。Immediately, the master station (2) gives within the reference timing period,
Calculated from the reference timing TO, the timing of TH is sent to the communication device (3-1), and the timing of T2 is sent to the communication device t(
3-2), each timing is similarly given to the communication device t(3-n) at the timing of Tn. These communication devices (3-1) to (3-n) have a frame structure of 0 sends and 6 data that can transmit data to the required destination 4M devices using the given timings T1 to Tn. r[! In the format shown in Figure 3, the address field (A) is surrounded by a flag field (A) and the find field (A).
C) A data field CDATA input check sequence (Fe2) t- is generally used.

端末装置等に一致検出に同期して創作する。Once the above frame is received on the transmission line fl+ made by Tsushin W, which will be the receiving side, and the frame matches the own address, the message 1i
It processes data according to the import command, and creates data in synchronization with the detected match on a connected friend terminal device, etc.

きず、効率が低い欠点があつ几。Conventional devices are configured to once receive all data sent from other communication devices and only capture data that matches its own address, so the address of the destination The disadvantage is that it is necessary to set the address and to detect a match with the own address. Also, as long as the received data does not match the own address, it is in a temporary state, so when you want data from a certain other party, you cannot receive data unless the other party specifies you.
It has flaws, low efficiency and drawbacks.

。Is there a drawback to this invention over the conventional ones mentioned above? Each communication device receives and stores all data sent from other communication devices, thereby verifying the destination address at the source and the address at the receiver. - Eliminates the need for scattered detection charges and simplifies the circuit configuration for transmitting and receiving.

。In addition, since this invention stores all data transmitted by other communication devices, data from other) devices can be used immediately without any delay, making it efficient. An embodiment of the present invention will be described with reference to the drawings. Fourth
In the figure, (ta) is the transmitter, (4b) is the receiver (a),
(5) is a shared memory in which each communication device has a transmission area (shaded area in the figure) in which all of its own transmission data is stored, and a reception area in which data received from other communication devices is stored.
