ABSTRACT:
A horizontal portion of an original document is scanned by means of N linear photosensor arrays arranged in a row. Each array has M photosensor elements. M strobe pulses are sequentially applied to the M photosensor elements of all of the arrays in parallel, the photosensor elements producing output signals in response to the respective strobe pulses. The output signals of the N photosensor arrays are applied in parallel to N printing electrode arrays for simultaneous printing, thus enabling high speed copying. The photosensor arrays are adapted to be strobed in sequence for facsimile transmission. A storage means is adapted to receive M.times.N facsimile input signals, divide the signals into N groups of M signals each and simultaneously feed the signal groups to the respective electrode arrays, the M individual signals of each group being fed to the respective electrode array serially. Alternatively, the groups of signals may be fed to the respective electrode groups sequentially rather than simultaneously.
