Abstract
The objective of this research is to investigate the vibration characteristic of the blade of a camera shutter unit. To clarify the vibration characteristic of the shutter blade is need to improve the sound quality and the performance of the shutter unit. The shutter blade is a thin plate part, which is combined four different shape narrow plates and two different length support arms. The forced vibration testing method on different component parts of shutter blade carries out measurements. Consequently, the vibration characteristic of the front blades and the rear blades doesn't change so much. The peak frequencies are almost same between two vibrating conditions that is the horizontal and vertical direction vibration condition. In only the vertical vibration condition, twisting vibration occurs in the constructed shutter blades.
