[0032] Therefore, the detection range !_ 8 of the first sensor 30 8 covers the boarding/alighting area 20 1

2 Sensor 30 Detection range of _________________________________________________________________________________ of_ of_ of which of which covers the inside of the car room 20. In this way, by installing a plurality of sensors 380 and 380 in the car 120, it is possible to widen the detectable range even with a sensor having a narrow detection range.

In the boundary area between the cab 20 and the boarding/alighting area 201, the detection range !_ 8 of the first sensor 30 8 and the detection range !_ _ of the second sensor 30 8 overlap. As a result, the double detection of the boundary area between the cab 20 and the boarding/alighting area 201 by the two sensors 30 and 30 makes it possible to improve the detection accuracy and reliability.

[0034] Note that the number of sensors 30 installed in the car 120 is not limited to one or two, and three or more sensors 30 may be installed in the car 120. Good too.
