摘要： A lifting and lowering mechanism for an ink ribbon and a correction tape of a typewriter includes a stepper motor which drives both a ribbon lift arm and a tape lift arm. First and second gear wheels, partially geared at predetermined portions and pivoted along the stepper motor shaft, engage with a gear wheel equipped at the ribbon lift arm and the tape lift arm respectively. The ink ribbon and the correction tape are lifted separately and selectively by changing the direction of the stepper motor rotation.

摘要： A welt forming device comprises: base fabric holding means which is able to hold a base fabric flat at all times; and welt fabric holding means for fixedly holding a welt fabric on the base fabric. Those means are moved in a sewing direction in synchronization with the vertical movement of the sewing needle of seam forming means, to form a first seam to sew the welt fabric to the base fabric. The device further comprises: first welt fabric folding means for folding one side portion of the welt fabric along the first seam over the other side portion; second welt fabric holding means for folding the other side portion of the welt fabric over the one side portion which has been folded by the first welt fabric holding means; and auxiliary moving means for moving the relative position of the base fabric holding means and the sewing needle in a direction which is across the sewing direction.
