<p>PURPOSE:To prevent the mis-operation of a power source switch from being generated, and to improve operability, by impressing a power source voltage by an instruction from a power source switch when a power source is turned ON, and stopping the impression of the power source voltage by the instruction from an input means, when the power source is turned OFF, in a picture information memory retrieving device. CONSTITUTION:The titled device is constituted of the power source switch which issues the instruction to impress the power source voltage, the input means which inputs the instruction to stop the impression of the power source voltage being impressed o the device, and a control means which stops the impression of the power source voltage by the instruction from the input means. In a power source part 31, when a power source switch SW2 is turned ON in a state that a main switch SW1 is already applied, a relay circuit 33 goes to an ON state by a power source control circuit 36, and a prescribed power source voltage is impressed on a picture information processing part 3 from a power source circuit 34, and the instruction from the power switch SW2 is nullified. The power source part 31, when the instruction to stop the power source voltage from a keyboard 23, and an OFF signal from a CPU12 are supplied, stops the power source voltage from the power source circuit 34 by generating the OFF state of the relay circuit 33 by the power source control circuit 36. In this way, the power source of the picture information processing part 3 is turned OFF.</p> |
