the magnetic stripe head 20 presses a silicone tube 18, thus impressing a tension to the magnetic stripe head 20.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head tension structure of a magnetic card reader device,
More specifically, the present invention relates to a head tension structure using a silicon tube in which a silicon tube of a single shape is inserted to maintain the tension of the magnetic head and the performance of the head is increased.

[0002]

2. Description of the Related Art In the prior art, a magnetic stripe head is spot-welded to a leaf spring, and fixed edges formed on the upper and lower portions of the cushion spring are spot-welded and fixed to the magnetic stripe head to form a rigid plate. The plate springs are inserted and fixed in the pivots formed on the left and right sides of the rigid plate, and the screw is inserted into the through hole formed in the lower part of the rigid plate, and the head is tightened and fixed in the screw hole formed in the housing, so that an appropriate head tension is obtained. Provided.

[0003]

However, when the user uses a card, if a large number of cards are continuously used, a thick card is used, or a long time is used,
There was a problem that the head was easily worn by the strong tension of the leaf spring and the card was damaged.

The present invention has been devised in view of the above problems, and it is possible to prolong the life of the head by providing various changes in the tension applied to the head according to the thickness of the card. It is an object of the present invention to provide a head tension structure using a silicon tube that provides a smooth tilt function capable of accurately contacting a surface and prevents errors by accurately reading data when reading a card.

[0005]

SUMMARY OF THE INVENTION To achieve the above object, the present invention is a head cushion comprising a known housing and a magnetic stripe head, in which a rigid plate having the magnetic stripe head fitted therein and fixed thereto is fixed. And a pivot bracket in which the rigid plate is inserted, a head holder including a silicon tube in which the pivot bracket is inserted, and a housing in which the head holder is fitted and coupled to the housing is used. Provide a head tension structure.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below with reference to the accompanying drawings.

In the present invention, as shown in FIGS. 1 to 3, a vertical end wall A stands on one side and a vertical end wall A'corresponds to the other side.
A slit 24 is formed between the vertical end wall A and the vertical end wall A'to allow the card to advance, and a square through hole is formed in the vertical end wall A so that the magnetic stripe head 20 can be inserted. The magnetic stripe head 20 is attached to the rigid plate 22 at one outer side of the housing 12 where the vertical end wall A is formed.
The pivot bracket 14 shown in FIGS. 6 and 7 and the head holder 10 shown in FIGS. 8 and 9 are integrally formed.

That is, a square through hole 28 is formed in the central portion of the rigid plate 22, and the head 20 is fixed to the rigid plate 22 so that the magnetic stripe head 20 is inserted into the square through hole 28.

The magnetic stripe head 20
A semi-circular pivot support plate 30 is formed at both ends of the rigid plate 22 that is fixed to and integrally formed with each other. It is inserted in the pivot bracket 14 in which is formed.

Further, the insertion groove 2 is provided so that the silicon tube 18 shown in FIGS. 4 and 5 can be seated outside the through hole 28.
6, a pivot groove 36 is formed on the outer side near the insertion groove 26, and a pivot support portion 34 is formed so that the pivot bracket 14 can be inserted. The pivot bracket 36 is formed in the pivot groove 36 of the head holder 10. The pivot 16 formed in 14 is seated to form an integral structure.

The silicon tube 18 for providing the cushion of the magnetic stripe head 20 to the insertion groove 26 formed in the head holder 10 as described above.
, The rigid plate 22 to which the magnetic stripe head 20 is fixed is inserted into the pivot bracket 14, and then the pivot placket 14 is inserted into the head holder 10 and fitted into the housing 12.

The operation of the present invention thus constructed will be described below. When the magnetic stripe card is passed through the slit 24 formed in the housing 12, the magnetic stripe head 20 installed on the vertical end wall A is pushed backward by the thickness of the magnetic stripe card and recorded on the card. You will be able to read the existing data.

At this time, the rigid plate 22 fixing the magnetic stripe head 20 pressurizes the silicon tube 18 to provide tension to the magnetic stripe head 20.

Also, depending on the type of magnetic stripe card that passes through the slit 24, the silicon tube 18 can be used against the flow and bending of the card and the non-uniformity of the card thickness.
Provides a smooth tilt function to prevent errors when reading data and read accurate data.

[0015]

According to the present invention as described above, the fatigue limit is increased and the life of the head is extended as compared with the case where a metal plate spring is used, and it is easy to adjust the tension of the head according to the card thickness. Since the vertical tilt of the head is free within the slit range, the contact between the card and the head is always maintained so that accurate data can be read, and when the card is passed between the slits, the vibration generated from the head causes the silicon tube Is effective in reducing the noise caused by the swing of the head and preventing the error caused by the noise on the data.
