DEFINITION

Classification: 400/600.1

With platen repositioned for sheet insertion:

(under subclass 600) Subject matter wherein the platen* of the typewriter is movable to a position at which it enables movement of the record-medium* sheet into contact with the platen.

(1) Note. In this subclass the platen together with a feed-roller* effectively form a "gate" in the feed throat that prevents insertion of the record-medium when the platen and feed-roller are engaged. In this condition the leading edge of the record-medium is stopped at the platen. The repositioning of the platen away from the feed-roller effectively opens the gate so that the record-medium can be fully inserted into the throat, usually until the leading edge of the record-medium engages a stop. The throat is then closed by moving the platen back into engagement with the feed-roller, the record-medium being located therebetween. At this time the record medium is properly located relative to the intended print-line* and may be moved in line-space* direction by rotation of the platen and the feed-roller.
