Pose change apparatus and inspection method

A pose change apparatus capable of changing a pose of an inspection target with the inspection target kept in a held state, the pose change apparatus comprising:

• a first output shaft rotatable around a first rotational axis;
• a first member rotatable around the first output shaft according to a rotation of the first output shaft;
• a second member disposed on the first member and operable to tilt the inspection target in a direction along a second rotational axis tilted at an angle with respect to the first rotational axis;
• a second output shaft disposed on the second member and operable to rotate the inspection target around the second rotational axis;
• a first actuator configured to rotate the first output shaft;
• and
• a second actuator configured to rotate the second output shaft around the second rotational axis in an opposite direction from a direction in which the first member is rotated when the first output shaft is rotated around the first rotational axis,
• wherein the first actuator and the second actuator are configured to be synchronously driven so as to cause the inspection target to perform a conical motion about a point at which the first rotational axis and the second rotational axis intersect with each other.
