ABSTRACT:
The back of a camera has a window through which an information area on a film cartridge may be viewed. One of the ends of an elastic opaque strip is connected to the camera back at a location between the window and a film pressure plate supported on the camera back. When the other end of the strip is moved to draw the strip taut, partially about the cartridge, the strip transversely shifts against the cartridge and positions an opening in the strip, aligned with the window, over the information area on the cartridge. The strip thus forms a light-tight connection between the camera back and the cartridge, which prevents light entering the window from fogging film advanced out of the cartridge.
