A user I/F unit 200 transmits an instruction given by a user to an access management unit 100 and displays data on a monitor 76. The access management unit 100 transfers requirements to a communication control unit 300 and a data management unit 400 in response to the instruction from the user, transfers data from a communications host to the data management unit 400, and outputs data from a database 410 to the user I/F unit 200. The data management unit 400 writes data into the database 410 and reads storage data from the database 410 in response to the requirement from the access management unit 100. Data transmitted from the communications host are sorted out according to communication services and stored in the database 410. The communication control unit 300 translates the requirement from the access management unit 100 to a menu number representing each communication service available from the communications host or a command and sends the translated requirement to a communication I/F unit 500. This structure enables input data to be sorted out and stored without any overlap.
