Description

[Detailed description of the invention] This invention is used, for example, in commuter ticket issuing machines, automatic ticket gates, etc., and can be used to write magnetic information,
Or it relates to a magnetic recording device that performs reading.

In conventional magnetic recording devices, the pressing mechanism of the magnetic head has two parts, upper and lower, as shown in Figures 1 and 2.
A magnetic recording card A, which is held at both ends by a pair of conveyor belts 1 and 1, is attached to a magnetic head 3 fixed to a magnetic head mount 2, and a bearing 5 to a fixed shaft 4.
It is designed to be in pressure contact with a rotatable pressure roller, such as a rubber roller 6, which is inserted through the magnetic head 3, and by pressing the magnetic recording card A against the magnetic head 3, magnetic information can be written or Reading is performed. However, the above card A
When it is conveyed to the magnetic head 3, it is decelerated by the rubber roller 6, which causes magnetic writing defects, so as a means to prevent this magnetic writing defect, the metal part of the rubber roller 6 is brought into contact with one side of the conveyor belt 1. I am trying to force it to rotate.

However, since the rubber roller 6 is of a so-called fixed type that is fitted onto a shaft 4 attached to the substrate 7, there is an inconvenience that the magnetic head itself must be removed from the mounting base 2 when cleaning the magnetic head 3. Another drawback is that malfunctions are likely to occur due to poor installation during resetting.

The present invention was developed in view of the above circumstances, and its purpose is to provide a magnetic recording device that has a simple configuration, allows easy cleaning of the magnetic head, and prevents malfunctions during resetting. This is what we are trying to provide.

The present invention will be explained below based on an embodiment shown in FIGS. 3 and 4. However, since the same reference numerals as in FIGS. 1 and 2 indicate the same parts, the explanation will be omitted. In FIG. 4, a support shaft 11 on which a lever 12 is rotatably fitted is mounted on the substrate 7, while a fixed shaft 13 is fixed to one end of the lever 12, and the above-mentioned pressing force is attached to the fixed shaft 13. A roller, for example a rubber roller 6, is rotatably supported via a bearing 5. A stopper 14 is provided in the clockwise direction of the lever 12, which rotates about the support shaft 11, for positioning the rubber roller 6 integrally formed with the lever 12.

Further, one end of a U-shaped spring 15 is attached to the other end 12a of the lever 12 to bias the lever 12 toward the magnetic head 3.
2 is locked by rotating it counterclockwise against the tension of a spring 15. The lever 12 is swingably attached to the support shaft 11. For this reason, the other end 12 of the lever 12 to which one end of the U-shaped spring 15 is attached
a moves in an arc around the support shaft 11. When the rubber roller 6 is in contact with the magnetic head 3, the lever 12 is urged clockwise by the urging force of the U-shaped spring 15. Further, when the rubber roller 6 is separated from the magnetic head 3, one end 12a of the lever 12 moves upward, and the lever 12 is urged counterclockwise by the urging force of the U-shaped spring 15. Then, the lever 12 is locked with the rubber roller 6 separated from the magnetic head 3.
Therefore, the rubber roller 6 can be easily cleaned when the lever 12 is locked.

Reference numerals 16A and 16B are guide plates for guiding both sides of the magnetic recording card A being conveyed, and these guide plates 16A and 16B are used to control the inclination when recording magnetic information as shown in FIG. 5 a or b. configured to prevent

As described above, since the pressure roller of the present invention, that is, the rubber roller 6 is configured to be able to rotate integrally with the lever 12, when cleaning the magnetic head 3, the lever 12 must be rotated counterclockwise against the tension of the spring 15. Cleaning can be easily performed by rotating and locking the rubber roller 6, and when resetting the rubber roller 6, rotate the lever 12 clockwise and lock it with the stopper 14, so that the rubber roller 6 is secured to the magnetic head. 3 and then driven, the magnetic recording card A is guided by both guide plates 16A and 16B and can be prevented from being conveyed at an angle.

Although one embodiment of the present invention has been described in which levers, springs, stoppers, etc. that can be rotated integrally with the pressure roller are arranged on the front side of the board, the present invention is not limited to this; The same objective as described above can be achieved even if the Furthermore, although the card is conveyed while being held at both ends thereof, it is also possible to hold only one end thereof.

As explained above, according to the present invention, the pressure roller that presses the magnetic recording card against the magnetic head is configured to be rotatable so that it can come into contact with and separate from the magnetic head surface, making it easier to clean the magnetic head. Moreover, it has excellent effects such as being able to perform magnetic recording reliably.
