An input apparatus 100 includes: a light source 10 that emits detection light 17 toward a first direction, and raster scans a detection interface 400 defined in space, with the detection light 17; a first light sensor 20 that is disposed closer to the light source 10 than the detection interface 400, and detects first reflected light 18 which is the detection light 17 that has been reflected; a second light sensor 30 that detects second reflected light 19 which is the detection light 17 that has been reflected off an instructing body 70 that has entered a detection region R extending from the detection interface 400 toward the light source 10; and a control unit 40 that detects a coordinate value of the instructing body 70 using received-light data obtained by the first light sensor 20 and the second light sensor 30 receiving light at the same timing. |
