【００８３】
図１における教室１の教師端末２１の操作画面（図４参照）において、オールコールアイコン２５１を教師が操作すると、教師端末２１よりＬＡＮケーブル１０５及びネットワーク装置５０を介して制御信号Ｃ（ｔ１，ｔ２，ｓ１，…，ｓｎ）が音声通信制御装置４０に送信される。これにより、教室１の音声通信制御装置４０では、図３（Ａ）における教師端末ｔ１音声入力に接続された音声入力スイッチＳＷｔ１−ｔ２、ＳＷｔ１−ｓ１、…、ＳＷｔ１−ｓｎが同時にＯＮとなる。そして、図５の太線で示す通り、教師端末入力端子９１より教師端末ｔ１音声入力に入力された教師端末２１からの教師音声が教室１内の全学習者端末７１に送出されるとともに、教師端末ｔ２音声出力に接続された教師端末出力端子８２より教室２の音声通信制御装置４０に送出される。
【００８４】
ここで、制御信号Ｃ（ｘ，ｙ１，…，ｙｎ）とは、音声通信制御装置４０に対して音声入力スイッチＳＷｘ−ｙ１，…，ＳＷｘ−ｙｎを同時にＯＮする旨の制御指示を示す。ここでは、上記教師端末ｔ１音声入力及び出力は自己の教室（教室１）の教師端末２１に対応し、教師端末ｔ２音声入力及び出力は他の教室（教室２）の音声通信制御装置４０に対応している。

同時に教室１の教師端末２１よりＬＡＮケーブル１０５、ネットワーク装置５０及びルータ装置５１を介して別の制御信号Ｃ（ｔ２，ｔ２，ｓ１，…，ｓｎ）が教室２，３，…，Ｎの音声通信制御装置４０に送信される。これにより、各々の教室の音声通信制御装置４０において、教師端末ｔ２音声入力に対応する音声入力スイッチＳＷｔ２−ｓ１、ＳＷｔ２−ｔ２、ＳＷｔ２−ｓ１、…、ＳＷｔ２−ｓｎが同時にＯＮとなる。そして、図６の太線で示す通り、教師端末入力端子９２より教師端末ｔ２音声入力に入力された教室１からの教師音声が当該教室内の全学習者端末７１に送出されるとともに、教師端末ｔ２音声出力に接続された教師端末出力端子８２より次教室の音声通信制御装置４０に送出される。
【００８６】
ここで、教室ｘ（ｘは１〜Ｎ）における教師端末ｔ２音声入力に対応する教師端末入力端子９２は、アナログ線１０４により教室ｘ−１の教師端末ｔ２音声出力に対応する教師端末出力端子８２と接続されているので、結果として教室ｘ−１の音声通信制御装置４０の教師端末入力端子９１に入力された音声、すなわち教室１の教師音声を全教室１〜Ｎの全学習者端末７１へ送出することができる。
【００８７】
なお、ここでは全教室の全学習者へ教室１の教師音声を送出することを例にとって説明したが、各教室へ送出する制御信号Ｃの第２項以降を適宜変更することで任意の教室の１ないし複数の学習者に限定して教師音声を送出することも可能である。

【００８９】
ここで、制御信号Ｃ（ｘ，ｙ１，…，ｙｎ）；Ｃ（ｚ，ｗ１，…，ｗｍ）；…は、図３（Ａ）における音声入出力切替スイッチＳＷｘ−ｙ１，…，ＳＷｘ−ｙｎを同時にＯＮし、さらにＳＷｚ−ｗ１，…，ＳＷｚ−ｗｍ，…も同時にＯＮする旨の制御指示を示す。
【００９０】
なお、ここでは教室１以外の教室に配置された単独の学習者端末Ｙの音声を聴取することを例にとって説明したが、制御信号Ｃ（ｓＹａ，ｔ２）を当該音声通信制御装置４０の制御信号に付加することにより、任意の教室に属する２つの学習者端末Ｙ及びＹａの音声を同時に聴取することも可能であるし、同様の手順で順次制御信号を付加することで３名以上の学習者を対照とすることもできる。
【００９１】

