Foldable keyboard

摘要

A control part is provided independently from a keyboard and is connected to a first keyboard unit through a jointed-arm. The control part can be placed in substantially the back center of the keyboard through the use of a free turning property of the jointed-arm. A PDA connected to a connector member of the control part can be placed in a position where a keyboard user can view the most easily, with the result that the operationality of the keyboard can be enhanced.
