Mouse (Saggar)

Technical Field

The present invention relates to an input device, and more particularly, to a mouse capable of controlling cursor movement.

Background

Common peripheral input devices of a computer include a mouse, a keyboard, a trackball, etc., wherein the mouse is held by a palm of a user to control the movement of a cursor, which is in accordance with the operation habits of most users, so that the mouse is the most common input device.

First, the structure and function of the conventional mouse will be described, please refer to fig. 1, which is a schematic structural diagram of the conventional mouse connected to a computer system. The computer system 2 includes a host computer 21 and a computer screen 22, the host computer 21 is connected to the mouse 1 and the computer screen 22 respectively, the host computer 21 has a port 211, and the computer screen 22 can display a window 221 and a cursor 222 therein. The mouse 1 is capable of controlling the cursor 222 in response to the operation of the user, so that the host computer 21 can execute the corresponding command, and the mouse 1 includes a main body 10, a left button 11, a right button 12, a wheel 13 and a connecting line 14. The left key 11 is disposed on the body 10 and located at the left side of the roller 13, and the left key 11 is exposed outside the body 10 and can be pressed by a user to generate a left key signal. The right button 12 is similar to the left button 11, the right button 12 is disposed on the body 10 and located at the right side of the roller 13, and the right button 12 is also exposed outside the body 10 and can be pressed by a user to generate a right button signal. The roller 13 is disposed in the body 10 and partially exposed from the body 10, and can be rotated by a user to generate a scrolling signal. The connecting wire 14 is disposed on the main body 10 and extends out from the main body 10, and functions to connect to the port 211 to establish a connection between the mouse 1 and the computer system 2.

Next, the internal structure of the conventional mouse will be explained. Please refer to fig. 2, which is a cross-sectional view of a conventional mouse. In the mouse 1, the main body 10 is disposed on the working surface T, and the mouse 1 further includes a main circuit board 15, a sensing module 16 and a control unit 17. The sensing module 16 is disposed on the main circuit board 15 and partially exposed out of the bottom opening 101 of the main body 10, and functions to detect the movement of the main body 10 and output a displacement signal, and the sensing module 16 includes a light emitting element 161, an optical lens 162 and an optical sensing element 163. The light emitting element 161 is provided on the main circuit board 15, and functions to generate the light beam B. The optical lens 162 is disposed in the body 30 and functions to allow the light beam B to pass through and refract the light beam B so as to project the light beam B on the working surface T located below the body 10. The optical sensing element 163 receives the light beam B reflected by the working surface T and generates a displacement signal according to the light beam B. The control unit 17 is disposed on the main circuit board 15 and electrically connected to the optical sensing element 163.

The operation of generating the displacement signal is briefly described. When the mouse 1 is not moved on the working surface T, the light emitting element 161 generates the light beam B, and the light beam B is refracted by the optical lens 162, so that the light beam B is projected onto the working surface T. Next, the light beam B is reflected by the working surface T and enters the optical lens 162 again, and the light beam B passing through the optical lens 162 is received by the optical sensing element 163, at this time, the optical sensing element 163 generates a first working surface image. Next, when the user moves the mouse 1 to a certain position on the working surface T, the light beam B generated by the light emitting device 161 is received by the optical sensing device 163 through the optical lens 162, the working surface T and the path of the optical lens 162, and the optical sensing device 163 generates a second working surface image.

Next, the control unit 17 receives the first working surface image and the second working surface image from the optical sensing element 163, compares the difference between the first working surface image and the second working surface image to obtain the displacement amount of the main body 10 on the working surface T, and generates a displacement signal corresponding to the displacement amount. That is, when the user moves the mouse 1 on the working surface T, the displacement sensing device 16 detects the displacement of the main body 10 on the working surface T and generates a displacement signal according to the displacement. After the host computer 21 receives the displacement signal, the host computer 21 can move the cursor 222 on the computer screen 22 according to the displacement signal.

