<P>PROBLEM TO BE SOLVED: To store and adhesively fix a plurality of plastic lenses to a lens barrel, in such a state that a direction in a vertical direction is aligned, without reversing an assembled part. <P>SOLUTION: Respective plastic lenses 4 to 7 are overlapped in order, and the conical opposing surfaces 21 to 27 of the respective plastic lenses 4 to 7 are engaged with each other, to align an optical axis S of the respective plastic lenses 4 to 7. A visible light-curable adhesive 40 is adhered to an upper surface side of an edge potion 7b of a fourth plastic lens 7, the respective plastic lenses 4 to 7 are covered by the lens barrel 2, and then, a peripheral portion of the upper surface of the edge portion 7b of a seventh plastic lens 7 is butted against a bottom edge of the lens barrel 2. In this state, a visible light is emitted from above the lens barrel 2, and the adhesive 40 is cured with the visible light which is made incident from an opening window 10 of the lens barrel 2 and passes through a first to fourth plastic lenses 4 to 7, to adhesively fix the fourth plastic lens 7 to the lens barrel 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
