  FIG. 1 is a cross-sectional view of an optical structure of a conventional optical mouse. The optical structure 1a is installed in a frame 2a of an optical mouse, and includes a lens base 3a, an LED element 4a, and an image sensing element 5a. The lens base 3a is installed at the bottom of the optical mouse frame 2a. The first lens 31a is provided corresponding to the position where the LED element 4a emits the emitted light, and the image sensing element 5a receives the reflected light. And a second lens 32a provided corresponding to the position to be moved.

  In this structure, the emitted light from the LED element 4a is bent by the first lens 31a, irradiated to the reflecting surface 6a (table surface), and reflected by the reflecting surface 6a, whereby reflected light is formed. The The reflected light further reaches the reflected light receiving position of the image sensing element 5a via the second lens 32a.

However, the conventional structure as described above has the following problems.
That is, the light emitted from the LED element 4a is emitted radially and reaches the image sensing element 5a via the first lens 31a, the reflecting surface 6a, and the second lens 32a. Therefore, optical loss occurs in the optical signal during the transfer process. That is, all of the emitted light from the LED element 4a cannot reach the image sensing element 5a via the lens base 3a.
When the optical signal becomes weak in this way, there is a problem that the sensitivity and analysis of the image sensing element 5a are lowered, and the function of the optical mouse is adversely affected.

  Further, the lens base 3a has a problem that not only the cost is high, but the volume of the entire optical structure is increased thereby.

  In addition, when the conventional optical mouse is used on a smooth surface, the mouse does not always work normally (function), and the movement of the mouse cannot be accurately grasped by optical image analysis transmitted to a computer. was there.

  As described above, the conventional optical mouse has a problem to be solved.

  Therefore, the present inventor has carefully studied based on abundant years of practical experience, and proposed a device that can solve the problems of conventional technology effectively and rationally according to the theory. To do.

  The object of the present invention is to provide an optical structure of a mouse that can realize a reduction in cost and volume, particularly with an optical structure that has a tuning light source and omits a lens set. It is to provide a mouse that has a tuning light source to improve the sensitivity of the mouse and can be operated on various surfaces.

In order to achieve the above object, an optical structure of a mouse according to the present invention is an optical structure of a mouse installed inside a mouse, which is installed on a base body and the base body, and radiates emitted light onto a work plane. The tuning light source includes a tuning light source that is reflected by the work plane to be reflected light, and an optical sensor that is installed on the base body and is positioned in the path of the reflected light.
In order to achieve the above object, a mouse according to the present invention includes a frame, a base body installed inside the frame, the base body, and a work plane irradiated with emitted light, It is characterized by comprising a tuning light source in which emitted light is reflected by the work plane and becomes reflected light, and an optical sensor installed on the base body and positioned in the path of the reflected light.

  In a preferred embodiment, the tuning light source is a solid-state laser, and the incident angle of the emitted light is preferably between 15 degrees and 75 degrees. The tuned light source is intended to improve the sense function of the mouse and the sensitivity of the mouse, so that the mouse can work on various surfaces.

  The optical sensor includes a light receiving unit, and the light receiving unit is provided in a path of reflected light. Thereby, the light emitted from the tuning light source is reflected by the work plane and then directly reflected by the light receiving portion of the photosensor. Therefore, the emitted light from the tuning light source is transferred to the light receiving unit of the optical sensor without being guided by the lens set. Therefore, since the lens set can be omitted, the cost for the lens set and the occupied space can be saved.

  Hereinafter, the features and technical contents of the present invention will be described in detail with reference to the drawings. However, the drawings and the like are merely for reference and explanation, and the present invention is not limited thereby. .

  According to the present invention, it is possible to obtain an optical structure of a mouse that has a tuning light source and omits a lens set, and can realize cost reduction and volume reduction, and also has a mouse sense function and mouse sensitivity. A mouse can be obtained that has a tuned light source to enhance and can operate on various surfaces.

