Mouse having composite switch device

## Abstract

The present invention relates to a mouse having a composite switch device. The composite switch device includes a push button, a multi-stage sliding switch unit and a tactile switch unit. By moving a single push button to different positions, the use modes of the mouse will be switched.

## Background
FIELD OF THE INVENTION
The present invention relates to a mouse, and more particularly to a mouse having a composite switch device.
BACKGROUND OF THE INVENTION
Due to the amazing power of personal computers, personal computers are developed to have various functions. Typically, the mouse is used as a cursor control device for controlling cursor movement on the computer monitor. Recently, the mouse is used as various input control device under execution of different software.
For complying with diversified functions of the personal computer, in addition to the conventional cursor control function, the mouse may be used as for example a controller for presentation control and/or multimedia (e.g. music or movies) control. For example, during the process of making a presentation, the mouse is usually used as a remote controller for controlling playback of presentation slides. When the personal computer is used as a multimedia tool, the mouse is operated to control playback of music or movies.
Depending on the applications of the personal computer, the functions of identical buttons of the mouse are varied. For example, in a case that the mouse is a cursor control device for the personal computer, a specified item on the option menu of the computer monitor is selected by operating the specified buttons of the mouse. During the process of making a presentation, a “Page Up” function is executed to have the slide backward to the previous page or a “Page Down” function is executed to have the slide forward to the next page by operating the specified click buttons. In the multimedia operating mode, the specified buttons of the mouse are actuated to provide volume up and volume down functions.
For switching the functions of identical buttons when the mouse is operated in different use modes, two approaches are commonly provided. In the first approach, a graphic-based user interface is created under execution of a switching program. Via the user interface, a desired use mode is selected by the user. In the second approach, multiple switch devices are arranged on the mouse. These switch devices are activated to execute corresponding functions.
As previously described, the desired use mode is selected after the user interface is created. For a purpose of changing the use mode, the user interface should be created again to select another use mode. The first approach, however, is not user-friendly. The arrangement of multiple switch devices may avoid switching the use modes under execution of the switching program. However, too many switch devices will increase the volume and the cost of the mouse.
In views of the above-described disadvantages resulted from the prior art, the applicant keeps on carving unflaggingly to develop an improved mouse according to the present invention through wholehearted experience and research.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 is a schematic exploded view of a mouse having a composite switch device according to a preferred embodiment of the present invention. The mouse of FIG. 1 principally includes a main body 1, an upper cover 2, a fixing ring-member 3, a push button 4, a circuit board 5, a multi-stage sliding switch unit 6 and a tactile switch unit 7.
The main body 1 has an elongated concave portion 12 in the upper surface 11 thereof. A stopping element 13 is arranged at a short edge of the elongated concave portion 12. The upper surface 11 of the main body 1 is covered by the upper cover 2. The upper cover 2 has a perforation 21 therein. The push button 4 is received within the elongated concave portion 12 and movable along the elongated concave portion 12 in the direction indicated as the arrow A. The fixing ring-member 3 is arranged between the upper cover 2 and the push button 4 for facilitating fixing the push button 4 in the elongated concave portion 12. In addition, the push button 4 has a tongue depressor 41 extended from an end thereof.
The assembled view of the mouse is schematically illustrated in FIG. 2. As shown in FIG. 2, the push button 4 is protruded from the outer surface of the upper cover 2 such that the push button 4 may be manipulated by a user. By moving the push button 4 in the direction indicated as the arrow A, the mouse may be operated in a specified use mode as required.
FIG. 3A is a schematic perspective view illustrating the combination of the push button 4, the multi-stage sliding switch unit 6 and the tactile switch unit 7 of the mouse in a first use mode. As shown in FIG. 3A, the push button 4 includes a tongue depressor 41, a clamp part 42 and a touch part 43. The multi-stage sliding switch unit 6 and the tactile switch unit 7 are disposed on the circuit board 5. An exemplary multi-stage sliding switch unit 6 is a three-stage sliding switch unit. The three-stage sliding switch unit 6 includes a gliding arm 61. The tactile switch unit 7 includes a triggering part 71. Referring to FIG. 3B, the location of the push button 4 relative to the stopping element 13 of the main body 1 of the mouse in the first use mode is shown.
