Optical assembly driving mechanism

The utility model provides an optical assembly driving mechanism. The optical assembly driving mechanism comprises a movable part, a fixed part, a driving assembly, at least one light emitter and at least one light receiver. The driving assembly is used for driving the movable part to move relative to the fixed part. The light emitter provides a light ray to an object, and the light receiver receives the light ray after the light ray hits the object and is reflected. 本实用新型提供一种光学组件驱动机构，包括一活动部、一固定部、一驱动组件、至少一光发射器、以及至少一光接收器。驱动组件用以驱动活动部相对于固定部运动。光发射器提供一光线射向一物体，且在光线击中物体被反射后，光接收器接收前述光线。
