Circuitry for detecting tonal signals, each of which has a particular nature in the frequency or time domain, while distinguishing them from each other. In the case of generating a flat plane projection image for one direction, radio-graphing is carried out on a projection image in a plurality of predetermined angle positions in the circumferential direction of the rotation center axis X1 and thereby one plane projection image is obtained. The first or second handover procedure is performed if the radio resource reconfiguration message includes mobility related information.
