Figure 2-3-7 CCD PCB block diagram
The clock signals SHIFT, CLP, RS and CLK from the clock signal generator on the
scanner control PCB (SCPCB) are sent to the CCD PCB (CCDPCB), where clock driver
IC3 generates eleven clock signals to drive CCD IC1. Upon reception of clock signals,
the CCD IC1 outputs analog image signals according to the density of the image. Even-
and odd-numbered pixels are output separately. These analog image signals are
amplified by the operational amplifier IC2 via the emitter followers TR1 and TR2, and
then sent to the image processor of the scanner control PCB (SCPCB).
