Abstract
A pair of light-shielding film cases of similar construction, such as may be used in a surveillance camera, having a simple construction but providing improved film running performance. The light-shielding film cases accommodate a film supplying spool on which a film has been wound and a film winding spool on which the film is taken up. At least one roller is provided in each of the film cases. The film cases each have a cover and a winding knob, the latter also serving as a spool bearing and being mounted on a respective one of the covers.
