1. An optical scanning apparatus, comprising:
- communication means for receiving scan control signals from a main circuit module; and
means for generating timing control signals for extracting an analog image signal in response to the received scan control signals, wherein the timing control signals are generated at an optical sensor circuit coupled to the main circuit module via the communication means, and wherein the received scan control signals do not comprise any timing control signals.

Abstract
A scanning circuit having rearranged circuit modules at each end of a flat cable. After the rearrangement, the flat cable carries scanning control signals produced by a conventional IC communication interface instead of timing signals and carries digital image data instead of easily distorted and interfered analog image signals.
