<p>The selector for automatic coin receiving appts. includes a dihedron at the end of a channel into which the coins are introduced. The dihedron has a rectilinear angle slightly less or equal to a right angle. Two large faces are matched to the diameter and thickness of the coins. The dihedron is inclined transversely and longitudinally so that coins slide under the influence of gravity urged against the first face, and rolling along the second face in the groove formed. A channel under the dihedron collects all the incorrect coins rejected by the selector.</p> |
