たことを特徴とする位置設定装置。In a position setting device for establishing a position of a first object relative to a second object to be irradiated with radiation, the second object is
a light source for generating diffused light in a concentric pattern for providing a diffused light beam in a concentric pattern whose intensity changes from the center toward the edge to an object; and a second object to be irradiated with the radiation. said diffused light beam for reflecting a portion of said concentric pattern of said light beams and indicating by the intensity of said reflection the position of said second object within said diffused light beam; a light-reflecting target of substantially small size; a photodetector for receiving reflected light from the target and generating a signal proportional to the light intensity; and a control device for instructing the positional relationship between the object and the second object.
