Description

[Technical field]

[0001] The present invention relates to a passenger conveyor system. [Background technology]

[0002] Conventionally, passenger conveyors that present information to passengers are known. For example, Patent Document 1 discloses an information presentation device for a passenger conveyor that displays information for suppressing the movement of passengers based on the state of the passengers on one or more display devices provided on the inside of the passenger conveyor. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2022-28444 Summary of the Invention [Problem to be solved by the invention]

[0004] However, passengers often ride on the passenger conveyor while facing the direction of travel. Therefore, even if information is displayed on the inside of the passenger conveyor, it is difficult for the passengers to notice it. One aspect of the present invention aims to realize a passenger conveyor system that can display an image that is more reliably visible to passengers riding on the passenger conveyor. [Means for solving the problem]

[0005] In order to solve the above problems, a passenger conveyor system according to one embodiment of the present invention includes an aerial projection display unit that displays an aerial projection image in an estimated passage space through which at least a part of the body of a passenger riding on the passenger conveyor may pass, and a display control unit that controls the display on the aerial projection display unit.

[0006] According to the above configuration, the aerial projection image is displayed in an estimated passage space through which at least a part of the body of a passenger riding on the passenger conveyor is likely to pass. This makes it easier for the aerial projection image to be within the field of view of the passenger. As a result, it is possible to realize a passenger conveyor system that can display an image that is more reliably visible to the passengers.

[0007] In a passenger conveyor system according to another aspect of the present invention, the projection position, projection direction, and field of view of the aerial projection image may be set so that the area in which the entire aerial projection image is visible includes all specified positions in the estimated passing space whose distance to the center of the aerial projection image is a first specified distance.

[0008] According to the above configuration, all of the predetermined positions in the estimated passage space that are the first predetermined distance from the center of the aerial projection image are included in the area where the entire aerial projection image is visible. As a result, the aerial projection image can be viewed in the estimated passage space that is further away from the aerial projection image than the predetermined positions including the predetermined positions, so that the aerial projection image can be presented to passengers in a desired space by appropriately setting the predetermined positions, for example.

[0009] In another aspect of the passenger conveyor system of the present invention, an information acquisition unit may be provided that acquires location information including a current location of the passenger, and the display control unit may control the display on the aerial projection display unit based on the current location of the passenger.

[0010] According to the above configuration, the display of the aerial projection image by the aerial projection display unit is controlled based on the current position of the passenger, so that the aerial projection image can be displayed according to the position of the passenger.

[0011] In a passenger conveyor system according to another aspect of the present invention, the display control unit may hide the aerial projection image or change the display position of the aerial projection image to outside the estimated passing space when the distance between the aerial projection image and the passenger on the near side of the aerial projection image in the direction of travel of the passenger conveyor becomes within a second predetermined distance.

[0012] According to the above configuration, for example, by setting the second specified distance near the aerial projection image, it is possible to allow passengers to view the aerial projection image for as long as possible while preventing the passengers from passing through the aerial projection image, thereby reducing the discomfort felt by passengers when passing through the aerial projection image.

[0013] In a passenger conveyor system according to another aspect of the present invention, the display control unit may hide the aerial projection image after a predetermined time has elapsed when the distance between the aerial projection image and the passenger on the near side in the direction of travel of the passenger conveyor becomes within a third predetermined distance, or may change the display position of the aerial projection image to outside the estimated passing space.

[0014] According to the above configuration, for example, by setting the time for the moving steps to move the third predetermined distance as a predetermined time, it is possible to prevent passengers who are standing still instead of walking from passing through the aerial projection image, and to allow passengers who are walking along the moving steps to pass through the aerial projection image by continuing to display the aerial projection image. Therefore, it is possible to reduce discomfort for passengers who are riding in a preferred manner (passengers who are standing still instead of walking) and to suppress the desire to walk for passengers who are riding in an unpreferable manner (passengers who are walking).

[0015] In another aspect of the passenger conveyor system of the present invention, the passenger conveyor system may further include an information acquisition unit that acquires a congestion degree indicating the degree of congestion of the passenger conveyor, and the display control unit may control the display on the aerial projection display unit based on the congestion degree.

[0016] According to the above configuration, the display by the aerial projection display unit is controlled according to the degree of congestion of the passenger conveyor, so that an aerial projection image can be displayed according to the degree of congestion.

