Kind Code:
A1
Abstract:
In order to increase sharing of attachment/detachment mechanisms between device main bodies and power supply devices and to prevent erroneous attachment of an unsuitable power supply device, among a plurality of power supply devices having different output voltages, to the device main body, this electric device comprises a common device main body 10c having selectively and detachably attached thereto either a variable-voltage power supply device or a high-voltage power supply device. The device main body 10c has: a protruding section 15 to which abuts a power supply-side main erroneous attachment prevention section 25 provided in the variable-voltage power supply device and the high-voltage power supply device; a device-side main erroneous attachment prevention section 33a that abuts the power supply-side main erroneous attachment prevention section 25 provided in a low-voltage power supply device and prevents the low-voltage power supply device from abutting an attachment positioning section; and a device-side attachment permitting section 52 that can be combined in a power supply-side auxiliary erroneous attachment prevention section 51 provided in the high-voltage power supply device.
