Abstract: The invention relates to a coin sorter apparatus for sorting a group of mixed coins by denomination and automatically terminating the sorting process in response to a sensed operating parameter. Sorting is provided by a stationary disk and a rotating disk positioned sufficiently proximate to one another so that when the group of mixed coins are dropped into the center opening of the stationary disk, they are rotated by the rotating disk and guided by the stationary disk on a radially outward spiral sorting path which exits each denomination of the coins at discrete locations along the periphery of the stationary disk. As the coins are sorted, a sensing device provides signals indicating the presence of a predetermined condition. A bridge guide and a diverter guide, which are part of the stationary disk, are responsive to the signals from the sensing device to redirect the radially outward sorting path of the coins to a radially inward path so as to terminate the sorting process.
