<p>A compact, low power gate apparatus for use in coin operated machines, such as coin operated telephones, utilizes an inclined diverting surface and adjacent, coupled levers to decrease power requirements, multiply displacements and save space. A selectively energizable solenoid associated with a first lever moves the levers from a first to a second position when the solenoid is energized, and maintains them in their first position until the solenoid is energized again. A restoring means restores the levers to their first position when the solenoid is no longer energized and maintains the levers in their first position until the solenoid is energized again. The second lever has a coin diverting plate which is selectively positioned to divert a coin to a particular path or allow the coin to continue along the same path. The inclined diverting surface has an angle such that the component of force due to a falling coin impacting the surface is directed toward the pivot point of the second lever, decreasing the restoring force required to maintain the second lever in its first position, thereby decreasing the power requirements of the solenoid. The apparatus can reject coins in a passive mode and accept coins in an active mode. A microprocessor controls the selective energization of the solenoid by controlling a specially designed power supply and.power application control circuit for low power operation from power supplied from a phone line.</p> |
