摘要： Disclosed herein is a recording medium drive apparatus adapted to use a recording medium cartridge. The recording medium drive apparatus includes a holder for holding the recording medium cartridge inserted, an eject lever supported to one of a pair of side plate portions of the holder so as to be movable in an inserting direction and ejecting direction of the recording medium cartridge with respect to the holder, and a biasing spring for biasing the eject lever in the ejecting direction. The eject lever has a supported portion supported to the one side plate portion of the holder and an engaging projection projecting from the supported portion toward the other side plate portion of the holder. When the recording medium cartridge is inserted into the holder, the engaging projection is inserted into an engagement groove of the recording medium cartridge and engaged with an engaging portion formed in the engagement groove. When the eject lever is moved in the ejecting direction by a biasing force of the biasing spring in the condition where the engaging projection is engaged with the engaging portion of the recording medium cartridge, the recording medium cartridge is ejected from the holder.

摘要： A recording and/or reproducing apparatus includes a base member at least having a rotation driving mechanism for rotationally driving a disc housed in a disc cartridge, a holder into which is inserted the disc cartridge and an ejection lever formed by an elastically flexible lever. The holder is mounted for movement between a first position in which the disc inserted in the disc cartridge is loaded on the rotation driving mechanism and a second position in which the disc housed in the disc cartridge is spaced apart from the rotation driving mechanism. The second position is higher in level than the first position. The ejection lever is elastically flexed by the disc cartridge inserted into the holder from a position protruded into the holder to the position extending along the back side of the holder. When elastically flexed to the position extending along the back surface of the holder, the ejection lever is engaged with the holder moved to the first position. When the holder is moved from the first position to the second position, the ejection lever is disengaged from the holder and is elastically restored in the direction of being intruded into the holder to eject the disc cartridge from the holder.

摘要： 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.
