Zusammenfassung: | An electronic selector system operable to transmit multi-train pulse signals representative of record selections to an automatic photograph at a remote location. The selector system generally comprises a plurality of selectively operable pushbutton switches representing selection digits, electronic pulse train counters each operable when connected to an electrical pulse generator to count a train of a preset number of pulses and electronic circuitry for presetting the counters in coded correspondence with operation of the pushbuttons. Record selections represented by individually identifiable multi-train pulse signals are each preconditioned upon operational sequencing of the pushbuttons according to predetermined digit combinations. |
