Description

[Detailed Description of the Invention] The present invention relates to a magnetic recording medium reader that records or reproduces information by slidingly contacting a magnetic recording medium such as a magnetic passbook with a moving magnetic head.

A magnetic bankbook reader, which is an example of a conventional magnetic recording medium reader, is a magnetic bankbook reader, which is an example of a conventional magnetic recording medium reader, as shown in Figure 1.
A magnetic head 7 records or reproduces information on a magnetic recording band 5 provided on the back side of the reader. Those equipped with both functions, such as a printing section 8 that operates as a printer, are often used. Actual reader operation is often performed by sliding a magnetic head in reciprocating motion against a stationary passbook.

In conventionally known magnetic recording medium readers of this type, the above-mentioned magnetic head is held in a fixed state or is configured to be held rotatably. However, if the magnetic head is held in a fixed state, it will not follow the recording medium such as a bankbook, and if it is held in a rotatable manner, the magnetic head may tilt too much due to impact or other reasons. If this happens, the magnetic head will not return to its previous state and will no longer be able to come into contact with the recording medium, which has the disadvantage that it cannot guarantee that the magnetic head will be in proper contact with the magnetic recording medium. I found out.

The present invention has been made to solve the above-mentioned drawbacks, and the present invention is designed to rotatably hold the magnetic head and to set the rotation angle of the magnetic head on a support member that runs together with the magnetic head. The magnetic recording medium is regulated by a regulating means, thereby ensuring an appropriate state of contact with the magnetic recording medium.

The present invention will be explained below with reference to illustrated embodiments. Second
4, the magnetic passbook reader as a magnetic recording medium reader has a magnetic passbook passage 3 formed by frame plates 1 and 2, and a magnetic passbook 4 inserted into the lower passbook passage of the magnetic recording band 5 which is stopped. A window hole 6 is formed. The magnetic recording strip 5 is attached to the back side of the bankbook, and a magnetic head 7, which projects from the window hole 6 and runs in the direction of the hole, slides into contact with it to record or reproduce information.
A print section 8 is arranged in front of the window hole 6 of the passbook passage 3.

The magnetic head 7 is attached to a head holder 9, and the head holder 9 is attached to a support plate 10 with pins 1.
1, and the support plate 10 is fixed to a lever 12. The lever 12 is held on a holding plate 14 by a shaft 13 so as to be able to rotate freely in the vertical direction, and is urged by a spring 15 in the direction of the bankbook, thereby forming a pad pressure generating means. Lever 12
A roller 16 is provided on the base frame 17, and is in contact with a cam surface 18b of a position regulating plate 18 attached to the base frame 17. The holding plate 14 has two guide rods 19,
It is held by a screw 19 and is provided so as to be freely movable laterally by a screw screw 20. The window hole 6 is formed in the magnetic passbook passage 3 in a direction perpendicular to the direction in which the passbook 4 is inserted.

As mentioned above, the magnetic head 7 is held by the pin 11 so as to be able to swing freely, and the rotation angle α of the head due to this swing is determined by
The amount is limited to a certain amount by the pin 21 fixed to the support plate 10 and the notch 9a provided in the head holder 9. That is, this rotation angle α is set by the pin 21 fixed to the support plate 10 facing into the notch 9a provided in the head holder 9, and the rotation angle α is set by the pin 21 fixed to the support plate 10 facing into the notch 9a provided in the head holder 9. It will not tilt any further.

An L-shaped posture regulating plate 22 is fixed to the base frame 17 at the left and right stopping positions of the reciprocating movement of the magnetic head 7, and is brought into contact with one side of the magnetic head at the stopping position to regulate the posture. The head stands vertically.

When the magnetic passbook reader is configured as described above and the magnetic head 7 is being fed by the screw screw 20, the roller 1 is attached to the cam surface 18a of the position regulating plate 18.
6 is brought into contact with the magnetic head 7, and the magnetic head 7 rises and runs in sliding contact with the magnetic recording band 5. In this state, the magnetic head 7
As mentioned above, since it is held by the pin 11 so that it can freely swing at a certain angle, it can contact the passbook in an appropriate state, and the rollers can be moved at the left and right limit stop positions of the reciprocating movement. 16 is lowered by the cam surface 18b of the position regulating plate 18, and one side of the magnetic head is regulated by the attitude regulating plate 22 to stand vertically. Therefore, the sliding contact surface of the magnetic head 7 is held down parallel to and perpendicular to the magnetic recording band 5, and writing and reading operations are performed instantaneously during the next sliding contact movement of the magnetic head, resulting in worsening of write jitter, etc. The shortcomings of will be resolved.

As described above, the present invention provides a regulating means for rotatably holding the magnetic head and for regulating the rotation angle of the magnetic head, between the holding member of the magnetic head and the magnetic head (in the embodiment, the regulating means The pin 21 fixed to the magnetic head 10 and the notch 9a) provided in the head holder 9 prevent the disadvantage that the magnetic head may be tilted too much due to the operating condition, which adversely affects the recording and reproduction of information. It can be prevented without any problem.

For example, in the above embodiment, the posture of the magnetic head is regulated and controlled even in the stopped state, but if the magnetic head is tilted significantly due to some reason such as an impact, the magnetic head will be tilted significantly when the magnetic head is in the stopped state. Even if the magnetic head is equipped with a posture control mechanism, this mechanism will not function, but in the present invention, since the rotation angle of the magnetic head is regulated, such a situation can be prevented. It is possible.
