Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventor conceived of using a non-contact sensor for opening and closing control of an automatic door installed in a public toilet or the like. In a public toilet, it is common to provide push buttons or switches for opening and closing inside and outside the toilet cubicle or toilet room, and the opening and closing control of the door is performed according to the user's pressing operation or contact operation. As a result of the inventor's independent study of providing a non-contact type opening and closing switch in addition to such a contact type opening and closing switch, the present invention has been completed.

[0005] The present invention has been made in view of such circumstances, and an object thereof is to provide an automatic door device or the like that can realize appropriate control when a non-contact switch is provided.

Means for Solving the Problems

[0006] In order to solve the above problems, an automatic door device according to an aspect of the present invention includes a door control unit that controls opening and closing of a door provided at an opening of a private room based on an opening / closing instruction signal, a contact-type contact switch, a non-contact-type non-contact switch, and a switch control unit that outputs an opening / closing instruction signal in response to a contact operation of the contact switch by a user and a non-contact operation of the non-contact switch by the user. At least one of the door control unit and the switch control unit restricts control based on the other type of switch after one type of switch among the contact switch and the non-contact switch is operated.

[0007] In this aspect, since control based on the other type of switch is restricted when one type of switch among the contact switch and the non-contact switch is operated, it is possible to realize control suitable for a case where a user wants to preferentially use one type of switch.

[0008] Another aspect of the present invention is also an automatic door device. This device includes a door control unit that controls opening and closing of a door provided at an opening of a private room based on an opening / closing instruction signal, a contact-type contact switch, a non-contact-type non-contact switch, a switch control unit that outputs an opening / closing instruction signal in response to a contact operation of the contact switch by a user and a non-contact operation of the non-contact switch by the user, and a contact detection unit that detects contact with a braille display provided near the contact switch. At least one of the door control unit and the switch control unit restricts control based on the non-contact switch after the contact detection unit enters a detection state.

[0009] In this aspect, since control based on the non-contact switch is restricted when contact with the braille display provided near the contact switch is detected, it is possible to realize control suitable for a case where a user with a visual impairment or the like wants to preferentially use the contact switch.

[0010] Yet another aspect of the present invention is a switch device for an automatic door device. This device is a switch device for an automatic door device that includes a contact switch for opening and closing a door provided at an opening of a private room, and includes a non-contact switch and a switch control unit that outputs an opening / closing instruction signal for opening and closing the door in response to a non-contact operation of the non-contact switch by a user. When the door is under open control or close control in response to an operation of the contact switch, the switch control unit restricts subsequent control based on the non-contact switch.

[0011] Yet another aspect of the present invention is a control method for an automatic door device. This method is a control method for an automatic door device that is opened and closed based on an opening / closing instruction signal output from a contact switch or a non-contact switch, and includes a step of acquiring an opening / closing instruction signal from either the contact switch or the non-contact switch, and a step of restricting control based on the other type of switch when the opening / closing instruction signal from one of the switches is acquired.

[0012] Yet another aspect of the present invention is a switch device for an automatic door device. This device is a switch device for an automatic door device that includes a contact switch for opening and closing a door provided at an opening of a private room, and includes a non-contact switch, a switch control unit that outputs an opening / closing instruction signal for opening and closing the door in response to a non-contact operation of the non-contact switch by a user, and a contact detection unit that detects contact with a Braille display provided near the contact switch. When the contact detection unit enters a detection state, the switch control unit restricts subsequent control based on the non-contact switch.

[0013] Yet another aspect of the present invention is a control method for an automatic door device. This method is a control method for an automatic door device that is opened and closed based on an opening / closing instruction signal output from a contact switch or a non-contact switch, and includes a step of detecting contact with a Braille display provided near the contact switch, and a step of restricting control based on the non-contact switch after the contact with the Braille display is detected.

[0014] In addition, any combination of the above components, as well as those obtained by converting the expression of the present invention among methods, apparatuses, systems, recording media, computer programs, etc., are also effective as aspects of the present invention.

Advantages of the Invention

[0015] According to the present invention, appropriate control in an automatic door device provided with a non-contact switch can be realized.

Embodiments for Carrying Out the Invention

[0017] FIG. 1 is a plan view schematically showing a toilet room 10 as a room where an automatic door device 100 is installed. FIG. 2 is a front view showing the toilet room 10 where the automatic door device 100 is installed. In FIG. 2, a part of the front wall 101 of the toilet room 10 is shown broken. Hereinafter, the horizontal direction that coincides with the opening and closing direction of the door 20 is referred to as the X direction, the horizontal direction perpendicular to the X direction that substantially coincides with the entrance and exit direction of the door 20 is referred to as the Y direction, and the vertical direction orthogonal to the X direction and the Y direction is referred to as the Z direction. Also, the X direction may be referred to as the left-right direction, the Y direction may be referred to as the front-back direction, and the Z direction may be referred to as the up-down direction. Such a direction notation does not limit the installation posture of the automatic door device 100, and the automatic door device 100 can be installed in any posture. The toilet room 10 is a private room provided with a toilet 11. Note that the automatic door device 100 of the present embodiment can be installed not only in the toilet room 10 but also to open and close the opening of any room.

