OVERVIEW
Operation of the mechanism unit
The mechanism unit consists of two optical units (front and back sides), a hopper and ADF, upper and lower transport units, a motor drive system, and a stacker. Each optical unit consists of a CCD image sensor, a lens, and mirrors. The hopper and ADF feeds stacked documents and the upper and lower transport units transport the documents. The motor drive system drives these units. The stacker stores documents.
When the power is turned on, the lamps are lit and the scanner waits until the light intensities of the lamps become stable. Once the light intensities have become stable, the scanner is ready for a command from the host machine.
A document is picked from the hopper and then ADF feeds a document one by one. The document width is checked and document top is detected.
The documents are counted, fed, and stacked on the stacker.
The lamps illuminate the document, and a lens focuses the images on CCD for photoelectric conversion processing.
