Abstract

PURPOSE: To input plural kinds of signal with one key switch, by discriminating the length of the continuous operation time of the key switch.
CONSTITUTION: Key swith 11 is connected to control circuit 12 having the decision function such as a microcomputer. Circuit 12 checks the signal from switch 11, and checks whether the key switch is turned off or not while advancing the counter if switch 1 is turned on. If the continuous operation time (t) of switch 11 does not reach set time t0, it is decided that the first instruction is input, and operation 1 is executed. When switch 11 is turned on and continuous operation time (t) reaches time t0, it is decided that the second instruction is input, and another operation 2 is executed. Thus, it is possible to input plural kinds of signal by one switch.
