 Background technique

 Say

 First, there are some differences in the layout of the buttons between the desktop computer keyboard and the notebook computer keyboard. The desktop computer generally uses the 104 keyboard. In terms of layout, the keyboard is divided into four areas, which are the typing letter keypad, the editing control keypad, the sub keypad and the function keypad. The layout is too scattered, overall. Large size, the following deficiencies:

1. When switching between different keypads, the movement of fingers and hands is large, which is easy to cause fatigue and keystroke errors.

2. The overall size is large, which is not conducive to the use of table tops and affects other functions of the table top.

3. When the keyboard is placed in the habit or the right position is restricted, when the body is typing on the screen, the two hands cannot be symmetrical with the left and right symmetry planes of the body, but are biased to the left side of the body. This phenomenon does not match. Ergonomic requirements. It is not good for your health, and it is not conducive to improving operational efficiency. Second, for the notebook computer, due to its size limitation, the keyboard adopts a centralized layout. Compared with the desktop computer, the typing keypad and the function keypad do not change much, but are concentrated, but the editing keypad is ranked. There are certain changes. There are also differences in the keyboard between different brands of notebook computers. The notebook computer keyboard generally cancels the independent sub-keypad, and sets its digital and symbol key functions in the multi-function function of some character keys in the typing area. On the whole, the notebook computer keyboard is limited by the small size, the button setting is somewhat far-fetched, it seems somewhat disordered, and the operation is naturally inconvenient. This is A recognized fact. Because there are some differences in the layout between the keyboard of the notebook and the desktop computer, people are uncomfortable with the keyboard when they use the notebook computer and the desktop computer interchangeably, which affects people's operation and use. Third, the notebook keyboard and desktop computer keyboard have the following deficiencies:

1. The space bar generally occupies 5 to 7 common key positions in the center of the bottom row, so the space bar becomes the most "luxury" button, which is a waste of resources, and has the following disadvantages:

1), increasing the degree of edge of other buttons, is not conducive to operation, and is not conducive to reducing the size of the keyboard.

2) The function of using the thumb is not fully exerted. The cooperation between the thumb and any of the other four fingers is more flexible than the fit of any two fingers between the four fingers. Because the space bar takes up too much position, it is crowded. The position of the button discharge that is more suitable for the thumb operation affects the effective thumb usage rate, that is, affects the efficiency of the human-machine system engineering.

2), Backspace key, is also a commonly used key when typing, not in the range of easy finger control, it is not convenient to operate.

3), Shift key (upper key) is also a common key, placed on both sides of the typing area by the control of the little finger and then cooperate with other fingers to complete the operation, we all know that the little finger is the least strong of all the fingers, and the coordination with other fingers is not flexible enough Therefore, the setting of the Shift key does not meet the ergonomic requirements, and the operation is not only easy to cause fatigue of the little finger, but also affects the operation efficiency.

4) The overall combination of the key areas in the typing area is not reasonable enough. The number of left-hand control keys is small, and the right-hand control keys are more. Therefore, the right-hand operation range is larger, and the finger movement span is larger, which not only causes the right hand fatigue, but also affects the overall typing efficiency.

Summary of the invention The purpose of the utility model is to realize the uniform arrangement of the keys of the notebook computer keyboard and the desktop computer keyboard, which is convenient for interchangeability, is more suitable for people's operating habits, maximizes the human-machine function, improves work efficiency, and reduces the overall keyboard. size.
