The substrate on which the light-emitting element 20 is mounted is arranged, for example, in the fitting part 19.

[0029] The newly installed display board 21 is a part whose front face faces the boarding area 2. The newly installed display board 21 is formed of a material that transmits visible light. The rear face of the newly installed display board 21 faces the light-emitting element 20. The rear face of the newly installed display board 21 is attached to, for example, the fitting part 19. The front face of the newly installed display board 21 may be inclined downward so as to be easily visible to the users of the boarding area 2. Further, when characters such as the floor corresponding to the front face of the newly installed display board 21 are shown, the characters may be attached by pasting a label or the like, or may be shown by the unevenness on the front face of the newly installed display board 21.

[0030] FIG. 4 is a diagram showing the configuration of the display device 4 to which the display board unit 16 according to Embodiment 1 is attached. In FIG. 4, a cross-section taken along the plane A of FIG. 1 is shown.

[0031] The newly installed display board 21 is attached to the edge of the display hole 9 corresponding to the same display as the display corresponding to the display board unit 16 from the front of the decorative board 5. The size of the front surface of the newly installed display board 21 is larger than the size of the display hole 9. Therefore, the front surface of the newly installed display board 21 conceals the display hole 9 from the boarding area 2. Also, the newly installed display board 21 conceals the light-emitting element 20 from the boarding area 2.

[0032] In the display board unit 16 attached to the display device 4, the light-emitting element 20 receives a lighting signal for the display corresponding to the display board unit 16 through the first connector 17. The light-emitting element 20 emits visible light when it receives the lighting signal. The light emission of the light-emitting element 20 can be visually recognized by the users in the boarding area 2 through the newly installed display board 21. Therefore, the lighting of the display corresponding to the display board unit 16 is shown to the users by the light emission of the light-emitting element 20 of the display board unit 16 corresponding to each display.

[0033] Subsequently, an example of a method for modifying the display device 4 will be described with reference to FIG. 5. FIG. 5 is a diagram showing an example of a modification method according to Embodiment 1. In FIG. 5, a cross-section taken along the plane A of FIG. 1 is shown.

[0034] The method for modifying the display device 4 includes a pulling-out step, a connecting step, and an attaching step. The worker who performs the modification work of the display device 4 performs the operations of the pulling-out step, the connecting step, and the attaching step in this order.

[0035] In the pulling-out step, the worker removes each existing display board 6 and each existing lamp 7 from the display device 4. Each existing display board 6 is removed from the rear of the decorative board 5. Each existing lamp 7 is removed from the socket 11.

[0036] After that, the worker draws out the wiring that transmits the lighting signal of the display corresponding to the removed existing display board 6 and existing lamp 7 to the display hole 9 corresponding to the display. At this time, the worker draws out the wiring using, for example, the connector unit 22. The connector unit 22 is a device including a base 23, a second electric wire 24, and a second connector 25. The base 23 is the part connected to the socket 11. The base 23 receives the lighting signal of the corresponding display through the connected socket 11. The second electric wire 24 is the part that transmits the electrical signal between the base 23 and the second connector 25. The second connector 25 is the terminal that outputs the lighting signal input through the base 23. The worker attaches the base 23 of the connector unit 22 to the socket 11 from which the existing lamp 7 has been removed. The worker draws out the second connector 25 to the display hole 9 corresponding to the existing lamp 7. In this way, the wiring that transmits the lighting signal of the display corresponding to the existing lamp 7 is drawn out to the display hole 9 corresponding to the display. Note that the second connector 25 only needs to be drawn out to a range where the hand of the worker in the landing 2 can reach from the display hole 9. Alternatively, the second connector 25 may be drawn out to the outside of the display device 4 through the display hole 9 from the side of the landing 2 with respect to the decorative panel 5.

[0037] The work of the drawing-out process is performed, for example, through the inspection opening 13. At this time, the lamp case 8 may remain attached. The removed existing display board 6 and existing lamp 7 are removed to the outside of the display device 4 through the inspection opening 13, for example. When the inspection opening 13 is not provided in the display device 4, etc., the work of the drawing-out process may be performed, for example, from above the cage in the hoistway.

