Next, the operation of the above-described first embodiment will be described with reference to FIGS. 2 and 3. FIG. 2 is a flowchart showing the operation of the first embodiment of the present invention. Also, FIG.
FIG. 6 is a flowchart showing a claw detection operation according to the first embodiment of the present invention.

As a condition, when all of the following matters are satisfied for a certain period of time, the in-car illumination lamp 6 is turned off.

[1] The call by the car operation panel is not registered. [2] The call by the call button at the hall on each floor must not be registered. [3] The basket is stopped. [4] The car has stopped at the regular stop position. [5] Passengers are not in a sick state in the basket.

The detection of the misleading state of the above item 5 is as follows.
As shown in the flow chart of FIG. 3 described later, it is assumed that the car is not run and the door is not opened for one minute or more even though the call is registered by the car operation panel.

In steps 21 to 25, the above five conditions are satisfied, and in steps 26 to 27, when the fixed time has elapsed, the in-car illumination lamp 6 is turned off. Further, in step 28, if any one of the above five conditions is not satisfied, the in-car illumination light 6 is not turned off (the automatic light-off function is disabled).

In steps 31 to 35, when the call is registered by the car operation panel and the car does not open even after traveling for 1 minute, the pick-up is detected.

The first embodiment of the present invention, as described above,
When the passenger is confined in the car, the in-car illumination lamp 6 provided in the car is not automatically turned off, and the increase in anxiety of the confined passenger is alleviated.
This is the condition that the automatic turn-off condition is blocked by detecting the occurrence of misalignment and pickling. That is, in an elevator having an in-car illumination device that automatically turns off the in-car illumination light 6, when a hall call does not occur for a certain period of time (for example, about 15 to 30 minutes), passengers are trapped in the elevator cage and the elevator is closed. When the stop is stopped, the misalignment state is detected, the automatic light-off function is canceled, and the in-car illumination lamp 6 is continuously turned on.

In other words, it is determined from the stop position information of the basket and the information of the squeeze state whether the interior illumination lamp 6 is automatically turned off, that is, it is stopped in a quiet time or when it is stopped due to a failure. When it is stopped, the automatic extinguishing function is disabled.Therefore, when a passenger becomes distracted due to a malfunction, the automatic extinguishing function operates and the inside of the car becomes dark, increasing the anxiety of passengers. There is an effect that can be solved.

Although the first embodiment described above is composed of a relay circuit, it may be composed of a CPU or the like and the automatic light-off function may be disabled by software.
