Abstract

PURPOSE: To elevate the operativeness and also make the equipment small-sized, by forming the equipment so that a data to be transmitted and received in response to a data transmission and receiving request from one equipment can be shifted to the other equipment together with the memory in which the data is stored effectively.
CONSTITUTION: In case when only the first equipment 1 is operated, since there is no data transmission and receiving request, it becomes possible to read and write a data by connecting the data line between the equipment 1 and RAM31 of the data transmission and receiving equipment 3 attached to the equipment 1, and also connecting the address signal receiver of the equipment 1 side and RAM31. On the other hand, in case when a data transmission and receiving request has been given from the equipment 1, the data line between the equipment 1 and RAM31 in accordance with the address signal from the equipment 1 is also cut off, and instead of it, the data line between the second equipment 2 and RAM31 is connected, also the address signal receiver of the equipment 2 side and RAM31 are connected, and a data between the equipment 2 and RAM31 can be read out and written.
