PROBLEM TO BE SOLVED: To provide a projector acquiring a position on the image of an object to be detected, in which even when a projection device and a detection device are installed separately from each other, the detection device can be installed in a state of having a proper position and direction with respect to the projection device.SOLUTION: A projector 100 includes a projection device 10 including a laser light generation part 12 outputting laser light for projection (display image 40) and laser light for positioning (line image 52) and a scanning part 14 scanning the laser light and projecting the display image 40 and an optical sensor device 20 provided separately from the projection device 10 and including a light-receiving part 22 receiving the laser light for projection reflected by an object to be detected 60. The optical sensor device 20 further includes a sign part 21 provided so as to be aligned with the laser light for positioning (line image 52) applied from the projection device 10. |
