Description

光学部品収容体Optical component container
　本発明は、光学部品を固定して収容する光学部品収容体に関するものである。 The present invention relates to an optical component housing for fixing and housing an optical component.
　電気機器等には、光源からの光の光路を形成するレンズ等の光学部品が搭載されることがある。
　特許文献１には、パネルの開口部に集光レンズを挿入して固定する光学装置が開示されている。この光学装置では、パネルの開口部付近に突設部を設け、この突設部の径方向に突出した突出部に、集光レンズの外周に形成された溝部を嵌め込んで固定する。 An electrical device or the like may be mounted with an optical component such as a lens that forms an optical path of light from a light source.
Patent Document 1 discloses an optical device that inserts and fixes a condensing lens into an opening of a panel.

　しかしながら、レンズ、導光部品等の光学部品を収容する光学部品収容体の場合、有効な光路の断面積を小さくするような溝加工を外周面にすると光学特性が劣化してしまうという問題がある。特に画像に係る光を通過する光学部品の場合は、このよう溝加工はできない。一方、この場合に、有効な光路の断面積を確保しようとすると全体的に断面積を大きくする必要があり、収容体が大型化してしまうという問題がある。 However, in the case of an optical component container that accommodates an optical component such as a lens or a light guide component, there is a problem in that optical characteristics deteriorate if an outer peripheral surface is formed with a groove that reduces the cross-sectional area of an effective optical path. . In particular, in the case of an optical component that transmits light according to an image, such groove processing cannot be performed. On the other hand, in this case, it is necessary to increase the overall cross-sectional area in order to secure an effective cross-sectional area of the optical path, and there is a problem that the container is increased in size.
　また、光学部品収容体内に光学部品を挿入して組み立てる場合に、光学部品の外面が光学部品収容体の内面と擦れて傷が付き、光学部品の光学特性が劣化してしまうという問題がある。 Further, when an optical component is inserted and assembled in the optical component housing body, there is a problem that the outer surface of the optical component is rubbed and scratched with the inner surface of the optical component housing body, and the optical characteristics of the optical component are deteriorated.
　本発明はかかる事情に鑑みてなされたものであり、その目的は、光学特性を低下させることなく光学部品を安定して保持して収容可能な光学部品収容体を提供することにある。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide an optical component container that can stably hold and accommodate an optical component without deteriorating optical characteristics.
