Abstract:
1. An optical input device comprising: a substrate which defines an information input region by a touch operation; an optical sensor which optically scans the information input region and detects a selectively touched position on the substrate; a region setting unit which sets, in the information input region, a specific information input region individually specifying information to be input and an input mode switching region used for changing an information input mode, and displays each of the regions to be visible; an input mode switching unit which detects the touch operation in the input mode switching region according to an output of the optical sensor, and selects and sets an input mode of information through the information input region from a plurality of preset input modes; and an input processing unit which analyzes the output of the optical sensor according to the input mode set in the input mode switching unit to find out the information input by the touch operation in the information input region.
