ABSTRACT:
A microfilm cartridge assembly includes a hollow housing in which a reel is mounted. A bearing surface results from the end of a boss on the reel making contact with a circular seat around a boss on one of the walls of the housing. The housing boss is inserted into the reel boss to provide a second bearing surface between the telescopically arranged bosses.
