PROBLEM TO BE SOLVED: To allow a transmitter side and a receiver side to share data in common by providing specific transmitter and receiver. SOLUTION: An information management equipment 1 is an electronic notebook provided with a dial tone output function and a paging signal reception function. In this case, a telephone terminal 2 such as a pushphone is connected to a center (central control station) 4 managed by a paging service company via a public line network 3 and a transmission station 5 is connected to the center 4. For example, the electronic notebook 1A sends a prescribed call number with a dial signal such as a DTMF signal via the telephone terminal 2, a call is made to other electronic notebook 1B of the same configuration as the electronic notebook 1A corresponding to the call number via the center 4 managed by the paging service company and a transmission station 5 from the public telephone line network 3 connecting to the telephone terminal 2. Thus, the information management equipment 1 at the transmitter side and the information management equipment 1B of the receiver side share data in common.
