Description

[Technical field]

[0001] The present disclosure relates to an operation input device through which operations are input to a device. [Background technology]

[0002] Japanese Patent No. 6841372 describes an elevator operating device for operating an elevator. The elevator operating device is equipped with a destination floor registration switch for determining the destination floor of the elevator car. Below the destination floor registration push button switch are an open push button switch for opening the door, a close push button switch for closing the door, and an emergency call button switch for reporting to the outside in the event of an emergency.

[0003] Elevator push button switches, such as destination floor registration push button switches, open push button switches, close push button switches, and emergency call button switches, have a push button exposed on the front plate of the elevator car and a printed circuit board provided in a position facing the back surface of the push button. On the printed circuit board, a switch body that turns ON when the push button is operated and detection means for detecting a user's finger or the like located a predetermined distance away from the push button are attached.

[0004] The push button has a detection area that detects a user's finger or the like located at a predetermined distance from the push button. The detection area is set in a spatial area including a position that is a first predetermined distance horizontally away from the front panel to a position that is a second predetermined distance horizontally away. The detection means described above detects that a user's fingertip has reached the detection area. When the detection means detects that the fingertip has reached the detection area, the elevator's destination floor can be registered, the elevator can be opened or closed, or an emergency call can be made to the outside.

[0005] [Patent Document 1] Patent No. 6841372 Summary of the Invention [Problem to be solved by the invention]

[0006] In the elevator operation device described above, a push button, a printed circuit board, a switch body, and a detection means are provided for each destination floor. Therefore, in a case where there are many destination floors, such as in a high-rise building, the number of push buttons, printed circuit boards, switch bodies, and detection means also increases, which may lead to a complex configuration of the device and an increase in size. In other words, the more the numbers increase, the more complex the configuration of the device becomes, and there is a concern that the device may become larger. Furthermore, in the elevator operation device described above, when the fingertip moves quickly, there is a possibility that the fingertip may unintentionally touch the push button. Therefore, since the fingertip may touch the push button, there is room for improvement in terms of hygiene.

[0007] An object of the present disclosure is to provide an operation input device that maintains a simple configuration and prevents the device from becoming larger even when the numbers increase, and that is excellent in terms of hygiene. [Means for solving the problem]

[0008] An operation input device according to one aspect of the present disclosure includes a display device that irradiates light to display numbers, an aerial imaging device that reflects light from the display device multiple times to display an operation screen including the numbers as virtual images in the air, and a sensor that detects an object approaching the numbers. The operation input device includes a recognition unit that recognizes whether or not a number has been pressed based on the position of the object detected by the sensor, and a signal output unit that outputs a control signal corresponding to the number to an external device of the operation input device when the recognition unit recognizes that the number has been pressed, and controls the operation of the device. On the operation screen, multiple single-digit numbers are displayed, and it is possible to press a number twice. The recognition unit recognizes that the number 10×X+Y has been input when the number pressed the first time is X (X is a single-digit natural number) and the number pressed the second time is Y (Y is a single-digit natural number). The signal output unit outputs a control signal corresponding to the number 10×X+Y to the device.

[0009] In this operation input device, the display device irradiates light to display numbers, and the aerial imaging device reflects the light from the display device multiple times to display an operation screen including the numbers as a virtual image in the air. Therefore, since the operation screen displayed in the air as a virtual image is operated, the operation input device can be excellent in terms of hygiene. The operation input device has a sensor that detects an object approaching the numbers displayed in the air, a recognition unit that recognizes whether the numbers have been pressed based on the position of the object detected by the sensor, and a signal output unit that outputs a control signal corresponding to the numbers to an external device when the recognition unit recognizes that the numbers have been pressed. Therefore, since the external device can be operated by the object approaching the numbers displayed in the air, the device can be operated hygienically without touching a physical button. It is possible to press a number twice on the operation screen, and the recognition unit recognizes that the number 10×X+Y has been input when the number pressed the first time is X (X is a single-digit number) and the number pressed the second time is Y (Y is a single-digit number). Then, the signal output unit outputs a control signal corresponding to the number 10×X+Y to the device. Therefore, even when input of a two-digit number is required, only a single-digit number needs to be displayed on the operation screen, so that a simple configuration can be maintained and the size of the operation input device can be prevented from increasing.

[0010] An operation input device according to another aspect of the present disclosure includes a display device that irradiates light to display numbers, an aerial imaging device that reflects the light from the display device multiple times to display an operation screen including the numbers as virtual images in the air, and a sensor that detects an object approaching the numbers. The operation input device includes a recognition unit that recognizes whether or not a number has been pressed based on the position of the object detected by the sensor, and a signal output unit that outputs a control signal corresponding to the number to an external device of the operation input device when the recognition unit recognizes that the number has been pressed, and controls the operation of the device. On the operation screen, a first number group including a plurality of single-digit numbers and a second number group including the number (Z×10) (Z is a single-digit natural number) are displayed, and it is possible to press the numbers of the first number group and the second number group. The recognition unit recognizes that the number N+M has been input when the number pressed in the first number group is M (M is a single-digit natural number) and the number pressed in the second number group is N (N is the number Z×10). The signal output unit outputs a control signal according to the number N+M to the device.

