Abstract

PURPOSE: To provide a charge detection function to reduce the number of used articles by detecting that the maximum value of analogue electric signals obtained by subjecting the reflection light of a scanning light to photoelectric conversion exceeds a prescribed value.
CONSTITUTION: When object 6 where bar-code label 7 is stuck comes to the front of detection part 1, the reflection light of scanning light 8 becomes intense because of reflection on object 6. Consequently, analogue electric signals of the output of detection part 1 are strong and are larger than reference voltage 10, so that comparator 9 may generate pulses. These intermittent pulses are made continuous by monostable multivibrator 11. By these continuous signals, a bar-code reader completes read preparation, and output analogue electric signals of detection part 1 are converted to digital electric signals by converter circuit 2 and are decoded by decoder 3, and information of bar-code label 7 is made into a fixed code and is read.