[0018] The automatic door device 100 is a device that controls the opening and closing of a door 20 provided in an opening such as a wall that partitions a space. Specifically, an opening 102 provided in the front wall 101 of the toilet room 10 is opened and closed by a door 20 as a sliding door that slides in the left-right direction. The opening 102 in FIG. 2 is provided to the right of the left-right center of the front wall 101. The toilet room 10 constitutes a public toilet provided in various facilities such as commercial facilities such as stations and stores, hotels, and hospitals.

[0019] The public toilet illustrated in FIGS. 1 and 2 is a barrier-free toilet in which various facilities and appliances available to a variety of users are provided in the toilet cubicle 10. As users of the barrier-free toilet, in addition to healthy people, wheelchair users, internal disabled people such as ostomates who have had a stoma such as an artificial anus or an artificial bladder, elderly people, and those with children are assumed. As shown in FIG. 1, in the toilet cubicle 10, a toilet 11, ostomate-compatible facilities 12, a washbasin 13, a bed 14, a chair for infants 17, and a dressing table 18 are provided. The ostomate-compatible facilities 12 are a washbasin for the user to wash the stoma. A handrail 15 is provided between the toilet 11 and the ostomate-compatible facilities 12.

[0020] An emergency button 16, which is an emergency notification button or a panic call button provided on the wall near the toilet 11 inside the toilet cubicle 10 as the inside of the opening 102, is pressed in case of an emergency such as a user's poor physical condition during the use of the barrier-free toilet, to notify the occurrence of an emergency to the administrator of the public toilet or a third party outside the toilet cubicle 10.

[0021] An indoor information presentation unit 30 and an extension button 31 are provided on the wall near the ostomate-compatible facilities 12. The indoor information presentation unit 30 as a guidance unit is a device that presents guidance information such as the usage method of various facilities in the toilet cubicle 10 and the available time of the public toilet to the users in the toilet cubicle 10. The indoor information presentation unit 30 presents or notifies the guidance information to the users by means of the voice of a speaker, the display of a display, etc. When an available time (for example, 30 minutes) is set for the public toilet, the indoor information presentation unit 30 notifies various guidance information to the users according to the elapsed time since the user entered.

[0022] For example, the indoor information presentation unit 30 notifies the remaining available time, notifies that the available time has been exceeded, and notifies that the door 20 has been transitioned to an openable state or an unlocked state after the available time has been exceeded. Further, when the available time has been exceeded, it is notified to the administrator of the public toilet, and is also notified to a third party outside the toilet cubicle 10 by the outdoor information presentation unit 46 (the "in use" lamp goes out). When the extension button 31 is pressed by the user inside the toilet cubicle 10, the available time of the public toilet is extended by a predetermined time (for example, 10 minutes).

[0023] The automatic door device 100 drives the door 20 in the X direction to open and close a rectangular opening 102 in a front view (FIG. 2). The door 20 is a rectangular moving body that is slidably provided on a rail 22 that extends horizontally from a fully closed position on the right side to a fully open position on the left side in a front view. The automatic door device 100 includes contact operation detection units 24 and 26, non-contact switches 23 and 25 as non-contact operation detection units, and a door drive control unit 50.

[0024] The contact operation detection units 24 and 26 detect a contact operation (button pressing operation) of the user, generate an open instruction signal or a close instruction signal for the door 20 (hereinafter, may be collectively referred to as an open / close instruction signal or an instruction signal), and output it to the door drive control unit 50. The door drive control unit 50 opens and closes the door 20 based on the open / close instruction signal from the contact operation detection units 24 and 26. The outdoor contact operation detection unit 24 that can be operated from the outside of the toilet cubicle 10 includes a contact-type outdoor open switch 241 as an outdoor open operation unit that detects an open operation for opening the door 20, and a contact-type outdoor close switch 242 as an outdoor close operation unit that detects a close operation for closing the door 20.

[0025] Similarly, the indoor contact operation detection unit 26 that can be operated from the inside of the toilet room 10 includes a contact-type indoor open switch 261 as an indoor open operation unit that detects an open operation for opening the door 20, and a contact-type indoor close switch 262 as an indoor close operation unit that detects a close operation for closing the door 20. As schematically shown in FIG. 2, the outdoor contact operation detection unit 24 is provided on the outdoor side of the front wall 101, and the indoor contact operation detection unit 26 is provided on the indoor side of the front wall 101. The outdoor contact operation detection unit 24 and the indoor contact operation detection unit 26 may be provided on the outdoor side and the indoor side of the door 20, respectively.

