12 CIRCUIT DESCRIPTION
12.1. Block Diagram-1
The SOC (IC1000) controls all the system including the sensor block and the panel block.
• Screen (Film) Advance:
The SOC (IC1000) advances the screen from right to left by driving the Screen Motor after supplying the drive pulse control signal
to the Motor Driver (IC1017).
to the Motor Driver (IC1017).
• Copy Paper Advance:
The SOC (IC1000) advances the copy paper set on the Paper Cover to the output port by driving the Printer Motor after supplying
the drive pulse control signal via the Transistor Array (IC1016).
the drive pulse control signal via the Transistor Array (IC1016).
• Image processing flow:
1. Four Image Sensors from Image Sensor 0 to Image Sensor 3 are driven by the scanning control signals from the SOC
(IC1000).
2. As a result, the image analog signals are output from all four Image Sensors.
3. Next, the analog signal is converted to the digital signal by the AFE (IC1015).
4. Then, the converted digital signal is sent to the SOC (IC1000) on-chip DSP for image processing.
5. Data binarized by the DSP is stored in the SDRAM (IC1004).
6. Then the stored data is output to the built-in printer, the USB Flash Memory, and the computer by the SOC control.
