Abstract

Boat-shaped lead-screw follower 10 is biased by coil spring 11 to twist clockwise within lead screw groove 12, thereby centering the connection shaft 13 of follower 10 within groove 12. Lead screw 19 may be used, for example, to drive a print head 14 along a writing line 15. The lead-screw follower 10 is mounted within print head carrier 16. The boat-shaped follower 10 minimizes the adverse effects of frictional wear on surfaces 17 and 18 by rotating, as required, to maintain shaft 13 centered within groove 12.
