Zusammenfassung:	PROBLEM TO BE SOLVED: To solve problems that, for example, a conventional light pen is not suitable for writing in dark because it has a light at its hip part, and ink in it is reduced soon because a button cell is inserted into it, therefore an ink core stored in it is shorter than a normal length of a normal ink core, and the button cell cannot be replaced even it runs out, and the conventional light pen is generally disposable, resulting in unsatisfaction for a user.SOLUTION: Because the LED is attached to a tip end of the pen, it is suitable for writing letters even in dark or during night working. In addition, when a lid is attached to the pen, it may be used as a flash lamp and useful during blackout or earthquake disaster as a disaster prevention product. Ink core has length equal to that of a normal ink core, so the pen can be used in long terms. If the ink and the cell run out, they can be replaced.
