Description

[Technical field]

[0001] The present disclosure relates to a display device for a passenger conveyor. [Background technology]

[0002] The passenger conveyor described in Patent Document 1 is equipped with two sensors for detecting passengers near the middle inclined portion of the passenger conveyor. In this passenger conveyor, the two sensors detect the moving speed of the passenger on the passenger conveyor, and the passenger's movement is detected by comparing the rated speed of the passenger conveyor with the moving speed of the passenger. If it is determined that the passenger is running up or down, a warning announcement is made to the passenger. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-188236 A Summary of the Invention [Problem to be solved by the invention]

[0004] The passenger conveyor of Patent Document 1 aims to suppress passengers from running up or down the passenger conveyor by playing a caution announcement. However, when detecting the moving speed of passengers using a pair of sensors as in Patent Document 1, there is a risk of erroneous measurement of the moving speed of passengers due to erroneous detection of the movements of multiple passengers as the movements of one person. In addition, it is difficult to know which passenger the caution announcement is directed to, and it is possible that the passenger who is the target of the announcement will not notice the caution announcement. Even if a passenger notices the caution announcement, it is possible that the passenger will not stop moving such as running up or down. It is considered that the control of playing a caution announcement in this way is not very effective in suppressing passengers from walking on the passenger conveyor.

[0005] In view of the above problems, the present disclosure provides a display device for a passenger conveyor that is improved to more effectively prevent passengers from walking inside the passenger conveyor. [Means for solving the problem]

[0006] The display device for a passenger conveyor according to the present disclosure comprises a first projection means for projecting an image that reduces the visibility of a demarcation line provided on the outer periphery of the tread of each of a number of steps arranged in the moving path of the passenger conveyor, and if the passenger conveyor is divided along the moving direction into a boarding and alighting section including one or more steps on the boarding and alighting side of the passenger conveyor, and an intermediate section sandwiched between the boarding and alighting sections, the projection area of ​​the image that reduces visibility by the first projection means includes the surface of the step located in the intermediate section and the surface of the portion located in the intermediate section of the skirt guard provided on both sides of the width of the multiple steps. For example, the image that reduces visibility may be an image in a color similar to the color of the demarcation line. Alternatively, the display device of the passenger conveyor may include a detection means for detecting the number of passengers using the passenger conveyor and the boarding positions of the passengers on the moving passageway, and the first projection means may project an image that reduces visibility when at least one of the number of passengers on the left side and the number of passengers on the right side of a center line along the moving direction of the moving passageway is less than a first reference value.

[0007] Alternatively, the display device for a passenger conveyor according to the present disclosure includes a fourth projection means for projecting a demarcation line onto the surface of the tread of a step located in the boarding / alighting section, when the passenger conveyor having a plurality of steps arranged in a moving passage is divided along the moving direction into a boarding / alighting section including one or more steps on the boarding / alighting side of the passenger conveyor, and an intermediate section sandwiched between the boarding / alighting sections. Effect of the Invention

[0008] According to the display device of the passenger conveyor of the present disclosure, the visibility of the demarcation lines of the steps other than the steps near the entrance and exit of the passenger conveyor, i.e., the steps located in the middle part, can be reduced, or the demarcation lines can be made not to be displayed on the surface of the steps located in the middle part. Therefore, the boundaries of the steps in the middle part of the passenger conveyor can be made difficult to distinguish, and thus the movement of passengers on the moving path of the passenger conveyor can be suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals, and the description thereof will be simplified or omitted.

[0011] Embodiment 1 Fig. 1 is a schematic diagram showing the overall configuration of a passenger conveyor and a display device according to the first embodiment. In the example of Fig. 1, the passenger conveyor 100 is an escalator. As shown in Fig. 1, the passenger conveyor 100 has a plurality of steps 10. A landing floor 20 at an upper floor entrance of the passenger conveyor 100 and a landing floor 20 at a lower floor entrance of the passenger conveyor 100 are connected by a moving passage along which the plurality of steps 10 move. In the following embodiments, the left and right of the passenger conveyor 100 refer to the left and right in the traveling direction of the steps 10, that is, both ends in the width direction perpendicular to the moving direction, unless otherwise specified.

