Automatic processing apparatus

An automatic processing apparatus for processing photosensitive material by sequentially conveying and dipping said photosensitive material in a plurality of processing solution tanks storing processing solution, said automatic processing apparatus comprising:

• a pair of rollers provided in the vicinity of an intermediate portion between two adjacent tanks of said plurality of processing solution tanks and above an upstream processing solution tank of said two adjacent tanks to convey said photosensitive material to a downstream processing solution tank of said two adjacent tanks, and squeeze off processing solution adhering to a photosensitive material surface;
• replenishing solution supply means for supplying replenishing solution into said upstream processing solution tank of said plurality of processing solution tanks when said photosensitive material is being processed;
• diluting water supply means provided in the vicinity of said pair of rollers for supplying diluting water into said processing solution tank through said pair of rollers for diluting said replenishing solution to a predetermined concentration, said diluting water supply means including a spray pipe for ejecting said diluting water toward said pair of rollers, and said pair of rollers being washed by said diluting water;
• and
• a trough into which one roller of said pair of rollers is partially dipped, for storing said diluting water by receiving said diluting water ejected from said spray pipe through said pair of rollers, and excess of said diluting water overflowing from said trough into said upstream processing solution tank.

An automatic processing apparatus for processing photosensitive material by sequentially dipping said photosensitive material into a plurality of processing solution tanks storing processing solution while conveying said photosensitive material, said automatic processing apparatus comprising:

• a pair of rollers provided between two adjacent tanks of said plurality of processing solution tanks so as to convey said photosensitive material from an upstream processing solution tank of said two adjacent tanks to a downstream processing solution tank of said two adjacent tanks;
• replenishing solution supply means for supplying replenishing solution into said plurality of processing solution tanks, respectively;
• diluting water supply means for supplying said upstream processing solution tank with diluting water for diluting said replenishing solution to a predetermined concentration in synchronization with supply of said replenishing solution by said replenishing solution supply means;
• a diluting water trough provided below said pair of rollers to receive diluting water from said diluting water supply means, and store said diluting water such that a lower roller of said pair of rollers is partially immersed in said trough;
• and
• a notch portion provided in said trough so as to cause said stored diluting water to flow in an amount of overflow from said notch portion into said processing solution tank on the upstream side.
