摘要：An optic mouse includes a housing having a bottom casing and a top covermounted to the bottom casing, a circuit board mounted in the housing and a lens setmounted on the bottom casing. The bottom casing defines an opening. A detectingdevice is mounted to the circuit board and has a receiving portion in alignment with the
opening of the bottom casing. A vertical cavity surface emitting laser source is arrangedon one side of the detecting device. The lens set includes a convex lens having top andbottom faces respectively opposing the receiving portion of the detecting device and theopening of the bottom casing. The lens set further defines a channel in which a reflectionmember is formed. The channel has an open end opposing the vertical cavity surfaceemitting laser source for receiving optic signals from the laser source. By means of theoptic characteristics of polarity of light emitted by the vertical cavity surface emittinglaser source, together with the lens set, the light gets more convergent and does notdiverge in traveling along an optic path from the laser source to the receiving portion ofthe detecting device whereby the operability of the mouse is enhanced.
