DISPLAY INFORMATION SUPPLYING SYSTEM TO DOT MATRIX ELECTRIC DISPLAY MACHINE AS WELL AS DISPLAY INFORMATION ADAPTER DEVICE USED FOR THIS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a novel display information supplying system which allows the easy and inexpensive display information operation to a dot matrix electric display machine as well as a display information adapter device used for this system. SOLUTION: Desired data is retrieved by accessing an NTT captain system 7 via a modem 6 built in the display information adapter device 5 when a setting time comes. Only the chaaracter signals in the retrieved data are detected by a CPU 11 and are stored in a first memory 8. On the other hand, display information, such as commercial messages, are formed by the CPU 11 according to the operation of a keyboard 2 in a management center 13 and are forwarded to the display information adapter device 5 via a modem 10 and are stored in a second memory 9. The data stored in the first memory 8 and the second memory 9 are combined according to a set program by the CPU 11 and are delivered to dot matrix electric display machine 14 by a signal transmission section 12.
