<P>PROBLEM TO BE SOLVED: To provide an input device capable of recording a movement locus by a usual writing tool or the like only by directly writing a note or the like on a sheet placed in a frame using the writing tool and storing the locus as electronic data. <P>SOLUTION: An optical sensor S1 of an input device D1 includes: a rectangular frame 1; a light-emitting side optical waveguide 4 and a light-receiving side optical waveguide 5; and a light-emitting element (light source 2) and a light-receiving element (light-receiving element array 3) attached to the light-emitting side optical waveguide 4 and the light-receiving side optical waveguide 5, respectively. One of portions facing each other of the frame 1 has plural light-emitting cores 4a and 4b formed thereon, and the other of the portions has light-incident cores 5a and 5b formed thereon. The tip portion of each core is positioned on the inner edge of the frame 1 so that the tip portions of the cores 4a and 4b face the tip portions of the cores 5a and 5b. When a note is written on a part of a sheet P exposed from the inside of the frame of the optical sensor S1 by using a writing tool W or the like, a movement locus by the tip of the writing tool W is stored as electronic data in storage means M mounted in the input device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
