ABSTRACT:
A cartridge or cassette for light and pressure sensitive web-type media material includes a generally rectangular housing board received between a pair of identical housing ends, to retain a spool of such media material therein. The housing is formed with an exit opening in a front wall defined by an inwardly-extending flap parallel to the top forming a light-trap passage. Media material from the spool is guided through the light-trap passage with the outer pressure sensitive surface in non-contacting relation to the housing. The spool is formed with a central core which has an outer cylindrical surface free of discontinuities or irregularities. A pair of end flanges are received on the core having radial surfaces in close relation to the convolutions of the web. The housing ends are formed with annular inwardly-extending rings which terminate in close running relation to the adjacent outside surface of a spool end flange to support the media material and to prevent telescoping in the event the cartridge or cassette is mishandled or dropped.