[0038] In the connection process, the worker electrically connects the light-emitting element 20 of the display board unit 16 corresponding to the display for which the work of the drawing-out process has been performed to the wiring drawn out to the display hole 9 corresponding to the display. In this example, the worker electrically connects the light-emitting element 20 to the drawn-out wiring by connecting the first connector 17 and the second connector 25.

[0039] In the installation process, the operator attaches the new display board 21 of the display board unit 16 corresponding to the display for which the work of the connection process has been performed, from the front of the decorative panel 5 to the edge of the display hole 9 corresponding to the display. The new display board 21 is attached, for example, by adhesion. In this example, the new display board 21 is attached to the decorative panel 5 by adhesion using a double-sided tape 26. The double-sided tape 26 is, for example, a foam base double-sided tape or the like. In the installation process, the operator attaches the double-sided tape 26 to the rear edge of the new display board 21 of the display board unit 16. Then, the operator inserts the fitting portion 19 of the display board unit 16 into the corresponding display hole 9 from the front. Then, the operator presses the rear surface of the new display board 21 against the edge of the display hole 9 from the front. Thereby, the display board unit 16 is attached to the decorative panel 5. Note that the new display board 21 may be attached to the decorative panel 5 by adhesion using an adhesive applied to the rear edge of the new display board 21. In the modification of the display device 4 of this example, the decorative panel 5 is continuously used.

[0040] In this way, the modification of the display device 4 is performed by replacing the existing lamp 7 and the existing display board 6 with a new display board unit 16 for each display. Note that the operator may continuously perform the connection process and the installation process for each display.

[0041] Note that in the pulling-out process, the operator may remove the socket 11 itself. At this time, the operator pulls out the wiring itself connected to the socket 11 up to the display hole 9. In this case, the operator may not use the connector unit 22. Alternatively, when the length of the wiring connected to the socket 11 is not sufficient, the operator may perform the pulling-out up to the display hole 9 by connecting another electric wire to the wiring connected to the socket 11 and extending it or the like.

[0042] As described above, the display panel unit 16 according to Embodiment 1 corresponds to any one of a plurality of displays of the elevator 1 in the display device 4. The display device 4 includes a decorative panel 5. A plurality of display holes 9 are provided on the front surface of the decorative panel 5. Each display hole 9 corresponds to any one of the displays. The display panel unit 16 includes a first connector 17, a light-emitting element 20, and a newly installed display panel 21. The first connector 17 receives a signal corresponding to the display. The light-emitting element 20 emits visible light based on the signal received by the first connector 17. The rear surface of the newly installed display panel 21 faces the light-emitting element 20. The newly installed display panel 21 transmits the visible light emitted by the light-emitting element 20. The front surface of the newly installed display panel 21 is larger than the display hole 9 corresponding to the display. The newly installed display panel 21 is attached to the edge of the display hole 9 from the front of the decorative panel 5. Also, the modification method according to Embodiment 1 includes a pulling-out step, a connecting step, and an attaching step. The pulling-out step is a step of removing the existing lamp 7 and the existing display panel 6 corresponding to each display and pulling out the wiring for transmitting the signal of the display to the display hole 9 corresponding to the display. Here, the existing lamp 7 is a device that emitted visible light based on the signal of the display. The existing display panel 6 is a device that transmitted the visible light emitted by the existing lamp 7. The connecting step is a step of connecting the newly installed light-emitting element 20 to the wiring pulled out to the display hole 9 corresponding to the display for the display on which the operation of the pulling-out step has been performed. Here, the newly installed light-emitting element 20 is an element that emits visible light based on the signal of the display. The attaching step is a step of attaching the newly installed display panel 21 to the edge of the display hole 9 corresponding to the display from the front of the decorative panel 5 for the display on which the operation of the connecting step has been performed. Here, the newly installed display panel 21 is a device corresponding to the display and is a device that transmits the visible light emitted by the newly installed light-emitting element 20 provided on the rear surface.

