PURPOSE:To obtain many delay outputs from a delay circuit of small number of steps. CONSTITUTION:In cascade-connected flip flops 11 to 14, an input signal is output successively with a delay by a clock signal from a clock circuit 15. Four switching relays S1 to S4 are switched at each time of drawing out an output from the flip flop 14 in the final step to feedback this output to an input of the flip flop 11 in the first step. When a feedback signal is outputted by a time shift, a conducted relay switch is changed over, so that a control signal is given to remotely controlling relays R1 to R16 different from the preceding time. Since energization is necessary when an action condition is changed in the remotely controlling relays R1 to R16, energizing power of only one set amount is required supplied from a power transformer 21. |
