Abstract:
A photosensitive-material processing-solution replenishing apparatus having a plurality of replenishing tanks for storing a plurality of types of replenishing solutions in which replenishing agents in concentrated form are diluted with dilution water, so as to replenish photosensitive-material processing tanks with the replenishing solutions in accordance with a quantity processed of a photosensitive material and collectively supply said plurality of replenishing tanks with the plurality of types of replenishing agents, comprising:an upper limit sensor provided in each of said replenishing tanks capable of detecting whether the levels of the surfaces of the replenishing solutions have exceeded a predetermined upper limit level;replenishing means for replenishing said processing tanks with the replenishing solutions in said replenishing tanks;a dilution water tank for storing the dilution water;dilution-water supplying means for supplying said replenishing tanks with the dilution water; andcontrolling means for controlling said dilution-water supplying means,wherein the controlling means revises the subsequent quantities of dilution water supplied on the basis of the quantities of replenishing solution replenished to the processing tanks between the time the replenishing agents and the fixed quantities of diluted water were supplied to the replenishing tanks until the levels of the solutions drop to the upper limit level.
