Problems solved by technology

However, due to the realization of the function and lighting of the key pairs of the keyboard, corresponding light emitters need to be provided, and the number of keys on the keyboard is relatively large.
In this way, the number of light emitters required to be set is relatively large, resulting in a more complicated structure of the keyboard and increasing the manufacturing cost

Abstract

The invention discloses a key and a keyboard. The key comprises: a light emitter; a light receiver, wherein the light receiver and the light emitter are arranged at an interval; a base, wherein a light transmitting part and a reflecting part are formed on the base, the light transmitting part and the reflecting part are arranged corresponding to the light emitter, and the reflecting part can transmit a light signal emitted by the light emitter to the light receiver; and a pressing mechanism, wherein the pressing mechanism comprises a pressing assembly and a light blocking piece, the pressing assembly is movably arranged on the base and covers the light transmitting part, the light transmitting part can transmit a light signal emitted by the light emitter to the pressing mechanism, the light blocking piece is connected to the pressing assembly, and when the pressing assembly is driven, the light blocking piece can conduct or block a light path between the reflecting part and the light receiver. According to the technical scheme, the manufacturing cost of the keyboard is reduced.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a key and a keyboard using the key. Background technique [0002] At present, the key of the keyboard in the related art can not only realize the function of the key through the optical path, but also realize the illumination of the key through the optical path. Specifically, when the key is pressed, the function of the key is realized through the conduction or blocking of the optical path between the light transmitter of the reflection part and the light receiver of the reflection part, and the connection of the light path is realized through the conduction of the light path of the second light transmitter. Illumination of the keys. However, since the realization of the function and illumination of the key pairs of the keyboard requires corresponding installation of light emitters, and the number of keys on the keyboard is relatively large. In this way, the number of light e...
