FIG. 2 is a plan view showing the arrangement of the display unit, push buttons, and the like of the hall indicator lamp device. This embodiment is an embodiment in which the present invention is applied to a hall operation panel (HIB) with a car position indicator lamp installed at an elevator hall.

  On the surface of the face plate 21 of the hall operation panel 20, a car position indicator lamp 24 as a display means and push buttons 25 and 26 for car call are arranged. As shown in FIG. 2, the car position indicator lamp 24 displays the position of the car with numerals and displays the direction of operation with an arrow during operation of the elevator.

  Further, the car position indicator lamp 24 displays, for example, “inspection” in order to inform the user that the inspection work is being performed as shown in FIG. 3 during the elevator maintenance inspection work. It has come to be.

  The hall operation panel 20 provided with such a car position indicator lamp 24 is installed in the elevator hall on each floor as shown in FIG. In FIG. 1, in order to distinguish the hall operation panels 20 on each floor from each other, a reference letter is attached with a lower case letter suffix. Among these, the hall operation panel 20a is a hall operation panel installed on the top floor where the machine room is located. The hall operation panel 20b is installed on the lower floor, and the hall operation panel 20c, ... is further installed on the lower floor.

  A control panel 10 is installed in the machine room of the elevator. The control panel 10 is usually supplied with power from a commercial power supply 11 via a power supply circuit 12. Each hall operation panel 20 is connected to the control panel 10 by a cable 15 so as to transmit signals and supply power.

  In addition, the control panel 10 is provided with a battery 14 as a backup power source in preparation for an emergency power failure. The battery 14 is a spare power source for the control panel 10 and is connected to the hall operation panels 20a, 20b, 20c,... On each floor via the spare wiring 16, and is connected to the car position indicator lamps 24a, 24b, 24c,. Electric power necessary for operation can be supplied.

  In the present embodiment, an in-check switch (switch means) 22 for opening and closing the spare wiring 16 that is fed from the battery 14 is disposed inside the hall operation panel 20a in the hall on the top floor.

  The in-check display switch 22 supplies power from the battery 14 to the car position indicator lamps 24a, 24b, 24,... Even when the power of the control panel 11 is turned off during maintenance and inspection of the elevator. It is a switch that makes it happen.

Next, the operation during the maintenance and inspection work of the elevator hall indicator lamp device according to the present embodiment will be described with reference to the flowchart of FIG.
First, when the elevator maintenance and inspection work is started (step S10), it is necessary to inform the passenger that the elevator maintenance and inspection work is being performed.
Therefore, when the elevator is switched from the operation mode to the inspection mode at the start of the maintenance inspection work, a command is sent from the control panel 10 to the hall operation panels 20a, 20b, 20c,... On each floor, and all the car position indicator lights 24a, 24b,. In 24c,..., The display of the car position during the normal operation is switched to a character display such as “under inspection” (step S11). In this way, at the time of maintenance inspection work, “inspection” is displayed on the car position indicator lamps 24a, 24b, 24c,... On the hall operation panels 20a, 20b, 20c,.

  In parallel with this, the in-inspection display switch 22 is turned on in the hall operation panel 20a on the top floor (step S12).
