Abstract

The invention relates to a keyboard with a mode switching function, which comprises at least one key, a pressure detection circuit, a light-emitting module, a mode switching program and a control unit. The mode switching program is used for starting up the pressure detection circuit and the light-emitting module, so that the keyboard is in a pressure sensing light-emitting mode. The pressure detection circuit detects the size of pressure of touching and pressing keys to generate a touch-pressure strength voltage, and the control unit allows the light-emitting module to generate a first light beam or second light beam according to the touch-pressure strength voltage. In the invention, the modes of the keyboard can be changed by users according to different situations so as to facilitate operation.

Description

technical field [0001] The invention relates to an input device, in particular to a keyboard with a mode switching function. Background technique [0002] Generally speaking, computer peripheral input devices include a mouse, a keyboard, and a trackball. The keyboard can directly input characters and symbols into the computer, so the keyboard is highly valued by users and input device manufacturers. Next, the structure and functions of known keyboards are explained, please refer to figure 1 , which is a schematic diagram of the appearance structure of a known keyboard. The surface of the known keyboard 1 has a plurality of keys, and these keys are classified into general keys 10, number keys 11, and function keys 12, etc. These keys are used by users to press with fingers to generate corresponding signals to the computer, so that the computer Execute the function of the pressed key, for example, the general key 10 is used to input symbols such as English letters, the numbe...
