Abstract
A cartridge 12 for correction tape 22 is disclosed which utilizes a cam follower 40 operated pawl 50/ratchet 52 for feeding of the tape 22, where the pawl 50 is operated as a result of the movement of a cam follower 40 against a cam 40 on the support frame 10. As the cartridge 12 oscillates, the pawl 50 is displaced to increment the ratchet 52 to effect feed.
