Computer data input apparatus

Abstract

The invention discloses a computer data input apparatus, and belongs to the technical field of keyboards. The apparatus comprises a keyboard; a protective plate frame is arranged at the lower end of the keyboard; limiting slots are formed in the protective plate frame; a protective plate is arranged on one side of the protective plate frame; support legs are arranged on the lower surface of the protective plate; one end of each support leg is fixed to the lower surface of the protective plate by adhesion; a rotary rod is arranged at the other end of each support leg; each rotary rod runs through the surface of one end of each support leg; and limiting wheels are arranged at two ends of each rotary rod. The design adopts a mode of cooperation of the protective plate frame, the protective plate, the support legs, the rotary rods, the limiting wheels and the limiting slots; a user puts the wrist above the protective plate during typing, so that the fatigue of the user in supporting both hands for long-time typing is reduced and the typing comfort of the user is improved; and when the user needs to move the wrist, the support legs on the lower surface of the protective plate and the rotary rods enable the limiting wheels to move in the limiting slots, so that the user is prevented from raising the wrist when moving the wrist.

Description

technical field [0001] The invention belongs to the technical field of keyboards, and in particular relates to a data input device for a computer. Background technique [0002] The keyboard is the most commonly used and most important input device, through which English letters, numbers, punctuation marks, etc. can be input into the computer, so as to issue commands and input data to the computer. During the use of the existing keyboard, when the user inputs data to the computer, the user's hands need to be placed above the keyboard, and the user erects his hands for a long time, which increases the fatigue of the user's typing. At the same time, when the keyboard is placed on the desktop, the user's fingers Different lengths lead to different moving distances when users touch the keyboard, which increases the difficulty of typing for users with shorter fingers. Therefore, we propose a data input device for computers. Contents of the invention [0003] The purpose of the ...
