摘要： The invention relates to a slide projector with automatic slide changer and stationary slide magazines (10,11) on each side of the optical pathway of the projector, the respective slide magazine (10,11) provided in the shortside with a feed and discharge opening for slide frames (8) which is located in the focal plane of the slide projector. Between the slide magazines (10,11) a slide frame transport device is located, which consists of two toothed belts (2,3) provided with external dog members (7) for transporting the slide frames (8) from one slide magazine (10) to the other (11), and vice versa. In the projection position of the slide projector support members (12,13 and, respectively, 16,17) facing to the toothed belts (2,3) are provided for the slide frames (8). Levers (20,21) are provided behind the toothed belts (2,3) directly in front of the respective slide magazine (10,11) for inserting the slide frames (8).
