Abstract
A coordinate inputting/detecting apparatus, for optically detecting a position of a designating device inserted into a flat or substantially flat two-dimensional coordinate inputting/detecting area, and including a coordinate determining device to determine two-dimensional coordinates of the designating device in the area. A distance determining device determines a distance of the designating device from a surface of the area when the designating device is located on or in vicinity to the area. A storing device stores information of the determined coordinates and information of the determined distance. A coordinates change detecting/storing device detects and stores a change of the coordinates information. A distance change detecting/storing device detects and stores a change of the distance information. A state allocating device allocates at least one designating state among designating states of the designating device stored in advance, based upon the coordinate change and distance change information.
