摘要： Coins corresponding to a payment, thrown into a hopper, fall on a recessed disk and each lodge in one of the recesses. If two coins are superposed in one recess, the upper coin is deflected outwardly by a slot and then raised by the inclined bottom of this slot to finally be ejected from the recess. The coins are then, as a function of the result of a detection, oriented toward one or the other of two compartments of an annular display which surrounds the separation disk. At the end of each payment, the annular display turns a fraction of a turn to bring the two compartments into a presentation position, while two empty compartments are presented to receive the following payment, and the coins corresponding to the preceding payment arrive at a transmission position for example toward collection boxes. The drive of the movable portion of the display is effected by its radially outer edge. The central portion comprising the separator disk and its drive motor can swing downwardly to eject foreign bodies In case of a questioned coin, or if the movable portion of the display is in the course of rotation, the coin is returned to the detector instead of proceeding to the display.

摘要： Device for checking metal disks and especially coins, characterized in that it comprises a sorting mechanism essentially constituted by a single motor-driven circular plate 4 which makes it possible to carry out simultaneously the functions of separation and identification of coins, this plate being toothed around its periphery and reinforced at the center by a portion 9 of frusto-conical shape onto which the coins fall in a bulk admission zone. This plate rotates above a stationary portion 2 which is almost entirely surrounded by a circular rim 3 on which the coins slide when they are engaged between the teeth of the plate. Provision is made for the identification and authentication of coins, which take into account both the material, the thickness and the diameter of these latter, including a single electromagnetic detector 15 placed above the plate 4. The detector is eccentric to the path of the centers of the coins, so that variation in the diameters of the coins can be detected.
