<p>PURPOSE:To decrease the number of keys and make a computer small-sized, by constituting it so that the operation for driving and stopping the electric power supply can be controlled by utilizing a combined key operation of a double function indicating key and a key of FF except said key. CONSTITUTION:The combined key operation of a key F of FF13 except a double function key AC and the double function indicating key AC is detected by FF17. And the oscillator 7 stops oscillating by its detection signal, and since generation of clocks phi1, phi2 is stopped, the electric power supply stops driving. In this way, it is possible to decrease the number of keys and make the unit small-sized.</p> |
