Title: Lens shutter driving mechanism concurrently available for lens driving mechanism
Inventor: NAKAMORI MASAO
IPC: G02B7/28
Filed: 1991-03-27
Abstract: PURPOSE:To simplify members in mechanism in which a single step motor is used as driving sources for both lens driving mechanism and a shutter driving mechanism. CONSTITUTION:When a cam ring moves forward as a motor rotates in normal direction, a lens driving ring passively. After engagement of the lens driving ring, and in the process of backward movement of a cam ring, a cam follower 6a falls down to a cam edge, an opening/closing level 6 operates to open, then the cam edge makes the opening/closing level 6 to close. When the cam ring moves forward, the cam edge passes the position of the follower, but at that time, because the edge of the lens driving ring stops the cam follower 6a, the opening/closing level 6 cannot operate. Accordingly, any intermediate member such as an uni-directional clutch is no more required for restricting the operation of the opening/closing level 6 during operation of lens projection, so that the mechanism can be simplified.
