发明名称 EPISKOP MED ANORDNING FOR BILDVEXLING
摘要 A device for displaying sheet opaque pictures in which images of scenes thereon are transmitted from a housing onto an exterior display. A picture exchange magazine has a display window at the picture scene such that the top of a stack of pictures is confined at the window and the remainder are confined behind it. The magazine includes first and second frame members, the latter being relatively reciprocable parallel to the window and picture scence for cyclic exchange of the top picture in the magazine. A release holder retains the magazine on the housing while allowing the frame members to remain relatively movable to each other.
