The present invention provides a touch control position determining method which allows the touch control position to be determined precisely regardless of the modes of control. When a touch control is made on an input pad, it is confirmed whether or not the upper and lower vertical position detecting lines are in the non-detected state in which infrared rays are not intercepted to determine whether the touch control position is located at the upper side, the center or the lower side (Steps 100 through 112). Next, it is confirmed whether or not the right and next horizontal position detecting lines are in the non-detected state to determine whether the touch control position along the horizontal direction is located at the left side, the center or the right side (Steps 114 through 122). Thus, the touch control position in the vertical and horizontal directions is determined and the determination result is outputted (Step 124).
