Abstract
A portable keyboard comprises a flexible substrate, at least two key groups disposed on the flexible substrate, a circuit board disposed on the flexible substrate, a connector electrically connected to the circuit board and a fixative element having a first connecting portion and a second connecting portion disposed on the substrate. As the flexible substrate is properly tensed to let the first connecting portion join the second connecting portion, the overlapped key groups and the circuit board are all wrapped by the flexible substrate. The folded keyboard is pocket size and easily transported and deployed.

A foldable keyboard, comprising:
- a first flexibility substrate, having a first side and a second side, the flexibility substrate could be twisted in any angle;
- a first key group connected to the first side of the first flexibility substrate;
- and
- a second key group connected to the second side of the flexibility substrate and overlapped on the first key group about a virtual axis formed by the first flexibility substrate and wrapped thereby.
A foldable keyboard, comprising:
- a flexibility substrate having a first surface and a second surface, the flexibility substrate could be twisted in any angle;
- a first key group disposed on the first surface;
- a second key group disposed on the first surface and spaced apart from the first key group;
- and
- a third key group disposed on the first surface and spaced apart from the second key group;
- wherein the first key group, second key group and third key group are overlapped each other about virtual axes formed by the flexibility substrate and wrapped thereby.
