ABSTRACT:
Disclosed is a stereoscope apparatus comprising a left and right reflective sheets converging, in upright position at a predetermined angle in the range of 40 to 50 degrees, towards the line of sight of the viewer so that the left eye sees only the left reflective sheet and the right eye sees only the right reflective sheet. A pair of holding means for the pictures or images are disposed relative to the reflective sheets at angle of 40 to 50 degrees whereby the pictures or images held therein are simultaneously reflected to the respective left and right reflective sheets. The pictures or images are the corresponding left and right eye views of the pictures or images intended to be viewed. When viewed, the reflective sheets acting as the screen, imparts a three dimensional effect upon the eyes of the viewer. Enclosing walls, forming a box-type structure confine the reflective sheets and the holding means. On the sides of the holding means are compartments to contain a plurality of the left eye views and the rights eye views of the pictures or images queued up for viewing.
