ABSTRACT:
A coin sorter for sorting coins in terms of their diameter includes a referencing wall engaging the radially outer edges of the coins as they are advanced circumferentially so that the radially outer edges of the coins are positioned at a preselected radial location, whereby the radially inner edges of the coins are positioned at different radial locations determined by the diameters of the respective coins. A series of circumferentially spaced exit recesses are formed around the outer periphery of a guide plate with the radially inner edges of the inner ends of successive exit recesses located at different radial positions for receiving the inner portions of coins of progressively increasing diameter. A ramp at the inlet end of each of the exit recesses slopes from the lowermost surface of the guide plate at the inlet end of the exit recess upwardly to the top surface of the exit recess for easing coins into the exit recess under the pressure of a resilient surface. The ramps preferably have a width that is less than half the width of the exit recess. A portion of the inner recess adjacent the inlet end of the spiral recess, and extending across the inlet end of the spiral recess, is spaced farther from the top surface of the disc than the lowermost surface of the guide plate but closer to the top surface of the disc than the upper surface of any pair of stacked coins carried by the disc.
