Scanning Block
The scanning block of this device consists of a control circuit and a contact image sensor made up of a celfoc lens array, a light
source, and photoelectric conversion elements.
When an original document is inserted and the start button pressed, pin 129 of IC1 goes to a high level and the transistor Q14 turns
on.This applies voltage to the light source to light it. The contact image sensor is driven by each of the FTG-F1 signals output from
IC1, and the original image illuminated by the light source undergoes photoelectric conversion to output an analogue image signal
(AIN). The analogue image signal is input to the system ASIC on AIN1 (pin 3 of IC1) and converted into 8-bit data by the A/D con-
verter inside IC1. Then this signal undergoes digital processing in order to obtain a high-quality image.
