The CCD PCB (CCDPCB) receives clock signals
φ
SHIFT,
φ
CLK,
φ
RS,
φ
CLP and
generate eleven signals based on those clock signals necessary to drive the CCD IC1.
When clock signals are input, the CCD IC1 outputs analog signals which are divided
into even pixel signals and odd pixel signals depending on the set density of the image,
which are transmitted to the main PCB (MPCB) via the emitter follower circuit and
differential amplifiers IC4 and IC5.
