Abstract
When CPU 2 is in the standby state, switch S4 is turned OFF such that switch S1 is not connected to condenser C1 and the signals from switch S1 are pulled up by means of resistor R2. When CPU 2 becomes activated through the detection of a change in the state of switch S1, switches S3, S4 and S5 are turned ON to connect condenser C1 and resistor R1 to switch S1 and to connect resistor R3 to switch S2. Through this construction, the chattering in switches S1 and S2 may be eliminated, and CPU 2, which is in a standby state, may be activated based on signals from switch S1.
