.~ Key-board having multiple-character, multiple-movement keys
DEFINITION
Classification: 400/485
Key-board having multiple-character, multiple-movement keys:
(under subclass 472) Subject matter wherein significance is attributed to a key-board* having key* elements that are movable in a plurality of directions as pressed by a typist, each of which directional movements of a key element effecting the imprinting of a different character* symbol on the record-medium*.
(1) Note. In most typewriters a typist presses an individual character key to imprint either the upper-case* or the lower-case* form of a letter, and certain of the character keys are usable to imprint either a number or a
particular symbol. The choice of symbols imprinted by pressing a particular key is limited to one of two symbols in such typewriters. In a typewriter of this subclass, a key element is pressed and moved in the plane of its face, and the direction of its movement will effect typing of a different character.
