Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prepaid card writer, and more particularly to a prepaid card writer for writing on a double-sided prepaid card.

[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. Such prepaid cards are generally printed on the surface of the prepaid card with the maximum amount, that is, the binary representation of the balance at the time of issuing the prepaid card, as a corresponding series of black circles and space data. Manufactured. Each time the prepaid card is used, the updated balance is additionally printed on the card by a card writer / writer as a data string consisting of black circles and spaces.

Further, in order to detect the occurrence of a data access error, data is printed on both sides of the prepaid card in duplicate, and test data for guiding the movement of the head during access is printed on both sides. Prepaid cards are being tried.

[0004]

[Problems to be solved by the device]

 However, there was no prepaid card writer for writing on the above-mentioned double-sided prepaid card. The present invention has been made in view of such a situation, and an object thereof is to provide a highly reliable prepaid card writer which does not accumulate an access error.

[0005]

[Means for Solving the Problems]

 The prepaid card writer of the present invention comprises two printers and a memory, has a built-in microcomputer that operates based on the means stored in the memory, and has the aforementioned means for executing the means by the microcomputer. In the stored prepaid card writer, the two printers are provided in association with each other on the front side and the back side of the loaded prepaid card, and both printers are mounted on the front side of the prepaid card. The test data and the same data are printed on the back side in a duplicated manner, and the memory has a time-division writing means for outputting the write signal to the both printers in a time-division manner, and the duplication in which the same data is knitted in duplicate. It is characterized by comprising data organization means and test data writing means for writing test data.

[0006]

[Action]

 Since the prepaid card writer of the present invention configured as described above prints the test data string on the prepaid card surface as a guide each time, for example, the position of the data string written by the prepaid card writer in the previous additional printing Even if an error occurs in the angle or the angle, there is no problem that the error in the printing position and the error in the angle are accumulated and inherited in the subsequent printing, and highly reliable writing printing with few errors can be performed. Further, since one data is printed on the front side and the back side of the prepaid card, the access error can be detected by reading and comparing the prints on the front and back of the prepaid card.

【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 writer of the present invention. FIG. 2 is an explanatory view of the front surface of the prepaid card loaded in the prepaid card writer of the present invention. Further, FIG. 3 is an explanatory diagram of the back side of the prepaid card of FIG.

First, a prepaid card loaded in the prepaid card writer of the present invention will be described with reference to FIGS. 2 and 3. The prepaid card 1 loaded in the prepaid card writer of the present invention comprises a pair of short sides 1C and 1D and a pair of long sides 1E and 1F, the short side 1C being the card front end and the front surface 1A. The back surface 1B is provided. In addition, a slit S for indicating the direction of the card is provided on the short side 1C side of the long side 1E.

On the front surface 1A and the back surface 1B, a plurality of test data formed in a row such as T1 or T2 in parallel with the short side 1C are printed at the time of data printing. The distance between the two pieces of test data is equidistant on both the front and back surfaces. Data is printed on the rear side of the card adjacent to the test data on each side. Therefore, the data mark is printed between the two test data.

Data to be recorded, for example, balance data of the prepaid card 1 is composed of, for example, eight bits D1 to D8. This balance data is printed from the long side 1F to the long side 1E as a series of black circles and spaces which are adjacent to the test data T1 on the front side 1A of the prepaid card 1 and are parallel to the short side 1C. Has been done.

Further, the same balance data is composed of 8 bits B1 to B8, and a series of black circles and spaces arranged parallel to the short side 1C on the back surface 1B of the prepaid card 1 as long spaces 1F to long sides. It is printed toward 1E. That is, the eight bits of the balance data are printed in duplicate on the front side 1A and the back side 1B of the prepaid card 1, respectively.

Next, an embodiment of the present invention will be described with reference to FIG. The prepaid card writer of the present invention comprises a set of printers 12 and 14 provided on both sides of the prepaid card 1 for printing on the front side 1A and the front side 1B of the prepaid card 1. A printer 12 having a microcomputer 5 for outputting write data to is arranged on the front side 1A side of the prepaid card 1, and a printer 14 is arranged on the back side 1B side of the prepaid card 1. And move.

The microcomputer 5 includes a CPU 6 and a memory 7. The CPU 6 executes the means stored in the memory 7 and outputs write data to the two printers 12 and 14. In the memory 7, a time-division writing means 10 for sending write signals to the two printers 12 and 14 in a time-division manner, an overlapping data organization means 11 for organizing the same data in duplicate, and test data. The writing means 8 is provided.

When the prepaid card 1 having the above-described structure is loaded in the prepaid card writer, the CPU 6 executes the test data writing means 8 and sends a signal to the printer 12 and the printer 14. Based on this signal, the printer 12 writes the test data on the front surface 1A of the prepaid card 1, and the printer 14 writes the test data on the back surface 1B. Next, the CPU 6 executes the overlapping data forming means 11 to form the same data in an overlapping manner, and then executes the time division writing means 10 to send a write signal to the two printers 12 and 14 in a time division manner. . Based on this write signal, the printer 12 writes data on the front surface 1A of the prepaid card 1 adjacent to the test data, and the printer 14 writes data on the back surface 1B adjacent to the test data. .

[0015]

[Effect of device]

 As described above, since the prepaid card writer of the present invention is configured to print the test data on each side of the prepaid card every time the data is updated and printed, there is no accumulation of error during access by the reading head. Therefore, reliable access can be realized. Furthermore, since the duplicate data structure is used, errors can be effectively detected by comparing the two at the time of access, and thus a highly reliable prepaid card system can be constructed.
