ABSTRACT:
An optical information reading apparatus applies light to an object to be read such as a bar code symbol, photoelectrically converts by a photodetector element a light image formed by the reflection light, and processes the obtained electric signal to output code data. Among the portions performing the signal processing, at least a data converter (13) for converting a photoelectrically converted electric signal into a digital signal, a digital signal calculation unit (17) for calculating the digital signal and generating code data indicating information of an object to be read, an input accumulation unit (20) for accumulating the code data, and a timing control unit (12) for controlling operation timings of these components are arranged on a single substrate as a multipurpose processing circuit block (10).
