PURPOSE:To reduce the job for the operator at a contract terminal, by automatically transmitting a reminder message to a non-written terminal, through the check of the non-written terminals from terminals to which the write is either instructed to a mail box or scheduled. CONSTITUTION:A storage device 7 of a mail box managing device 10 is provided with a display area 3 and an address area 8, and an address table part 2 for write scheduled terminals and a general storage part 9 are allocated in the area 8. In writing to the mail box 1, a write message Mw is transmitted to a box 1, a write address Aw is given to a comparison circuit 4 of the device 10, a control circuit 6 is started at a time set to a start circuit 5, and through the control of the circuit 6, the address inputted at the circuit 4 and that of the area 8 displayed in the area 3 are compared. As a result, if the corresponding data is not written in the box 1, a transmission address As is transmitted from the circuit 6 and a reminder message Ms is automatically transmitted from a specific area M1 to a terminal. |