[0011] In this operation input device, as in the above-mentioned operation input device, an operation screen displayed in the air as a virtual image is operated, and an external device can be operated by approaching an object to the number displayed in the air, so that the operation input device can be excellent in terms of hygiene. On the operation screen, a first number group including a plurality of single-digit numbers and a second number group including the number (Z×10) are displayed. On the operation screen, it is possible to press the numbers of the first number group and the numbers of the second number group. When M (M is a single-digit natural number) of the first number group and N (N is a natural number satisfying Z×10) of the second number group are pressed, the recognition unit recognizes that the number N+M has been input. Then, the signal output unit outputs a control signal corresponding to the number N+M to the device. Therefore, even if a two-digit number needs to be input, it is only necessary to display the single-digit number of the first number group and the number (Z×10) of the second number group as the operation screen, so that a simple configuration can be maintained and the operation input device can be prevented from becoming large.

[0012] The operation input device may further include a contact button including a plurality of single-digit numbers. The recognition unit may recognize whether or not a number on the contact button has been pressed. In this case, by further including the contact button, even a visually impaired person who is blind can operate the device by pressing the contact button. Effect of the Invention

[0013] According to the present disclosure, even if the numbers increase, a simple configuration can be maintained and an increase in size of the device can be suppressed, making it possible to provide an operation input device that is excellent in terms of hygiene.

[0015] Hereinafter, an embodiment of an operation input device according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are given the same reference numerals, and duplicated descriptions are omitted as appropriate. In addition, the drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios and the like are not limited to those shown in the drawings.

[0016] Fig. 1 is a vertical cross-sectional view showing a schematic diagram of an elevator system 1, which is an example of equipment to which the operation input device according to this embodiment is applied. As shown in Fig. 1, the elevator system 1 is provided inside a building S having a floor U and a wall V. The elevator system 1 includes an elevator car 2 in which a user M of the elevator system 1 rides, a wire rope 3 for suspending the elevator car 2, and elevator doors 4 provided on each floor of the building S.

[0017] The elevator system 1 has landings 5 ​​provided on each floor of a building S, and a space 6 in which an elevator car 2 is arranged. When viewed from the elevator door 4, the space 6 is a space provided on the opposite side of the landings 5. The elevator car 2 moves up and down in the space 6 by winding up and down a wire rope 3.

[0018] For example, the operation input device 10A is provided in the internal space 2b of the elevator car 2, and the operation input device 10B is provided at the landing 5. A portion of the configuration of the operation input device 10A is the same as a portion of the configuration of the operation input device 10B. Therefore, hereinafter, when describing a common configuration of the operation input device 10A and the operation input device 10B, the operation input device 10A and the operation input device 10B will be collectively described as the operation input device 10.

[0019] FIG. 2 is a perspective view showing the operation input device 10. As shown in FIG. 2, the operation input device 10 has a columnar shape extending in the vertical direction D1. The operation input device 10 includes a columnar portion 11 extending in the vertical direction D1, and a support portion 12 supporting the columnar portion 11 at the lower end of the columnar portion 11. The support portion 12 extends so as to widen from the lower end of the columnar portion 11. The support portion 12 has, for example, a plate shape. The support portion 12 enables the operation input device 10 to be stably erected.

[0020] The pillar-shaped portion 11 has, for example, a pentagonal pillar shape. More specifically, the pillar-shaped portion 11 has a quadrangular pillar-shaped portion 11A and a triangular pillar-shaped portion 11B. The operation input device 10 (operation input device 10A) is arranged such that a corner portion 11b of the triangular pillar-shaped portion 11B, which is provided at a position separated from the quadrangular pillar-shaped portion 11A, faces a corner portion 2c of the internal space 2b of the elevator car 2. This allows the operation input device 10 to be arranged comfortably in the internal space 2b of the elevator car 2.

[0021] The columnar portion 11 has a front portion 13 facing a user M who has entered the internal space 2b of the elevator car 2, a side portion 14 facing a direction intersecting with the front portion 13, and a top surface portion 15 facing upward. The front portion 13 extends in a vertical direction D1 and a first direction D2 intersecting with the vertical direction D1. The side portion 14 extends in a second direction D3 intersecting with both the vertical direction D1 and the first direction D2, and in the vertical direction D1. For example, the operation input device 10 has an air vent 17 communicating with the inside of the columnar portion 11 and a speaker 18 that outputs sound. The air vent 17 is provided in the side portion 14, and the speaker 18 is provided in the front portion 13. The air vent 17 and the speaker 18 will be described in detail later.

[0022] Top surface 15 faces obliquely upward toward the near side (hereinafter, may be simply referred to as "near side") when viewed from user M facing operation input device 10. This allows top surface 15 to be easily visible to user M. Top surface 15 has rectangular portion 15A and triangular portion 15B, and corner 15b of triangular portion 15B, which is provided at a position spaced apart from rectangular portion 15A, faces corner 2c of internal space 2b.

