Description

本発明は、導光体が高精度に取り付けられており、原稿を適切に照らすことができる画像読取装置を提供することを目的とする。   An object of the present invention is to provide an image reading apparatus in which a light guide is attached with high accuracy and can properly illuminate a document.

上記目的を達成するために、本発明の画像読取装置は、受光した光を電気信号に変換する画像読取手段と、原稿からの光を前記画像読取手段に結像する結像手段とを有する光学ユニットと、前記原稿を照明する照明手段とを有し、前記照明手段は、基板と、前記基板に実装された複数の発光素子と、前記基板に固定されており、前記複数の発光素子からの光を入射する導光体と、前記光学ユニットに固定されるハウジング部材とを有し、前記導光体はボスを有し、該導光体のボスが前記ハウジング部材に当接しているとともに、前記基板と前記ハウジング部材との間には隙間が存在し、前記導光体のボスが前記ハウジング部材に当接している箇所が接着剤により固着されているとともに、前記隙間が維持されるように前記基板と前記ハウジング部材とが接着剤により固着されていることを特徴とする。   In order to achieve the above object, an image reading apparatus according to the present invention includes an image reading unit that converts received light into an electrical signal, and an image forming unit that forms an image of light from a document on the image reading unit. A lighting unit configured to illuminate the original, the lighting unit being fixed to the substrate, the plurality of light emitting elements mounted on the substrate, A light guide for entering light, and a housing member fixed to the optical unit, the light guide has a boss, and the boss of the light guide is in contact with the housing member; A gap exists between the substrate and the housing member, and a portion where the boss of the light guide is in contact with the housing member is fixed by an adhesive, and the gap is maintained. The substrate and the housing And the member is characterized in that it is fixed by an adhesive.

本発明によれば、導光体が高精度に取り付けられており、原稿を適切に照らすことができる。   According to the present invention, the light guide is attached with high accuracy, and the original can be appropriately illuminated.
