Abstract

A keyboard includes an elastic part, a light emitter, a light receiver, a pressing part and a keycap. The elastic part is arranged above the lower casing and has a top surface. When the top surface is subjected to a force toward the lower casing, the force required to push the top surface is negatively correlated with the distance from the top surface to the lower casing during the path of the top surface moving from the first position to the second position, In the path of the top surface moving from the second position to the third position, the force required to push the top surface is positively correlated with the distance from the top surface to the lower casing. The light emitter and the light receiver are arranged above the elastic member. The pressing part is arranged above the elastic part and is movable relative to the lower casing. The pressing part has a first inner wall, and the first inner wall is located between the light path of the light emitter and the light receiver and has an opening. The width of the opening is graduated. The key cap is arranged above the pressing part.

Description

technical field [0001] The content of the present invention relates to a keyboard. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters or numbers. Not only that, all the consumer electronic products that are in contact with in daily life are provided with a keyboard as an input device for easy operation. Regarding the working mechanism of the keyboard, when the user presses the keyboard key, the electrical switch inside the key can be triggered, so that the key can output a signal representing the pressing action. For example, when the button is not pressed, the button will output a low-level signal, and when the button is pressed, the button can output a high-level signal through an electrical switch. [0003] In this regard, for the signal output by the key, it can only be used to determine whether the key is pressed, but cannot determine the degree o...