[0023] For example, the operation input device 10 includes a plate-like member 16 attached to the top surface portion 15 by an attachment member 19. As one example, the plate-like member 16 is a transparent plate on which letters are provided. For example, a guide to each floor of the building S is displayed on the plate-like member 16. The attachment member 19 is, for example, a pin that is fixed to the plate-like member 16 and screwed into the top surface portion 15. The operation input device 10 includes a plurality of attachment members 19 that are arranged on corners of the plate-like member 16, for example.

[0024] The operation input device 10 has an aerial imaging device 31 that displays an operation screen 20 including numbers 21 in the space in front of the operation input device 10. A user M specifies the destination floor of the elevator car 2 by pressing the numbers 21 on the operation screen 20 displayed in the space. For example, in addition to the multiple numbers 21, the operation screen 20 displays buttons such as an open button for keeping the elevator doors 4 open, a close button for closing the elevator doors 4, and an emergency button for reporting an emergency to the control room of the elevator system 1. However, these buttons are not shown in FIG. 2.

[0025] 3 is a vertical cross-sectional view of the operation input device 10 showing the internal structure of the operation input device 10 including the aerial imaging device 31. As shown in Fig. 2 and Fig. 3, the operation input device 10 includes the aerial imaging device 31 that displays an operation screen 20 with numbers 21, a sensor 32 that detects an object M1 such as a finger of a user M approaching the numbers 21, a display device 40 disposed inside the columnar part 11, and a control unit 50. The control unit 50 is, for example, a control board that controls the operation of the operation input device 10.

[0026] The aerial imaging device 31 and the display device 40 correspond to a virtual image display unit that displays the operation screen 20 as a virtual image. For example, each of the aerial imaging device 31 and the display device 40 has a plate shape. The aerial imaging device 31 is inclined with respect to the vertical direction D1 so as to extend toward the front as it extends downward. The display device 40 is inclined with respect to the vertical direction D1 so as to extend toward the front as it extends upward. The upper end of the aerial imaging device 31 and the upper end of the display device 40 are, for example, close to each other.

[0027] The aerial imaging device 31 is, for example, a retroreflective member (retroreflective mirror) disposed inside an opening 13b formed in the front portion 13 of the columnar portion 11. The aerial imaging device 31 is disposed obliquely so as to move upward from the lower end of the opening 13b toward the rear side (the rear side as viewed from the user M facing the operation input device 10; hereinafter, sometimes simply referred to as the "rear side").

[0028] The sensor 32 is provided, for example, on the upper part of the aerial imaging device 31. The sensor 32 is fixed to the lower part of the top surface part 15. The sensor 32 is, for example, an area sensor. In this case, the sensor 32 has a two-dimensional detection area 32b corresponding to the operation screen 20, and detects that an operation has been performed on the operation screen 20 when the target object M1 reaches the detection area 32b.

[0029] The operation screen 20 includes a numeric keypad on which single-digit numbers 21 from "1" to "9" are arranged. Each number 21 is displayed, for example, surrounded by a frame portion 22. The detection area 32b has detection areas corresponding to each of the numbers 21 from "1" to "9". As an example, the detection area 32b is provided parallel to the operation screen 20. For example, the detection area 32b is provided on the front side of the operation screen 20, and the detection area 32b includes detection areas corresponding to each number 21 and each button. By providing the detection area 32b on the front side of the operation screen 20 in this way, the operability of the operation screen 20 can be improved.

[0030] As an example, a detection area corresponding to the number "K" 21 (K is a natural number between 1 and 9) on the operation screen 20 is provided in front of the number "K" displayed as a virtual image. The sensor 32 detects that the number "K" 21 has been pressed when an object M1 approaching the number "K" 21 reaches the detection area.

[0031] The operation input device 10 includes, for example, a housing 35 in which the aerial imaging device 31, the sensor 32, and the display device 40 are incorporated. The housing 35 holds the aerial imaging device 31, the sensor 32, and the display device 40 while maintaining the positional relationship between the aerial imaging device 31, the sensor 32, and the display device 40 described above. The housing 35 holding the aerial imaging device 31, the sensor 32, and the display device 40 is incorporated inside the opening 13b of the columnar section 11. For example, the housing 35 has a triangular shape in a side view (when viewed from the first direction D2).

[0032] The control unit 50 is disposed, for example, below the aerial imaging device 31 and the display device 40. For example, a space 36 is formed between the housing 35 and the control unit 50. As an example, the control unit 50 is disposed so as to extend in the first direction D2 and the second direction D3.

[0033] The control unit 50 is a circuit board on which a circuit for controlling the operation of the display device 40 is mounted. The control unit 50 is electrically connected to the sensor 32, and receives an operation signal from the sensor 32 indicating that the operation screen 20 has been operated. The control unit 50 is electrically connected to the display device 40, and controls the screen display by the display device 40 by outputting a display control signal to the display device 40.