[0012] The steps 10 are connected in an endless manner and are provided so as to be able to move cyclically along the moving passage. Each of the steps 10 comprises a footboard 11 and a riser 12. Both ends in the width direction of the footboard 11 and the riser 12 are supported by a pair of brackets (not shown).

[0013] Although not shown in FIG. 1, a demarcation line (see reference numeral 11A in FIG. 2) is formed on the outer periphery of the surface of the step board 11 to enhance the visibility of the step board 11. The demarcation line is a line painted in a color different from the color of the surface of the step board 11. The color of the demarcation line is yellow, for example. The demarcation line may be formed by attaching a resin part of a molding color different from that of the step board 11 to the outer periphery of the step board 11.

[0014] A pair of balustrades 13 are installed on both sides of the width of the step 10 along the moving direction of the step 10. A skirt guard 14 is disposed on the lower part of each of the balustrades 13. The skirt guard 14 has a comb skirt disposed near the upper and lower landing floors 20, respectively, and a skirt guard panel disposed along the longitudinal direction between the upper and lower comb skirts.

[0015] In the following description, the portions of the passenger conveyor 100 near the upper and lower landing floors 20 are referred to as the boarding / alighting section 101, and the intermediate portion between the upper and lower boarding / alighting sections 101 is referred to as the inclined section 102. The boarding / alighting section 101 and the inclined section 102 are areas that divide the passenger conveyor 100 perpendicularly to the direction of movement. There is no limitation on the boundary between the boarding / alighting section 101 and the inclined section 102, but the boarding / alighting section 101 is assumed to include at least the upper and lower landing floors 20 and the step 10 adjacent to the landing floor 20. For example, the inclination angle of the balustrade 13 is constant, and the area where the step 10 moves in a straight line may be referred to as the inclined section 102, and the areas on both sides of the inclined section 102 may be referred to as the boarding / alighting section 101.

[0016] The passenger conveyor 100 is equipped with a sensor 1, a camera 2, an inclined section projector 3, and a control device (see FIG. 3). For the sake of explanation, in FIG. 1, the sensor 1, the camera 2, and the inclined section projector 3 installed on the right side of the paper are shown in a see-through state from the right side of the passenger conveyor 100. In addition, in FIG. 1, the sensing range of the sensor 1, the shooting range of the camera 2, and the projection area of ​​the inclined section projector 3 are each shown by dashed lines.

[0017] The sensor 1 is disposed near the upper and lower landing floors 20, such as a com skirt. The sensor 1 detects passengers who pass through the detection range, thereby detecting passengers who board the passenger conveyor 100 or passengers who disembark from the passenger conveyor 100. The output of the sensor 1 is transmitted to a control device 4, which will be described later. FIG. 1 shows an example in which a total of four sensors 1 are disposed on the left and right skirt guards 14 of the upper and lower landing floors 20, respectively, but there is no limit to the number of sensors 1 to be installed. It is sufficient that an appropriate number of sensors 1 are installed according to the detection range so that the number of passengers boarding the passenger conveyor 100 and the number of passengers disembarking from the passenger conveyor 100 can be monitored.

[0018] The cameras 2 are installed near the landing floor 20 of the skirt guard 14, for example, near the end of the com skirt or skirt guard panel. The shooting range of the cameras 2 includes at least the entire width direction from the left end to the right end of the step 10 at the installation location of the cameras 2. Although an example is shown in FIG. 2 in which a total of two cameras 2 are arranged near the upper and lower landing floors 20, respectively, there is no limit to the number of cameras 2 to be installed. It is sufficient that an appropriate number of cameras 2 are installed so that the cameras 2 can capture images of the entire width direction near the upper and lower landing entrances.

[0019] Fig. 2 is a diagram showing the vicinity of the installation location of the inclined section projector of the passenger conveyor. Fig. 2 shows the installation location of the inclined section projector 3 with the skirt guard panel 14A near the inclined section projector 3 removed. The inclined section projectors 3 are arranged at regular intervals inside the skirt guard panel 14A of the inclined section 102. As shown in Fig. 2, smoked glass 14B is installed on the surface of the skirt guard 14 at the location where the inclined section projector 3 is arranged.