【００９３】
なお、ここでは教室１以外の教室に配置された単独の学習者端末Ｙと教室１の教師端末２１との音声通話を例にとって説明したが、制御信号Ｃ（ｔ２，ｓＹａ）；Ｃ（ｓＹａ，ｔ２）；Ｃ（ｓＹ，ｓＹａ）；Ｃ（ｓＹａ，ｓＹ）を教室Ｘの音声通信制御装置４０の制御信号に付加することにより、教室Ｘに属する学習者端末Ｙａを加えた３者間の相互通話も可能であるし、同様の手順で順次制御信号を付加することで３名以上の学習者を対象とすることもできる。
【００９４】
また、教室１内の各学習者端末７１と相互通話する場合は、音声通信制御装置４０に対して制御信号Ｃ（ｔ１，ｓＹ）；Ｃ（ｓＹ，ｔ１）等を送信することにより、直接教師端末２１と該当する学習者端末との間で音声を入出力させればよい。

【００９６】
なお、ここでは教室１以外の教室に配置された単独の学習者端末Ｙと教室１の教師端末との学習者自らの意思による音声通話を例にとって説明したが、制御信号Ｃ（ｔ２，ｓＹａ）；Ｃ（ｓＹａ，ｔ２）；Ｃ（ｓＹ，ｓＹａ）；Ｃ（ｓＹａ，ｓＹ）を教室Ｘの音声通信制御装置４０の制御信号に付加することにより、教室Ｘに属する学習者端末Ｙａを加えた３者間の相互通話も可能であるし、同様の手順で順次制御信号を付加することで３名以上の学習者を対象とすることもできる。
【００９７】
また、教室１内の各学習者端末７１との相互通話をする場合は、音声通信制御装置４０に対して制御信号Ｃ（ｔ１，ｓＹ）；Ｃ（ｓＹ，ｔ１）等を送信することにより、直接教師端末２１と該当する学習者端末との間で音声を入出力させればよい。

【００９９】
なお、ここでは教室１以外の教室に配置された単独の学習者端末Ｙと教室１の教師端末２１との音声通話を例にとって説明したが、制御信号Ｃ（ｓＹａ，ｔ２，ｓ１，，…，ｓＹａ−１，ｓＹａ＋１，…，ｓｎ）を教室Ｘの音声通信制御装置４０の制御信号に付加することにより、教室Ｘに属する学習者端末Ｙａを加えた３者間の相互通話に拡張することもできるし、同様の手順で順次制御信号を付加することで３名以上の学習者を対象とすることもできる。
【０１００】
また、教室１内の学習者端末との音声通話を聴取させる場合は、音声通信制御装置４０に対して制御信号Ｃ（ｔ１，ｓ１，…，ｓｎ）；Ｃ（ｓＹ，ｔ１，ｓ１，…，ｓＹ−１，ｓＹ＋１，…，ｓｎ）を送信することにより、直接教師端末２１と当該学習者端末の音声を各端末に入出力させればよい。