[0034] A space 37 is formed between the display device 40 and the top surface portion 15. Since the operation input device 10 has the space 37 located above the display device 40 and below the top surface portion 15, the space 37 can be effectively used as a space for dissipating heat from the display device 40. The space 37 is defined by the top surface portion 15, the display device 40, and a pair of side surface portions 14. A plurality of ventilation holes 17 penetrating in the first direction D2 are formed in the portion defining the space 37 of each side surface portion 14. The space 37 and the plurality of ventilation holes 17 allow heat from the display device 40 to escape to the outside of the operation input device 10.

[0035] Fig. 4 is a diagram showing a display device 40 of the operation input device 10A provided in the internal space 2b of the elevator car 2. Fig. 5 is an exploded perspective view of the display device 40. As shown in Figs. 4 and 5, the display device 40 includes, for example, a light source 41, a substrate 42, a panel base 43, a diffusion sheet 44, a panel member 45, an anti-peep sheet 46, and a pressing member 47. The light source 41 is mounted on the substrate 42. The substrate 42, the panel base 43, the diffusion sheet 44, the panel member 45, the anti-peep sheet 46, and the pressing member 47 are overlapped so as to be arranged in this order.

[0036] The light source 41 is, for example, an LED light source. For example, the display device 40 has a plurality of light sources 41, and a light source 41 is provided for each number 21 to be displayed in the air. In this embodiment, a numeric keypad with the numbers 21 from "1" to "9" arranged is displayed as the operation screen 20, so nine light sources 41 are mounted on the substrate 42.

[0037] The substrate 42 has, for example, a rectangular shape. Three light sources 41 are arranged along one side of the substrate 42, and three light sources 41 are arranged along another side of the substrate 42 perpendicular to the one side. The substrate 42 contains, for example, aluminum. As an example, the substrate 42 is an aluminum substrate. In this case, it is possible to improve the dissipation of heat from the light sources 41 mounted on the substrate 42.

[0038] The panel base 43 is interposed between the substrate 42 and the diffusion sheet 44. For example, the substrate 42 is fixed to the panel base 43 by screws 42b. The panel base 43 is provided to narrow the light from each light source 41 and to suppress leakage of the light. The panel base 43 is configured, for example, by covering a resin layer with an aluminum layer. That is, the panel base 43 is configured by applying aluminum plating to the resin. Therefore, the light from the light source 41 can be efficiently reflected by the panel base 43.

[0039] The panel base 43 has, for example, a plate shape as a whole. The panel base 43 has, for example, a rectangular shape. The panel base 43 has recesses 43b recessed in the thickness direction of the panel base 43. The panel base 43 has a plurality of recesses 43b recessed from a surface 43c facing the side opposite to the substrate 42 (the diffusion sheet 44 side).

[0040] A recess 43b is provided, for example, for each number 21 displayed in the air. Therefore, the panel base 43 has nine recesses 43b, similar to the light source 41. Three recesses 43b are lined up along one side of the panel base 43, and three recesses 43b are lined up along the other side perpendicular to the one side.

[0041] The area of ​​the recess 43b when viewed in the thickness direction of the panel base 43 decreases with increasing distance from the surface 43c. In other words, the cross-sectional area of ​​the recess 43b when cut along the in-plane direction of the surface 43c of the panel base 43 decreases with increasing distance from the surface 43c.

[0042] The diffusion sheet 44 is interposed between the panel base 43 and the panel member 45. The diffusion sheet 44 diffuses the light emitted from the light source 41 through the panel base 43. By providing the diffusion sheet 44, even if the light source 41 is an LED light source and the light from the light source 41 has a strong directivity, the directivity can be alleviated.

[0043] The panel member 45 is interposed between the diffusion sheet 44 and the anti-snooping sheet 46. The panel member 45 converts the light transmitted through the diffusion sheet 44 into the shape of the number 21. The panel member 45 has a transmissive portion 45b that transmits the light from the light source 41 and a non-transmissive portion 45c that does not transmit the light from the light source 41.

[0044] The transparent portion 45b includes a number portion 45d for displaying the number 21 and a frame portion 45f surrounding the number portion 45d. The frame portion 45f has, for example, a first frame portion 45g surrounding the number portion 45d and a second frame portion 45h surrounding the first frame portion 45g. Each of the first frame portion 45g and the second frame portion 45h has, for example, a rectangular shape. As an example, the frame portion 45f has a diagonal line portion 45j extending from a corner of the first frame portion 45g to a corner of the second frame portion 45h. The transparent portion 45b includes a plurality of number portions 45d and a plurality of frame portions 45f.

[0045] The number portion 45d and the frame portion 45f are provided for each number 21 and frame portion 22 displayed in the air. The number portion 45d and the frame portion 45f of the panel member 45 are made into the transparent portion 45b, and the portion of the panel member 45 other than the number portion 45d or the frame portion 45f is made into the non-transparent portion 45c. Since the number portion 45d and the frame portion 45f are made into the transparent portion 45b, the number 21 and the frame portion 22 are displayed in front of the aerial imaging device 31 as if they are popping out.

[0046] The panel member 45 is produced, for example, by irradiating a part of a transparent panel that is painted black with laser light. The part of the panel member 45 that is irradiated with the laser light is the transparent portion 45b, and the part of the panel member 45 that is not irradiated with the laser light is the non-transparent portion 45c.

