    • While one ends of ropes are respectively tied to a −Y side leg section and a +Y side leg section of a frame caster, the other ends of the ropes hang down in a −Z direction via a plurality of pulleys fixed to the upper sections of frames that are each separated from an apparatus main body, and a weight having a weight corresponding to a half the weight to be reduced is tied to each of the other ends. In this case, even if the apparatus main body oscillates in vertical or lateral directions (normal directions of the pulleys) owing to the action of a vibration isolation table, the position of the weight only vertically moves by rotation of the pulleys, and the reduced amount of the apparatus weight does not vary. Further, since any coil springs are not used, sympathetic vibration with the apparatus main body and the vibration isolation table does not occur, which allows the attenuation characteristics of the vibration isolation table to be improved. Therefore, the exposure apparatus can be increased in size without inducing the cost rise.
    • 绳索的一端分别与框架脚轮的-Y侧腿部分和+ Y侧腿部分连接,绳索的另一端通过固定到上部的多个滑轮沿-Z方向下垂 各自与装置主体分离的框架,并且具有对应于要减小的重量的一半的重量的重量被连接到每个的另一端。 在这种情况下,即使装置主体由于振动隔离台的作用而在垂直或横向(滑轮的法线方向)上摆动,所以重量的位置仅通过滑轮的旋转而垂直移动,并且减小 设备重量的数量不变。 此外,由于不使用任何螺旋弹簧,不会发生与装置主体和隔振台的交感振动,这允许提高隔振台的衰减特性。 因此,曝光装置的尺寸可以增加,而不会导致成本上升。
