Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] In order to describe the principle of the key-value circuit of the present invention, figure 1 A simple example is given, which means that n input lines (I / O ports) can be used to represent up to 2 n – 1 key-value. For n input lines, all states have a total of 2 n One, where n bits are all "1" to indicate no button; at least one of the n bits is "0" to indicate the state of a key pressed (the input I / O line is pulled low by the corresponding diode level). According to this simple combination principle, n I / O lines can form 2 n – A simple combined keyboard circuit with 1 key, referred to as an n-order simple combined keyboard circuit. like figure 1 The essence of the 3-order simple combined keyboard circuit is a typical 8-3 line binary encoder in digital circuits.

[0024] Utilizing this n-order simple combination keyboard circuit can realize n...

Abstract

The invention relates to a computer keyboard with reorganizable keys. Adapters use a novel key value circuit. The key value circuit needs only a few resistors and diodes. The adapters can share the resistors. The resistors need not be placed in the adapters. The size of the adapters is reduced greatly. The adapters and the keyboard can be minimized.

Description

technical field [0001] The invention relates to a computer keyboard with reconfigurable keys. Background technique [0002] The Chinese patent application with application number 201310087950.8 discloses a computer keyboard with movable keys. It includes a keyboard substrate and keys arranged on the keyboard substrate, an adapter including all key value information on the keyboard is provided on the keyboard substrate under each key, and an adapter corresponding to the The corresponding key value information on the adapter corresponds to the matching contact block. Each adapter has the same structure, each adapter is a key-value circuit corresponding to all key-value information, each key-value circuit is composed of a set of contacts containing all key-values, and each contact corresponds to a key-value. [0003] And the bottom of each button is provided with a pressing block, which corresponds to the position of the contact that outputs the key value of the corresponding...
