Claim:
An apparatus, comprising a casing configured to receive dispensed media; a door configured to cover an opening portion of the casing, and to move between a first position where the casing is open and the dispensed media is accessible to the outside and a second position where the casing is closed, wherein the door comprises a pair of catching portions respectively formed on both sides of the door corresponding to both sides of the opening portion of the casing; and a locking mechanism configured to selectively engage each of the pair of catching portions when the door is in the second position so as to secure the door in the second position when engaged, wherein a first end of the locking mechanism is operatively coupled to a portion of the casing, and a second end of the locking mechanism is configured to operate about the first end and to selectively engage with each of the pair of catching portions, wherein the locking mechanism comprises: a rotary shaft installed on the casing in a transverse direction of the media holder; a pair of rotatable catching members coupled to the rotary shaft and configured to be respectively engaged by the pair of catching portions when the door is closed; and a catching member driving portion installed on a side portion of the media holder and configured to rotate the pair of catching members so as to disengage the pair of catching members when the door is opened, wherein the catching member driving portion is installed on only one side surface of the media holder, and when one of the pair of catching members is rotated by the catching member driving portion, the other catching member is rotated in response to a rotation of the rotary shaft, and wherein the catching member driving portion comprises a linear driving device, wherein an end portion of the catching member driving portion is coupled to one of the pair of catching members at a position apart from where the catching member is coupled to the rotary shaft, and wherein the catching member driving portion is configured to drive a shaft thereof in a direction substantially perpendicular to a moving direction of the door, and wherein the pair of catching members are aligned with the pair of catching portions.
