Abstract
A recording apparatus in which the cantilevered arm supporting a recording device has a smoothly curved surface adjacent the flexure spring joining the arm to a carriage whereby a rolling pivot is provided such that the bending stress on the flexure spring is minimized and is constant and independent of the degree that the cantilevered arm is raised. An end of the cantilevered arm is held against the carriage by a spring, one end of which is coupled to a translation mechanism which permits the recording device load force to be adjusted.
