To provide an optical information reading device inputting information to a display area in a display screen.

A paper sheet 50 displayed with a plurality of position information codes C each disposed inside a prescribed area 51, each having position information related to a position disposed in the prescribed area 51 is previously prepared. When at least one of the respective position codes C is read, a central position Lo of illumination light Lf to the prescribed area 51 is calculated as a reading position based on the position information of the position information code C. By associating positional relation between the prescribed area 51 and a display area 46a, a cursor K is made to be moved to an information input position in the display area 46a corresponding to the reading position calculated as above.
