Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a magnetic recording/reproducing device, and more particularly to a magnetic head mounting structure for a manual magnetic card recording/reproducing device.

(Prior Art) Conventionally, in a magnetic head section of a manual magnetic card recording/reproducing device, a magnetic card is not necessarily slid parallel to a sliding surface within a guide groove for sliding a magnetic card. In consideration of this, a structure is provided to ensure close contact between the magnetic card and the magnetic headgap. For example, a rubber roller may be provided to press the magnetic card inserted into the guide groove against the magnetic head gap, or the entire magnetic head may be tilted to follow the inclination of the magnetic card surface, and the magnetic card surface may be tilted. A mechanism is provided for pressing the

(Problem that the invention aims to solve) However, with the former structure, a considerable amount of pressure is required to correct the inclination of the magnetic card using a rubber roller or the like and bring it into close contact with the magnetic head gap. It has the disadvantage of accelerating wear. Another disadvantage is that a complicated mechanism is required to realize the latter.

The present invention aims to provide a magnetic head mounting structure that can eliminate the above-mentioned drawbacks with a simple structure.

(Means for Solving the Problems) In the present invention, a guide frame has a groove for guiding the running of a magnetic card and a window facing the magnetic card guide groove, and the magnetic head is made to look into the window. A round bar spring extending in the running direction of the magnetic card is inserted into the rear of the magnetic head to enable the magnetic head to rotate relative to the round bar spring, and the magnetic card is inserted through the window. The round bar spring is movable in and out of the guide groove, and both ends of the round bar spring are held in the guide frame, and the round bar spring is also displaceable in the guide frame near the magnetic head only in the same direction as the direction in which the magnetic head moves in and out. It is characterized by the provision of a guide groove that allows for possible regulation.

(Function) The present invention allows the magnetic head to rotate in accordance with the inclination of the magnetic card inserted into the guide groove by pivoting the magnetic head with a round bar spring, and the magnetic head gear is always kept in position by the biasing force of the spring. It is designed so that it can be brought into close contact with the magnetic recording/reproducing part of a magnetic card with an appropriate pressure.

(Example) An example of the present invention will be described below with reference to the drawings.

1 and 2 are schematic sectional views of a manual magnetic card recording/reproducing device to which the present invention is applied, viewed from the side and above, respectively, and FIG. 3 shows the main parts of the magnetic head mounting structure. It shows.

The magnetic head 1 is pivotally attached to a case extension piece at its rear end by a round rod-shaped spring 3 extending in the sliding direction of the magnetic card 2 as indicated by the arrow in FIG. Both ends of the round bar spring 3 are fitted into fixing holes 42 formed in the guide frame 4 and held therein, and parts near both sides of the magnetic head 1 are inserted into guide grooves 41 formed in the guide frame 4. It is loosely fitted. In this way, the magnetic head 1 is prevented from swinging in the vertical direction in FIG.
The guide frame 4 is housed in a window formed in the guide frame 4 so as to be freely retractable from the guide frame 3 . Reference numerals 11 and 12 are lead-out portions for signal lines for magnetic recording and reproduction.

According to such a mounting structure, the magnetic head 1 can rotate in the direction a-a' around the round bar spring 3, as shown by the arrow in FIG.
Since the magnetic head 1 can be elastically deformed only in the b-b' direction along the guide groove 41, the movement of the magnetic head 1 in the vertical direction in FIG. Become.

The width of the magnetic card guide groove 43 formed in the guide frame 4 is made larger than the thickness of the magnetic card 2, but the head gap 1 of the magnetic head 1 can be inserted into the groove 43.
3 is made to protrude slightly. Therefore, as shown in FIG. 4, when the magnetic card 2 is inserted into the magnetic card guide groove 43 with an inclination in the depth direction, the magnetic head 1 adjusts the inclination of the surface of the magnetic card 2 around the round bar spring 3. The magnetic head gap 13 rotates in the direction of the arrow c to follow the direction of the arrow c, and is biased in the direction of the arrow d by the round bar spring 3, so that the magnetic head gap 13 applies an appropriate pressing force to the magnetic recording/reproducing section of the magnetic card 2. We will be in close contact with each other.

Furthermore, since the round bar spring 3 is restricted by a guide groove 41 in the vicinity of the magnetic head 1 so that it can only be displaced in the direction of the arrow b-b' in FIG. , magnetic head 1
Even if a force is applied in the vertical direction in FIG. 1 to the magnetic head 1, the position of the magnetic head 1 in the vertical direction in FIG. 1 does not shift.

Note that the present invention is not limited to the illustrated embodiment.

(Effects of the invention) As explained above, according to the invention, the magnetic head can be rotated with a simple structure in which the magnetic head is supported by a single round bar spring, and moreover, the magnetic head can be rotated within the magnetic card guide groove. It can be provided so that it can be displaced only in the direction in which it appears and disappears. As a result, even if the magnetic card is inserted at an angle, the magnetic head gap can always be brought into close contact with the magnetic recording/reproducing section. A low-cost and highly reliable manual magnetic card recording/reproducing device which has the advantage of being able to obtain output can be provided.
