Abstract:
1. A scanning apparatus having a chassis and a main board, wherein the chassis is connected to the main board for performing a scanning operation, the scanmng apparatus comprising: a charge-coupled device (CCD) module, disposed on the chassis for sensing a light analog signal; a front end processing device, disposed on the chassis and electrically coupled to the charge-coupled device module, the front end processing device comprising: an analog front end processor, electrically coupled to the charge-coupled device module for converting the light analog signal to a light digital signal; and a signal generator, electrically coupled to the charge-coupled device module and the analog front end processor, for generating a control signal corresponding to operation of the charge-coupled device module and the analog front end processor; and an application-specific integrated circuit (ASIC), disposed on the main board and communicating with the front end processing device through a command interface for processing the light digital signal transmitted from the analog front end processor of the front end processing device.
