ABSTRACT:
A spring includes a central mounting portion mounted to an inner surface of a cassette housing and elongated pressure portions extending from the mounting portion to engage the cassette reels. Each pressure portion includes a central base and a pair of spring portions. The spring portions extend from the base at an angle to define a channel. Each spring portion has a free edge which engages the inner surface of the housing and forces the pressure portion into engagement with the reel. The spring portions can engage raised portions of the housing inner surface to divide the total spring force between two regions of the housing.
