Abstract
A cartridge holding mechanism, for a magnetic tape cartridge apparatus, includes a cartridge holder having guide rollers rotatably supported thereon for holding a magnetic tape cartridge housing. A base plate having guide grooves is provided for guiding the guide rollers to move the cartridge holder vertically. A bottom lever is rotatably supported by the base plate and has first ends formed with grooves which are engaged with the guide rollers, and an opposite end rotatably supporting a cam roller. A cam drum is rotatably supported by the base plate and has, on a surface thereof, a cam groove engaged with said cam roller and, on an upper portion thereof, a drum gear. The mechanism further includes a load motor having a motor gear meshed with the drum gear for driving the cartridge holder.
