A camera module includes a filter, a supporting base, a metal sheet, and a fixing member. The supporting base includes a first through hole, a first surface, and a second surface. A receiving groove is recessed from the second surface toward the first surface, an inner wall defining the receiving groove includes a bottom surface. The first through hole penetrates the first surface and the bottom surface. The metal sheet is received in the receiving groove and includes a second through hole. A central axis of the second through hole is collinear with a central axis of the first through hole. The metal sheet further includes a supporting platform exposed from the first through hole, the filter is mounted on the supporting platform and received in the first through hole. The fixing member is arranged on the supporting base to fix the metal sheet to the supporting base.

Various embodiments include perimeter sheet spring suspension arrangements for cameras. A perimeter sheet spring suspension arrangement may be used to suspend a moveable platform of the camera from a base structure of the camera, and allow a lens group of the camera to move laterally. According to some embodiments, the perimeter sheet spring suspension arrangement may include one or more tabs that may be used as bumpers that cushion lateral movement of the moveable platform.

A tray feeding box includes a box body; a cover, arranged at a first end of the box body; and a bottom board, arranged at a second end of the box body away from the cover. The cover includes at least one first cover arranged at the first end of the box body. The at least one first cover is defined with a first opening. The box body is defined with a take-out gap communicated with the first opening.

The present embodiment relates to a dual camera module comprising a first camera module and a second camera module, wherein: a first magnet unit of the first camera module includes a first magnet and a second magnet, both disposed opposite to each other on a side surface of a first housing; a second magnet unit of the second camera module includes a third to a sixth magnet arranged on four respective corners of a second housing; a third magnet unit is disposed on a side surface of the first housing facing the second housing; the third magnet unit is disposed between the first magnet and the second magnet; and the third magnet unit is smaller than the first magnet and is disposed on a virtual line connecting an optical axis of the first camera module and an optical axis of the second camera module.

The driving unit includes: a first contact portion and a second contact portion that move relatively to each other while making contact with each other during driving; in which the second contact portion includes a coating layer at a contact face with the first contact portion, and the first contact portion and the second contact portion generate heat along with relative movement to vaporize a worn-away part of the coating layer.

The proposed invention relates to a camera module with an optical image stabilization function. A flexible printed circuit board (FPCB) electrically connected to an image sensor is implemented to serve as an electrical path and at the same time, serve to provide an elastic restoring force in directions of a plurality of axes, thereby further miniaturizing and lightening the camera module.

A lens barrel having one end and the other end includes: a first frame that is movable and holds optical members; a second frame that is arranged to be relatively movable toward the other end with respect to the first frame, and holds optical members; and a third frame that is mounted on the first frame so as to be movable, and holds an optical member. The first frame includes a first stopper portion that comes into contact with the third frame to limit movement toward the one end. The first frame includes a second stopper portion that comes into contact with, when the first frame is most distant from the second frame, the third frame to limit movement toward the other end. The second frame includes a third stopper portion that has a contact surface located close to the one end with respect to the second stopper portion, and that comes into contact with, when the second frame is located within a range on the optical axis where the third frame is movable, the third frame to limit movement toward the other end.

The tri-axis close-loop feedback controlling module for electromagnetic lens driving device comprises a 6-pin Hall element. Two pins of the Hall element are coupled to an auto-focus module for providing a current to drive the auto-focus module to conduct auto-focusing operations along the Z-axis; while other four pins of the Hall element are coupled to a control unit. The control unit detects the X-Y axial positions of the auto-focus module relative to an OIS module and generates a control signal which is then sent to the Han element. Therefore, the Hall element not only can provide its own feedback controlling function according to the Z-axial position of lens, but also can drive the auto-focus module based on the control signal corresponding to the X-Y axial positions of the auto-focus module, so as to achieve the goal of tri-axis close-loop feedback controlling for the electromagnetic lens driving device.

A method of manufacturing a camera module that is low profile and that can achieve superior resolving power, a camera module, and an imaging device are provided. A positioning step of positioning an object-side group optical unit (12a) along an optical axis direction with the use of a jig (40) such that the object-side group optical unit (12a) is located so as not to be in contact with an image-plane-side group lens (32a) and a fixing step of fixing the object-side group optical unit (12a) to a lens holder (20) are included.

A lens driving mechanism is provided, including a bottom plate, a housing, connected to the bottom plate, a movable portion movably received between the housing and the bottom plate, and a biasing assembly connecting the bottom plate to the base of the movable portion. The movable portion includes a frame, a holder, and a base, wherein the holder is received in the frame and configured to sustain the optical lens, and the base is connected to the frame and the holder. The biasing assembly connects the bottom plate to the base of the movable portion, wherein when viewed in a direction perpendicular to the optical axis, the base and the biasing assembly partially overlap.
