[0011] First, an automatic door 100 to which an embodiment of the present invention is applied will be outlined with reference to Figs. 1 and 2. Fig. 1 is a front view showing an automatic door 100 according to an embodiment of the present invention. The automatic door 100 mainly comprises a door section 10 including a movable door that is controlled to open and close or driven to open and close, a controller 20 that controls the entire automatic door 100, a sensor 30 (a collective term for an activation sensor 31 and a protection sensor 32) that detects a person passing by, a door engine 40 that generates power, and a power transmission section 50 that transmits power to the door section 10. In the following description, the left-right direction in Fig. 1 is defined as the horizontal direction, and the up-down direction in Fig. 1 is defined as the vertical direction, but the automatic door 100 can be installed in any position, and the installation direction is not limited to the following example.

[0012] The door unit 10 includes a first movable door 11L and a second movable door 11R that are each provided to be movable in the horizontal direction, a first fixed door 12L and a second fixed door 12R that are provided as fixed parts at positions overlapping the first movable door 11L and the second movable door 11R when the first movable door 11L and the second movable door 11R are in an open state, and a guide mechanism 13 that guides the horizontal movement of the first movable door 11L and the second movable door 11R. The first movable door 11L, the second movable door 11R, the first fixed door 12L, and the second fixed door 12R are configured in a vertically elongated rectangular shape whose vertical dimension is larger than its horizontal dimension. When the door unit 10 is driven to open, the first movable door 11L shown on the left side in FIG. 1 is driven to the left, and the second movable door 11R shown on the right side in FIG. 1 is driven to the right. In addition, when the door unit 10 is driven to close, the first movable door 11L is driven to the right and the second movable door 11R is driven to the left, which is the opposite of the opening operation. The number and shape of the doors constituting the door unit 10 are not limited to the above and can be appropriately designed according to the needs of the installation location. Similarly, the movable direction of the door unit 10 is not limited to the horizontal direction and may be inclined from the horizontal direction.

[0013] The guide mechanism 13 includes a running rail 131, a door roller 132, a guide rail 133, and a vibration prevention part 134. The running rail 131 is a columnar rail member extending horizontally above the movable doors 11L and 11R over the entire movable range. Two door rollers 132 are provided on the upper part of each of the movable doors 11L and 11R, and each of the movable doors 11L and 11R is suspended on the running rail 131. When each of the movable doors 11L and 11R is driven to open and close in the horizontal direction, the door rollers 132 roll on the running rail 131, enabling smooth opening and closing operations. The guide rail 133 is a groove-shaped rail member extending horizontally below the movable doors 11L and 11R over the entire movable range. The vibration prevention part 134 protrudes from the lower part of the movable doors 11L and 11R and fits into the groove-shaped guide rail 133. When each of the movable doors 11L, 11R is driven to open and close horizontally, the anti-vibration portion 134 moves along the guide rail 133, thereby suppressing vibration of each of the movable doors 11L, 11R in the forward direction (perpendicular to the paper surface of FIG. 1).

[0014] Various parameters related to the opening and closing of the door section 10 can be set by the controller 20. For example, the opening and closing speed, the opening and closing strength, the opening width, etc. can be set. The opening and closing speed is the horizontal speed of the first movable door 11L and the second movable door 11R, and the directions of the speeds of both doors are opposite to each other. It is preferable that the magnitude (speed) of the speeds of both doors is equal, but they may be different. In addition, the opening and closing speed may be set to a different value between normal opening and closing and other times. For example, in the case of so-called reversal in which the door section 10 is switched to open driving to urgently avoid a pedestrian being pinched by the closing movable doors 11L, 11R during normal closing driving, the speed of the movable doors 11L, 11R during the open driving may be set to a value different from the speed during normal opening driving. In addition, the opening speed and closing speed when the door section 10 is driven by temporary power supplied from a battery in an emergency when a normal power source is not available, such as during a power outage, may be set to a value different from that during normal driving.

[0015] The opening and closing strength is the magnitude of the force when the movable doors 11L and 11R are opened and closed, and is controlled by the torque value generated by the motor 42 described later. As with the opening and closing speed described above, it is preferable that the opening and closing strength of the movable doors 11L and 11R is basically the same. Also, different opening and closing strengths may be set for normal opening and closing and other times. The opening width is typically the horizontal distance between the first movable door 11L and the second movable door 11R when the door section 10 is fully open. As shown in FIG. 1, if the moving distance between the fully closed position and the fully open position of the first movable door 11L is W1 and the moving distance between the fully closed position and the fully open position of the second movable door 11R is W2, the opening width is expressed as W1+W2. Here, the moving distances W1 and W2 can be set individually within the range of the horizontal dimension of the automatic door 100. In addition, in an emergency when the normal power source is unavailable, such as during a power outage, the opening width of the door section 10 may be made smaller than normal when the door section 10 is operated using temporary power supplied from a battery, thereby reducing power consumption caused by opening and closing the door section 10 in an emergency.

[0016] In FIG. 1, an activation sensor 31 as an optical sensor and a protection sensor 32 are provided as examples of the sensor 30. The activation sensor 31 is a photoelectric sensor provided on the surface of the blind 60 above the door section 10. The activation sensor 31 includes a plurality of light projecting sections that project light such as infrared light toward the floor surface, and a plurality of light receiving sections that receive reflected light from the floor surface. When an object such as a person approaches the automatic door 100 and blocks the light, the amount of light received by the light receiving sections changes, so that the object can be detected. Hereinafter, when the amount of light received by the light receiving sections of the activation sensor 31 changes significantly due to the object to be detected, the activation sensor 31 is said to be in a detection state. When the detection information of the activation sensor 31 in the detection state is input to the controller 20, the door section 10 is opened by driving the door engine 40. The activation sensor 31 is provided on the indoor side (for example, the front side of the paper in FIG. 1) and the outdoor side (for example, the back side of the paper in FIG. 1), and can detect a person approaching from either side. When it is necessary to distinguish between the two below, they will be referred to as the indoor side activation sensor and the outdoor side activation sensor, respectively.