[0020] The inclined portion projector 3 is capable of projecting an image toward the surface of the step 10. There is no limit to the number of inclined portion projectors 3 to be installed, and an appropriate number of inclined portion projectors 3 are arranged in consideration of their projection areas. That is, it is sufficient that an appropriate number of inclined portion projectors 3 are arranged so that all the inclined portion projectors 3 cover at least the entire surface of the step 10 of the inclined portion 102 of the passenger conveyor 100 as a projection area, and so that the overlapping portion of the projection areas of the inclined portion projectors 3 is small or the projection areas are adjacent to each other.

[0021] Fig. 3 is a block diagram showing the configuration of a display device of a passenger conveyor. As shown in Fig. 3, the display device of the passenger conveyor 100 includes a sensor 1, a camera 2, an inclined section projector 3, and a control device 4. The control device 4 controls a motor 15 for driving the passenger conveyor 100. The control device 4 also controls the projection of an image by the inclined section projector 3.

[0022] The sensor 1, the camera 2, and the control device 4 function as detection means for detecting the number of passengers and their boarding positions on the passenger conveyor 100. The sensor 1 and the control device 4, and the camera 2 and the control device 4 are connected by wire or wirelessly, respectively. The output of the sensor 1 and the output of the camera 2 are input to the control device 4.

[0023] The sensor 1 detects passengers by sensing the passage of passengers within its detection range, and transmits the detection result to the control device 4. Based on the detection result of the sensor 1, the control device 4 calculates the number of passengers boarding the passenger conveyor 100 and the number of passengers disembarking.

[0024] The camera 2 inputs data of the captured image to the control device 4. The image captured by the camera 2 may be a still image or a video. In the case of a still image, the camera 2 captures an image, for example, at regular intervals or in response to a capture request from the control device 4, and transmits the image to the control device 4. Based on the image data transmitted from the camera 2, the control device 4 monitors the boarding positions of passengers who have boarded the passenger conveyor 100, i.e., the passenger layout.

[0025] The control device 4 detects whether the passenger is on the left or right side of the passageway as the boarding position of the passenger. In the following embodiment, the boarding position of the passenger is determined to be the left side when the passenger is on the left side of the traveling direction, and the right side when the passenger is on the right side, with the center line of the passageway parallel to the traveling direction as the boundary.

[0026] The inclined portion projector 3 and the control device 4 are connected by wire or wirelessly and function as a first projection means for projecting an image that reduces the visibility of the demarcation line. The inclined portion projector 3 projects an image onto its projection area.

[0027] Fig. 4 is a diagram showing an example of a location where an image is projected by the inclined section projector 3. In the example of Fig. 4, the balustrade 13 and skirt guard 14 on one side and their internal structure are omitted, and mainly the balustrade 13 and skirt guard 14 on the other side, the step 10, and the landing floor 20 on the upper floor side are shown. For clarity, the outer perimeter of the step 10 is shown in bold.

[0028] 4, the inclined portion projector 3 projects images 3A and 3B that reduce the visibility of the demarcation line onto and around the demarcation line among the surfaces of the tread 11, riser 12, and skirt guard panel 14A of the step 10 located on the inclined portion 102. By reducing the visibility of the demarcation line with the image from the inclined portion projector 3, it is possible to make the staircase shape of the step 10 on the inclined portion 102 less visible.

[0029] The projected images 3A and 3B are, for example, images of a similar color to the color of the demarcation line. By projecting images 3A and 3B of a similar color to the color of the demarcation line on and around the demarcation line, the demarcation line of step 10 of inclined portion 102 can be visually recognized. Note that, as long as the visibility of the demarcation line can be reduced, there is no particular limitation on the similarity between the color of the demarcation line and the color of the projected image. Also, the images 3A and 3B may be still images that appear relatively still, or may be moving images.

