Abstract

PURPOSE:To ensure an automatic and effective recognition of characters for an inspection of characters on an automatic assembly line of an electronic calculator, by compressing the character pattern information of the displayed characters and thus recognizing the displayed characters. CONSTITUTION:For a head leading process out of the memory CM, the contents of the memory PM is called out to detect the position of the display information on the pattern memory PM that stores the pattern information of the display part of an electronic calculator that received a photoelectric conversion. Then the display information of a character is compressed to an information of e.g. 7 bits based on the mask pattern information that is read out of the memory PM and stored previously into the memory CM. This compression data is compared with the standard pattern information of 8 bits and stored in the memory CM. If the recognized character is defective, the relevant electronic calculator is excluded by the defective product exhausting device NE. In case no defect is detected, the relevant calculator is passed. In such way, an automatic and effective recognition is possible for the characters.
