An automated banking machine is operative to conduct transactions in response to HTML documents and TCPIP messages exchanged with a local computer system through an intranet, as well as in response to messages exchanged with foreign servers in a wide area network. The invention is characterized in that the plurality of optical positioning devices with the visual axis tracking function are provided for measuring and analyzing 3D movements of the plurality of point light sources to achieve the effect of a virtual input and simulator. The transmission apparatus includes a data transmission unit transmitting the data, a reception state notification reception unit receiving the reception state notification, and a retransmission determining unit making the data transmission unit retransmit data specified in the reception state notification as unreceived data. The handoff utilizes a session protocol message for handoff. Since the agglomeration force produced by the remnant magnetization is utilized, the addition of a granulating agent may be omitted.
