PURPOSE: An electronic device is provided to ensure a door to be locked/separated to/from a wall of the device by comprising a member which can be coupled and separated into/from both sides of openings defined in the wall as coupled to a door. CONSTITUTION: A door(52) is locked and separated to/from a bottom housing(20) by a spring(90) to open and close openings(30,42). A battery(16) for access is inserted into the bottom housing(20) through an opening defined in the side wall of the bottom housing(20). Then, the door(52) is coupled between both sides(32) of the opening(30). By pulling a knob(80) of the door assembly downward, a compressing part(94) of a spring(90) is pressed by a knob holder(84) so that both ends(98) of the spring(90) are inserted into the door(52). Then, by pushing the door(52) between the both sides(32) of the opening, and releasing the knob(80), the both ends(98) of the spring(90) are inserted into grooves(34) defined in the both sides(32) of the opening(30), thereby locking the door(52) to the bottom housing(20).