Hereinafter, the operations of the three-stage sliding switch unit 6 will be illustrated with reference to FIG. 3A. Along the direction indicated as the arrow A (FIG. 2), the gliding arm 61 may be moved to a first position P1, a second position P2 or a third position P3. Depending on the positions of the gliding arm 61, the use modes of the mouse are varied. For example, in a case that the gliding arm 61 is adjusted to the first position P1, the mouse is operated in a presentation mode. In another case that the gliding arm 61 is adjusted to the second position P2, the mouse is operated in a cursor control mode (i.e. as the general mouse). In a further case that the gliding arm 61 is adjusted to the second position P3, the mouse is operated in a multimedia mode.
Referring to FIGS. 3A and 3B again, the relative locations between the push button 4 and the gliding arm 61 when the mouse is operated in a presentation mode are schematically illustrated. Since the gliding arm 61 of the three-stage sliding switch unit 6 is clamped by the clamp part 42 of the push button 4, the position of the gliding arm 61 is adjusted with movement of the push button 4. For example, as shown in FIGS. 3A and 3B, the gliding arm 61 is adjusted to the first position P1, so that the mouse is operated in a presentation mode. In this presentation mode, the tactile switch unit 7 is activated to control playback of presentation slides. When the gliding arm 61 is located at the first position P1, the tongue depressor 41 of the push button 4 is separated from the stopping element 13 and the touch part 43 of the push button 4 is aligned with the triggering part 71 of the tactile switch unit 7. In a case that the gliding arm 61 is located at the first position P1 and the mouse is operated in the presentation mode, the triggering part 71 of the tactile switch unit 7 is triggered to generate to a presentation control signal when touch part 43 of the push button 4 is pressed down. In response to the presentation control signal, for example, a “Page Up” function is executed to have the slide backward to the previous page or a “Page Down” function is executed to have the slide forward to the next page.
Referring to FIGS. 4A and 4B again, the relative locations between the push button 4 and the gliding arm 61 when the mouse is operated in a cursor control mode (i.e. as the general mouse) are schematically illustrated. With movement of the push button 4, the gliding arm 61 is adjusted to the second position P2, so that the mouse is operated in the cursor control mode. When the gliding arm 61 is located at the second position P2, the tongue depressor 41 of the push button 4 lies on the stopping element 13. Meanwhile, the touch part 43 of the push button 4 is no longer aligned with the triggering part 71 of the tactile switch unit 7. In this general mouse mode, the function of triggering the tactile switch unit 7 may be exempted. Even if the push button 4 is pressed down, the tongue depressor 41 of the push button 4 is stopped by the stopping element 13 from advancing downwardly and the touch part 43 of the push button 4 is no longer aligned with the triggering part 71 of the tactile switch unit 7. Under this circumstance, if the push button 4 is accidentally pressed down, no generation of an unanticipated control signal is rendered because the tactile switch unit 7 is not triggered.
Moreover, the function of triggering the tactile switch unit 7 may be exempted when the mouse is operated in the multimedia mode. Please refer to FIGS. 4A and 4B. With movement of the push button 4, the gliding arm 61 is adjusted to the third position P3, so that the mouse is operated in the multimedia mode. When the gliding arm 61 is located at the third position P3, the tongue depressor 41 of the push button 4 still lies on the stopping element 13 and the touch part 43 of the push button 4 is no longer aligned with the triggering part 71 of the tactile switch unit 7. Likewise, if the push button 4 is accidentally pressed down, no generation of an unanticipated control signal is rendered because the tactile switch unit 7 is not triggered.
From the above description, due to the specified design of the complex switch device according to the present invention, the use modes of the mouse may be switched by moving a single push button to different positions. The functions of triggering the tactile switch unit in some use modes are exempted, so that the mouse will not be suffered from an erroneous operation. Since no user interface should be created under execution of the switching program, the switching method of the mouse is more user-friendly. Moreover, since the mouse of the present invention has reduced number of push buttons, the volume and the cost thereof is decreased.
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
