摘要：An optical information reading apparatus applies light to an object to be readsuch as a bar code symbol, photoelectrically converts by a photodetector element a lightimage formed by the reflection light, and processes the obtained electric signal tooutput code data. Among the portions performing the signal processing, at least a dataconverter (13) for converting a photoelectrically converted electric signal into a digitalsignal, a digital signal calculation unit (17) for calculating the digital signal and generatingcode 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 operationtimings of these components are arranged on a single substrate as a multipurposeprocessing circuit block (10).
