Abstract

An attached matter detector (10) includes a plurality of light-emitting elements (11A to 11H, 41 A to 41D) which are aligned linearly and emit light; a plurality of collimator lenses (12A to 12H) which are aligned linearly corresponding to the light-emitting elements (11A to 11H, 41A to 41D), respectively, and collimate the light emitted from the light-emitting elements (11A to 11H, 41A to 41D) as collimated light (L), and emit the collimated light through one surface (17A) of a transparent plate member (17) to the other surface (17B) of the transparent plate member (17); one light-receiving element (15) which receives reflected light (L') from the other surface (17B) of the transparent plate member (17); and an attached matter determiner (16) which determines whether attached matter (S) is attached to the other surface of the transparent plate member (17) or not from the reflected light (L') received by the light-receiving element (15).
