Communication units are each provided with a wireless communication control section, a timing pattern generating section for generating a specified timing pattern, an informing device control section for controlling an informing device in accordance with an arbitrary timing and a timing pattern analyzing section for analyzing the transmitted timing pattern. The communication unit generates a specified timing pattern in the timing pattern generating section, controls its own informing device in accordance with the timing pattern by the informing device control section and transmits the timing pattern from the wireless communication control section to the communication unit. The communication unit analyzes the timing pattern transmitted from the communication unit and controls its own informing device according to the analyzed timing pattern. This allows a person to reliably find his or her own unit to be searched even when a plural number of persons search different devices in an identical place.
