Abstract

PROBLEM TO BE SOLVED: To reduce the number of components and to facilitate the assembling work by forming left and right buttons by making a cut in the front part of an upper case itself to divide the front part into lift and right parts and allowing the respective left and right buttons to freely and flexibly return in the direction of pressing or separation. SOLUTION: An upper case 11 is provided with an elliptical window 11a exposing the elliptically swelling part of a middle case, and a notch 11b reaching the window 11a is formed at a central part its front part in a longitudinal direction while dividing it to the left and right parts to form a left button 13a and a right button 13b shown by half-tone dot meshing. Then, the case 11 united integrally with both the buttons 13a and 13b in this way is fixed to the middle case at its rear part with screws 16. Then, the buttons 13a and 13b can freely and flexibly return in the direction of pressing or separation with a screw stopping part as a support. Furthermore, armatures 15 brought into contact with switches are respectively provided on the rear faces of the both buttons 13a and 13b.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a mouse used as an input device for a computer or the like.

[0002]

2. Description of the Related Art A mouse has been widely known as a pointing device for inputting a moving amount of a cursor on a display screen of an information processing apparatus such as a computer. The mouse moves the built-in ball when the operator moves on a plane, and thereby the x of the ball
As a result of outputting data indicating the amount of rotation in the axial direction and the y-axis direction to a computer or the like, the cursor on the display screen moves in the moving direction of the mouse based on the data. Then, when the cursor points to a window desired by the operator, the window can be opened by clicking a click button.

[0003]

By the way, in the conventional mouse, since the click buttons constituting the mouse are independently provided as a left button and a right button, respectively, the button parts and the respective urging means are provided. Is required, the number of parts is increased, and the operation of assembling buttons in a mouse manufacturing process has to be performed separately.

The present invention has been made to solve the above problems, and has as its object to provide a mouse capable of reducing the number of parts and simplifying an assembling operation.

[0005]

In order to solve the above-mentioned problems, a mouse according to the present invention has a left button and a right button for outputting an operation signal by an operator's pressing operation to a computer or the like, which are cut into a front portion of the upper case itself. And divided into left and right, and each of them can be elastically returned in the pressing and separating direction.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a mouse 10 according to the invention.
FIG. 2 is a cross-sectional view of a state where the upper case 11 is assembled to the middle case 12.

The mouse 10 forms an elliptical housing with a bottom case, a middle case 12 and an upper case 11 (not shown). And a rotatable ball, a part of which faces the outside of the case, a rotation amount detection unit that detects the amount of rotation of the ball in the x-axis direction and the y-axis direction, and outputs the data to a computer.

The upper case 11 includes a middle case 12
An elliptical window 11a for exposing the elliptical bulge portion 12a of the elliptical window 11a.
The notch 11b leading to a is formed and divided into left and right,
A left button 13a and a right button 13b shown by hatching are configured. That is, the left button 13a and the right button 13b
Is integrated with the upper case 11, and there is no need to separately prepare a button component. The upper case 11 integrated with the buttons 13a and 13b as described above.
Is fixed to the middle case 12 by a screw 16 at a rear portion thereof. Therefore, the left button 13a and the right button 13b can be elastically returned in the pressing and separating direction with the screw stop as a fulcrum. In addition, these two buttons 13a, 13
A contact piece 15 that contacts the switch 14 is provided on the back surface of each of the switches b.

In order to assemble the buttons 13a and 13b, it is only necessary to fix the rear portion of the upper case 11 to the middle case 12 with screws 16. Now both buttons 13
Since a and 13b are attached to the case,
Assembly work becomes easy. Further, a button component is not required, and the number of components can be reduced.

[0010]

As described above, according to the mouse of the present invention, the front part of the upper case itself is divided into left and right parts to form left and right buttons, so that the button parts themselves are unnecessary, and the number of parts is reduced. Be reduced. Further, by fixing the upper case itself, both buttons are assembled, so that the assembling work is also facilitated.
Furthermore, since both buttons can be elastically returned in the pressing / separating direction, there is no need to separately provide urging means for the buttons.

Claims (1)

[Claims] 1. A mouse having a left button and a right button for outputting an operation signal by an operator's pressing operation to a computer or the like, the left button and the right button are divided into right and left by making a cut in a front portion of an upper case itself. The mouse is characterized in that it can be elastically returned in the pressing and separating directions.
