JPS5858729B2 - Magnetic card recording and playback machine - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording/playback machine using a magnetic card for personal identification.

There are various recording and reproducing machines that use magnetic cards for personal identification, such as bank cash dispensers, but in conventional magnetic card recording and reproducing machines, the insertion direction of the magnetic card is specified to be one direction. If a mistake was made, the mechanism would cause the receiver to be returned without being attached.

Therefore, there is an inconvenience in that the direction of insertion must be confirmed at the time of insertion.

This is because the magnetic recording band of a magnetic card is installed offset to one side of the card, and the reading head of a magnetic card recording/playback machine also reads the magnetic recording band only when the magnetic card is inserted in the forward direction. Something that reads memory contents 1
This is because there are only two.

The present invention was devised in view of the drawbacks of the prior art, and an object of the present invention is to provide a magnetic card recording and reproducing machine that can correctly read a magnetic card even when the card is inserted in the opposite direction.

The present invention provides two magnetic heads for reading information on a magnetic card, one for the forward direction and one for the reverse direction, and when the magnetic card is inserted in the forward direction, the information on the magnetic card is converted directly into a digital signal. If the magnetic card is inserted in the opposite direction, the information on the magnetic card is read in the reverse direction, converted to a forward direction digital signal, and then outputted. This achieves the above purpose by ensuring that it can be read correctly even if it is inserted.

The present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block diagram of a reading section of a magnetic card recording/reproducing machine showing an embodiment of the present invention, and FIG. The positional relationship between the magnetic recording strip and the magnetic head is shown. Figure 3 shows the positional relationship between the magnetic recording strip on the magnetic card and the magnetic head when the magnetic card is inserted into a magnetic card recording/reproducing machine in the opposite direction. It is something.

In these figures, 1 is a magnetic card recording/reproducing machine, 2 and 3 are magnetic heads for reading information on the magnetic card, and 2 is a forward magnetic head, and 3 is a reverse magnetic head.

4 is a forward reading unit that converts the information on the magnetic card read by the magnetic head 2 into a digital signal, and 5 is a reverse reading unit that converts the information on the magnetic card into a correct digital signal when the information on the magnetic card is read backwards by the magnetic head 3. 6 is a register that temporarily stores the information digitally converted by the backward reading section 5 and outputs it as the same digital information as the forward direction, and 7 is a register that outputs the output of this register 6 and the forward direction reading section 4.
This is a signal switching section that switches the output from.

Further, 8 is a magnetic card having a magnetic recording band 9.

In the above configuration, when the magnetic card 8 is inserted into the magnetic card recording/reproducing device 1 in the correct orientation as shown in FIG. reads the information on the magnetic recording band 9.

This information is converted into a binary digital signal by the forward reading section 4, the output path of which is selected by the signal switching section 7, and output to the next controller (not shown).

On the other hand, as shown in FIG. 3, when the magnetic card 8 is inserted into the magnetic card recording/reproducing device 1 in the opposite direction, the magnetic head 3 is placed in line with the position of the magnetic recording band 9 in the opposite direction. The information on the magnetic recording band 9 is read.

This information is converted into a binary digital signal by the reverse direction reading section 5, and is all temporarily stored in the register 6.

The accumulated information is output from the register 6 in the same order as when the magnetic card 8 is inserted in the forward direction, and the output path is selected by the signal switching unit 7 and output to the next controller (not shown). .

Therefore, even when the magnetic card 8 is inserted in the reverse direction as shown in FIG. 3, the magnetic card recording/reproducing machine operates with exactly the same output as in the forward direction.

As described above, according to the present invention, even if a magnetic card is accidentally inserted into a magnetic card recording/playing machine in the opposite direction, the information on the magnetic card can be read correctly, and the magnetic card recording/playing machine is often used. Recently, services have been improved without causing any inconvenience to magnetic card users.
