DETAILED DESCRIPTION OF THE INVENTION

[0009] The following describes embodiments of the subject matter of the present disclosure with reference to the accompanying drawings. In each drawing, identical or corresponding parts are designated by the same reference numerals, and redundant explanations are appropriately simplified or omitted. Note that the subject matter of the present disclosure is not limited to the following embodiments, and any component of the embodiments may be modified or omitted within the scope of the gist of the present disclosure.

[0010] Embodiment 1 FIG. 1 is a side view showing an escalator as a passenger conveyor according to the first embodiment. In the figure, a truss 1 is installed between an upper floor and a lower floor. One longitudinal end of the truss 1 is hung on a structure on the upper floor as the upper end of the truss 1. The other longitudinal end of the truss 1 is hung on a structure on the lower floor as the lower end of the truss 1. The width direction of the truss 1 coincides with the horizontal direction perpendicular to the longitudinal direction of the truss 1.

[0011] An upper machine room is provided inside the upper end of the truss 1. A lower machine room is provided inside the lower end of the truss 1. The upper machine room contains an upper sprocket 2, a driving machine (not shown), and a conveyor control device (described later). The lower machine room contains a lower sprocket 3.

[0012] A plurality of steps 4 are supported on the truss 1. The steps 4 are endlessly connected by a step chain 5. The step chain 5 is wound around an upper sprocket 2 and a lower sprocket 3.

[0013] The drive machine generates a driving force that moves each step 4 in a circular motion. The conveyor control device controls the drive machine. The operation of the escalator is controlled by the conveyor control device. The upper sprocket 2 rotates by receiving the driving force from the drive machine. As the upper sprocket 2 rotates, each step 4 moves in a circular motion along an endless step path set between the upper machine room and the lower machine room.

[0014] The step path along which each step 4 moves is an endless path consisting of an outbound section, an upper reversal section, a return section, and a lower reversal section, which are connected in sequence. The upper reversal section is a path that follows the outer periphery of the upper sprocket 2. The lower reversal section is a path that follows the outer periphery of the lower sprocket 3. The outbound section and return section are paths that connect the upper reversal section to the lower reversal section. The return section is set below the outbound section. When each step 4 moves along the outbound section, passengers can board the step 4.

[0015] A pair of balustrade devices 6 are provided on the truss 1, facing each other in the width direction of the truss 1. An endless moving handrail 7 is individually provided on the periphery of each balustrade device 6. Each moving handrail 7 moves along the periphery of each balustrade device 6 in synchronization with each step 4 by the driving force of a driving machine.

[0016] Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. Each balustrade device 6 has a balustrade panel 61 and a deck device 62.

[0017] The balustrade panel 61 is a transparent glass panel that is erected on the truss 1. The balustrade panel 61 is arranged along the longitudinal direction of the truss 1. The lower part of the balustrade panel 61 is held by a panel holding part (not shown) that is fixed to the truss 1. The panel holding part is covered by a deck device 62.

[0018] The deck device 62 covers the space around the lower part of the parapet panel 61. The deck device 62 has a skirt guard 63, an inner deck 64, and an outer deck 65. The skirt guard 63, the inner deck 64, and the outer deck 65 are each arranged along the longitudinal direction of the truss 1.

[0019] The skirt guard 63 is disposed at a position close to the step 4 when viewed from the parapet panel 61. The skirt guard 63 is disposed away from the parapet panel 61 in the width direction of the truss 1. The skirt guard 63 is attached to the truss 1 via mounting brackets (not shown).

[0020] When the step 4 is located in the outward path section, the upper part of the side of the step 4 faces the lower part of the skirt guard 63. When the step 4 is located in the outward path section, the side of the step 4 is open to the space present below the skirt guard 63.

[0021] The inner deck 64 is disposed between the upper end of the skirt guard 63 and the side of the parapet panel 61. The inner deck 64 covers the space that exists between the lower part of the parapet panel 61 and the skirt guard 63.

