ABSTRACT:
An automatic selector unit for repetitively actuating an automatic phonograph to play randomly selected records includes a first timer for measuring the elapsed time since a previous play and a continuously running second timer for generating periodic pulses. The unit actuates the scanning mechanism of the phonograph after a predetermined elapsed time to bring different records successively into position for play and thereafter actuates the player mechanism on the next pulse from the second timer to play the record then in position for play.