[0017] In the passenger conveyor system according to another aspect of the present invention, the display control unit may not display the aerial projection image when the congestion degree is equal to or greater than a first predetermined value.

[0018] According to the above configuration, when the congestion level is equal to or higher than a first predetermined value, the aerial projection image is not displayed. This makes it possible to prevent a situation in which the display of the aerial projection image is repeatedly turned on and off due to a high congestion level, for example, when the aerial projection image is controlled not to be displayed when a passenger is detected near the aerial projection image.

[0019] In a passenger conveyor system according to another aspect of the present invention, the aerial projection display units may be provided in plurality so that a plurality of the aerial projection images are displayed along the direction of travel of the passenger conveyor, and the display control unit may control the display and non-display of the aerial projection images on the aerial projection display units so that, when the congestion degree is lower than a second predetermined value, the aerial projection images are displayed at intervals wider than the intervals between the aerial projection images when all of the plurality of aerial projection display units display the aerial projection images.

[0020] When the degree of congestion is low, passengers can recognize the aerial projection image even if the distance between the passengers and the aerial projection image is great, so that passengers can recognize the aerial projection image for a sufficient period of time even if the number of aerial projection images is reduced. According to the above configuration, the aerial projection images can be thinned out when the degree of congestion is low, so that power consumption can be reduced while passengers can recognize the aerial projection image for a sufficient period of time.

[0021] A passenger conveyor system according to another aspect of the present invention includes an information acquisition unit that acquires images of the passengers, and a passenger determination unit that determines, based on the images, whether or not there is an inappropriate passenger who is riding on the passenger conveyor in an undesirable manner, and the display control unit, if there is an inappropriate passenger, displays the aerial projection image on the side of the passenger conveyor in the direction of travel of the inappropriate passenger, and may continue to display the aerial projection image at least until the inappropriate passenger passes the aerial projection image.

[0022] According to the above configuration, for the inappropriate passenger, the aerial projection image can be displayed so that the inappropriate passenger passes through the aerial projection image. This makes it possible to make the inappropriate passenger feel uncomfortable and to suppress the inappropriate passenger from using the passenger conveyor.

[0023] In another aspect of the passenger conveyor system of the present invention, the aerial projection display unit may include a first aerial projection display unit that displays the aerial projection image in an area of ​​the estimated passing space on the left side of the traveling direction of the passenger conveyor, and a second aerial projection display unit that displays the aerial projection image in an area of ​​the estimated passing space on the right side of the traveling direction.

[0024] According to the above configuration, even if the passenger conveyor has moving steps on which two people can stand side by side, it is possible to display an aerial projection image to each person on the left and right. Therefore, it is possible to provide a display that is more suited to each individual passenger. Effect of the Invention

[0025] According to one aspect of the present invention, it is possible to realize a passenger conveyor system that can display an image that is more reliably visible to passengers riding on the passenger conveyor. [Brief description of the drawings]

[0027] [Embodiment 1] An embodiment of the present invention will be described in detail below. However, the following description is an example of a passenger conveyor system 1 according to the present invention, and the technical scope of the present invention is not limited to the illustrated example.

[0028] <Overview of passenger conveyor system> The passenger conveyor system 1 is a system that displays an aerial projection image G1 in the air toward passengers on a passenger conveyor 40. Fig. 1 is a diagram showing an example of a functional block diagram of the passenger conveyor system 1 including a display device 10 according to a first embodiment of the present invention. Fig. 2 is a schematic diagram showing an example of the configuration of the passenger conveyor system 1.

[0029] As shown in Figures 1 and 2, the passenger conveyor system 1 is designed to display an aerial projection image G1 in an estimated passage space S (see Figure 2) through which at least a part of the body of a passenger riding on the passenger conveyor 40 is likely to pass, thereby ensuring that the image to be presented to passengers is more reliably visible to passengers on the passenger conveyor 40.

[0030] <Passenger conveyor system> As shown in Fig. 1, the passenger conveyor system 1 includes a display device 10, a passenger conveyor control device 30, a passenger conveyor 40, a camera 50, and a sensor 60. The passenger conveyor 40 is a conveyor that automatically transports passengers up or down floors, such as an escalator. The passenger conveyor 40 is not limited to the above, and may be a horizontal conveyor that transports passengers horizontally on the same floor, such as a moving walkway.

