Abstract
A float sensor system for a replenishing tank 70 including an injection nozzle 80 attachable to a liquid feeding nozzle 60 of a replenishing device 70 for replenishing processing liquid to a development processing tank unit. This system includes a float 82 provided to the injection nozzle 80 of a replenishing tank 71-74 and movable between a first position and a second position, and a float detecting sensor 64 mounted to the liquid feeding nozzle 60. When an amount of liquid in the replenishing tank attached to the liquid feeding nozzle 60 exceeds a predetermined value, the float 82 is moved to the first position. When the liquid amount is lower than the predetermined level, the float 82 is moved to the second position. Also, the float detecting sensor 64 outputs a float detection signal when the float 82 is located at this second position.
