PURPOSE:To constitute a sequence control circuit which can be assembled, repaired and modified easily, by arraying in parallel plural FF circuits corresponding to one operation of the sequence control, and controlling them in due order. CONSTITUTION:The diode matrix is constituted of the respective output lines X1- X7 of the FF circuits (b)-(h) and the Y1-Y3 lines crossing said lines. Also, the pulse generators 4X, 4a-4c or the timers 9d-9h are connected to the set terminals of the respective FF circuits, respectively. At this time, when the switches 2, 3a-3c are operated in order, the FF circuits are turned on in order accordingly, or turned on, being delayed by a delay time by the timer. And, when the sequence control ends at last, a reset signal is provided to each FF circuit, and it is returned to its initial state. In this way, it is possible to constitute a sequence control circuit which can be increased and modified freely and also can be assembled and repaired easily. |