[0031] The passenger conveyor control device 30 controls the operation of the passenger conveyor 40. The passenger conveyor control device 30 includes a control unit 31 and a memory unit 32. The control unit 31 comprehensively controls each unit of the passenger conveyor control device 30. The functions of the control unit 31 may be realized by a CPU (Central Processing Unit) executing a program stored in the memory unit 32. The memory unit 32 stores various programs executed by the passenger conveyor control device 30 and data used by the programs.

[0032] The camera 50 captures images of the passenger conveyor 40 and its passengers. The images captured by the camera 50 are transmitted to the display device 10. The sensor 60 detects the passage of a person at a predetermined position. The sensor 60 may be, for example, a photoelectric sensor.

[0033] The sensor 60 is disposed on the near side of the aerial projection image G1 in the traveling direction D1 of the passenger conveyor 40 to detect that the distance between the aerial projection image G1 and the passenger is within a second predetermined distance. The sensor 60 is disposed on the near side of the aerial projection image G1 in the traveling direction D1 of the passenger conveyor 40 to detect that the distance between the aerial projection image G1 and the passenger is within a third predetermined distance. The sensor 60 may be disposed for each aerial projection image G1, or one sensor may be disposed at the boarding entrance of the passenger conveyor 40, and the second predetermined distance or the third predetermined distance may be calculated from the speed of the moving step 43 (see FIG. 2).

[0034] (display device) The display device 10 is a device that displays an aerial projection image G1. The display device 10 includes a control unit 11, a storage unit 12, and an aerial projection display unit 20.

[0035] The control unit 11 comprehensively controls each unit of the display device 10. The functions of the control unit 11 may be realized by a CPU executing a program stored in the storage unit 12. The storage unit 12 stores various programs executed by the control unit 11 and data used by the programs. The storage unit 12 also stores aerial projection image information. The units included in the control unit 11 and the aerial projection image information will be described in detail later.

[0036] (Aerial projection display section) The aerial projection display unit 20 displays an aerial projection image G1 in an estimated passage space S through which at least a part of the body of a passenger riding on the passenger conveyor 40 may pass, based on the control of the display control unit 112. A plurality of aerial projection display units 20 are provided so that a plurality of aerial projection images G1 are displayed along the traveling direction D1 of the passenger conveyor 40. Not limited to the above, the number of aerial projection display units 20 may be one.

[0037] The estimated passing space S is set arbitrarily, and for example, as shown in Fig. 2, the estimated passing space S includes the space above the moving step 43 of the passenger conveyor 40. The estimated passing space S includes the boarding entrance 41 to the disembarking entrance 42, and the height from the moving step 43 can be set to 2m or less, and the width in the traveling direction D1 can be set to a distance from the handrails on both sides toward the outside to 0.5m or less. The height of the estimated passing space S is desirably set so that the face of a standing passenger is included in the moving step 43. The width of the estimated passing space S is desirably set so that the face of a passenger is included when the passenger steps over the handrail.

[0038] The aerial projection image G1 is displayed in the estimated passage space S through which at least a part of the body of a passenger riding on such a passenger conveyor 40 may pass. Therefore, the aerial projection image G1 is likely to be within the field of view of the passenger.

[0039] The aerial projection display unit 20 displays an image (video) in the air by utilizing reflection of light. As shown in FIG. 1, the aerial projection display unit 20 includes an original image display device 201 and an optical element 202. FIG. 3 is a diagram for explaining the structure of the aerial projection display unit 20. As shown in FIG. 3, the original image display device 201 has a display surface 201a, and displays an image to be displayed as an aerial projection image G1 on the display surface 201a. The display control unit 112 controls the display of the aerial projection image G1 by controlling the display of the display surface 201a of the original image display device 201. The original image display device 201 is not particularly limited as long as it can display an image or video on the display surface 201a, and for example, a liquid crystal display can be used.

