Abstract

PURPOSE:To correct the change of a spring coefficient by providing a holding member to hold down the center of a linear spring to the main body side and changing the position to hold down a linear spring by a holding member. CONSTITUTION:A magnetic head holder 6, when a magnetic head 5 is inserted to an aperture 7, is abutted to an end part 7a of the aperture 7. The aperture 7 is constituted longer than an aperture 8 in the lateral direction, and at the aperture 7, the position of the magnetic head 5 can be changed and fitted to three stages of the lateral direction. At the central part of both sides of the magnetic head holder 6, a projection 13 to engage a groove 11 and a groove 12 is provided, the magnetic head holder 6 is fitted on a frame 1, and then, the projection 13 at the both sides is engaged to the groove 11 and the groove 12. The edge part of a linear spring 14 is abutted to the projection 13 of the magnetic head holder 6, pressed down by a plate material 17 and the linear spring 14 oppresses the magnetic head holder 6 and the magnetic head 5 in the lower direction. Thus, with a simple constitution, the spring coefficient change caused by accompanying the change of the fitting position of the magnetic head can be suppressed.

Description

[Detailed description of the invention] Industrial application field The present invention records various information on a card magnetically,
Alternatively, the present invention relates to a magnetic card recording/reproducing device for reproducing information from a card.

2. Description of the Related Art Conventional magnetic card recording and reproducing devices are compatible with only specific types of cards, and the mounting position of the magnetic head is determined by the position of the magnetic recording band on the card used. A linear spring is provided to press the magnetic head toward the card insertion hole so that the recording/reproducing surface of the magnetic head reliably contacts the top of the card. This linear spring is arranged on the main body so as to be perpendicular to the node insertion direction, one end of which is fixed to the main body, and the other end engaged with the magnetic head.

Problems to be Solved by the Invention However, with the above-described conventional device, it is not possible to handle multiple cards with different positions of magnetic recording bands, so it is necessary to change the configuration of the main body and the linear spring depending on the card used. This resulted in an increase in costs.

In addition, in order to be compatible with various cards, the main body is configured in advance so that the mounting position of the magnetic head can be changed along a method perpendicular to the card insertion direction, and the magnetic head of the card to be used can be recorded. A method may also be considered in which the position of the magnetic head is selected depending on the position of the band, and in each case the magnetic head is compressed by a common linear spring fixed at one location. However, when the magnetic head approaches the fixed part of the linear spring, the distance between the fixed part on the linear spring and the engaging part that hits the magnetic head becomes smaller, and the spring coefficient when pressing the magnetic head becomes thicker. (As a result, the elastic force applied to the magnetic head becomes too large, causing a problem in that the recording and reproducing surfaces of the magnetic card and the magnetic head are accelerated in wear.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a magnetic card recording and reproducing device that has a simple configuration and can suppress changes in the spring coefficient that occur when changing the mounting position of a magnetic head. With the goal.

Means for Solving the Problems In order to solve the above problems, the present invention has a linear spring that presses the magnetic head into the card insertion hole in the main body so as to be orthogonal to the card insertion direction, and the tip end of the spring is arranged perpendicular to the card insertion direction. Providing a pressing member that engages with the magnetic head, is attached so that its base portion engages with the frame side, and presses the center portion of the linear spring, and changes the position at which the pressing member presses the linear spring. It was configured so that it is possible.

By configuring as described above, when the magnetic head mounting position is moved to correspond to several types of cards with different positions of information recording bands on the cards, the position where the linear spring hits the magnetic head changes. Even if the spring coefficient changes due to this change, it is possible to correct the change in the spring coefficient by changing the position of the linear spring pressed by the pressing means.
