PURPOSE:To preclude malfunction by providing a member which enters the moving operation range of a sensor means to interfere with the sensor means and inhibits the sensor means from moving by more than a specific quantity when a main device body is changed from a normal in-use attitude state to an attitude more than a specific angle attitude. CONSTITUTION:When a swing lever 34 rotates relatively according to the attitude conversion of the device and is received by a stopper pin 38, the projection part 37 on the side of the swing lever 34 is positioned within the swing operation range of the 2nd arm 31b of the swing lever 31. A swing lever 31, on the other hand, rotates relatively around a support shaft 33 in a sensor-on direction, but the projection part 37 on the side of the swing lever 34 is positioned within the swinging operation range of the 2nd arm 31b, so the swing lever 31 interferes with the projection part 37 of the 2nd arm 31b in the middle of the relative rotation and is inhibited from further rotating, so that a sensor-off state is maintained. Consequently, even if the device is changed from the normal in-use attitude state to an attitude more than the specific angle attitude although the main power switch of the device is on, no on signal is inputted from the sensor 30 to a device control circuit and the device is prevented from malfunctioning. |
