摘要:
An apparatus with a second movable portion that moves along an x-axis direction and a z-axis direction and a first movable portion that only moves along the z-axis direction is disclosed. The apparatus is provided with a fixed portion fixed to a support portion, a plurality of first spring portions connected to the fixed portion, a first movable portion connected to the plurality of first spring portions, a second spring portion connected to the first movable portion, and a second movable portion connected to the second spring portion. A spring constant of each of the plurality of first spring portions in the z-axis direction is lower than spring constants of each of the plurality of first spring portions in the x-axis and a y-axis directions respectively, and a spring constant of the second spring portion in the x-axis direction is lower than spring constants of the second spring portion in the y-axis and the z-axis directions respectively. The first movable portion is configured to move along the z-axis but not to move along the x-axis and the y-axis nor to rotate around the z-axis, and the second movable portion is configured to move along the x-axis and the z-axis with respect to the support portion.
