Abstract

PURPOSE:To simplify the constitution of a circuit by operating only a unit where a start signal arrives first and by inhibiting a unit where the start signal arrives later from operating until the former unit stops operating, by connecting common control signal terminals in common. CONSTITUTION:This circuit is provided with logic circuits 7 and 7' that outputs an operation permit signal operating units only when a start signal arrives at outputs of FF6 and 6' and start-signal input termials 5 and 5' of the unit, and units 12 and 13 that include priority determining circuits with output terminals 8 and 8' for the operation enabling signal operation units. Common control signal terminals 3 and 3' of those units 12 and 13 are connected by signal control line 11 and to signal terminals 3 and 3' of those units 12 and 13, on-off switching transistor TR2 and 2' are connected. Then, only a unit where the start signal arrives first is put into operation and the unit where the start signal arrives later is inhibited from operating until the former unit completes its operation, thereby simplifying the constitution of the circuit.
