CARRIAGE UNIT OUTLINE
(PERFECTION V10 / V100 PHOTO / V200 PHOTO / V350 PHOTO)
The Carriage Unit consists of the CCD Board, Inverter Board, Lamps (light source)
and Mirror/Lens Mechanism. (Refer to Figure 2-1 and 2-2.)
 CCD Board
The Board consists of a CCD (loaded with a six-lines CCD microlens) and its
control and drive circuits.
 Inverter Board
Boosts +24VDC and converts DC to AC to generate the voltage for driving the
Lamp (white cool cathode fluorescent lamp).
 Lamps
White cool cathode fluorescent lamp (1 piece: for reflective document) is used as a
light source.
 Mirror/Lens Mechanism
The beam applied to the scanned document is reflected, passes through the Mirror/
Lens Mechanism in the Carriage Unit for correction of the beam axis, and then
reaches the CCD Sensor. The light components R, G, B are extracted by the Color
CCD Sensor itself.
