PURPOSE: A pen-typed optical mouse device equipped with a supporter is provided to offer an optical path and an optical part arrangement for correctly transferring an image formed on the bottom to an optical sensor array, and offer convenience like using a pen. CONSTITUTION: An optical module(180) comprises the first and the second condensing lens(150,160). The first condensing lens condenses the image reflected from the bottom. The second condensing lens is made by combining a prism surface(161) and a surface of the first condensing lens as one body in order to correctly transfer the light passing the condensing lens to the optical senor array(131) of an optical sensor. An LED(Light Emitting Diode) guide surface(102) prevents light of a light source from scattering to surrounding and collects the light to a designed position. |