[0026] The outdoor open switch 241, the outdoor close switch 242, the indoor open switch 261, and the indoor close switch 262 (hereinafter, may be collectively referred to as contact switches or open / close switches) can be configured by devices based on various principles capable of detecting a user's contact operation. Each contact switch 241, 242, 261, 262 in the present embodiment is a push-button switch that generates an open / close instruction signal when pressed. Specifically, the outdoor open switch 241 and the indoor open switch 261 (hereinafter, may be collectively referred to as open switches) generate an open instruction signal for the door 20 when pressed, and the outdoor close switch 242 and the indoor close switch 262 (hereinafter, may be collectively referred to as close switches) generate a close instruction signal for the door 20 when pressed.

[0027] Note that, as will be described later, each contact switch 241, 242, 261, 262 is made effective or ineffective according to the control state of the door 20 by the door drive control unit 50. For this reason, the open / close instruction signal is output to the door drive control unit 50 only when an effective contact switch 241, 242, 261, 262 is pressed, and even if an ineffective contact switch 241, 242, 261, 262 is pressed, the open / close instruction signal is not output to the door drive control unit 50. In addition, light-emitting elements such as LEDs (Light-Emitting Diodes) that emit light when each is effective are provided on each contact switch 241, 242, 261, 262 itself or around it, and users inside and outside the toilet room 10 can visually recognize which contact switch can be effectively operated.

[0028] The non-contact switches 23 and 25 are a single non-contact switch that is shared for opening and closing and outputs an operation signal that serves as the basis for an opening / closing instruction signal for the door 20 in response to a non-contact operation such as a user holding their hand over it, and can be configured by devices based on various principles capable of detecting the user's non-contact operation. As will be described later, the operation signal processing unit that receives the operation signal from the non-contact switches 23 and 25 outputs an opening instruction signal or a closing instruction signal for the door 20 to the door drive control unit 50 based on the valid / invalid state information of each of the contact switches 241, 242, 261, and 262. The door drive control unit 50 opens and closes the door 20 based on the opening / closing instruction signal from the operation signal processing unit.

[0029] The outdoor non-contact switch 23 that can be non-contact operated from the outside of the toilet room 10 is provided at an arbitrary position outside the toilet room 10 different from the outdoor contact operation detection unit 24. In the example of FIG. 2, the outdoor non-contact switch 23 is provided below the outdoor contact operation detection unit 24 on the outer surface of the front wall 101. Similarly, the indoor non-contact switch 25 that can be non-contact operated from the inside of the toilet room 10 is provided at an arbitrary position inside the toilet room 10 different from the indoor contact operation detection unit 26. In the example of FIG. 2, the indoor non-contact switch 25 is provided below the indoor contact operation detection unit 26 on the inner surface of the front wall 101. Thus, on the outside of the toilet room 10, the outdoor non-contact switch 23 and the outdoor contact operation detection unit 24 are provided in combination, and on the inside of the toilet room 10, the indoor non-contact switch 25 and the indoor contact operation detection unit 26 are provided in combination. A plurality of such switch units, each being a combination of one non-contact switch and two contact switches, may be provided on the outside and / or inside of the toilet room 10.

[0030] Note that the non-contact switches 23 and 25 may be provided integrally with the contact operation detection units 24 and 26, respectively. For example, an outdoor non-contact switch 23 may be provided between or around an outdoor open switch 241 and an outdoor close switch 242 in the outdoor contact operation detection unit 24, or an indoor non-contact switch 25 may be provided between or around an indoor open switch 261 and an indoor close switch 262 in the indoor contact operation detection unit 26. In this way, by integrating the contact switch and the non-contact switch on the outdoor side and / or the indoor side, a multi-switch device having different types of switches can be configured compactly and inexpensively. On the other hand, by separating the contact switch and the non-contact switch as shown in FIG. 2, the configuration of the switch device can be flexibly changed according to the installation location of the automatic door device 100. Other configuration examples or arrangement examples of the contact switch and the non-contact switch will be described later.

[0031] The door drive control unit 50 includes a door control unit 52 and a door drive unit 54. The door control unit 52 that controls the opening and closing of the door 20 based on the opening and closing instruction signal controls the opening and closing operation of the door 20 according to the user's contact operation and non-contact operation through the contact operation detection units 24 and 26 and the non-contact switches 23 and 25. The door drive unit 54, also called a door engine, drives the door 20 to open and close in the horizontal direction under the control of the door control unit 52. The door drive unit 54 can be configured by an annular belt (not shown) to which the door 20 is connected and a motor (not shown) that rotationally drives the belt. For example, the door drive unit 54 can be configured such that when the belt rotates in the clockwise direction, the door 20 moves in the opening direction (-X direction), and when the belt rotates in the counterclockwise direction, the door 20 moves in the closing direction (+X direction). Note that the door drive control unit 50 may be provided in the blind of the front wall 101.

[0032] The outdoor notification unit 44 provided outside the toilet room 10 notifies users outside the toilet room 10 or third parties of the occurrence of an emergency situation of the user inside the toilet room 10, a failure or abnormality that hinders the use of the public toilet, and the like. The outdoor notification unit 44 in the example of FIG. 2 includes an audio notification unit 441 such as a speaker that performs audio notification, and a light notification unit 442 such as a light emitting element or a display that performs notification by light or an image. Note that the indoor information presentation unit 30 described above performs the same function as the outdoor notification unit 44 for the user inside the toilet room 10.

