ABSTRACT:
Material such as a document or picture of which an image is to be reproduced or transmitted, as in a facsimile device, is driven by pinch rollers past a light source in a controlled synchronized manner by means of a stepping motor. As the pinch rollers are driven, successive scan line images of the document are channelled through an elongated slit in a light directing channel and through a lens and a rotatably driven color wheel onto a light sensitive device such a linear array formed by a charge-coupled device (CCD). The color wheel has light filters for the primary colors and is synchronized with the scanning. The images received by the CCD are converted thereby to electrical form and appropriately processed for transmission or local utilization. A mechanism is provided to enable the disengagement of the pinch rollers from the material being scanned to avoid damage to such material should it become jammed in the rollers.
