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. To prevent fraud such as rewriting the balance of a small amount of card, the prepaid card has two slits 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 slits provided on its sides at a distance from each other, and is incorporated in a prepaid card reader / writer that moves inward. A transmission type optical sensor provided for detecting the slit, a light source for transmitting light to the transmission type optical sensor, a trigger type flip-flop triggered by a signal from the transmission type optical sensor, and a clock generation. , An AND circuit of the output of the clock generator and the output of the trigger type flip-flop, and a binary counter that 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 slit detection means detects each of the two slits provided on the side of the prepaid card passing at a constant speed with a certain time, The trigger type flip-flop is turned on / off by these two detection signals to detect and output the elapsed time. The type of inserted card can be determined based on this elapsed time.

[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 structure in which two slits 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 transmissive optical sensor 2 for detecting slits S1 and S2 provided on the long side of the prepaid card P moving inside is arranged in the traveling path of the prepaid card P. Light is transmitted from the light source 10 which is arranged with the prepaid card P interposed therebetween to the transmissive optical sensor 2.

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

When the prepaid card P having the above-described structure is loaded on the prepaid card type determination mechanism 1 and the tip of the card reaches the transmissive optical sensor 2, the light from the light source 10 is blocked and the detection signal is interrupted. Eventually, when the first slit S1 reaches the transmissive optical sensor 2, the light from the light source 10 is transmitted and enters the transmissive optical sensor 2, and the detection signal recovers for a while. The light from is blocked and the detection signal is lost. At the falling 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 by.

When the slit S2 reaches the transmissive optical sensor 2 and passes therethrough, and a detection signal falls similarly, the trigger type flip-flop 3 is re-triggered and the output becomes low level. The clock pulse from 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 type is different, the distance between the two slits S1 and S2 is different, and the elapsed time required to move by this distance is also different. Since this difference in elapsed time appears in the count difference of the binary counter 6, the card type is determined using this count difference.

[0012]

[Effect of device]

 As described above, the prepaid card type determination mechanism of the present invention is configured to determine the card type by using the difference in the elapsed time required to move the distance between the two slits S1 and S2 of the prepaid card. Therefore, the card type can be automatically determined in the process of moving the prepaid card so as to be loaded in the read / write head, and thus a quick card type determination with no loss of determination time can be realized.
