Abstract
A folding keyboard includes a fixed key module and one or more mobile key modules. The key modules are joined together by links between them. Two ends of the links between the key modules are joined at asymmetric positions. The mobile key module can turn 180 degrees to lie against the fixed key module. The folding keyboard is capable of being frontally folded, showing the whole arrangement of keys after unfolding, and being used immediately after unfolded. Moreover, the folding keyboard can be relatively shrunk by way of compression of the key units to reduce the thickness, and can be designed to be a triply-folded or quadruply-folded structure.
