ABSTRACT:
A reel mechanism for use in a playing device comprises a DC motor having a rotor formed with an outer apron on which are displayed a plurality of substantially equally spaced symbols which are to be sequentially displayed in a visual field. The rotor rotates about the stator with the rotor having permanent magnetic poles which interact with the stator. The apron has a plurality of perforations or recesses associated with the individual symbols which are scanned by a plurality of photo-transistor scanning devices so as to generate for each symbol upon its passing of a particular position unique information scanning signals which identify each of the symbols. These scanning signals through a switching arrangement provide pulsing signals to the DC motor for energizing the magnetic field within the stator to control the commutation of the DC motor in pulsing synchronization, with the scanning signals effecting rotational motion of the rotor while at the same time being indicative of the position of the rotor and the respective symbol displayed in the visual field.
