Abstract: A driving mechanism is provided, including a housing, a hollow frame, a holder, and a driving assembly. The frame is fixed to the housing and has a stop surface. The holder is movably disposed in the housing for holding the optical element. The driving assembly is disposed in the housing to drive the holder and the optical element moving along the optical axis of the optical element relative to the frame. Specifically, the stop surface is parallel to the optical axis to contact the holder and restrict the holder in a limit position.

Abstract: An integrated structure of auto focus (AF) and optical image stabilizer (OIS) mechanisms includes a lens holder, a frame, magnets, suspension elements, and a driver board. The lens holder has an AF coil disposed outside thereof and is suspended in the frame. The inner edges of the sidewalls of the frame are close to but do not contact the outer edge of the AF coil. The magnets are disposed between the frame and the lens holder and correspond to the outer edge of the AF coil, for driving the lens holder back and forth along an optical axis (i.e. the Z axis). The suspension elements suspend the frame in the direction of the optical axis. The driving board has fine pattern coils each corresponding to one of the magnets, for driving the frame laterally (i.e. along the X-axis and/or Y-axis) with respect to the optical axis.

Abstract: A lens driving mechanism is provided, including a bottom plate, a housing, a movable portion, and a biasing assembly. The housing is disposed on and connected to the bottom plate. The movable portion and the biasing assembly are disposed in the housing. The movable portion has a base and a holder, wherein the holder is configured to hold an optical lens and connects to the base. The biasing assembly connects the bottom plate and the movable portion, and is configured to force the movable portion to move relative to the bottom plate. When the holder moves to a limit position relative to the base, the holder contacts the housing.

Abstract: A camera device is provided, which includes an image sensor and an optical lens arranged corresponding to the image sensor. An axis is defined on the light incident surface of the image sensor. The edge of the optical lens includes a straight segment that is parallel to the axis. Since the non-effective area of the optical lens is decreased, the camera module has a smaller size.
