<p>A device for accumulating coin credits corresponding to the denomination of coins inserted into a coin responsive machine rendering the machine operative when a predetermined total of coin credits have been accumulated. Each deposited coin actuates an associated solenoid causing an angular displacement of a coin determinative pawl actuator proportional to the denomination of the inserted coins. The angular displacement of the pawl actuator causes a switch actuator to disengage motor switch activating a motor. The motor, by a gear linkage, rotates a registering gear through the same angular displacement as the pawl actuator, thereby "tracking" the rotation of the pawl actuator through the same angular displacement until the switch actuator deactivates the motor. The gear linkage also moves the wipers of a rotating switch across a circular configuration of switch contacts to the contact corresponding to the denomination of the inserted coin. This operation is repeated for each inserted coin thus moving the wiper to a new contact representing the accumulated total of coin credits inserted until the wipers reach a predetermined contact representing a total accumulation of coin credits necessary to render the machine operative. After the operation of the machine, the associated solenoids operate automatically to cause the sequential rotation of the pawl actuator and the corresponding operation of the motor until the wipers of the rotating switch are returned or "homed" to the original rest position.</p> |
