摘要： PROBLEM TO BE SOLVED: To provide a structure of an optical pickup device that prevents swelling of an adhesive onto a condenser lens surface. SOLUTION: The optical pickup device includes a condenser lens 16 for condensing light from a light source on an irradiation object, and a lens holder 15 for supporting the condenser lens. A plurality of notches 16A are formed in the radial-direction outer circumferential part of the condenser lens 16. The notches 16A are opened on a contact surface side between the outer circumferential part of the condenser lens 16A and the lens holder 15. Two cut surfaces of the notch 16A facing each other in a circumferential direction have a wedge shape symmetrical to each other when seen from the outer circumferential side of the condenser lens. The condenser lens 16 and the lens holder 15 are bonded together by an adhesive 20 filled into the notch parts 16A. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a coupling structure of optical parts capable of preventing the wraparound of an adhesive into the effective transmission region of the two optical parts coupled to each other via the adhesive, and an optical pickup system. SOLUTION: In a hologram element 23 disposed on a common light transmission route 22, adhesive inflow grooves 28, 29 opened in an extension direction are formed between an effective light transmission region S1 including a light transmission route 22, and adhesive application regions S2, S3 near outer edges to make the excess adhesive flow into the adhesive inflow grooves 28, 29 in the laminated state of the respective hologram elements 23, 24 until the adhesive arrives at the effective light transmission region S1. Further, the excess adhesive is made be discharged to the outside from the opening of the adhesive inflow grooves. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：提供一种光学部件的联接结构，其能够防止粘合剂经由粘合剂彼此连接的两个光学部件的有效透射区域中的环绕，以及光学拾取系统。解决方案：在设置在公共光传输路径22上的全息元件23中，在包括光传输路径22的有效光透射区域S1和粘合剂施加区域之间形成沿延伸方向打开的粘合剂流入槽28,29 S2，S3，以使多余的粘合剂以各个全息元件23,24的叠层状态流入胶粘剂流入槽28,29中，直到粘合剂到达有效透光区域S1为止。此外，多余的粘合剂从粘合剂流入槽的开口排出到外部。版权所有（C）2010，JPO＆INPIT
