<p>PROBLEM TO BE SOLVED: To provide a compact keyboard base which can improve the operability of a mouse, etc., by forming a horizontal hollow groove on the surface of a base board where a keyboard is mounted and adding the auxiliary tables into the hollow groove in such a way where the tables can horizontally slides and also can partly emerge at the side part of the base board. SOLUTION: A base board 1 is drawn out forward and one of both auxiliary tables 10 that holds a mouse 13 is drawn outward by a desired extent while a keyboard 12 is kept on both tables 10. Under such conditions, both keyboard 12 and mouse 13 are operated. At the same time, the operating surface necessary for the operation of the mouse 13 can be freely set by adjusting the draw-out extent of the table 10 that is drawn outward most. It is also possible to use the keyboard 12 after putting it into a space formed in a hollow grove between the right and left tables 10 when these tables 10 are drawn outward most.</p> |
