[0003]

A keyboard used as an input device of a computer is provided with keys in which alphabets and letters are given and numeric keys called numeric keys. However, miniaturization of a notebook computer is required. Therefore, the numeric keypad cannot be arranged. In such a notebook computer, when the Roman character input is selected as the input mode, the number input operation can be performed as it is because there is a numeric key in place of the numeric keypad, but when the kana input mode is selected. Has a problem in that it is not possible to perform a numeric input operation unless it is converted to Roman alphabet input.

[0004] The present invention aims to provide a computer input device that solves the above problem.

[0005]

Further, the system is configured to display the battery voltage and the like on the function display device 9 by the control operation of the system circuit 10.

In such a configuration, the present invention is such that the mouse pad 3 used as an operation means for moving a normal mouse pointer can be used as a numeric keypad. For example, when the plug of the external mouse 11 is inserted into the input jack 7 for the mouse, the function is changed to a state in which the mouse pad 3 is used as a numeric keypad by the switching control operation of the system circuit 10. Figure
Reference numeral 2 denotes a state in which the mouse pad 3 is changed to a state in which the mouse pad 3 is used as a numeric keypad by such switching, and a number can be input by operating the numeric keypad.

When the external mouse 11 is connected to the main body 1, the mouse pad 3 is switched to a state in which the mouse pad 3 is used as a numeric keypad. You can also By operating one or both of the click pad switches 4, the mouse pad 3 can be switched to a state where it is used as a numeric keypad.

The mouse pad 3 is provided with a display indicating the function of the button as shown in FIG. 2. If the display is performed electrically, the mouse pad 3 can operate as a numeric keypad. It can be displayed that there is. Further, the display device 6 may be configured to display whether the mouse pad 3 is in a function state of moving a mouse pointer or in a state of functioning as a numeric keypad. As the display method, for example, the display can be performed by changing the shape of the mouse pointer.

In the above description, the input function status of the mouse pad is displayed on the display device 6.
, An input function display device may be provided, and the input function state of the mouse pad may be displayed on the display device. Further, the input function status of the mouse pad may be displayed on the function display device 9 provided to display the voltage of the battery and the like.

Further, an input confirmation sound can be emitted when a pressing input operation is performed in a state where the mouse pad 3 is used as a numeric keypad using an audio device provided in the computer. .

When the input mode of the keyboard 2 is changed to the kana input state, the mouse pad 3 can be switched to a state used as a numeric keypad.

In the above-described embodiment, the mouse pad is used as a numeric keypad. However, the mouse pad may be used as a handwriting input device used for kanji search and the like.

[0016]

According to the present invention, a mouse pad arranged close to a keyboard can be used as an input device for a numeric keypad, so that the present invention is applied to a computer in which a numeric keypad cannot be arranged like a notebook computer. In such a case, a very large effect is achieved.

Further, according to the present invention, when an external mouse is connected to the main body, the mouse pad can be used as a ten-key input device, so that the operability is excellent.

Since the input function of the mouse pad is switched by the pad switch for clicking, the present invention has an advantage that a special switch is not required and the configuration is simplified.

Further, according to the present invention, since the input function status of the mouse pad is displayed on the display device provided on the lid, the user can easily confirm the input function status. Further, according to the present invention, the shape of the mouse pointer displayed on the display device provided on the lid is changed, so that the user can more easily confirm the change.

In the present invention, the input function status of the mouse pad is displayed by using the display device for displaying the status of the battery, so that the user can easily confirm the input function status.

Further, according to the present invention, when a pressing input operation is performed, a confirmation sound is emitted, so that it is possible to recognize that the input has been performed.

The present invention is excellent in operability because the mouse pad can be switched to the use of the numeric keypad in the kana input state.

Further, according to the present invention, since the mouse pad can be used as a handwriting input, a desired kanji can be easily searched, for example, when the mouse pad is used for performing a kanji search.
