ABSTRACT:
A device for viewing a series of stereoscopic views disposed in pairs in columns on a card (S) comprises a generally flat rectangular body (9). A first pair of channels (14) on the front of the body, disposed on each side of an axis of symmetry of the body, is adapted to permit the card to slide therein. A hinged plate (16) carries eyepieces (30, 31) and is hinged (17 to 20) to form panels (21 to 25). An end panel (24) is attached to the body (9). The other end panel (25) is mounted so as to slide in the second pair of channels (15). The center and lateral panels (21, 22, 23) occupy either a deployed position in which the eyepieces (30, 31) lie in a plane parallel to and appropriately spaced from the front surface (10) of the body (9), in line with windows formed in the body, or a folded position in which the plate (16) lies flat against the front surface (10).
