Benefits of technology

The present technology allows for capturing any particles caused during machining processes without being scattered back into other areas around them. It achieves this by fixing terminals with respectable position within holes formed at the top surface of the housing while allowing light rays passing through. This reduces the overall thickness of the apparatus'beamformers and improves image quality. Additionally, there has been developed a stable mount system where the covers used have raised parts attached to their edges, preventing separation when subjected to forces such as gravity. Overall, these technical improvements improve performance and functionality of the equipment involved in manufacture.

Problems solved by technology

This patented describes different technical features for improving the performance characteristics (performance) of cameras used in electronic devices such as smartphones that use this technology.

first embodiment

[0011]The first embodiment is intended to provide a lens driving device including a bobbin having a structure for capturing foreign matters.

[0012]It is also intended to provide a lens driving device having a structure in which captured foreign matters will not be re-scattered again.

second embodiment

[0013]The second embodiment is intended to provide a lens driving device including a structure in which deformation of a terminal is minimized.

[0014]Also, it is intended to provide a camera module including the lens driving device.

third embodiment

[0015]The third embodiment is intended to provide a lens driving device capable of performing an autofocus function and, at the same time, reducing the bezel size of the optical device by shifting the optical axis of the lens module from the center, a camera module including the lens driving device, and an optical device including the camera module.
