<p>PROBLEM TO BE SOLVED: To provide an optical touch panel of high resolution. SOLUTION: An optical touch panel 100 is provided with a light-transmitting plate 102, horizontal/vertical light-emitting element streams 104X and 104Y, a light-receiving element 108 provided at one corner of the light-transmitting plate, horizontal/vertical optical path change members 106X and 106Y for changing the optical path of light from the horizontal/vertical light-emitting element to the direction of the light-receiving element, and a detector 110 for detecting the touch position of an input means from the change of horizontal and vertical light caused by the touch of an input means 114 to the light-transmitting plate 102. Thus, since light can be guided stably through the light transmission plate, an optical touch panel which stably and exactly operates can be provided. Further, since the light-emitting part and the light-receiving part can be miniaturized, the device can be miniaturized and reduced in power consumption.</p> |
