Strip Chart Recorder Platen

This article relates to platens for strip chart recorders and more particularly to platens which are cylindrical in shape and have separate surface portions which are adapted for simultaneous use with both printheads and pens or styli.

The above figure shows an exploded view of a cylindrical platen 1 having a metallic portion 2 and a deformable portion 3. The latter element has the form of a sleeve and is adapted to fit over a shaft 4 which extends from metallic portion
2. Portion 2 and shaft 4 may be machined from aluminum or other suitable metal, such as stainless steel. Deformable portion 3 may be made of rubber having a durometer reading of 40-60. Using readings in this range, thermal printheads are basically self-aligning and less sensitive to minor misalignments. Metal portion 2 permits non-point-contact heat pens to transfer analog data to strip charts. Roller platens of the character described above may be utilized by mounting the platen directly to a recorder or by mounting the platens in a separate platen assembly.
