Abstract:
A projector includes a first detection section which has a first sensor provided to an enclosure, and has a first detection axis as a central axis of a first detection range as a detection range of the first sensor, and a second detection section which has a second sensor provided to the enclosure, and has a second detection axis as a central axis of a second detection range as a detection range of the second sensor, and a distance of the first detection range from the first sensor in the first detection axis of the first detection section is longer than a distance of the second detection range from the second sensor in the second detection axis of the second detection section.
