A front shelf board 11 capable of placing the keyboard 10 is placed on the support plate 9 in front of the rear shelf board 12 so as to be tiltable downward, and longitudinally movable by hinging a rear end surface on a front end surface of the rear shelf board 12. When the rear shelf board 12 stops in a front limit position, the front shelf board 11 is held in an attitude of inclining forward at a required angle. <P>COPYRIGHT: (C)2004,JPO</p> |
