Abstract
The present invention relates to a capacitive touch input device utilizing the capacitive sensing method for detecting touch inputs from a finger or a similar conductive object. More specifically, it pertains to a capacitance detection device designed to facilitate the detection of touch coordinates based on the vertical movement of a pen by employing a capacitive detection sensor composed of a composite trapezoidal shape.
