Abstract
In an automatic tape cartridge loader, separating the tape from the drive motor during unloading often imposes a high torque requirement on the loader motor, for example to overcome magnetic forces strengthening engagement of the cartridge to the motor. The inventive loader utilizes one or more techniques to assist in separation of the cartridge from the motor gear. One technique involves two compression springs on the base, which apply a force opposing movement of the cartridge shuttle to its cartridge-loaded position and assist in movement of the shuttle from that position during unloading. Another technique utilizes a special cam and follower arrangement to apply different lifting forces on opposite sides of the shuttle, at least during initial movement to unload the cartridge.
