Patent ID: 7828563

Claim:
An electronic device, comprising: an electronic device main body provided with an external device connection terminal and a plurality of manipulation keys; an external device manipulation unit to surround the connection terminal, the external device manipulation unit being movable in at least two positions; and a main control unit to control manipulation signals input from the manipulation keys and the external device manipulation unit wherein the external device manipulation unit comprises: a manipulation unit being manipulated in a state that the manipulation unit surrounds the connection terminal; a switch being operated by the manipulation unit; and a circuit board on which the connection terminal and the switch are disposed so that the connection terminal and the switch can exchange signals, and the circuit board transferring the signals to the main control unit, wherein the manipulation unit is rotatable between a standby position and a manipulation position, wherein the manipulation unit comprises: a rotary member to rotate from an initial position along an outer periphery of a connection terminal holder to support the connection terminal; a projection, formed to project from the rotary member, to operate the switch by a movement of the rotary member; and an elastic unit to return the rotary member to the initial position.