[0030] Next, the control operation by the control device 4 will be described. The control device 4 is a control device for the passenger conveyor 100, and also functions as a control device for controlling the inclined section projector 3. In this embodiment, the control device 4 controls the operating speed of the passenger conveyor 100 and the projection operation by the inclined section projector 3.

[0031] Specifically, the control device 4 changes the operating speed of the passenger conveyor 100 depending on the congestion state of the passenger conveyor 100. Fig. 5 is a timing chart showing an example of control of the operating speed of the passenger conveyor by the control device. In Fig. 5, the horizontal axis indicates time t [sec] and the vertical axis indicates speed V [m / min]. As shown in Fig. 5, the control device 4 performs rated operation with the operating speed set to the rated speed during busy times, which are times when there are many passengers and the passenger conveyor 100 is crowded. Also, during off-peak times, which are times when there are relatively few passengers, performs eco-operation with the operating speed set to a speed slower than the rated speed.

[0032] The congested and off-peak times may be set in advance in the control device 4. Alternatively, the control device 4 may acquire the congestion state of the passenger conveyor 100 and control the operating speed. In this case, the control device 4 calculates the congestion state of the passenger conveyor 100 from the number of passengers calculated based on the output of the sensor 1. Then, depending on the calculated congestion state, it is determined whether the current time is a congested time or an off-peak time, and the operating speed is controlled according to the determination result.

[0033] The operating speed of the passenger conveyor 100 is changed by the control of the control device 4 depending on the timing of operation start, busy times, quiet times, operation stop, and transitional periods between these. The image that reduces the visibility of the demarcation line needs to be projected in accordance with the position of the demarcation line on the step 10. Therefore, the control device 4 detects the moving speed of the step 10 of the passenger conveyor 100 from the rotation speed of the motor 15, and changes the images 3A and 3B projected by the inclined section projector 3 so that they move in synchronization with the movement of the step 10.

[0034] The control device 4 also controls the start and stop of the projection operation of the image by the inclined part projector 3. Specifically, the control device 4 calculates the number of passengers on the entire passenger conveyor 100 and the number of passengers on the left and right sides based on the output of the sensor 1 and the camera 2. Then, it is determined whether or not the following conditions are met: (i) the number of passengers is less than a predetermined number, and (ii) at least one of the number of passengers on the left side and the number of passengers on the right side is greater than a first reference value. If it is determined that both of the conditions (i) and (ii) are met, it can be determined that there is enough space in the passageway for passengers to walk and move. Therefore, in this case, the control device 4 executes projection by the inclined part projector 3 to project an image that reduces the visibility of the demarcation line.

[0035] The predetermined number and the first reference value are reference values ​​for determining whether there is sufficient space for passengers to walk and move, and are stored in advance in the control device 4. However, the determination of whether there is sufficient space for passengers to walk and move is not limited to being based on whether the conditions (i) and (ii) are satisfied. For example, a configuration may be adopted in which it is determined that there is sufficient space for passengers to walk and move when the above condition (ii) is satisfied. Also, instead of the number of passengers, the occupancy rate of the passenger conveyor 100 or the like may be used as a parameter for the determination.

[0036] By the above control, when the passageway of the passenger conveyor 100 is in an environment where passengers can walk, it is possible to reduce the visibility of the demarcation line of the step 10 on the inclined portion 102. This makes it difficult to distinguish the staircase shape of the step 10, and effectively inhibits passengers from walking.

[0037] The step 10 located at the boarding / alighting area 101 is outside the range of the projection area of ​​the inclined section projector 3. Therefore, even if there is space in the passageway where passengers can walk, an image that reduces the visibility of the demarcation line is not projected onto the step 10 located at the boarding / alighting area 101. Therefore, passengers can reliably recognize the demarcation line of the step 10 near the landing floor 20 where passengers need to walk.

[0038] In this embodiment, a case has been described in which the inclined section projector 3 projects an image that reduces the visibility of the demarcation line, making it difficult to see the tread 11 of the step 10. In addition to this, the display device may be configured to monitor passengers running up or down, and warn passengers when running up or down is detected.

