In an image forming apparatus provided with an exposing section and a conveyor for conveying a plurality of light sensitive materials relative to the exposing section, the plurality of light sensitive materials are arranged in parallel in the conveying direction so that the exposing section is divided into plural exposing blocks corresponding to the plurality of light sensitive materials. There are provided a memory to memorize plural correction amounts each set based on a characteristic of one of the plurality of light sensitive materials, wherein the plural correction amounts are correlated with the plural exposing blocks in accordance with the corresponding light sensitive material; and a correcting section to correct the amount of light for each exposing block on the basis of the corresponding correction amount.

Image forming apparatus

An automatic developer for developing a light-sensitive material such as a photographic material. The developer includes: a processor tank for accommodating a processing solution so that the processing solution processes the light-sensitive material; a throughput detector for detecting a throughput of the processor on the light-sensitive material, and for generating detection signals when the throughput becomes a predetermined value; a processing agent supplier for supplying a solid processing agent to the processor tank; a water supplier for supplying water to the processor tank; a calculator for calculating an amount of evaporation water of the processing solution; a timer for generating timer signals when a predetermined time period is passed from a reference time; a controller for controlling the processing agent supplier to supply the solid processing agent to the processor tank according to the detection signals, for controlling the water supplier to supply the water to the processor tank according to the detection signals in which an amount of the water for each time is not more than a predetermined supply amount, and for controlling the water supplier to supply the water corresponding the amount of evaporation water in accordance with the timer signals.

Automatic processing apparatus for silver halide photographic

An automatic developing apparatus for developing a photosensitive material includes a processing section, a throughput detector, a processing agent supplier, a water supplier, a calculator, a timer and a controller. The processing section accommodates a processing solution for processing the photosensitive material. The processing solution comprises a solid processing agent dissolved in water. The throughput detector detects a throughput of the photosensitive material through the processing section, and generates detection signals when the throughput becomes a predetermined value. The processing agent supplier supplies the solid processing agent to the processing section, and the water supplier supplies water to the processing section. The calculator calculates an amount of evaporation water evaporated from the processing solution, and the timer generates timer signals when a predetermined time period elapses. The controller controls the processing agent supplier and the water supplier to respectively supply to the processing section the solid processing agent and an amount of water not greater than a first predetermined supply amount responsive to the detection signals. The first predetermined supply amount is calculated in accordance with an allowable range of variations of concentration of the processing solution in the processing section. The controller also controls the water supplier to supply to the processing section an amount of water corresponding to the amount of evaporation water responsive to the timer signals.

Automatic developing apparatus, using solid processing agent dissolved

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.
