Abstract

Abstract An automatic phonograph includes a record magazine and a carriage mounted for movement relative to the record magazine and having means for removing an individual record from the magazine, clamping the record to a turntable, playing the record, and returning the record to the magazine. Record selection means enable the operator to select sides of particular records for the playing thereof. To store and read out information concerning the selected records, there are provided a memory unit, a readout unit and a circuit actuable by the readout unit to align the carriage serially opposite selected records. The memory unit includes a plurality of pins corresponding to the sides of records and which are actuated in response to a signal from the record selection means and a cam track. The readout unit is mounted on the carriage and includes a cam follower adapted to ride on the cam track of the memory unit and a contact member on a sensing lever operatively associated with the cam follower. The contact member is adapted to engage an actuated pin to complete the circuit so that the carriage is aligned with the record corresponding to the pin in the actuated position.