[0040] The optical element 202 forms an image in the air that is the same as the image displayed by the original image display device 201, and displays an aerial projection image G1 in the air. As shown in FIG. 3, the optical element 202 passes light emitted from the original image display device 201 through a light-transmitting member having a special structure in the optical element 202, thereby concentrating the light emitted from the original image display device 201 at a predetermined spatial position on the opposite side of the optical element 202 from the original image display device 201, and forms an image at the predetermined spatial position that is the same as the image displayed by the original image display device 201. In other words, the aerial projection display unit 20 is a display device that displays an aerial projection image G1 in the air within the estimated passing area S by concentrating light emitted from each position of the original image display device 201 at the corresponding spatial positions via the optical element 202. As a result, the aerial projection display unit 20 can display the aerial projection image G1 in the air without dispersing a medium for realizing an aerial display, such as mist, in the space.

[0041] In addition, since the aerial projection display unit 20 projects an image into the air, no physical configuration such as a screen or display board for image display is required at the image display location. Therefore, the aerial projection display unit 20 can display an image in the estimated passing space S while avoiding the risk of passengers coming into contact with the physical configuration for image display in the estimated passing space S.

[0042] Fig. 4 is a diagram showing an example of the arrangement of the aerial projection display unit 20. 4001 in Fig. 4 shows one example of the arrangement of the aerial projection display unit 20, and 4002 in Fig. 4 shows another example of the arrangement of the aerial projection display unit 20. As shown in 4001 in Fig. 4, the optical element 202 may be arranged along a wall W arranged along the passenger conveyor 40, or as shown in 4002 in Fig. 4, the optical element 202 may be arranged at an angle to the wall W.

[0043] The original image display device 201 is disposed at an angle to the optical element 202, and when the angle between the optical element 202 and the original image display device 201 is θ, the aerial projection image G1 is displayed at a position where the angle between the optical element 202 and the aerial projection image G1 is θ. The angle θ can be, for example, greater than 0° and equal to or less than 90°. The material of the optical element 202 is not particularly limited, and may be, for example, glass or resin.

[0044] In this way, by providing the aerial projection display unit 20 inside the wall W, it is possible to realize the aerial projection display without the need to provide a separate space for providing the aerial projection display unit 20. Furthermore, without being limited to the above, the aerial projection display unit 20 may be provided on the ceiling, and the aerial projection image G1 may be displayed from above the passenger conveyor 40.

[0045] (Aerial projection image) 5 is a diagram illustrating the viewing angle θ1 of the aerial projection image G1 of the aerial projection display unit 20. As shown in FIG. 5, the aerial projection image G1 has a viewing angle θ1. The aerial projection image G1 is visible only within the range of the viewing angle θ1. The viewing angle θ1 is, for example, about 30° to 60°. By adjusting the size and angle of the optical element 202, the distance from the source image display device 201 to the optical element 202, and the like, it is possible to change the size, viewing angle θ1, and angle θ2 between the surface of the optical element 202 and the viewing angle center of the aerial projection image G1 of the aerial projection image G1.

[0046] As shown in Figure 2, the projection position, projection direction, and viewing angle θ1 of the aerial projection image G1 are set so that the area R1 in which the entire aerial projection image G1 is visible includes all of the specified positions P1 in the estimated passing space S where the distance to the center C1 of the aerial projection image G1 is a first specified distance L1.

[0047] The region R1 in which the entire aerial projection image G1 is visible is the region where the viewing angle θ1 at each point on the aerial projection image G1 overlaps. When a passenger in region R1 looks at the aerial projection image G1, the entire aerial projection image G1 can be seen. Region R1 can be set to a desired range by adjusting the projection position, projection direction, and viewing angle θ1 of the aerial projection image G1.

[0048] Therefore, for example, a predetermined position P1 is set in the estimated passing space S, and the projection position, projection direction, and viewing angle θ1 of the aerial projection image G1 are adjusted to set an area R1 so as to include the entire predetermined position P1, so that the aerial projection image G1 can be presented to passengers in a desired space. Note that since the area R1 is set to include the entire predetermined position P1, the entire aerial projection image G1 can be viewed even in the estimated passing space S which is further away from the aerial projection image G1 than the predetermined position P1 and includes the predetermined position P1.

[0049] 6001, 6002, and 6003 in FIG. 6 are diagrams showing examples of the arrangement of the aerial projection image G1. As shown in 6001 in FIG. 6, the aerial projection image G1 may be displayed so that the aerial projection image G1 is located at the position of the passenger's face when the passenger passes through the aerial projection image G1. In addition, the aerial projection image G1 is displayed in a substantially vertical direction in 6001 in FIG. 6, but as shown in 6002 in FIG. 6, the aerial projection image G1 may be displayed tilted from the vertical direction in accordance with the inclination of the passenger conveyor 40. For example, the aerial projection image G1 may be displayed tilted from the vertical direction toward the front side of the traveling direction D1 so as to be substantially perpendicular to the inclination of the passenger conveyor 40.

