Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a magnetic head support device used in a magnetic card reader.

Usually, this type of magnetic head is fixed to a leaf spring, and this leaf spring is supported by a support plate, and the support plate is usually fixed to a base frame. However, if the position of the magnetic track provided on the magnetic card is different, the set position of the magnetic head must also be changed accordingly. For this reason, in the past, support plates were used to support the leaf springs in different support positions for the leaf springs each time. According to this, since the relative positions of each support plate and the magnetic head are different, by fixing the support plate at a fixed position on the base frame, the magnetic head can be made to face magnetic tracks at different positions on the magnetic card. You will be able to support yourself. However, this has the inconvenience of requiring a separate support plate for each magnetic card having magnetic tracks in different positions.

The purpose of this invention is to enable one type of support plate to be used for different types of magnetic cards, and to facilitate the installation of the support plate.

An embodiment of this invention will be described with reference to the drawings. Reference numeral 1 denotes a base frame, and a support plate 2 is fixed with screws 3 across a pair of support parts 1A. 3A is a screw hole. A long hole 4 is formed on both ends of the support plate 2, and a screw 3 is inserted through this long hole 4.
The support plate 2 is movable with respect to the screws 3 in a direction perpendicular to the paper plane in FIG. 1, and is fixed to the surface of the support portion 1A by the screws 3 at an appropriate position. A pair of hemispherical protrusions 5 and a pin portion 6 extending downward from the lower part of the protrusions 5 are provided on the lower surface of the support plate 2 . Further, the support plate 2 is provided with pieces 7a and 7b at both ends of both side edges. This is support plate 2
It can be easily configured by bending a part of it into a U-shape. Reference numeral 8 denotes a hole having a shape that allows the magnetic head 9 to pass through.

Reference numeral 10 denotes a leaf spring, through which a magnetic head 9 is fixedly fixed in the center, and is placed astride between a pair of upright walls 1B provided on the base frame 1. In the mounting position, the pin part 6 is inserted into a small hole (not shown) formed in the leaf spring 10, and the protruding part 5 supports the leaf spring 10 by pressing it from the surface, and the support plate 2 is fixed. Therefore, by fixing the support plate 2 as described later, the installation position of the magnetic head 9 can be determined depending on the fixed position. 11 is a path through which the magnetic card passes, and 12 is a guide thereof. It goes without saying that the magnetic card is adapted to pass through a fixed position within the passageway 12.

A plurality of pairs of grooves are provided on the surfaces of both support parts 1A. The examples in the diagram are grooves Aa, Ab, grooves Ba, Bb, and grooves.
Three pairs of Ca and Cb are shown.
Pieces 7a and 7b of the support plate 2 can be fitted into each groove.

In the above configuration, when the support plate 2 is fixed to the support portion 1A with the screws 3, the pieces 7a and 7b are fitted into one of the pair of grooves, such as the grooves Aa and Ab. Then, it is fixed to the support portion 1A with screws 3. This fixed position determines the relative position of the magnetic head 9 within the passage 11. For a different type of magnetic head having a different magnetic track position, the pieces 7a and 7b may be fixed by fitting into another pair of grooves, for example, grooves Ba and Bb. At this time, the relative position of the magnetic head 9 in the passage 11 is different from the previous case, so that the magnetic head 9 can be positioned relative to the magnetic track of a different type of magnetic card. Become.

In the illustrated example, both the pieces 7a and 7b are provided, but it may be provided with either one of them, and in this case, the grooves do not need to be formed in pairs.

As detailed above, according to this invention, the same support plate can be used for magnetic cards with different magnetic track positions, eliminating the need to install a separate support plate for each magnetic card and supporting The relative position of the magnetic head with respect to the magnetic card can be determined by simply inserting a piece of the plate into the groove, making positioning extremely easy. Since the extent to which they can be formed can be narrow, a large number of them can be formed even within a limited area.
