Abstract
In an electronic image scanning device having an array of photosensitive elements, or photosites, arranged and supported for deriving electronic image information from an original, an arrangement for input of control information to the device includes a surface with a plurality of unique control images thereon, detectable by the photosites, is arranged for operator controlled movement. The scanning of the control images occurs during a non-image scanning period in the operation of the scanning device. The unique control images are recognized as control information. The operator controlled movement reflects operator selection of control information.
