Cursor position. A general optical mouse has an optical lens unit and a light emitting/receiving module inside the casing, and the light emitting/receiving module controls at least one LE:D light source to emit the concentrated light, and then a plurality of mirrors passing through the optical lens unit After the light is reflected by various angles, the light passes through the light inlet and outlet holes of the housing base and falls on a surface, and the surface reflects the light through the light inlet and outlet holes into the outer casing, and is emitted by the light emitting/receiving module. The electronic sensor element senses to calculate the displacement of the mouse. The light entrance and exit hole is a through hole provided in the base of the housing. Generally, the optical mouse moves the base to contact the surface of the desktop, the mouse pad or other objects. Therefore, after being used for a period of time, it is attached to the desktop. Micro-organisms such as dust, hair, dander, etc. on the surface of the mouse pad or other objects can easily accumulate on the edge of the light entering and exiting holes, thereby disturbing the entry and exit of the light and affecting the interpretation of the displacement; the user must periodically clean and use it. trouble. In addition, the penetrating light in and out of the aperture also provides the opportunity for liquid to enter the mouse housing, causing internal component failure. 3 M422702 The new patent No. 17525 of Taiwan applied by the applicant of the present application provides a dust-proof input device optical lens module that solves the aforementioned problems.
