Apparatus for receiving and reading a cassette of light-sensitive material, wherein the cassette is a) of varying width and b) free of a pallet used to fit a standard maximum width slot. To prevent light-leaks created when a cassette of a width less than the maximum is used, shutters equal to one less than the number of cassette widths to be used, are hinged to one of the upper and lower jaws used to clamp the cassette in the light-tight chamber of the reading apparatus.
