Abstract

PURPOSE:To obviate the emission of an alarm despite pushing of a reset switch right after the supply of a developing soln. to a storage tank by stopping the operation of a liquid detecting circuit for a prescribed time. CONSTITUTION:The output signal of a liquid detecting circuit 6 enters an alarm generating circuit 7 by passing through a timer 8. When there is no more developing soln. in a liquid detecting part 5 upon running out of the developing soln. 3 in a storge tank 1, an alarm signal is emitted from the circuit 7. When a reset switch is pushed after the developing soln. is supplied to the tank 1, the timer 8 is set, and the output signal of the circuit 6 is interrupted only for that delay time. Since this delay time has been set at above the time required for supplying the developing soln. from the tank 1 up to the part 5 by a pump 4, no input signal enters the circuit 7 despite pushing of the reset switch right after the supply of the developing soln. to the tank 1, hence no signal is emitted.
