In the embodiment, such a magnetic display card 2 is described as an example, but the magnetic recording unit 4 and the magnetic recording unit 6 may be arranged on one side.

The direction discriminating mechanism is provided with a transfer path 8 for transferring the magnetic display card 2, and a transfer mechanism 10 is provided as means for transferring the magnetic display card 2 on the transfer path 8. There is. The transfer mechanism 10 is composed of a plurality of rollers for transferring the magnetic display card 2 while elastically holding it. The moving mechanism 10 is controlled by a control output from a control device 12 that performs various controls such as magnetic erasing and transfer of the magnetic display card 2.

A position sensor 16 as a first detecting means for detecting the insertion of the magnetic display card 2 is installed at the insertion / ejection port 14 of the transfer path 8, and the insertion direction of the magnetic display card 2 is set to a magnetic field. Magnetic recording unit 6 of display card 2
A direction discriminating sensor 18 is installed as a second detecting means for detecting the contrast from the other portions. The detection outputs of the position sensor 16 and the direction determination sensor 18 are added to the control device 12 as direction determination means as direction determination information.

A shutter 20 is installed on the transfer path 8 as a blocking means for passing or blocking the magnetic display card 2 depending on the inserting direction of the magnetic display card 2. The shutter 20 permits or prohibits the movement of the magnetic display card 2. It is a mechanical mechanism and is driven by a drive mechanism 22. This drive mechanism 22
Is a device for generating a mechanical force by an electric driving force of a solenoid or the like, and its operation is controlled by the control output of the control device 12.

The control device 12 is composed of a data processing device such as a microcomputer, and includes the magnetic display card 2.
Various controls such as transfer control of the magnetic disk, direction determination operation of the magnetic display card 2, drive control of the shutter 20, and the like.

The direction discriminating mechanism is provided with a display device 26 which receives a display output as the direction discriminating output of the control device 12 and indicates whether or not the inserting direction of the magnetic display card 2 is proper. The display device 26 includes a light emitting element such as an LED,
It can be configured by an optical display element of an LCD display, a buzzer that acoustically issues a warning, a voice display element that notifies the direction by voice, or the like.

The transfer path 8 is provided with a reading / writing device 24 for reading data from the magnetic recording section 6 of the magnetic display card 2 which has passed through the shutter 20 and writing necessary information in the magnetic recording section 6. There is. Further, although not shown, a print head or the like for writing necessary character information and the like is provided on the magnetic display unit 4.

Next, the principle of discriminating the direction of the magnetic display card 2 will be described with reference to FIG. (A) shows the magnetic display part 4 side of the magnetic display card 2, (B) shows the magnetic recording part 6 side, respectively, and (A) and (B) are the front and back relations, respectively. In such a magnetic display card 2, when the areas a, b, c, d at the corners of the magnetic display card 2 of (A) are compared, the areas a, b, c, d are the detection units of the direction determination sensor 18. The magnetic recording part 6 is present in the area c, and is compared with other areas a, b and d.
It can be seen that a strong contrast is obtained by the magnetic recording unit 6. The example, each area a, b, assuming lightness from the magnetic recording portion 6 d and the small area c _O is to set bright colors, for example white, only the area c becomes two colors of black and white, the area c Can be clearly distinguished from the other areas a, b and d by the color and their color arrangement.

Therefore, if the direction discriminating sensor 18 is composed of a pair of sensors for detecting the magnetic recording portion 6 of the area c and the small area c _O , that is, a black / white sensor, the direction of the magnetic display card 2 is this direction. The presence of the magnetic recording portion 6 makes it possible to obtain a detection output indicating the direction. Of course, since the magnetic recording portion 6 has a color characteristic, the direction determining sensor 18 may detect the magnetic recording portion 6 independently.

Next, the direction determining operation will be described with reference to FIG. In step S1, the magnetic display card 2 is inserted, and the discriminating operation is started by this insertion. Step S
In 2, the insertion of the magnetic display card 2 is detected by the position sensor 16. In step S2, if the direction determining operation is not performed despite the magnetic display card 2 being inserted, it is determined that the magnetic display card 2 is damaged as shown in step S3.

Next, in step S4, the direction discrimination sensor 1
Based on 8, it is determined whether or not the inserting direction of the magnetic display card 2 is proper. This determination is based on the detection output of the position sensor 16, and is determined by the detection output of the direction determination sensor 18,
The principle of the discrimination is that the direction is discriminated by a detection output based on the presence / absence of the magnetic recording unit 6 of the magnetic display card 2 using a black / white sensor. As a result, if the insertion direction is incorrect, the process proceeds to step S5 and the display is performed.
This display is performed by lighting a lamp or the like or by sound.

If the magnetic display card 2 is inserted in the proper direction, the process proceeds to step S6 and the shutter 20
And the magnetic display card 2 is introduced into the transfer path 8 by the transfer mechanism 10.

Next, in step S7, the reading / writing device 24 reads data from the magnetic recording section 6 and writes data in the magnetic recording section 6 on the transfer path 8.
In this case, magnetic display according to the updated data is performed on the magnetic display unit 4.

In this way, the magnetic display card 2 is transferred based on the judgment as to whether the insertion direction of the magnetic display card 2 is proper,
As a result of the interruption, the reliability of reading or writing data to the magnetic display card 2 can be improved, and the read / write device of the magnetic display card 2 and the magnetic display card issuing machine can be prevented from malfunctioning. The read / write device and magnetic display card issuing machine can be protected from damage due to improper insertion.
