<P>PROBLEM TO BE SOLVED: To provide a light irradiation device excellent in portability and capable of precisely and reliably erasing or changing a color of a desired part in use feeling equivalent to that with a small stationary such as a pen, an eraser, or a stamp. <P>SOLUTION: The device is provided with, inside a cylindrical pen type body 40 with an opening at either end: a light irradiation part 10 forming a path of light from a light source; a control circuit part 20 carrying out lighting control of the light source; and a power source part 30 feeding power to the light source through the control circuit part 20. Out of them, the light irradiation part 10 is to be structured of: a discharge tube 11 arranged inside a tip end of the body 40 along a longitudinal direction of the body 40; a parabolic cylinder-shaped reflector 12 arranged so as to surround the discharge tube 11 with a position of the discharge tube 11 as a focal point; and a translucent window 13 positioned in front of an opening of the reflector 12, and fitted into the body 40 with the same direction as a longitudinal direction of the reflector 12 as the longitudinal direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
