An electronic device (30) of the this invention includes an external device connecting connector (33) to be connected to a power supplying connector (40) of an external device (41) having a power supplying function, an electronic circuit (31) which performs predetermined operation upon reception of power supplied from the external device through the external device connecting connector, and an electromagnet (32) which is provided to the external device connecting connector and electrically connected between the external device connecting connector and the electronic circuit. The electromagnet generates a magnetic force when a power supply current supplied from the external device flows through it, and attracts a predetermined portion formed of a magnetic body of the power supplying connector, to maintain a fitting state between the external device connecting connector and the power supplying connector. Thus, the fitting state becomes reliable. When supply of the power supply current from the external device is stopped, the fitting state is canceled. Thus, the power supplying connector can be pulled out from the external device connecting connector readily, so that any damages can be prevented. |