[0022] The outer deck 65 is disposed on the opposite side of the steps 4 from the parapet panel 61. The outer deck 65 is attached to the truss 1 by mounting brackets (not shown) that are fixed to the truss 1. The outer deck 65 covers the space that exists around the lower part of the parapet panel 61, on the opposite side of the steps 4 from the parapet panel 61.

[0023] The outer deck 65 has a vertical plate 651 and an upper plate 652. The vertical plate 651 is disposed away from the balustrade panel 61 at a position farther from the steps 4 than the balustrade panel 61 in the width direction of the truss 1. The upper plate 652 is disposed between the upper end of the vertical plate 651 and the side surface of the balustrade panel 61. The upper plate 652 covers the space that exists between the lower part of the balustrade panel 61 and the vertical plate 651. An opening 653 is provided in the upper plate 652 along the longitudinal direction of the truss 1.

[0024] The escalator is provided with a display device 8. The display device 8 has a step mounting portion 80, a reflecting mirror 85, a screen 86, a power supply portion 87 (described later), and a transparent cover 88.

[0025] The step mounting unit 80 is provided on at least one of the multiple steps 4. In this embodiment, a step mounting unit 80 is provided on each of the multiple steps 4. The step mounting unit 80 has a video display 81, a mounting base 82, a power receiving unit 83, and a weight sensor 84.

[0026] 3 is a perspective view showing the step 4 provided with the step mounting portion 80 of FIG. 2. The step 4 is arranged so that the width direction of the step 4 coincides with the width direction of the truss 1. The step 4 has a frame 41, a tread 42, a riser 43, a pair of drive rollers (not shown), and a pair of follower rollers 44. The tread 42, the riser 43, the drive rollers, and the follower rollers 44 are attached to the frame 41.

[0027] The step 42 has a tread surface on which passengers stand. Each step 4 moves along the forward path with the tread surface of the step 42 facing upward and the step 42 held horizontally. When each step 4 moves along the forward path, the side of the step 42 faces the lower part of the skirt guard 63.

[0028] The riser 43 is disposed at the lower end of the tread 42. When each step 4 moves along the forward path, two adjacent steps 4 are displaced vertically from each other, and the riser 43 closes the space created between the treads 42 of each step 4.

[0029] The pair of drive rollers are attached to the upper step end of the frame 41 via a step shaft (not shown). The pair of drive rollers are arranged on both sides of the frame 41 in the width direction of the step 4. The pair of follower rollers 44 are attached to the lower step end of the frame 41. The pair of follower rollers 44 are arranged on both sides of the frame 41 in the width direction of the step 4. The step chain 5 is connected to the step shaft. The step 4 moves along the step path while being pulled by the step chain 5.

[0030] A plurality of step rails (not shown) that guide the movement of each step 4 are fixed to the truss 1. The plurality of step rails individually correspond to each drive roller and each follower roller 44. Each drive roller and each follower roller is placed on the corresponding step rail. The movement of each step 4 is guided by each drive roller and each follower roller rolling on each step rail. Each step 4 is supported by the truss 1 via a plurality of step rails.

[0031] The image display 81 is attached to the back surface of the step 42 via a mounting base 82. As a result, the image display 81 is disposed in the space inside the frame 41. When the step 4 is positioned in the forward path section, the image display 81 is disposed below the step 42. The image display 81 projects light for imaging toward the outside of the step 4 in the width direction.

[0032] The mounting base 82 is attached to the step 42 of the step 4 while supporting the video display 81. In this embodiment, a metal fitting formed by bending a metal plate is used as the mounting base 82.

[0033] The weight sensor 84 is attached to the back surface of the step board 42. The weight sensor 84 detects the magnitude of the weight applied to the step board 42 as weight information. The weight sensor 84 is capable of communicating with the video display 81 via wired or wireless communication. This allows the weight information, which is the detection result of the weight sensor 84, to be transmitted from the weight sensor 84 to the video display 81.

[0034] The power receiving unit 83 has a contact plate and a power storage device. The contact plate is made of a conductive material. A battery, a capacitor, or the like is used as the power storage device. The power receiving unit 83 is attached to the step 4 with the contact plate exposed on the side of the step 4. In this embodiment, the power receiving unit 83 is attached to the frame 41. The power receiving unit 83 is electrically connected to the video display 81 via wiring.

