Referring to FIG. 1, in the present invention, a lower photodetector 2 for detecting passengers boarding a car is provided on one side of the entrance / exit of the car at a position 50 cm from the floor surface of the car, and is located on one side of the entrance / exit of the car. An upper photodetector 2 for detecting passengers who also board the car is attached to the upper part (for example, at a position 1 m above the floor of the car). On the other hand, the elevator control device is provided with a photodetector 4 which receives the detection signals of the upper photodetector 1 and the lower photodetector 2 and operates by these detection signals.

In addition, the signal output from the above-described photodetector 4 is input to the elevator control device, and an adult boarding detection signal by the upper photodetector 1 output from the upper photodetector 1 is input. A determination / detection device 7 is provided to determine whether there is a signal from the lower photodetector 2 that is a boarding signal for an infant or a physically handicapped person.

Further, the signal output from the photodetector 4 is also input to the timer 6, and in the timer 6, the determination detection circuit is provided after a predetermined time has elapsed from the input time of the signal input from the photodetector 4. The elapsed time is output to 7. Next, the operation of the elevator of the present invention will be described with reference to the flowchart of FIG.

First, in step 11, when the car call button at the hall is pressed, the elevator is called, and in the next step 12, the car door is opened, as in the conventional case. Next, when the passenger gets in from the opened door, the upper and lower photoelectric detectors operate, but in step 13, whether only the lower photoelectric detector operates from the signals input from the upper and lower photoelectric detectors. The determination / detection device 7 determines whether or not.

If only the lower photoelectric detector operates, a signal is output to the door control device 9 to keep the door open, and the process proceeds to the next step 14. In step 14, a signal indicating that the fixed time has elapsed is input from the timer 6 to the determination detection device 7, and the determination detection device 7 outputs a signal to the alarm device 5 to activate the alarm device 5. And proceed to the next step 15.

In step 15, the call detection device 3 detects whether or not there is a car call. If a car call is issued, the process proceeds to the next step 16 and the door control device 9 opens the car door. To be closed. When the car door is closed,
Proceeding to the next step 17, normal operation is started, and the car is controlled by the operation control device 8 to be lifted up and down on the called floor and landed.
