To provide a telephone call control device capable of improving telephone call efficiency between a car and a monitoring center in an elevator with multiple cars provided in a hoistway.SOLUTION: A telephone call control device allows a telephone call in a group consisting of the cars and a monitoring center in an elevator with multiple cars provided in a hoistway. Specifically, the telephone call control device sets all telephone call lines between each of multiple cars and the monitoring center in a connection state when it receives a prescribed command signal, and enables simultaneous telephone calls in the group by setting all telephone call lines between the multiple cars in a connection state.SELECTED DRAWING: Figure 1

    【課題】昇降路内に複数の乗りかごが設けられたエレベータにおいて、乗りかごと監視センタとの間での通話を効率化できる通話制御装置を提供する。【解決手段】通話制御装置は、昇降路内に複数の乗りかごが設けられたエレベータにおいて、当該乗りかごと監視センタとで構成されるグループ内での通話を可能にする。具体的には、通話制御装置は、所定の指令信号を受信した場合に、複数の乗りかごのそれぞれと監視センタとの間の全ての通話回線を接続状態にし、且つ、複数の乗りかごの間の全ての通話回線を接続状態にすることにより、上記グループ内での同時通話を可能にする。【選択図】図1
