Abstract

Apparatus for copying the images of selected frames on sections of exposed and developed roll films or of diapositives has a set of advancing rolls or a reciprocable pusher to move a film section or a diapositive from a discrete first portion of a first path into a second portion which terminates at the copying station, and thereupon from a first portion of a second path (such first portion is common to the second portion of the first path) into a discrete portion of the second path. A switching device is located at the junction of the first and second portions of the first path to prevent copied film sections or diapositives from reentering the first portion of the first path on their way away from the copying station. This renders it possible to introduce a fresh film section or a fresh diapositive into the first portion of the first path while a film section or a diapositive is located at the copying station or is on the way toward the discharge end of the second path.
