发明名称 Separable film spool and method of loading film cassette therewith
摘要 A two-piece spool is disclosed for winding of a flexible strip and includes a pair of interconnected members having flanges. One of the two members has a tongue extending from the flange thereof and the other has means for slidably receiving the tongue. The receiving means includes structure responsive to sliding engagement with the tongue for forcing the tongue into a flexed condition from an initial condition to retain the members in their interconnected arrangement. A method is also disclosed for allowing manual loading of unexposed film wound on a spool in a film cassette by using separable spool members including a separable cover.
