ことを特徴とする立体画像再生装置。 A positive lens part whose focal point is the center of a baseline connecting both eyes at a scheduled observation position in a baseline cross section including the baseline, and a first prism and a second prism, which are arranged in parallel along the baseline direction. The first prism includes a first input surface facing the first image, and an inner surface that is in contact with an air layer and directs a portion of the light flux from the first image to the positive lens side. the second prism has a first slope for reflection;
A second input surface facing the second image and the first slope face the first slope with an air layer in between, and transmit a part of the luminous flux from the second image to the first prism. and a second slope for making the light incident on the positive lens, and the first and second slopes are arranged so that the light flux from the first image and the light flux from the second image are separated from each other by the optical axis direction of the positive lens within the baseline cross section. A three-dimensional image reproducing device, characterized in that a critical angle is set so that the positive lenses are incident on the positive lens at different angles.
