Disk cartridge loading apparatus for use in recording/reproducing device

Claim 1

A recording and reproducing apparatus comprising: a cartridge holder adapted to accomodate a disk cartridge inserted therein, said cartridge holder having a roller affixed on a side portion of said holder and being movable in said apparatus between unloaded and loaded positions by movement of the roller in a backward horizontal and a downward vertical direction; a resilient member for normally biasing said cartridge holder toward the unloaded position toward a front side of said apparatus, said cartridge holder being movable in the backward direction toward a back side of said apparatus against the biasing force of said resilient member and in the downward vertical direction to the loaded position; and a movable cam member having a horizontal portion for contacting and guiding said roller on the horizontal backward movement and an inclined portion adapted to abut said roller on the downward vertical movement of said cartridge holder to the loaded position and to return said cartridge holder to the unloaded position upon an ejection movement of said cam member wherein said inclined portion pushes said roller and cartridge holder upward vertically, said cam member being formed with a projecting portion smaller than the diameter of said roller and located adjacent to an intersection of the horizontal and inclined portions of said cam member, so that said roller makes a click contact and moves over said projecting portion during its backward horizontal and downward vertical movement to the loaded position.
