Abstract

PURPOSE:To obtain a coordinate input device simplified at its use and having high efficiency by using the two-dimensional array of fluorescent fibers. CONSTITUTION:The one ends of fluorescent fibers x1-xn, y1-yn two- dimensionally arrayed and fixed in a transparent plate (e.g. acrylic resin) 11 are connected respective light receiving arrays 12 and the other ends are covered with reflecting films so that incident light into the fluorescent fibers is efficiently inputted to the arrays 12. When a light emitting part 14a of a light pen 14 is abutted upon a specified display part on the plate 11, light beams 24 from the light emitting part 14a are made incident upon the fibers arranged on the lower part of the display part and transmitted through respective fibers and the beams projected from one ends are detected by the arrays 12. Consequently, the constitution can be simplified, writing (input) accuracy can be improved and the reliability of the two-dimensional coordinate input can be also improved.
