FIXED STRUCTURE OF OPTICAL COMPONENT, METHOD OF FIXING OPTICAL COMPONENT, OPTICAL PICKUP DEVICE, AND MODULE DEVICE WITH RGB THREE PRIMARY COLOR LIGHT SOURCE

摘要

The problem to be solved in the present invention is how to provide a fixing structure of an optical component capable of fixing and attaching a holder to maintain an LD or a light receiving device to a device housing by interposing a UV curable adhesive and preventing the misalignment of a sub micron order. To solve the problem, the present invention includes the device housing to mount the optical component, a holder to maintain the optical component which is attached by resins and is fixed, first and second plate parts which are formed on the holder to be attached to the device housing, and a connection part of both plate parts. A plurality of adhesion holes are formed on the second plate part. A U-shaped groove for fitting the connection part of the holder is formed on the adhesion part of the device housing. A plurality of penetration holes are formed around the U-shaped groove. A location is determined by making each adhesion hole of the second plate part face each penetration hole of the device housing by inserting the connection part of the holder into the U-shaped groove of the adhesion part of the device housing. The UV curable adhesive is continuously sprayed in the penetration hole and the adhesion hole and is adhered to the first plate part of the holder. A cylindrical adhesive is cured by radiating UV rays along the center of the penetration hole.
