发明名称 Film winding and lens control mechanism for automatically focusing camera
摘要 In an automatically focusing camera, the lens is driven to infinity during film winding and the film winding spool is blocked when film winding is completed. Upon shutter release actuation of the camera, film winding is unblocked when the automatic focusing circuit energizes a first magnet and lens rotation is blocked at the focused position when the automatic focusing circuit energizes a second magnet. A single control member operates to effect blocking of the film winding mechanism and to drive the lens to infinity when rotated in one direction, and to unblock the film winding mechanism when rotated in the opposite direction.
