Abstract | PROBLEM TO BE SOLVED: To provide an optical module that allows fitting to be easily implemented in the optical module made up of two optical blocks requiring the high-precision fitting.SOLUTION: Positioning of optical blocks 20 and 40 is implemented step by step. Positioning means at a first step is configured by a visually visible shape, and positioning means at a second step is composed of a spring piece 41 having an abutting slope 44, a crest 35, and other crest, in which the spring piece 41 is formed in the optical block 40 so that the abutting slope 44 is located at a corner part of the optical block 40, two abutting slopes 44 on one end side in a long-side direction form a mirror image, the abutting slope 44 on other end side therein is located flush with the abutting slope 44 on an extension in the long-side direction, and each abutting slope 44 abuts on the crest 35 of the optical block 20 and other crest thereof to thereby implement positioning. Positioning means at a third step is composed of a concavity part 31 formed in one of the optical blocks 20 and 40, a guide slope 33, and a convexity part to be formed in other thereof. The convexity part is fitted into the concavity part 31.
【課題】高精度な嵌合を必要とする2つの光学ブロックからなる光モジュールにおいて、嵌合を容易に行えるようにした光モジュールを提供する。【解決手段】光学ブロック20,40の位置決めは段階的に行われる。第1段階の位置決め手段は目視可能な形状とされる。第2段階の位置決め手段は突き当て斜面44を有するばね片41と稜35,他の稜とよりなり、光学ブロック40の角部に突き当て斜面44が位置するようにばね片41が光学ブロック40に形成され、長手方向一端側の2つの突き当て斜面44は鏡像をなし、他端側の突き当て斜面44は長手方向延長上の突き当て斜面44と同一平面上に位置され、各突き当て斜面44が光学ブロック20の稜35,他の稜に突き当たることで位置決めされる。第3段階の位置決め手段は光学ブロック20,40の一方に形成された凹部31、案内斜面33と他方に形成された凸部とよりなる。凸部は凹部31に嵌合される。【選択図】図2 |
