DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse for a computer, and more particularly, to an ergonomic design of a mouse for inputting a control signal to a signal processing device such as a computer to improve the operability of the mouse. The present invention relates to a computer mouse which is improved and can be used without having to hold the mouse by a mouse fixing.

[0002]

2. Related Art In general, a computer mouse has a trackball made of, for example, a steel ball rotatably provided on a bottom surface of a mouse main body, and X and Y-axis coordinate moving mechanisms orthogonal to each other inside the mouse main body. In addition, the cursor is provided in contact with the trackball, and the cursor position on the computer screen is moved to a desired coordinate by an X-axis and Y-axis coordinate movement mechanism that responds to the rotation of the trackball. Further, a click switch is provided on the upper surface of the mouse body. For example, in a state where a desired cursor position is obtained by moving the mouse, a required click switch is operated to input the cursor position as control data to the computer. Like that.

[0003] However, the conventional mouse described above has a problem that a trackball is rotated on the mouse pad when the mouse is used, so that a space for installing the mouse pad is indispensable. In addition, there is a problem that foreign matter accumulated in the mouse pad enters the X and Y axis coordinate moving mechanism through the trackball and hinders smooth cursor movement.

[0004] A proposal for solving such a problem is presented in, for example, Korean Utility Model Registration Application No. 92-27022. As shown in FIGS. 1 (a) and 1 (b), a mouse 30 according to this proposal has a hexahedron-shaped mouse body 32 which is generally long in the vertical direction. A trackball 34 for moving is provided, and a first and a second for inputting control data such as cursor coordinates are provided on one upper side of the back of the mouse main body 32.
Click switches 36a and 36b are provided adjacent to each other in the vertical direction of the mouse body.

Further, the mouse 30 according to the above proposal is used in a state of being fixed vertically to a keyboard or a table by a double-sided tape 38 provided at a lower portion of a mouse main body 32, and does not require a mouse pad. Therefore, no foreign substances enter the mouse body from the mouse pad. However, the mouse 30 has a drawback that it is difficult for a user to grip the mouse main body since the mouse main body is generally a hexahedral shape having corners. In addition, since the position and arrangement of the first and second click switches are inappropriate, the user can simply click on the base of the index finger or the middle finger to simply grasp the mouse body. There was a problem that the switch was activated and caused an erroneous operation.

Further, the conventional mouse 30 is used by fixing it to a fixed object such as a keyboard or a table as described above, and there is a restriction that the mouse 30 must be used while being held by the mouse fixed object. Yes, and there is a problem that the mouse cannot be used at a position separated from the mouse fixed object.
