ABSTRACT:
A control apparatus for controlling movement of a table supporting an object under inspection in a medical diagnosis system includes a driving power unit for moving the table, a position detector for outputting a signal indicating a position of the table, a positioning servo-control unit for controlling the driving power unit so that the detected position signal coincides with a given desired value, a manipulating force detector for outputting a force signal corresponding to a manipulating force applied by an operator, a force-to-position conversion unit for converting the force signal into a position change quantity for the table, a force control unit for controlling the driving power unit in accordance with the position change quantity so long as the manipulating force is being detected, and a change-over unit for selecting either the positioning servo-control unit or the force control unit in response to operation of the operator.
