用紙ガイドの摩擦抵抗を考慮した用紙挙動解析 : プリンタ給紙部における用紙ガイド形状とその改善

A highly reliable paper-feeding mechanism is necessary for printers. To achieve this, it is important to estimate the friction force and deformation of the paper. This is not easy, however, because the guide is usually bent in a "C" or "U" shape. The paper is bent by friction with the paper guide, and paper deformation is large. A simple beam model considering the friction force of the paper guide is therefore introduced to simulate paper behavior. The results of numerical simulations and experiments are shown in this paper. These results indicate that this calculation model is quite useful in predicting paper behavior and improving paper-handling machines.
