Abstract
A cassette for a stack of superimposed sheets of X-ray film has a bottom wall, four sidewalls disposed at the upper side of and defining with the bottom wall a rectangular or square chamber for at least one stack of sheets, and a cover which is pivotally connected to one of the sidewalls and is movable between an open position to afford access to the chamber and a closed position in which it cooperates with the sidewalls to prevent penetration of light into the chamber. The top surface of at least one sidewall is provided with one or more markers (e.g., in the form of a row of triangular indicia) made of or containing a material which permits ready visual detection of the marker in a darkroom whereby a person looking at the marker can ascertain at a glance whether or not one or more uppermost sheets of a stack in the chamber are misaligned so that they overlie the top surface or surfaces of one or more sidewalls and must be reoriented prior to pivoting of the cover to closed position. Such pivoting of the cover to closed position could result in damage to the misaligned sheet or sheets.
