ABSTRACT:
An improved tape cartridge release assembly for a player/reproducer apparatus of the type used in a vehicle will automatically release a cartridge when the vehicle ignition switch is turned off, will release a cartridge inserted while the ignition switch is turned off, and will release manually as desired. The assembly utilizes a pair of switches operated by insertion of a cartridge to provide identical voltages to the input and common terminals of a semiconductor circuit controlling the release actuator. The semiconductor circuit, by remaining non-conductive, will prevent release until forward biasing voltage is provided to the controlled semiconductor device as by the ignition switch, the manual release button or other means.