[0043] With such a configuration, it becomes possible to modify the display device 4 without the need for processing such as making holes in the decorative panel 5 of the existing display device 4. Therefore, the workload of the modification work of the display device 4 is reduced. In addition, the operator can connect and attach the display panel unit 16 from the front of the decorative panel 5 at the landing 2. Therefore, the workability of the modification work of the display device 4 is improved.

[0044] Further, the newly installed display panel 21 is attached by adhesion to the edge of the display hole 9 of the corresponding display on the front surface of the decorative panel 5.

[0045] With such a configuration, the operator can attach the display panel unit 16 by pressing the newly installed display panel 21 from the front. Therefore, the workability of the modification work of the display device 4 is improved. In addition, the configuration of the display panel unit 16 becomes simple.

[0046] Further, the display panel unit 16 includes a fitting portion 19. The fitting portion 19 is provided on the rear surface of the newly installed display panel 21. The fitting portion 19 is fitted into the display hole 9 of the corresponding display.

[0047] With such a configuration, the position and orientation of the display panel unit 16 are less likely to deviate from the position and orientation of the display hole 9. Therefore, the workability of the modification work of the display device 4 is improved. In addition, the design property of the modified display device 4 is less likely to deteriorate. Note that the fitting portion 19 may be a part of the newly installed display panel 21. That is, the newly installed display panel 21 may have an integrally formed fitting portion 19 on the rear surface.

[0048] Embodiment 2. In Embodiment 2, the points different from the example disclosed in Embodiment 1 will be described in particular detail. For the features not described in Embodiment 2, any of the features of the example disclosed in Embodiment 1 may be adopted.

[0049] FIG. 6 is a side view of the display panel unit 16 according to Embodiment 2.

[0050] The display board unit 16 includes a fastener 27. The fastener 27 is provided behind the front surface of the display board. The fastener 27 may be provided behind the rear surface of the display board. In this example, the fastener 27 is provided in the fitting portion 19. The fastener 27 protrudes from the outer surface of the fitting portion 19. The fastener 27 is attached so as to be able to enter inside from the outer surface of the fitting portion 19 by elastic deformation.

[0051] Subsequently, an example of a method for repairing the display device 4 will be described with reference to FIG. 7. FIG. 7 is a diagram showing an example of a repair method according to the second embodiment. In FIG. 7, a cross section taken along the plane A of FIG. 1 is shown.

[0052] In the attachment step, the operator fits the fitting portion 19 of the display board unit 16 into the display hole 9 corresponding to the display board unit 16 from the front. At this time, the fastener 27 of the display board unit 16 hits the edge of the display hole 9 and enters inside from the outer surface of the fitting portion 19 by elastic deformation. As a result, the fastener 27 passes through the display hole 9 from the front to the rear. The fastener 27 that has passed through the display hole 9 protrudes from the outer surface of the fitting portion 19 due to the restoration of the elastic deformation. At this time, the fastener 27 hangs on the rear surface of the edge of the display hole 9. Thereby, the display board unit 16 is attached to the decorative panel 5.

[0053] As described above, the display board unit 16 according to the second embodiment includes a fastener 27. The fastener 27 is provided behind the front surface of the newly installed display board 21. The fastener 27 can pass through the corresponding display hole 9 of the display from the front to the rear by elastic deformation. When the fastener 27 passes through the display hole 9, the elastic deformation is restored, and the fastener 27 hangs on the rear surface of the edge of the display hole 9 to attach the newly installed display board 21 to the decorative panel 5.

[0054] With such a configuration, the operator can attach the display board unit 16 by pressing the newly installed display board 21 from the front without the need to paste double-sided tape 26 or apply an adhesive. Therefore, the workability of the repair work of the display device 4 is improved.

