Title: Electronic coin switch

Abstract: A coin switch for coin operated vending machines, especially juke boxes, in which a coin, after it has been successfully passed by a slug rejector, drops through a chute according to its denomination and interrupts a light beam falling on a photo-sensitive device, specifically a photo transistor. Different chutes or passageways are provided for coins of different denomination, and the chutes are so configured as to limit the speed of passage of a coin whereby to insure production of a modulated signal of recognized character of usable width. Such signal is conveniently a D.C. pulse.
