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

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.
