CARRIAGE UNIT MECHANISM
(PERFECTION V10 / V100 PHOTO / V200 PHOTO / V350 PHOTO)
The scanning of an image on document is carried out with the combination of the main
scanning direction (one line: CCD Sensor) and sub scanning direction (multiple lines:
Carriage Unit movement).
The line type color CCD Sensor can only scan one line in the main scanning direction
(in parallel with the Carriage Unit) at one time. To scan the second and latter lines in
the sub scanning direction, the Carriage Unit having a built-in CCD Sensor is moved
by CR drive. The scanned data are sent to the Control Board. The scanning of Line n
data and the processing of Line n-1 image data are performed consecutively at the same
time.
Figure 2-5. Carriage Movement
The Carriage Unit slides in the sub scanning direction by the CR Timing Belt Motor,
which is powered by the transmitted force from the CR Motor as shown below. The CR
Motor is a stepping motor and is driven under open loop control. The starting location
for scanning an image is determined by the CR HP Sensor which is located on the
Control Board.
