PURPOSE: A system for transferring a signal is provided to perform a function corresponding to lots of keys by using a small number of keys by classifying the keys into a general key and a combination key, and recognizing the key press through touch. CONSTITUTION: A display part(100) displays the function mapped at the general key combined with the combination key as a picture, a character, and a symbol by an input signal of the combination key. An input part(200) visually displays the function mapped at the general key displayed on the display part through the transparent key or a transparent window around the key, and recognizes the key input through the touch by forming the key with a button. A signal transferring part(300) directly transfers the input signal of the general/combination key from the input part to a device, or transfers a converted signal fit to the device through wire/wireless to the device.
