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 data
converter () for converting a photoelectrically converted electric signal into a digitalsignal, a digital signal calculation unit () for calculating the digital signal and generatingcode data indicating information of an object to be read, an input accumulation unit () foraccumulating the code data, and a timing control unit () for controlling operation timingsof these components are arranged on a single substrate as a multipurpose processingcircuit block ().
