Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventor of the present invention has obtained the following recognition regarding an automatic door device having a plurality of doors in one room.

[0005] For example, in a shared conference room, a shared toilet, etc., a single room may be provided with multiple entrances, and this room may be shared by different groups of users for each entrance. In the automatic door described in Patent Document 1, until the entrance confirmation means confirms the entrance to the washroom, the opening operation is not restricted, and during this time, the other door may also be opened. For example, when trying to open one door and enter, if the other door is also opened, it becomes unclear which user should be given priority, and there is a risk of causing confusion. In addition, this automatic door requires an entrance confirmation means and an exit confirmation means as essential components, resulting in a complicated configuration.

[0006] In view of such problems, the present invention has been made, and one of its purposes is to provide a technology for an automatic door device that can appropriately adjust the overlapping use of a room used through a plurality of doors with a simple configuration.

Means for Solving the Problems

[0007] To solve the above problems, an automatic door device according to an aspect of the present invention includes a plurality of drive units that open and close each of a plurality of doors provided in a private room, a plurality of outer instruction input units provided outside the private room to which an open or close instruction for a corresponding door among the plurality of doors is input, a plurality of inner instruction input units provided inside the private room to which an open or close instruction for a corresponding door among the plurality of doors is input, and a control unit that controls the drive units based on the instruction inputs of the plurality of outer instruction input units and the plurality of inner instruction input units. When an open instruction is input from any one of the plurality of outer instruction input units, the control unit invalidates the input of open instructions from the outer instruction input units other than the one outer instruction input unit and the inner instruction input units.

[0008] According to this aspect, when one outdoor operation unit is opened, the opening of other doors can be avoided.

[0009] Another aspect of the present invention is an automatic door device. This device includes a plurality of drive units that open and close each of a plurality of doors provided in a private room, a plurality of outer instruction input units provided outside the private room to which an open or close instruction for a corresponding door among the plurality of doors is input, a plurality of inner instruction input units provided inside the private room to which an open or close instruction for a corresponding door among the plurality of doors is input, a control unit that controls the drive units based on the instruction inputs from the plurality of outer instruction input units and the plurality of inner instruction input units, and a presence determination unit that determines whether there is a person in the private room. When a close instruction is input from any one of the plurality of inner instruction input units and the presence determination unit determines that there is a person, the control unit invalidates the instruction inputs from the other outer instruction input units and inner instruction input units.

[0010] Yet another aspect of the present invention is a control method for an automatic door device. This method includes a step of invalidating the instruction input from other outer instruction input units when an open instruction is output from one of the plurality of outer instruction input units for an automatic door device that opens and closes a plurality of doors based on instructions from a plurality of outer instruction input units and a plurality of inner instruction input units corresponding to the plurality of doors provided in a private room.

[0011] Still another aspect of the present invention is a control program for an automatic door device. This control program causes a computer to execute a step of invalidating the instruction input from other outer instruction input units when an open instruction is output from one of the plurality of outer instruction input units for an automatic door device that opens and closes a plurality of doors based on instructions from a plurality of outer instruction input units and a plurality of inner instruction input units corresponding to the plurality of doors provided in a private room.

[0012] Note that any combination of the above, or those obtained by mutually replacing the components and expressions of the present invention among a method, an apparatus, a program, a temporary or non-temporary storage medium recording the program, a system, etc. are also effective as aspects of the present invention.

Advantages of the Invention

[0013] According to the present invention, it is possible to provide a technology of an automatic door device that can appropriately adjust the use of a room used by a plurality of doors with a simple configuration.

[0017] In addition, for a plurality of the same components, "A", "B" are attached to the end of the reference signs for distinction, and these are omitted when they are collectively referred to.

[0018] [First Embodiment] Referring to FIGS. 1, 2, and 3, an automatic door device 100 according to a first embodiment of the present invention will be described. FIG. 1 is a plan view schematically showing a room 10 provided with the automatic door device 100. For convenience of explanation, as shown in the drawing, a horizontal direction is defined as the X direction, a horizontal direction orthogonal to the X direction is defined as the Y direction, and a vertical direction orthogonal to both of them is defined as the Z direction. The X direction may be referred to as the left - right direction, the Y direction may be referred to as the front - rear direction, and the Z direction may be referred to as the up - down direction. Such a direction notation does not limit the posture of the automatic door device 100, and the automatic door device 100 can be used in any posture.

[0019] The room 10 in this example can be provided in various facilities such as a station, a hotel, a department store, a hospital, a nursing home for the elderly, etc. There is no limitation on the type of the room 10, but the room 10 in this example is a toilet room used as a multi - functional toilet. The room 10 may be a private room.

[0020] The room 10 has an opening 102A provided in the front - side vertical wall 101 and an opening 102B provided in the rear - side vertical wall 101. The automatic door device 100 of the present embodiment opens and closes the opening 102A of the room 10 with a door 20A and opens and closes the opening 102B with a door 20B.

