A method and apparatus for correcting deviation from a constant scanning speed of a galvanometer driven by a linear drive signal, characterized in that the linear drive signal for driving the galvanometer is converted into a non-linear drive signal in accordance with predetermined correction data to thereby reduce the deviation to zero.

Apparatus for correcting scanning rate deviation of a galvanometer and

A form data compressing method in which form data are stored in memory for every raster, the raster data pattern of each raster is divided into a plurality of units each having a plurality of bits, the unit data patterns of these units are subjected to comparison to perform the compression in unit order direction, and according to the compression data obtained by the compression in unit order direction the compression in raster order direction is carried out.

Apparatus for and method of compressing form data

A number of format films carrying fixed information to be recorded together with computer output information given by a magnetic tape are vertically stacked in a cassette. The cassette is supported on a vertically movable cassette support. At a predetermined level which is of the same level as a projection station where the format film is brought and the image of the film is projected there is provided a format film gripping device. The format film gripping device has a fixed arm and a swingable arm which are opened at the cassette and closed to grip one of the format films in the cassette when the gripping device is driven to take out one of the format films from the cassette and brings the taken out format film to the projection station. The vertically movable cassette support is moved up and down stepwisely to selectively bring one of the format films to be projected to the predetermined level where the format film is taken out of the cassette and brought to the projection station.

Format film selecting device

A camera portion and a processor portion are combined so that the film exposed in the camera portion is processed in the processor portion. The camera portion is provided with a roll film take-up magazine and a cutter for cutting a roll film into sheet film. When roll processing is desired, the exposed roll film is taken up in the roll film take-up magazine and the magazine is put into the processing portion. When sheet processing is desired, the exposed roll film is cut into sheet film in the camera portion and fed into the processor portion. The processor portion is provided with a first film passage for guiding the sheet film into the processor and a second film passage for guiding the roll film into the processor. The processor portion has a roll film magazine holding device for holding the roll film take-up magazine so that the roll film taken out thereof is guided into the processor through the second film passage.