[0055] Embodiment 3. In Embodiment 3, the points different from the examples disclosed in Embodiment 1 or Embodiment 2 will be described in particular detail. For features not described in Embodiment 3, any features of the examples disclosed in Embodiment 1 or Embodiment 2 may be adopted.

[0056] FIG. 8 is a diagram showing an example of the modification method according to Embodiment 3. In FIG. 8, the display device 4 as viewed from above in the pulling-out process is shown.

[0057] In the pulling-out process, the operator performs work using the holder 28. The holder 28 is a tool for holding the wiring pulled out in the pulling-out process. The holder 28 includes a base portion 29, a pair of attachment portions 30, a plurality of branch portions 31, and a plurality of gripping portions 32.

[0058] The base portion 29 is a portion forming the framework of the holder 28. In this example, the base portion 29 is a member long in the left-right direction. The length of the base portion 29 is longer than the distance from the left edge of the leftmost display hole 9 to the right edge of the rightmost display hole 9, for example, when a plurality of display holes 9 are arranged in the left-right direction.

[0059] The pair of attachment portions 30 are portions for attaching the holder 28 to the decorative panel 5. When the decorative panel 5 is made of a material containing a ferromagnetic substance such as iron, each attachment portion 30 is, for example, a magnet or the like. Alternatively, each attachment portion 30 may be a suction cup or the like. One attachment portion 30 is provided at the left end of the base portion 29. The other attachment portion 30 is provided at the right end of the base portion 29. The left attachment portion 30 is attached to the decorative panel 5 on the left side of the leftmost display hole 9. The right attachment portion 30 is attached to the decorative panel 5 on the right side of the rightmost display hole 9. At this time, the base portion 29 of the attachment portion 30 is arranged so as to extend from the leftmost display hole 9 to the rightmost display hole 9. The pair of attachment portions 30 are attached to, for example, the rear surface of the decorative panel 5.

[0060] Each branch portion 31 corresponds to one of the display holes 9. Each branch portion 31 is a portion that extends from the base portion 29 attached to the decorative panel 5 toward the corresponding display hole 9.

[0061] Each gripping portion 32 corresponds to one of the display holes 9. Each gripping portion 32 is provided at the tip of the branch portion 31 corresponding to the same display hole 9. Each gripping portion 32 is a portion that grips the wiring drawn out to the corresponding display hole 9. Each gripping portion 32 is, for example, a cable clip or the like.

[0062] In the drawing-out process, the operator removes the lamp case 8 from the existing display device 4. Thereafter, the operator attaches the holder 28 to the rear surface of the decorative panel 5 so that the base portion 29 extends from the leftmost display hole 9 to the rightmost display hole 9. Thereafter, the operator draws out the wiring so that the second connector 25 comes out to the outside of the display device 4 through the display hole 9. The operator causes the wiring drawn out to the display hole 9 to be gripped by the gripping portion 32 corresponding to the display hole 9. Thereby, the backward return of the wiring drawn out in the drawing-out process is prevented. For this reason, it becomes easier for the operator to perform the work in the subsequent connection process.

[0063] The holder 28 is removed, for example, after the connection process. Note that the holder 28 may remain attached to the rear surface of the decorative panel 5 even after the repair work when the holder 28 is hidden from the landing 2 and does not interfere with the operation of the elevator 1.

[0064] Note that the holder 28 may be individually attached for each display hole 9. Also, the holder 28 may be attached to the front surface of the decorative panel 5. The operator may remove the holder 28 for the display hole 9 corresponding to each display after the connection process for each display.

[0065] As described above, the drawer-out process of the modification method according to the third embodiment includes a procedure of attaching the fixture 28 to the decorative panel 5 and a procedure of holding the wiring drawn out to the display hole 9 on the fixture 28 attached to the decorative panel 5 in a state where the wiring is drawn out from the display hole 9 to the landing 2 side from the decorative panel 5.

[0066] With such a configuration, the backward return of the wiring drawn out in the drawer-out process is prevented, so that the backward movement of the process in the modification work is prevented. Therefore, the workability of the modification work of the display device 4 is improved.
