Zusammenfassung: | Disclosed is a mechanism so arranged that a relatively weak power source can be employed to effect error ribbon elevation and incremental feed. A bridge which is pivotably mounted on a frame carries a rotatably mounted ratchet and a pivotably mounted pawl which, when the bridge is rotated by a magnet to elevate the bridge, is caused to react with a frame part and pivot relative to and to drive the ratchet to feed ribbon. |