[0047] The anti-peep sheet 46 is interposed between the panel member 45 and the pressing member 47. The anti-peep sheet 46 is provided to prevent peeping by narrowing the irradiation area of ​​the light from the panel member 45. The anti-peep sheet 46 has a configuration in which, for example, light-transmitting parts that transmit the light from the panel member 45 and a plurality of wall parts that are opaque to the light from the panel member 45 are arranged alternately.

[0048] As an example, the anti-peep sheet 46 is a blind sheet. For example, the display device 40 has two anti-peep sheets 46. In this case, the height (thickness) of the wall of the anti-peep sheet 46 can be ensured, so that the light from the panel member 45 can be more reliably narrowed down.

[0049] The pressing member 47 is provided on the opposite side of the anti-peep sheet 46 to the panel member 45. The pressing member 47 sandwiches, for example, the diffusion sheet 44, the panel member 45 and the anti-peep sheet 46 together with the panel base 43. The pressing member 47 has a plate-shaped portion 47c in which a plurality of openings 47b that transmit light from the anti-peep sheet 46 are formed, and a plurality of side portions 47f that protrude from the outer edge of the plate-shaped portion 47c in the thickness direction of the plate-shaped portion 47c.

[0050] The anti-snooping sheet 46, the panel member 45, the diffusion sheet 44, and a part of the panel base 43 fit into the area of ​​the pressing member 47 defined by the plate-shaped portion 47c and the multiple side portions 47f. The pressing member 47 has a protruding portion 47g protruding from the side portion 47f in the thickness direction of the plate-shaped portion 47c, and a hole 47h penetrating the protruding portion 47g.

[0051] For example, a screw hole 43f is formed in a side surface 43d of the panel base 43. The pressing member 47 is fixed to the panel base 43 by fastening screws into holes 47h of the pressing member 47, which houses the anti-snooping sheet 46, the panel member 45, and the diffusion sheet 44, and into the screw holes 43f of the panel base 43.

[0052] The above describes the display device 40 of the operation input device 10A provided in the internal space 2b of the elevator car 2. A portion of the configuration of the display device in the operation input device 10B provided in the hall 5 is the same as a portion of the configuration of the display device 40 in the operation input device 10A. For example, as shown in Figures 6(a) and 6(b), the display devices 40A and 40B of the operation input device 10B have a panel member and a pressing member different from the panel member 45 and the pressing member 47.

[0053] As an example, Fig. 6(a) shows a display device 40A of an operation input device 10A arranged at a landing 5 on the first floor of a building S, and Fig. 6(b) shows a display device 40B of an operation input device 10B arranged at a landing 5 on a floor other than the first floor of a building S. The display device 40A has a panel member 45A different from the panel member 45 and a pressing member 47A different from the pressing member 47.

[0054] The panel member 45A converts the light transmitted through the diffusion sheet 44 into the shape of an upward arrow 45k. In the panel member 45A, the transmission portion 45b has an arrow 45k for displaying the upward arrow as the operation screen 20, and a frame portion 45p surrounding the arrow 45k. The arrow 45k and the frame portion 45p are formed as the transmission portion 45b, so that the upward arrow is displayed as if it is protruding forward of the aerial imaging device 31. The pressing member 47A has a plate-shaped portion 47k in which an opening 47j that transmits light from the anti-peep sheet 46 is formed, and a side portion 47f. The opening 47j has, for example, a vertically long rectangular shape in an area including the center of the plate-shaped portion 47k.

[0055] In the display device 40B, the transmission portion 45b has an arrow 45k for displaying an upward arrow as the operation screen 20, a frame portion 45p surrounding the arrow 45k, an arrow 45q for displaying a downward arrow as the operation screen 20, and a frame portion 45r surrounding the arrow 45q. In the case of the panel member 45B, an upward arrow and a downward arrow are displayed as if they are raised on the front side of the aerial imaging device 31. The pressing member 47B has a plate-shaped portion 47q in which two openings 47p that transmit light from the anti-peep sheet 46 are formed, and a side portion 47f. The two openings 47p are formed so as to be aligned vertically in the plate-shaped portion 47k.

[0056] As described above, a space 37 is formed between the display device 40 and the top surface portion 15, and a cooling fan 60 is disposed in the space 37. Fig. 7 is a perspective view showing a configuration of a portion of the space 37 where the cooling fan 60 is disposed. Note that the illustration of the cooling fan 60 is simplified in Fig. 7. For example, the operation input device 10 includes a back surface portion 61 facing the side opposite to the front surface portion 13, and a fan attachment portion 62 extending from an end of the back surface portion 61 in the first direction D2 to the near side.

[0057] The operation input device 10 has a pair of fan mounting parts 62 aligned along the first direction D2, and each fan mounting part 62 is provided inside each ventilation hole 17 (see FIG. 2). A cooling fan 60 can be attached to the fan mounting parts 62, for example, by screws. By attaching the cooling fan 60 in this manner, heat from the display device 40 (substrate 42) can be efficiently dissipated by the cooling fan 60 to the outside in the first direction D2 of the operation input device 10.

