SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a medium storage cassette provided with a medium holding mechanism capable of reliably preventing a medium from dropping when being attached to or detached from an apparatus main body. [0007] According to an aspect of the present invention is to stacks and stores a plurality of sheet-like medium, can feed this stacked housed media the apparatus body side of the medium feeding means (pickup roller R 1, etc.) A medium storage cassette that can be mounted at a predetermined mounting position and that can be pulled out of the apparatus main body from the mounting position is characterized by including the following medium pressing mechanism. That is, the medium press mechanism according to the present invention is movably supported between a first position in contact with the upper surface of the stacked and stored medium and a second position separated from the upper surface. A first medium holding member (22);
A first urging member (24) for urging the first medium pressing member (22) toward the first position with a first urging force, and a first urging member (22) of the first medium pressing member (22). The first medium pressing member (2)
2) and a second medium pressing member (23) supported so as to be movable together with the first medium pressing member (22) when the first medium pressing member (22) is engaged. 22) moves the second medium pressing member (23) in the direction in which the second medium pressing member (23) moves to the second position while engaging with the second medium pressing member (23). A second urging member (25) for urging with a second urging force, and being supported so as to be movable by manual operation between a storage position taken after the mounting and a use position taken at the time of mounting and pulling out; And an engagement portion (26b) that engages with the second medium pressing member (23) when in the use position, and at the time of the engagement, against the second urging force, the second attachment member (26b). The second medium pressing member (23) is moved in the direction opposite to the direction of the force so as to move forward. The first medium pressing member (2
