description	To solve the problem in which since unidirectional transmission means such as a data diode completely blocks communication from an external network to an internal network, information on the external network that is desired to be used in the internal network cannot be acquired.SOLUTION: A network system includes information transmission means for transmitting information from an external network to an internal network by converting the information into an image or a sound without connecting the internal network with the external network.SELECTED DRAWING: Figure 1 【課題】データダイオードなどの一方向送信手段は外部ネットワークから内部ネットワークに向けた通信を完全に遮断するため、内部ネットワークで使用したい外部ネットワークの情報を取得することができない。【解決手段】内部ネットワークと外部ネットワークとを接続することなく、外部ネットワークからの情報を、画像または音に変換することにより、内部ネットワークに伝達する情報伝達手段を備えた。【選択図】図１
