Abstract
In a bar-code generally number of modules corresponding to each character is seven. However, if the number of modules judged from the data obtained by reading a bar code is, for example, six, the character is demodulated using a demodulation-pattern table corresponding to six modules.
Claims8
A bar-code reader comprising:
- a judging unit that judges number of modules corresponding to a character from character data read from a bar-code;
- and
- a demodulating unit that, if the number of modules judged is different from a predetermined number, demodulates the character by using a demodulation-pattern table corresponding to the number of modules judged.
A method of reading a bar-code, comprising:
- judging number of modules corresponding to a character from character data read from the bar-code;
- and
- if the number of modules judged is different from a predetermined number, demodulating the character by using a demodulation-pattern table corresponding to the number of modules judged.
