ABSTRACT:
An x-ray film has a flexible sheet having a front face and a rear face, a layer of an x-ray stimulable phosphor on the front face, and a layer of mangetically attractable material, for example a steel foil, on the rear face. This film is used with a film handling apparatus, normally a reader, having structure forming a flap support surface of a size at least equal to that of the film and at least one permanent magnet is imbedded in the structure and extends over the surface. Thus the rear face of the film can be adhered magnetically to the surface. An array of stripping elements is distributed over the surface and each element is displaceable through the surface between a recessed position below the surface and an advanced position projecting past the surface. An actuator can displace the elements from their withdrawn to their advanced position and thereby lift from the surface a film clinging magnetically to the surface.
