PURPOSE:To correct keyed-in data even by a CRT terminal equipment and to decrease the processing burden of a central processing unit by correcting the data received from the CRT terminal equipment executed by the central processing unit with a terminal controllor. CONSTITUTION:A CRT terminal equipment control part is surrounded by an alternate long and short line. A channel interface part 31 is connected to a controllor 32 to control the transmission and reception of the data of the central processing unit 10 and a CRT terminal equipment 40. In the controllor 32, a receiving data counter A and a receiving data memory B are included, a memory part 33 is connected, a microprogram and data are controlled and accumulated, connected through an input/output interface part 34 to the CRT terminal equipment 40 and the giving and taking of the data are executed. Thus, the data keyed in from the CRT terminal equipment 40 can change the keyed-in data transferred to a terminal controllor 32 simultaneously when the keying-in is executed and the processing burden of the central processing unit can be decreased.
