Abstract
An apparatus for detecting fraud in a coin detector is disclosed. The apparatus is provided with a coin validating device. A coin sensing apparatus, located downstream of the coin validating device and preferably including a plurality of optic emitter-detector pairs arranged to detect the passage of the coin, is also provided. The coin sensing apparatus is adapted to provide improved resistance to miscounting of coins and to traditional gimmicks used to cheat coin operated devices such as tilting the coin detector.
