That is, the destination floor button 2 is regarded as a push button of the telephone, and the destination floor button 2 is sequentially pushed so that the number displayed on the destination floor button 2 becomes the telephone number of the designated telephone 22.

  When there is no number included in the telephone number among the numbers displayed on the destination floor button 2, the number is increased or decreased by pressing either the door open button 3 or the door close button 4.

  When confirming the input number, the door open button 3 and the door close button 4 are simultaneously pressed once. In order to cancel the input number, the door open button 3 and the door close button 4 are simultaneously pressed twice. At this time, the input telephone number is displayed on the LCD display device 7.

  In this way, when all the telephone numbers of the designated telephones 22 are input, the door open button 3 and the door close button 4 are simultaneously pressed three times. As a result, the input telephone number is confirmed, and connection from the intercom device 9 to the designated telephone device 22 becomes possible.

  In such an emergency call device for an elevator, an operation mode state in which each destination floor button 2, door open button 3 and door close button 4 operation information is input to the destination floor registration CPU 12, and each operation information is transmitted to the call function CPU 13. The state of the interface unit 15 can be switched between the dial mode state to be input, and the call function CPU 13 sets the connection destination of the intercom device 9 to the setting telephone 21 when the interface unit 15 is in the operation mode state. When the interface unit 15 is in the dial mode state, the connection destination of the interphone device 9 is specified to the designated telephone 22 based on each operation information. Even if there is no response, the car operation panel 1 is switched by the state switching by the interface unit 15. It can be used as a telephone push button type, it is possible to perform calls to specified telephone 22 specifying passengers in the car from the car. This makes it possible to make an emergency call from the car to an emergency contact (for example, home, company, hospital, etc.) more reliably.

  In addition, the network control device 14 disconnects the connection between the interphone device 9 and the telephone line network 19 when a call between the interphone device 9 and the setting telephone 21 is impossible within a predetermined time. Therefore, the call from the intercom device 9 to the setting telephone 21 can be performed again. In addition, by switching the interface unit 15 from the operation mode state to the dial mode state, it is possible to make a call to the designated telephone 22 and to make an emergency call from the car to the emergency contact more reliably.

  In addition, each destination floor button 2 for designating the destination of the car is operated in the car for inputting dial information, so the number displayed on each destination floor button 2 is set to the telephone number. It is possible to correspond to numbers, and the operation of inputting a telephone number can be easily performed. Further, since it is not necessary to newly provide a button for inputting dial information, the cost can be reduced.

  Further, since the car operation panel 1 is provided with an LCD display device 7 for displaying dial information as a telephone number, it can be operated while checking the input status of the dial information to the call function CPU 13. An input error can be prevented.
