Abstract
The insertion of exposed film into a developing tank 1 is detected by a detector 12, by which a pump motor 8 is operated by a control circuit 20, to agitating continuously the developing solution filled in the tank, and simultaneously a pulse counter 16 stars counting pulses generated from a pulse generator 14. The continuous agitation of the developing solution is suspended when the film is discharged from the tank, which is measured by counting up to the predetermined number which corresponds to the time required for the film treatment in the tank. When the pulse counter 16 counts up to the predetermined number, the intermittent agitation of the developing solution is started by the control circuit 20, to keep the developing solution uniform.
