<p><P>PROBLEM TO BE SOLVED: To provide a top plate for performing a mouse operation without generating any failure such as fatigue or pain or the deformity of bone. <P>SOLUTION: A top plate 1 is provided with a keyboard area 5 where a keyboard can be placed and a mouse area 9 positioned at the right and left outside. The mouse area 9 is loosely inclined to the right and left outside, and the front part is loosely inclined forward so as to be made lower toward the front. The rear part may be loosely inclined backward. The upper face of the mouse area 9 is inclined toward the right and left outside so that it is possible for a user to twist his or her wrist in the minimum extent, and to prevent any excess load from being imposed on the bone, tendon or muscle in order to prevent the generation of any failure. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
