<p>The present invention relates to a stylus pen touch timing detecting type touch screen input device for inputting a user command into a touch screen. In particular, by distinguishing a touch by a stylus pen and a touch by a hand holding the stylus pen, each of which generates a touch sensing signal, a stylus pen touch timing detecting type touch screen input device given in the present invention can selectively receive an input through a touch by the stylus pen only. Also, the stylus pen touch timing detecting type touch screen input device detects the touch pressure by a pen tip when the stylus pen touches the device, and the intensity is delivered to a terminal. The terminal receives an input only when the intensity of the touch pressure is greater than a certain value. At the same time, depending on the intensity of the touch pressure, the stylus pen touch timing detecting type touch screen input device adjusts the characteristics of a user command such as the line width, thereby enabling smooth writing and sketching.
