Abstract

PURPOSE:To simplify the constitution of an optical system, by deciding the validity of data from the identity of the contents of read results obtained by the several times of scanning of a bar code total image stored in an image memory by a program at different positions in a memory. CONSTITUTION:The bar code total image binarized by reading a bar code 12 optically is stored in the image memory 17, and bar code data can be obtained scanned for several times by scanning the bar code total image stored in the image memory 17 by a scanning and reading means 13 at decided plural positions. And the validity of the data is judged from the presence/absence of the identity of the content of the bar code scanned for several times at each position by a data validity decision means 15. In such a way, it is possible to detect the content of the bar code 12 accurately without being conscious of the simplification of the constitution and the installed position of the optical system especially.
