Abstract
This study deals with coefficient of restitution of camera mirror models. Coefficient of restitution differs depending on collision position. Because mirror models are made of thin sheet metal, it is expected that the vibration mode of it influences the coefficient of restitution. The objective of this study is to find the position of collision on the model with the minimum coefficient of restitution, and to find the relationship between the vibration mode of the model and the coefficient of restitution. As a result, the position of minimum coefficient of restitution is able to forecast by theoretical modal analysis. The next problem is to forecast the tendency of coefficient of restitution.
