PURPOSE:To reproduce the state of the input from the sender side with fidelity at a receiver side by providing a read controller receiving a signal of a timer of the same period of timer by which an input device fetches coordinate information and reading coordinate information from a reception buffer. CONSTITUTION:A data received from a non-real time transmission line 7 is stored in a reception buffer 4 through a transmission control section 3. On the other hand, a timer 6 giving a signal of a prescribed period to an input device 1 gives a signal of a same period to a read controller 8. Every time the read controller 8 receives a signal from the timer 6, the reception data whose validity is confirmed is read from the reception buffer 4 by one coordinate and the data is transferred to an output display device 5, in which the data is displayed. Thus, since an output display device 5 displays the data at a same period as the fetch of the coordinate, the state of the input is reproduced from the display at the receiver side with fidelity regardless of a delay in the transmission line. |