[0035] Figure 4 is a cross-sectional view showing the state when the power receiving unit 83 in Figure 2 receives a supply of power. A power supply unit 87 is provided on the truss 1. The power supply unit 87 is located below the skirt guard 63. The power supply unit 87 is located at a position where it comes into contact with the contact plate of the power receiving unit 83 when the step 4 moves along the outbound section. In this embodiment, the position of the power supply unit 87 relative to the truss 1 is adjustable in the width direction of the truss 1.

[0036] As the steps 4 move relative to the truss 1, the power receiving unit 83 passes through a position where it comes into contact with the power supply unit 87. By coming into contact with the power receiving unit 83, the power supply unit 87 supplies power to the power receiving unit 83 to be supplied to the video display 81. The power storage device of the power receiving unit 83 stores the power supplied from the power supply unit 87 to the power receiving unit 83. The video display 81 operates by using the power stored in the power storage device of the power receiving unit 83. The power stored in the power storage device of the power receiving unit 83 is also supplied to the weight sensor 84.

[0037] The power supply unit 87 has a roller shaft 871 and a power supply roller 872. The roller shaft 871 is fixed to the truss 1. The roller shaft 871 is disposed so that the axis of the roller shaft 871 is perpendicular to both the movement direction of the steps 4 and the width direction of the truss 1.

[0038] The power supply roller 872 is provided on the roller shaft 871. The power supply roller 872 is rotatable relative to the truss 1 around the axis of the roller shaft 871. The power supply roller 872 is made of a conductive material. When the step 4 moves along the outbound path and reaches a position where the power receiving part 83 comes into contact with the power supply part 87, the power receiving part 83 comes into contact with the outer periphery of the power supply roller 872. When the power receiving part 83 comes into contact with the outer periphery of the power supply roller 872, power is supplied from the power supply roller 872 to the power receiving part 83.

[0039] 5 is a top view showing a state when power receiving unit 83 in FIG. 4 starts to come into contact with power feeding unit 87. FIG. 6 is a top view showing a state when power receiving unit 83 in FIG. 5 is in the middle of coming into contact with power feeding unit 87. FIG. 7 is a top view showing a state when power receiving unit 83 in FIG. 6 has finished coming into contact with power feeding unit 87. When power receiving unit 83 passes a position where it comes into contact with power feeding roller 872, the position of power receiving unit 83 relative to power feeding unit 87 changes in the order of the positions shown in FIG. 5, FIG. 6, and FIG. 7. When power receiving unit 83 passes a position where it comes into contact with power feeding roller 872, it rotates power feeding roller 872 relative to truss 1 while in contact with power feeding roller 872.

[0040] As shown in Fig. 2, the reflecting mirror 85 is provided on the outer deck 65. As a result, the reflecting mirror 85 is disposed on the opposite side of the steps 4 when viewed from the balustrade panel 61. The reflecting mirror 85 is disposed on the inside of the outer deck 65, facing the side closer to the steps 4. In this embodiment, the reflecting mirror 85 is fixed to a vertical plate 651 of the outer deck 65. Also, in this embodiment, the reflecting mirror 85 is disposed along the direction in which the steps 4 move on the outbound path.

[0041] The light for the image projected from the image display 81 passes through the space below the balustrade panel 61 and reaches the reflector 85. The reflector 85 reflects the light for the image projected from the image display 81.

[0042] The transparent cover 88 is attached to the upper plate 652 of the outer deck 65. The transparent cover 88 covers the opening 653. The transparent cover 88 is a transparent flat plate that allows light to pass through.

[0043] The screen 86 is provided on the balustrade panel 61. The screen 86 is attached to a portion of the balustrade panel 61 that is located above the outer deck 65. The screen 86 is also attached to one of both side surfaces of the balustrade panel 61 that faces the outer deck 65. In this embodiment, a transparent screen film is used as the screen 86. In this embodiment, the screen 86 is attached to the balustrade panel 61 along the direction in which the steps 4 move on the outbound section.

