PURPOSE: A multiple function mouse is provided to make a movement to a next screen or a previous screen shifted into a required screen easily without any movement of a mouse pointer by pushing a previous screen button or a next screen button. CONSTITUTION: In a multiple function mouse, a button is formed at one side of a mouse, and is composed of a next screen button, an up button and a down button. An I/O module part generates an electric signal by a movement of a ball embedded in the mouse and a pushing of the button. A controller(300) converts the electric signal into a data value, and a clock generator(400) generates a constant frequency in order to receive the electric signal periodically. A data transmitter and receiver(500) receives the converted data value and the frequency to transmit the converted data value into a computer according to the frequency. |
