Abstract
A single stepping motor 10 driven to effect ribbon feed, ribbon lift, correction tape feed, correction tape lift is disclosed. The stepping motor 10 controls a cam 60/follower 64 pair to effect lift through a connection link 54 to a depending coupling 56 on the ribbon cartridge 22. The link 54 provides accurate positioning of the ribbon cartridge 22 without regard to the cam position and further transmits ribbon feed motion through to the depending coupling to the ribbon driver 30. Correction tape feed is effected through link 54 controlling the oscillation of the cartridges 22, 24 relative to a tape feed cam member 44.
