Claim:
A shutter mechanism of an automated-teller machine, for selectively opening and closing a cash receiving part in the automated-teller machine, comprising: a main body including a frame, a shutter slidably coupled to front side of the frame, a first protrusion protruding inward on an inner lateral surface of the shutter, and a fixing member protruding on a side surface of the frame; an opening/closing unit, for opening and closing the shutter in response to an external signal, including a first operation member having one end connected to the first protrusion and pivotably connected to the frame through a first rotational shaft, a first spring for causing the first operation member to be elastically supported by the fixing member, and a second protrusion formed on one surface of the first operation member to protrude toward the frame; a locking unit, for preventing the shutter from being opened by an external force without a separate signal, including a second operation member provided between the frame and the first operation member and pivotably connected to the frame through a second rotational shaft, a catching step formed to protrude from the second operation member and placed below the second protrusion, and a second spring for causing the second operation member to be elastically supported by the fixing member; and a driving unit for simultaneously operating the opening/closing unit and the locking unit.
