Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a "card head pressure contact roller for a magnetic head" for pressing a prepaid card (hereinafter referred to as a magnetic card) used in an automatic ticket vending machine, a telephone or the like to a magnetic head. "For details, by forming the pressure contact roller for the magnetic bar code part of the magnetic card to be smaller in diameter than the pressure contact roller for the magnetic track part by approximately the bar code protrusion, it is possible to adjust the gap between the magnetic head and the card pressure contact roller. The present invention relates to a card pressing roller for a magnetic head that can easily perform the above.

[Problems to be solved by conventional technology and device]

As is well known, in magnetic cards used in vending machines and telephones, as shown in Fig. 2, variable information such as the amount of money purchased when the card is purchased and the remaining balance when used is attached to one end of the back side in the width direction. It has a magnetic track part for magnetically recording, and the fixed information such as the card issuing agency code and denomination is magnetically recorded by a bar code raised about 10 microns from the card surface at the other end in the same width direction. It has a bar code part.

By the way, in the card pressing roller for the magnetic head of the automatic ticket vending machine that purchases a ticket using a magnetic card,
The pressure contact roller and the second pressure contact roller are coaxially arranged, the first pressure contact roller presses the magnetic track portion of the magnetic card to the variable information processing head portion of the magnetic head, and the second pressure contact roller the magnetic bar of the magnetic card. The code part is pressed against the fixed information processing head part of the magnetic head.

However, in the above card press contact roller for a magnetic head of an automatic ticket vending machine, since the first press contact roller and the second press contact roller are formed to have the same diameter, each of the first press contact roller and the second press contact roller is Since it is necessary to individually adjust the gap between the magnetic head and the magnetic head to a predetermined set value with a gap gauge, there is a problem that the adjustment work is time-consuming. Incidentally, in order to read and write the magnetic information of the magnetic card by the magnetic head, the gap between the magnetic head and the card pressing roller must be set with an accuracy of 1/100 mm.

Therefore, the present invention has been made by paying attention to the fact that the magnetic bar code portion of the magnetic card is raised from the card surface, and the magnetic bar code portion pressure roller of the magnetic card is pressed against the magnetic track portion. It is a technical object to provide a card pressure contact roller for a magnetic head that can easily perform a gap adjustment work between the magnetic head and the card pressure contact roller by forming the bar pressure protrusion by a diameter that is substantially smaller than that of the roller. It is a thing.

[Means for Solving the Problems]

Means adopted by the present invention to solve the above technical problems will be described below with reference to the accompanying drawings.

That is, according to the present invention, the first pressing roller (21) for pressing the magnetic track portion (c1) of the magnetic card (C) to the magnetic head (3) and the magnetic card (C) to the magnetic head (3). ) Has a second pressing roller (22) for pressing the raised magnetic bar code part (c2) on the same axis (23), and the second pressing roller (22) is more than the first pressing roller (21). The technical problem described above was solved by adopting a means of forming the bar code with a small diameter corresponding to the protrusion of the bar code.

[Action]

The card pressure contact roller for a magnetic head of the present invention comprises a second pressure contact roller (22) for contacting the magnetic bar code part (c2) of the magnetic card (C) with the magnetic head (3) and a first pressure contact roller (21).
Is formed to have a diameter that is approximately the same as that of the bar code protrusion, and is formed between the first pressure contact roller (21) and the magnetic head (3) or the second press roller (21).
The gap between the pressure contact roller (22) and the magnetic head (3) is used as a reference gap (G) for setting the gap, and the gap is set for one of the reference gaps (G).

〔Example〕

Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings.

In FIG. 1, what is designated by reference numeral (1) is a plate-shaped fixture plate vertically arranged inside the automatic ticket vending machine. A card pressure contact roller (2) according to the present invention is arranged in a bracket shape on the fixture plate (1), and a magnetic head (3) is installed below the card pressure contact roller as a micrometer. It is mounted so that it can be moved up and down by means of not shown).

In the present invention, the most important configuration is that the second pressure contact roller (22) of the card pressure contact roller (2) is replaced with the first pressure contact roller (2).
It exists in the point that it was formed in a smaller diameter than 1).

That is, in the roller of this embodiment, as shown in FIG. 1, the shaft (23) fixed to the fixture plate (1).
And the magnetic track part (c1) of the magnetic card (C) of FIG.
The first pressure contact roller (21) for contacting the magnetic head (3) with the variable information processing head portion (31) and the magnetic bar code portion (c2) of the magnetic card (C) together with the fixed information of the magnetic head (3). A second pressure roller (22) which is in pressure contact with the processing head portion (32) is rotatably fitted to each of the pressure roller (2).
1, 22) are made of a hard rubber material to prevent slippage with the magnetic card (C). The second pressure contact roller (22) is formed to have a diameter smaller than that of the first pressure contact roller (21) by a bar code protrusion (approximately 10 microns), and the second pressure contact roller (22) and the magnetic head (3). The fixed information processing head section (32) is used as a reference gap (G) for setting a gap.

When the magnetic head (3) is moved up and down to adjust the clearance between the magnetic head and the magnetic head in the roller of the present embodiment having such a configuration, the fixed information processing head section of the second pressure contact roller (22) and the magnetic head (3) ( 32) Reference gap (G)
If the gap gauge is set to a predetermined setting value,
Since the gap between the pressure contact roller (21) and the fixed information processing head (31) of the magnetic head (3) is additionally determined, the gap adjustment work for the first pressure contact roller becomes unnecessary.

Although the card pressure contact roller for a magnetic head of the present invention is constructed as described above, the present invention is not limited to the above-mentioned embodiment. For example, in the above embodiment, the first pressure contact roller (21) is used. Between the magnetic head and the variable information processing head section (31) of the magnetic head (3) is set as a reference gap (G), and the gap of the reference gap is set by a gap gauge, or the first pressure contact roller (21) and the second pressure contact roller. Needless to say, replacement of the roller (22) can be appropriately changed according to specific design requirements.

[Effect of device]

As described above with reference to the embodiments, according to the present invention, the second pressure contact roller for the magnetic bar code portion of the magnetic card is formed to have a diameter smaller than that of the first pressure contact roller for the magnetic track portion by the bar code protrusion. Since the gap between the second pressure contact roller and the magnetic head or between the first pressure contact roller and the magnetic head is set as the reference gap for setting the gap, it is only necessary to adjust the gap of one pressure contact roller. The gap of the other pressure contact roller is additionally determined, and therefore, it is not necessary to individually adjust the gap for each pressure contact roller as in the conventionally known card pressure contact roller, and the gap adjustment work with the magnetic head can be performed efficiently. It
