Description
次に、本発明の実施の形態を図面と共に説明する。図1は、本発明が適用された通信装置の一例としての複合機1の構成を表すブロック図である。図1に示すように、本実施の形態の複合機1は、NCU(ネットワーク・コントロール・ユニット)部10と、そのNCU部10を制御する制御手段及び判断手段の一例としてのCPU30とを備えている。
次に、この複合機1においてCPU30がROM31に記憶されたプログラムに基づいて実行する制御を、図2のフローチャートを用いて説明する。なお、図2の処理は、複合機1の電源投入時に開始される。
このように、本実施の形態の複合機1では、電源投入時及び一定時間が経過する度に(S33:Y)、誤接続検出プロセス(S10)を実行することができる。また、S31〜S33の処理による待機中に電流検知部19Aに電流が流れた場合にも(S32:Y)、誤接続検出プロセス(S10)が実行されるので、電源投入後に電話機接続端子11に電話回線70が誤接続された場合にも即座にその誤接続を検出することができる。すなわち、電源投入後に電話機接続端子11に電話回線70が誤接続された場合、回線接続端子12に誤接続された電話機50がオフフックされるとか、DPSリレー15が擬似呼出回路18側に切り換えられるとかしたときに上記閉回路が形成され、電流検知部19Aに電流が流れて(S32:Y)、誤接続検出プロセス(S10)が実行されるのである。
