<p>PROBLEM TO BE SOLVED: To provide a keyboard device allowed to be compacted at the time of its non-use such as the carrying of the device though the device is a full keyboard device and having high durability and operability and a method for storing the keyboard device. SOLUTION: A hinge plate 3 mutually joins 1st and 2nd divided parts 1, 2 and switches these divided parts 1, 2 from a stored position on which the divided parts 1, 2 are vertically superposed to each other to a slid position on which the divided parts 1, 2 are separated through an interval on the same plane. When both the divided parts 1, 2 are relatively slid so as to come into contact with each other on the same plane, the divided parts 1, 2 are switched to a working position.</p> |