[0033] Inside the toilet room 10, a presence detection unit 27 that detects the presence or absence of a person inside the toilet room 10 and an activity detection unit 28 that detects the activity status of a person inside the toilet room 10 are provided. The presence detection unit 27 is a human sensor composed of a pyroelectric element or the like that can detect infrared rays emitted by a person. The activity detection unit 28 is an object detection sensor having a detection area composed of a plurality of detection spots. For example, the activity detection unit 28 includes a plurality of light emitting elements that project infrared rays to each detection spot and a plurality of light receiving elements that receive reflected light from each detection spot. Based on the temporal change in the light reception result or detection result in the plurality of light receiving elements, the activity detection unit 28 determines whether the user is normally active inside the toilet room 10.

[0034] The presence detection unit 27 and the activity detection unit 28 can determine whether the user inside the toilet room 10 is normally active, so an abnormality can be quickly detected when an abnormality occurs. For example, when the presence detection unit 27 detects a person while the activity detection unit 28 does not detect activity for a certain period of time, there is a high possibility that an abnormality has occurred to the user inside the toilet room 10 detected by the presence detection unit 27. Also, when the presence detection unit 27 does not detect a person and the activity detection unit 28 also does not detect activity for a certain period of time, but the "in use" lamp of the outdoor information presentation unit 46 is lit, there is a high possibility that a failure or abnormality has occurred in the public toilet. An abnormality detected by the presence detection unit 27 and / or the activity detection unit 28, or the occurrence of an emergency situation due to the user inside the toilet room 10 pressing the emergency button 16 itself, is notified to the administrator of the public toilet and also notified to third parties outside the toilet room 10 by the outdoor notification unit 44 and the outdoor information presentation unit 46.

[0035] The door 20 is provided with a lock part (not shown) that restricts the movement of the closed door 20 under the control of the door drive control unit 50. The lock part may be constituted by an electric lock or the like that mechanically restricts the movement of the door 20 in the opening direction by locking using electromagnetic force or the like, or may be constituted by a disabling control unit or the like that electrically disables an opening instruction signal based on the operation of each contact switch and each non-contact switch in front of the door drive control unit 50 or in the door drive control unit 50. When the public toilet is being used by a user inside the toilet cubicle 10, the door drive control unit 50 mechanically or electrically restricts an opening operation through the outdoor opening switch 241 or the outdoor non-contact switch 23 by a user outside the toilet cubicle 10 by means of the lock part. At this time, although the outdoor opening switch 241 and the outdoor non-contact switch 23 are invalidated, since the light-emitting element such as an LED provided in the outdoor opening switch 241 is turned off and the "in use" lamp of the outdoor information display unit 46 is lit, a user outside the toilet cubicle 10 can visually recognize that the public toilet is being used by another user and that an opening operation of the door 20 is impossible.

[0036] FIG. 3 shows a functional block of the automatic door device 100 responsible for opening and closing control of the door 20 by each contact switch and each non-contact switch. The automatic door device 100 includes a switch device 60 in addition to the components described with reference to FIG. 1 or FIG. 2. The switch device 60 includes an indoor switch device 60I including an indoor non-contact switch 25 inside the toilet cubicle 10 and an outdoor switch device 60O including an outdoor non-contact switch 23 outside the toilet cubicle 10. Since the indoor switch device 60I and the outdoor switch device 60O have the same configuration if the inside and outside of the toilet cubicle 10 are distinguished, the same description is omitted by collectively referring to them as the switch device 60. In addition, the components of the indoor switch device 60I and the outdoor switch device 60O are given the same names and reference numerals except for the non-contact switches 25 and 23.

[0037] The switch device 60 includes a contact input circuit 61, a switch control unit 62, a state information acquisition unit 63, and a contact output circuit 64. These functional blocks are realized by the cooperation of hardware resources such as a central processing unit, a memory, an input device, an output device, and peripheral devices connected to a computer, and software executed using these resources. Regardless of the type and installation location of the computer, each of the above functional blocks may be realized by the hardware resources of a single computer, or may be realized by combining the hardware resources distributed among a plurality of computers. In particular, in this embodiment, part or all of the functional blocks of the switch device 60 may be realized by the door control unit 52 of the automatic door device 100 which is itself a computer, or may be realized by a microcontroller or an MCU (Micro Controller Unit) separate from the door control unit 52.

