The lower side of the balustrade panel 33 is supported by the truss, and the handrail 32 is supported in a circularly movable manner. A pair of handrails 32 and balustrade panels 33 are provided along the aisle on the left and right sides of the aisle.

The entrance 4 is provided with a floor plate 40 at both the entrance 4A and the entrance 4B. The floor plate 40 constitutes the floor of the entrance 4 and constitutes the end portion (start end portion and end portion) of the passage. The tip edge of the floor plate 40 is in contact with the upper surface of the endless transport body 30 and defines a boundary between the transport portion 3 and the entrance / exit 4.

The floor surface is provided with an ultraviolet irradiation device 5 in a predetermined area. In the present embodiment, the predetermined area is a rectangular area having the same width as the passage.

As shown in FIG. 6, other configurations of the ultraviolet irradiation device 5 are the same as the configuration of the ultraviolet irradiation device 5 according to the first embodiment. The description of this similar configuration will be omitted as it is the same as the description in the first embodiment.

As described above, the escalator according to the present embodiment also exhibits the same effects as those of the elevator according to the first embodiment.

The entrance 4 may be provided with a pole (not shown). A pair of poles are provided on the left and right sides of the aisle, and are installed at the ends (starting and ending) of the aisle. Passengers enter the entrance 4A through the pair of poles, pass between the pair of poles, and exit from the exit 4B. The pole is equipped with a human detection sensor. The human detection sensor detects passengers entering the entrance 4A and detects passengers leaving the exit 4B, and is a form of detection means for detecting passengers. There are two types of human detection sensors, for example. One person detection sensor is an area sensor. Another person detection sensor is a line sensor. By combining these sensors, it is possible to accurately grasp the number of passengers entering the entrance 4A and the number of passengers leaving the entrance 4B. Then, as a type of escalator, when there are no passengers (passengers are not detected by the person detection sensor), the transport unit 3 is stopped, and when there are passengers (passengers are detected by the person detection sensor), the transport unit 3 There is a so-called automatic escalator where operation is started. By providing the entrance 4 with a person detection sensor, as an example, in the ultraviolet irradiation device 5, the operation is stopped (turned off) while there are no passengers, and when the person detection sensor detects a passenger, the operation (lights up) is performed. If a passenger is not detected after a certain period of time has passed after the operation, the operation can be stopped again.

Further, the entrance / exit 4 may be provided with a guidance display unit (not shown) that indicates that ultraviolet sterilization is being carried out and that a person is requested to stay for a certain period of time for sterilization. The guide display unit is a known display means such as a sticker, a label, a plate, etc. attached to the surface of the pole. Alternatively, the guidance display unit may include, or instead of, a visual display unit using a display provided on a pole or the like, or a voice display unit using a speaker provided on or near the pole. It can also be adopted. In these cases, the display may be performed each time the person detection sensor at the entrance 4 (pole) detects a passenger. According to these configurations, a waiting state for a predetermined time occurs after the passenger who tries to get into the transport unit 3 is sterilized and then before the passenger who tries to get into the transport unit 3 is sterilized. This inevitably separates the passengers from each other, resulting in a passenger transport mode in which the distance between the passengers is widened. Therefore, it is possible to effectively prevent the concentration of passengers on the escalator and realize a social distance (social distance). However, if the same display is performed on the guidance display unit of the exit 4B, passengers may stay at the exit 4B, which is not preferable in terms of safety. Therefore, it is preferable that the control unit enables switching between the operation mode and the non-operation mode of the guidance display unit, and the guidance display unit of the exit 4B is inoperable.
