摘要

The invention relates to a device for graphical representation on a recording medium. The device comprises a chassis 1 on which is mounted at least one inscribing member 2 which can move with respect to the medium. The medium S is a photographic plate and the inscribing member 2 is an electro-optical transducer placed and held in contact with the medium during the movement of the inscribing member with respect to it. The transducer is capable of producing a light beam, the diameter of whose exit pupil in the region of the medium S is less than 50 mu m.
