Abstract
A belt-driven tape cartridge has tape spools rotatably mounted in the cartridge, and a belt drive assembly for driving the tape back and forth between the spools. The drive assembly includes three roller supporting pins, a driving roller rotatably mounted on one of the pins and a pair of guide rollers rotatably mounted on the other pins, and an endless drive belt extending around the rollers to contact tape on each spool. The cartridge has an opening for entry of a drive roller to engage and drive the belt driving roller so as to move the drive belt and drive tape back and forth between the spools. The drive roller mounting pin has a recess extending over at least a portion of the pin facing the drive opening for reducing the bearing surface area between the pin and driving roller so as to reduce the tangential drive force needed to rotate the driving roller.
