<P>PROBLEM TO BE SOLVED: To provide a luminescence pen which has a simple structure, decreases failure occurrence, keeps two luminescence sections embedded in an LED unit, and lightness excellent, prevents shadow from occurring, and makes operation of on-off easier than with a luminescence pen of a conventional mechanical type switching device. <P>SOLUTION: An LED 5b which keeps two luminescence sections 11a embedded and emits light is attached on the tip opening of a pen body which stores a mechanical pencil for note and a ball-point pen core, a negative pole of this LED unit 5b is directly connected to a battery 9 through an internal metal sheet, spring or the like of a pen, a positive pole is connected to an IC substrate 8 between an LED unit 5b and the battery 9, and on-off is carried out by a sense of a touch sensor 1a. <P>COPYRIGHT: (C)2008,JPO&INPIT |
