For example, a business menu 2 is displayed on a display device 30 by a business start switch 1, and transmission data 4 is sent to another terminal equipment by selection of a user business program 3 due to an operator. Thus, immediate transmission, reception, business management, collation, etc. are performed between terminal equipments without passing a central device to use highly the communication network system between terminal equipments. |
