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.
Claims10
A scanning circuit for a document scanner, comprising:
- a main circuit module for receiving a scanning instruction from a communication interface, converting the scanning instruction into scan control signals, passing the scan control signals to a connection cable as well as receiving a digital image data captured in a document scanning operation through the connection cable;
- and
- an optical sensor circuit module connected to the main circuit module through the connection cable for receiving the scan control signals and converting the scan control signals to timing control signals that control document scanning, extraction of an analog image signal from the document and conversion of the analog image signal into the digital image data.
