PROBLEM TO BE SOLVED: To improve the relative positional accuracy of a photodetector to other parts such as holder. SOLUTION: The image of one corner (part to be recognized) of a seal frame 3 fixed to a printed board is recognized to detect the position of this frame 3, specified mounting position inside the frame 3 is determined by referring to the detected position, and a photodetector 3 is mounted there. A sealant 4 is poured and curved in the frame 3 to seal the photodetector 2. For mounting it on an other member such as a holder, pins of the member are inserted into a secured to mounting means 6a, 6b formed on the frame 3. The frame 3 used to mount the photodetector 2 and fix it to other members, and hence the detector 2 is fixed to other member at a high relative positional accuracy. |
