    a first control unit for, when first data exchanged with said second terminal and said third terminal is sequentially transmitted and received using said first communication unit, detecting whether said second terminal is in a first state in which said second terminal can exchange said first data with said first terminal and said third terminal or in a second state in which said second terminal cannot exchange said first data with said first terminal and said third terminal, thereby storing said first data exchanged during said second state in said memory as second data, and for transmitting said second data to said second terminal when a transition from said second state to said first state is detected,said second terminal including;

    a display;

    a second communication unit for transmitting and receiving data to/from said first terminal and said third terminal;

    a second communication control unit for, during said first state, sequentially transmitting and receiving said first data exchanged with said first terminal and said third terminal, and when said second terminal returns from said second state to said first state, receiving said second data transmitted from said first terminal, using said second communication unit; and

    a display control unit for causing said display to sequentially display said first data exchanged during said first state, and causing said display to display said second data over a predetermined time period when said second terminal returns from said second state to said first state.
