Abstract

The optical mouse in improved structure includes one casing and one circuit board. The casing is the combination of one upper cover and one bottom seat with bottom part of transparent medium; and the circuit board is fixed inside the casing and has one integrated circuit with receiving part, extending arm on one side and light source for lighting on the extending arm. The light beam of the light source is in the first angle to the bottom part of the bottom seat, and under the integrated circuit, there is one convex lens with upper surface opposite to the receiving part of the integrated circuit and lower surface opposite to the intersection point between the light beam and the bottom part.

Description

technical field [0001] The invention relates to an improved optical mouse, in particular to an optical mouse in which a lens and a sensing integrated circuit are integrally formed. Background technique [0002] FIG. 1 is an exploded perspective view of a known optical mouse, which includes a casing 1 , a circuit board 2 , a lens group 3 and a barrier layer 4 . The casing 1 is composed of an upper cover 11 and a base 12 , and a through hole 121 is opened on the base. The circuit board 2 is fixedly installed in the above-mentioned housing 1, the circuit board 2 is provided with an inductor 21 having a receiving portion 211, and on the side adjacent to the inductor 21 is provided with a sensor on the same surface as the receiving portion. A surface emitting laser light source 22 (VCSEL, Vertical Cavity Surface Emitting Laser) or a light emitting diode 22 (LED), and the receiving portion 211 of the sensor 21 corresponds to the through hole 121 . [0003] The lens group 3 is ar...
