Abstract
A variable cam profile selection system is disclosed having cams controlling both the tilt and the rotate motion of the single element typewriter. The tilt cam and rotate cam are mounted so that they may be moved with respect to their support to vary the cam rise. The rise of the cam is controlled by interposers under the influence of the keyboard to select or define the amount of movement of the cam member, thereby defining the cam rise. The single cam member for each movement may be positioned in any one of a plurality of positions and, by so doing, correspondingly effect the movement of the cam follower as the cam is rotated about an axis.
