Abstract: A small camera module is simply assembled in a short time, while reducing displacement of a camera relative to the first and second frames. Specifically, the camera module is assembled by bending a pair of clips to engage engaging portions of the clips with engaging recesses of the first and second frames to fix the first frame, camera holders, and the second frame, with the first and second frames located at both sides of each camera holder with a housing recess facing outward, and using resilient force of each of the clips to press the camera with a projection of the clip.

Abstract: An electrode inspection apparatus for spot welding is provided for precisely measuring diameters of a tip of an electrode without reducing availability ratio in a production line, and is particularly useful when inspecting a weld gun having electrodes with a narrow distance therebetween. A CCD camera 91 for imaging the tip of the electrode held to the weld gun is disposed in an inspection apparatus body 6. The inspection apparatus body 6 includes a measuring reference unit 7 in which a fixing hole 72a for fixing the tip of the electrode is formed, and a mirror 8 obliquely arranged with respect to the electrode so as to be distant from the fixing hole 72a at a position opposite to the electrode with respect to the measuring reference unit 7. The CCD camera 91 is disposed in a side of the mirror 8 with a distance therebetween for imaging the tip of the electrode from a direct front thereof reflected on the mirror 8 by reflection.
