To provide a vertical stage device for an elevation mechanism using a wedge mechanism improved in following capability of elevation motion of a wedge upper part to horizontal motion of the wedge lower part.
The vertical stage device has a constitution elevating a sample stage 13 in vertical direction and is provided with an elevation wedge mechanism 15 facing in each slope a wedge upper part 15b moving vertically which is provided with a sample stage 13 and guided by a vertical guide 14d to a wedge lower part 15a freely movable in horizontal direction with a motor 17. Here, the wedge upper part 15b is connected with connectors 24, 25 and 26 to the wedge lower part 15b. When the wedge lower part 15a is moved in horizontal direction, the wedge upper part 15b is elevated so as not to make a gap between the wedge lower part 15a and the wedge upper part 15b.
