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.