[0017] The activation sensor 31 may be configured to detect a passerby by reflecting radio waves such as microwaves or ultrasonic waves. As shown in FIG. 1 as 31A, the door unit 10 may be actuated by a passerby pressing a touch plate provided on at least one of the movable doors 11L and 11R. In addition, in tourist facilities, amusement parks, and the like, it is also assumed that the door unit 10 is actuated by an operation of a facility attendant in addition to or instead of the detection and operation of a passerby. In such a case, the facility attendant can actuate the door unit 10 remotely using an operation panel provided at a position away from the door unit 10 or an operation terminal capable of communicating with the automatic door 100.

[0018] The protection sensor 32 is a photoelectric sensor provided on the first fixed door 12L and the second fixed door 12R of the door section 10. The protection sensor 32 includes a light-emitting unit provided on one of the first fixed door 12L and the second fixed door 12R, and a light-receiving unit provided on the other. The light-emitting unit and the light-receiving unit are provided at the same height from the floor surface, and the light-receiving unit receives light such as infrared light emitted horizontally from the light-emitting unit. When the door section 10 is open and a pedestrian passes through the opening and blocks the light, the amount of light received by the light-receiving unit changes, so that the pedestrian can be detected. Hereinafter, when the amount of light received by the light-receiving unit of the protection sensor 32 changes significantly due to a pedestrian or the like to be detected, the protection sensor 32 is said to be in a detection state. The main purpose of the protection sensor 32 is to provide protection against closure, and when the protection sensor 32 detects a pedestrian during the closing operation of the movable doors 11L and 11R, the controller 20 performs inversion control to stop the closing drive and switch to the opening drive. This prevents pedestrians from being caught in the closing movable doors 11L, 11R. In addition, in this closing protection control, by using the detection information of the activation sensor 31, which is also a photoelectric sensor like the protection sensor 32, in addition, the detection accuracy of pedestrians can be improved, and safety can be further improved.

[0019] The protection sensor 32 may be configured to detect passersby by reflecting radio waves such as microwaves or ultrasonic waves. The protection sensor 32 may also be provided in a location different from the fixed doors 12L, 12R. For example, it may be provided on the blind 60 like the activation sensor 31, or on the ceiling near the automatic door 100. Providing multiple such protection sensors 32 increases costs but dramatically improves safety.

[0020] The door engine 40 includes a motor drive unit 41, a motor 42, and a drive pulley 43. The motor drive unit 41 is configured as an intelligent power module (IPM) and generates a voltage or current for driving the motor 42 under the control of the controller 20. The motor 42 as a power source for generating rotational power can be configured as various known motors, but in this embodiment, it is configured as a brushless motor equipped with an encoder using a Hall element, for example. The position of the rotor of the motor 42 detected by the encoder is input to the motor drive unit 41, and a drive voltage or drive current corresponding to the position is applied to the motor 42, thereby generating a desired rotational power. The drive pulley 43, which is rotationally driven by the motor 42, is connected to the rotor of the motor 42 via a gear mechanism or the like (not shown) and rotates in conjunction with the rotor.

[0021] The power transmission unit 50 transmits the power generated by the door engine 40 to the door unit 10, and drives the movable doors 11L and 11R to open and close. The power transmission unit 50 includes a power transmission belt 51, a driven pulley 52, and a connecting member 53. The power transmission belt 51 is an annular timing belt with many teeth formed on its inner peripheral surface, and is wound around the driving pulley 43 on the right side of FIG. 1 and around the driven pulley 52 on the left side of FIG. 1. In this state, the horizontal dimension of the power transmission belt 51 is equal to the horizontal distance between the driving pulley 43 and the driven pulley 52, and is approximately the same as the horizontal dimension of the movable range of the movable doors 11L and 11R. When the driving pulley 43 is rotated by the motor 42, the driven pulley 52 rotates in conjunction with the driving pulley 43 via the power transmission belt 51.

[0022] The connecting member 53 connects the movable doors 11L and 11R to the power transmission belt 51, respectively, to drive them to open and close. Here, one movable door is connected to the upper side of the power transmission belt 51, and the other movable door is connected to the lower side of the power transmission belt 51. In the example of Fig. 1, when the power transmission belt 51 rotates counterclockwise, the first movable door 11L moves to the left and the second movable door 11R moves to the right, which is an opening operation, and when the power transmission belt 51 rotates clockwise, the first movable door 11L moves to the right and the second movable door 11R moves to the left, which is a closing operation.

[0023] In the automatic door 100 configured as described above, when the activation sensor 31 detects a person passing by, the door engine 40 generates counterclockwise rotational power under the control of the controller 20 to drive the door unit 10 to open. Furthermore, if a state in which a person passing by is not detected continues for a predetermined time after the opening drive, the door engine 40 generates clockwise rotational power under the control of the controller 20 to drive the door unit 10 to close. Furthermore, if the protection sensor 32 or the activation sensor 31 detects a person passing by during the closing drive, the controller 20 performs inversion control to switch from the closing drive to the opening drive.

[0024] FIG. 2 shows a schematic diagram of various components that can communicate with each other inside and outside the automatic door 100. The automatic door 100 has a bus 2 to which each component is connected and data communication between the components is performed. The bus 2 is configured according to any communication standard, for example, CAN (Controller Area Network). CAN is designed to allow components to communicate with each other without going through a host computer, and is widely used for transmitting control information for various systems, not just automatic doors. Each component connected to the bus 2 can transmit information to other components via the bus 2, and can selectively receive information required by itself from the information transmitted to the bus 2 by other components.

[0025] In FIG. 2, the components connected to the bus 2 are exemplified as the controller 20, the activation sensor 31, the touch plate 31A, the protection sensor 32, the operation panel 33, the authentication device 34, the electric lock controller 35, the external interface 36, and the display device 37, and all of these components constitute the automatic door 100. Note that this figure is an example of components that can be connected to the bus 2, and components that are not shown in FIG. 1 are also shown. Furthermore, the components to be provided in the actual automatic door 100 can be selected according to the purpose, and it is not necessary to provide all of the components shown in the figure. For example, in an automatic door 100 that operates the door section 10 only by detecting and operating a pedestrian, it is not necessary to provide an operation panel 33 for an attendant or the like to operate the door section 10. Conversely, in an automatic door 100 at a tourist facility or an amusement park, which operates the door section 10 only by the operation of a facility attendant, it is not necessary to provide the activation sensor 31 or the touch plate 31A for detecting and operating a pedestrian. However, the controller 20 that controls the entire automatic door 100 is an essential component in many cases.

