Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prepaid card which enables accurate reading of graphic data code information recorded on the prepaid card.

[0002]

[Prior art]

 Conventionally, a two-dimensional recording code such as a figure data code is read by moving the code reading sensor at a predetermined standard speed and moving the speed at a constant speed as much as possible. Here, the code reading sensor is a system in which a slit having a predetermined width is moved in the recording forward direction on the white / black pattern graphic data of bit information, light is incident on the slit, and reflected light is detected. Therefore, if the moving speed of the code reading sensor during reading of the two-dimensional recording code changes from the predetermined standard speed, that is, if the moving speed is too high, the white / black graphic code is recorded by the code reading sensor. The reading time of the width changes, and the reliability of the reading result of the two-dimensional recording code such as the data code read by erroneously determining “1” as “0” without exceeding the predetermined threshold value is impaired. .

[0003]

[Problems to be solved by the device]

 In the conventional reading of the two-dimensional recording code, the moving speed of the code reading sensor during reading the two-dimensional recording code is configured to minimize the speed change, as described above. There was a problem due to the high cost.

An object of the present invention is to provide a prepaid card which is provided with a pattern for controlling the feed motor and which can improve reliability in reading information recorded on the card. is there.

[0005]

Means for Solving the Problems The prepaid card according to the present invention is a black and white in which one unit data code is used for n (n is an integer of 2 or more) segments, and each segment is associated with bit information 1/0. A prepaid card in which a pattern / black-and-white pattern figure is formed and a 1-unit data code is formed by those segment matrices, and the prepaid card is recorded at a predetermined speed along the segment row direction of the recorded pattern figure of the bit information. A periodic signal graphic pattern that serves as a reference for moving the reading sensor is recorded when the prepaid card is issued, or a recording area prerecorded on the surface of the prepaid card is provided, and the periodic signal read from the recording area is recorded. Based on this, it controls the moving speed of the reading sensor when reading the bit information. To.

[0006]

[Action]

 The prepaid card according to the present invention has a graphic pattern for reading information recorded on the prepaid card while keeping the bit rate of the two-dimensional graphic data code recorded on the prepaid card constant at an optimum predetermined standard speed. When the pre-paid card is issued, or when the two-dimensional graphic data code of the pre-paid card is read in advance, when the pre-paid card is issued, the reference periodic pattern represented by is recorded in the recording area at the predetermined position. Since the bit information recorded on the prepaid card is read by controlling the movement based on the periodic signal detected from the periodic pattern read from the recording area, accurate information reading is performed for each prepaid card. .

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, a prepaid card 1 in which the two-dimensional code shown in FIG. 1 is recorded is shown. FIG. 1 shows a prepaid card of the present embodiment. In FIG. 1, 1a is an initial code area of the prepaid card 1, and an initially set amount, a store name, a date information code of 1b is a balance code area. Yes, it is the amount information code of the used amount, store name, and date. Here, the code of each segment is recorded as "1" as a black and white pattern and "0" as a black and white pattern. Therefore, even if "0" or "1" continues, the frequency component of the output signal from the read sensor that moves on the segment surface at a constant speed is included in the narrow frequency band. Reference numeral 2 is a recording code in which black and white patterns for controlling the feed speed when moving the reading sensor are one-dimensionally arranged in a recording area at a predetermined position in the recording direction. FIG. 2A is a pattern configuration diagram showing the configuration of the recording code 2 in the recording area for controlling the feed speed recorded on the prepaid card 1 of this embodiment. Here, 3 is bit information in which “1” is represented by a black pattern and 4 is “0” by a white pattern, which is displayed by a predetermined number of bits. The recording code 2 representing the predetermined number of bits "1" or "0" is recorded when the prepaid card is issued or recorded in the prepaid card 1 in advance. The read cycle T of "1" and "0" of the recording code 2 is used for sensor movement control when reading the initial code area 1a and the balance code area 1b. FIG. 6B shows the output waveform when the recording code 2 is first read by the sensor, that is, the basic period T for sensor movement control.

Next, the operation will be described. The feed speed by the feed motor that moves the reading sensor in the segment recording forward direction of the figure recording code of the prepaid card starts from the reading of the recording code 2 at a predetermined standard speed at the very beginning. The sensor is first sent at this feed speed to read the recording code 2 of the prepaid card 1. Then, the period T read from the recording code 2 is stored in the storage unit of the system control unit that controls reading.

Next, the reading sensor is moved in the order of recording in the order of the initial code area 1a and the balance code area 1b of the prepaid card 1, and the reading is continued at the predetermined standard speed. During this period, the system control section always compares the cycle T read from the recording code 2 stored in the storage section.

That is, from the frequency component included in the data code signal read by the reading sensor such as the initial code area 1a and the remaining code area 1b, a black and white pattern corresponding to “1” of the bit information or a black and white corresponding to “0”. The cycle of passing through the pattern segment is detected, and if the cycle becomes smaller than the cycle T of the storage section, the feed motor speed is slowed, and if the cycle becomes larger than the cycle T of the storage section, the feed motor is made faster To control the feed motor.

By controlling as described above, the feed motor is controlled so as to match the cycle T read from the recording code 2, and the reading sensor can be moved at a constant standard speed to improve reliability.

It should be noted that in the above-described embodiment, the recording code 2 is processed in an analog manner to control the sensor feed speed to an optimum constant speed, but by digitally processing it, the prepaid card is processed. The feed speed may be controlled to an optimum constant speed. In this case, the feed rate information indicating the optimum feed rate for the prepaid card is written in the recording code 2 as a code, and the feed rate information is automatically determined from this code.

[0013]

[Effect of device]

 As described above, according to the present invention, the recording code of bit information represented by a black-and-white pattern for controlling the feed speed of the reading sensor when reading the information recorded on the prepaid card is stored in the predetermined recording area of the prepaid card. Since the information is recorded in the pre-paid card, the information can be accurately read for each prepaid card, and the reliability of the reading sensor can be improved.
