Abstract
Provided are a light-emitting portion having a light-emitting member and a light emergence surface through which light from the light-emitting member emerges, and a light-receiving portion having a light incidence surface through which the light from the light-emitting member enters and a light-receiving member that detects the light entering through the light incidence surface. The light-emitting portion and the light-receiving portion can make relative movement between a measurement position in which the light emergence surface and the light incidence surface make contact with each other and a waiting position in which the light emergence surface is away from the light incidence surface. When the light-emitting portion and the light-receiving portion are in the measurement position, the light emergence surface and the light incidence surface make contact with each other at a point.