[0026] Among the components shown in the figure, the controller 20, the activation sensor 31, the touch plate 31A, and the protection sensor 32 have been described above, so their description will be omitted. The operation panel 33 is a control panel operated by a facility attendant at a tourist facility or an amusement park to drive the door unit 10. For example, in an attraction in which a user moves between different rooms at a predetermined timing, the attendant operates the operation panel 33 in accordance with the movement timing to control the opening and closing of the door unit 10 of each room, thereby enabling the user to move smoothly. The operation panel 33 may be fixedly installed in the facility or may be portable by the attendant. In addition, the function of the operation panel 33 may be realized in an information and communication device such as a tablet or smartphone that can communicate with the controller 20 via an external interface 36 described later.

[0027] The authentication device 34 authenticates passersby who should be allowed to pass through places where a high level of security is required, such as the entrances to apartment buildings and offices. The authentication method may be password authentication by inputting a password on a keypad provided near the door unit 10, or biometric authentication using the passerby's biometric information such as a fingerprint. If the authentication by the authentication device 34 is successful, the controller 20 drives the door unit 10 to open, and the passerby can pass through the automatic door 100. If the authentication by the authentication device 34 fails, even if the activation sensor 31 detects the passerby, the controller 20 does not drive the door unit 10 to open, thereby preventing unauthorized passage of an unauthenticated passerby.

[0028] The electric lock controller 35 controls an electric lock 35A that locks the automatic door 100. The electric lock 35A includes, as a lock driving means for driving the lock between a locked position and an unlocked position, a solenoid that generates a driving force according to an energized state, for example.

[0029] The external interface 36 inputs and outputs signals to and from various external devices 36A outside the automatic door 100 by wired or wireless connection. Examples of the external devices 36A include a work terminal such as an adjustment device used by a worker who visits the site to install or maintain the automatic door 100, and a remote server or computer connected via a public information and communication network such as the Internet. The function of the image control unit of this embodiment, which will be described later, may be realized by the external device 36A outside the automatic door 100, or may be realized within the automatic door 100. When the function of the image control unit is realized by the external device 36A, it is preferable to use a server or computer installed in a backyard in the same building as the multiple automatic doors 100, where the management and control of the automatic doors 100 are centrally performed, as the external device 36A. By inputting data into the external device 36A, various settings such as control of each component of the automatic door 100 and parameter adjustment can be performed. The external device 36A can also read information from each component of the automatic door 100 and memories associated with them to perform status diagnosis and maintenance inspection of the automatic door 100. As mentioned above, the bus 2 within the automatic door 100 is configured according to the CAN standard, but if communication between the external device 36A and the external interface 36 is performed using a different standard, such as Bluetooth (registered trademark) or Wi-Fi (registered trademark), the external interface 36 functions as a protocol converter that converts signals based on one standard into signals based on the other standard.

[0030] The display device 37 has a display unit that displays image signals received from other components or the external device 36A. The display device 37 may be, for example, a display that is provided near the automatic door 100 or in a back yard in the same building as the automatic door 100 and displays the operating status of the automatic door 100. If the display device 37 has an input function such as a touch panel, various settings such as control of each component device of the automatic door 100 and parameter adjustment can be performed by touching the display. As will be described later, the display device 37 may be provided in the door section 10 of the automatic door 100, i.e., the movable doors 11L, 11R or the fixed doors 12L, 12R. In the following description, the display device 37 is assumed to be provided in the door section 10 unless otherwise specified.

[0031] The components of the automatic door 100 listed above, i.e., the controller 20, the activation sensor 31, the touch plate 31A, the protection sensor 32, the operation panel 33, the authentication device 34, the electric lock controller 35, the external interface 36, and the display device 37, can communicate with each other via the bus 2 that complies with the CAN standard. That is, each component has a built-in CAN transceiver and a CAN controller for CAN communication. In addition to these, the external interface 36 has a protocol conversion unit that converts the protocol between the communication standard used by the external device 36A and the CAN standard. As a result, the external device 36A connected to the external interface 36 can communicate with the other components of the automatic door 100 via the bus 2.

[0032] Above, an overview of the automatic door 100 has been explained with reference to Figures 1 and 2. Next, the configuration of the automatic door 100 in which the display device 37 is provided on the door section 10 will be explained. Figure 3 is an exploded perspective view of the automatic door 100 in which the display device 37 is provided on the door section 10. The display device 37 is provided on each of the four doors 12L, 11L, 11R, and 12R that make up the door section 10. Hereinafter, the doors 12L, 11L, 11R, and 12R may be collectively referred to as doors 10.

[0033] The display device 37 provided on the door 10 is composed of a plurality of rectangular display modules 70 that are elongated in the horizontal or left-right direction. In the illustrated example, the display device 37 of the door 10 is composed of eight display modules 70 arranged on the surface of the door 10 in the vertical or up-down direction without any gaps. In this configuration, almost the entire surface of the door 10 is covered with the plurality of display modules 70, but the display modules 70 or the display device 37 may be provided on a part of the surface of the door 10. For example, the display modules 70 may not be provided on the upper part of the door 10, and priority may be given to ensuring visibility on the opposite side of each door 10. However, as described later, since the display modules 70 have transparency, the visibility on the opposite side of the door 10 can be sufficiently ensured even if the display modules 70 are present. In addition, since the lower part of the door 10 is likely to be dirty or scratched and is unlikely to catch the eye of passersby even if an image is displayed on it, the display modules 70 may not be provided. Note that each display module 70 may be any shape, not limited to a rectangular shape, and may be arranged with gaps between each display module 70.

