DOOR LOCK TAMPER-RESISTANT DEVICE AND DOOR LOCK SYSTEM
To prevent unauthorized unlocking of a door more reliably than before.SOLUTION: A door lock tamper-resistant device 40 of the present invention is connected via a door D to a face authentication terminal 10 including a switch element 12 having a common terminal COM, a normally-closed terminal NC and a normally-open terminal NO, and a processing unit 11 that switches the connection destination of the common terminal COM between a normally-closed terminal NC and a normally-open terminal NO according to an authentication result: and is configured to control a locking state of the door D according to changes in the combination of a potential of an input terminal a, which is connected to the normally-open terminal NO via the door D, and a potential of an input terminal b, which is connected to the normally- closed terminal NC via the door D.SELECTED DRAWING: Figure 1
【課題】従来よりも確実に、扉の不正解錠を防止できるようにする。【解決手段】本発明による扉ロック不正解除防止装置４０は、共通端子ＣＯＭ、常閉端子ＮＣ、常開端子ＮＯを有するスイッチ素子１２と、認証結果に応じて、共通端子ＣＯＭの接続先を常閉端子ＮＣ及び常開端子ＮＯの間で切り替える処理部１１と、を有する顔認証端末１０に扉Ｄを介して接続され、扉Ｄを介して常開端子ＮＯに接続される入力端子ａの電位と、扉Ｄを介して常閉端子ＮＣに接続される入力端子ｂの電位との組み合わせの変化に応じて、扉Ｄのロック状態を制御するよう構成される。【選択図】図１
