Abstract

PURPOSE:To make effective the switch finally depressed only, by inhibiting the input of other switches, when closing one switch. CONSTITUTION:When the switch Sd in a circuit 3-2 is closed, the input of an inverter 4 and an AND gate 5 is low. Since the output of the inverter 4 is high, the output of an NAND gate 6 is energized low. At this time point, since the output of an NOR gate 7 is energized high, a monostable multivibrator 8 is triggered and a positive pulse is fed to a clock input T of a flip-flop 9 to set the flip-flop 9 of the circuit 3-2. In this case, since a low input is present at the data input D, the output of the flip-flop 9 is low. By depressing the switch Sd, the input inhibiting signal is fed to the lower rank NAND gate 6 and NOR gate 7 from the upper rank.
