ABSTRACT:
An automatic viewer for half-frame stereoprints includes a base with a pair of lenses for stereoscopic viewing mounted thereon. The base has a kicking foot and picking detent projecting therethrough for engaging openings in a carrier deck upon which the half-frame stereoprints are pivotally mounted. A control mechanism utilizes cams to coordinate movement of the kicking foot and picking detent to index the carrier deck across the base so that the photoprints may be viewed individually. The carrier deck has two rows of openings for receiving the kicker foot, allowing the viewer to advance the carrier deck from either end presenting a first set of photoprints for viewing when advancing from one end and a second set of photoprints for viewing when advanced from the opposite end. The carrier deck may be stored with other carrier decks in a binder.
