Embodiment Construction
[0020] Such as figure 1 The optical detection device for mouse displacement and button information includes an optical sensor 4, a light source 1, an illumination optical path, at least two control optical paths and an optical path micro switch 6, and the light source 1 is irradiated in the sensing window of the optical sensor through the illumination optical path To form (displacement) detection images, the optical path micro switch 6 is set on the control optical path to control its on-off. It can be seen from the figure that a part of the light emitted by the light source 1 is directly irradiated in the sensing window of the optical sensor, and this part of the light The optical path is the lighting optical path; the other part of the light emitted by the light source 1 is divided into multiple parts by the beam splitter 5 and then incident into the conduction fiber. The optical path micro switch 6 is set on the conduction fiber. After control, the light is irradiated in th...

An optical detection device for mouse displacement and button information, involving the structure of the mouse, including an optical sensor, a light source, an illumination optical path, at least two control optical paths and an optical path switch, the light source is irradiated by the illumination optical path in the sensing window of the optical sensor to form a detection image , the optical path switch is set on the control optical path to control its on-off, the control optical path is irradiated in the sensing window of the optical sensor to form an optical code image after being controlled by the optical path switch, and the detection formed by illuminating the optical path in the sensing window of the optical sensor Images are superimposed or stitched to form a combined image that is recognized by an optical sensor. The invention has the advantages of simple structure, less material consumption, low manufacturing cost, long service life, and less failure.
Description
technical field [0001] The invention relates to the structure of a mouse, and in detail is an optical detection device and method for mouse displacement and key information with simple structure, material saving, low manufacturing cost and long service life. Background technique [0002] In the industrial field, optical sensors such as cameras are used for object detection and movement monitoring, and the mouse in work and life is a typical optical sensor application device. The existing mouse has two basic detection systems of optical displacement detection and electric button detection, and the information of the two systems is processed through the mouse control unit to obtain mouse movement and mouse click instructions. There is an opening under the optical sensor of a common mouse, and this area is the observation window of the optical sensor. When the mouse is working, the light source illuminates the optical sensor window, and the image in the window is imaged on the...