[0050] 6, the aerial projection image G1 may be displayed at the feet of passengers. In this case, the aerial projection image G1 may be displayed tilted from the vertical toward the traveling side of the traveling direction D1 so that the image can be easily viewed by passengers. Displaying the aerial projection image G1 at a low position can be achieved, for example, by embedding the aerial projection display unit 20 in a glass surface below a handrail.

[0051] The size of the aerial projection image G1 is not particularly limited, as long as at least a portion of the aerial projection image G1 is included in the estimated passing space S.

[0052] (Display device control unit) 1, the control unit 11 includes an information acquisition unit 111, a display control unit 112, a congestion degree calculation unit 113, and a passenger determination unit 114. The information acquisition unit 111 acquires operation information of the passenger conveyor 40 from the passenger conveyor control device 30.

[0053] Furthermore, the information acquisition unit 111 acquires images of passengers and position information including the current positions of the passengers. The information acquisition unit 111 may acquire the passenger position information from the sensor 60, or may acquire the passenger position information by performing image analysis on the images captured by the camera 50. Furthermore, the information acquisition unit 111 acquires a congestion degree indicating the degree of congestion on the passenger conveyor 40. The information acquisition unit 111 acquires the congestion degree from the congestion degree calculation unit 113. The information acquisition unit 111 may acquire a congestion degree calculated outside the display device 10.

[0054] The congestion degree calculation unit 113 calculates the congestion degree of the passenger conveyor 40. The congestion degree calculation unit 113 outputs the calculated congestion degree to the information acquisition unit 111. The congestion degree is calculated, for example, by the actual number of passengers relative to the capacity of the passenger conveyor 40. The congestion degree calculation unit 113 may calculate the congestion degree based on, for example, an image captured by the camera 50, or may calculate the congestion degree based on the load on a drive device of the passenger conveyor 40. In addition, the congestion degree calculation unit 113 may calculate the congestion degree based on the number of passengers detected within a predetermined period of time by a sensor 60 provided at the boarding entrance 41 of the passenger conveyor 40.

[0055] The passenger determination unit 114 determines the presence or absence of an inappropriate passenger, who is a passenger riding on the passenger conveyor 40 in an undesirable manner, based on the captured image (image). The passenger determination unit 114 determines the presence or absence of an inappropriate passenger, for example, by performing image analysis on the image captured by the camera 50. The passenger determination unit 114 outputs the determination result to the display control unit 112. Examples of inappropriate passengers include passengers walking on the passenger conveyor 40, passengers not holding onto the handrails, passengers leaning over the handrails, and passengers letting go of their carry bags.

[0056] (Display control unit) The display control unit 112 controls the display on the aerial projection display unit 20 based on the passenger's current position. Specifically, when the distance between the aerial projection image G1 and the passenger on the near side in the traveling direction of the passenger conveyor 40 with respect to the aerial projection image G1 falls within a second predetermined distance, the display control unit 112 hides the aerial projection image G1 or changes the display position of the aerial projection image G1 to outside the estimated passing space S. The second predetermined distance may be set to the shortest distance (distinct visibility distance) at which the aerial projection image G1 can be clearly seen without eye strain, and may be set to, for example, 25 cm.

[0057] When the aerial projection image G1 is hidden or the display position of the aerial projection image G1 is changed from within the estimated passing space S to outside the estimated passing space S, the passenger's body does not pass through the aerial projection image G1. Therefore, for example, by setting the second predetermined distance to be near the aerial projection image G1, it is possible to prevent the passenger from passing through the aerial projection image G1 while allowing the passenger to view the aerial projection image G1 for as long as possible, thereby reducing the discomfort felt by the passenger when passing through the aerial projection image G1. Instead of changing the display position of the aerial projection image G1 from within the estimated passing space S to outside the estimated passing space S, the display control unit 112 may reduce the size of the aerial projection image G1 even within the estimated passing space S and display it at a position that does not pass through the passenger's body.

