Abstract: A spring member is provided between two pressed bodies facing each other in a first direction and includes base plates stacked in the first direction. Each base plate is provided with spring protrusions protruding toward either one pressed body of the two pressed bodies and pressing the two pressed bodies in directions such that the pressed bodies move away from each other in the first direction. Between two base plates adjacent to each other in the first direction, a base plate positioned closer to the one pressed body is provided with an insertion hole into which a spring protrusion of the other base plate is inserted in a state of penetrating therethrough in the first direction. Among portions in an along-plane direction along a plane orthogonal to the first direction provided with the spring protrusions, the spring constant of at least one portion is different from that of another portion.

Abstract: An object of the present invention is to provide a sample holder that can carry out a series of observations in which a rotational series image at arbitrary angles, namely, from ?180° to +180° around the x-axis of an observation region and a rotational series image at arbitrary angles, namely, from ?180° to +180° around the y-axis are obtained without taking a sample out of a sample chamber.

Abstract: A sample micromotion mechanism adapted to minimize an influence of a disturbance and adjust a sample drift rapidly and with high accuracy, and designed so as to be a compact, easy-to-place sample micromotion mechanism of a side-entry type that suppresses the occurrence of the sample drift and generates/displays high-resolution monitoring images and precisely drawn patterns. A charged particle device employing the sample micromotion mechanism operates followed by deformation which causes a strain. A strain measuring unit measures such strain. The sample micromotion mechanism imparts micromotion so as to reduce the strain in accordance with the measured strain value, thereby reducing deformation of the sample micromotion mechanism.
