PROBLEM TO BE SOLVED: To position a longitudinal direction of a light guide.SOLUTION: A first light guide for reflection light 21a includes a shank 28 as an end and a body 22, is linear stick-shaped including the end and the body 22, and lets light from a first light source for reflection light 36a go into it from the end and go out of it from the body 22. The end of the first light guide for reflection light 21a is thinner than the body 22, and includes abutting face 29 touching with a cap 45. The cap 45 includes a light source side opening 51, the first light source for reflection light 36a is disposed in the light source side opening 51, and the first light source for reflection light 36a faces the abutting face 29.SELECTED DRAWING: Figure 8 【課題】導光体の長手方向を位置決めすることを目的とする。【解決手段】第１反射光用導光体２１ａは、端部としての軸部２８と本体部２２とを備え、端部および本体部２２を含めて直線状の棒状であり、第１反射光用光源３６ａからの光が端部から入り本体部２２から出る。第１反射光用導光体２１ａの端部は、本体部２２よりも細く、キャップ４５と接する当接面２９を有し、キャップ４５は光源側開口５１を有し、光源側開口５１は第１反射光用光源３６ａが配置され、第１反射光用光源３６ａは当接面２９と対向することを特徴とする。【選択図】図８
