<p>PURPOSE:To prevent the damage accompanied with drop or the like by storing a light radiating means and a condenser lens without sticking them to a main body case. CONSTITUTION:An arm 37 extending to the vicinity of a light radiation window 1b on the side opposite to a grip part is provided with floating state from the main body cases 11 and 13. An LED substrate 15 and a condenser lens 17 are held on the arm 37 of a body, which is made of ABS resin, in such positional relations by a groove 41 that they are a prescribed length apart from each other. By the action of stopper edges 15b and 17b, they are held in the completely floating state from the upper case 13, and they are abutted on the lower case 11 in such degree that they are free from much play. Thus, they are free fm distortion to keep their original positional relations even if the vicinity of the radiation window 1b is distorted by the impact due to dropping or the like. Further, the LED substrate and the condenser lens are not broken by the distortion.</p> |
