Next, the closing operation of the lid 30 in the open position as shown in FIG. 3 will be described. The lid 30 is manually rotated approximately 110 ° counterclockwise when viewed from the front of the lid, that is, until the lid 30 is closed. ₂ Rotate in the direction. When the lid 30 is rotated to the closed position, the gear 40 also rotates, so that the rotation lock portion 44 and the engagement concave portion 38 are engaged. At this time, as described above, since the compression spring 71 urges the gear 40 in a direction away from the disk storage unit bottom surface 14, that is, toward the engaging recess 38, the gear 40, the collar 21, and the lid 30 are urged. Are the directions in which the lid body 30 approaches the disk storage unit bottom surface part 14, that is, Z shown in FIG. ₂ Move in the direction. The rotation lock portion 44 is engaged with the engagement concave portion 38, and the lock mechanism 60 is in a state where it operates. On the other hand, the rotation urging spring 50 is in a state in which the rotation urging force for rotating the lid 30 from the closed position to the open position is accumulated. At this time, since the cushion material 20 is provided on the bottom surface portion 14 of the disk storage portion, the cushion member 20 is not damaged by the impact with the bottom surface portion 14 of the disk storage portion as the cover 30 moves. Therefore, according to the rotary lid opening / closing mechanism of the present invention, the lid can be easily opened / closed by the lock mechanism and the lock release mechanism.
[0047]
Further, in the disk drive device of the present invention, as shown in FIG. 13, the disk mounting portion 131 may be located at substantially the same height position as the device body. Even in such a positional relationship, since the lid 134 protrudes in the direction away from the disk storage unit bottom surface 132 and then rotates in a plane parallel to the disk storage unit bottom surface 132, the opening and closing operation is performed. 133 can be smoothly opened and closed without interference. By setting the disk mounting portion 131 at substantially the same height position as the device main body, the size of the disk storage portion can be made small enough to allow the disk to be mounted barely, that is, the size of the disk storage portion and Since the size of the lid can be reduced, the size of the entire disk drive device 130 can be reduced, and the selection range of the design of the disk drive device can be widened.
[0048]
Further, in the rotating lid opening / closing mechanism of the present invention, as shown in FIG. 14, the disc mounting portion 141 may be arranged at a position protruding from the device main body 140. Also in the disk drive device 140 as shown in FIG. 14, after the lid protrudes from the disk mounting portion 141, the disk 143 is opened and closed by rotating in a plane parallel to the disk storage portion bottom surface portion 142. Can be smoothly opened and closed without interfering with the operation.
