OVERVIEW
This section outlines the operations of the mechanism and control
units of the scanner.
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.