[0038] The contact input circuit 61 is a circuit to which signals from contact switches and non-contact switches are input. To the contact input circuit 61 in the indoor switch device 60I, an opening instruction signal for the door 20 (hereinafter sometimes abbreviated as an inner opening signal) corresponding to the pressing operation of the indoor open switch 261, a closing instruction signal for the door 20 (hereinafter sometimes abbreviated as an inner closing signal) corresponding to the pressing operation of the indoor close switch 262, and an operation signal (hereinafter sometimes referred to as an indoor operation signal) corresponding to the non-contact operation of the indoor non-contact switch 25 are input. To the contact input circuit 61 in the outdoor switch device 60O, an opening instruction signal for the door 20 (hereinafter sometimes abbreviated as an outer opening signal) corresponding to the pressing operation of the outdoor open switch 241, a closing instruction signal for the door 20 (hereinafter sometimes abbreviated as an outer closing signal) corresponding to the pressing operation of the outdoor close switch 242, and an operation signal (hereinafter sometimes referred to as an outdoor operation signal) corresponding to the non-contact operation of the outdoor non-contact switch 23 are input. As described above, the contact input circuit 61 constitutes an operation signal input unit to which an operation signal corresponding to the operation of a switch provided near the door 20 is input.

[0039] The contact input circuit 61 transmits signals from the input contact switches and non-contact switches to the switch control unit 62. The switch control unit 62 outputs an open / close instruction signal according to the contact operation of the contact switches 241, 242, 261, 262 by the user and the non-contact operation of the non-contact switches 23, 25 by the user. When the switch control unit 62 receives an operation signal from the non-contact switches 23, 25, it outputs an open instruction signal or a close instruction signal for the door 20 to the door control unit 52 based on the status information acquired by the status information acquisition unit 63. That is, the operation signals from the non-contact switches 23, 25 are converted by the switch control unit 62 into either an open instruction signal or a close instruction signal. Details of this operation signal processing will be described later. Note that when the switch control unit 62 receives an open instruction signal or a close instruction signal from a contact switch, it outputs them as they are. In this way, the switch control unit 62 in the indoor switch device 60I receives an in-opening signal from the indoor open switch 261, an in-closing signal from the indoor close switch 262, and an indoor operation signal from the indoor non-contact switch 25, and outputs an in-opening signal or an in-closing signal. Similarly, the switch control unit 62 in the outdoor switch device 60O receives an out-opening signal from the outdoor open switch 241, an out-closing signal from the outdoor close switch 242, and an outdoor operation signal from the outdoor non-contact switch 23, and outputs an out-opening signal or an out-closing signal.

[0040] The state information acquisition unit 63 acquires the valid / invalid state information of the open switch and the closed switch as contact switches from the door control unit 52. Specifically, the state information acquisition unit 63 acquires the valid / invalid state information of the open switch and the closed switch corresponding to the light emission state information of the light emitting elements provided in the open switch and the closed switch, respectively, from the door control unit 52. Note that the state information acquisition unit 63 may acquire the light emission state information of each light emitting element as the valid / invalid state information of the open switch and the closed switch. The state information acquisition unit 63 in the indoor switch device 60I acquires the state information that the indoor open switch 261 is valid if the light emitting element 263 provided in the indoor open switch 261 emits light continuously or intermittently, and the indoor open switch 261 is invalid otherwise, and acquires the state information that the indoor closed switch 262 is valid if the light emitting element 264 provided in the indoor closed switch 262 emits light continuously or intermittently, and the indoor closed switch 262 is invalid otherwise. The state information acquisition unit 63 in the outdoor switch device 60O acquires the state information that the outdoor open switch 241 is valid if the light emitting element 243 provided in the outdoor open switch 241 emits light continuously or intermittently, and the outdoor open switch 241 is invalid otherwise, and acquires the state information that the outdoor closed switch 242 is valid if the light emitting element 244 provided in the outdoor closed switch 242 emits light continuously or intermittently, and the outdoor closed switch 242 is invalid otherwise.

[0041] FIG. 4 shows a specific example of the determination process for the validity / invalidity of the contact switch based on the lighting state of the light emitting element. This determination process is mainly executed by the door control unit 52, but may also be executed by the state information acquisition unit 63 or the switch control unit 62. FIG. 4(A) shows the lighting state of the light emitting element as a binary signal or pulse of zero and non-zero. When the signal is zero, the light emitting element is turned off, and when the signal is non-zero, the light emitting element is turned on. FIG. 4(B) shows the clock in the determination process as a binary signal or pulse of zero and non-zero. The period of the clock in the illustrated example is 0.1 second. FIG. 4(C) shows the determination result of the validity / invalidity of the contact switch as a binary signal or pulse of zero and non-zero. When the signal is zero, the contact switch is invalid, and when the signal is non-zero, the contact switch is valid.

[0042] First, when the light-emitting element is lit at the rising timing of each clock, the contact switch is determined to be valid during each clock period (0.1 second). Also, when the light-emitting element transitions from being lit to being extinguished, instead of immediately invalidating the contact switch, it maintains the valid state for a predetermined time. In the illustrated example, the valid state of the contact switch is maintained for three clocks, that is, for 0.3 seconds. As shown on the right side of FIG. 4(A), during the opening and closing operation of the door 20 or in case of an emergency, the light-emitting element may blink. However, by providing a standby time (0.3 seconds) longer than this blinking period, the valid state of the contact switch can be appropriately maintained during the blinking of the light-emitting element. The numbers "1", "2", "3", and "4" shown in FIG. 4(C) represent the elapsed time in clock units with the rising timing of each clock as "1". When, after the light-emitting element transitions from being lit to being extinguished and counts up from "1" to "4" without lighting up again (when 0.3 seconds corresponding to three clocks have elapsed), the contact switch transitions from being valid to being invalid.

