Abstract
An original bearing a multicolor image is displaced in a transverse direction passed a scanning location and a strip extending transverse to this direction on the original is irradiated with a white light for a predetermined time period. During this time period a plurality of different color-component strips are optically derived each corresponding to a respective color component of the irradiated strip and each of these color component strips is applied to a respective solid-state transducer. A row of photodiodes in the transducer charges up respective capacitors therein during the scanning time period and the charges in these capacitors are read out seriatim and fed to respective scribers which reproduce the respective color component of the image on the original on the copy sheet. Dichroic mirrors tippable about axes parallel to the irradiated strip on the original are employed to pick off the separate color components.
