The present invention relates to an apparatus for detecting a touch point of a touch panel, used for a reflective camera-type touch panel. More particularly, the present invention relates to an apparatus for detecting a touch point of a touch panel, wherein a portion or the entirety of a retroreflective tape used for reflection has a sawtooth shape to thereby remove the restrictions on the length ratio of the longer side to the shorter side of the touch panel and on the size of the touch panel. |
