Abstract
Material which may be a document or picture of which an image is to be produced or transmission, as in a facsimile device, is driven by pinch rollers means of past a light source in a controlled, synchronized manner by a stepping motor. As the rollers are driven, successive scan line images of the document are channeled through an elongated slit and a light-directing channel through a lens onto a light-sensitive device, such as a linear array formed by a charge-coupled device (CCD). The images received by the CCD are converted thereby to electrical form and appropriately processed for transmission or other utilization.