[0021] Room 10 is connected between two rooms, Room A and Room B, and can communicate with Room A through opening 102A and with Room B through opening 102B. That is, Room 10 is a shared toilet jointly used by Room A and Room B. Basically, a person entering Room 10 from one side of Room A and Room B is supposed to return to that side, and it is restricted to exit from the other side. Hereinafter, mainly the configuration for driving door 20A of opening 102A will be described, but this description is equally applicable to the configuration for driving door 20B of opening 102B.

[0022] Figure 2 is a front view showing Room 10 equipped with automatic door device 100. Figure 2 shows a partial break of vertical wall 101 of Room 10. Opening 102A in Figure 2 is provided closer to the right end side than the left and right center of vertical wall 101. Door 20A in this example is a sliding door that slides left and right.

[0023] Figure 3 is a block diagram showing automatic door device 100. Each block shown in Figure 3 can be realized in terms of hardware by elements and electronic circuits such as a computer's processor, CPU, memory, and mechanical devices, and in terms of software by a computer program or the like. Here, however, functional blocks realized by their cooperation are depicted. Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms by a combination of hardware and software.

[0024] As shown in FIG. 3, the automatic door device 100 includes a plurality of drive units 56A and 56B, a plurality of outer operation units 25, a plurality of inner operation units 27, and a control unit 52. The outer operation unit is an outer operation unit for operating from the outside of the room 10. The inner operation unit is an inner operation unit for operating from the inside of the room 10. The plurality of outer operation units 25 include an outer operation unit 25A provided on the opening 102A side (hereinafter sometimes simply referred to as the "A side") and an outer operation unit 25B provided on the opening 102B side (hereinafter sometimes simply referred to as the "B side"). The plurality of inner operation units 27 include an inner operation unit 27A provided on the opening 102A side and an inner operation unit 27B provided on the opening 102B side. When collectively referring to the plurality of outer operation units 25 and the plurality of inner operation units 27, they are simply referred to as operation units 25 and 27. The outer operation unit 25 exemplifies an outer instruction input unit, and the inner operation unit 27 exemplifies an inner instruction input unit.

[0025] The plurality of drive units 56A and 56B open and close the plurality of doors 20A and 20B provided in one room 10. The outer operation unit 25A and the inner operation unit 27A correspond to the door 20A and receive operations for opening and closing the door 20A. The outer operation unit 25B and the inner operation unit 27B correspond to the door 20B and receive operations for opening and closing the door 20B. The control unit 52 controls the drive units 56A and 56B based on the operations of the operation units 25 and 27.

[0026] A multifunctional toilet will be described. The multifunctional toilet is a toilet that is assumed to be used by wheelchair users, users with internal disabilities, etc. in addition to healthy people. A user with an internal disability is, for example, a user of a stoma such as an artificial anus or an artificial bladder. In the example of FIG. 1, in the room 10, a toilet 11, an ostomy 12, a washbasin 13, a bed 14, a baby chair 17, and a dressing table 18 are provided. The ostomy 12 is a washbasin for the user to wash the stoma. Also, handrails 15 are provided around the toilet 11 and the ostomy 12.

[0027] Also, in the example of FIG. 1, in room 10, a call operation unit 16 is provided near the toilet 11. The call operation unit 16 detects a user operation for a user who wants to request assistance from others due to poor physical condition or the like to notify the outside of this fact, and provides the detection result to the control unit 52 as a call signal. The call operation unit 16 of the present embodiment provides the control unit 52 with a call signal composed of a detection state in which a user operation is detected and a non-detection state in which no detection is made as a detection result. The call signal is turned on in the detection state and turned off in the non-detection state. The call operation unit 16 in this example is a push button switch that turns on the call signal when pressed and turns off the call signal when released. The call operation unit 16 may be referred to as a call switch. The control unit 52 executes a predetermined emergency operation when the call signal of the call operation unit 16 is on. This emergency operation includes notification of the detection result to the administrator of room 10, display of the detection result on the outdoor notification unit 46, and release of the movement restriction of the door 20 by the door lock unit 48. The call operation unit 16 also functions as an emergency button.

[0028] Also, in room 10, an indoor notification unit 30 and an extension operation unit 31 are provided near the cohabitant 12. The indoor notification unit 30 is a device that notifies a user of a predetermined matter from the administrator of room 10 or the control unit 52. The indoor notification unit 30 can notify a predetermined matter, for example, through the sound of a speaker or a display such as a liquid crystal display. When a usage restriction time (for example, 30 minutes) is set for room 10, the control unit 52 executes a predetermined indoor notification operation through the indoor notification unit 30 according to the elapsed time since the user entered the room. This indoor notification operation includes notification of the remaining time until the usage restriction time, notification of exceeding the usage restriction time, and release of the movement restriction of the door 20 by the door lock unit 48. Also, when the usage restriction time is exceeded, the control unit 52 notifies the outdoor notification unit 46 and the administrator of room 10 that the usage restriction time has been exceeded.

