Abstract

PURPOSE:To prevent the malfunction due to noise at power supply OFF state for the terminal unit, by controlling the number of a plurality of gatings connected to the transmission data line with the output signals of a plurality of integration circuits. CONSTITUTION:The data terminal ready signals 71, 72 from the terminal unit are inputted to the integration circuits 81 and 82, and the gate ciruits 91, 92 connected to the transmission data line of the transmission data signal from the terminal unit are provided. Further, the circuits 91, 92 are controlled with the output signal of the integration circuits 81, 82. Thus, the malfunction due to noise when the power supply of the terminal unit is disconnected, can be prevented.
