Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a printing device for printing information such as the number of times a magnetic card has been used on a magnetic card.

[Conventional technology]

Conventionally, when a magnetic card is issued, the expiry date, name, number, and usage frequency by the user after issuance are printed on the card surface each time the card is issued. Especially in the latter case, the printing timing is, for example, printed on the card surface. Positioning has been done using the output signal of an encoder that is a combination of a slit plate and optical sensor fixed to the feed roller shaft, or by supplying pulse signals to a pulse motor, but installing a slit plate requires space. Slit plates have the disadvantage of being relatively expensive. The use of a pulse motor also has the disadvantage of being expensive.

[Purpose of invention]

In view of the above drawbacks, the present invention proposes a printing device that uses a magnetic signal for recording and reading magnetically recorded information recorded on a magnetic card as a printing timing signal, eliminating the need for an encoder or pulse motor. .

[Structure of the idea]

The present invention resides in printing on the magnetic card using a magnetic signal recorded on the magnetic stripe of the magnetic card as a printing timing signal.

〔Example〕

Hereinafter, the present invention will be explained with reference to an illustrated embodiment. In FIGS. 1 to 3, a printing device 1 is a magnetic head 3 that reads the record of a magnetic card 2 on which magnetic signals are recorded.
a dot printer 4 having a plurality of wires, an amplifier 5 for amplifying the magnetic signal, a demodulator 6, and a computer 7 for generating a print clock signal from the magnetic signal and inputting a print position signal and print information of symbols or characters for control. and a printer drive section 8.

A magnetic stripe 9 is provided on the surface of the magnetic card 2.
and a thermal transfer processing surface 10 are provided.

When printing on the magnetic card 2, a print position signal and a print information signal of symbols or characters are input to the computer 7, and the magnetic card 2 is placed on the standard surface 11 of the card running path of the magnetic card reproducing device provided with the printing device 1. The magnetic head 3 reads the magnetic signal, and the demodulator 6 outputs the read data A and read clock signal B shown in FIG. The computer 7 generates a print clock signal C that uses bits and characters as printing information for the dot printer 4, and the computer 7 sends the print clock signal C to the printer drive section 8 as a timing signal for printing. C and the print position information signal, the symbol or character print information signals D ₁ , D ₂ , D ₃ , ...D _i , ...D _o are input to the drive coil 13 of the wire 12 of the dot printer 4, and the plurality of wires 12 are input. By driving, printing is performed on the thermal transfer processing surface 10 of the magnetic card 2.

When the usage frequency of the card is used in the printed information signal, symbols and characters corresponding to the usage frequency are printed.

As mentioned above, the magnetic stripe 9 of the magnetic card 2
If the magnetic signal recorded in the magnetic signal is used as the timing signal for printing, the encoder and pulse motor are not required, and the printing device 1 can be made smaller and the cost can be reduced.

In the above description, the read data signal A and the read clock signal B are input to the computer 7 to control the printer drive unit 8, but they may be input directly to the printer drive unit 8 without going through the computer 7.

[Effect of idea]

Since the present invention is configured as described above, the magnetic signal recorded on the magnetic stripe can be used as a timing signal for printing in a dot printer, so an encoder and a pulse motor are not required, and the printing device can be made smaller and costs can be reduced. It is possible to provide a printing device that has excellent practical effects such as the ability to
