<p>PURPOSE:To reduce the operation load by providing a driving means which moves a plane display part to arrange it to a prescribed position and a return control means which controls the driving means based on the power-on/off indication input to return the plane display part to a prescribed storage position. CONSTITUTION:A driving circuit 4 consists of a driver and a stepping motor, and the stepping motor is so driven that a plane display part 2 is arranged from the home position to a prescribed operation position. A CPU 1 functions as the return control means; and when a power switch 7 is switched from the turning-on state to the turning-off state, an inter-rupe command IRQ as the power-on/off indication is outputted to the interrupt input of the CPU 1, and the stepping motor as the driving means is controlled to return the plane display part 2 to the prescribed storage position (home position), and thereafter, a power control circuit 5 turns off a power source 6. Thus, the display device is automatically returned to the prescribed storage position, then, the user's load is reduced.</p> |
