ABSTRACT:
An improved compact repeating slide viewer of the type having two compartments, one for storing a stack of slides and the other for viewing individual slides, a longitudinally shiftable slide carriage feeds the topmost slide of a stack to the viewing compartment and then returns the viewed slide to the bottom of the stack with the slide carriage retracting a spring actuated tongue which acts upon the stack until the viewed slide is returned to the bottom of the stack and then releases the tongue to elevate the stack for feeding of the next topmost slide. The viewer also includes means for easily loading and unloading slides from the stack or from the viewing compartment, and is constructed to be easily manufactured from molded plastic parts.
