2.3.2.4 Mirror Carriage A and Mirror Carriage B Moving Mechanism
<Mirror Carriage Ar>
During a scan, the Mirror Carriage A projects an even amount of light from the Exposure Lamp onto the
entire surface of the original. The light is reflected from the original to the Mirror A of the Mirror Carriage
A and then to the Mirror B and Mirror C of the Mirrors Carriage B.
The Mirror Carriage A is driven by the FBS Motor and front and rear Scanner Drive belts.
Scanner speed is determined by the set zoom ratio in reference to the full size mode.
The Mirror Carriage A is at home position when Scanner Home Position Sensor is blocked. This position
serves as the reference for the scan motion.
The A4 sensor and B4 sensor restricts the movement of the Mirror carriage A according to the original
document size.
<Mirrors Carriage B>
The Mirror B and Mirror C are mounted to their holder at right angles to each other. They direct the light
reflected off the Mirror A through the lens to the CCD.
The Mirror Carriage B is also moved by the Scanner Drive belts and pulleys driven by the FBS Motor. It
travels at a speed half that of the Mirror Carriage A, thereby keeping constant the optical path length
between the Original Glass and lens.
