Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prepaid card type determination mechanism capable of determining a prepaid card type.

[0002]

[Prior art]

 Conventionally, for the purpose of preventing data tampering and fraud, a prepaid card with a structure in which the balance is printed and displayed as a binary data with a gray mark on the surface of a paper or plastic card and the display is updated each time the balance is updated is used. Has reached the end. Generally, several types of such prepaid cards are issued, such as 5,000 yen cards, 3,000 yen cards, and 1,000 yen cards, with different attributes such as the maximum usage limit. is there. However, unlike a bill, etc., such a prepaid card does not change the size of the medium according to the attribute.For example, the 5,000 yen card and the 1,000 yen card have exactly the same size and shape. In order to prevent fraud such as rewriting the balance of a small amount of card, the prepaid card has two type marks on one long side of the prepaid card, separated by different distances for each card type. The card is about to be tried.

[0003]

[Problems to be solved by the device]

 However, there is no prepaid card type determination mechanism for detecting the type of prepaid card as described above. The present invention has been made in view of such circumstances, and an object thereof is to provide a prepaid card type determination mechanism capable of automatically and quickly determining the card type.

[0004]

[Means for Solving the Problems]

 The prepaid card type determination mechanism of the present invention is a prepaid card having two type marks spaced apart from each other on a side thereof and incorporated into a prepaid card reader / writer that moves inward. A reflected light type optical sensor for detecting the type mark provided, a light source for sending light to the reflected light type optical sensor, a trigger type flip-flop triggered by a signal from the reflected light type optical sensor, and a clock. It is characterized by comprising a generator, an AND circuit of the output of the clock generator and the output of the trigger flip-flop, and a binary counter which counts based on the output of the AND circuit.

[0005]

[Action]

 In the prepaid card type determination mechanism of the present invention configured as described above, the type mark detection means detects each of the two type marks provided on the sides of the prepaid card passing at a constant speed after a certain period of time. Then, the trigger type flip-flop is turned on / off by these two detection signals to detect and output the elapsed time. Based on this elapsed time, the type of inserted card can be determined.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram of an embodiment of the prepaid card type determination mechanism of the present invention. 2 is an explanatory view of a prepaid card loaded in the prepaid card type determination mechanism of the present invention.

First, referring to FIG. 2, a prepaid card loaded in the prepaid card type determination mechanism of the present invention will be described. The prepaid card P loaded in the prepaid card type determination mechanism of the present invention has a configuration in which two type marks S1 and S2 are provided on one of the long sides at different distances for each card type. ing.

Next, an embodiment of the present invention will be described with reference to FIG. The prepaid card type determination mechanism 1 of the present invention is incorporated in a prepaid card reader / writer (not shown) and determines the card type when the prepaid card P having the above-mentioned configuration is inserted. In the prepaid card type determination mechanism 1, a reflected light type optical sensor 2 for detecting the type marks S1 and S2 provided on the long side of the prepaid card P moving inside is provided in the traveling path of the prepaid card P. ing.

The prepaid card type determination mechanism 1 includes a trigger type flip-flop 3 triggered by a signal from the reflected light type optical sensor 2, a clock generator 4, an output of the clock generator 4 and a trigger type flip-flop 3. The output AND circuit 5 and the binary counter 6 for counting based on the output of the AND circuit 5 are provided.

When the prepaid card P having the above-mentioned configuration is loaded on the prepaid card type determination mechanism 1 and the first type mark S1 reaches the reflected light type optical sensor 2, a detection signal is generated. At the rising edge of this detection signal, the trigger flip-flop 3 whose output was low level is triggered and the output becomes high level, the clock pulse from the clock generator 4 passes through the AND circuit 5, and the binary counter 6 Is counted.

When the type mark S2 reaches the reflected light type optical sensor 2 and the detection signal rises in the same way, the trigger type flip-flop 3 is retriggered to bring the output to a low level and the clock generator 4 outputs the signal. The clock pulse is cut off by the AND circuit 5. Therefore, the counting of the binary counter 6 also stops here. As described above, when the card types are different, the distance between the two type marks S1 and S2 is different, and the elapsed time required to move by this distance is also different. Since the difference between the elapsed times appears in the count difference of the binary counter 6, this count difference is used to determine the card type.

[0012]

[Effect of device]

 As described above, the prepaid card type determination mechanism of the present invention determines the card type by using the difference in the elapsed time required to move the distance between the two type marks S1 and S2 of the prepaid card. Therefore, the card type can be automatically determined in the process of moving the prepaid card to be loaded on the read / write head, and thus the card type can be quickly determined without any loss of determination time.
