Abstract: A particle beam therapy apparatus has a position and posture setter that moves a movable body, that is at least one of the irradiation nozzle and the treatment table. A movement path of the movable body is determined when adapting the positional posture of the movable body from one condition among a plurality of prescribed conditions to another condition. An evaluation value is obtained for adapting the positional posture of the movable body to each of a plurality of prescribed conditions. This evaluation value is for a case of moving the movable body according to the movement path. A setting order is determined for adapting the positional posture of the movable body to each prescribed condition based on the evaluation value; and the positional posture of the movable body is adapted to each of the plurality of prescribed conditions by moving the movable body according to the determined movement path.

An ignition timing adjustment unit (43) is adapted to correct the ignition timing to a proper ignition timing in a retard region with reference to a maximum advance value based on a knocking signal outputted from a knocking detection unit (41) and a reference ignition signal (A) outputted from an external electronic control unit (37). The output signal from the ignition timing adjustment unit (43) can be thus promptly adjusted by retarding the ignition timing relative to a reference ignition timing given from the external electronic control unit (37) upon detection of engine knocking.
