<p>PURPOSE:To use a simple device to always direct an output device toward an input device by controlling a driving means so as to change the direction of the output device based on information of the input position detecting means. CONSTITUTION:When moving a keyboard 5, since a signal line 6 is always in a state of being stretched, a keyboard direction detector 4 is pointed at the direction of keyboard 5. Then, information of the detector 4 is transferred to a display unit driving table 3. Based on this information, the detector 4 judges that the direction of the keyboard 5 has changed, and the display unit driving device directs the display unit 2 so as to face toward the keyboard 5.</p> |
