## Abstract

An imaging device includes an auto-focusing actuator, an image sensor, and a transparent dust-proofing member. The auto-focusing actuator includes a housing. The housing includes a top surface and an opposite bottom surface, and defines a through hole extending from the top surface to the bottom surface. A number of positioning rods extend from the top surface and cooperatively define a fixing space. The image sensor is mounted on the bottom surface of the housing and aligned with the through hole. The transparent dust-proofing member is mounted in the fixing space and seals the through hole.

## Claims

### Claim 1

An imaging device, comprising:
an auto-focusing actuator comprising a housing, the housing comprising a top surface and an opposite bottom surface, the housing defining a through hole extending from the top surface to the bottom surface, the housing comprising a plurality of positioning rods extending from the top surface, the positioning rods cooperatively defining a fixing space therebetween, the housing defining a number of recesses in its sidewalls, the recesses extending through the top surface, and each of the recesses positioned close to a respective one of the positioning rods;
an image sensor mounted on the bottom surface of the housing and aligned with the through hole; and
a transparent dust-proofing member mounted in the fixing space and sealing the through hole, the positioning rods contacting the transparent dust-proofing member.
