Novel computer keyboard

Abstract

The invention discloses a novel computer keyboard, relating to an improvement on a key layout, marks, definitions, codes and circuit diagrams of a computer keyboard. The novel computer keyboard is characterized in that: key mappings of the whole keyboard consist of 89 keys in 6 lines and 16 rows form top to bottom, and the whole keyboard is called as 89 type keyboard; and the key mappings are symmetrically arranged left and right in a rank matrix positive position way, and are divided into three big zones consisting of a functional key zone, a control key zone and a character key zone. The control keys are arranged in a shape of a Chinese character 'ao' (meaning concave); the character keys are arranged in a shape of a Chinese character 'tu' (meaning convex) which rolls over by 90 degrees left and right in an opposite way; and the digital keys are arranged in an I shape in the center of the keyboard. As the novel layout is adopted, circuit diagrams are optimized and novel functions like composite symbols, mathematical formulas and text control are additionally arranged, therefore, not only the keyboard size is reduced and the product production technique and cost are reduced, but also the functions are improved, thereby greatly improving the keyboard application. The novel computer keyboard is applicable for all computers operated through keyboards.

The main key area has a scattered and misplaced layout, which has the following disadvantages: 1. The layout of the main key area is to the left, which will affect the sitting posture and physical and mental health after long-term use; 2. The keys are in a misplaced layout, which is not only easy to press the wrong key, but also easy to cause finger fatigue 3. The key characters are arranged in disorder, which increases the time for beginners to train fingering; 4. The common text symbols are incomplete, which affects the editing of manuscripts; 5. There is no mathematical formula function and cannot handle mathematical, physical and chemical formulas; 6. Many languages ​​​​such as Latin , Cyrillic and other letters often have modifier symbols, and the keyboard lacks the function of directly inputting modifier symbols. 7. Languages ​​such as English and Chinese and Arabic belong to two writing languages ​​in different directions, and sometimes appear mixed in a document , the keyboard cannot directly control the order of the text and the forward and reverse directions of the word order, and cannot meet the mixed editing requirements of the forward and reverse bidirectional languages ​​in the document. 8. The secondary keyboard (commonly known as the numeric keypad) is located on the right side of the keyboard, which is not suitable for habit left-handed person
