Abstract

PURPOSE:To prevent occurrence of inclination of a magnetic head and damping at the time of card travelling by holding the magnetic head movably in the right angle direction with the carrier path in the state that the end of the protruded part is contacted with pressure with the surface which is in parallel with the magnetic card carrier path on the magnetic card reader main body side by elasticity of the head supporter. CONSTITUTION:In the elevating exercise of a magnetic head H, the operation to the upper side is regulated by elastic force of a head supporter 10, force which reacts on pushing-up force works, and the operation to the lower side is regulated by boss parts 14 and 14' of the head supporter 10. When a magnetic card C is inseted from the arrow A direction based on the above-mentioned constitution, the magnetic head H is swung instantaneously when the magnetic card C is hit on the magnetic head H, and force which is dislocated from the orthogonally intersected direction with card traveling, is applied. However, the head supporter 10 does not lower in the lower direction any more since the boss parts 14 and 14' of the head supporter 10 are contacted with the main body before the card is entered. Thus, dislocation between an end part (a) of the magnetic head H and the orthogonal shaft of the card is prevented.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a magnetic head holding structure in a magnetic card league used for member, credit, and data cards such as PO8 terminals, credit authorization terminals, and time recorders. It is related to.

(Conventional structure and its problems) Conventionally, the magnetic head holding structure of a magnetic card league that exchanges information via a magnetic card has a head support made of an elastic plate that holds a magnetic head H, as shown in Fig. 1. 1 and
It has a head support mounting plate 2 to which this head support 1 is attached, and this head support mounting plate 2 is attached to the head support mounting portion 5 of the magnetic card league main body 3 in which the card conveyance path 4 is formed by the head support mounting screw 7. The tip a of the magnetic head H, which is fixed with screws and held in the center of a head support 1 such as an elastic plate, is located in the card transport path 4 through a window 6 formed in the main body 3.

In this way, the magnetic head H is connected to the magnetic head H of the card conveyance path 4 of the main body in order to improve the adhesion with the magnetic card C when the magnetic card C is inserted into the card conveyance path 4 of the main body 30 of the magnetic cart reader. They are placed so that they are pressed against opposing surfaces. However, when a card with a deformed shape such as a curve is inserted, the head support 1 to which the magnetic head H is attached
Since the supporting part of the magnetic head H is fixed to the head support mounting plate 2 with countersunk screws 7, etc., the magnetic head H does not follow a curved card, etc., and uneven contact occurs, causing information from the card to be lost. Giving and receiving becomes insufficient.

In addition, when the card begins to run and the leading edge of the card hits the magnetic head, the magnetic head may damp up and down because there is no support for the magnetic head in advance, and the magnetic head and card are in close contact with each other. I feel like my sex has gotten worse. In addition, if the card running speed is too fast, the head support 1 will come into contact with the card at a position other than the designated one, as shown in Figures 2(a) to 2(b), and information exchange from the card will be interrupted. It has the disadvantage that it cannot be done accurately.

(Object of the Invention) The present invention aims to eliminate such drawbacks and provides a magnetic head holding structure that does not cause tilting or damping of the magnetic head during card running.

(Structure of the Invention) In order to achieve the above object, the magnetic head holding structure of the present invention has a head support made of an elastic plate for disposing the magnetic head in the magnetic card transport path of the magnetic card league body. Place a part of the board on both sides of the center part to be attached.
It has a fulcrum of the head support at the center of the hollowed out part, and has a protrusion protruding in the plane direction between the magnetic head mounting part and the fulcrum of the head support,
The elasticity of the head support holds the magnetic head movably in a direction perpendicular to the magnetic card conveyance path with the tip of the protrusion in pressure contact with a surface parallel to the magnetic card conveyance path on the side of the magnetic card league main body. It is characterized by the following.

(Description of Embodiment) An embodiment of the present invention will be described below based on the drawings. Third
The figure is a front view of the magnetic head holding structure according to the present invention, and FIG. 4 is a plan view thereof.

In the figure, lO is a head support such as an elastic plate with a magnetic head H attached to the head mounting part 11 in the center, and both sides are punched out as shown in the figure, and the center of the punched part is 12°12'. The head support mounting portions 13 and 13' of the magnetic card league main body 3, in which the card conveyance path 4 is formed, are fixed to the head support mounting screws 7 with screws to the portion 5, and serve as the fulcrum of the head support. . 14, 1
4' is a boss part provided symmetrically between the head attachment part 11 of the head support 10 and the attachment parts 13 and 13' of the head support, and the length dimension 11 of this boss part is the same as that of the magnetic card league body 3. For head support installation, the length dimension of parts 5 and 5' is 12
This makes the head support 10 slightly longer.
The magnetic head section is in a floating state in FIG. The mounting position of the magnetic RAD H fixed to the center part of the head support 10, that is, the head mounting part 11 by resin adhesion, welding, etc., is the number of the head support 10? space part 14,1
4' The front part of the head is located in the magnetic card conveyance path 4 through the window 6 provided in the magnetic card league main body 3, and its tip a is located in the magnetic card conveyance path 4. It is in contact with the side surface 4a farther from the head H, or is in a state with a slight gap.

With such a configuration, in the vertical movement of the magnetic head H, the upward movement is regulated by the elastic force of the head support 1o, and a pushing force and a reaction force act, while the downward movement is controlled by the boss portion of the head support 10. 14 and 14'. When the magnetic card C is inserted in the direction of the arrow A under the above configuration, the magnetic card C is inserted into the magnetic head H.
At the moment when the magnetic head H swings as shown in FIG. 1(b) in the conventional example, a force is applied in the direction perpendicular to the card travel. 14 and 14' are in contact with the main body before the card is inserted, so the head support 10 does not go down any further and is restrained by the post 14 on the left side, thereby aligning the tip a of the magnetic head H with the orthogonal axis of the card. This prevents misalignment. Also,
Even if the magnetic card C is inserted at high or low speed in the direction of arrow A, and the magnetic head H is momentarily lifted upward, as mentioned above, the magnetic head H is constantly subjected to downward force even before the card C is inserted. Because of this, the magnetic head H has a hard time grounding. Furthermore, when the magnetic force field is inserted into the head support 10, the magnetic head H can be smoothly moved up and down using the portions 15 and 15' as fulcrums. Furthermore, even if a curved deformed card is inserted, the head support 10
Since the magnetic head 15 and 15' are used as fulcrums to move from side to side, followability is good, and therefore, the contact between the magnetic head and the magnetic card is improved, and information transmission from the card is ensured. Further, in the case of the above embodiment, the component structure is symmetrical, and even if the magnetic card is inserted from the direction of the reed arrow B, the same result can be obtained.

(Effects of the Invention) As is clear from the above explanation, according to the magnetic head holding structure of the present invention, tilting or damping of the magnetic head does not occur when a card is run, and the magnetic head can follow curved cards, etc. If the magnetic card has good performance, information can be sent and received from the magnetic card reliably at all times. Furthermore, since the magnetic head holding structure of the present invention is composed of a single component, it can be used for different standards, is highly versatile, and has great practical effects.
