Abstract

The present disclosure relates to a camera module, the camera module including a circuit board, an image sensor disposed on an upper surface of the circuit board, a current carrying part electrically connecting the image sensor and the circuit board, and a base disposed on the upper surface of the circuit board, wherein the base is not overlapped with the image sensor and the current carrying part in a direction of an optical axis.

First claim

What is claimed is:

1 . A camera module, the camera module comprising:
a circuit board; an image sensor disposed on an upper surface of the circuit board; a current carrying part electrically connecting the image sensor and the circuit board; and a base disposed on the upper surface of the circuit board, wherein the base is not overlapped with the image sensor and the current carrying part in a direction of an optical axis.

2 . The camera module of claim 1 , further comprising:
a lens module arranged at an upper side of the image sensor; and a filter interposed between the lens module and the image sensor, wherein the base includes a first support unit supporting a part of a bottom surface of the filter, a second support unit disposed opposite to a lateral surface of the filter, and a third support unit arranged at an upper surface of the circuit board to connect the first and second support units.

3 . The camera module of claim 2 , wherein a bottom surface of the first support unit contacts the upper surface of the circuit board.

4 . The camera module of claim 2 , wherein a width of the first support unit in a direction perpendicular to a direction of an optical axis (hereinafter referred to as ‘optical axis direction) is broadened toward an upper side from a lower end of the first support unit.

5 . The camera module of claim 2 , wherein an upper surface of the first support unit and an inner lateral surface of the first support unit form an acute angle.

6 . The camera module of claim 2 , wherein a height of the second support unit in the optical axis direction corresponds to a height of the filter in the optical axis direction.

7 . The camera module of claim 2 , wherein an upper surface of the filter and an upper surface of the second support unit are arranged on one plane.

8 . The camera module of claim 2 , wherein the filter is spaced apart from the image sensor and the current carrying part.

9 . The camera module of claim 2 , wherein the filter is an absorption filter or an IR reflection filter.

10 . The camera module of claim 1 , wherein the current carrying part includes a wire coupled to an upper surface of the image sensor and an upper surface of the circuit board.

11 . The camera module of claim 1 , wherein the wire is arranged at an external side of the image sensor.

12 . The camera module of claim 1 , further comprising:
a cover member arranged at an upper side of the base; a bobbin arranged at an inner side of the cover member; a first coil arranged at the bobbin; a magnet interposed between the cover member and the bobbin to be opposite to the first coil; and a second coil arranged at the base to be opposite to the magnet.

13 . The camera module of claim 1 , further comprising a circuit element unit arranged at an upper surface of the circuit board and arranged at an outside of the image sensor, and
wherein the base is formed with an element accommodation part accommodating at least a part of the circuit element unit.

14 . The camera module of claim 13 , wherein the element accommodation part passes through the base to an optical axis direction.

15 . The camera module of claim 13 , wherein the base is prevented from being overlapped with the circuit element unit in an optical axis direction.

16 . The camera module of claim 13 , wherein the element accommodation part includes a first accommodation part arranged at one side of the image sensor and a second accommodation part arranged at the other side of the image sensor.

17 . The camera module of claim 13 , wherein the circuit element unit includes first to fourth circuit elements, each element mutually spaced apart from the other element,
wherein the element accommodation part includes a first accommodation part accommodating the first and second circuit elements, and a second accommodation part accommodating the third and fourth circuit elements, and wherein the first accommodation part and the second accommodation part are spaced apart from each other by the base.

18 . The camera module of claim 13 , further comprising:
a cover member arranged at an upper side of the base; a lens module arranged at an upper side of the image sensor; and a filter interposed between the lens module and the image sensor, wherein the base includes a filter support part supporting the filter, and a cover member support part supporting the cover member, and wherein the element accommodation part is arranged between the filter support part and the cover member support part.

19 . An optical apparatus, the optical apparatus comprising:
a main body, a camera module arranged at the main body to photograph an image of a subject, and a display part arranged at one surface of the main body to output the image photographed by the camera module, wherein the camera module comprises: a circuit board; an image sensor disposed on an upper surface of the circuit board; a current carrying part electrically connecting the image sensor and the circuit board; and a base disposed at the upper surface of the circuit board, wherein the base is not overlapped with the image sensor and the current carrying part a direction of an optical axis.

20 . The optical apparatus of claim 19 , further comprising a circuit element unit arranged at an upper surface of the circuit board, and arranged at an outside of the image sensor,
wherein the base is formed with an element accommodation part accommodating at least a part of the circuit element unit.