[0029] The extension operation unit 31 detects a user operation for extending the usage restriction time and provides the detection result to the control unit 52 as an extension signal. The extension operation unit 31 of the present embodiment provides the control unit 52 with an extension signal composed of a detection state in which a user operation is detected and a non-detection state in which no user operation is detected as the detection result. The extension signal is turned on in the detection state and turned off in the non-detection state. The extension operation unit 31 in this example is a push button switch that turns on the extension signal when pressed and turns off the extension signal when released. Hereinafter, the extension operation unit 31 may be referred to as an extension switch. When the extension signal of the extension operation unit 31 is on, the control unit 52 extends the usage restriction time by a predetermined time (for example, 10 minutes).

[0030] The drive unit 56 drives the door 20 to open and close the opening 102. The door 20 is a moving body that is horizontally slidably provided on a movement path 22 extending from the fully closed position to the fully open position. The movement path 22 is the movement locus of the door 20 projected on the floor surface.

[0031] The operation units 25 and 27 receive a user operation for opening the door (hereinafter referred to as an "open operation") and a user operation for closing the door (hereinafter referred to as a "close operation"). In particular, the outer operation units 25A and 25B and the inner operation units 27A and 27B each have an open operation unit that receives an open operation and a close operation unit that receives a close operation in each operation unit.

[0032] The operation units 25 and 27 provide an open door activation signal to the control unit 52 based on the open operation and a close door activation signal to the control unit 52 based on the close operation. When collectively referring to the open door activation signal and the close door activation signal, it may be referred to as an "activation signal". Based on the activation signal of the operation units 25 and 27, the control unit 52 controls the drive unit 56 to cause the door 20 to perform an opening operation (hereinafter referred to as an "opening operation") or a closing operation (hereinafter referred to as a "closing operation").

[0033] In this embodiment, the external operation unit 25 is an operation unit that can be operated from the outside of the room 10, and the internal operation unit 27 is an operation unit that can be operated from the inside of the room 10. In the example of FIG. 1, the external operation unit 25 is provided on the outside of the standing wall 101, and the internal operation unit 27 is provided on the inside of the standing wall 101. The operation units 25 and 27 may be provided on the door 20.

[0034] As the operation units 25 and 27, devices based on various principles capable of inputting user operations can be adopted. The operation units 25 and 27 of this embodiment are push-button switches that turn on the activation signal when pressed and turn off the activation signal when released.

[0035] The drive unit 56 slides the door 20 based on the control of the control unit 52. The drive unit 56 may be referred to as a door engine. For example, the drive unit 56 can be composed of a loop-shaped belt (not shown) to which the door 20 is connected and a drive motor 562 that drives the belt. The rotation of the drive motor 562 is controlled by the control unit 52 via the drive circuit 561. The drive unit 56 may be provided in the blind of the standing wall 101.

[0036] In this embodiment, the drive unit 56 includes a resistance detection unit 36 and a position detection unit 38. The resistance detection unit 36 and the position detection unit 38 provide the detection results to the control unit 52. The resistance detection unit 36 detects the moving resistance of the door 20 during movement. The moving resistance of the door 20 is a resistance force in the direction opposite to the moving direction received by the door 20 during movement, and may be referred to as running resistance or sliding resistance. The moving resistance becomes larger than normal when there is something in contact with the moving body. As an example, the resistance detection unit 36 is a current sensor that transmits the result of detecting the drive current of the drive motor 562 to the control unit 52. The control unit 52 can specify the moving resistance based on the detection result of the resistance detection unit 36.

[0037] The position detection unit 38 detects the position of the door 20 from the fully closed position to the fully open position. As an example, the position detection unit 38 is an incremental encoder that transmits a position signal, which is a pulse signal of the number of pulses proportional to the rotation angle of the drive motor 562, to the control unit 52. The control unit 52 moves the door 20 to the fully closed position when the automatic door device 100 is activated, uses the fully closed position as a reference position, and can identify the position of the door 20 by counting the number of pulses of the position signal from the position detection unit 38.

[0038] The automatic door device 100 of the present embodiment includes a warning output unit 44 that issues a warning to the user based on the control of the control unit 52. The warning output unit 44 in this example has a sound output unit 441 that emits a warning sound and a light output unit 442 that emits a warning light based on the control of the control unit 52. The sound output unit 441 can be configured to include, for example, a speaker. The light output unit 442 can be configured to include a light-emitting element such as an LED. The warning output unit 44 may be provided on the standing wall 101 as shown in the figure.

