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.
In an electronic phonograph selector and memory system the combination comprising:
In an automatic phonograph adapted to play a multiplicity of selections identified by respective multidigit numbers and having credit registering means which produces a credit signal indicating the existence of a credit equalling at least the price of a play, apparatus for visibly displaying the number of a selection including,
In an automatic phonograph having a playing unit adapted selectively to play a multiplicity of selections identified by multiple-digit numbers in response to input signals representing said numbers and to produce an output signal representing a selection presently being played, said input signals being of the same character, and having credit registering means which produces a credit signal indicating the existence of a credit at least equal to the price of a play, a control circuit providing digital information corresponding to the number of a selection a keyboard having a plurality of manually operable devices adapted to be actuated to provide a multiple digit selection signal, means normally coupling said playing unit output signal to said control circuit to provide digital information corresponding to the number of a selection being played, means responsive to said credit signal and to actuation of a number of said devices corresponding to the number of digits in a selection identification number for deactivating said output signal coupling means and for coupling said selection signal to said control circuit to provide digital information corresponding to the number of a selection to be played.
In an automatic phonograph having a playing unit adapted selectively to play a multiplicity of selections identified by multiple-digit numbers in response to transmitted selection signals representing said numbers, said selection signals being made up of a plurality of digit signals correspondng to the number of digits in a selection identification number, and having credit registering means which produces a credit signal indicating the existence of a credit at least equal to the price of a play, apparatus for selection and display of the number of a selection including
