Key moving type character input keyboard

Abstract

The invention discloses a key moving type character input keyboard which comprises a keyboard fixing frame, one moving plane or a plurality of moving planes, a plurality of keys and a key circuit. The key circuit is in serial connection with a slide rheostat and a multi-le-contact switch. The moving plane or the moving planes are installed on the keyboard fixing frame through a slide rail, and the moving plane can slide to a plurality of preset positions on the slide rail. When the moving plane slides to each preset position, the moving plate can drive the slide rheostat or the multiple-contact switch connected with the moving plane to send corresponding signals to a control chip. Two signals triggered by one key pressed downwards are sent to the control chip. The control chip can judge required input characters according to a preset procedure and the two signals. The key moving type character input keyboard enables the keys to move, the keys can be pushed to move up and down by the palm or fingers, and each key corresponds to three corresponding positions of the upper position, the middle position and the lower position. Thus, three different characters can be arranged and distributed to share one key, a moving range of the hands is reduced, the character input efficiency is improved, and hand fatigue is reduced.

Description

technical field [0001] The invention relates to a keyboard device capable of inputting letters, symbols and the like. Background technique [0002] Due to the development of technology, various smart devices and products (computers, mobile phones, numerical control equipment, etc.) are widely used in real life. These smart devices and products need to input instructions through reliable and efficient human-computer interaction devices. The keyboard, invented in the 17th century, has always occupied an irreplaceable position in computer input devices because of its reliability and high efficiency. Especially since the invention of computer in the 1940s, keyboard has been widely used as a kind of main computer input device. However, the main disadvantages of the current keyboards are: the number of keys is large, which affects the input efficiency, and the volume cannot be reduced. [0003] Taking the current 101 and 104 standard computer keyboards as an example, the keyboa...
