ABSTRACT:
A coin acceptor to prevent a cheating operation known as "stringing" wherein a coin is dropped into such an acceptor with a string attached and manipulated in a manner to make it appear that several coins have passed through the acceptor. This coin acceptor uses a series of coin position detectors with a counting circuit for sensing the sequence in which the coin passes the detectors.