[0058] After hiding the aerial projection image G1, the display control unit 112 may redisplay the aerial projection image G1 when the passenger has passed the position where the aerial projection image G1 was displayed. After changing the display position of the aerial projection image G1 from inside the estimated passing space S to outside the estimated passing space S, the display control unit 112 may change the display position of the aerial projection image G1 from outside the estimated passing space S to inside the estimated passing space S when the passenger has passed the position where the aerial projection image G1 was originally displayed. This makes it possible to quickly restore the display of the aerial projection image G1, and the image to be presented to the passengers can be more reliably viewed by the passengers on the passenger conveyor 40.

[0059] After hiding the aerial projection image G1, the display control unit 112 may redisplay the aerial projection image G1 when the passenger has passed through the imaging area R2 (see 4001 in FIG. 4). After changing the display position of the aerial projection image G1 from inside the estimated passing space S to outside the estimated passing space S, the display control unit 112 may change the display position of the aerial projection image G1 from outside the estimated passing space S to inside the estimated passing space S when the passenger has passed through the imaging area R2. The imaging area R2 is an area surrounded by the optical element 202 and the aerial projection image G1, and the presence of a person in the imaging area R2 interferes with the display (imaging) of the aerial projection image G1. Therefore, by performing redisplay or the like as described above, the aerial projection image G1 can be displayed satisfactorily.

[0060] Furthermore, when there is no subsequent passenger, the display control unit 112 may hide the aerial projection image G1 until a passenger boards the passenger conveyor 40. Note that the display control unit 112 may always display the aerial projection image G1 rather than hiding it, depending on the display content of the aerial projection image G1.

[0061] (Variation 1) When the distance between the aerial projection image G1 and the passenger on the near side of the traveling direction D1 of the passenger conveyor 40 becomes within a third predetermined distance, the display control unit 112 may hide the aerial projection image G1 after a predetermined time has elapsed, or may change the display position of the aerial projection image G1 to outside the estimated passing space S.

[0062] As a result, for example, by setting the time it takes for the moving step 43 to move the third predetermined distance as a predetermined time, it is possible to prevent passengers who are standing still instead of walking from passing through the aerial projection image G1, and to allow passengers who are walking in the moving step 43 to pass through the aerial projection image G1 by continuing to display the aerial projection image G1. Therefore, it is possible to reduce discomfort for passengers who are riding in a preferred manner (passengers who are standing still instead of walking) and to suppress the desire to walk for passengers who are riding in an unpreferable manner (passengers who are walking).

[0063] (Variation 2) The display control unit 112 may control the display on the aerial projection display unit 20 based on the congestion degree. Specifically, the display control unit 112 may hide the aerial projection image G1 when the congestion degree is equal to or greater than a first predetermined value.

[0064] As a result, when the congestion level is equal to or higher than the first predetermined value, the aerial projection image G1 is not displayed. Therefore, for example, when a passenger is detected near the aerial projection image G1, the aerial projection image G1 is prevented from being repeatedly turned on and off due to a high congestion level.

[0065] Furthermore, when the congestion degree is lower than a second predetermined value, the display control unit 112 may control the display and non-display of the aerial projection images G1 of the aerial projection display unit 20 so that the aerial projection images G1 are displayed at intervals wider than the intervals between the aerial projection images G1 when all the aerial projection display units 20 display the aerial projection images G1. In other words, when the congestion degree is lower than the second predetermined value, the display control unit 112 may thin out some of the aerial projection images G1 among the multiple aerial projection images G1 displayed on the passenger conveyor 40.

[0066] Fig. 7 is a diagram showing another example of the arrangement of the aerial projection images G1. 7001 in Fig. 7 shows a state in which all of the multiple aerial projection images G1 on the passenger conveyor 40 are displayed, and 7002 in Fig. 7 shows a state in which some of the multiple aerial projection images G1 on the passenger conveyor 40 have been thinned out.

[0067] When the congestion level is lower than a second predetermined value, the display control unit 112 thins out the multiple aerial projection images G1 by hiding some of the multiple aerial projection images G1 displayed on the passenger conveyor 40, and displays the aerial projection images G1 at intervals wider than the intervals between the aerial projection images G1 when all of the multiple aerial projection images G1 are displayed.

