By using a display 11 where optical sensors 34 are embedded in multiple light-emitting blocks 29 and an optical imaging means 13 where multiple first and second minute reflecting surfaces 20, 21 intersecting with each other in a plan view are respectively disposed upright on a same plane, an image 11a of the display 11 is formed as a first real image 12 on one side of the optical imaging means 13, an image of pointing means 45 in contact with the first real image 12 is formed as a second real image 45a on the other side of the optical imaging means 13, and the position of the second real image 45a is detected by the optical sensors 34 of the display 11. |
