Description

[Detailed description of the invention] This invention has a gently meandering surface on one side.
A first guide frame in which the gap of the magnetic recording/reproducing head is exposed on one of the protruding surfaces of the meandering surface, and a magnetic material having a meandering surface similar to the meandering surface of the first guide frame and coated with a magnetic material. This magnetic card reader consists of a second guide frame that is slightly wider than the thickness of the card and has guide grooves arranged so that the spacing between both meandering surfaces is equal.

A thin magnetic card coated with a magnetic material and having a certain thickness is manually inserted into a spaced guide groove.
Magnetic card readers are used to record on or read from magnetic materials.

The guide grooves of conventional magnetic card readers that can be inserted by hand are parallel, and when the magnetic card moves within the guide groove, the magnetic gap of the magnetic recording/reproducing head that protrudes from a part of the guide groove is securely connected to the magnetic material. must have been in contact with. Therefore, the magnetic recording/reproducing head must be supported by elastic springs, rubber, etc., or the magnetic recording/reproducing head must be moved so that the magnetic recording/reproducing head contacts the magnetic material of the magnetic card within the parallel guide grooves. An elastic part is provided in the guide groove, which pushes the magnetic card from the back side and brings the magnetic recording/reproducing head and the magnetic material into close contact. However, in these conventional methods, providing a resilient mechanism within a narrow guide groove complicates the mounting structure of the magnetic recording/reproducing head, and has disadvantages in terms of handling, such as the magnetic card getting caught when inserted. I have it.

The present invention eliminates such drawbacks of the conventional one, and has a meandering guide groove for inserting and running a magnetic card reader.
The gap of the magnetic recording/reproducing head is projected and fixed on the protruding surface of the meandering surface, so that the structure is simple, the handling operation is easy, and the contact between the magnetic body and the magnetic recording/reproducing head is improved.

The present invention will be explained below with reference to the drawings.

As shown in the embodiment shown in FIG. 1, the present invention has a gap 4 of a magnetic recording/reproducing head 3 mounted on a protruding surface 2 approximately at the center of the meandering surface of a first guide frame 1, which has one surface that meanders gently. expose. Also this first
A second guide frame 6 having a meandering surface 5 similar to that of the guide frame 1 is arranged at an interval slightly larger than the thickness of the magnetic card 7 coated with a magnetic material to be inserted, and the interval between the meandering surfaces of both guide frames is set. Guide groove 8 such that
to form. The first guide frame 1 and the second guide frame 6 thus formed are integrated to form the insertion port 9.

As shown in FIG. 2, the magnetic card 7 inserted through the insertion slot 9 comes into contact with the magnetic gap 4 of the magnetic recording/reproducing head 3 near the center of the guide groove 8. Moreover, the magnetic gap 4 is located on the protruding surface 2 of the meandering surface of the first guide frame 1, and the magnetic card 7 is disposed on the protruding surface 2', 2'' of the second guide frame 2 facing the magnetic gap 4.
is curved. However, due to the restoring force of the magnetic card 7, the magnetic gap 6 of the magnetic recording/reproducing head 3 and the magnetic material of the magnetic card 7 come into close contact.

As described above, since the guide groove 8 in which the magnetic card 4 is inserted and runs according to the present invention is meandering, the magnetic card 7 is caused by the friction between the magnetic recording/reproducing head 3 and the guide frames 1 and 6. The magnetic material of the magnetic card 7 and the magnetic gap 4 of the magnetic recording/reproducing head 3 are in close contact with each other, and there is no need for a mechanism for press-bonding the magnetic recording/reproducing head 3 and the magnetic card 7 as in the conventional case, and the structure is simplified. A simple, low-cost, and highly reliable magnetic card reader can be obtained.

Claims (1)

[Scope of utility model registration request] The first guide frame, which exposes the magnetic gap of the magnetic recording/reproducing head on one protruding surface of the meandering surface where one side meanders gently, is spaced apart from the first guide frame by a distance slightly wider than the thickness of the magnetic card coated with a magnetic material. A magnetic card reader in which a guide groove is formed between a meandering surface of a first guide frame and a second guide frame having a similar meandering surface on one side.