In response to the development of the mouse, the function of the mouse is increasingly enhanced, for example, the moving resolution of the mouse is greatly improved. The moving resolution of the mouse represents the sensitivity of the cursor of the computer host to move every distance of the mouse, and the larger the moving resolution is, the larger the sensitivity of the cursor to move is. When a user plays a computer game, the mouse needs to be moved quickly, so that the mouse needs high moving resolution; when the user only needs to process words, the mouse only needs low moving resolution. In order to avoid that the user must continuously change the appropriate mouse, a mouse with changeable moving resolution is provided on the market, and the mouse is provided with a switch which is pressed by the user to change the moving resolution of the mouse. For example, when the user touches the switch once, the moving resolution of the mouse is changed from 800dpi (dots Per inc) to 1600 dpi. When the user touches the switch once more, the moving resolution of the mouse is changed from 1600dpi to 800 dpi. Therefore, the mouse can change the moving resolution according to different use conditions.

However, although the moving resolution of the mouse can be changed, the mouse cannot be applied to various working surfaces, such as: the working surface made of transparent material (such as acrylic) will cause the light beam to penetrate, and reduce the reflection of the light beam, so the displacement signal will be affected.

Therefore, there is a need for a mouse that can change the resolution of movement and is adaptable to a variety of work surfaces.

Disclosure of Invention

In a preferred embodiment, the present invention provides a mouse connected to a computer system for controlling a cursor of the computer system, the mouse comprising a housing, a switching module, a main circuit board, a first sensing module and a second sensing module. The shell comprises a shell opening and a support frame, the shell opening is arranged at the bottom of the shell and penetrates through the bottom of the shell, and the support frame is arranged on the bottom of the shell and is positioned in the shell. The switching module is arranged on the support frame and positioned above the opening of the shell and can rotate relative to the shell, and the main circuit board is arranged in the shell and electrically connected with the switching module. The first sensing module is disposed on a first side of the switching module and partially exposed out of the opening of the housing in response to rotation of the switching module. The second sensing module is disposed on a second side of the switching module and partially exposed out of the opening of the housing in response to rotation of the switching module. The switching module can switch the moving resolution of the mouse in response to the first sensing module or the second sensing module being exposed outside the opening of the shell.

In short, the user can control different sensing modules to be exposed out of the opening of the shell according to the requirement so as to select the proper moving resolution. The switching module in the mouse acts by matching a mechanical structure with a simple detection element and a control unit, so the mouse has the advantages of simple structure and low cost. In addition, the first sensing module, the second sensing module and the third sensing module are respectively different types of sensing modules, so that the first sensing module, the second sensing module and the third sensing module are respectively suitable for different types of working surfaces, and therefore, besides the moving resolution, a user can select a suitable sensing module according to the requirement, and the mouse can run on the suitable working surface. In other words, the mouse of the invention not only can change the moving resolution, but also can run on various working surfaces.

The structures of the first sensing module 32, the second sensing module 33, and the third sensing module 34 are explained next. Referring to fig. 3, fig. 4 and fig. 6, fig. 6 is a schematic cross-sectional view of a mouse according to a preferred embodiment of the invention.

Fig. 6 shows a detailed structure of the first sensing module 32, the first circuit board 324 is disposed on the first surface 3513 of the switching cylinder 351, the first cover 325 covers the first circuit board 324 and is fixed on the first circuit board 324, and the first cover 325 has a first opening 3251. The first light emitting device 321 is disposed on the first circuit board 324 and electrically connected to the control unit 355, and functions to generate a first light beam B1. The first optical lens 322 is disposed on the first cover 325 and exposed outside the first opening 3251 for the first light beam B1 to pass through. The first optical sensing element 323 is disposed on the first circuit board 324 and electrically connected to the control unit 355, and is capable of receiving the first light beam B1 passing through the first optical lens 322 to generate a working surface image.

Specifically, the first circuit board 324 may be disposed on the first surface 3513 of the switch cylinder 351 by various bonding methods such as heat fusion, screw locking, etc.; the first cover 325 can also be fixed on the first circuit board 324 by various combination methods, in other words, the components of the first sensing module 32 can be combined into a whole first, and then the first sensing module 32 is disposed on the first surface 3513 of the switching cylinder 351 by the combination of the first circuit board 324 and the switching cylinder 351. Second, similar to the first cover 325, the second cover 335 has a second opening 3351, the third cover 345 has a third opening 3451, and the second cover 335 and the third cover 345 have the same structure as the first cover 325, so the description is omitted.

