  • Page 34: Operating Principles

    OPERATING PRINCIPLES 2.1 ENGINE OPERATION This section describes the functions and operating principles of the FilmScan 200 engine. The engine contains a CCD image sensor with a reading resolution of 1200 dpi. The engine consists of two main sections: the scanner head and the carriage movement mechanism.

  • Page 35: Photosensitive Section

    FilmScan 200 2.1.1.1 Photosensitive Section The photosensitive section converts the light energy into electrical signals and accumulates the resulting signal charge over a short term. The description below explains the process of photo electrical conversion to change the incoming light energy into accumulated signal charge. Refer to Figure 2-3.

  • Page 36: Transmission Section

    OPERATING PRINCIPLES 2.1.1.2 Transmission Section This section receives the signal charge from the photo-sensitive section and transfers it to the output section.

  • Page 37: Carriage Operation

    FilmScan 200 2.1.2 Carriage Operation Because photo-sensor elements are aligned and have a one-to-one correspondence with a horizontal row of pixels, no mechanical operation is required for the main scan (one horizontal reading of the original film). To read more than a single line, however, vertical movement (sub-scanning) is also necessary. This requires mechanical movement of the scanner head.

  • Page 38: Film Carrier Main Scanning

    OPERATING PRINCIPLES 2.1.2.2 Film Carrier Main Scanning The film carrier is stored on the carrier holder unit. At the main scanning, the main scan motor where on the bottom of the optical unit drives carrier holder unit via reduction gear, then the carrier holder unit moves forward and backward and the main scanning is done.
  • Page 39 FilmScan 200 2.1.3 Film Carrier or APS Holder Selection The scanner is available to load either the film carrier for 35 mm film or the APS holder for APS negative film cartridge. 2.1.3.1 Front Panel Unit Face Change The front panel unit has two different faces by the positioning of the cover (Refer to Figures 2-10 and 2- 11.).
  • Page 40 OPERATING PRINCIPLES 2.1.3.2 Electric Terminal linkage (When APS Holder is installed) The APS holder contains film wind/rewind motor, photo sensor, and their control and drive circuit. When the APS holder is installed to the scanner, the micro switch A detects the APS holder and the four signal terminals at the right corner of APS holder contact to the electric terminal of carrier holder unit and then it is possible to communicate with the scanner.

  • Page 41: Power Supply Operation

    FilmScan 200 2.2 POWER SUPPLY OPERATION The scanner can be powered by either of two power supply boards: the 100-120 V AC power supply board or 220-240 VDC power supply board. The Only difference in the way these boards operate is in the primary circuitry.

  • Page 42: Circuit Operation

    OPERATING PRINCIPLES 2.2.2 Circuit Operation Figure 2-13 shows the power supply circuitry in block diagram form. AC power feeds into the scanner from the external power source. A filter circuit removes the noise. The AC voltage then undergoes full-wave rectification and is smoothed to produce the direct current supply voltage. This voltage is fed through a switching circuit and secondary smoothing circuit to produce a +24 VDC, +12 VDC, and -12 VDC supply.

  • Page 43: Control Circuit

    FilmScan 200 2.3 CONTROL CIRCUIT The scanner's control circuit is consists of two boards. 2.3.1 Control Circuit Outline The scanner CPU is an 16-bit, single chip M37720S1AFP, which operates at 14.74 MHz. To simplify the circuitry, the circuits for correcting the image data signals are collected into ASIC E02A14 and M6415.
