An automatic scrolling type optical pen mouse and an automatic scrolling method thereof are provided to enable a user to perform a scrolling function, and select a scrolling and cursor moving mode without using any finger by performing the scrolling function with movement of the pen-type mouse. A scrolling key input unit(130) inputs a scrolling setting key. A microcomputer(140) calculates coordinates based on an electric signal received from a light receiver(112), and converts the coordinates into a scrolling-up/down signal and outputs the scrolling-up/down signal when the scrolling setting key is received from the scrolling key input unit. The microcomputer includes a controller calculating the coordinates based on the electric signal received from the light receiver, and outputting a code conversion control signal when the scrolling setting signal is received, and a code converter converting the coordinates into a scrolling-up/down code by control of the controller when the code conversion control signal is received from the controller.
