ター装置１へ送信される（ステツプ82、83）。 In the drawing, step 71 determines the presence or absence of received information, and if the determination is YES, the received information is stored in the storage unit 50.
Once stored in the memory area 52 of
72, the storage area 6 of the storage unit 6 is transferred from the storage area 52.
Transferred to 3. Also, if the judgment is NO, the input/output operation is restricted and the process waits for sending/receiving information (step
73). In the next step 74, it is determined whether or not the received information includes data requesting transfer of line information.If the judgment is YES, the line information accumulated in the storage area 53 of the storage unit 50 is The data is transferred to the storage area 63 of. Further, if the determination is NO, other reception processing (for example, information processing other than line information) is executed (step 76). Next, in step 77, the counter i in the arithmetic control section 61 is set to 1, and in step 78, the ID code 1 in the storage area 65 is set to 1.
It is checked whether the information corresponding to the ID code 1 is stored in the storage areas 63 and 64, and if the determination is YES, the information related to the ID code 1 is transferred to the storage section 62 (step 79). On the other hand, if the determination in step 78 is NO and the transfer process in step 79 is executed, the contents of counter i are incremented by 1 in step 80, and then the information of ID code 2 is checked and processed in steps 78-79. is executed. In this way, the same processing is executed until the contents of the storage area 65 specified by the counter i reach the table stopper, and in the storage area 62, various information including line information is edited as a series of transmission information in the order of ID code numbers. . When the determination in step 81 is YES, the edited transmission information in the storage area 62 is temporarily transferred to the storage area 52 of the storage section 50 and then transmitted to the center device 1 (steps 82 and 83).
