ABSTRACT:
A linear array of optical sensing elements is moved transversely to the relative motion of an optical image such that each element can sense the optical density of pixels over which is passes, and such that all pixels in each of successive rasters across the image are sensed by at least one optical sensing element.
The linear array of optical sensing elements may be combined with a linear array of printing elements in a single moving head to share components and thus to reduce cost of a facsimile transceiver.
