A process and device for the output of electronic image signals on light-sensitive recording material is disclosed. A two-dimensional, transmissive display element, in particular a liquid crystal display (LCD), is controlled by the image signals and the beam of at least one light source passes therethrough in the direction of the light-sensitive recording material. During video output, the display element is arranged so near to the recording material that a sharp picture is produced on the recording material without having to position additional focusing, optical means between the display element and the recording material.

Process and device for the output of electronic image signals, and a photographic copier

A device for winding strips of photographic film inside a housing. A film-guide slot opens into the housing's approximately cylindrical interior. A film reel rotates freely in the housing interior without a positive drive and demarcates, in conjunction with the inner surface of the housing, a more or less annular film-guide channel. The film-guide slot opens more or less tangentially into the interior channel.

Device for winding strips of photographic film

A microfilm reading and reverse enlarging apparatus with a copying beam for a gap illumination comprises a copy carrier movable with a constant speed, drive device for moving the copy carrier, a film platform for a film and adjustable relative to an illuminating beam, transporting device for reciprocating the film platform synchronously with the movement of the copy carrier, control device for controlling the transporting device, a potentiometer adjustable by the transporting device synchronously with the movement of the platform so as to produce respective values in response to the movement of the platform during a copying process of successive microimages, and storing and comparing device arranged to store preselected values and to receive the values of the potentiometer to compare them with the preselected values, the storing and comparing device being connected with the control device so that the transporting device and the drive device for the copy carrier during reaching by the values of the potentiometer the preselected values are turned on and/or turned off.

Microfilm reading and reverse enlarging apparatus

A device for controlling the width of a slot of a diaphragm of a microfilm-reading-and-copying apparatus in which an enlarged microimage is projected by two inclined mirrors mounted on a movable carriage and via the slot of the diaphragm on a copying cylinder. The diaphragm is formed by two flaps of which one is stationary and another one is movable between a closed position to close the slot and a plurality of open positions to adjust the width of the slot. The drive of the movable flap is provided with a rotatable cam which is coupled to the movable carriage.
