Photosensitive material processor

A photosensitive material processor for processing a photosensitive material by consecutively transporting the photosensitive material to a plurality of processing tanks in which processing solutions are accommodated therein, respectively, comprising:

• a solution supplying section in which a cartridge having a plurality of partitioned chambers with mutually different stock solutions accommodated therein is loaded;
• a plurality of stock tanks for respectively storing the stock solutions supplied from said solution supplying section so as to replenish the processing solutions in said processing tanks;
• level detecting means mounted on said plurality of stock tanks, respectively, and adapted to detect the solution levels of the stock solutions in said stock tanks;
• and
• control means for forcedly discharging remaining ones of the stock solutions when said level detecting means detects that at least one of the solution levels has reached a predetermine value or less.

A photosensitive material processor having a processing tank for processing a photosensitive material, comprising:

• a mixing tank for preparing a processing solution by mixing a stock solution and a dilution liquid;
• a stock solution supplying pump for supplying the stock solution to said mixing tank;
• a dilution liquid supplying pump for supplying the dilution liquid to said mixing tank;
• a pipe for connecting said mixing tank and said processing tank so that the processing solution prepared in said mixing tank is supplied to said processing tank;
• and
• control means for controlling said stock solution supplying pump and said dilution liquid supplying pump with a predetermined ratio of periods of discharge of the liquids such that the periods of discharge of the liquids partially overlap with each other, and such that timings at which the discharge of the liquids is stopped become simultaneous or substantially simultaneous.
