Noiseless mouse based on infrared sensing technology

The invention discloses a noiseless mouse based on an infrared sensing technology. Infrared geminate transistors are used to replace a microswitch of a traditional mouse to achieve the purpose of eliminating noise. The problem to be solved is about receiving of an infrared geminate transistor device signal. According to the solution, the traditional mouse is designed to be of a double-layer structure, an oval hole with a long axis size about 3cm is designed in each of a left key and a right key of the outer layer, a small round hole with the size of about 1cm is designed in each of the corresponding positions of the inner layer, the microswitch of the traditional mouse is removed, a reflective infrared geminate transistor device is arranged under each small hole, a slidable sliding sheet is placed between the two corresponding holes in the inner layer and the outer layer, and a hole is also formed in the sliding sheet; when the sliding sheet slides, an outer shell, the sliding sheet and an inner shell can rea
