RADIOGRAPHY DEVICE

摘要

This radiography device is described in an embodiment with an x-ray examination device as an example, wherein, with a stage driving mechanism (7) formed from a combination of two or more linear drive mechanisms (x-axis/y-axis linear motors (7a, 7b)) when driving a stage (2) whereupon an object is mounted, a composite trajectory by each of the linear drive mechanisms (x-axis/y-axis linear motors (7a, 7b)) moves the stage (2) in a circular trajectory. In such a circumstance, each respective linear drive mechanism (x-axis/y-axis linear motors (7a, 7b)) is controlled with the absolute value (degree of driving) of the degree of movement per unit step being either greater than or equal to a prescribed value having positive real number value or zero, and it is possible to inexpensively ensure drive precision by moving the stage (2) in a circular trajectory with a trajectory range from a concentric small circle trajectory having half the size to a concentric large circle trajectory having twice the size.