[0043] The contact output circuit 64 is a circuit that outputs a signal from the switch control unit 62 to the door control unit 52. The contact output circuit 64 in the indoor switch device 60I outputs an inner open signal or an inner close signal from the switch control unit 62 to the door control unit 52, and the contact output circuit 64 in the outdoor switch device 60O outputs an outer open signal or an outer close signal from the switch control unit 62 to the door control unit 52. When the door control unit 52 receives an inner open signal or an outer open signal as an open instruction signal, it drives the door 20 to open via the door drive unit 54, and when it receives an inner close signal or an outer close signal as a close instruction signal, it drives the door 20 to close via the door drive unit 54.

[0044] Next, the possible combinations of valid / invalid states and state transitions of the contact switches described with reference to FIG. 4 will be described. FIG. 5 shows the possible combinations of valid / invalid states of the contact switches 241 and 242 outside the toilet compartment 10, and the state transitions in response to the pressing operations of the contact switches 241 and 242. FIG. 6 shows the possible combinations of valid / invalid states of the contact switches 261 and 262 inside the toilet compartment 10, and the state transitions in response to the pressing operations of the contact switches 261 and 262.

[0045] In FIGS. 5 and 6, the door 20 mainly takes six states. In the first state, the public toilet is unused (unlocked) and the door 20 is fully closed. In the second state, the public toilet is unused and the door 20 is in the process of closing. In the third state, the public toilet is unused and the door 20 is fully open. In the fourth state, the public toilet is unused and the door 20 is in the process of opening. In the fifth state, the public toilet is in use (locked) and the door 20 is fully closed. In the sixth state, the public toilet is in use and the door 20 is in the process of closing (immediately locked when fully closed).

[0046] In FIG. 5 outside the toilet room 10, in the first state (unused / fully closed), the outdoor open switch 241 is valid and the outdoor close switch 242 is invalid. When a user outside the toilet room 10 presses the valid outdoor open switch 241, the door 20 starts an opening operation and transitions to the fourth state (unused / opening). In the second state (unused / closing), the outdoor open switch 241 is valid and the outdoor close switch 242 is invalid. When a user outside the toilet room 10 presses the valid outdoor open switch 241, the door 20 that is in a closing operation switches to an opening operation and transitions to the fourth state (unused / opening). In the third state (unused / fully open), the outdoor open switch 241 is invalid and the outdoor close switch 242 is valid. When a user outside the toilet room 10 presses the valid outdoor close switch 242, the door 20 starts a closing operation and transitions to the second state (unused / closing). In the fourth state (unused / opening), the outdoor open switch 241 is invalid and the outdoor close switch 242 is valid. When a user outside the toilet room 10 presses the valid outdoor close switch 242, the door 20 that is in an opening operation switches to a closing operation and transitions to the second state (unused / closing). In the fifth state (in use / fully closed) and the sixth state (in use / closing), both the outdoor open switch 241 and the outdoor close switch 242 are invalid.

[0047] As described above, the outdoor open switch 241 as an open switch outside the toilet room 10 is made valid or invalid according to the control state of the door 20 by the door control unit 52, and outputs an open instruction signal (outdoor open signal) for the door to the door control unit 52 according to the contact operation of the user outside the toilet room 10 when it is valid. Also, the light emitting element 243 provided in parallel with the outdoor open switch 241 emits light substantially in synchronization with the valid timing of the outdoor open switch 241 according to the process shown in FIG. 4. Similarly, the outdoor close switch 242 as a close switch outside the toilet room 10 is made valid or invalid according to the control state of the door 20 by the door control unit 52, and outputs a close instruction signal (outdoor close signal) for the door to the door control unit 52 according to the contact operation of the user outside the toilet room 10 when it is valid. Also, the light emitting element 244 provided in parallel with the outdoor close switch 242 emits light substantially in synchronization with the valid timing of the outdoor close switch 242 according to the process shown in FIG. 4.

[0048] In FIG. 6 within the toilet room 10, in the first state (unused / fully closed), the indoor open switch 261 is valid. When a user within the toilet room 10 presses the valid indoor open switch 261, the door 20 starts an opening operation and transitions to the fourth state (unused / opening). Also, in the first state (unused / fully closed), the indoor close switch 262 is also operable. When a user within the toilet room 10 presses the indoor close switch 262, the door 20 is locked and transitions to the fifth state (in use / fully closed). In the second state (unused / closing), the indoor open switch 261 is valid. When a user within the toilet room 10 presses the valid indoor open switch 261, the door 20 during a closing operation switches to an opening operation and transitions to the fourth state (unused / opening). Also, in the second state (unused / closing), the indoor close switch 262 is also operable. When a user within the toilet room 10 presses the indoor close switch 262, the door 20 transitions to the sixth state (in use / closing) (it is immediately locked when it reaches the fully closed state). In the third state (unused / fully open), the indoor open switch 261 is invalid and the indoor close switch 262 is valid. When a user within the toilet room 10 presses the valid indoor close switch 262, the door 20 starts a closing operation and transitions to the sixth state (in use / closing).

