Abstract

A photobooth and indexing system that includes a square frame having a motor driven film pack conveyor disposed about its periphery. The conveyor comprises 22 trays; 21 hold film packs and one holds a dummy pack. When a tray is indexed into position under the motorized film pack support, a ram lifts the pack up to an exposure position. A motorized support includes a rotatory solenoid operated pack, a pair of motor driven rollers and a film deflector for spread control. A logic system causes the dark slide to be automatically ejected into a film delivery chute. After 10 exposures, the logic causes the ram to be lowered thereby returning the empty pack to the underlying tray. The conveyor is indexed one tray position and the procedure is repeated. When the last tray arrives at the ram station, the dummy pack is elevated by the ram causing the logic to inhibit further operation of the photobooth until it has been reloaded with fresh film.
