As a result, in the case of “mismatch”, the process proceeds to step 909 and the next display device 9 (for example, I
Data transmission to the D number “b”) is performed.

On the other hand, if the ID information of the incoming data matches the ID information of the display device 9, the incoming data is fetched into the reception processing section 9A of the display device 9 and temporarily stored (step 903). ). Thereafter, the display data number, that is, the control device 1 is added to the received incoming data.
In FIG. 4, the display data number set in step 108b of FIG. 4, more specifically, the display data D1 and D2 of the transmission data whose format is shown in FIG.
It is determined whether or not the display data is stored in the display data storage unit 9A1 in the display device 9 (step 904).

As a result, if it is determined that there is (YES), the display data of the corresponding number, that is, the corresponding page content is displayed on the data display section 9B (step 905). This operation is repeated until there are no more display data numbers in the incoming data, and these display data numbers are fetched and displayed on the data display section 9B.

If there is no data to be displayed on the data display section 9B of the display device 9 ("N" in step 904)
In the case of "O"), or after displaying all the data of the corresponding number on the data display section 9B, it is determined whether or not there is an erase data number among the incoming data fetched as described above (step 905). In this case, it is determined whether or not the erasure data E1 of the transmission data whose format is shown in FIG. 5 is in the display data storage unit 9A1 shown in FIG. 2 (step 904). .

As a result, there is an erase data number (“YE
S "), the display data of the corresponding number is erased from the data display section 9B (step 907), and until the erased data number is exhausted, the erased data number of the incoming data is fetched. The operation of deleting the display data from the data display section 9B is repeated.

Thereafter, when the display / erasure on the data display section 9B is completed by the above operation, the data display section 9B
The display data number displayed on B is updated (step 908), and data is transmitted to the next display device 9 (step 909), and the operation is completed.