[0068] When the congestion level is low, passengers can recognize the aerial projection image G1 even if they are far away from the aerial projection image G1, so passengers can recognize the aerial projection image G1 for a sufficient period of time even if the number of aerial projection images G1 is reduced. Therefore, by thinning out the aerial projection images G1 when the congestion level is low, power consumption can be reduced while passengers can recognize the aerial projection image G1 for a sufficient period of time.

[0069] (Variation 3) The display control unit 112 may control the display on the aerial projection display unit 20 based on the presence or absence of an inappropriate riding passenger. Specifically, when the passenger determination unit 114 determines that there is an inappropriate riding passenger, the display control unit 112 may display the aerial projection image G1 on the side of the inappropriate riding passenger in the traveling direction of the passenger conveyor 40, and may continue to display the aerial projection image G1 at least until the inappropriate riding passenger passes the aerial projection image G1.

[0070] As a result, for passengers boarding inappropriately, the aerial projection image G1 can be displayed so that the passengers boarding inappropriately pass through the aerial projection image G1, which makes the passengers boarding inappropriately feel uncomfortable and inhibits them from using the passenger conveyor 40.

[0071] In addition, the display control unit 112 may continue to display the aerial projection image G1 even after the inappropriate passenger has passed through the aerial projection image G1, or may hide the aerial projection image G1 when the inappropriate passenger has passed through the aerial projection image G1.

[0072] (Example of an aerial projection image) Fig. 8 is a diagram showing a display example of an aerial projection image G1. The aerial projection image G1 shown in Fig. 8 is stored as aerial projection image information in the storage unit 12. The aerial projection image G1 may be an image showing an advertisement as shown in information E1, or an image of an arrow showing the driving direction as shown in information E2. It may also be an image combining characters and an illustration showing a warning as shown in information E3, or an image showing information about the floor where the exit 42 is located as shown in information E4.

[0073] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals are given to members having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0074] 9 is a diagram showing an example of a functional block diagram of a passenger conveyor system 1A according to embodiment 2 of the present invention. The passenger conveyor system 1A is different from the passenger conveyor system 1 in that the aerial projection display unit 20A of the display device 10A includes a first aerial projection display unit 20X and a second aerial projection display unit 20Y, but the other configurations are the same.

[0075] The first aerial projection display unit 20X and the second aerial projection display unit 20Y each have a configuration similar to that of the aerial projection display unit 20. The first aerial projection display unit 20X and the second aerial projection display unit 20Y differ in their arrangement positions and the display position of the aerial projection image G1.

[0076] Fig. 10 is a diagram showing an example of the arrangement of the aerial projection display unit 20A of the passenger conveyor system 1A. As shown in Fig. 10, the first aerial projection display unit 20X displays an aerial projection image G1X in an area of ​​the estimated passing space S on the left side of the traveling direction D1 of the passenger conveyor 40. The second aerial projection display unit 20Y displays an aerial projection image G1Y in an area of ​​the estimated passing space S on the right side of the traveling direction D1. Therefore, the first aerial projection display unit 20X is arranged on the left side of the traveling direction D1 of the passenger conveyor 40, and the second aerial projection display unit 20Y is arranged on the right side of the traveling direction D1.

[0077] As a result, for example, if the passenger conveyor 40 has moving steps 43 on which two people can stand side by side, the aerial projection image G1 (aerial projection image G1X or aerial projection image G1Y) can be displayed to each person on the left and right. Therefore, it is possible to perform a display that is more suited to each individual passenger.

[0078] 10, the first aerial projection display unit 20X and the second aerial projection display unit 20Y are arranged at the same position in the traveling direction D1, and the aerial projection image G1X and the aerial projection image G1Y are displayed at the same position in the traveling direction D1, but this is not limited to the above. The first aerial projection display unit 20X and the second aerial projection display unit 20Y may be arranged at different positions in the traveling direction D1, and the aerial projection image G1X and the aerial projection image G1Y may be displayed at different positions in the traveling direction D1. The passenger conveyor system 1A may also be configured to divide the estimated passing space S into several sections and display a different aerial projection image G1 for each section.

[0079] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. The technical scope of the present invention also includes embodiments obtained by appropriately combining the technical means disclosed in the different embodiments. Furthermore, new technical features can be formed by combining the technical means disclosed in the respective embodiments. [Explanation of symbols]
