ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a keyboard connected to a computer, and more particularly to a keyboard whose occupied space on a desk or the like can be reduced when it is not in use.
In the case where a conventional computer is placed and used on a desk, a keyboard attached to the computer occupies quite a large space, thereby becoming an obstruction to other work on the desk. As a result, some ideas have been adopted, one of which is that a keyboard is stood against a computer when it is not in use. However, conventional keyboards are not designed so as to be stood against something, so that they are liable to fall down due to feeble vibrations and impacts when they are leaned against computers. This may cause a failure or breakage of the keyboards.
SUMMARY OF THE INVENTION
An object of the present invention is therefore to provide a keyboard that is free from the above-mentioned disadvantage of the conventional keyboards and allows a predetermined space to be secured on a desk when the keyboard is not in use.
According to an aspect of the present invention, there is provided a keyboard which comprises: a keyboard body; and one or more stands fixed to a place to allow the keyboard body to be vertically supported above the place.
Each of the one or more stands comprises: a first stand member fixed to the above-mentioned place; a second stand member coupled to the keyboard body and rotatably supported by the first stand member; and a fixing means for fixing the first stand member to the second stand member when the second stand member is rotated by a desired angle.
The fixing means fixes the first stand member to the second stand member by means of frictional engagement, a magnetic force, or a locking function.
