Carousel slide projector - Wikipedia, the free encyclopedia |
 | | A carousel slide projector is a common form of slide projector, used to create slideshows. |
 | | A separate, circular tray holds several slides (usually 20, 36, 80, or 140) 35mm slides, and is filled with each slide placed in upside down and backwards, so that the image is presented with the correct orientation. |
 | | As the projector is advanced, a reciprocating mechanism pushes the currently loaded slide back out into the tray, then the tray is rotated, dropping the next slide into position between the light source and lens. |
