Реферат: ABSTRACT: Device for the optical scanning of a document. The device comprises a transducer (3) with photoelectric elements (31) and a coupling member (5) which comprises an entrance face (9) which is to be aimed at the document and an exit face ( 11 ) which is optically coupled to the transducer. The coupling member (5) comprises a number of light conductors (7) having first ends (13) which are arranged in at least one straight line in the entrance face (9) and second ends (21) which are situated in arbitrary positions in the exit face (11). The relation between the positions of the first ends (13) in the entrance face (9) and the positions of the second ends (21) in the exit face (11) is stored in a memory (29). The photosensitive surface of the transducer (3) may have an arbitrary length/width ratio and the light conductors (7) may extend rather arbitrarily through the coupling member (5) so that the cost of the device may be comparatively low.
