Abstract
A coin sorter having a rotatable disc includes a brake mechanism for stopping rotation of the disc in response to a predetermined number of counted coins. The disc is driven through a gear train by an electric motor. The brake mechanism includes a first brake mechanism coupled to the motor for stopping rotation thereof, a second brake mechanism coupled to the coin disc for stopping rotation thereof, and a control mechanism for operating the brake mechanisms in a synchronous manner so as to avoid any shock loads upon the gear train due to existence of torque differentials on either ends thereof. The brake mechanisms are adapted to have substantially identical stopping times and are operated in such a manner as to be energized in a substantially instantaneous manner when the braking sequence is initiated.
