Patent ID: 8902723

Claim:
A fixing structure of an optical component for fixing an optical component to a device chassis, the fixing structure comprising: a device chassis on which the optical component is mounted, the device chassis having a joint part in which a U-groove and a plurality of through-holes around the U-groove are formed; a holder holding the optical component that has an optical axis aligned to form a predetermined angle with a holder reference surface and is bonding-fixed by a resin, a first plate part and a second plate part for joint to the device chassis and a connecting part that connects the first plate part to the second plate part being formed in the holder, a plurality of joint holes being formed in the second plate part, the connecting part of the holder being fitted into the U-groove of the joint part of the device chassis; and an adhesive that is extended in a circular columnar shape and is made by inserting the connecting part of the holder into the U-groove of the joint part of the device chassis, and positioning the device chassis and the holder in such a manner that the joint holes of the second plate part are opposed to the through-holes of the device chassis, and applying a UV-curing adhesive in such a manner that the UV-curing adhesive is bonded to the first plate part of the holder and is continuous to the inside of the joint hole via the inside of the through-hole, and radiating UV light along the center of the through-hole to cure the UV-curing adhesive.