[0058] Fig. 8 is a perspective view showing the plate-shaped member 16 and the top surface portion 15 of the operation input device 10A disposed in the internal space 2b of the elevator car 2. Fig. 9 is a perspective view showing the operation input device 10A with the plate-shaped member 16 and the top surface portion 15 removed. As shown in Figs. 8 and 9, the operation input device 10A includes an illuminance sensor 70.

[0059] Top surface 15 of operation input device 10A has an opening 15c through which illuminance sensor 70 is exposed. Opening 15c is formed, for example, in triangular portion 15B of top surface 15. Illuminance sensor 70 has a sensor main body 71 that detects the illuminance in internal space 2b of elevator car 2, a board 72 on which sensor main body 71 is mounted, a board fixing portion 73 provided inside triangular column portion 11B of column portion 11, and a fixing member 74 that fixes board 72 to board fixing portion 73.

[0060] The substrate 72 has, for example, a through hole 72b, and the substrate fixing portion 73 has a screw hole 73b. The fixing member 74 is, for example, a screw that is inserted into the through hole 72b and screwed into the screw hole 73b. As an example, a harness (not shown) extends downward from the substrate 72, and the substrate fixing portion 73 has a recess 73c into which the harness fits. The sensor body 71 and the substrate 72 are electrically connected to the control unit 50 via the harness.

[0061] The illuminance sensor 70 (sensor body 71) detects the illuminance in the internal space 2b of the elevator car 2, and outputs an illuminance signal indicating information on the detected illuminance to the control unit 50. When the control unit 50 receives the illuminance signal, it determines whether the illuminance in the internal space 2b is equal to or greater than a certain value. When the illuminance in the internal space 2b is equal to or greater than a certain value, the control unit 50 outputs a display control signal to the display device 40, and the display device 40 displays the operation screen 20 in the air via the aerial imaging device 31. On the other hand, when the illuminance in the internal space 2b is not equal to or greater than a certain value, the control unit 50 switches the operation input device 10A to an energy saving mode. This makes it possible to reduce the power consumption of the operation input device 10A.

[0062] Fig. 10 is an exploded perspective view of the speaker 18 showing the configuration of the speaker 18 provided on the front part 13. As shown in Fig. 10, the speaker 18 has a cone 18b, an annular stopper 18c, an annular cushion sponge 18d, a screw 18f, a plate 18g, and a bracket 18h provided inside the front part 13. The cone 18b, the stopper 18c, and the cushion sponge 18d are stacked in this order, and the cone 18b fits into a hole 18j formed in the bracket 18h.

[0063] The stopper 18c has a through hole 18k through which the screw 18f is inserted, and the bracket 18h has a screw hole 18p through which the screw 18f is screwed. The screw 18f is inserted through the cushion sponge 18d and the through hole 18k and screwed into the screw hole 18p to fix the stopper 18c and the cushion sponge 18d to the bracket 18h. The plate 18g has a plurality of through holes 18q. The operation input device 10 is capable of communicating with an external device of the operation input device 10, and can output a sound input from the external device from the through hole 18q of the plate 18g of the speaker 18.

[0064] For example, the operation input device 10B arranged at the boarding area 5 includes a human presence sensor 80. The human presence sensor 80 is provided, for example, on the front portion 13. As one example, the human presence sensor 80 is arranged above the speaker 18. The human presence sensor 80 detects a person by, for example, emitting infrared rays and detecting the infrared rays reflected from the person.

[0065] The human presence sensor 80 is electrically connected to the control unit 50. The human presence sensor 80 detects a person at the boarding station 5, and outputs a human detection signal indicating that a person has been detected to the control unit 50. Upon receiving the human detection signal, the control unit 50 outputs a display control signal to the display device 40, and the display device 40 displays the operation screen 20 in the air via the aerial imaging device 31. In this way, when a person approaches the boarding station 5, the operation screen 20 displayed in the air can be displayed to the person, thereby making it possible to provide an operation input device 10B with even higher operability.

[0066] Next, the function of the control unit 50 will be described. Fig. 11 is a functional block diagram of the control unit 50. The control unit 50 is capable of communicating with each of the sensor 32 and the display device 40. The control unit 50 includes, for example, a CPU (Central Processing Unit) that executes a program implemented in the operation input device 10, a storage unit including a ROM (Read Only Memory) and a RAM (Random Access Memory), an input / output unit, and a driver. Each function of the control unit 50 is realized by operating the input / output unit under the control of the CPU and reading or writing data in the storage unit.

[0067] The control unit 50 has, as functional components, a recognition unit 51 and a signal output unit 52. For example, when the sensor 32 detects the object M1, it outputs position data indicating the position of the object M1 to the recognition unit 51. The recognition unit 51 recognizes that the operation screen 20 has been pressed by the object M1 based on the position data output from the sensor 32.

[0068] The recognition unit 51 recognizes which number 21 has been pressed, which button (e.g., an open button, a close button, or an emergency button) has been pressed, or which arrow (e.g., an up arrow or a down arrow) has been pressed, based on the position of the object M1 in the detection area 32b of the sensor 32. The signal output unit 52 generates a control signal according to the recognition result of the recognition unit 51, and outputs the generated control signal to a device external to the operation input device 10. In this embodiment, the signal output unit 52 outputs the generated control signal to the elevator system 1.

