Abstract

PURPOSE:To prevent the lowering in signal level and malfunction due to momentary interruption, by discriminating a specific signal used for a cut-off signal at a logic section and cutting off the power supply for a terminal device based on it. CONSTITUTION:A terminal device is provided with a logic section (g) discriminating the cut-off signal of the power supply, a special cut-off signal is outputted to an optical cable (c) from a main body (a) at the cut-off of power supply, and when a cut-off signal is inputted to the logic section (g) via an optical relay device (d), it is discriminated at the logic section (g) to transmits the cut-off signal to the switch means of a power supply unit (e), and when the cut-off signal is received at a terminal device, the reception signal is transmitted to the main device (a) with the optical cable (c) and the transmission of the closing signal is stopped through the reception of this receiving signal at the main body (a).
