An apparatus for opening radiographic cassettes comprises a housing which may be closed in a light-tight fashion and containing a platform onto which the radiographic cassette is positioned. Also, in the housing is an elongated upwardly inclined cam surface which engages a lip portion projecting from the cover of the cassette. When pushing the cassette further into the housing the cover becomes gradually lifted by the cam action. At a given position the cover is lifted sufficiently open to permit the introduction and removal of unexposed and exposed film into and out of the cassette. A release mechanism, upon actuation, enables the cassette cover to drop thereby closing and relocking the cassette. The apparatus is suitably incorporated in a daylight system for loading radiographic cassettes with unexposed radiographic films.
An apparatus for opening radiographic film cassettes which comprises a housing and in said housing a platform for the introduction and withdrawal of the radiographic cassette into and from said housing, guide means for engaging a longitudinal edge of said cassette for aligning the cassette relative to said platform during its introduction, stop means for precluding further movement of the cassette when it has advanced to a predetermined location in said housing, and a cam surface is inclined inwardly relative to said platform with its lowermost end in the path of a laterally projecting lip portion of a cassette cover as the cassette is advanced relative to said inclined cam surface so that the cassette cover becomes progressively opened during its introduction into the housing.
