PCT No. PCT/AU86/00363 Sec. 371 Date Jul. 27, 1987 Sec. 102(e) Date Jul. 27, 1987 PCT Filed Nov. 26, 1986 PCT Pub. No. WO87/03388 PCT Pub. Date Jun. 4, 1987.A photo-electric imaging device having an array of rows (7) of minute electrodes (8) and an array of columns (1) of electrodes (4) overlying the rows and separated by semiconductor layer (6). Imaging plates (11) are positioned above each pair of respective electrodes (4, 8) and separated from them by an interface (10). A photoconductive layer (12) may be placed over the imaging plate (11). A writing surface (12) over the imaging plates (11) is produced which comprises a multiplicity of spaced discrete areas each independently addressable by selecting a row and a column.
