Abstract
The embodiment of the invention disclosed herein is directed to an electronic phonograph selector and memory system which enables the selection of records to be played after the proper amount of credits have been accumulated in a coin accumulating circuit. The system has a movable record carriage for placing a desired one of a plurality of records at a playing location. The record carriage is transported by receiving a drive signal indicating that a new carriage position is required. The code signal information is compared so that when the carriage is at its desired location the search signal is removed. The movable carriage has a position encoder so that binary code signal information corresponding to the various positions of the carriage can be detected and compared to the codes stored in a random access memory circuit.