[0039] In the present embodiment, the automatic door device 100 includes an opening detection unit 32 that can detect an object existing in the movement path of the door 20 at the opened opening 102. The opening detection unit 32 may be referred to as an auxiliary sensor. The opening detection unit 32 in this example provides an opening detection signal, which consists of a detection state in which an object is detected and a non-detection state in which no object is detected, to the control unit 52 as a detection result. The opening detection signal turns on in the detection state and turns off in the non-detection state. The control unit 52 restricts the closing operation of the door 20 when the opening detection unit 32 is in the detection state. Examples of the object to be detected by the opening detection unit 32 include the user's body and luggage. As an example, the opening detection unit 32 can be configured to include a set of a projector and a light receiver provided at positions on the standing wall 101 that are separated left and right across the opening 102.

[0040] In the room 10 of the present embodiment, a presence determination unit 28 for determining whether a person is in the room 10 is provided. The operation principle of the presence determination unit 28 is not particularly limited. However, the presence determination unit 28 of the present embodiment is a human sensor configured to include a pyroelectric element capable of detecting changes in infrared rays emitted by a person. The presence determination unit 28 in this example provides a presence determination signal to the control unit 52, which consists of a presence state determined as a person being present and an absence state determined as no person being present, according to the signal of the pyroelectric element. The presence determination signal is turned on in the presence state and turned off in the absence state.

[0041] In the room 10 of the present embodiment, an outdoor notification unit 46 for notifying the outside of the indoor state such as the presence state and abnormal state of the room 10 is provided. The outdoor notification unit 46 in FIG. 2 is, as an example, a display for displaying the character "In use" based on the control of the control unit 52. The outdoor notification unit 46 may be provided on the blind part of the standing wall 101 as shown in the figure. For example, when the presence determination unit 28 determines that a person is in the room 10, the control unit 52 causes the outdoor notification unit 46 to display "In use", and when it determines that no person is present, stops this display.

[0042] In the room 10 of the present embodiment, a door lock unit 48 for restricting the movement of the closed door 20 is provided based on the control of the control unit 52. The door lock unit 48 may be, for example, an electric lock or the like that locks the door 20 by electromagnetic force to mechanically restrict the movement of the door 20, or may invalidate the door opening activation signals of the operation units 25 and 27 to controllably restrict the opening operation by the operation of the operation units 25 and 27, or may use a combination of these. For example, when the room 10 is in use, the control unit 52 can turn on the door lock unit 48 to restrict the movement of the door 20.

[0043] Next, the control unit 52 will be described. As shown in FIG. 3, the control unit 52 of the present embodiment includes an information acquisition unit 521, an information output unit 522, a door operation control unit 523, a storage unit 526, a time determination unit 527, a time management unit 528, and a transmission unit 529, and functions as an information processing unit.

[0044] The information acquisition unit 521 functions as an input port that acquires output signals from the external operation units 25A and 25B, the internal operation units 27A and 27B, the detection units 32A and 32B, the occupancy determination unit 28, the call operation unit 16, the extension operation unit 31, the resistance detection unit 36, and the position detection unit 38.

[0045] The information output unit 522 outputs control signals for controlling the sound output unit 441, the light output unit 442, the indoor notification unit 30, the outdoor notification unit 46, and the door lock unit 48. The information output unit 522 functions as an output port. The door operation control unit 523 outputs a control signal to the drive circuit 561 of the drive unit 56 to control the operation of the door 20. The door operation control unit 523 includes a door operation control unit 523A that drives the drive unit 56A and a door operation control unit 523B that drives the drive unit 56B.

[0046] The storage unit 526 temporarily stores information regarding the output signals acquired by the information acquisition unit 521. A control program P100 described later is stored in the storage unit 526. The time management unit 528 functions as a time counter that counts the elapsed time after the user enters the room. The time determination unit 527 determines whether the elapsed time counted by the time management unit 528 exceeds the usage limit time. The transmission unit 529 transmits predetermined information to be output to the outside, such as the administrator of the room 10. This predetermined information includes that the call operation unit 16 has been operated and that the usage limit time has been exceeded.

[0047] The operation of the automatic door device 100 configured as described above will be described.

[0048] (First Operation) Referring to FIG. 4, a first operation S110, which is an operation example of the automatic door device 100, will be described. FIG. 4 is a flowchart showing the first operation S110. The first operation S110 is an example of an operation when entering through an arbitrary opening door and exiting through the same opening. Here, the opening 102A will be described as an arbitrary opening, the opening 102B as another opening, and the door 20B as another door. Hereinafter, in the description of the operation, the external operation unit 25A will be referred to as the external operation unit A, the internal operation unit 27A as the internal operation unit A, the external operation unit 25B as the external operation unit B, and the internal operation unit 27B as the internal operation unit B.

[0049] When entering room 10, the user opens the external operation unit A (step S111).

[0050] When the external operation unit A is opened, the door opening activation signal turns on, and the control unit 52 disables the opening operation of the other external operation unit (external operation unit B) (step S112). Here, "disabling the operation of the operation unit" means that even if the operation unit is operated, the control unit 52 does not execute the operation based on that operation. For example, when the opening operation is disabled, the opening operation is not executed even if there is such an opening operation. Also, when the closing operation is disabled, the closing operation is not executed even if there is such a closing operation. That is, the door 20A corresponding to the previously operated external operation unit A opens, and even if the external operation unit B is operated later, the door 20B does not open. This state continues until the invalidation of the operation is released.

