[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a kind of mouse, and more particularly to a mouse having a structure in which a fence ring, a light source, and a light receiving sensor are attached to a circuit board and can be easily assembled.

[0002]

[Prior art]

 There are three types of conventional mice, mechanical type, optical type, and semi-optical type. Among them, the semi-optical type mouse has one circuit board installed inside the mouse body and one mouse on the bottom of the mouse body. A hole is pierced and one rubber ball is rotatably installed in the hole so that the face appears downward, and a pair of encoders are installed in the mouse body. Had a configuration in which it was provided with one fence ring that was extended toward the rubber ball and formed rotational friction with the rubber ball to rotate simultaneously with the rotation of the rubber ball.

Further, in the conventional semi-optical mouse, a light source and an optical sensor are provided beside each of the fence rings, and the light source emits the emitted rays perpendicularly to the fence wheel. The optical sensor is installed around the fence ring and receives light rays emitted from the periphery of the fence ring.When the fence wheel rotates, the light emitted from the light source is not reflected on the fence ring. Either the light is blocked by the light-transmitting portion, or the light sensor passes through the light-transmitting portion and is received by the optical sensor. In these two situations, 1 is displayed as light-transmitting and 0 is displayed as non-light-transmitting (1, 1). , (0,1), (0,0), and (1,0) are represented as four signals. These signals are converted through the circuit board and then moved on the mouse cursor moving on the screen. It is used to There are two sets of encoders, each of which controls the movement in the horizontal and vertical directions or the movement in one of the directions on the screen. However, in the well-known mouse described above, the relative position between the fence, the light source, and the optical sensor affects the accuracy of signal reading, and if there is a deviation in their attachment, detection failure or failure may occur. I was afraid. And in the known technology, the fence ring, the light source and the optical sensor are directly mounted on the circuit board, which makes the assembly troublesome and often requires cost and time to make adjustments until the positioning of these elements is completed. It is also inconvenient in production and manufacturing because it causes the situation.

[0004]

[Problems to be solved by the device]

 The main object of the present invention is to provide a kind of mouse in which a fence ring, a light source and an optical sensor can be quickly assembled on a circuit board and no adjustment is required.
