Patent ID: 7958520

Claim:
A disk drive device comprising: a rotary arm rotatable in accordance with loading of a disk between a draw-in position and an eject position where the disk is ejected out of a housing; a drive mechanism that provides a driving force for the rotary arm; a link arm mechanism that connects the rotary arm and the drive mechanism to each other, and rotates the rotary arm from an insertion position to the eject position at the time of ejecting the disk; a deck arm disposed substantially across from the rotary arm relative to a disk insertion direction that, together with the rotary arm, prevents an erroneous insertion of a small-diameter disk and performs centering with respect to the disk at respective positions around a circumference of the disk; and a guide cam having a guide edge on which a guide projection provided in the link arm mechanism slides at the time of ejecting the disk to cause the rotary arm to rotate in an ejecting direction via the link arm mechanism, the guide projection moving around the guide cam from insertion to ejection of the disk, wherein when a force directed opposite to a rotation direction is applied to the rotary arm at the time of ejecting the disk, engagement between the guide projection and the guide edge is released.