  FIG. 2 is a cross-sectional view of a first preferred embodiment of a mouse and its optical structure according to the present invention. A mouse 100 according to the present invention includes a frame 1 and an optical structure 2. The optical structure 2 is installed inside the frame 1, and includes a base body 21, a tuning light source 22, and an optical sensor 23. The mouse 100 may be a brush optical mouse or a bucks optical mouse.

  The frame body 1 has an upper lid 11 and a bottom seat 12, and an opening 121 is formed in the bottom seat 12. The base body 21 is integrally molded, and a storage chamber 211 is formed therein. The base body 21 is installed on the bottom 12 so that the storage chamber 211 is positioned above the opening 121.

  The tuning light source 22 is a solid-state laser. When the solid-state laser is used as a light source, the sensitivity of the mouse to the object surface is improved. Therefore, even when the mouse 100 moves on a smooth surface, shift information can be accurately supplied to the computer. In addition, since the mouse 100 can grasp the surface information of the object more accurately, the problem that the conventional mouse cannot grasp the position information accurately on a smooth surface can be solved.

The tuning light source 22 is installed on the base body 21, and the emitted light 221 from the tuning light source 22 is irradiated to the work plane 4 through the opening 121 and reflected by the work plane 4, and then the reflected light 222 is reflected. Form. Note that a preferable incident angle α of the outgoing light 221 with respect to the work plane 4 is between 15 degrees and 75 degrees. In the first preferred embodiment shown in FIG. 2, the incident angle α is 15 degrees.
Further, since the outgoing light 221 from the tuning light source 22 is tuning light, after the outgoing light 221 is reflected by the work plane 4, a reflection angle β equal to the incident angle α is naturally formed.

  The optical sensor 23 is installed on the base body 21 and is located in the path of reflected light. The optical sensor 23 includes a light receiving unit 231, and the light receiving unit 231 is located in the path of the reflected light and receives the reflected light 222. That is, no matter how the optical sensor 23 is installed, the light receiving unit 231 is positioned in the path of the reflected light, so that the purpose of receiving the reflected light 222 is achieved. Therefore, in this embodiment, if the incident angle α is set to 15 degrees, the light receiving unit 231 may be located at any position in the path of the reflected light whose reflection angle β is 15 degrees.

  The mouse 100 further includes a circuit board 3. The circuit board 3 is electrically connected to the tuning light source 22 and the optical sensor 23 and functions to drive the mouse 100.

When the mouse 100 slides on the workpiece plane 4, the emitted light 221 of the tuning light source 22 enters the workpiece plane 4 from the opening 121 of the bottom seat 12 at an incident angle α. The incident angle α determined in advance is determined by the designer, and the designer can select an angle that can enhance the characteristics of the surface of the workpiece plane 4, thereby improving the sensitivity of the mouse. .
The reflected light 222 formed by the emission light 221 from the tuning light source 22 reflected by the work plane 4 is directly received by the light receiving unit 231 of the optical sensor 23 through the opening 121.

  Thus, the emitted light 221 from the tuning light source 22 is reflected directly on the work plane 4 to the light receiving unit 231 of the optical sensor 23. Therefore, the emitted light 221 from the tuning light source 22 is transferred to the light receiving unit 231 of the optical sensor 23 without being guided by the lens set. Therefore, in the optical structure 2, the conventional lens set of the optical structure of the mouse can be omitted, and cost and occupied space can be saved. Therefore, the design of the optical structure 2 of the mouse 100 realizes cost reduction and volume reduction.

It only has to be located. That is, the light receiving unit 231 may be located at any position in the path of reflected light having a reflection angle β of 45 degrees.

  FIG. 5 is a sectional view of a fourth preferred embodiment of the mouse and its optical structure according to the present invention. In the fourth preferred embodiment, the optical sensor 23 is provided in a horizontal state. For this reason, even if the incident angle is 15 degrees, 30 degrees, or 45 degrees, the light receiving unit 231 may be positioned in the path of the reflected light 222.
