LENS BARRIER DRIVING MECHANISM FOR CAMERA

摘要

PROBLEM TO BE SOLVED: To make a camera light in weight and compact by eliminating a driving mechanism dedicated to an inner barrier. SOLUTION: In this lens barrier driving mechanism, a finder cam 26 moving the moving lens holding frame of a finder 20 back and forth in an optical axis direction and the inner barrier 10 are coupled through a pin 42 so that motive power can be transmitted, and the inner barrier 10 is driven to be opened/closed by the driving force of the finder cam 26. Thus, the driving mechanism dedicated to the inner barrier 10 is eliminated, so that the camera is made light in weight and compact.