[0051] After executing step S112, the control unit 52 controls the drive unit 56A to open the door 20A (step S113). By the opening operation, the door 20A moves to the fully open position and stops.

[0052] When the door 20A is fully open, the control unit 52 enables the closing operation of the internal operation unit A corresponding to the external operation unit A, and disables the operations (opening operation and closing operation) of the other operation units (internal operation unit B) (step S114). In this case, by disabling the operation of the internal operation unit B, it is possible to prevent a person who has entered through the door 20A from passing through when exiting through the door 20B. Here, "enabling the operation of the operation unit" means that when the operation unit is operated, the control unit 52 executes the operation based on that operation. If the operation of the operation unit was originally invalid, it is enabled, and if the operation of the operation unit was originally valid, that state is continued.

[0053] After entering room 10, the user closes the valid internal operation unit A (step S115).

[0054] When the internal operation unit A is closed, the door closing start signal is turned on, and the control unit 52 controls the drive unit 56A to close the door 20A (step S116). By this closing operation, the door 20A moves to the fully closed position and stops. In this state, the user uses the facilities in the room 10.

[0055] When the user exits from the room 10, the user operates the internal operation unit A to open it (step S117). At this time, since the opening operation of the internal operation unit B is invalid, the user cannot open the door 20B.

[0056] When the internal operation unit A is opened, the door opening start signal is turned on, and the control unit 52 controls the drive unit 56A to open the door 20A (step S118). By this opening operation, the door 20 moves to the fully open position and stops.

[0057] After the user exits from the room 10, the user operates the external operation unit A to close it (step S119).

[0058] When the external operation unit A is closed, the door closing start signal is turned on, and the control unit 52 controls the drive unit 56A to close the door 20A (step S120). By this closing operation, the door 20A moves to the fully closed position and stops.

[0059] After the door 20A is fully closed, it is determined whether there is a person in the room 10 (step S121). In this step, the control unit 52 obtains the determination result of the occupancy determination unit 28.

[0060] When the occupancy determination unit 28 determines that there is a person in the room 10 (Y in step S121), the control unit 52 returns the process to the start of step S121 and repeats step S121.

[0061] When the in-room determination unit 28 determines that there is no person in the room 10 (N in step S121), the control unit 52 releases the invalidation of operations for the other operation units (external operation unit B) that have been invalidated (step S122). Here, "releasing the invalidation of operations" means that the control unit 52 returns to the state before invalidation and, when there is such an operation, executes the original operation based on that operation. For example, when releasing the invalidation of the open operation, the control unit 52 executes the open operation based on this operation if there is an open operation.

[0062] When step S122 is executed, operation S110 ends. Each of the above steps is an example, and various modifications are possible. When entering and exiting through the opening 102B, operation S110 can be similarly applied by designating the opening 102B as an arbitrary opening, the opening 102A as another opening, and swapping the endings of each reference sign. Operation S110 may be executed alone or in combination with operations S210 to S610 described later.

[0063] (Second operation) Referring to FIG. 5, a second operation S210, which is another operation example of the automatic door device 100, will be described. FIG. 5 is a flowchart showing the second operation S210. The second operation S210 is an example of an operation when entering through a door of an arbitrary opening and exiting through the same opening. Here, the opening 102A will be described as an arbitrary opening, the opening 102B as another opening, and the door 20B as another door.

[0064] When entering the room 10, the user operates the external operation unit A to open it (step S211).

[0065] When the external operation unit A is operated to open, the door opening activation signal turns on, and the control unit 52 invalidates the open operations of the other external operation units (external operation unit B) (step S212).

[0066] After executing step S212, the control unit 52 controls the drive unit 56A to open the door 20A (step S213). By the opening operation, the door 20A moves to the fully open position and stops.

[0067] After entering room 10, the user closes the inner operation unit A (step S214).

[0068] When the inner operation unit A is closed, the door closing activation signal turns on, and the control unit 52 controls the drive unit 56A to close the door 20A (step S215). By the closing operation, the door 20A moves to the fully closed position and stops. In this state, the user uses the facilities in room 10.

[0069] When the door 20A is fully closed, it is determined whether there is a person in room 10 (step S216). In this step, the control unit 52 obtains the determination result of the occupancy determination unit 28.

[0070] When the occupancy determination unit 28 determines that there is no person in room 10 (N in step S216), the control unit 52 advances the process to the beginning of step S223.