[0039] In this case, the display device of the passenger conveyor 100 has a function as a speed detection means for detecting the moving speed of the passengers, and a function as a third projection means for projecting an image for calling attention.

[0040] Specifically, a speed sensor that detects the moving speed of passengers is installed, for example, near the skirt guard panel 14A of the inclined portion 102 of the passenger conveyor 100. The control device 4 detects the moving speed of passengers based on the output of the speed sensor.

[0041] The inclined section projector 3 and the control device 4 also function as a third projection means for projecting an attention-calling image to call the attention of passengers. When the detected moving speed of a passenger is faster than a reference speed, the control device 4 projects an attention-calling image in synchronization with the movement of the passenger to call attention. Here, an example of the attention-calling image is an image that lights up the surroundings of a moving passenger in a warning color such as red. This emphasizes the moving passenger and makes him stand out from the surroundings, making the passenger hesitate to walk and informing surrounding passengers that there is a pedestrian.

[0042] Furthermore, the display device of the passenger conveyor 100 may be configured to include a warning means for issuing a warning to the moving passengers to call their attention. The warning may be a warning sound issued to the moving passengers or a voice guidance to call their attention. This makes it possible to call the attention of the moving passengers or passengers around the moving passengers.

[0043] Here, the reference speed is a reference value for determining whether a passenger is moving along the passageway, and is stored in advance in the control device 4. The reference speed may be a variable that is set based on the moving speed of the passenger conveyor 100.

[0044] Embodiment 2 6 is a schematic diagram showing the configuration of a passenger conveyor according to embodiment 2. The passenger conveyor 200 of embodiment 2 has the same configuration as the passenger conveyor 100 of embodiment 1, except that it has a landing projector 7 at the landing entrance.

[0045] 6 shows the state of the passenger conveyor 200 as seen in the direction of movement of the steps 10 from the landing floor 20 side on the upper floor. The display device of the passenger conveyor 200 according to the second embodiment includes a landing projector 7 in addition to the sensor 1, the camera 2, and the inclined section projector 3.

[0046] As shown in Fig. 6, the landing projector 7 is installed in the inlet guard 14C portion near the landing entrance of each floor. The landing projector 7 includes the landing floor 20 in its projection area. Note that, although the example of Fig. 6 shows an example in which a pair of landing projectors 7 are installed on the left and right of the landing entrance of each floor, there is no limit to the number of landing projectors 7 that can be installed. It is sufficient that an appropriate number of landing projectors 7 are installed so that the portion of the landing floor 20 onto which the image should be projected is appropriately included in the projection area 7A.

[0047] The image projected by the hall projector 7 is a guidance image for guiding passengers. The guidance image is an image for guiding passengers at the hall entrance to the left or right side of the passageway to which the passengers are to be guided. The guidance image may be a still image or a video. Specifically, for example, the guidance image shows a flow line according to the architectural layout. In this case, the flow line may be shown by arranging footprints along the flow line as shown in FIG. 6. Alternatively, the guidance image may be an arrow showing the flow line, or an image of a person moving ahead along the flow line. In addition, the guidance image may be, for example, an image that prevents passengers from entering the side to which the passengers are not to be guided, either the left or right side. Examples of such guidance images include an image of a virtual gate that prevents passengers from entering, an image of a wall that prevents intrusion, and an image of a person standing still at the hall entrance to which the passengers are not to be guided.

[0048] The hall projector 7 is connected to the control device 4 by wire or wirelessly, and functions as a second projection means together with the control device 4. The start and stop of image projection by the hall projector 7 is controlled by the control device 4. When the control device 4 determines from the output of the sensor 1 and the camera 2 that the passenger layout is biased to the left or right side of the passageway, it displays a guidance image that guides passengers to the side opposite the biased side, or a guidance image that prevents passengers from entering the biased side.