[0044] The imaging light reflected by reflecting mirror 85 passes through opening 653 and reaches screen 86. When the imaging light passes through opening 653, it is transmitted through transparent cover 88. Screen 86 projects an image corresponding to the imaging light reflected by reflecting mirror 85.

[0045] Fig. 8 is a block diagram showing the configuration of the video display 81 of Fig. 2. The video display 81 has a projection unit 811, an interface unit 812, a communication unit 813, and a processing unit 814.

[0046] The projection unit 811 has a function of projecting light for an image. The operation of the projection unit 811 is controlled by the processing unit 814 via the interface unit 812.

[0047] The interface unit 812 relays communication between the weight sensor 84 and the processing unit 814. Weight information, which is the detection result of the weight sensor 84, is sent to the processing unit 814 via the interface unit 812.

[0048] The communication unit 813 communicates with the conveyor control device 11 that controls the operation of the escalator via wired or wireless communication. As a wireless communication technology between the conveyor control device 11 and the communication unit 813, a technology such as a wireless LAN (Local Area Network) or Bluetooth (registered trademark) is used.

[0049] The conveyor control device 11 is capable of outputting information that can be provided to passengers as passenger-provided information to the communication unit 813. Examples of passenger-provided information include operation information regarding escalator operation, advertising information regarding advertisements, and store information regarding stores within the building. Examples of operation information include directional display information that shows either upward operation or downward operation as an arrow image. The passenger-provided information output from the conveyor control device 11 is sent to the processing unit 814 via the communication unit 813. The conveyor control device 11 supplies power to the power supply unit 87.

[0050] The processing unit 814 includes a CPU (Central Processing Unit) 815 and a storage unit 816 .

[0051] The memory unit 816 stores passenger-provided information from the conveyor control device 11 and weight information from the weight sensor 84. The memory unit 816 also stores in advance a determination threshold for comparison with the weight information.

[0052] The CPU 815 performs a boarding determination, which is a determination as to whether or not a passenger has stood on the step 4, based on the weight information from the weight sensor 84. The boarding determination by the CPU 815 is performed by comparing the weight information with a boarding determination threshold pre-stored in the storage unit 816. The CPU 815 determines that a passenger is standing on the step 4 when the weight information is equal to or greater than the boarding determination threshold, and determines that a passenger is not standing on the step 4 when the weight information is less than the boarding determination threshold.

[0053] When the CPU 815 determines that a passenger is standing on the steps 4, it controls the projection unit 811 to execute projection of light for imaging. On the other hand, when the CPU 815 determines that a passenger is not standing on the steps 4, it controls the projection unit 811 to stop projection of light for imaging. In other words, the image display device 81 controls execution and stop of projection of light for imaging based on weight information that is the detection result of the weight sensor 84.

[0054] The CPU 815 projects light for imaging in accordance with the passenger-provided information stored in the memory unit 816 from the conveyor control device 11. As a result, an image including the passenger-provided information is projected on the screen 86 by the light for imaging.

[0055] Next, the operation of the display device 8 will be described. When each step 4 moves due to the driving force of the driving machine, the step mounting portion 80 provided on each step 4 moves together with the step 4. When no passenger is standing on the step 4, the projection of image light from the image display 81 is stopped.

[0056] When a passenger steps on the step 4, the CPU 815 of the video display 81 determines that the passenger is on the step 4 based on the weight information detected by the weight sensor 84. Furthermore, the memory unit 816 of the video display 81 stores the passenger-provided information received from the conveyor control device 11. As a result, the video display 81 starts projecting light for an image according to the passenger-provided information.

[0057] When the image light is projected from the image display device 81, the image light is reflected by the reflecting mirror 85, as shown in FIG. 2, and then passes through the opening 653 to reach the screen 86. When the image light passes through the opening 653, it is transmitted through the transparent cover 88. When the image light reaches the screen 86, an image corresponding to the image light is projected onto the screen 86. As a result, the passenger-provided information included in the image is displayed on the balustrade panel 61.

