Coin accepting device
First Claim
1. A detector for sensing the passage of a coin having a leading and a trailing edge along a predetermined path, comprising, in combination,a plurality of sensors spaced along the path with each sensor including signal generating means for indicating the arrival of the leading edge of the coin at the sensor position and passage of the trailing edge of the coin past that sensor position;
- means for transmitting said sensor signals in sequence;
means acting in response to the occurrence of said signals for indicating the uninterrupted passage of the coin past the sensors when the signals are in one predetermined sequence; and
means for indicating the interrupted passage of the coin past the sensors when the signals are in a second sequence.

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.

6. A detector for sensing the passage of a coin having a leading edge and a trailing edge along a predetermined path, comprising, in combination,
a plurality of sensors each spaced along the path with each sensor including means for generating signals indicating the arrival of the leading edge of the coin at the sensor and thereafter the passage of a trailing edge of the coin therepast; -
switching means receiving said sensor signals in sequence and for closing a first circuit when the sequence of said sensor signals is in one predetermined order indicating the uninterrupted passage of the coin past the sensors and for closing a second circuit when the sensor signals are not in said predetermined order indicating the interrupted passage of the coin past the sensors; first indicating means acting in response to the closing of the first circuit for signaling the passage of a coin past the sensors in an uninterrupted manner; and a second indicating means acting in response to the closing of the second circuit for signaling the passage of a coin past the sensors in an interrupted manner. - View Dependent Claims (7, 8, 9)

10. A detector for sensing the passage of a coin along a predetermined path, comprising, in combination,
a plurality of sensors positioned along the predetermined path, each sensor including means for signaling the alignment of a portion of the coin with that sensor; -
a plurality of switches electrically connected to be actuated in succession upon the receipt of a sequence of said sensor signals, said switches being connected to close a first circuit when the signal sequence is in a first order and being connected to close a second circuit when the signal sequence is in a second order; and indicating means for signaling the closing of one of said first and second circuits thereby indicating the sequence in which a coin aligns with said sensors. - View Dependent Claims (11)
