An input system includes a first base portion and a second base portion that each include a keying surface. A base portion manipulation mechanism couples the first base portion to the second base portion. The base portion manipulation mechanism includes a moveable coupling that is configured to allow relative movement of the first base portion and the second base portion into at least one of a tented orientation and a splayed orientation. A locking mechanism provides a biasing force that causes an engagement between portions of the moveable coupling that resists relative movement of the first base portion and the second base portion absent an unlocking force, wherein the locking mechanism is responsive to the unlocking force that overcomes the biasing force to allow relative movement of the first base portion and the second base portion into the at least one of the tented orientation and the splayed orientation.

A key structure includes a switch circuit board, a triggering assembly, a keycap and an elastic element. The triggering assembly is disposed over the switch circuit board. The elastic element is arranged between the keycap and the triggering assembly. As the keycap is moved, the triggering assembly is pushed by the elastic element. The elastic element includes a concave part. The concave part is located at a top end of the elastic element and contacted with the keycap. When the elastic element is pushed by the keycap, the concave part is subjected to deformation, so that a movable distance of the keycap toward the switch circuit board is increased. By using the key structure, the tactile feel of depressing the keycap is enhanced.

A portable keyboard includes a plurality of key assemblies including a plurality of key tops, a main body of a pillar shape of n angles, which is located in the vicinity of a first key assembly among a plurality of the key assemblies and includes a plurality of sides, a flexible connection member configured to connect a plurality of the key assemblies with the main body, and a main board configured to be embedded in the inside of the main body and process input signals inputted from a plurality of the key assemblies. In this case, the main body includes a first side of which one edge of the first side is connected with the flexible connection member, a second side adjacent to another edge of the first side and the second side of which an angle with the first side is equal to or greater than 90 degrees, and a cradle configured to combine one end of the cradle with the second side using a hinge to make the cradle to be rotated and the cradle configured to be contacted with the second side.

Separated keyboard and method for changing keyboard layout for each communication connection disclosed. The separated keyboard device includes a main keyboard unit connected to a digital processing device by wire or wirelessly and a sub keyboard unit physically separated from the main keyboard unit and connected to the main keyboard unit by wire or wirelessly.
