When we take pictures with continuous shots with single lens reflex camera, the inner mirror must repeats to go down and up with very high-speed. In this operation, the mirror hits to a stopper and rebound instantaneously. We investigate the rebound characteristics of the mirror model with free fall testing. Rebound angle of the model is varying by the stopper position. In the experiments, we find the stopper position which has lower amount of rebound angle. And the experimental modal analysis is carried out for the mirror and stopper model. It is found that the modal dumping ratio is correlate with the amount of rebound angle.
