Abstract

PURPOSE:To attain an always stable bar code decoding processing to various types of the bar code having a different reflection factor by deciding the conditions of a suitable waveform shaping from the video signal of a bar code and executing the waveform shaping processing in accordance with respective video signals. CONSTITUTION:The device is provided with a sensor 1 to light-receive a reflecting light from a bar code through an optical system, a first step amplifier circuit 2 to amplify the output of the sensor 1 and make it into a video signal, A-D converters 6 to sample the signal level of the video signal and a binarization circuit 8 to receive the output of a control means to judge the conditions to execute the waveform shaping of the video signal, waveform-shape and binarize the video signal based on the output of an A/D converter 6. A microcomputer 7 to receive the output of the circuit 8 and execute the reading processing of the bar code is provided. Thus, even when the reflection factor is largely different due to the printing condition, use environment, etc., of the bar code, the bar code can be always stably read.
