ABSTRACT:
A floppy disc recording and/or reproducing apparatus comprises a loading mechanism which has a support member which is fixed to the frame and has cam levers pivotally supported thereon, where each of the cam levers have a second cam part, a cartridge holder which has a first cam part and is arranged movable in upward and downward directions of the apparatus under guidance of the support member, and a push-eject member which has third and fourth cam parts and an ejecting push-button. The push-eject member is movable in frontward and rearward directions of the apparatus under guidance of the frame or the support member. A sequence of operations are carried out when a cartridge which accommodates the floppy disc is placed onto the cartridge holder so as to load the cartridge with respect to a driving shaft. The sequence of operations includes an operation in which the cam levers are directly or indirectly rotated by the cartridge, an operation in which the push-eject member is moved in the frontward direction of the apparatus due to an interaction between the second and fourth cam parts, and an operation in which the cartridge holder is moved in the downward direction of the apparatus due to an interaction between the first and third cam parts.
