Embodiment

To combine accompanying drawing that the embodiment of the invention is done further explain below.

See also Fig. 1, the portable electron device 100 that first embodiment of the invention provides comprises an electronics 10 and a camera module 30 of being located on the electronics 10.

Please consult Fig. 2 and Fig. 3 in the lump, camera module 30 comprises that a microscope base 40, one contain the lens barrel 50 of eyeglass (figure does not show), one and be located at circuit board 60 on the electronics 10, one and be located at image sensor 70 on the circuit board 60, and electronic component 80 of being located on the circuit board 60.

Microscope base 40 has the hollow body portion 401 and the hollow base 403 that links to each other with main part 401 that are used to accommodate lens barrel 50.

Base 403 links to each other with main part 401, and it has a top board 4031, and bottom 4033 relative with top board 4031, reaches a host cavity 4035 that runs through top board 4031 and bottom 4033 and be connected with main part 401.Top board 4031 is used to carry main part 401.Host cavity 4035 is used to accommodate image sensor 70.In the present embodiment, base 403 is a square structure.Certainly, base 403 also can be other structures such as circular configuration, triangular prism shaped structure, pentagonal prism shape structure.

Bottom 4033 forms at least two reference columns 4037 towards the edge on the surface of circuit board 60.Preferably, in the present embodiment, the number of reference column 4037 is three, and is distributed in three corners of the bottom 4033 that is square.Certainly, the number of reference column 4037 also can be two, four or more a plurality of.

Each reference column 4037 has a locating surface 4039.In the present embodiment, the cross section of each reference column 4037 is fan-shaped, and locating surface 4039 is curved.

Circuit board 60 has side 605, and at least two location divisions 607 of being located at side 605 that lower surface that a upper surface relative with bottom 4,033 601, one and upper surface 601 deviate from mutually 603, are connected upper surface 601 and lower surface 603.

The use that matches with at least two reference columns 4037 of at least two location divisions 607 is with

circuit board

60 and 4033 location, bottom.Match with a locating surface 4039

circuit board

60 and 4033 location, bottom in each location division 607.In the present embodiment, each location division 607 is arc groove, and the opening of each location division 607 all deviates from the center of circuit board 60.