[0049] In the fourth state (unused / opening), the indoor open switch 261 is invalid. Also, when the door 20 is in the opening operation due to the pressing operation of the indoor open switch 261 or the non-contact operation of the indoor non-contact switch 25, the indoor close switch 262 is also invalid. On the other hand, when the door 20 is in the opening operation due to the pressing operation of the outdoor open switch 241 or the non-contact operation of the outdoor non-contact switch 23, the indoor close switch 262 is valid. When a user in the toilet room 10 presses the valid indoor close switch 262, the opening door 20 switches to the closing operation and transitions to the sixth state (in use / closing). In the fifth state (in use / fully closed), the indoor open switch 261 is valid and the indoor close switch 262 is invalid. When a user in the toilet room 10 presses the valid indoor open switch 261, the door 20 starts the opening operation and transitions to the fourth state (unused / opening). In the sixth state (in use / closing), the indoor open switch 261 is valid and the indoor close switch 262 is invalid. When a user in the toilet room 10 presses the valid indoor open switch 261, the closing door 20 switches to the opening operation and transitions to the fourth state (unused / opening).

[0050] As described above, the indoor open switch 261 as the open switch in the toilet room 10 is made valid or invalid according to the control state of the door 20 by the door control unit 52, and outputs an open instruction signal (inner open signal) for the door to the door control unit 52 according to the contact operation of the user in the toilet room 10 when it is valid. Also, the light-emitting element 263 provided in parallel with the indoor open switch 261 emits light substantially in synchronization with the valid timing of the indoor open switch 261 according to the process shown in FIG. 4. Similarly, the indoor close switch 262 as the close switch in the toilet room 10 is made valid or invalid according to the control state of the door 20 by the door control unit 52, and outputs a close instruction signal (inner close signal) for the door to the door control unit 52 according to the contact operation of the user in the toilet room 10 when it is valid. Also, the light-emitting element 264 provided in parallel with the indoor close switch 262 emits light substantially in synchronization with the valid timing of the indoor close switch 262 according to the process shown in FIG. 4.

[0051] Next, the opening and closing control of the door 20 by the non-contact switch will be described. The switch control unit 62 that has received an operation signal from the non-contact switch identifies the switch that is valid among the open switch and the close switch based on the valid / invalid state information of the open switch and the close switch acquired by the state information acquisition unit 63, and outputs an instruction signal corresponding to the instruction signal of the valid switch to the door control unit 52.

[0052] In FIG. 5 regarding the switch outside the toilet room 10, when a user outside the toilet room 10 non-contact-operates the outdoor non-contact switch 23 in the first state (unused / fully closed), assuming that the valid outdoor open switch 241 has been operated, the door 20 starts an opening operation and transitions to the fourth state (unused / opening). When a user outside the toilet room 10 non-contact-operates the outdoor non-contact switch 23 in the second state (unused / closing), assuming that the valid outdoor open switch 241 has been operated, the door 20 that is in a closing operation switches to an opening operation and transitions to the fourth state (unused / opening).

[0053] When a user outside the toilet room 10 non-contact-operates the outdoor non-contact switch 23 in the third state (unused / fully open), assuming that the valid outdoor close switch 242 has been operated, the door 20 starts a closing operation and transitions to the second state (unused / closing). When a user outside the toilet room 10 non-contact-operates the outdoor non-contact switch 23 in the fourth state (unused / opening), assuming that the valid outdoor close switch 242 has been operated, the door 20 that is in an opening operation switches to a closing operation and transitions to the second state (unused / closing). In the fifth state (in use / fully closed) and the sixth state (in use / closing), since both the outdoor open switch 241 and the outdoor close switch 242 are invalid, even if a user outside the toilet room 10 non-contact-operates the outdoor non-contact switch 23, the switch control unit 62 does not output either an outward opening signal or an outward closing signal for the door 20 to the door control unit 52.

[0054] In FIG. 6 regarding the switch in the toilet room 10, when a user in the toilet room 10 non - contact operates the indoor non - contact switch 25 in the first state (unused / fully closed), assuming that the effective indoor open switch 261 is operated, the door 20 starts an opening operation and transitions to the fourth state (unused / opening). When a user in the toilet room 10 non - contact operates the indoor non - contact switch 25 in the second state (unused / closing), assuming that the effective indoor open switch 261 is operated, the door 20, which is in a closing operation, switches to an opening operation and transitions to the fourth state (unused / opening). Here, in the first and second states in FIG. 6, the indoor close switch 262 can also be operated for locking, but the indoor non - contact switch 25 gives priority to the opening operation over the locking operation to prevent the user from being trapped by accidental locking in case of an emergency. In addition, in case a user in the toilet room 10 who non - contact operates the indoor non - contact switch 25 in the first or second state wants to perform a locking operation instead of the opening operation of the door 20, the indoor information presentation unit 30 may inform the user in the toilet room 10 that the door 20 can be locked by performing a non - contact operation on the indoor non - contact switch 25 again or pressing the indoor close switch 262.

