Embodiment Construction

[0011] A multi-layout keyboard, including 26 English letter keys, 26 English letter keys on the keyboard, each key has two key output terminals, one of which is to express a certain letter of 26 letters arranged in the order of A to Z The key output terminal, the other output terminal is a certain letter key output terminal that expresses 26 letters arranged according to the required order (for example, QWERTY form or other required forms); the above two key output terminals are respectively connected with a two-way 26-bit multi-way The two-way input terminals 1 and 2 of the multiplexer 3 (also known as MUX) are connected, the two-way 26-bit multiplexer has an output terminal 4 connected to the input terminal of the subsequent circuit, and the two-way 26-bit multiplexer Connect with high and low level selection switch 5 (S1). The user selects the working mode of the keyboard (switching between different keyboard layouts) by selecting the switch S1. When S1 is connected to low...

Description

Technical field: [0001] The invention relates to a computer keyboard. Background technique: [0002] In 1874, Christopher Sholes invented the QWERTY keyboard in order to slow down the typing speed and separate the commonly used letters to reduce the incidence of extrusion failures between the linkage rods when the typewriter was typing. . In 1932, August Dvorak (August Dvorak) invented the Dvorak keyboard, hoping to rearrange the keys to increase typing speed after it was no longer necessary to avoid the extrusion of the linkage rod. But people have become accustomed to QWERTY keyboards, and Dvorak keyboards cannot be mass-produced. Later, people also invented a variety of keyboards with different sorting forms, but they were not mass-produced due to people's usage habits. Invention content: [0003] The object of the present invention is to provide a multi-layout keyboard with a reasonable structure, which can not only be sorted and input according to customary letters...
