Abstract

Abstract Load prevention apparatus is to be used with a film cassette which has a frangible exterior label covering a trap-like cavity in the cassette. The apparatus comprises a loading chamber configured to receive the cassette, blocking means arranged in the chamber to be admitted into the trap-like cavity for engaging the cassette to prevent further insertion of the cassette into the chamber but supported to be moved by the exterior label out of the way of the trap-like cavity to avoid engaging the cassette, and fracturing means arranged in the chamber for breaking the exterior label to uncover the trap-like cavity after the blocking means is moved by the exterior label out of the way of the trap-like cavity, whereby the blocking device will prevent insertion of the cassette into the chamber a second time.
