Zusammenfassung:	Safety of a user or the like is secured even when such malfunctions as a case that an optical system member has gone out of place occur. Provided is a protection cover which covers a light source device including a light source, an emitting section which is an optical system member that converts light of the light source into diffused light to emit the light, and a light receiving section that senses the light of the light source reflected by the emitting section. The protection cover which covers the light source device includes an opening arranged adjacent to the emitting section and having a shape that allows transmission of the emitted light and also that prevents a finger of a person from contacting the emitting section.