[0071] When the occupancy determination unit 28 determines that there is a person in room 10 (Y in step S216), the control unit 52 enables the closing operation of the inner operation unit A corresponding to the outer operation unit A, and disables the operations (opening operation and closing operation) of other operation units (inner operation unit B) (step S217). In this case, by disabling the operation of the inner operation unit B, it is possible to prevent a person who entered through the door 20A from passing through and exiting through the door 20B. In this state, the opening operation of the outer operation unit B disabled in step S212, and the opening operation and closing operation of the inner operation unit B are disabled.

[0072] When exiting room 10, the user opens the inner operation unit A (step S218). At this time, since the opening operation of the inner operation unit B is disabled, the user cannot open the door 20B.

[0073] When the inner operation unit A is opened, the door opening activation signal turns on, and the control unit 52 controls the drive unit 56A to open the door 20A (step S219). By the opening operation, the door 20A moves to the fully open position and stops.

[0074] After exiting Room 10, the user closes the external operation unit A (step S220).

[0075] When the external operation unit A is closed, the door closing activation signal turns on, and the control unit 52 controls the drive unit 56A to close the door 20A (step S221). By the closing operation, the door 20A moves to the fully closed position and stops.

[0076] When the door 20A is fully closed, it is determined whether there is a person in Room 10 (step S222). In this step, the control unit 52 acquires the determination result of the occupancy determination unit 28.

[0077] When the occupancy determination unit 28 determines that there is a person in Room 10 (Y in step S222), the control unit 52 returns the process to the beginning of step S222 and repeats step S222.

[0078] When the occupancy determination unit 28 determines that there is no person in Room 10 (N in step S222), the control unit 52 determines whether all the doors (doors 20A, 20B) are fully closed (step S223).

[0079] When it is determined that the doors are not fully closed (N in step S223), the control unit 52 returns the process to the beginning of step S223 and repeats step S223.

[0080] When it is determined that the doors are fully closed (Y in step S223), the control unit 52 releases the invalidation of the operations of all the operation units including the other operation unit (external operation unit B) that was invalidated (step S224).

[0081] When step S224 is executed, operation S210 ends. Each of the above steps is an example, and various modifications are possible. When entering and exiting through the opening 102B, operation S210 can be similarly applied by designating the opening 102B as an arbitrary opening, the opening 102A as another opening, and swapping the endings of each symbol. Operation S210 may be executed alone or in combination with operation S110.

[0082] (Third operation) Referring to FIG. 6, a third operation S310, which is another operation example of the automatic door device 100, will be described. FIG. 6 is a flowchart showing the third operation S310. The third operation S310 is an example of an operation when opening a door of an arbitrary opening. Here, the opening 102A will be described as an arbitrary opening, the opening 102B as another opening, and the door 20B as another door.

[0083] When entering the room 10, the user opens the outer operation unit A (step S311).

[0084] After executing step S311, it is determined whether there is a person in the room 10 (step S312). In this step, the control unit 52 acquires the determination result of the occupancy determination unit 28.

[0085] When the occupancy determination unit 28 determines that there is a person in the room 10 (Y in step S312), the control unit 52 determines whether all the doors (doors 20A, 20B) are fully closed (step S313).

[0086] When not all the doors are fully closed (N in step S313), the control unit 52 ends the third operation S310.

[0087] When all the doors are fully closed (Y in step S313), the control unit 52 determines whether the operated operation unit is on the inner side (indoor side) (step S314).

[0088] When the operated operation unit is not on the inner side (N in step S314), the control unit 52 ends the third operation S310.

[0089] When the operated operation unit is on the inner side (Y in step S314), the control unit 52 determines whether the operated operation unit (outer operation unit A) is on the side where the user enters the room (step S315).

[0090] When the operated operation unit is not on the side where the user enters the room (N in step S315), the control unit 52 ends the third operation S310.

[0091] When the operated operation unit is on the side where the user entered the room (Y in step S315), the control unit 52 opens the door 20A corresponding to the operated operation unit (outer operation unit A) (step S316).

[0092] In step S312, when the occupancy determination unit 28 determines that there is no person in the room 10 (N in step S312), the control unit 52 determines whether all the doors (doors 20A, 20B) are fully closed (step S317).

[0093] When not all the doors are fully closed (N in step S317), the control unit 52 ends the third operation S310.

[0094] When all the doors are fully closed (Y in step S317), the control unit 52 advances the process to the beginning of step S316 and executes step S316.

[0095] When step S316 is executed, the operation S310 ends. Each of the above steps is an example, and various modifications are possible. When entering and exiting from the opening 102B, the operation S310 can be similarly applied by taking the opening 102B as an arbitrary opening, the opening 102A as another opening, and swapping the endings of each symbol. The operation S310 may be executed alone or in combination with the operations S110 to S210.

[0096] (Fourth operation) Referring to FIG. 7, a fourth operation S410, which is another operation example of the automatic door device 100, will be described. FIG. 7 is a flowchart showing the fourth operation S410. The fourth operation S410 is an example of an operation when a predetermined process is executed when the room 10 becomes in a use state. Here, the opening 102A will be described as an arbitrary opening, the opening 102B as another opening, and the door 20B as another door. Also, the opening 102A may be referred to as the frontage on the A side, the door 20A as the door on the A side, the opening 102B as the frontage on the B side, and the door 20B as the door on the B side.

