Abstract
A bar-code reading apparatus in which a bar-code is scanned and processed for recognition of the bar-code on the basis of the scanning comprises scanning signal storage means for storing scanning signals which are obtained by scanning the bar-code and which correspond to bars and/or spaces scanned in at least two successive scannings. A counter counts the number of bars and/or spaces scanned in each scanning, while a number-of-bars storage means stores count values of the counter means in at least two successive scannings. A first comparison means compares the respective count values of the counter means in the last two scannings stored in the number-of-bars storage means with each other and generates an enabling signal when the count value in the last scanning is not larger than that in the preceding scanning. Finally, a recognition means responds to the enabling signal and operates to read the scanning signal preceding the last signal stored in the scanning signal storage means, thereby performing a process for recognizing the bar-code.
