PROBLEM TO BE SOLVED: To provide a projection device that can accurately detect a contact position on an image projection surface of an operation execution object on a projection image.SOLUTION: A projection device 1 includes light source modules that includes a laser light source emitting laser beams (a first light source module 8, and a second light source module 9), light deflection means 11 for two-dimensionally scanning a laser beam emitted from the light source modules to project a projection image 6 on an image projection surface 5, light detection means 3 for detecting reflected light of a laser beam from an operation execution object 7 on the projection image 6, and a control unit 20 for determining a position on the projection image 6 with which the operation execution object 7 has been brought into contact from information from the light detection means 3 and information on the projection image 6. |
