The present invention relates to a rotary disk loading mechanism. A disk loading mechanism according to the present invention includes a recording medium holder which is rotatably supported by a chassis and into which a storage medium such as a mini disk (trademark) or the like is inserted, an eject lever as a rotation operation member disposed on one side of the recording medium holder and movably supported by the chassis, an operation converting means formed of a cam and so on for converting movement of the eject lever into rotation of the recording medium holder, a holder locking member rotatably provided on the chassis and biased by a first springy member, and an engagement portion provided on the eject lever and biased by a second springy member in a predetermined direction to thereby be engaged with the holder locking member. When the holder locking member is brought in contact with the storage medium to be inserted into the recording medium holder and thereby rotated against a spring force of the first springy member, a relief surface provided on one of the holder locking member and the engagement portion is brought in contact with the other thereof and release of engagement of the holder locking member and the engagement portion is started early as compared with release of the engagement prevented when no relief surface is provided. Thus, it is possible to provide a loading mechanism which improves operability upon insertion of the storage medium.
