Abstract
A chart recorder has all of its components mounted in a housing formed of a self-lubricating plastic material. The unit employs a single drive roller which is driven through a speed-reducing gear train by a low-torque motor and belt drive, which produces minimal noise. A special tilt plate is mounted behind the drive roller. The recorder has a swing-down front door which is movable between an open paper-roll-loading position, an intermediate paper-feed position and a closed operating position. When the door is in its paper-feed position, paper drawn from the roll can be fed manually between the roller and the tilt plate so that the recorder can be threaded up without power. When the door is closed, it resiliently biases the tilt plate against the paper trained around the drive roller so that, when the drive train is energized, the paper is advanced promptly and smoothly. A simple wire bail and cam surface locks the door in its intermediate and closed positions while simultaneously raising the recorder stylus.
