Abstract
A mounting arrangement is provided for supporting an idler roller which is adapted to backup a constant speed drive capstan in a multipurpose photographic film cassette having a sound capability. The roller support includes a C-shaped bracket having an intermediate leg and upper and lower legs which extend respectively above and below the roller and which are provided with openings to receive and support a mounting pin which extends through a central opening in the roller. The lower leg is attached to a sidewall of the housing and the upper leg is provided with an extension which is adapted to engage a structural portion of the cassette in a manner to resist the force imparted to the upper end of the idler roller mounting pin by the drive capstan.
