ABSTRACT:
The present invention relates to a two-piece keyboard wherein each piece mutually cooperates and reversibly engages with the other piece to rotate between a first configuration used for standard typing and a second configuration wherein the keyboard is portable. A guide mechanism and/or a spring loading mechanism can be employed to easily facilitate movement between the configurations and a locking mechanism can selectively lock the keyboard in either the first or second positions.