[0034] In the illustrated example in which the surface of the door 10 is covered almost entirely by a plurality of display modules 70 arranged closely together, the images displayed on each display module 70 are synchronized with each other by an image control unit described later, so that the plurality of display modules 70 can display one large composite image on the surface of the door 10. In other words, the door 10 functions as if it were one display. Furthermore, if an abnormality occurs in the image display of the display device 37, it is only necessary to repair or replace some of the defective display modules 70, and there is no need to repair or replace the entire display device 37, so that maintenance can be performed efficiently.

[0035] Each display module 70 includes a display unit 71 that is provided on the surface of the door 10 and displays an image signal, and a connector unit 72 that is provided inside the vertical frame 14 of the door 10 and acquires the image signal. That is, the display device 37 is composed of a plurality of sets (display modules 70) of the display unit 71 and the connector unit 72. The display unit 71 is preferably transparent and flexible. A transparent display unit 71 can ensure visibility on the opposite side of the door 10, and a flexible display unit 71 can improve ease of attachment to the surface of the door 10 and adhesion. A film-shaped LED (Light Emitting Diode) or OLED (Organic Light-Emitting Diode) can be used as the display unit 71 that combines such transparency and flexibility.

[0036] Although a part of the display unit 71 may become opaque due to the light emitting elements and peripheral elements mounted on the display unit 71, as long as at least a part of the display unit 71 is transparent or semi-transparent at least when the display unit 71 is not displaying an image, visibility of the opposite side of the door 10 can be ensured, and therefore in this embodiment, such a display unit 71 is also said to have transparency. Furthermore, the display unit 71 does not have to be transparent or flexible. For example, the display unit 71 may be made of a liquid crystal that is neither transparent nor flexible. In this case, visibility of the opposite side of the door 10 can be virtually ensured by displaying an image of the opposite side of the door 10 on the display unit 71.

[0037] The connector unit 72 is provided adjacent to the display unit 71 at the end of the display module 70 in the horizontal direction or the left-right direction. In the doors 12L and 11L on the left side of the figure, the connector unit 72 is provided at the left end far from the opening of the door unit 10, and in the doors 11R and 12R on the right side of the figure, the connector unit 72 is provided at the right end far from the opening of the door unit 10. In each door 10, the connector units 72 of the multiple display modules 70 are aligned vertically or vertically at a position where they overlap with the vertical frame 14. Inside the vertical frame 14, a guide unit 141 is provided along the longitudinal direction, i.e., the vertical direction, through which wiring from each connector unit 72 passes. The wiring passing through the guide unit 141 connects each connector unit 72 of the display device 37 to the bus 2 in FIG. 2. This allows each connector unit 72 to obtain an image signal from the bus 2 and display the image on the display unit 71. As will be described later, the image signal to be displayed on the display unit 71 is mainly supplied from an image control unit as the external device 36A. In this case, the image signal is transmitted through a path including the image control unit (external device 36A), the external interface 36, the bus 2, the guide unit 141 (wiring), the connector unit 72, and the display unit 71.

[0038] The vertical frame 14 of the door 10 is provided with a removable cover portion 142. The cover portion 142 is a member that is long in the vertical or up-down direction, and houses the connector portions 72 and guide portions 141 of the multiple display modules 70 inside the vertical frame 14. FIG. 4 is a cross-sectional view of the door 10 as viewed from above. The vertical frame 14, which is substantially hollow inside, is provided with a vertical frame main body 143 to which the cover portion 142 is attached from the front (lower portion in FIG. 4). The vertical frame main body 143 and the cover portion 142 are engaged with each other by two engagement portions 144, 145. At the first engagement portion 144, the front surface of the vertical frame main body 143 abuts against the rear surface of the cover portion 142, and the left side surface of the vertical frame main body 143 abuts against the right side surface of a protrusion provided on the cover portion 142, and the two are engaged with each other. At the second engagement portion 145, two protrusions of the vertical frame main body 143 provided at the upper and lower ends of the vertical frame 14 are engaged with the cover portion 142 in a state where the two protrusions come into contact with the cover portion 142. The engagement portions 144, 145 may be engaged in any manner, but may be, for example, a snap-fit ​​method.

[0039] The connector parts 72 of the multiple display modules 70 are attached to a rectangular mounting surface 146 that is long in the vertical or up-down direction. In FIG. 4, the connector parts 72 appear to be divided into left and right parts by the second engagement parts 145, but as described above, the second engagement parts 145 are provided only at the upper and lower ends of the vertical frame 14, so the connector parts 72 installed between the upper and lower ends are connected to the left and right. The connector parts 72 are connected to a display part 71 provided on the surface of the door 10 by wiring 73, and supply image signals to the display part 71. When the cover part 142 is removed, all of the connector parts 72 inside the vertical frame 14 are exposed to the outside toward the front, so that maintenance work such as inspection, repair, and replacement of each display module 70 can be performed efficiently.

[0040] The guide portion 141 is attached to a rectangular mounting surface 147 that is elongated in the vertical or up-down direction. While the mounting surface 146 of the connector portion 72 faces forward, the mounting surface 147 of the guide portion 141 faces to the side (left side in FIG. 4). In other words, the normal direction of the mounting surface 146 of the connector portion 72 and the normal direction of the mounting surface 147 of the guide portion 141 intersect, strictly speaking, are perpendicular to each other. By facing the mounting surface 147 of the guide portion 141 to the side, the internal space of the vertical frame 14 can be efficiently utilized to accommodate the guide portion 141, which occupies a larger volume than the connector portion 72. The mounting surfaces 146 and 147 are also the outer peripheral surfaces of the door gripping portion 148 that grips the door 10 of the vertical frame 14. In this way, the connector portion 72 and the guide portion 141 can be attached by utilizing the structure of the existing door gripping portion 148, so that the display device 37 can be easily installed on the door 10. As described above, the wires (not shown) from the connectors 72 pass through the guide portion 141 in the vertical direction (the direction perpendicular to the paper surface of FIG. 4).

[0041] In the illustrated example, a display module 70 consisting of a display unit 71 and a connector unit 72 is provided on the front surface of the door 10 (the bottom surface in FIG. 4), but the display module 70 may also be provided on the rear surface of the door 10 (the top surface in FIG. 4), or on both the front and rear surfaces of the door 10.

