II. OPTICAL SYSTEM
A. Outline
The optical system includes the functions of moving the scanning unit by the scanning unit
drive motor, exposing a document by the LED, and collecting the reflected light to the
phototransistor array. Contact image sensor is adopted for the scanning unit, which is a
module combined with the LED for light exposing, the rod lens array for light collecting, and
the phototransistor array for light receiving to read per line. The scanning unit drive motor
runs by the drive signal sent from the main PCB and drives the scanning unit via the drive
pulley and drive wire.
