Abstract

In a paper feeding system, a contact condition analysis between a rubber roller and a printing paper is needed for a stable feeding operation. Direct observation of the apparent contact area between the rubber roller and the thermal print head is also necessary for better understanding of the contact condition. However a contact microscope technique takes a lot of time to measure the real contact area. Thus another new technique is expected for faster observation of real contact area. In this paper, it was confirmed that a newly developed laser microscope with wide field of view was able to observe real contact area between the rubber plate and the glass plate. Then a distribution of real contact area of the rubber roller against the glass plate was also observed by this technique. In addition the micro-slips of the rubber roller were measured when the some torque was applied.
