Abstract

PURPOSE: To provide an open-shut mechanism for the programmed shutter wherein at the shutting operation of an open-shut a actuating lever, two springs the force of which increases in accordance with a decreasing aperture of the control opening are used as a force while the brightness varies as the reciprocating momentum and speed so as to enable a high speed or high LV value control.
