a movable shutter placed at the cassette body to open and close the entrance according to connection and separation of the cassette body with respect to the cassette receiving portion; a movable first medium support portion placed in the cassette body to push the paper medium toward the entrance; a movable second medium support portion movably placed at the entrance so that the paper medium is disposed between the first medium support portion and the second medium support portion; a movable connection portion connected to each of opposite ends of the second medium support portion and placed at opposite lateral sides of the cassette body; and a rotatable medium return gear portion placed at each of the opposite lateral sides of the cassette body so as to be connected to a connection portion gear connected to the connection portion and to a shutter gear placed at the shutter, the medium return gear portion configured to forcibly move the connection portion in a first direction away from the entrance by a moving force of the shutter when the entrance is closed. ### Claim 2 (depends on 1) The cassette of claim 1, wherein the opposite ends of the second medium support portion comprises connection holes or connection grooves in which connection projections placed at the movable connection portion are inserted, the connection holes or the connection grooves extend in a movement direction of the second medium support portion to be longer than a movement distance of the second medium support portion, and the second medium support portion and the cassette body comprise a return spring to provide an elastic force in a second direction toward an initial position of the second medium support portion. ### Claim 3 (depends on 2) The cassette of claim 2, further comprising a locking portion disposed at each of the opposite lateral sides of the cassette body, respectively, to restrict movement of the second medium support portion until the first medium support portion is operated when the connection portion is moved in the second direction. ### Claim 4 (depends on 3) The cassette of claim 3, wherein the opposite ends of the second medium support portion comprise a locking hole or locking recess, and the locking portion comprises: a movably locking projection at the cassette body to be inserted in the locking hole or locking recess when the second medium support portion is moved in the first direction and separated from the locking hole or locking recess when the second medium support portion is moved in the second direction; and an elastic member disposed between the locking projection and the cassette body to elastically support the locking projection. ### Claim 5 (depends on 2) The cassette of claim 2, wherein the shutter gear is extended by a predetermined length at each of the opposite lateral sides of the shutter to move the connection portion by a predetermined distance in the first direction at the beginning of closing the entrance or to move the connection portion by a predetermined distance in the second direction right before the entrance is fully opened. ### Claim 6 (depends on 5) The cassette of claim 5, wherein the shutter comprises a first stopper disposed at each opposite sides to the opposite lateral sides of the shutter and extended in a movement direction of the shutter, and the medium return gear portion comprises a second stopper disposed at one side of the medium return gear portion to be brought into contact with the first stopper in a sliding manner so as to restrict rotation of the medium return gear portion when the shutter gear and the medium return gear portion are not connected. ### Claim 7 (depends on 1) The cassette of claim 1, wherein the opposite lateral sides of the cassette body each comprise a pressed portion pressed by a predetermined depth by interference with an interference portion formed at the cassette receiving portion when the cassette is connected, the pressed portion comprises a pressed portion gear disposed at one side of the pressed portion to restrict rotation of the medium return gear portion through connection with the medium return gear portion, and connection between the medium return gear portion and the pressed portion gear is released when the pressed portion is pressed by the predetermined depth. ### Claim 8 (depends on 7) The cassette of claim 7, wherein the pressed portion is interfered with the interference portion before the medium return gear portion and the shutter gear are connected when the cassette is connected, and interference between the pressed portion and the interference portion is released after the medium return gear portion and the shutter gear are connected when the cassette is separated. ### Claim 9 (depends on 1) The cassette of claim 1, wherein the second medium support portion comprises: a movable support portion body disposed in the cassette body, opposite ends of which are extended along the opposite lateral sides of the cassette body; a plurality of support projections protruded from the support portion body toward the entrance and brought into contact with the paper medium when the connection portion is returned in the first direction; and a removable rubber pad connected by enclosing an outer circumference of the support projections to increase a contact force between the support projections and the paper medium. ### Claim 10 (depends on 9) The cassette of claim 9, wherein the rubber pad comprises: an upper fitting portion of a ring shape to be fit with an upper fixing recess formed at an upper portion of each of the support projection; a lower fitting portion of a ring shape to be fit with a lower fixing recess of each of the support projections; and a contact portion connected to the upper fitting portion and the lower fitting portion and disposed at a contact surface of the support projections contacting the paper medium.
