<p>PURPOSE: A pen-typed mouse device for a computer or an electronic device is provided to prevent performance degradation of an image sensor by forming a structure to prevent scattered light from coming in the image sensor and design user's convenience by enabling a user to use a pen mouse on diverse angles. CONSTITUTION: A sub-light source(21) emits the light. The image sensor(22) detects/converts the light emitted from the sub-light source into an electric signal. A light iris(23a) filters the unwanted light from the light reflected from a bottom. To prevent the scattered light generated in the sub-light source from coming in the image sensor, a light guide module(23) is formed to an end of the pen mouse main body(20a) by being extended from the image sensor.</p> |
