ABSTRACT:
An optical mouse includes a bottom casing, a top cover mounted to the bottom casing to define an interior space. A circuit board and a lens set are located in the interior space. The bottom casing has an opening. A detecting device is mounted to the circuit board. A receiving portion and a light emitting diode (LED) are mounted to a bottom side of the detecting device in alignment with a slot in the circuit board. A solder pad to which an electrical conductor is connected has a central bore and is positioned on a circumferential margin of a light projection surface of the LED to allow light projected from the light projection surface to transmit through the central bore. The lens set is located between the circuit board and the bottom casing, and includes a reflection member and a lens.
