2.2 Mechanism Operation Overview

The optical system mechanism that scans the image of this scanner uses the Carriage
Unit where the light source, CCD Sensor Board, AF lens, and Mirrors move together.

2.2.1 Carriage Drive System Mechanism

The Carriage Unit slides along the Guide Rail in the sub scanning direction. To
perform this sliding operation, the CR (Carriage) Motor transmits its driving force to
the Timing Belt secured to the Carriage Unit via the Drive Pulley and Deceleration
Gear. The starting position of image data scanning is determined by the CR HP Sensor
located on the Control Board.
A stepping motor is used as the CR Motor and driven by open loop control.
