Embodiment Construction

[0042] Hereinafter, some exemplary embodiments according to the present invention will be described in detail with reference to the accompanying exemplary views. When assigning reference numerals to each element in the drawings, the same reference numerals will be given to the same or similar elements even if the elements are shown in different drawings. In addition, when it is determined that a detailed description on a known function or structure related to the present invention may evade the gist of the present invention, such detailed description will be omitted.

[0043] Also, terms such as “first,” “second,” “A,” “B,” “(a),” and “(b)” may be used when describing elements of exemplary embodiments of the present invention. However, these terms are only used to distinguish a specific element from another element, and thus, the nature, order or sequence of related elements should not be limited by these terms. It should be understood that when an element is referred to as b...

Abstract

The present invention relates to a camera module comprising: a printed circuit board having an image sensor mounted thereon; a holder member provided on the printed circuit board and having a lens barrel provided therein; an optical module arranged on the upper side of the holder member and performing an auto-focusing function and / or an image stabilization function; and an electric current applying unit for electrically connecting the printed circuit board and the optical module, wherein the electric current applying unit comprises: first and second conductive members connected to the printed circuit board; and first and second plate members which are arranged on the upper side of the holder member and are electrically connected to each of the first and second conductive members, and which are electrically connected through the optical module. Through the present invention, a separate circuit board for applying a power source to an optical module is not required, and thus, it is possible to lower the height of the camera module as much as the thickness of a circuit board.

Description

technical field [0001] Exemplary embodiments of the present invention relate to a camera module and an optical device. Background technique [0002] Conventional technologies such as VCM (Voice Coil Motor) used in general camera modules are difficult to apply to mini cameras and low power consumption camera modules. Therefore, related research has been actively conducted. [0003] Recently, camera modules capable of performing autofocus operations using actuators have been developed, enabling miniature cameras, low power consumption, and high-efficiency camera modules to prove their value. In order to drive the actuator, it is necessary to electrically connect the AF (auto focus) terminal at the two electrodes and the PCB AF (auto focus) pad to control the actuator. [0004] In particular, when a microactuator is used for miniaturization of a camera module, a complicated process of connecting electrodes as described above is required. Contents of the invention [0005] ...
