Abstract
A stereo slide viewer can appreciate a stereo image without cutting a roll film photographed by a stereo camera. A film feeder 3 for feeding a roll film F is mounted at the rear of a table 2 of the stereo side viewer 1, and a pair of right and left projection lenses 5R and 5L are provided at the intermediate of the table 2. A pair of right and left focal plates 9R and 9L are mounted at the front of the table 2, and eyepieces 11R and 11L are installed oppositely at the focal plates 9R and 9L. The back surface of the film feeder 3 is illuminated by an illuminator, and one set of images are focused on the right and left focal plates 9R and 9L through the windows of the film feeder 3.