[0058] The image displayed on the screen 86 moves together with the steps 4 on which the passengers stand. This allows the passengers on the steps 4 to more reliably recognize the passenger-provided information included in the image displayed on the screen 86.

[0059] When the passenger steps down from the step 4, the CPU 815 of the video display 81 determines that the passenger is not standing on the step 4 based on the weight information of the weight sensor 84. As a result, the video display 81 stops projecting the light for the video.

[0060] Furthermore, when the steps 4 are moving, if the power receiving unit 83 passes a position where it comes into contact with the power supply unit 87, the power receiving unit 83 comes into contact with the power supply unit 87, and power is supplied from the power supply unit 87 to the power receiving unit 83. This ensures that the video display 81 continues to operate.

[0061] In this display device 8, a step-mounted unit 80 having a video display 81 is provided on the step 4. A reflector 85 that reflects the video light projected from the video display 81 is provided on the outer deck 65, which is located on the opposite side of the step 4 from the balustrade panel 61. The balustrade panel 61 is provided with a screen 86 that displays an image corresponding to the video light reflected by the reflector 85. This prevents the video light from passing through the space above the step 4 that is closer to the step 4 than the balustrade panel 61. This prevents the video light from being blocked by passengers on the step 4, preventing at least a portion of the image from being lost due to the passenger's shadow. This allows the image to be more reliably projected onto the screen 86. Furthermore, the projection distance of the video light can be longer than when the video light is projected from the inner deck 64 toward the balustrade panel 61. This allows the size of the image projected on the screen 86 to be larger, making it easier for passengers on the step 4 to see the image. Therefore, it is no longer necessary to forcibly enlarge the size of the image projected on the screen 86 using a wide-angle lens, and distortion of the image projected on the screen 86 can be more reliably suppressed.

[0062] Additionally, a power supply unit 87 is provided on the truss 1. A power receiving unit 83, which is electrically connected to the video display 81, passes through a position where it comes into contact with the power supply unit 87 as the steps 4 move relative to the truss 1. By coming into contact with the power receiving unit 83, the power supply unit 87 supplies the power to the power receiving unit 83 for supply to the video display 81. This makes it possible to more reliably supply power to the video display 81, and to prevent the video display 81 from becoming inoperable due to a lack of power.

[0063] Furthermore, power supply unit 87 has a power supply roller 872 that is rotatable relative to truss 1. When power receiving unit 83 passes a position where it comes into contact with power supply roller 872, it rotates power supply roller 872 relative to truss 1 while in contact with power supply roller 872. This prevents power receiving unit 83 from rubbing against power supply roller 872 as it moves. This reduces wear on power receiving unit 83 and power supply roller 872, thereby extending the lifespan of power receiving unit 83 and power supply unit 87.

[0064] The step mounting unit 80 also has a weight sensor 84 that detects the magnitude of the weight applied to the step 4 as weight information. The video display 81 controls the start and stop of the projection of the video light based on the weight information detected by the weight sensor 84. This makes it possible to project videos onto the screen 86 corresponding only to steps 4 on which passengers are standing. This makes it possible to avoid unnecessary video projection onto the screen 86 when no passengers are present.

[0065] Embodiment 2 9 is an enlarged view showing the main part of the display device according to Embodiment 2. The mount 82 has a mount main body 821 and an adjustment section 822.

[0066] The mounting base main body 821 has a fixed plate portion 821a and a receiving plate portion 821b. The fixed plate portion 821a is fixed to the back surface of the step 42 inside the frame 41. When the step 4 is located in the forward path portion, the fixed plate portion 821a protrudes downward from the back surface of the step 42.

[0067] The receiving plate portion 821b is attached to the end of the fixed plate portion 821a via an adjustment portion 822. When the step 4 is located in the outward path portion, the receiving plate portion 821b is attached to the lower end of the fixed plate portion 821a.

[0068] The image display 81 is fixed to the receiving plate portion 821b with the optical axis of the image display 81 facing outward in the width direction of the step 4. The image display 81 projects light for imaging in a direction along the optical axis of the image display 81.

