COIN DISCRIMINATOR ABSTRACT OF THE DISCLOSURE An apparatus for discriminating between coins of different value by determining their sizes. The coin discriminator includes a two-dimensional, coin-measuring array of optical sensors arranged to establish predetermined coin-measuring boundaries, a channel for guiding coins past the coin-measuring array, and circuitry for determining when a coin has been guided by the channel to a trigger point where its diameter can be measured by the sensor array. When a coin approaches the trigger point, the circuitry activates the sensor array. Then, when the coin reaches the trigger point, the circuitry triggers a measurement circuit which identifies the size-and value-of the coin by sampling the activated sensor array to determine the furthest measurement boundary from the trigger point that is crossed by the coin.
