Abstract
A 3-D film projection apparatus includes two projectors that are disposed side-by-side in closely adjacent positions during projection. Each projector is carried by a transporter so that it can be moved to a retracted position rearwardly and laterally outwardly with respect to the other projector for providing access to the projector for set up and maintenance. Preferably, the transporters are motorized and the apparatus includes film guide means for maintaining a film path between each projector and an associated reel unit during transportation of the projector between its projection position and its retracted position.
