DEFINITION

Classification: 400/211

Including mechanism for shifting ribbon laterally at print-point:

(under subclass 191) Subject matter wherein the

transfer-medium* is a ribbon and provision is made for moving the ribbon in a direction transverse to its elongated dimension, such movement occurring in an area of the typewriter adjacent to the print-point*.

(1) Note. In this subclass (211) the transverse movement occurs by reason of the entire ribbon and the spool(s) on which the ribbon is wound or mounted being moved in the transverse direction.
