Ten-key collection keyboard

The invention discloses a ten-key collection keyboard and belongs to the field of computer accessory equipment. The keyboard comprises ten keys. The keys are embedded onto a keyboard shell. A keyboard circuit and a code circuit are located in the keyboard shell. Communication interfaces are located on the keyboard shell and are connected with the code circuit. The ten keys of the keyboard correspond to ten fingers of a person respectively. Each key is of an oblong structure, the width of the upper surface of each key ranges from 1.3 centimeters to 2.5 centimeters, and the length of each key is at least twice that of the width of the key. In the using process, the person naturally puts the ten fingers on the ten keys of the keyboard and does not need to move the fingers when hitting the keys to carry out input, so long-term operation on the keyboard will not result in fatigue of the fingers and the wrists, possible wrong hitting in the touch typing and key finding process can be avoided, and the keystroke speed is increased. The ten-key collection keyboard is compact in structure and convenient to carry, keyboard operation under certain key position coding rules can be achieved, and the ten-key collection keyboard can be popularized and especially provides a computer input device for Braille users and special control industries.
