CHAPTER 2 II. OPTICAL SYSTEM A. Outline The optical system includes the functions of moving the scanning unit by the scanning unit drive motor, exposing a document by the LED, and collecting the reflected light to the phototransistor array. Contact image sensor is adopted for the scanning unit, which is a module combined with the LED for light exposing, the rod lens array for light collecting, and the phototransistor array for light receiving to read per line.

CHAPTER 2 D. Contact Image Sensor 1. Structure of the contact image sensor Figure 2-16 shows an overview of the contact image sensor with LIDE technology. The contact image sensor has the LED for exposing a document on the end of glass part called the light conductor section. When the LED is turned ON, the LED light is supplied to the light conductor section which exposes a document. That is, the LED light indirectly exposes a document through the light conductor section.
CHAPTER 2 Figure 2-17 shows a cross-sectional view of the contact image sensor for CanoScan FB330P/FB630P, figure 2-18 shows for CanoScan FB630U/FB636U.
CHAPTER 2 The contact image sensor for CanoScan FB330P places 11 phototransistor arrays of 232 light phototransistors each in line, and the contact image sensor for CanoScan FB630P/ FB630U/FB636U place 8 phototransistor arrays of 644 light phototransistors each in line. Each phototransistor converts the received light into an image signal and outputs the data per line in series.
CHAPTER 2 D. Scanning Unit Drive Motor Control Circuit Figure 2-21 shows a block diagram of the scanning unit drive motor control circuit. The CPU analyzes each command sent from the host computer via gate array and sets to generate Pulse Motor Forward Clock (PMFCK) based on the scaling for the gate array. The gate array converts the PMFCK signals into the four phase motor drive pulse signals (PHAP, PHAN, PHBP, PHBN), which are sent to the scanning unit drive motor via the motor driver.
CHAPTER 2 III. IMAGE PROCESSING SYSTEM A. Outline Figure 2-22 shows a block diagram of the main functions of the image processing system. The image processing system converts the signals read by the contact image sensor into digital data, performs various image processing, and outputs the data to the host computer via PC port/USB port. Shading correction and gamma correction are performed by the driver software instead of the scanner function. 1. Contact image sensor 6. Packing 3. Shading correction 2.
CHAPTER 2 B. Image Processing Functions 1. Contact image sensor The CPU outputs clock signals based on the command from the host computer to the contact image sensor. The contact image sensor lights the LED in order of red, green and blue according to the clock signals, then outputs 1 line of image signal proportional to the light intensity received by the phototransistor. 2.
CHAPTER 2 5. Resolution conversion 1) Resolution conversion in the horizontal scanning direction Basic resolution of CanoScan FB330P is 300 dpi, and selective at 300 dpi, 150 dpi, 75 dpi. Basic resolution of CanoScan FB630P/FB630U/FB636U is 600 dpi, and selective at 600 dpi, 300 dpi, 150 dpi, 75 dpi. Resolution conversion in the horizontal scanning direction is performed by thinning the image data of the basic resolution. Example: To decrease the resolution to 1/2, image data is output every other pixel.
CHAPTER 2 When decreasing the resolution, the scanning unit moves at a faster speed to read less lines. Sampling point Moving direction Scanning unit Figure 2-26 6. Packing Processed image data is stored in the buffer RAM before sent to the host computer. The buffer RAM is divided into the writing block and reading block. While data is written into the writing block, the data is read from the reading block. When fixed volume has been written, the writing switches to the reading.
CHAPTER 2 Figure 2-28 shows the packing process; four 10 bits of pixels A, B, C, and D are divided into higher 2 bits and lower 8 bits, then converted into five 8 bits of image data. Lower 8 bits of pixels A to D LSB MSB A1 A2 A3 A4 A5 A6 A7 A8 B1 B2 B3 B4 B5 B6 B7 B8 C1 C2 C3 C4 C5 C6 C7 C8 D1 D2 D3 D4 D5 D6 D7 D8 Higher 2 bits of pixels A to D A9 A 10 B9 B 10 C9 C 10 D9 D 10 E1 E2 E3 E4 E5 E6 E7 E8 ......

CHAPTER 2 IV. CONTROL SYSTEM A. CanoScan FB330P/FB630P 1. Outline CanoScan FB330P/FB630P control system consists of the CPU and gate array. The CPU has 7 digital ports. P0, P2, P3, P6, and P7 are for generating control signals in the main PCB. P4 is for address bus and data bus (AD-AD7) and P5 is for address bus (A8-A15). P7 is mainly for inputting a function check mode setting. CPU P5 A8~15 Control signal P0, P2, P3, P6, P7 P4 AD0~7 Gate Array To host computer Figure 2-29 2.
CHAPTER 2 When the scanner is ON, parallel port signals are directly sent to the printer, meanwhile the scanner monitors the command sent from the host computer. Host Scanner computer Printer Monitors the command Figure 2-31 When the host computer sends the signal to start the communication with the scanner, the scanner disconnects the control line from the host computer to the printer, meanwhile the signal sent from the host computer to the printer is ignored.
CHAPTER 2 B. CanoScan FB630U/FB636U 1. Outline CanoScan FB630U/FB636U is not equipped with the CPU and the scanner is controlled by the device driver installed in the host computer. The device driver includes the scanner control program, which sets a command directly to the gate array register to control the scanner. 2. Outline of USB CanoScan FB630U/FB636U is connected to the host computer via USB interface.
CHAPTER 2 USB connector has A plug for connecting to upper layer and B plug for connecting to lower layer. A Plug B Plug Figure 2-34 3) USB data transfer USB data is transferred in the following 4 data structures called "packet".
CHAPTER 2 V. POWER SUPPLY A. CanoScan FB330P/FB630P AC adapter is adopted for the CanoScan FB330P/FB630P power source. The AC adapter converts the AC power into +10.5 VDC. The output DC power is converted into +5 VDC in the main PCB. +5 VDC is used for the IC in the main PCB, the scanning unit drive motor and the contact image sensor. The scanner has an overvoltage detection function to check if an AC adapter for other scanner is connected and overvoltage is input.
CHAPTER 2 B. CanoScan FB630U/FB636U CanoScan FB630U/FB636U draws its power +5 VDC from USB interface. +5 VDC is used for the IC in the main PCB, the scanning unit drive motor and the contact image sensor.
