ABSTRACT:
A count mechanism for a dispensing machine which delivers coins in a single file along a track has a star wheel in the path of travel of the coins. The star wheel is indexed one point for each coin which passes it. The star wheel can be locked against rotation by a latch which engages a point on the wheel and which is held disengaged by a first solenoid. A second solenoid assists in disengaging the latch from the star wheel. A spring biased pawl rides the periphery of the star wheel between points to prevent free rotation. The star wheel is provided with spaced reflective areas on its top surface and a pair of spaced optical sensors detect the presence and absence of reflective surfaces as the reflective areas pass beneath the sensors. The optical sensors generate a pair of out-of-phase pulses which are employed to count the coins. A mechanism is also provided to test for dirty conditions of the star wheel or optical sensors.
