A SHUTTER DEVICE FOR CAMERA DIAPHARAGM

摘要

PURPOSE: A shutter device for a camera aperture is provided to be miniaturized by arranging the elements of a piezoelectric motor arranged in an optical axis direction. CONSTITUTION: A shutter device for a camera aperture comprises a housing(250), a piezoelectric motor(200), an arm lever and a shutter blade. The housing has an open hole for opening a lens. A rotating member(223) revolves by the flexural deformation of a piezoelectric element(212). The piezoelectric motor is installed in the housing. The shutter blade is connected to the arm lever and opens and closes the open hole.
