Abstract
Mechanism for repositioning one of a set of symbol-displaying spinning reels in game apparatus to change the symbol display. A reel-stepping gear with yieldable jambproof overload-responsive driving components changes the position of the reel by coaction with an associated code disc to step the reel in either direction once per duty cycle of the gear and change the position of the reel by an angular amount equal to the spacing of the symbols thereon, while also releasing the existing reel-indexing mechanism so the reel is free to move and then re-indexing the reel in its new position once in each duty cycle. Free-wheeling of the released reel is prevented during the repositioning operation by an automatic brake. Any number of duty cycles may be initiated to change the position of the reel a corresponding number of steps in a given game cycle.
