PURPOSE: To display a position of a searched object moving body to move in a necessary area on an image screen of a transceiver (or a receiver). CONSTITUTION: A transmitter A transmits a searching object moving body code read out of a storage part 1 in a feeble radio wave, and a transceiver B transmits a search demand signal inputted by an input part 6 in a feeble radio wave. These radio waves are received by a base station C, and are transmitted to a central device D, and are discriminated by a discriminating part 23, and a base station code of an area in which a transmitter corresponding to a demand from the transceiver exists, is transmitted to a base station which receives a search demand, and is transmitted from the base station in a feeble radio wave together with a code of one's own base station. This radio wave is received by the transceiver, and is processed into an image to be discriminatively displayed on a corresponding place of a base station map read out of a storage part 5 by a data processing part 11, and is displayed on an image screen of a display part 13 through a display driving part 12. The image to be displayed is rotated on the basis of data from an azimuth sensor 10, and the direction of the image screen and the actual direction are made to coincide with each other. |