[0069] The adjustment unit 822 has a rotation shaft and an adjustment motor. The rotation shaft of the adjustment unit 822 is arranged along the depth direction of the step 4. The depth direction of the step 4 is a direction perpendicular to the width direction of the step 4 and is a direction along the tread surface of the tread board 42. The adjustment motor of the adjustment unit 822 is connected to the rotation shaft of the adjustment unit 822. Power can be supplied to the adjustment motor of the adjustment unit 822 from the video display 81.

[0070] The receiving plate portion 821b is rotatable relative to the fixed plate portion 821a around the rotation axis of the adjustment portion 822 by the driving force of the adjustment motor of the adjustment portion 822. This allows the adjustment portion 822 to adjust the angle of the receiving plate portion 821b relative to the fixed plate portion 821a. The adjustment portion 822 adjusts the direction of the light for the image projected from the image display device 81 relative to the steps 4 by adjusting the angle of the receiving plate portion 821b relative to the fixed plate portion 821a.

[0071] 10 is an enlarged view showing a state in which the angle of receiving plate portion 821b relative to fixed plate portion 821a in Fig. 9 has been adjusted. The position at which the light for imaging projected from image display 81 reaches reflecting mirror 85 changes by adjusting the direction of the light for imaging projected from image display 81 relative to step 4. When step 4 is located in the outbound path portion, the greater the angle of receiving plate portion 821b relative to fixed plate portion 821a, the further downward the position at which the light for imaging projected from image display 81 reaches reflecting mirror 85.

[0072] 11 is a block diagram showing the configuration of video display 81 in display device 8 according to embodiment 2. Video display 81 has a projection unit 811, an interface unit 812, a communication unit 813, a processing unit 814, and a reflecting mirror detection unit 817.

[0073] The reflecting mirror detection unit 817 detects the position of the reflecting mirror 85 within a set range as seen from the reflecting mirror detection unit 817. An example of the reflecting mirror detection unit 817 is an image processing device that detects the position of the reflecting mirror 85 within a set range of an image acquired by photographing the reflecting mirror 85. Position detection information, which is the detection result of the reflecting mirror detection unit 817, is sent to the processing unit 814 via the interface unit 812.

[0074] The memory unit 816 of the processing unit 814 stores position detection information from the reflecting mirror detection unit 817. The memory unit 816 also stores position reference information for comparison with the position detection information in advance. The position reference information is information that indicates the reference position of the reflecting mirror 85 within the set range.

[0075] The CPU 815 controls the adjustment unit 822 based on the position detection information from the reflecting mirror detection unit 817 and the position reference information stored in advance in the storage unit 816. That is, the CPU 815 controls the adjustment unit 822 so that the position of the reflecting mirror 85 in the set range based on the position detection information coincides with the reference position of the reflecting mirror 85 in the set range based on the position reference information. In this embodiment, the adjustment unit 822 is controlled so that the position of the reflecting mirror 85 in the set range based on the position detection information coincides in the up-down direction with the reference position of the reflecting mirror 85 in the set range based on the position reference information. A control signal from the CPU 815 to the adjustment unit 822 is sent to the adjustment unit 822 via the interface unit 812.

[0076] That is, based on the detection result of the reflecting mirror detector 817, the processing unit 814 controls the adjustment unit 822 so that the position of the reflecting mirror 85 coincides with the reference position within the set range. As a result, the direction of the light for the image projected from the image display 81 coincides with the direction toward the reference position of the reflecting mirror 85. Therefore, for example, if vibration occurs in the step 4 as the step 4 moves along the outbound path, the control of the adjustment unit 822 by the processing unit 814 makes it less likely that the image projected on the screen 86 will be blurred. Examples of cases in which vibration occurs in the step 4 include when the follower roller 44 passes over a joint in the step rail, or when the step 4 is impacted by a passenger standing on the step 4. The other configurations are the same as those in the first embodiment.

