In the case of one line for a stand, there is a construction period in which the old and new elevators are operated at the same time. The control panel of the old elevator is a relay type control panel, and the control panel of the new elevator is a microcomputer. Therefore, it is difficult to use the input / output signal of the hall button for both the old and new elevators because it is difficult to take an input / output interface. Requires a converter. It is not economical to manufacture and install this signal converter according to the specifications of the elevator each time construction is performed.

For this reason, a temporary hall button used for temporary installation until the completion of construction of all elevators is installed,
The existing hall buttons are connected to the relay-type control panel, and the temporary hall buttons are connected to the microcomputer panel so that the old and new elevators can operate simultaneously.

[0004]

The temporary work hall button is temporarily installed in the elevator hall. The signal from the temporary hall button must be pulled into the elevator hoistway by a signal cable and connected to the control panel of the elevator machine room via the hoistway.

Since there is no wiring hole for the signal cable to be drawn in the door of the elevator and the wall of the elevator hole, how to pull the signal cable into the hoistway becomes a problem. The gap between the elevator door and the three-sided frame is small and it is difficult to pull in the signal cable. Other technologies are JP-A-61
As in Japanese Patent No. 136886, an AC power supply line is used to exchange signals between devices, and a high frequency modulation signal is superimposed on the AC power supply,
A method for eliminating the need for a signal line by transmitting an elevator signal, and a hoistway as a means for transmitting display data to an in-car information display device installed in an elevator car as disclosed in JP-A-5-116871. There is a method of performing wireless data transmission by using the guide rail inside as an antenna.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a cordless temporary hole button which does not require a signal cable.

In the present invention, an arrival forecast light, an indicator, and a hall button (only the arrival forecast light is representatively shown) installed in each floor elevator hall are provided with a transmitter / receiver for performing optical transmission between the arrival forecast light and the wall surface of the elevator hall. Then, the signal cable for the transceiver is drawn into the elevator hoistway using the hole that was opened to install the arrival forecast light. Further, a transmitter / receiver for optical transmission is also installed in the temporary hall button installed in the same hall, and signals are transmitted / received at 1: N between the arrival forecast lamp and the temporary hall button.

[0008]

Function: The signal of the temporary hall button installed on each floor is coded with the floor name and the up / down calling direction, and is transmitted / received at 1: N, so that the signal can be identified without error. Further, since the call registration lamp is built in the temporary hall button, it is possible to identify the presence or absence of call registration.