[0042] Next, an explanation will be given of image display by the display device 37 provided on the door section 10. Fig. 5 is a functional block diagram of an image control device 80 of the automatic door 100. The image control device 80 includes an image control unit 81, a detection information acquisition unit 82, a selection unit 83, and a transmission information acquisition unit 84.

[0043] The image control unit 81 is configured as an external device 36A (FIG. 2) outside the automatic door 100, and provides image signals to each display module 70 via the external interface 36 and the bus 2. As indicated by "local" in FIG. 5, the function of the image control unit 81 is realized by a server or computer provided in a backyard in the same building as one or more automatic doors 100, which centralizes management and control of the automatic doors. The function of the image control unit 81 may be realized as a component device within the automatic door 100 as shown in FIG. 2. The image control unit 81 receives an image signal to be displayed on the display device 37 from an image server 90 provided remotely or locally in the same building. Then, the image control unit 81 performs image control processing such as processing, adjustment, editing, modification, superimposition, and addition on the image signal received from the image server 90 based on various information provided by the detection information acquisition unit 82, the selection unit 83, and the transmission information acquisition unit 84, as described later, and transmits the image signal to each display module 70.

[0044] In this way, the image server 90 and the image control unit 81 each generate an image signal. There are no limitations on the type or content of the image signal each generates, but typically, the image server 90 generates image signals that are not dependent on the situation around the automatic door 100, such as advertisements and general information that should be made known to people passing by the automatic door 100, while the image control unit 81 generates additional image signals that are dependent on the situation around the automatic door 100, such as warning information, passage assistance information, opening position information, and caution area information, which will be described later. Note that when the image server 90 and the image control unit 81 are provided in the same place, there is no need to configure them as separate entities, and they can be configured as an integrated unit.

[0045] The detection information acquisition unit 82 acquires detection information from sensors that detect the situation around the automatic door 100. There is no restriction on the type, number, and installation manner of the sensors, but as exemplified in FIG. 5, various sensors such as the activation sensor 31 (including the touch plate 31A in FIGS. 1 and 2), the protection sensor 32, the door operation detection unit 821, the image sensor 822, and the brightness sensor 823 can be used. Although not shown, when these sensors are installed outside the automatic door 100, the detection information acquisition unit 82 acquires the detection information via the external interface 36 and the bus 2. For example, the detection information of the image sensor 822 of the surveillance camera outside the automatic door 100 that captures the surroundings of the automatic door 100 is provided to the detection information acquisition unit 82 from the surveillance camera as the external device 36A (FIG. 2) via the external interface 36 and the bus 2. The image control unit 81 controls the image displayed by the display unit 71 or the display device 37 installed on the door 10 of the automatic door 100 based on the detection information acquired by the detection information acquisition unit 82.

[0046] The detection information of the activation sensor 31 indicates the detection state of the activation sensor 31. That is, in the detection state where a detection target such as a person passing by the automatic door 100 is within the detection area of ​​the activation sensor 31, the detection information is generated according to a significant change in the amount of light received by the light receiving part of the activation sensor 31 due to the detection target blocking the light. On the other hand, in the non-detection state where the detection target is not within the detection area of ​​the activation sensor 31, the detection information is not generated because there is no significant change in the amount of light received by the light receiving part of the activation sensor 31. As described later, when the image control unit 81 determines that the activation sensor 31 is in the detection state based on the detection information, it performs at least one of the following controls: hiding the image displayed by the display unit 71 or the display device 37, reducing the image, moving the image toward the edge of the display unit 71 or the display device 37, and displaying an image on the opposite side of the door unit 10.

[0047] According to the detection information of the activation sensor 31, it can also be detected that the object detected by the activation sensor 31 is moving toward the door section 10. That is, since the activation sensor 31 has a plurality of light receiving sections that receive reflected light from a plurality of detection spots obtained by dividing the floor surface as a detection area into a grid pattern or the like, if the detection spot where the object is detected is moving toward the door section 10, it is known that the object is moving toward the door section 10. As will be described later, when the image control section 81 determines based on the detection information that the object detected by the activation sensor 31 is moving toward the door section 10, it performs at least one of the following controls: hiding the image displayed by the display section 71 or the display device 37, reducing the image, moving the image toward the edge of the display section 71 or the display device 37, and displaying an image on the opposite side of the door section 10.

[0048] Similarly, the detection information of the activation sensor 31 can detect an approaching person approaching the door section 10. As will be described later, when the image control section 81 determines that there is an approaching person approaching the door section 10 based on the detection information, it changes the image displayed by the display section 71 or the display device 37 for the detected approaching person.

[0049] According to the detection information of the activation sensor 31, a congestion state estimation unit can be configured to estimate the congestion state around the automatic door 100. In other words, when the number of detection spots where the detection object is detected is large, it is understood that the detection area is crowded with many detection objects. However, since the detection area of ​​the activation sensor 31 is limited, it is preferable to use the image sensor 822 and the transmission information acquisition unit 84 described later in order to estimate the congestion state in a wider area. As described later, the image control unit 81 changes the image displayed by the display unit 71 or the display device 37 according to the congestion state around the automatic door 100 estimated based on the detection information. In addition, the image control unit 81 may hide the image of the display unit 71 or the display device 37 or may lower the brightness of the image of the display unit 71 or the display device 37 when the congestion state estimated by the congestion state estimation unit is equal to or lower than a threshold value.

[0050] According to the detection information of the activation sensor 31, it is possible to detect an abnormality of a person around the automatic door 100. For example, when a detection target (person) is detected at a detection spot of the activation sensor 31 adjacent to the fixed doors 12L, 12R where people should not approach, it is possible to recognize that an abnormal state exists in which the opening movable doors 11L, 11R may collide with the detection target (person). However, since the detection area of ​​the activation sensor 31 is limited, it is preferable to use the image sensor 822 and the transmission information acquisition unit 84 described later in order to detect abnormalities in a wider area. As described later, when the image control unit 81 detects an abnormality of a person around the automatic door 100 based on the detection information, it causes the display unit 71 or the display device 37 to display attention-calling information to call the attention of the person about whom the abnormality is detected.