[0097] When the fourth operation S410 starts, the control unit 52 determines whether all doors (doors 20A and 20B) are fully closed and whether there is no person in the room 10 (step S411).

[0098] When the determination condition in step S411 is not satisfied (N in step S411), the control unit 52 returns the process to the beginning of step S411 and repeats step S411.

[0099] When all doors are fully closed and there is no person in the room 10 (Y in step S411), and when the user opens the outer operation unit A of an arbitrary door (in this case, door 20A) (step S412), the control unit 52 controls the drive unit 56A to open the door 20A (step S413). By the opening operation, the door 20A moves to the fully open position and stops.

[0100] After entering the room 10, if any operation unit is closed (step S414), the control unit 52 determines whether the closed operation unit is an inner operation unit (inner operation units A and B) (step S415).

[0101] When the closed operation unit is not an inner operation unit (N in step S415), the control unit 52 determines whether the operated operation unit is the same bay as the bay where the entry was made (step S419). That is, in this example, when the closed operation unit is an outer operation unit, the control unit 52 determines whether the operation unit is on the A side.

[0102] When the operated operation unit is not the same bay (N in step S419), the control unit 52 returns the process to the beginning of step S414 and repeats steps S414 to S419. That is, in this example, when the operated operation unit is not on the A side (is on the B side), the control unit 52 returns the process to step S414.

[0103] When the operated operation unit is of the same bay width (Y in step S419), the control unit 52 closes the door of the bay width on the operated side (step S420). That is, in this example, the control unit 52 controls the drive unit 56A to close the door 20A on the A side that was opened in step S412. After executing step S420, the control unit 52 returns the process to the start of step S411. By this operation, the user can exit from the bay width on the side where the user entered the room, but cannot exit from another bay width, preventing passage through.

[0104] When the closed operation unit is the internal operation unit (Y in step S415), the control unit 52 controls the drive unit 56A to close the door corresponding to the closed operation unit (in this case, the door 20A) (step S416). By the closing operation, the door 20A moves to the fully closed position and stops. In this state, the user uses the facilities in the room 10.

[0105] After executing step S416, the control unit 52 controls the outdoor notification unit 46 to display that the room 10 is in use (step S417).

[0106] After executing step S416, the control unit 52 executes a predetermined process (step S418). There is no limitation to this process. For example, when the control unit 52 is separated into a sub-control unit 52A (not shown) of the door 20A and a sub-control unit 52B (not shown) of the door 20B and are arranged separately, this predetermined process may be a process of transmitting predetermined information from one of these sub-control units 52A, 52B to the other. For example, the sub-control unit 52A is installed at the opening 102A, and the sub-control unit 52B is installed at the opening 102B. For example, this process may be a process of transmitting from the sub-control unit 52A to the sub-control unit 52B that the room 10 is in use and that the user entered the room 10 from the opening 102A when the user enters the room 10 from the opening 102A and the door 20A is closed at the internal operation unit A.

[0107] When step S418 is executed, operation S410 ends. Each of the above steps is an example, and various modifications are possible. When entering and exiting through opening 102B, operation S410 can be similarly applied by using opening 102B as an arbitrary opening, opening 102A as another opening, and swapping the endings of each reference sign. Operation S410 may be executed alone or in combination with operations S110 to S310.

[0108] (Fifth Operation) Referring to FIG. 8, a fifth operation S510, which is another operation example of the automatic door device 100, will be described. FIG. 8 is a flowchart showing the fifth operation S510. The fifth operation S510 is an operation for executing a predetermined emergency process when a user in the room 10 wants to request assistance from others due to poor physical condition or the like (for example, in an emergency).

[0109] When the user operates the call operation unit 16 in the state where the fifth operation S510 has started (step S511), the control unit 52 activates the outdoor notification unit 46 (step S512). In this step, the control unit 52 controls the outdoor notification unit 46 to display that it is an emergency situation.

[0110] After executing step S512, the control unit 52 executes a predetermined emergency process (step S513). As an example, the emergency process in step S513 may include enabling the opening operation of the operation units of all openings, or opening the doors 20 of all openings (moving the doors 20 to the fully open position).

[0111] When step S513 is executed, operation S510 ends. Each of the above steps is an example, and various modifications are possible. Operation S510 may be executed alone or in combination with operations S110 to S410.

[0112] (Sixth Operation) Referring to FIG. 9, a sixth operation S610, which is another operation example of the automatic door device 100, will be described. FIG. 9 is a flowchart showing the sixth operation S610. The sixth operation S610 is an operation for executing predetermined abnormal-time processing when a master key switch (not shown) is operated. The master key switch is a switch for an administrator or the like of the room 10 to enter the room 10 in case of an abnormality, and can be operated by using a master key held by the administrator or the like.

