Abstract

There is disclosed a display device making it possible to call effective attention in a use situation where unbalanced passenger load occurs between left and right lanes of a passenger conveyor. This display device includes a first display unit (7A) positioned on the left and a second display unit (7B) positioned on the right toward the passenger conveyor at a boarding (1), a control device (20) to control the first display unit (7A) and the second display unit (7B), and passenger detection (8A, 8B) to detect passengers stepping on the passenger conveyor. The first display unit (7A) and the second display unit (7B) display images representing information to passengers. The passengers pass between the first display unit (7A) and the second display unit (7B) and step on the passenger conveyor. The control device (20) estimates a state of congestion and a state of passengers gathering on only one lane in the passenger conveyor, based on detection signals from the passenger detection means (8A, 8B), and sets an image to be displayed by the first display unit (7A) and an image to be displayed by the second display device (7B) independently, depending on the state of congestion and the state of passengers gathering on only one lane.

First claim

The invention claimed is:

1. A passenger conveyor display device that displays information to passengers who step on a passenger conveyor, the passenger conveyor display device comprising:
a first display unit positioned on the left toward the passenger conveyor at a boarding;
a second display unit positioned on the right toward the passenger conveyor at the boarding;
a control device to control the first display unit and the second display unit; and
passenger detection means for detecting passengers stepping on the passenger conveyor,
wherein the first display unit and the second display unit display images representing information to the passengers;
the passengers pass between the first display unit and the second display unit and step on the passenger conveyor;
the control device estimates a state of congestion and a state of passengers gathering on only one lane in the passenger conveyor, based on detection signals from the passenger detection means; and
the control device sets an image to be displayed by the first display unit and an image to be displayed by the second display device independently, depending on the state of congestion and the state of passengers gathering on only one lane.

2. The passenger conveyor display device according to claim 1 ,
wherein the control device sets the same image to be displayed by the first display unit and the second display unit, depending on the state of congestion and the state of passengers gathering on only one lane; and
the control device sets different images to be displayed by the first display unit and the second display unit, depending on the state of congestion and the state of passengers gathering on only one lane.

3. The passenger conveyor display device according to claim 1 ,
wherein the control device calculates a degree of congestion and a degree to which passengers gather on only one lane in the passenger conveyor, based on the detection signals from the passenger detection means, and estimates the state of congestion and the state of passengers gathering on only one lane depending on the degree of congestion and the degree to which passengers gather on only one lane.

4. The passenger conveyor display device according to claim 3 ,
wherein the state of congestion is classified into multiple levels depending on the degree of congestion;
the state of passengers gathering on only one lane is classified into multiple levels depending on the degree to which passengers gather on only one lane;
the control device stores in advance multiple images corresponding to the multiple levels of the state of congestion and the multiple levels of the state of passengers gathering on only one lane; and
the control device selects an image to be displayed by the first display unit and an image to be displayed by the second display unit from the multiple images depending on the state of congestion and the state of passengers gathering on only one lane.

5. The passenger conveyor display device according to claim 4 ,
wherein the multiple images include an image for calling attention for leading to a use situation where passengers stop and step on left and right lanes of the passenger conveyor without gathering on only one lane.

6. The passenger conveyor display device according to claim 5 ,
wherein the multiple images include any of an image that alerts passengers that they should step on the passenger conveyor, separating into the left and right lanes; an image that alerts passengers that walking is banned on the passenger conveyor; and an image that alerts passengers not to stop at an landing of the passenger conveyor.

7. The passenger conveyor display device according to claim 1 ,
wherein the passenger detection means includes a first passenger detection sensor positioned on the left toward the passenger conveyor at the boarding and a second passenger detection sensor positioned on the right toward the passenger conveyor at the boarding.

8. The passenger conveyor display device according to claim 1 ,
wherein the first display unit is disposed on a first pole positioned on the left toward the passenger conveyor at the boarding; and
the second display unit is disposed on a second pole positioned on the right toward the passenger conveyor at the boarding.

9. The passenger conveyor display device according to claim 7 ,
wherein the first passenger detection sensor is disposed on the first pole positioned on the left toward the passenger conveyor at the boarding; and
the second passenger detection sensor is disposed on the second pole positioned on the right toward the passenger conveyor at the boarding.

10. The passenger conveyor display device according to claim 1 ,
wherein the first display unit and the second display unit are formed of liquid crystal display devices.

11. A passenger conveyor comprising multiple steps that are driven to circulate between a boarding and a landing and moving handrails that are driven in synchronization with the steps,
the passenger conveyor being equipped with a display device that displays information to passengers who step on the passenger conveyor,
the display device including:
a first display unit positioned on the left toward the passenger conveyor at the boarding;
a second display unit positioned on the right toward the passenger conveyor at the boarding;
a control device to control the first display unit and the second display unit; and
passenger detection means for detecting passengers stepping on the passenger conveyor,
wherein the first display unit and the second display unit display images representing information to the passengers;
the passengers pass between the first display unit and the second display unit and step on the passenger conveyor;
the control device estimates a state of congestion and a state of passengers gathering on only one lane in the passenger conveyor, based on detection signals from the passenger detection means; and
the control device sets an image to be displayed by the first display unit and an image to be displayed by the second display device independently, depending on the state of congestion and the state of passengers gathering on only one lane.

12. The passenger conveyor according to claim 11 ,
wherein the control device sets the same image to be displayed by the first display unit and the second display unit, depending on the state of congestion and the state of passengers gathering on only one lane; and
the control device sets different images to be displayed by the first display unit and the second display unit, depending on the state of congestion and the state of passengers gathering on only one lane.

13. The passenger conveyor according to claim 12 ,
wherein the passenger detection means includes a first passenger detection sensor positioned on the left toward the passenger conveyor at the boarding and a second passenger detection sensor positioned on the right toward the passenger conveyor at the boarding;
the first display unit and the first passenger detection sensor are disposed on a first pole positioned on the left toward the passenger conveyor at the boarding; and
the second display unit and the second passenger detection sensor are disposed on a second pole positioned on the right toward the passenger conveyor at the boarding.
