ABSTRACT:
A drive assembly for reels of microfilm provided in a cartridge and placed in a cartridge receiving channel in a direction normal to the axis of the reel supporting the coil of microfilm and usuable with cartridges having differently designed reels comprises a main drive shaft which can be coupled direct to the reel with a backup wheel or coupled to a drive head that is connected in driving engagement with the reel. Automatic locking means and spring biased drive parts afford a drive that is adaptable to the cartridge reel. Releasable drive means withdraw the drive shaft and drive head from the cartridge receiving channel.
