This study deals with the vibration characteristics of a SLR camera's internal mirror rebound. The mechanism of the mirror rebound phenomena is considered by using a simple rectangle metal plate models. In the experiment, the behavior of vibration during rebound of the camera mirror is observed. The mirror models are supported with rotational axis at long axis of the model. The mirrors are swung down freely from the horizontal plane and then hit with a stopper. Amount of rebound is measured by a laser displacement meter. The rebound amount depends on the stopper position. The Vibration behavior after the collision varies by stopper position. The Vibration after the collision depends on the deformation while in contact with the stopper at the time of collision.