[0051] According to the detection information of the activation sensor 31, the operation of the movable doors 11L, 11R can also be detected. That is, when the detection information of the activation sensor 31 is input to the controller 20, the movable doors 11L, 11R are opened by the drive of the door engine 40, so the detection information of the activation sensor 31 indicates the opening operation of the movable doors 11L, 11R. In addition, since the speed and opening width of the opening operation of the movable doors 11L, 11R are preset by the controller 20, the position and speed of the movable doors 11L, 11R during the opening operation can also be detected. Furthermore, since the timing at which the movable doors 11L, 11R in the fully open position start the closing operation and the speed of the closing operation are also preset by the controller 20, the position and speed of the movable doors 11L, 11R during the closing operation can also be detected. In this way, the opening and closing operations of the movable doors 11L, 11R can be detected using the detection information of the activation sensor 31 as a trigger. In addition, when a position sensor or a speed sensor for measuring the position and speed of the movable doors 11L, 11R is provided in the door operation detection unit 821, the operation of the movable doors 11L, 11R may be detected based on the detection information. As will be described later, the image control unit 81 controls the image displayed by the display unit 71 or the display device 37 according to the operation of the movable doors 11L, 11R detected based on the detection information.

[0052] The detection information of the protection sensor 32 indicates the detection state of the protection sensor 32. That is, in the detection state where a detection target such as a person passing by the automatic door 100 is within the detection area of ​​the protection sensor 32, the detection information is generated in response to a significant change in the amount of light received by the light receiving unit of the protection sensor 32 due to the detection target blocking the light. On the other hand, in the non-detection state where the detection target is not within the detection area of ​​the protection sensor 32, there is no significant change in the amount of light received by the light receiving unit of the protection sensor 32, so no detection information is generated. As will be described later, when the image control unit 81 determines that the protection sensor 32 is in the detection state based on the detection information, it causes the display unit 71 or the display device 37 to display attention-attracting information to draw attention.

[0053] According to the detection information of the protection sensor 32, the operation of the movable doors 11L, 11R can also be detected in addition to the detection information of the activation sensor 31. That is, when the protection sensor 32 detects a person passing by during the closing operation of the movable doors 11L, 11R, the controller 20 performs reversal control to stop the closing drive and switch to the opening drive, so that the detection information of the protection sensor 32 indicates the reversal operation of the movable doors 11L, 11R. In addition, since the speed and opening width of the reversal operation of the movable doors 11L, 11R are preset by the controller 20, the position and speed of the movable doors 11L, 11R during the reversal operation can also be detected.

[0054] The image sensor 822 provides the detection information acquisition unit 82 with image information obtained by photographing the periphery of the automatic door 100 as detection information. The image sensor 822 may be provided in the automatic door 100 or in a security camera or the like outside the automatic door 100. The detection information of the image sensor 822 can detect the movement of the detection target toward the door section 10, the approaching person approaching the door section 10, the crowded state around the automatic door 100, the abnormality of the person around the automatic door 100, and the operation of the movable doors 11L and 11R, as with the detection information of the activation sensor 31. In this case, by using image recognition technology and image analysis technology based on artificial intelligence and machine learning, it is possible to individually recognize the people and objects as the detection target, and to grasp the behavior, facial expression, line of sight, clothing, attributes such as age and gender, status, and situation of each person. As will be described later, the image control unit 81 displays images and information for people around the automatic door 100 on the display unit 71 or the display device 37 based on the detection information of the image sensor 822. For example, the image control unit 81 changes the image in the line of sight of a person approaching the door unit 10 based on the detection information of the image sensor 822.

[0055] The luminance sensor 823 provides the detection information acquisition unit 82 with luminance information obtained by measuring the luminance in the vicinity of the automatic door 100 as detection information. The luminance sensor 823 may be provided on the automatic door 100, or on a wall or ceiling outside the automatic door 100. The image control unit 81 adjusts the luminance of the image displayed by the display unit 71 or the display device 37 according to the detection information of the luminance sensor 823. That is, when the luminance around the automatic door 100 is high, the luminance of the image is also increased, and when the luminance around the automatic door 100 is low, the luminance of the image is also decreased, thereby adjusting the image so that people around the automatic door 100 can properly view it. Note that since the change in luminance during a day is determined to some extent for each season, the luminance of the image may be adjusted according to the passage of time throughout the day without using the luminance sensor 823.

[0056] The selection unit 83 selects at least one person in the vicinity of the automatic door 100 based on the detection information acquired by the detection information acquisition unit 82, particularly the detection information of the image sensor 822. For example, the selection unit 83 selects a person who has the display unit 71 or the display device 37 in his / her line of sight. The image control unit 81 causes the display unit 71 or the display device 37 to display an image directed at the person selected by the selection unit 83. As described above, the detection information of the image sensor 822 can be used to grasp the behavior, facial expression, line of sight, clothing, attributes such as age and gender, status, situation, etc. of the person selected by the selection unit 83, so that the image control unit 81 can select an image or information that is likely to interest the person from the image server 90 and display it on the display unit 71 or the display device 37.

[0057] The transmission information acquisition unit 84 acquires transmission information from an information communication device 84A in the vicinity of the automatic door 100. The transmission information acquired by the transmission information acquisition unit 84 is limited to information transmitted to the image control device 80 by the information communication device 84A, such as a mobile phone, smartphone, tablet, or personal computer, used by a user in the vicinity of the automatic door 100, or information that the user has permitted the image control device 80 to acquire. The image control unit 81 controls the image displayed by the display unit 71 or the display device 37 based on the transmission information acquired by the transmission information acquisition unit 84. For example, if the transmission information acquired by the transmission information acquisition unit 84 includes information on the user's behavior, preferences, attributes such as age and gender, status, situation, etc., the image control unit 81 can select images or information that are likely to interest the user from the image server 90 and display them on the display unit 71 or the display device 37. In addition, the transmission information acquired by the transmission information acquisition unit 84 may be able to detect the congestion situation around the automatic door 100 and abnormalities of people around the automatic door 100, similar to the detection information of the activation sensor 31 and the image sensor 822. For example, when the transmitted information acquisition unit 84 acquires transmitted information from many information communication devices 84A in a short period of time, it can be seen that the area around the automatic door 100 is crowded with many people who are users of the information communication devices 84A.

