PROBLEM TO BE SOLVED: To allow a medical staff who has responded to call to intuitively identify a medical ward from which the call has been output, without operating a corridor light uselessly.SOLUTION: When a recovery operation part 25 of a master unit 20 is operated while a corridor light notification part 13 is in operation, the corridor light notification part 13 is stopped after a prescribed time passes and, when a corridor light recovery operation part 14 of the corridor light 10 to which a cordless handset 1 that has called is connected is operated, the corridor light notification part 13 is immediately stopped, and therefore notification of the corridor light notification part 13 is performed even when the medical staff who has operated the recovery operation part 25 is supposed to come near to the medical ward, and the medical staff intuitively identifies the medical ward from which the call has been output. Whereas, when the corridor light recovery operation part 14 is operated, the corridor light notification part 13 is immediately stopped, however since the corridor light recovery operation part 14 is near the medical ward from which the call has been output, the immediate stop of the corridor light notification part 13 does not disturb the medical staff to identify the medical ward from which the call has been output and the corridor light notification part 13 is not uselessly operated.COPYRIGHT: (C)2012,JPO&INPIT【課題】廊下灯を無駄に動作させず、応答した医療従事者が呼び出しを行った病室を直感的に特定できるようにする。【解決手段】廊下灯報知部13が動作している状態で、親機20の復旧操作部25が操作された場合に、所定時間経過後に廊下灯報知部13を停止させ、呼び出しを行った子機1が接続されている廊下灯10の廊下灯復旧操作部14が操作された場合に、直ちに廊下灯報知部13を停止させるので、復旧操作部25の操作を行った医療従事者が病室近傍に駆けつけるであろう時点でも廊下灯報知部13の報知が行われており、医療従事者は呼び出しを行った病室を直感的に特定することができる。一方、廊下灯復旧操作部14が操作された場合には、廊下灯報知部13が直ちに停止するが、廊下灯復旧操作部14が呼び出しを行った病室近傍にあるため、医療従事者が呼び出しを行った病室を特定する妨げにはならず、無駄に廊下灯報知部13を動作させない。【選択図】図1