[0069] For example, when the recognition unit 51 recognizes that the number 21 has been pressed as a destination floor, the signal output unit 52 outputs a control signal corresponding to the number 21 to the elevator system 1. Upon receiving the control signal, the elevator system 1 moves the elevator car 2 to the destination floor indicated by the number 21.

[0070] For example, when the recognition unit 51 recognizes that a button such as an open button, a close button, or an emergency button on the operation screen 20 has been pressed, the signal output unit 52 outputs a control signal corresponding to the button to the elevator system 1. When the elevator system 1 receives the control signal, it performs the operation indicated by the button. Specifically, when the elevator system 1 receives a control signal indicating that the open button has been pressed, it keeps the elevator doors 4 open, and when it receives a control signal indicating that the close button has been pressed, it performs control to close the elevator doors 4. Furthermore, when the elevator system 1 receives a control signal indicating that the emergency button has been pressed, it notifies the elevator system 1 control room that an emergency has occurred.

[0071] 2 and 11, a plurality of single-digit numbers 21 are displayed on the operation screen 20. When the pressed number is X (X is a single-digit natural number), the recognition unit 51 recognizes that the number X has been input. At this time, the signal output unit 52 outputs a control signal corresponding to the number X 21 to the elevator system 1. Then, the elevator system 1 moves the elevator car 2 to the X floor of the building S.

[0072] In the operation input device 10, the number 21 can be pressed multiple times. When the number 21 pressed the first time is X and the number 21 pressed the second time is Y (Y is a single-digit natural number), the recognition unit 51 recognizes that the number 10×X+Y has been input. At this time, the signal output unit 52 outputs a control signal corresponding to the number 10×X+Y to the elevator system 1. Then, the elevator system 1 moves the elevator car 2 to the 10×X+Y floor of the building S.

[0073] Furthermore, when the number 21 pressed the first time is X, the number 21 pressed the second time is Y, and the number pressed the third time is W (W is a single-digit natural number), the recognition unit 51 recognizes that the numbers 100×X+10×Y+W have been input. At this time, the signal output unit 52 outputs a control signal corresponding to the numbers 100×X+10×Y+W to the elevator system 1. Then, the elevator system 1 moves the elevator car 2 to the 100×X+10×Y+W floor of the building S.

[0074] Next, the effects obtained from the operation input device 10 according to this embodiment will be described. In the operation input device 10, the display device 40 irradiates light to display numbers (e.g., the number portion 45d), and the aerial imaging device 31 reflects the light from the display device 40 multiple times to display the operation screen 20 including the numbers 21 as a virtual image in the air. Therefore, since the operation screen 20 displayed as a virtual image in the air is operated, the operation input device 10 can be excellent in terms of hygiene.

[0075] The operation input device 10 has a sensor 32 that detects an object M1 approaching a number 21 displayed in the air, a recognition unit 51 that recognizes whether or not the number 21 has been pressed based on the position of the object M1 detected by the sensor 32, and a signal output unit 52 that outputs a control signal corresponding to the number 21 to an external device, the elevator system 1, when the recognition unit 51 recognizes that the number 21 has been pressed. Therefore, the elevator system 1 can be operated by the object M1 approaching the number 21 displayed in the air, so that the elevator system 1 can be operated hygienically without touching a physical button.

[0076] It is possible to press the number 21 twice on the operation screen 20, and when the number 21 pressed the first time is X and the number 21 pressed the second time is Y, the recognition unit 51 recognizes that the number 10×X+Y has been input. Then, the signal output unit 52 outputs a control signal corresponding to the number 10×X+Y to the elevator system 1. Therefore, even when input of a two-digit number is required, it is sufficient to display only a one-digit number 21 on the operation screen 20, so that a simple configuration can be maintained and an increase in size of the operation input device 10 can be suppressed.

[0077] Next, various modified examples of the operation input device according to the present disclosure will be described. Fig. 12 is a diagram showing an operation screen 20A displayed by an aerial imaging device of the operation input device according to the first modified example. Since a part of the configuration of the operation input device according to the modified example is the same as a part of the configuration of the operation input device 10 described above, the description of the parts that overlap with the configuration of the operation input device 10 will be omitted as appropriate below.

[0078] On the operation screen 20A, a first group of numbers 23 including a plurality of single-digit numbers 21 and a second group of numbers 25 including a number 24 (Z×10) (Z is a single-digit natural number) are displayed. Furthermore, on the operation screen 20A, an open button 26, a close button 27, and an emergency button 28 are displayed. The functions of the open button 26, the close button 27, and the emergency button 28 are the same as the functions of the open button, the close button, and the emergency button in the operation input device 10 described above.

