<p>PROBLEM TO BE SOLVED: To provide a keyboard device capable o incorporating a new structure to a notebook type information processing apparatus advantageously in regard to space, and reducing constraints in incorporation. SOLUTION: An information processing apparatus body 1 has a key top 3 arranged thereon, and an opening and closing lid 2 has a display surface 4. The information processing apparatus body 1 has a fixedly arranged support plate 9, a movable circuit board 10, a key support 7 supporting the key top 3 and coupled with the support plate 9 and the circuit board 10, a switch 11 closing a normally opened contact 111 by movement of the opening and closing lid 2 to a closed position, and a motor 12 and an actuator 13 driven when the normally opened contact 111 is closed and moving the circuit board 10. When the opening and closing lid 2 is in an opened position, the circuit board 10 is moved to a stationary position and the key top 3 is moved to a usage position via the key support 7. When the opening and closing lid 2 is in the closed position, the circuit board 10 is moved to a moved position by a drive of the motor 12, and the key top 3 is moved to a storage position lower than the usage position via the key support 7.</p> |
