5)Driving the optics unit
•
The optics unit (full-speed and half speed unit) is driven by the optics unit motor.
Its rotation is transmitted to the full-speed and half-speed unit via optics drive belt,
optics drive pulley, full-speed unit drive wire and half-speed unit drive wire.
•
Regarding the optics drive pulley, the diameter of the half-speed unit pulley is 1/2
of that of the full-speed unit pulley. Therefore, the half-speed unit moves at 1/2
speed of the full-speed unit and this mechanism makes it possible to keep the
optical path length constant between the original and lens.
•
The fixed position of the full-speed unit is determined by the full-speed unit position
detecting plate and the optics unit home position sensor.
•
The full-speed unit has the exposure lamp and no.1 mirror. It scans the original
with the exposure lamp and guide the reflection via no.1 mirror to the no.2 and
no.3 mirrors. The image is formed on the CCD image sensor via lens.
