Abstract
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.
Claims7
Apparatus for receiving cassettes containing light-sensitive members in a light-tight chamber, each of said cassettes having one of a number of possible predetermined widths, the apparatus comprising:
- upper and lower jaws for holding a cassette in place between the jaws,
- a single pair of upright guides spaced apart a distance sufficiently equal to the width of the largest-width cassette so as to provide some light-shielding when one of said largest cassettes is in said chamber, said jaws being movably mounted between said guides and said guides defining between them a dimension equal to the maximum width of said cassettes receivable within the apparatus,
- a plurality of shutters hingedly mounted on one of said upper and lower jaws between said upright guides, and
- a slot for each of said shutters, mounted within the other of said upper and lower jaws and having the same length as, and a location opposite to, said each shutter,
- said shutters being disposed so as to swing into said opposite slot to close the gap between said jaws in the absence of a cassette,
- said shutters being free of a fixed divider between them so that a cassette of a width equal to said dimension of maximum width measured between said guides can be inserted between said jaws to force all of said shutters open.