[0058] Next, a specific example of image display on the display device 37 provided on the door section 10 will be described. Fig. 6 shows the situation around the automatic door 100 and images I2L, I1L, I1R, and I2R displayed on the display device 37 provided on each door 12L, 11L, 11R, and 12R of the door section 10. There are many people around the automatic door 100, and among them, a first person P1 has entered the detection area 31B of the activation sensor 31 and is approaching the automatic door 100 to pass through, with his line of sight S1 directed toward the advertisement image I1L displayed on the movable door 11L, and a second person P2's line of sight S2 directed toward the advertisement image I1R displayed on the movable door 11R. The situation and behavior of people around the automatic door 100 are detected by the image sensor 822, etc., including the first person P1 looking at the advertising image I1L on the movable door 11L while moving towards the automatic door 100, and the second person P2 looking at the advertising image I1R on the movable door 11R. In the illustrated example, in addition to the image sensor 822 and brightness sensor 823, an environment sensor 824 is provided as a sensor outside the automatic door 100 to measure environmental data such as temperature, humidity, noise, etc. around the automatic door 100, and is used for image control by the image control unit 81. For example, when the temperature is high, the image control unit 81 displays advertising images for cold drinks or ice cream on the door 10.

[0059] FIG. 7 shows an example of an image displayed for a first person P1. In FIG. 7(A), an image similar to that in FIG. 6 is displayed on each of the doors 12L, 11L, 11R, and 12R. As described above, the first person P1 is looking at the advertisement image on the movable door 11L, and the center of his field of view or visual field is indicated by S1. FIG. 7(B)-(J) show an example of an image of the movable door 11L that is changed by the image control unit 81 for the first person P1 as an approacher approaching the movable doors 11L and 11R. Here, only an example of an image of the movable door 11L is shown, but the image control unit 81 may change the image of the movable door 11R in a similar manner.

[0060] In FIG. 7(B), the image control unit 81 makes the image of the movable door 11L invisible in response to the activation sensor 31 being in a detection state due to the first person P1 in the detection area 31B. At this time, instead of the hidden image, highly visible information such as text information that does not obstruct the field of view of the first person P1 may be displayed on the movable door 11L. In FIG. 7(C), the image control unit 81 reduces the brightness of the image of the movable door 11L in response to the activation sensor 31 being in a detection state due to the first person P1 in the detection area 31B. In FIG. 7(D), the image control unit 81 reduces the image of the movable door 11L in response to the activation sensor 31 being in a detection state due to the first person P1 in the detection area 31B. In FIG. 7(E), the image control unit 81 moves the image of the movable door 11L toward the end of the movable door 11L in response to the activation sensor 31 being in a detection state due to the first person P1 in the detection area 31B. These image examples can prevent the view of the first person P1 passing through the automatic door 100 from being obstructed by advertising images, etc., thereby improving safety while passing through. Note that the images in Figures 7(B) to (E) above and the images in Figures 7(F) to (J) described below may be displayed by the image control unit 81 when the detection information acquisition unit 82 detects that the first person P1 in the detection area 31B is moving toward the movable doors 11L, 11R.

[0061] In the examples of Fig. 7(F)-(I), the image control unit 81 changes the image in the field of view S1 or on the line of sight S1 of the first person P1 who is an approaching person. In Fig. 7(F), the image control unit 81 hides the image in the field of view S1 or on the line of sight S1 of the first person P1. In Fig. 7(G), the image control unit 81 lowers the luminance of the image in the field of view S1 or on the line of sight S1 of the first person P1. In this case, the luminance of the image in the field of view S1 or on the line of sight S1 may be gradually lowered as the first person P1 approaches the movable door 11L. In this way, the first person P1 can safely pass through the automatic door 100 without being dazzled by the image of the movable door 11L. In Fig. 7(H), the image control unit 81 moves the image outside the field of view S1 or line of sight S1 of the first person P1. In Fig. 7(I), the image control unit 81 displays an image of the opposite side of the movable door 11L in the field of view S1 or on the line of sight S1 of the first person P1. These image examples can prevent the field of view S1 of the first person P1 passing through the automatic door 100 from being obstructed by advertising images or the like, thereby improving safety while passing through.

[0062] In FIG. 7(J), the image control unit 81 displays on the movable door 11L as a display unit passage assistance information that assists the first person P1, who is an approaching person, to pass through the automatic door 100. Specifically, opening position information 811 indicating the position of the opening of the automatic door 100 and caution point information 812 indicating caution points such as the opening and closing part and mullions of the automatic door 100 are displayed on the movable door 11L as passage assistance information. When the movable door 11L and the other doors 12L, 11R, and 12R are used as displays for advertisement images, etc. as in FIG. 7(A), attention to the actual opening and closing operation of the automatic door 100 may be weakened. However, by displaying passage assistance information to the person approaching the automatic door 100 as in FIG. 7(J), attention to the opening and closing operation can be called, and safety during passage can be improved. Although the image examples of FIG. 7(B) to (J) have been described individually above, these image examples may be combined as appropriate. For example, the brightness of the image may be lowered as in FIG. 7(C) or the image may be reduced as in FIG. 7(D), and at the same time, traffic aid information as in FIG. 7(J) may be displayed.