[0079] On the operation screen 20A, it is possible to press the number 21 of the first number group 23 and the number 24 of the second number group 25. When the number 21 pressed in the first number group 23 is M (M is a single-digit natural number) and the number 24 pressed in the second number group 25 is N (N is a natural number that satisfies Z×10), the recognition unit 51 recognizes that the number N+M has been input. At this time, the signal output unit 52 outputs a control signal corresponding to the number N+M to the elevator system 1. Then, the elevator system 1 moves the elevator car 2 to the N+M floor of the building S.

[0080] As described above, in the operation input device according to the first modification, similarly to the above-described operation input device 10, the operation screen 20A displayed in the air as a virtual image is operated, and the elevator system 1 can be operated by the approach of the object M1 to the numbers 21, 24 displayed in the air, so that the operation input device according to the first modification is excellent in terms of hygiene. On the operation screen 20A, a first number group 23 including a plurality of single-digit numbers 21 and a second number group 25 including the number 24 (Z×10) are displayed. On the operation screen 20A, the numbers 21 in the first number group 23 and the numbers 24 in the second number group 25 can be pressed.

[0081] When M of the number 21 in the first number group 23 and N of the number 24 in the second number group 25 are pressed, the recognition unit 51 recognizes that the number N+M has been input. Then, the signal output unit 52 outputs a control signal corresponding to the number N+M to the elevator system 1. Therefore, even when input of a two-digit number is required, it is sufficient to display the one-digit number 21 of the first number group 23 and the number 24 of (Z×10) of the second number group 25 as the operation screen 20A, so that a simple configuration can be maintained and an increase in size of the operation input device can be suppressed.

[0082] Next, an operation input device 10C according to a second modified example will be described with reference to Fig. 13. As shown in Fig. 13, the operation input device 10C includes a contact-type button 90 including a plurality of single-digit numbers 91, in addition to an aerial imaging device 31 that displays the above-described operation screen 20 in midair.

[0083] The contact-type button 90 is provided, for example, on the plate-like member 16. As an example, the contact-type button 90 includes a plurality of numbers 91, an open button 92, a close button 93, and an emergency button 94. The functions of the open button 92, the close button 93, and the emergency button 94 are the same as the functions of the open button, the close button, and the emergency button in the operation input device 10, respectively.

[0084] The contact-type button 90 is, for example, electrically connected to the control unit 50. When the number pressed on the contact-type button 90 is E (E is a single-digit natural number), the recognition unit 51 recognizes that the number E has been input. At this time, the signal output unit 52 outputs a control signal corresponding to the number E to the elevator system 1. Then, the elevator system 1 moves the elevator car 2 to the E floor of the building S.

[0085] In the contact-type button 90, for example, like the operation screen 20, it is possible to press the number 91 multiple times. When the number 91 pressed the first time is E and the number 91 pressed the second time is F (F is a single-digit natural number), the recognition unit 51 recognizes that the number 10×E+F has been input. At this time, the signal output unit 52 outputs a control signal corresponding to the number 10×E+F to the elevator system 1. Then, the elevator system 1 moves the elevator car 2 to the 10×E+F floor of the building S.

[0086] As described above, the operation input device 10C according to the second modified example further includes a contact-type button 90 including a plurality of single-digit numbers 91. The recognition unit 51 recognizes whether or not the number 91 on the contact-type button 90 has been pressed. In this case, by further including the contact-type button 90, even a visually impaired person who is blind can operate the elevator system 1 by pressing the contact-type button 90.

[0087] The above describes the embodiment and various modified examples of the operation input device according to the present disclosure. However, the operation input device according to the present disclosure is not limited to the above-described embodiment or modified example, and may be modified or applied to other things within the scope of the gist described in each claim. In other words, the configuration, shape, size, number, material, and arrangement of each part of the operation input device can be appropriately changed within the scope of the gist described above.

[0088] For example, in the above-described embodiment, the operation input device 10 provided in the elevator system 1 has been exemplified. However, the external device to be operated by the operation input device according to the present disclosure may be something other than the elevator system 1. For example, the external device may be a multi-story parking lot. In this case, too, the number 21 can be specified on the operation screen 20 displayed in the air, so that the same effect as in the above-described embodiment and modified example can be obtained.

[0089] In addition, the device as the operation target of the operation input device may be installed in a kitchen, a toilet, a water area, a hospital, a public institution, a station, an airport, or the like. For example, in an operation input device installed in a kitchen, a display screen with numbers is displayed as a virtual image in the air, making it possible to input numbers in a cooking app without directly touching the display with fingers with ingredients on them. That is, in the past, in order to touch the display of a mobile terminal or the like, one had to take the trouble of washing one's hands before entering numbers in a cooking app displayed on the display, but in the operation input device according to the present disclosure, an operation screen with numbers is displayed as a virtual image in the air, so that the cooking app can be operated by operating the numbers in the air. Therefore, since the cooking app can be operated without taking the trouble of washing one's hands, the operation input device can be made to have high operability.

[0090] For example, in an operation input device installed in an ATM, hospital, public institution, station, or airport, an operation screen with numbers is displayed as a virtual image in the air, making it possible to input numbers into an ATM, or a reception machine at a hospital or airport, without directly touching the shared display. Therefore, since it is not necessary to touch the shared display with fingers, the operation can be performed hygienically. [Explanation of symbols]