[0113] In a state where the sixth operation S610 has been started, if an administrator or the like who senses some abnormality operates the master key switch using the master key (step S611), the control unit 52 executes predetermined abnormal-time processing (step S612). As an example, the abnormal-time processing in step S612 may include enabling the opening operation of the operation units of all openings, or opening the doors 20 of all openings (moving the doors 20 to the fully open position).

[0114] When step S612 is executed, the operation S610 ends. Each of the above steps is an example, and various modifications are possible. The operation S610 may be executed alone, or may be executed in combination with the operations S110 to S510.

[0115] The features of the automatic door device 100 of the present embodiment configured as described above will be described.

[0116] The automatic door device 100 of this embodiment includes a plurality of drive units 56A and 56B that open and close each of a plurality of doors 20A and 20B provided in a private room (room 10), a plurality of outer instruction input units (outer operation units 25A and 25B) provided outside the private room to which an open or close instruction for a corresponding door among the plurality of doors 20A and 20B is input, a plurality of inner instruction input units (inner operation units 27A and 27B) provided inside the private room to which an open or close instruction for a corresponding door among the plurality of doors 20A and 20B is input, and a control unit 52 that controls the drive units based on instruction inputs from the plurality of outer instruction input units and the plurality of inner instruction input units. When an open instruction is input from any one of the plurality of outer instruction input units, the control unit 52 invalidates the input of open instructions from the outer instruction input units other than the one outer instruction input unit and the inner instruction input units.

[0117] According to this configuration, with a simple configuration, the overlapping use of rooms utilized by a plurality of doors can be appropriately adjusted.

[0118] This embodiment includes an occupancy determination unit 28 that determines whether there is a person in the room 10. When the occupancy determination unit 28 determines that there is no person in the state where the door 20 opened by the open operation of one outer operation unit 25A is fully closed, the control unit 52 cancels the invalidation of the open operation of the other outer operation unit 25B. In this case, when the invalidation of the open operation of the outer operation unit 25B is canceled, both doors 20A and 20B become usable.

[0119] In this embodiment, when the door 20 is opened by the open operation of one outer operation unit 25A, the control unit 52 enables the close operation of one inner operation unit 27A corresponding to the one outer operation unit 25A among the plurality of inner operation units 27A and 27B, and invalidates the operation of the other inner operation unit 27B. In this case, it is possible to prevent a person who has entered through one opening from passing through and exiting through the other opening.

[0120] This embodiment includes a plurality of drive units 56 for opening and closing a plurality of doors 20A and 20B provided in one room 10, a plurality of external operation units 25A and 25B and a plurality of internal operation units 27A and 27B corresponding to the plurality of doors 20, a control unit 52 for controlling the drive units 56 based on the operations of the plurality of operation units 25 and 27, and a presence determination unit 28 for determining whether there is a person in the room 10. When the control unit 52 determines that there is a person in the room 10 after one of the internal operation units 27A among the plurality of internal operation units 27A and 27B is closed, the control unit 52 invalidates the open operations of the other operation units 25A, 25B, and 27B among the plurality of operation units 25 and 27, excluding one internal operation unit 27A.

[0121] According to this configuration, it is possible to prevent an opening operation from the outside when there is a person in the room 10, and to prevent a person who has entered through one opening from passing through and exiting through another opening.

[0122] In this embodiment, when the presence determination unit 28 determines that there is no person in the room, and when all of the plurality of doors 20 are closed, the control unit 52 releases the invalidation of the open operations of the other operation units 25A, 25B, and 27B. In this case, when the invalidation of the open operations of the other operation units 25A, 25B, and 27B is released, both doors 20A and 20B become usable.

[0123] The above is the description of the first embodiment.

[0124] Hereinafter, the second and third embodiments of the present invention will be described. In the drawings and descriptions of the second and third embodiments, the same or equivalent components and members as those in the first embodiment are denoted by the same reference numerals. Descriptions overlapping with those of the first embodiment are omitted as appropriate, and the configurations different from those of the first embodiment will be mainly described.

[0125] [Second Embodiment] The second embodiment of the present invention is a control method for an automatic door device. This control method is for an automatic door device that opens and closes a plurality of doors based on instructions from a plurality of outer instruction input units and a plurality of inner instruction input units corresponding to the plurality of doors provided in a private room. Among the plurality of outer instruction input units, when an open instruction is output from one outer instruction input unit, it includes the step of invalidating instruction inputs from other outer instruction input units. As an example, this control method is for an automatic door device 100 that opens and closes a plurality of doors 20 based on operations of a plurality of outer operation units 25 and a plurality of inner operation units 27 corresponding to the plurality of doors 20 provided in a room 10. Among the plurality of outer operation units 25A, 25B, when one outer operation unit 25A is operated to open, it includes step S112 of invalidating the open operation of the other outer operation unit 25B.
