The scanning block of this device consists of a control circuit and a CIS (contact image sensor), and AFE (Analog Front End)
include A/D Converter.
include A/D Converter.
When start the scanning, pin D12 of IC300 will be low level and the transistor Q518 turns on, 3.3V is supplied to the CIS.
The CIS is driven by each of the signals (CCDSH, CCDCLK) which are output from IC300.
The analog image signal is input to the AFE (20pin of IC503), and converted into 16-bit data by the A/D converter inside.
Then this signal undergoes digital processing in order to obtain a high-quality image in IC300.