[0077] In this type of display device 8, the adjustment unit 822 of the mounting base 82 can adjust the direction of the light for imaging projected from the image display 81 with respect to the steps 4. The reflecting mirror detection unit 817 detects the position of the reflecting mirror 85 within a set range as seen from the reflecting mirror detection unit 817. Based on the detection result of the reflecting mirror detection unit 817, the processing unit 814 controls the adjustment unit 822 so that the position of the reflecting mirror 85 coincides with a reference position within the set range. Therefore, even if the steps 4 vibrate, the position at which the light for imaging projected from the image display 81 reaches the reflecting mirror 85 can be made less likely to change in the vertical direction relative to the reflecting mirror 85. This makes it possible to make it less likely that the image projected on the screen 86 will shake even if the steps 4 vibrate.

[0078] In the second embodiment, the mounting base 82 has one adjustment unit 822. However, the mounting base 82 may have two or more adjustment units 822. For example, if the mounting base 82 has two adjustment units, a first adjustment unit and a second adjustment unit, the rotation axis of the first adjustment unit is arranged along the depth direction of the step 4, and the rotation axis of the second adjustment unit is arranged along the width direction of the step 4. In this case, the receiving plate 821b has two separate plates, a first plate and a second plate. The video display 81 is fixed to the first plate. The first plate is attached to the second plate via the second adjustment unit. The second plate is attached to the fixing plate 821a via the first adjustment unit. In this way, the direction of the video light relative to the step 4 can be adjusted not only around the rotation axis of the first adjustment unit but also around the rotation axis of the second adjustment unit. This not only makes it possible to adjust the position of the image projected on the screen 86 in the vertical direction, but also makes it possible to adjust the angle of the image projected on the screen 86 by tilting it in accordance with the direction of movement of the steps 4.

[0079] Embodiment 3 12 is a side view showing a portion of an escalator located on an upper floor, in which a display device according to embodiment 3 is provided. A plurality of reflecting mirrors 85 are provided on a vertical plate 651 of an outer deck 65 at intervals in the direction of movement of the steps 4.

[0080] In this embodiment, a reflecting mirror 85 for an upper floor, a reflecting mirror 85 for a lower floor, and an intermediate reflecting mirror 85 are provided on the outer deck 65 at intervals in the direction of movement of the steps 4 in the outbound section. The reflecting mirror 85 for the upper floor is provided in a portion of the outer deck 65 located on the upper floor. The reflecting mirror 85 for the lower floor is provided in a portion of the outer deck 65 located on the lower floor. The intermediate reflecting mirror 85 is provided in a portion of the outer deck 65 located between the reflecting mirror 85 for the upper floor and the reflecting mirror 85 for the lower floor. The intermediate reflecting mirror 85 is arranged along the direction of movement of the steps 4 in the outbound section.

[0081] The screen 86 is attached to the parapet panel 61 continuously along the direction of movement of the steps 4 in the forward section from the lower floor to the upper floor.

[0082] In this embodiment, an ascending operation is performed in which the step 4 moves from the lower floor to the upper floor. When the step 4 moves on the outgoing path from the lower floor to the upper floor, the step 4 moves sequentially through each reflector arrangement range in which a reflector 85 for the lower floor, a middle reflector 85, and a reflector 85 for the upper floor are respectively arranged. Between each reflector arrangement range, a reflector removal range is formed in which the reflector 85 has been removed.

[0083] The light for the image projected from the image display 81 reaches the screen 86 only when the step 4 moves through each reflector placement range. On the other hand, when the step 4 moves through each reflector removal range, the light for the image projected from the image display 81 does not reach the screen 86. As a result, when the step 4 moves along the outbound path, the step 4 passes alternately through the reflector placement range and the reflector removal range, causing the image projected on the screen 86 to flash as the step 4 moves.

[0084] In this embodiment, an image of an arrow indicating the direction of travel of the steps 4 from the lower floor to the upper floor is displayed on the screen 86 as information to be provided to passengers. The image displayed on the screen 86 disappears once the steps 4 move out of the reflector arrangement range in which the intermediate reflector 85 is arranged, and is displayed again on the screen 86 when the steps 4 enter the reflector arrangement range in which the upper floor reflector 85 is arranged. This causes the image of the arrow displayed on the screen 86 to be emphasized when passengers disembark.

