Vertical rail 8 movably connected to rail 4 in a perpendicular relationship
, a vertical cursor 12 movably attached to the vertical rail 8, a link 26 pivotally supported to the vertical cursor 12 so as to be swingable in a plane perpendicular to the two surfaces of the drawing board, In a device comprising a bed 16 connected to the open end side of a link 26 so as to move in conjunction with the movement of the link 26, a bending spring 50 is set such that its initial elasticity is zero when both ends are substantially overlapped. One end of the vertical cursor 12
The link 26 is rotatably connected to the side of the link 26, and the link 2
6', the other end of the spring 50 is connected so that the biasing force of the sling 50 acts in a direction opposite to the direction of rotation due to the weight of the head 16. Balance device in support equipment.
