Abstract
Abstract A coin singulator for outputting coins in single file in a known orientation for effecting payout from a gaming terminal is provided. A rotatable disk is positioned spaced-apart from a backplate to define a substantially cylindrical region therebetween in conjunction with a rim region. Vanes on the front surface of the rotating disk convey coins picked up from a randomly-oriented mass of coins to a central opening of the disk for conveyance through the central opening into the space between the disk and the backplate. The distance between the disk and the backplate is such that only a single layer or thickness of coins is accommodated. Preferably the backplate is inclined such that the coins are positioned in face-to-face contact with the backplate. A plurality of vanes on the back surface of the disk moves the coin along the rim to an exit opening in the rim with the back surface vanes preferably shaped to output no more than a single coin as each rim passes the opening. The device can accommodate a range of coin or token sizes thus reducing the number of configurations or parts to be kept in inventory.
