Classification: 400/488
Key-board including row of keys having different heights:
(under subclass 472) Subject matter wherein significance is attributed to the positioning of the key* elements of a key-board* in accordance with the distances from the topmost surface of each key element to a common base.
(1) Note. In most typewriters, the key elements are arranged in a plurality of rows, each row extending transversely across the front of the key-board and one row of keys higher or lower than another. This arrangement conforms to the design and manufacturing requirements of most of the
