PROBLEM TO BE SOLVED: To make illumination light emitted by a light source incident to a light guide efficiently.SOLUTION: An endoscope apparatus processor is provided with a light source part 30 housing a light source unit 40 in a case 42, and the light source unit 40 is fitted to a movable plate 50. By a drive mechanism provided with screw parts 60A to 60C, motors 80A to 80C or the like screwed with the movable plate 50 at three parts, it is possible to adjust directions a movable surface 50S of the movable plate 50 faces. While changing directions of the movable plate 50 by moving one screw part with an automatic optical axis adjusting part, it is determined whether or not there is a change in quantity of light of two line sensors that are not positioned on the diagonal line, and the movable plate 50 is positioned at the position where there is no change in quantity of light.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2019,JPO&INPIT【課題】光源から放射される照明光を、効率よくライトガイドへ入射させる。【解決手段】内視鏡装置のプロセッサは、光源ユニット40をケース42に収容させた光源部30を備え、光源ユニット40は可動板50に取り付けられている。そして、可動板50と3箇所で螺合するネジ部60A~60Cおよびモータ80A~80Cなどを備える駆動機構によって、可動板50の可動面50Sの向く方向を調整することができる。そして、自動光軸調整部によって1つのネジ部を動かして可動板50の向きを変化させながら、対角上に位置しない2つのラインセンサの光量変化があるか否かを判断し、光量変化がない位置に可動板50を位置決めする。【選択図】図2
