A step portion 41 can be formed at a bottom surface 31 of the casing 30 so that the media can have a predetermined interval with the bottom surface 31 of the casing 30.

The slot shielding unit 100, as shown in FIGS. 2 and 3, includes: a shielding member 110 installed at an upper portion of the bottom surface 31 of the casing 30 where the discharging slot 40 is formed and having an area identical or larger than that of the discharging slot 40; an operating member 120 installed on the mounting portion 20 for opening the discharging slot 40 by moving the shielding member 110 when the casing 30 is mounted on the mounting portion 20; and a restoring member 130 for restoring the shielding member 110 to an initial position when the casing 30 is detached from the mounting portion 20.

The slot shielding unit 100 can be installed below the bottom surface 31 of the casing 30.

Both end portions 111 of the shielding member 110 are installed at the casing 30 by a guide portion 112 so as to be linearly movable. Especially, a movement preventing protrusion 113 for preventing the shielding member 110 from moving out of the casing 30 is formed at an upper surface of the shielding member 110.

The guide portion 112 fixed to a lateral surface 32 or a bottom surface 31 of the casing 30 is formed as a slot at the bottom surface 31 of the casing so that the shielding member 110 can be linearly movable. Also, the guide portion 112 can be formed as a slot at the lateral surface 32 of the casing 30.

The operating member 120 is protruded at the mounting portion 20 corresponding to the frontal surface 34 of the casing 30.

A receiving portion 121 for receiving the operating member 120 is formed at the frontal surface 34 of the casing 30, the operating member 120 is inserted into the receiving portion 121, and opens the discharging slot 40 by moving both end portions 111 of the shielding member 110. Especially, the receiving portion 121 can be formed at both end portions of the frontal surface 34 of the casing 30.

The restoring member 130 for restoring the shielding member 110 to an initial position is formed by a coil spring or a plate spring in the first embodiment of the present invention. The restoring member 130 is fixed on the bottom surface 31 opposite to the frontal surface 34 on the basis of the shielding member 110 by a fixation member 131 formed at the bottom surface 31 of the casing 30. Especially, the guide portion 112 can be fixed to an upper surface of the fixation member 131.

In the media cassette according to the first embodiment of the present invention, as shown in FIG. 2, the media stacked in the casing 30 are not left out by their weight before mounted on the mounting portion 20 of the media dispenser 10 because the discharging slot 40 is shielded by the shielding member 110.

Also, when the media cassette is mounted on the mounting portion 20, the operating member 120 installed at the mounting portion 20 is inserted into the receiving portion 121 and pushes said both end portions 111 of the shielding member 110, thereby opening the discharging slot 40 as shown in FIG. 3.

FIG. 4 is a lateral view of a media cassette according to the second preferred embodiment of the present invention, FIG. 5 is a sectional view showing an aspect before the media cassette of FIG. 4 is mounted on a mounting portion, FIG. 6 is a sectional view showing an aspect after the media cassette of FIG. 4 is mounted on the mounting portion, and FIG. 7 is a construction view showing a construction of a slot shielding unit of the media cassette of FIG. 4.

A construction of the media cassette according to the second embodiment of the present invention is similar to that of the first embodiment except a construction of the slot shielding portion, thereby omitting its explanation.

The shielding member 210 of the slot shielding unit 200, as shown in FIGS. 4 to 7, is constructed as a pair, and an end portion thereof is fixed to a rotary shaft 211 rotatably installed at the bottom surface 31 of the casing 30 near both ends of the discharging slot 40. Also, an interacting member 240 for opening the discharging slot 40 by interacting with the operating member 220 and rotating the rotary shaft 211 is connected to the rotary shaft 211. Also, the restoring member 230 such as a torsion spring is constructed inserted to the rotary shaft 211.

The interacting member 240 is protruded out of the lateral surface 32 of the casing 30 through a through hole 241 formed at the lateral surface 32 of the casing 30.

Also, the operating member 220 is constructed as a pair of magnets protruded towards each side of the frontal surface 34 of the casing 30 when the casing 30 is engaged to the mounting portion 20 corresponding to the frontal surface 34 of the casing 30.

The shielding member 210 includes an end portion 210a having a width identical or larger than that of the discharging slot 40, and a middle portion 210b concavely cut between the end portion 210a and the rotary shaft 211.

A movement preventing protrusion 213 for preventing the media from moving out of the frontal surface is formed at the upper surface of the shielding member 210.

In the media cassette according to the second embodiment of the present invention, as shown in FIG. 5, the media stacked in the casing 30 are not left out by their weight before mounted to the mounting portion 20 of the media dispenser 10 because the discharging slot 40 is shielded by the shielding member 210.

Also, as shown in FIG. 6, when the media cassette is mounted on the mounting portion 20, the interacting member 240 is engaged to the magnet, that is, the operating member 220 installed at the mounting portion 20, by magnetic force, thereby rotating the rotary shaft 211. As the rotary shaft 211 is rotated, the shielding member 210 is rotated, thereby opening the discharging slot 40.

Especially, in case that the media cassette according to the present invention is used in the ATM, media stacked in the media cassette is dispensed through the discharging slot by a transport unit with its operation.

The media cassette according to the present invention is provided with the slot shielding unit which is opened only when mounted on the media dispenser, so that the media stacked therein are not left out in a state that the media cassette is detached from the media dispenser.
