  • Abstract:
    A token operated control system for use with a multitrack tape cartridge player which enables a priori manual selection of a single track from one or more tape cartridge players for reproduction and which provides automatic termination of track reproduction at the end of a given track. Interruption of track reproduction, once reproduction has begun, is prevented by the control system circuitry. The control system is compatible with several commercially available eight-track tape cartridge tape players and includes additional circuitry for sequentially arriving at a single track of a given cartridge player unit specified by manual operation of panel switches after the insertion of a token, e. g. , a coin.