[0049] More specifically, the control device 4 projects a guidance image from the hall projector 7 when the number of passengers detected by the sensor 1 is less than the second reference value and the difference between the number of passengers on the right side and the number of passengers on the left side is greater than the third reference value. Here, the second and third reference values ​​are thresholds for determining whether or not to adjust the bias of the passenger boarding positions by projecting the guidance image, and are values ​​that are set in advance in the control device 4. However, the determination of whether or not to project the guidance image is not limited to this, and for example, when a certain difference occurs in the number of passengers on the right side and the left side, the guidance image may be displayed regardless of the total number of passengers. Also, a configuration may be adopted in which a guidance image that guides passengers to the side with fewer passengers on the right side and the left side is always displayed. Also, instead of the number of passengers, the occupancy rate of the passenger conveyor 200 may be used as a parameter for determination.

[0050] In the first and second embodiments, the boarding position of the passenger is detected by the camera 2 installed at the landing. However, the method of detecting the boarding position is not limited to this. Fig. 7 is a diagram for explaining a method of checking the position of the passenger layout by the control device 4. Fig. 7 shows the moving path of the inclined portion 102 of the passenger conveyor 100 or 200 as viewed from above in a direction perpendicular to the moving path.

[0051] In the example shown in FIG. 7, a pair of inclined portion sensors 8 are installed on the skirt guard 14 of the inclined portion 102 of the passenger conveyor 100 or 200. The inclined portion sensors 8 are reflective sensors. When both the left and right inclined portion sensors 8 are reacting, the control device 4 can detect that passenger A is riding on both the left and right sides, and when only the left or right inclined portion sensor 8 is reacting, the control device 4 can detect that passenger A is riding on only one side, either the left or right side. For example, the control device 4 can grasp the current passenger layout to some extent based on the detection results by the inclined portion sensors 8 during a certain period of time.

[0052] When the control device 4 determines from the grasped passenger layout that there is a space on one side of the passageway where passengers can walk and move, it can project an image that reduces the visibility of the demarcation line from the inclined section projector 3. Alternatively, when the control device 4 determines from the grasped passenger layout that passenger A is biased to the left or right side, it displays a guidance image that guides the passenger to the right or left side. In this way, by using the inclined section sensor 8, the passenger layout can be grasped in a simpler manner without analyzing the image from the camera 2.

[0053] Embodiment 3 Fig. 8 is a schematic diagram showing the configuration of a passenger conveyor according to embodiment 3. In the example of Fig. 8, the balustrade 13 and skirt guard 14 on one side and their internal structure are omitted, and mainly the balustrade 13 and skirt guard 14 on the other side, the step 10, and the landing floor 20 on the upper floor side are shown. The passenger conveyor 300 of embodiment 3 has the same configuration as the passenger conveyor 100 or 200 of embodiment 1 or 2, except that the skirt guard 14 of the inclined portion 102 is provided with a skirt guard brush 16 and a speaker 9.

[0054] The skirt guard brush 16 of the passenger conveyor 300 according to the third embodiment is disposed so as to hide the demarcation line on the skirt guard 14 side of the tread 11 when viewed from above along the surface of the skirt guard 14 on the step 10 side. The skirt guard brush 16 is intended to make passenger A aware that he / she is approaching the gap between the skirt guard 14 and the tread 11 by touching it.

[0055] The passenger conveyor 300 is also provided with a speaker 9 as a warning means near the skirt guard brush 16 of the skirt guard 14. The speaker 9 is connected to the control device 4 by wire or wirelessly, and the issuance and stopping of a warning sound by the speaker 9 is controlled by the control device 4. When contact of passenger A with the skirt guard brush 16 is detected, the control device 4 causes the speaker 9 to issue an alarm. The alarm here may be a warning sound or a voice-based caution guidance.

[0056] As described above, in this embodiment, the demarcation line is hidden by the skirt guard brush 16 of the inclined portion 102, making it difficult to identify the shape of the step 10 on the inclined portion 102. This makes it possible to suppress passengers from walking on the inclined portion 102. In addition, when passenger A touches the skirt guard brush 16, a warning is issued to the passenger by the speaker 9, thereby warning passenger A that he or she is approaching the gap between the skirt guard 14 and the step 11.

