Problems solved by technology

[0020] However, conventionally, when the lens driving device and the image sensor board are coupled to each other, it is difficult to handle the flexible circuit board protruding from the lens driving device and connected to the image sensor board, which causes assembly errors of the flexible circuit board and the image sensor board and increases assembly time
[0021] In addition, when the facing portions of the lens driving device and the image sensor board adhered to each other come into contact with each other due to, for example, reliability testing, this may significantly deteriorate the performance of the camera module
[0022] In addition, due to the narrow bonding area of ​​the adhesive provided between the image sensor board and the lens driving device, the lens driving device and the image sensor board may be easily separated from each other due to external impact.

Abstract

One embodiment of a camera module comprises: a lens barrel including at least one lens; a bobbin for accommodating the lens barrel; and a fixing part disposed between the lens barrel and the bobbin soas to prevent the lens barrel from being separated from the bobbin, wherein one surface, which makes surface contact with the fixing part, of the bobbin can include a bobbin rib provided so as to protrude toward the lens barrel.

Description

technical field [0001] Embodiments relate to a lens driving device and a camera module including the lens driving device. Background technique [0002] The disclosure described in this section merely provides background information related to the implementations and does not constitute related art. [0003] Recently, IT products equipped with miniature digital cameras, such as mobile phones, smart phones, tablet computers, and laptop computers, have been actively developed. [0004] In the case of a camera module installed in a small electronic product such as a smartphone, the camera module may be frequently impacted during use, and may shake slightly due to, for example, a user's hand tremor. In view of this, there has recently been a need to develop a technology in which a hand shake compensation device is additionally provided to the camera module. [0005] In order to prevent the camera module from shaking slightly due to, for example, the user's hand shaking during i...