[0085] Furthermore, the image displayed on the screen 86 disappears once the step 4 moves out of the reflector arrangement range where the upper floor reflector 85 is located, and is displayed again on the screen 86 when the step 4 enters the reflector arrangement range where the intermediate reflector 85 is located. This causes the image of the arrow displayed on the screen 86 to be emphasized when passengers board. The other configurations are the same as those in the first embodiment.

[0086] In such a display device 8, a plurality of reflecting mirrors 85 are provided on the outer deck 65 at intervals in the direction of movement of the steps 4. This allows the image displayed on the screen 86 to flash in accordance with the movement of the steps 4. This makes it possible to emphasize the passenger-provided information included in the image displayed on the screen 86, and more reliably provide the passenger-provided information to passengers.

[0087] In the above-described third embodiment, the configuration in which a plurality of reflecting mirrors 85 are provided on the outer deck 65 at intervals in the moving direction of the steps 4 is applied to the escalator according to the first embodiment. However, a configuration in which a plurality of reflecting mirrors 85 are provided on the outer deck 65 at intervals in the moving direction of the steps 4 may also be applied to the escalator according to the second embodiment.

[0088] Furthermore, in the above-described third embodiment, the number of reflectors 85 provided on the outer deck 65 is three: a reflector 85 for an upper floor, a reflector 85 for a lower floor, and a reflector 85 for an intermediate floor. However, the number of reflectors 85 provided on the outer deck 65 may be two, or four or more. In this case, the two or four or more reflectors 85 are provided on the outer deck 65 at intervals in the direction of movement of the steps 4. In this way, too, the image displayed on the screen 86 can be made to flash as the steps 4 move.

[0089] Furthermore, in the above-described third embodiment, the screens 86 are attached to the balustrade panels 61 continuously from the lower floor to the upper floor. However, this is not limited to this. For example, a plurality of screens 86 may be attached to the balustrade panels 61 at intervals corresponding to the positions of the reflectors 85 in the direction of movement of the steps 4 in the outbound section. In this way, too, the images projected on the screens 86 can be made to flash as the steps 4 move.

[0090] In addition, in each of the above-described embodiments, the opening 653 formed in the upper plate 652 of the outer deck 65 is covered by the transparent cover 88. However, if there is no problem in leaving the opening 653 open, the transparent cover 88 may be omitted.

[0091] In each of the above embodiments, the passenger-provided information output from the conveyor control device 11 is sent to the processing unit 814 via a communication unit 813 that is different from the power supply unit 87 and the power receiving unit 83. However, the passenger-provided information output from the conveyor control device 11 may be sent to the processing unit 814 via the power supply unit 87 and the power receiving unit 83 using power line communication (PLC) technology.

[0092] In each of the above-described embodiments, power supply unit 87 has power supply roller 872 that is rotatable relative to truss 1. However, power supply unit 87 may be in any form as long as it is in contact with power receiving unit 83 and can supply power to power receiving unit 83. For example, a conductive block made of a conductive material may be fixed to truss 1 as power supply unit 87.

[0093] Furthermore, in each of the above-described embodiments, a weight sensor 84 is provided on the step 4. However, the weight sensor 84 is not necessary. Even without the weight sensor 84, the image can be projected onto the screen 86 by continuing to project the image light from the image display 81 regardless of whether there is a passenger or not. This makes it possible to avoid a situation where the image is not displayed on the screen 86 when a passenger stands on the step 4.

[0094] Furthermore, in each of the above-described embodiments, the step mounting unit 80 is mounted on each of the plurality of steps 4. However, the step mounting unit 80 may be mounted on only some of the plurality of steps 4. This also allows the image to be projected onto the screen 86 more reliably.

[0095] In addition, in each of the above-described embodiments, the display device 8 is applied to an escalator. However, the display device 8 may also be applied to a moving walkway serving as a passenger conveyor.
