Abstract: A tape cartridge transducer machine compatible with existing tape cartridges but provided with a cartridge ejection leverage mechanism which is actuated manually or by a solenoid to overcome the cartridge-biasing spring and shift the cartridge to an inactive standby position in the cartridge receiving space of the machine, after which the cartridge is manually removable with minimum effort. The machine preferably provides a balanced cartridge-biasing means to safeguard the cartridge against binding.
