Abstract:
1. An imaging apparatus having a table unit supporting a subject and a table mover for moving the table unit to an imaging space and which images the subject supported by the table unit moved to the imaging space by the table mover, comprising: a position detector for detecting a position in a vertical direction, of the table unit, wherein the table mover includes, a bottom plate provided downward from the table unit as viewed in the vertical direction, a support bar having a first shaft provided at one end thereof, which is pivotally supported by the bottom plate, and a second shaft provided at the other end thereof, which is pivotally supported by the table unit, said support bar supporting the table unit, an actuator having a third shaft provided at one end thereof, which is pivotally supported by the bottom plate, and a fourth shaft provided at the other end thereof, which is pivotally supported by the support bar, said actuator expanding and contracting according to pressure of fluid held thereinside to thereby rotate the support bar with the first shaft as the center to move the table unit in the vertical direction, and a pressure controller for adjusting a flow rate of the fluid held in the actuator to thereby control pressure based on the fluid held in the actuator, and wherein when the actuator moves the table unit from a first position in the vertical direction to a downward second position, the position detector detects the first position where the movement of the table unit is started by the actuator, and the pressure controller adjusts the amount of the fluid held in the actuator on the basis of the first position detected by the position detector to thereby control the pressure.
