<p>Coin testing apparatus for testing coins of plural denominations which initially tests each coin electronically by means of a probe. According to the denomination of coin indicated by the electronic tests, a mechanically operating sorter which corresponds to this denomination is energized to check that the mechanical properties of the coin correspond to this denomination. Thereafter a counter is operated. Whenever a bad or non-genuine coin is detected, the movement of all coins is blocked so that even succeeding good or genuine coins will not be processed until the bad coin is removed. Alternatively, coins which fail the electronic test are rejected by falling past a member which only moves into position to intercept or guide coins which have passed the electronic test. Timing stages delay the energization of a corresponding mechanical sorter for a timed period after the electronic test to allow time for a good coin to reach the mechanical sorter and for a preceding bad coin to pass by.</p> |
