ABSTRACT:
A stereogram viewing apparatus comprises a box having a cover pivotally attached thereto for pivotal movement between open and closed positions. A stereogram accommodating part holds a set of stereograms at the front of the inside of the cover. A foldable plate is disposed in the box and is provided with left and right eyepieces. The plate is foldable into a folded state to fit within the box to permit the cover to close and is movable to an unfolded state in which the plate positions the eyepieces frontward of the stereograms to enable a user to view the stereograms through the eyepieces. When the cover is in the upstanding open position, the box may be pivoted downwardly and rearwardly to an upside-down position to support the apparatus on a surface while the upstanding cover faces frontward. In this manner, the apparatus can be conveniently placed on a surface, such as a desk or the like, so that the stereograms may be viewed by a user without having to hold the apparatus in his hand.