[0063] FIG. 8 shows an example of an image display for a second person P2. In FIG. 8(A), images similar to those in FIG. 6 are displayed on each door 12L, 11L, 11R, and 12R. As described above, the second person P2 is looking at the advertisement image of the movable door 11R, and the center of the field of view or visual field is indicated by S2. FIG. 8(B) shows an example of an image of the movable door 11R displayed by the image control unit 81 for the second person P2 looking at the advertisement image. By displaying special discount information on the advertisement image that the second person P2 is looking at, the second person P2's motivation to purchase the product can be promoted. Note that such an image display is performed via the selection unit 83 described above. The selection unit 83 selects the second person P2 whose line of sight S2 has the movable door 11R (display device 37) based on the detection information acquired by the detection information acquisition unit 82, particularly the detection information of the image sensor 822. Then, the image control unit 81 causes the image of FIG. 8(B) directed at the second person P2, selected by the selection unit 83, to be displayed on the movable door 11R.

[0064] 9 shows an example in which the image control unit 81, having detected an abnormality in a person near the automatic door 100 based on the detection information acquired by the detection information acquisition unit 82, displays, on each of the doors 12L, 11L, 11R, and 12R, attention-calling information to alert the person about whom the abnormality has been detected. Since a third person P3 has entered the detection area 31B of the activation sensor 31 and is running toward the automatic door 100 at high speed and may collide with the movable doors 11L and 11R before they open, the image control unit 81 detects the abnormality and displays, on both movable doors 11L and 11R, attention-calling information 813 to urge the third person P3 to stop. Since the fourth person P4 is in contact with or close to the fixed door 12L within the detection area 31B of the activation sensor 31 and may collide with the movable door 11L when it opens, the image control unit 81 detects the abnormality and causes the fixed door 12L to display warning information 814 to warn the fourth person P4 not to stand in front of the fixed door 12L. Note that since there is no warning information to be displayed on the fixed door 12R, an advertising image or the like may be displayed as is.

[0065] FIG. 10 shows an example of an image that the image control unit 81 displays on each door 12L, 11L, 11R, and 12R in response to the operation of the movable doors 11L, 11R detected based on the detection information acquired by the detection information acquisition unit 82. In FIG. 10(A), an image similar to that in FIG. 6 is displayed on each door 12L, 11L, 11R, and 12R. FIG. 10(B) shows an example of an image during the opening operation of the movable doors 11L and 11R. In this example, the image in FIG. 10(A) appears to be displayed as is, but the image of the fixed door 12L in the part hidden by the movable door 11L at the position where the movable door 11L and the fixed door 12L overlap is not displayed, and the image of the fixed door 12R in the part hidden by the movable door 11R at the position where the movable door 11R and the fixed door 12R overlap is not displayed. By not displaying the image of the part that cannot be seen from the outside in this way, the power consumption of the display device 37 of the fixed doors 12L and 12R can be reduced.

[0066] Instead of Fig. 10(B), the size, direction, position, speed, etc. of the advertised goods in the image may be dynamically changed to match the screen of the fixed doors 12L, 12R which gradually becomes smaller as the movable doors 11L, 11R open as shown in Fig. 10(C). In this way, by dynamically changing the image according to the movement of the movable doors 11L, 11R, i.e., their position and speed, it is possible to attract the attention of people around the automatic door 100.

[0067] FIG. 10(D) shows a fully open state, in which the movable doors 11L and 11R overlap the fixed doors 12L and 12R, respectively. At this timing, the images of the doors 12L, 11L, 11R, and 12R are reset. In FIG. 10(E), images different from those in FIG. 10(A)-(C) gradually appear on the doors 12L, 11L, 11R, and 12R in response to the closing operation of the movable doors 11L and 11R. In the fixed doors 12L and 12R, the size, direction, position, speed, and the like of the advertised goods, etc. in the image change dynamically in accordance with the screen of the fixed doors 12L and 12R, which gradually becomes larger in response to the closing operation of the movable doors 11L and 11R, as in FIG. 10(C). In addition, in the movable doors 11L and 11R, the image control unit 81 performs image control such that the advertised goods, etc. in the image gradually approach from the rear to the front in accordance with the position and speed of the closing operation of the movable doors 11L and 11R.

[0068] FIG. 10(F) shows the fully closed state. As described above, an image different from that shown in FIG. 10(A), which shows the previous fully closed state, is displayed on each of the doors 12L, 11L, 11R, and 12R. In this way, by changing the image each time the movable doors 11L and 11R are opened and closed, it is possible to keep the interest of people around the automatic door 100. As another example of changing the image each time the movable doors 11L and 11R are opened and closed, the people and objects displayed on each of the doors 12L, 11L, 11R, and 12R may move slightly each time the movable doors 11L and 11R are opened and closed. In this case, the automatic door 100 functions like a flip book or a picture-story show in which people and objects move each time the doors are opened and closed.

[0069] In addition, when the image control unit 81 detects an exceptional operation different from the normal operation of the movable doors 11L and 11R based on the detection information acquired by the detection information acquisition unit 82, the image control unit 81 may display the explanatory information or the attention information on each of the doors 12L, 11L, 11R, 12R. For example, when the protective sensor 32 detects a passerby during the closing operation of the movable doors 11L and 11R, and a reversal operation in which the closing operation is switched to the opening operation occurs, the explanatory information or the attention information may be displayed on at least one of the doors 10. In addition, in a state in which the fourth person P4 is in contact with or close to the fixed door 12L as shown in FIG. 9, the opening operation of the movable doors 11L and 11R may be prohibited for safety reasons. If the explanatory information or the attention information is displayed on the fixed door 12R, for example, a person in the vicinity of the automatic door 100 can understand the reason why the movable doors 11L and 11R do not open.

[0070] The image control unit 81 may change the image displayed by the door 10 according to the congestion situation around the automatic door 100 estimated based on the detection information acquired by the detection information acquisition unit 82. For example, the image control unit 81 switches between displaying and hiding the image of the door 10 according to the estimated congestion situation. Specifically, when the area around the automatic door 100 is crowded, an advertisement image or the like is displayed on the door 10 so that many people can see it, whereas when the area around the automatic door 100 is not crowded, the image of the door 10 is hidden to reduce power consumption since few people will see the advertisement image or the like even if it is displayed. In addition, the image control unit 81 may change the brightness of the image of the door 10 according to the estimated congestion situation. For example, the brightness of the image of the door 10 is increased when the area is crowded, and the brightness of the image of the door 10 is decreased when the area is not crowded to reduce power consumption.
