Abstract
An input device with a number of key sets is described. The input device has a first state when the key sets are configured in different levels, and a second state when the key sets are configured to be side-by-side.
Claims24
An input device comprising:
- a first key set having a first key panel, wherein a movement of said first key set is in a first direction;
- and a second key set having a second key panel, wherein a movement of said second key set is in a direction perpendicular to said first direction;
- wherein, when said input device is in a second state, said first and second key panels are in a plane and said first and second key sets are configured to be side-by-side, and when said input device changes from said second state to a first state, said first key set moves toward said second key set and said second key panel leaves said plane, such that said first and second key sets are configured be in a different level and said first and second key panels are face a same direction in said first state.
An input device comprising:
- a first key set having a plurality of keys, wherein said plurality of keys are arranged to form an indentation as an accommodating region;
- and
- a connection unit, said connection unit being movably connected to said first key set and selectively received in said accommodating region.
An input device comprising:
- a first key set having a first edge, and said first key edge having an indentation portion;
- a second key set having a second edge;
- and
- a second input unit disposed on said second key set;
- when said input device is in a first state, said first and second key sets are configured to be in a different level, said indentation portion accommodating part of said second input unit, and when said input device is in a second state, said first and second key sets are configured to be side-by-side and said first edge is substantially adjacent to said second edge.
