を含んでいること を特徴とする水中用ページング装置。[Claims for Utility Model Registration] An underwater paging device consisting of a combination of a relay means for receiving a radio wave signal and generating an ultrasonic signal, and a paging receiver capable of responding to both the radio wave signal and the ultrasonic signal. , the relay means includes: a signal converter that is installed on the ground and converts a radio wave signal in the air into an ultrasonic signal; and an ultrasonic radiator that is installed underwater and that radiates the ultrasonic signal from the signal converter. The paging receiver includes: a first receiving means for receiving a radio wave signal in the air; a second receiving means for receiving an underwater ultrasonic signal; and the first or second receiving means. An underwater paging device characterized by comprising a selection means for selecting one of the means depending on the use in the air or underwater.
