    • A transmitting apparatus of simple circuit configuration is provided as having turn off time (cut off delay time) of an output transistor shortened. The potential of a low-level signal is inputted to an input terminal of a first transistor through a resistor. The potential of a high-level signal is inputted to an input terminal of a second transistor through a resistor. A control circuit is connected to the input terminals of the first and second transistors and when a high-level signal is to be transmitted to the communication line, the control circuit enters a high-impedance state with respect to the input terminal of the first transistor and outputs a low-level signal to the input terminal of the second transistor. When a low-level signal is to be transmitted over the communication line, the control circuit outputs a high-level signal to the input terminal of the first transistor and develops a high-impedance state with respect to the input terminal of the second transistor.

    • A communication control device comprises a state change detecting section for outputting, upon detection of a state change in parallel input control signals, a transmission control instruction to a transmitting section. A standby time is provided between the time of detection of the control signal state change and the time of commencement of transmission of the serial signals by the transmitting section. For control signals to operate a controlled object at a desired time, the state change detecting section outputs the transmission control instruction a communication time plus the standby time earlier than the desired time.
