Abstract:
An optical code reading process and a reading stability determining process are performed while suppressing an increase in the cost of a transfer system and avoiding a decrease in work efficiency. CMOS performs imaging. Processor reads an optical code contained in image data taken by CMOS and outputs a signal upon success of reading of the optical code. Further, processor calculates a first contrast at the time of teaching and a second contrast at the time of reading success, and determines reading stability based on a decrease rate of the second contrast with respect to the first contrast.

Claim (Index 6):
An optical information reading apparatus, comprising:\n an imaging section that performs imaging to obtain image data; and a control section that decodes binarized data of an optical code contained in the image data taken by the imaging section to obtain code information and outputs a signal upon success of reading of the optical code, wherein the control section:\n converts the code information back to binarized data of the optical code, \n counts the number of erroneous dots through binarization determination by comparing the binarized data of the optical code contained in the image data and the binarized data of the optical code obtained by converting the code information, \n calculates a damage rate that is a ratio of the number of erroneous dots counted through binarization determination to the total number of dots of the entire optical code, and \n determines reading stability on the basis of the damage rate.
