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.
