Therefore, it is preferable that the masking detection structure is configured such that at least part of the light emitted from the light source is guided to the light receiver in a normal state in which the masking material is not detected. With such a configuration, it is possible to detect both a masking material that increases the amount of received light and a masking material that decreases the amount of received light.
