<p><P>PROBLEM TO BE SOLVED: To provide a light pen capable of confirming the start position of writing in beginning to draw letters or the like by using an external instrument capable of displaying the track of a luminous point. <P>SOLUTION: The light pen 1 includes a light emitting part 30 arranged at the tip part of the pen main body 10, for emitting light so as to indicate the position of the tip part of the pen main body 10, a transmission part 40 for transmitting a trajectory display signal for displaying the trajectory of the light emitting part 30, and a stroke-pressure type switch 60 for selectively outputting the trajectory display signal from the transmission part 40. The ON/OFF state of the switch 60 is switched in accordance with the pressurizing force toward the tip part of the pen main body 10. Regarding such the light pen 1, in transmitting the trajectory display signal from the transmission part 40 to the prescribed external instrument capable of displaying the trajectory of the luminous point of the light emitting part 30, a point mark corresponding to the luminous point of the light emitting part 30 can be displayed on a data image displayed on the external instrument from the start. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
