ABSTRACT:
A strip chart recorder having cantilevered spring arms integrally molded with its rigid chassis. One set of spring arms maintains pressure on a paper drive nip, another set permits resilient deflection of a rod to latch a paper supporting door, and a third set resiliently retains the paper supply roll. Improved drive is obtained by movable mounting of the drive roll in a special relationship that causes it to react to resistance of the paper by tightening the drive nip pressure.