また、教室１の教師端末２１の操作画面（図４参照）において、教室Ｘの学習者端末Ｙに通話要求マーク２４０が付与された状態でモデルアイコン２５５及びコールレスポンスアイコン２５４を操作すると、教師端末２１よりＬＡＮケーブル１０５及びネットワーク装置５０を介して、教室１の音声通信制御装置４０に対し制御信号Ｃ（ｔ１，ｔ２，ｓ１，…，ｓｎ）；Ｃ（ｔ２，ｔ１，ｓ１，…，ｓｎ）が送信される。また同時に、ＬＡＮケーブル１０５、ネットワーク装置５０及びルータ装置５１を介して、教室Ｘの音声通信制御装置４０に対し制御信号Ｃ（ｔ２，ｓ１，…，ｓｎ）；Ｃ（ｓＹ，ｔ２，ｓ１，…，ｓＹ−１，ｓＹ＋１，…，ｓｎ）が、その他の教室の音声通信制御装置４０に対し制御信号Ｃ（ｔ２，ｔ２）がそれぞれ送信される。これにより、任意教室の任意学習者の音声が教室１の教師端末に送出されると同時に、教師音声を当該学習者端末に送出されるので、任意の学習者端末と教師端末との間での相互通話内容を教室Ｘ内の他の全学習者端末に送出することができる。
【０１０２】
なお、ここでは教室１以外の教室に配置された単独の学習者端末Ｙと教室１の教師端末との学習者自らの意思による音声通話を例にとって説明したが、制御信号Ｃ（ｓＹａ，ｔ２，ｓ１，…，ｓＹａ−１，ｓＹａ＋１，…，ｓｎ）を教室Ｘの音声通信制御装置４０の制御信号に付加することにより、教室Ｘに属する学習者端末Ｙａを加えた３者間の相互通話に拡張することもできるし、同様の手順で順次制御信号を付加することで３名以上の学習者を対象とすることもできる。

【０１０４】
さらに、任意の教師端末２１から図４に示す教師端末２１の操作画面において音声教材送出切替ボタン２８０をＯＮにすると、教師端末２１よりＬＡＮケーブル１０５及びネットワーク装置５０を介して制御信号Ａ（１，ｔ２，ｓ１，ｓ２，…，ｓｎ）が教室１の音声通信制御装置４０に送信される。そして、予め対象音響機器切替ボタン２７０の操作により指定され、対象音響機器表示部２６０に表示されている音響機器に対応する、音声教材送出切替スイッチ４２の音響機器ｐ１音声入力に接続された音声出力スイッチＳＷｐ１−ｓ１、ＳＷｐ１−ｓ２、…、ＳＷｐ１−ｓｎ及びＳＷｐ１−ｔ２が同時にＯＮとなる。例えば、音響機器ｐ１音声入力に対応する音響機器としてＶＴＲが指定されている場合は、教室１内の全学習者端末と教師端末ｔ２出力端子に教材として指定された音響機器であるＶＴＲの音声が出力される。
【０１０５】

（第２実施形態）
図１０は本発明の第２実施形態に係る授業支援システムの構成を示したブロック図、図１１は第２実施形態の授業支援システムにおける音声通信制御装置の接続状態を示した構成説明図である。但し、図１に示した第１実施形態と同様の部分は同一符号を付して説明し、かつ、その説明を適宜省略する。
【０１１０】
第２実施形態の授業支援システムでは、複数の教室１，２，…，Ｎにおける授業支援装置は、第１実施形態と同様の構成となっている。すなわち、教師端末２１と複数の学習者端末７１はネットワーク装置５０を介してＬＡＮケーブル１０５により相互に接続される。また、教師端末２１にはアナログ線１０４で音声入出力装置１１が接続され、各学習者端末７１にはそれぞれアナログ線１０４で音声入出力装置６１が接続されており、これらの教師用の音声入出力装置１１及び学習者用の各音声入出力装置６１は音声通信制御装置４０を介してアナログ線１０４で相互に接続されている。また、教師用の音声入出力装置１１及び学習者用の各音声入出力装置６１には、ヘッドセット１０１が接続されている。
【０１１１】
第２実施形態の第１実施形態と異なるところは、教室１の音声通信制御装置４０と他の教室の音声通信制御装置４０とのアナログ線１０４による接続の仕方にある。すなわち、図１１（Ａ）に示すように、音声通信制御装置４０には少なくともＮ個の教師端末入力端子９１〜９Ｎ及び教師端末出力端子８１〜８Ｎが設けられており、教室１，２，…，Ｎ間は教師端末入出力部の未使用部分を利用して教室１と他の教室２〜Ｎとがいわゆるスター型に接続されている。この場合、アナログ線１０４を介して教室１の教師端末入出力端子８２，９２と教室２の教師端末入出力端子８２，９２、教室１の教師端末入出力端子８３，９３と教室３の教師端末入出力端子８２，９２、…、教室１の教師端末入出力端子８Ｎ，９Ｎと教室Ｎの教師端末入出力端子８２，９２という対応の仕方で相互接続され、教室１の音声通信制御装置４０と残りの全ての教室の音声通信制御装置４０とが直接アナログ線１０４を介して接続されている。

