ABSTRACT:
An improved coined reel leaf spring for a video tape cassette is provided having a central portion and arms emanating therefrom. The arms include at least one rib formed therein adding strength to the arms and allowing a one-half reduction in the conventional thickness of the coined reel leaf spring required to effect bending and biasing. The reduced thickness, of course, reduces material costs for the coined reel leaf spring and overall production costs for the tape cassette.
