Abstract

PURPOSE:To prevent more than one input and output equipments from being used simultaneously in a system by setting one input and output equipment in an operation state and by inhibiting other input and output equipments from operating by transmitting a declaration signal from the equipment. CONSTITUTION:When there is no declaration signal on the declaration-signal line l5 of a priority comparing circuit PC, the switch of a setter S is operated to send its set output from a logical circuit 13b to the control part 12 of an input and output circuit C1, and the transmission state of this declaration signal is maintained while the input and output device C1 is in operation. If a declaration signal is alrady sent through the line ls from one of input and output equipments C2... when the setter S is set, the declaration signal is received by a logical circuit 13a, which turns off the circuit 13b, so no set output is sent from the circuit 13b even if the setter S is set, thereby inhibiting the input and output equipment C1 from operating.
