    • PROBLEM TO BE SOLVED: To provide a visitor authentication device capable of efficiently authenticating a plurality of visitors.
      SOLUTION: A visitor authentication device 70 includes: a representative image acquisition part 71 which acquires a representative image relating to a representative of visitors on the basis of an imaged result of a camera 15 provided at an entrance of a building; a visitor image acquisition part 72 which acquires visitor images relating to visitors on the basis of an imaged result of a camera 40 provided in the front of an elevator 3 in the building; an image determination part 75 which compares the representative image and the visitor images with each other to determine whether the representative is included in the visitors; and an elevator movement propriety determination part 77 which permits movement of the elevator 3 when determining the representative to be included among the visitors and inhibits movement of the elevator 3 when determining the representative to be not included among the visitors.

    • PROBLEM TO BE SOLVED: To reduce power consumption of an interphone or at the time of communication between an interphone and a monitoring center device by using battery power. SOLUTION: An interphone I or a telecommunication device 1 of an elevator which permits communication between the interphone 1 and a monitoring center device 15 is provided with an interphone call detecting part 2 detecting a call from the interphone 1, a circuit call detecting part 3 detecting a call from the monitoring center device 15, and the first relay 8 connecting a battery power source 10 with the telecommunication device 1 by outputted signals from the detecting parts 2, 3. A communication control part 4 controlling communication of the interphone 1, a circuit control part 5 controlling communication between the interphone 1 and the monitoring center device 15, and the second relay 9 actuated by a command signal disconnecting the battery power source 10 from the telecommunication device 1 upon completing communication are provided.

    • PURPOSE: To reduce the cost without placing a load on a microcomputer for an annunciator controller. CONSTITUTION: The control microcomputer 7 of a control part 3, the communication circuit 16, display circuit 23, and input circuit 25 of an annunciator part 5 are mutually connected. Further, the control microcomputer 7 and a timing generating circuit 27, and the timing circuit 27 and display circuit 23 are connected to each other. If a display factor is generated, display data are outputted from the control microcomputer 7 to the communication circuit 16 and further sent to the display circuit 23. The control microcomputer 27 outputs a display data synchronizing signal to the timing generating circuit 27, which outputs a time-division control signal to the display circuit 23 to perform display control. Therefore, the control microcomputer 7 does not control the annunciator part 5 directly, so no load is placed on the control microcomputer 7.

    • PURPOSE:To eliminate a problem causing the overflow of a telephone line connected to a monitoring center by outputting a delayed state notice from the central processing circuit according to the damage condition of an elevator when an elevator state signal and a disaster detecting signal are input into the central processing circuit at the occurrence of a wide area disaster. CONSTITUTION:When a wide area disaster such as earthquake, etc., occurs, a detector 8 detects it, and its detected signal is input from the detector 8 into an input circuit 4 together with the output signals for the operating conditions of an elevator 3. In a central processing circuit 5, the damage condition of the elevator 3 is diagnosed, and abnormality notice conditions are judged. When it is judged that instantaneous notice must be issued, a state notice is transmitted from a central processing circuit 5 to a monitoring center 2 through a communication circuit 6 and a telephone line. On the other hand, when it is judged that delay notice must be issued, the state notice is input from the central processing circuit 5 to a delay circuit 7 and, after a specified time has been collapsed, the state notice is transmitted to the monitoring center 2 through the communication circuit 6 and the telephone line.
