<P>PROBLEM TO BE SOLVED: To provide an input device that does not limit writing tools to be used therefor and can record a movement locus of a usually used writing tool only by directly writing a note on a sheet placed in a frame using the writing tool and store the locus as electronic data. <P>SOLUTION: An input device D comprises an optical sensor S that includes a rectangular frame 1 on which a hand is to be placed in writing with a writing tool W and at least a pair of a light-emitting element and a light-receiving element and that detects blockage, which is caused by the writing tool W in the frame 1, of light reaching from the light-emitting element to the light-receiving element, so as to output positional information on the writing tool W in the frame 1. When a note is written on a part of a sheet P exposed from the inside of the frame of the optical sensor S by using the writing tool W or the like, a movement locus by the tip of the writing tool W is stored in storage means M as electronic data. <P>COPYRIGHT: (C)2013,JPO&INPIT |
