To obtain a feeling that a device for designating coordinates reaches a display surface even if the device for designating coordinates is prevented from reaching the display surface.

When the distance between a coordinate designation device 1 and an information processor 2 is equal to or greater than h1, the length of a part of a designation part 14 that protrudes from the coordinate designation device 1 is L1. When the distance between the coordinate designation device 1 and the information processor 2 is less than h1 and equal to or greater than h2, the distance of a part of the designation part 14 that protrudes from the coordinate designation device 1 is not changed. When the distance between the coordinate designation device 1 and the information processor 2 is less than h2, the distance of a part of the designation part 14 that protrudes from the coordinate designation device 1 is L2, which is shorter than L1. The difference between L1 and L2 is the same as the thickness of a protection layer 23.
