<p><P>PROBLEM TO BE SOLVED: To provide a collapsible keyboard for freely changing the arrangement relationship between a control part and a keyboard, and arranging an operation surface and an installation surface of the keyboard in parallel even when the thickness of the control part and the keyboard is different. <P>SOLUTION: The control part 62 is constituted so as to be detachable from a first keyboard unit 3. The control part 62 and the first keyboard unit 3 are connected by a universal arm 67. The arrangement relationship between the control part 62 and the keyboard 1 can be freely changer in an allowable range by the universal arm 67. Even when the thickness H of a second arm member 67 and the thickness of the control part 62 are not in the same as the thickness h of the keyboard, a bottom part of the second arm member 67B and the control part 62 and a bottom surface of the keyboard 1 are flushed with each other when using the keyboard 1 by inclining a connecting angle of a first connecting pin 68A and a second connecting pin 68B, and are constituted so that a surface formed by a top surface of respective key switches 7 and 10 in the keyboard 1 becomes a parallel state to the installation surface of the keyboard 1. <P>COPYRIGHT: (C)2004,JPO</p> |
