DEFINITION

Classification: 400/630

Including aligning of sheet edge prior to typing:

(under subclass 578) Subject matter wherein significance is attributed to structure for positioning or locating a sheet of record-medium* with respect to some part of a typewriter, which structure is used before any of the character* symbols are imprinted on the sheet and is used by positioning a border of the sheet against the structure.

(1) Note. In most typewriters a sheet is inserted adjacent to the platen* and moved in a line-space* direction. The "leading" edge of the sheet is that edge which is parallel to

a print-line* (i.e., perpendicular to the line-space direction) and enters the typewriter first. The "side" edge of the sheet is that edge which is parallel to the line-space direction. The structure of this and indented subclasses ensures that either or both of the edges will be properly aligned with the print-lines so that the typed text will have a pleasing appearance on the page*.
