According to this, as the eject bar 54 rises, the raised portion 542 formed on the eject bar 54 raises the disc 9 disposed along the bottom surface 53A. Extraction can be performed easily. At this time, the gap between the lid member 6 and the raising portion 542 becomes larger according to the rotation amount of the lid member 6, so that the disk storage portion 53 is adjusted by adjusting the size of the guide hole 621 of the lid member 6. The disk 9 can be taken out from the disk and the disk 9 can be stored in the disk storage portion 53 more easily. Therefore, compared to the case where the holder for storing the disk 9 is provided in the lid member 6, the disk 9 can be easily taken out and stored, and the configuration of the disk storage portion 53 can be simplified.

(2) When the lid member 6 is in the closed state and the eject bar 54 is disposed along the disc storage portion 53, the raising portion 542 formed on the eject bar 54 is located at the center of the disc storage portion 53. It is located on the opposite side to the direction from the turntable 532 to the support portion 537, that is, between the turntable 532 and the bar mounting portion 539.
According to this, when the lid member 6 is in the open state, the raised portion 542 has the arcuate portion 923 side that is the proximal end side in the insertion direction of the disk 9 and the semicircular portion 922 that is the distal end side in the insertion direction. It can be separated from the bottom surface 53A from the side. Accordingly, the proximal end side in the insertion direction of the disc 9 with respect to the disc storage portion 53 can be easily grasped, so that the disc 9 can be taken out from the disc storage portion 53 more easily.
Further, as described above, since the raising portion 542 is located between the turntable 532 and the bar mounting portion 539 on the bottom surface 53A, when the disc 9 is stored in the disc storage portion 53, the disc 9 is inserted into the turntable. Damage to the 532 and the pickup 533 can be prevented.

(3) The eject bar 54 includes a pair of arm portions 541, and the arm portions 541 are arranged so as to sandwich the disc 9 stored in the disc storage portion 53. And the raising part 542 is formed in plate shape so that each arm part 541 may be connected.
According to this, the raising portion 542 can surely support the disc 9, and the disc 9 supported by the raising portion 542 can be prevented from tilting with the insertion direction of the disc 9 as an axis. . Therefore, the raising portion 542 can stably support the disk 9 and the disk 9 can be taken out more easily.
Further, when the disk 9 is stored in the disk storage portion 53, these arm portions 541 guide the disk 9. Thereby, the disk 9 can be stored in the disk storage unit 9 more easily.

(4) Each arm portion 541 of the eject bar 54 is formed with a projection 5412 that is inserted into a guide hole 612 formed in the side wall 61 of the lid member 6, and the projection 5412 rotates the lid member 6. In response to this, the guide hole 612 slides.
According to this, the ejection bar 54 stands up in response to the rotation of the lid member 6 in the opening direction (arrow B1 direction) and the flatness of the ejection bar 54 in response to the rotation in the closing direction (arrow B2 direction). Can be performed reliably. Therefore, when the lid member 6 is in the open state, the disk 9 can be easily stored and taken out, and when the lid member 6 is in the closed state, the eject bar 54 is attached to the disk 9. It is possible to prevent the storage from being hindered.
Furthermore, the amount of rotation of the lid member 6 with respect to the bottom surface 53A can be adjusted by adjusting the longitudinal dimension of the guide hole 612. Accordingly, the size of the opening formed by the lid member 6 and the disk storage portion 53 can be easily adjusted.

(5) The disc storage portion 53 is provided with a media guide 534 on the leading end side in the insertion direction of the disc 9, that is, on the support portion 537 side. The media guide 534 has an arc-shaped portion 5341 corresponding to the shape of the semicircular portion 922 on the leading end side in the insertion direction of the shield-shaped disc 9, and when the disc 9 is stored, the arc-shaped portion 5341 The semicircular portion 922 contacts the 5341.
According to this, the disc 9 can be positioned at an appropriate position in the disc storage portion 53, and swinging of the disc 9 in the disc storage portion 53 can be suppressed. Further, when the direction of the disc 9 in the disc storage portion 53 is reversed, that is, when the disc 9 is inserted from the arc-shaped portion 923 side of the disc 9, the shape of the arc-shaped portion 5341 does not match. It can be prevented from being stored. Therefore, the turntable 532 can surely chuck the disk 9 and the pickup 533 can reliably read and write information on the disk 9 and can be erroneously stored due to erroneous insertion of the disk 9. Can be prevented.
