DEFINITION

Classification: 400/532

Variable line spacing (e.g., platen creep):

(under subclass 531) Subject matter wherein the distance that the retaining means moves between successive print-line* rows is changed.

(1) Note. The typewriter of this subclass sometimes has a platen* moved with "platen creep", (i.e., increment of platen rotation smaller than usual line-space* increment).
