Optical pickup device and laser welding structure of optical components |
摘要 |
To provide a reliable optical pickup device, a pickup case and an optical component including a lens are fixed by laser welding to increase the welding strength and reduce the positional displacement due to environmental changes. In a laser welded portion between a pickup case and an optical component including a lens, the optical component is provided with a joint portion having a convex protrusion at a portion to be joined to the pickup case. Laser beam irradiation is performed extending longer than the protrusion to form a thick welded portion at an end of the protrusion, in order to increase welding strength between the optical component and the pickup case. |
