Abstract
The present invention relates to a gaming machine having mechanical spinning reels and display units mounted inside the reels that are driven between a retracted position and a forward position. The display unit is displaced inwardly toward a central axis of the reel when located in the retracted position, and in this position the reel is free to rotate in response to a wager being placed. The display unit is located closer toward the outer periphery of the reel when in the forward position and in registration with a variable display when the reel is stopped. Movement of the display unit between the retracted and forward positions minimizes parallax effects and increases enjoyment for a player.