次に、以上のように構成された第２実施形態の授業支援システムについて、その動作を説明する。教師は教室１の教師端末で操作を行う。
【０１１５】
図１０における教室１の教師端末２１の操作画面（図４参照）において、オールコールアイコン２５１を教師が操作すると、教師端末２１よりＬＡＮケーブル１０５及びネットワーク装置５０を介して制御信号Ｃ（ｔ１，ｔ２，…，ｔＮ，ｓ１，…，ｓｎ）が音声通信制御装置４０に送信される。これにより、教室１の音声通信制御装置４０では、図３（Ａ）における教師端末ｔ１音声入力に接続された音声入力スイッチＳＷｔ１−ｔ２、ＳＷｔ１−ｔ３、ＳＷｔ１−ｓ１、ＳＷｔ１−ｓｎが同時にＯＮとなる。そして、教師端末２１からの教師音声が教室１内の全学習者端末７１送出されるとともに、教師端末ｔ２音声出力〜教師端末ｔＮ音声出力に接続された教師端末出力端子８２〜８Ｎより教室２〜Ｎの音声通信制御装置４０に送出される。
【０１１６】
同時に教室１の教師端末２１よりＬＡＮケーブル１０５、ネットワーク装置５０及びルータ装置５１を介して別の制御信号Ｃ（ｔ２，ｓ１，…，ｓｎ）が教室２，３，…，Ｎの音声通信制御装置４０に送信される。これにより、各々の教室の音声通信制御装置４０において、教師端末ｔ２音声入力に対応する音声入力スイッチＳＷｔ２−ｓ１、ＳＷｔ２−ｓ２、…、ＳＷｔ２−ｓｎが同時にＯＮとなる。そして、各教室において教師端末入力端子９２より教師端末ｔ２音声入力に入力された教室１からの教師音声が当該教室内の全学習者端末７１に送出され、教師音声を全教室の全学習者端末７１へ送出することができる。
【０１１７】
なお、ここでは全教室の全学習者へ教師音声を送出することを例にとって説明したが、各教室へ送出する制御信号Ｃの第２項以降を適宜変更することにより、任意教室の１ないし複数の学習者に限定して教師音声を送出することも可能である。
【０１１８】
また、図１０における教室１の教師端末２１の操作画面（図４参照）において、教室Ｘａの学習者端末Ｙａ及び教室Ｘｂの学習者端末Ｙｂの両者に指定学習者マークを付与した状態でモニタアイコン２５２を操作すると、教室１の教師端末２１よりＬＡＮケーブル１０５及びネットワーク装置５０及び必要に応じてルータ装置５１を介して、教室１の音声通信制御装置４０に対し制御信号Ｃ（ｔＸａ，ｔ１）；Ｃ（ｔＸｂ，ｔ１）が送信される。また同時に、ＬＡＮケーブル１０５、ネットワーク装置５０及びルータ装置５１を介して、教室Ｘａの音声通信制御装置４０に対し制御信号Ｃ（ｓＹａ，ｔ２）が、教室Ｘｂの音声通信制御装置４０に対し制御信号Ｃ（ｓＹｂ，ｔ２）がそれぞれ送信される。これにより、任意の教室に配置された２名の学習者の音声を教師が聴取することができる。
【０１１９】
