Abstract

A keyboard with cursor device is composed of a cursor direction input unit for user to input the displacement of cursor, a function enabling key for user to control the function corresponding to the position of cursor, and the cursor direction input unit and function enabling key arranged in left and right regions of keyboard for user to use left and right hands.

Description

keyboard with cursor device

The utility model relates to a keyboard with a cursor device.

General pointing devices, such as mouse, joystick, digital tablet, etc., in addition to the cursor direction input function, also have a number of function enable keys. When the cursor moves to a specific position, these function enable keys allow the user to input control Instructions that instruct application software in a computer to perform specific tasks. For example, the buttons on the mouse can select the application software in the window; the buttons on the handle of the joystick can instruct the characters in the game to jump; the input pen tip of the digital board can position the objects in the CAD software drawing.

Most of the above-mentioned traditional pointing devices are difficult to be combined with the keyboard input device. As a result, in addition to purchasing the keyboard, the general user must also purchase an additional pointing input device, which is independently installed on the serial port of the host.

Once the connection between the input device and the computer is in a "wireless" manner, each of the "wireless keyboard" and the "wireless pointer device" needs a wireless communication port, so the cost of the entire device is relatively high.

Therefore, in order to save the space occupied by the input device and the number of ports connected to the host, a small number of keyboards are equipped with second-generation pointer input devices, such as track balls, touch coordinate pads, or pointsticks. , to replace the traditional pointer input device; so that the same keyboard device can simultaneously have the function of pointer direction input.

But up to now, the keyboard that is provided with the second-generation indicator input device all is that the cursor direction input device and the function enabling key are concentrated on the same adjacent area of the keyboard, that is, they are either placed in the center of the bottom edge of the keyboard together, or Set on one side of the keyboard.

However, one of the purposes of setting the second-generation indicator input device is to save keyboard space, so the usable keyboard space is relatively small. The second-generation indicator input devices currently available on the market are only suitable for one-handed operation. When operating the cursor direction input key and the function enable key at the same time, the user may experience unsmooth operation because the thumb and index finger apply force at the same time. For example, when the thumb moves the cursor to the position and the index finger simultaneously presses the function activation key to select, it often causes unnecessary movement of the thumb tip, which causes the cursor to shift, and affects the correct positioning of the cursor.

The purpose of the present invention is to provide a keyboard structure, the user can use the left and right hands to operate the cursor direction input function and the function enabling key respectively, and the operations of the left and right hands will not interfere with each other.

The purpose of this utility model is achieved by providing a keyboard with a cursor device, which includes: a cursor direction input device for a user to manipulate to input the displacement of the cursor; a function enabling key for The user controls to enable the function corresponding to the position of the cursor; wherein, the cursor direction input device and the function enabling key are respectively arranged on the left and right sides of the keyboard for the user to use the left and right hands to operate respectively .

The advantage of the keyboard structure of the utility model is that when the user holds the keyboard with both hands, he can operate the cursor direction input function and the function enabling key without interfering with each other.

Below, will describe the utility model in detail in conjunction with accompanying drawing, in the accompanying drawing:

Fig. 1 is the keyboard of the present utility model;

FIG. 2 shows a schematic diagram of a user operating the keyboard of the present invention.

As shown in Figure 1, the keyboard of the present utility model is mainly divided into three major areas, the input key of conventional keyboard is arranged in the central area, a cursor direction input device button 15 is arranged in the right area, and a function enabling key is arranged in the left area. It contains keys 11 , 13 .

The cursor direction input device 15 is manipulated by a user to input the displacement of the cursor. The function enabling keys 11 and 13 are manipulated by the user to enable the function corresponding to the position of the cursor. The cursor direction input device 15 and the function enabling keys 11 and 13 are respectively arranged on a right side and a left side area of the keyboard for the user to use right and left hands to operate respectively. The cursor direction input device can be a little joystick, or a trackball.

In addition to the location arrangement of the cursor direction input key and the function enable key, grooves 17 are provided on the front edges of the left and right sides of the keyboard for the index finger of the left or right hand to be placed there, which is convenient for the user to hold the keyboard. In addition, an arc-shaped depression 19 is designed on the upper panel of the keyboard close to the left and right side edges for attachment to the inner edges of the left and right thumb roots. The above structures all contribute to the comfort of the user holding the keyboard, as shown in FIG. 2 .
