An exposure apparatus in which a photographic light-sensitive material is exposed to a light image of an original, includes: a light illuminating member for illuminating a light to the original; an optical member for projecting a light transmitted through or reflected on the illuminated original onto an exposure position as a line image of the original; a material conveyor for conveying the material at a constant speed while the line image of the original is projected onto the material; a moving member for moving the original at a definite speed while the line image of the original is projected onto the material; and a start position determining member for determining a start position of the original at which the moving member starts moving according to magnification of the projected image of the original or image density of the original. The moving member starts moving the original from the start position, thereby the definite speed of the original while the slit image of the original is projected onto the material, is varied.

Scanning exposure apparatus

A processing apparatus for a light-sensitive material includes a plurality of processing tanks for processing light-sensitive material; a kit including a container for accommodating a number of solid processing agents used for each processing tank; and solid processing agent replenishing device for replenishing the solid processing agents accommodated in the container into each processing tank. The apparatus further includes a memory for storing an amount of each solid processing agent used for processing a predetermined amount of light-sensitive material; a residual amount detector for detecting a residual amount of each solid processing agent and outputting a used up solid-processing-agent signal when the residual amount of each solid processing agent becomes zero; and a replacement requesting device for requesting the replacement of all solid processing agents in accordance with the used up solid-processing-agent signal of the solid processing agent.

Processing apparatus for light-sensitive material

A photographic printing apparatus includes a first and second magazines for storing a roll-shaped photographic light-sensitive material therein respectively, a first and second draw-out members each for drawing out the material from the first or second magazine at a first or second draw-out position, a first and second cutters for cutting the materials drawn out from the first and second draw-out members respectively, an accepting device for accepting and holding the materials drawn out from the first draw-out member at an exposure position, and a driving device for driving the accepting device from the first draw-out position to the second draw-out position. The driving device drives the accepting device which has held the material drawn out by the second draw-out member at the second draw-out position, from the second draw-out position to the first draw-out position so as to hold the material at the exposure position.

Photographic printing apparatus and a roll magazine holder therefor

An apparatus for processing a photographic paper, includes a distributor between an exposure station and a developing station so that plural sheets of photographic papers exposed at the exposure station can be conveyed in parallel in the developing station.

Photographic processing system

The invention provides an apparatus for printing an image of a negative film on a photographic print paper. The apparatus is equipped with a zoom lens for changing a printing magnification rate and the zoom lens incorporates an adjustable diaphragm for changing an aperture size. A standard F-number for each of possible magnification rates is predetermined in view of actual printing result, and a resultant F-number is stored in a memory for each of possible magnification rates. In the apparatus provided a sensor, disposed on the optical axis of the zoom lens, for detecting the illuminance of a projected surface on the photographic print paper and CPU for controlling the adjustable diaphragm in response to the detected illuminance to determine an optimum aperture size to obtain the predetermined F-number for each of possible magnification rates. The optimum aperture size is stored in the memory for each of possible magnification rates.
