Description

M247947 V. Creation Instructions (1) I. [Technical Field of New Type] This creation is about a lens structure of an integrated optical mouse, especially a light source unit and a sensing unit that can integrate the optical mouse into one. The chip module and the lens module are used to shorten the transmission path of the light source signal, so that the light source emitted and refracted by the light source can be more concentrated without causing the phenomenon of dissipation, so that the optical mouse has a better use effect. I. [Previous technology] / Press. Generally, the existing optical mouse is mainly combined with optical technology to replace the traditional mouse's slide ball. Figures 5 and 6 #, which is a mouse. The optical mouse is mainly composed of a The upper case (the sub-base plate 6 in the picture, the lens group 60 and a circuit board 61, and the lower 61 1 are arranged at a predetermined position with a "two-pole circuit board two sensors" 6 3 (Sensor), and the bottom side of the light emitting diode ^ ED) and the sensor 6 3 (Sensor) is a set of ^ (LED) and the lens group 60; when used, the light emitting diode The signal on the polar body 6 ^ plate 6 is refracted by the light 03 from the first lens of one of the lens groups 60 to the desktop 7, and then reflected by the desktop 7 to the mirror 6 and the two lenses δ 0 2 as the sensor. 6 3 received; lens sharp Θ 〇 the second, however, the existing optical slip i mentioned above is different from the circuit board 6 1 is provided with a light emitting diode 6 2, the structure needs to be divided = the light emitting diode 6 2, sensor 6 3 = collar 6 3 and therefore caused

Page 5 = The lens group 60, not only needs to be separately = bottom = position design 2 higher, the setting position of these components is also troublesome and troublesome, and the reflected light path and its effect meet the requirements: precise Sex needs to make it M247947 V. The difficulty of creation description (2) = 11 is because of many restrictions, the optical mouse is still inferior to the general mouse in terms of popularity. And sensing that light? The light emitting diode 6 2 (LED) R 〇3 (Sensor) on the mouse also needs to be provided with a complex lens group to generate diffused conventional optical i to make the light emitted by the light emitting diode 6 2 It is refracted to the tabletop 7 through the first lens 6 and the mirror β〇3, and then is reflected to the second lens 6 〇2 which is f = 0 through the tabletop 7 and is received by the sensor 6 3, so that the two r ά Ϊ The light source of the body 6 2 is refracted to the sensor 6 3th temple, and its light emitting diode _ β 9 1 source has a long path to refract to the sensor 63 3, which causes the light diode 6 2 to emit and refract the light source. Insufficient concentration, more complicated components and high production costs; therefore, the mouse cannot meet the needs of users. 3. [New Content] The main purpose of Jie Bian's creation is to provide an integrated optics, especially a light source and a sensor 1 module for optical mouse.