[0057] Embodiment 4 9 is a schematic diagram showing the configuration of a passenger conveyor according to this embodiment. A passenger conveyor 400 according to this embodiment has the same configuration as any of the passenger conveyors 100, 200, and 300 according to the first to third embodiments, except that the tread 11 of the step 10 does not have a demarcation line, that the passenger conveyor 400 is equipped with a hall projector 17, and that the image projected by the inclined section projector 3 is different.

[0058] Landing projectors 17 are attached to the skirt guards 14 of the upper and lower landing areas 101. There is no limit to the number of landing projectors 17 to be installed, but an appropriate number of them are installed so that the projection area includes at least the entire surface of the tread 11 of the step 10 located in the landing area 101. The landing projector 17 projects a demarcation line 17A by image onto the surface of the tread 11 in the portion between the end of the inclined portion 102 and the landing floor 20.

[0059] The hall projector 17 and the control device 4 function as a fourth projection means. The hall projector 17 is connected to the control device 4 by wire or wirelessly, and the image projected by the hall projector 17 and the start or stop of the projection of the image are controlled by the control device 4.

[0060] As described in the first embodiment, the control device 4 controls the moving speed of the steps 10 depending on the congestion state of the passenger conveyor 400. The control device 4 calculates the moving speed of the steps 10 based on the rotation speed of the motor 15. In accordance with the calculated moving speed, the control device 4 controls the image projected by the hall projector 17 so that the demarcation line 17A is projected at an appropriate position on the outer periphery of the moving tread 11.

[0061] The inclined section projector 3 and the control device 4 function as a fifth projection means. The inclined section projector 3 projects a freely set image 3C onto the surface of the step 10 located on the inclined section 102 of the passenger conveyor 400. The image to be projected may be, for example, an image of nature such as a forest. By using an image of a forest, it is possible to create a space that makes one feel as if they are in a forest. If the image is a moving image, the image may be changed in accordance with the speed of the passenger conveyor 400.

[0062] In the case where the step 11 does not have a demarcation line on its surface as in this embodiment, it is not necessary to project an image that reduces the visibility of the demarcation line to discourage walking on the inclined portion 102 of the passenger conveyor 400. On the other hand, in the boarding and alighting portion 101 near the landing floor 20, a demarcation line is projected onto the step 11, so that passengers can reliably see the boundary of the step 10 when boarding and alighting from the passenger conveyor 400.

[0063] In addition, by projecting images on the inclined portion 102 of the passenger conveyor 400, it is possible to create a comfortable space while preventing people from walking on the inclined portion 102.

[0064] In the above embodiments, the passenger conveyors 100, 200, 300, and 400 are escalators. However, the passenger conveyor in the present disclosure may be, for example, a moving walkway.

[0065] Also, the control device 4 has been described as a case where the control device that controls the operation of the passenger conveyor 100 has a function of controlling the start and stop of image projection by the inclined section projector 3 and the hall projector 7 or 17. However, the control device that controls the operation of the passenger conveyor 100 and the control device that controls the projection of images by the inclined section projector 3 and the hall projectors 7 and 17 may be configured as independent control devices different from each other. Also, the control devices of the inclined section projector 3 and the hall projectors 7 and 17 may be different independent control devices.

[0066] In addition, the functions realized by the components such as the control device 4 described in the present embodiment may be implemented using circuits including general-purpose processors, application-specific processors, integrated circuits, ASICs (Application Specific Integrated Circuits), CPUs (Central Processing Units), conventional circuits, or combinations thereof, programmed to realize the described functions. A processor is considered to be a circuit because it includes transistors and other circuits. A processor may execute a program stored in a memory. In addition, the circuits, units, and means in the embodiments are hardware that is programmed to realize the described functions or hardware that executes the described functions. The hardware may be any hardware disclosed in the embodiments, or any hardware that is programmed to realize the described functions or known to execute the described functions. In the case where the hardware is a processor that can be considered as a kind of circuit, the circuit, means, or unit is a combination of hardware and software used to configure the hardware and / or processor.

[0067] Although the preferred embodiments have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the claims.
