一眼レフカメラ内部ミラーの跳ね返り抑制のためのダイナミックダンパーの考案

抄録

This research deals with rebound vibration behavior of movin mirror inside a SLR camera. The differences of the mirror vibration phenomena is tested by using the two-rectangular-metal-plates model, which is bonded by double-sided tape. By changing the pasting position, the mirror part functions as a damper and the rebound amount is reduced. When the frequency ratio between the mirror part and the body part was 1.0 times, the rebound amount is not reduced. On the other hand, the frequency ratio between the mirror part and the body part is 0.5 times, the rebound amount is suppressed.
