Abstract: A stimulable phosphor sheet stacking tray comprises a tapered section for aligning stimulable phosphor sheets at a predetermined position, which is positioned at least at an inner wall of one side end face of the stacking tray where a lower end portion of the stimulable phosphor sheet falling by the sheet weight passes through. Or, the stacking tray comprises a sheet holding member positioned for contact with upper ends of the stacked stimulable phosphor sheets between an inner wall of an upper end face of the stacking tray and the upper ends of the stacked stimulable phosphor sheets, and a system for moving, by operation from the exterior, the sheet holding member to and away from the stacked stimulable phosphor sheets. Or, the stacking tray is provided with a sheet fall preventing member comprising a stopper projectable from the center of a side end of the opening face of the stacking tray to the inside of the opening face to prevent the sheet falling, and a member for supporting and moving the stopper.

Abstract: A device for containing a radiation recording medium includes an opening through which the recording medium is placed and a light shutting plate for closing the opening to prevent light from penetrating into the casing. A light shutting plate is provided integral with a handle. A locking mechanism is provided for bringing a casing into locking engagement with the light shutting plate. Since the device is moved by holding the handle with the light shutting plate locked on the casing, there is no possibility that the film will be inadvertently exposed to light with the shutter plate left unclosed.