The second sensing module 33 and the third sensing module 34 are the same as the first sensing module 32, and have two differences: the second circuit board 334 of the first and second sensing modules 33 is disposed on the second surface 3514 of the switching cylinder 351, and the third circuit board 344 of the third sensing module 34 is disposed on the third surface 3515 of the switching cylinder 351. Second, the first light emitting element 321 of the first sensing module 32 is a visible light emitting element, the second light emitting element of the second sensing module 33 is a invisible light emitting element, and the third light emitting element of the third sensing module 34 is a Laser (Laser) light emitting element, and other structures are the same, so that the description is omitted. In other words, the first sensing module 32 is a visible light sensing module, the second sensing module 33 is a invisible light sensing module, and the third sensing module 34 is a laser sensing module.

Next, a case where the operating state of the mouse 3 is changed by the switching module 35 will be described. Referring to fig. 3, fig. 4 and fig. 7, fig. 7 is a partial schematic structural diagram illustrating the operation of the switching module of the mouse according to a preferred embodiment of the present invention. When a user needs a higher moving resolution, the user can toggle the first cover 325 exposed to the opening 301 of the housing, so that the switching cylinder 351 connected to the first sensing module 32 rotates in the first rotation direction C1 relative to the housing 30, and at this time, the second end 3512 of the switching cylinder 351 rotates and drives the rotating element 35 to rotate, so that the second sheet 3532 rotates relative to the first sheet 3531. During the rotation of the switching cylinder 351, the first end 3511 of the switching cylinder 351 rotates in the detecting element 354, and the rotation state thereof is read by the detecting element 354, so that the detecting element 354 outputs a detection signal corresponding to a third state value (e.g., 3) to the control unit 355. The control unit 355 may drive the third sensing module 34 according to the third state value, and control the first sensing module 32 and the second sensing module 33 to enter the sleep mode, i.e., the operation mode of the mouse 3 with high moving resolution. By the above operation of the switching module 35, the third cover 345 overlaps the housing opening 301, so the third sensing module 34 can be exposed outside the housing opening 301.

When the user wants to use the second sensing module 33 in response to the change of the working surface T, the user can use the switching module 35 to perform the above operation to change the mouse 3 to a state where the second sensing module 33 is exposed out of the opening 301 of the housing. Its operation is briefly described as follows: the user pulls the third cover 345 exposed in the opening 301 of the housing, so that the switching cylinder 351 connected to the third sensing module 34 rotates continuously in the first rotation direction C1 relative to the housing 30, and at this time, the second end 3512 of the switching cylinder 351 rotates and drives the rotating element 35 to rotate, so that the second sheet 3532 rotates relative to the first sheet 3531. During the rotation of the switching cylinder 351, the first end 3511 of the switching cylinder 351 rotates in the detecting element 354, and the rotation state thereof is read by the detecting element 354, so that the detecting element 354 outputs a detection signal corresponding to the second state value (e.g., 2) to the control unit 355. The control unit 355 may drive the second sensing module 33 according to the second state value, and control the first sensing module 32 and the third sensing module 34 to enter the sleep mode, so that the second sensing module 33 suitable for the working surface T is operated. The operation of the first sensing module 32 is similar to the above, and is not described again.

It should be noted that the switch cylinder 351 and the second end 3512 thereof are hollow structures, and the hollow structures inside the switch cylinder can accommodate electric wires (not shown) connected to the first circuit board 324, the second circuit board 334 and the third circuit board 344, and the electric wires can pass through the openings of the second supporting posts 3022 to complete the circuit configuration of the first circuit board 324, the second circuit board 334 and the third circuit board 344. Since the wires can be accommodated in the axis inside the switching cylinder 351, when the switching cylinder 351 rotates, the wires will not rotate along with the switching cylinder 351, and the wires will not be twisted and damaged due to over-rotation.

According to the operation, a user can control different sensing modules to be exposed out of the opening of the shell according to the requirement so as to select the proper moving resolution. The switching module in the mouse acts by matching a mechanical structure with a simple detection element and a control unit, so the mouse has the advantages of simple structure and low cost. In addition, the first sensing module, the second sensing module and the third sensing module are respectively different types of sensing modules, so that the first sensing module, the second sensing module and the third sensing module are respectively suitable for different types of working surfaces, and therefore, besides the moving resolution, a user can select a suitable sensing module according to the requirement, and the mouse can run on the suitable working surface. In other words, the mouse of the invention not only can change the moving resolution, but also can run on various working surfaces.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, so that other equivalent changes and modifications without departing from the spirit of the present invention are intended to be included within the scope of the appended claims.