[0055] When a user inside the toilet room 10 non - contact operates the indoor non - contact switch 25 in the third state (unused / full open), assuming that the effective indoor closed switch 262 has been operated, the door 20 starts a closing operation and transitions to the sixth state (in use / closing). When a user inside the toilet room 10 non - contact operates the indoor non - contact switch 25 in the fourth state (unused / opening), assuming that the effective indoor closed switch 262 (when the door 20 is in an opening operation by pressing the outdoor open switch 241 or non - contact operating the outdoor non - contact switch 23) has been operated, the door 20 in the opening operation switches to a closing operation and transitions to the sixth state (in use / closing). When a user inside the toilet room 10 non - contact operates the indoor non - contact switch 25 in the fifth state (in use / full closed), assuming that the effective indoor open switch 261 has been operated, the door 20 starts an opening operation and transitions to the fourth state (unused / opening). When a user inside the toilet room 10 non - contact operates the indoor non - contact switch 25 in the sixth state (in use / closing), assuming that the effective indoor open switch 261 has been operated, the door 20 in the closing operation switches to an opening operation and transitions to the fourth state (unused / opening).

[0056] When the door 20 is controlled to open and close based on the operation signals output by the non - contact switches 25 and 23 according to the descriptions of FIGS. 5 and 6, at the start or after the start of the opening and closing operation of the door 20, the valid / invalid state information of the open switches 261, 241 and the closed switches 262, 242 is updated by the door control unit 52. The door control unit 52 can detect the start of the opening and closing operation of the door 20 by a motor or belt of the door drive unit 54 or any principle position sensor (not shown) provided on the door 20. The valid / invalid state information of each contact switch updated by the door control unit 52 is provided to the state information acquisition unit 63 and the light - emitting elements provided in parallel with each contact switch.

[0057] Note that, regardless of the descriptions of FIGS. 5 and 6, during the interval of a predetermined time (e.g., 2 - 3 seconds) after the switch control unit 62 outputs an opening / closing instruction signal for the door 20 in response to the non-contact operations of the non-contact switches 25 and 23, the output of the operation signals from the non-contact switches 25 and 23 is invalidated, or the switch control unit 62 does not receive the operation signals from the non-contact switches 25 and 23. This can prevent the door 20 from repeatedly performing unnecessary opening / closing that is not intended by the user when the user's hand or the like continues to be held over the non-contact switches 25 and 23.

[0058] Also, when the opening instruction signal or closing instruction signal by the contact operation of the open switches 261 and 241 or the close switches 262 and 242 overlaps or conflicts with the opening instruction signal or closing instruction signal by the non-contact operation of the non-contact switches 25 and 23, the door control unit 52 controls the opening and closing of the door 20 according to the opening instruction signal or closing instruction signal by the contact operation of the open switches 261 and 241 or the close switches 262 and 242. Specifically, when the opening instruction signal from the open switches 261 and 241 or the closing instruction signal from the close switches 262 and 242 and the operation signal from the non-contact switches 25 and 23 are output within a predetermined time, the door control unit 52 controls the opening and closing of the door 20 according to the opening instruction signal from the open switches 261 and 241 or the closing instruction signal from the close switches 262 and 242. That is, the opening / closing instruction signal by the contact switches 261, 241, 262, and 242 is always prioritized over the opening / closing instruction signal by the non-contact switches 25 and 23 (however, refer to the modified example described later). Specifically, when the door control unit 52 receives the opening / closing instruction signal by the contact switches 261, 241, 262, and 242 and the opening / closing instruction signal by the non-contact switches 25 and 23 almost simultaneously, the opening / closing instruction signal by the non-contact switches 25 and 23 is ignored, and the door 20 is driven to open and close based on the opening / closing instruction signal by the contact switches 261, 241, 262, and 242.

[0059] Also, after the door 20 is driven to open or close based on the opening / closing instruction signals from the non-contact switches 25 and 23, if the opening / closing instruction signals from the contact switches 261, 241, 262, and 242 are input to the door control unit 52, the door 20 is driven to open or close based on the opening / closing instruction signals from the contact switches 261, 241, 262, and 242 even during the above-mentioned 2 - 3 second interval (however, refer to the modification example described later). In addition, after the door 20 is driven to open or close based on the opening / closing instruction signals from the contact switches 261, 241, 262, and 242, an interval may be provided to invalidate the opening / closing drive of the door 20 based on the opening / closing instruction signals from each non-contact switch 25 and 23. By making this interval longer than the above-mentioned 2 - 3 second interval, the priority of the opening / closing instruction signals from the contact switches 261, 241, 262, and 242 may be further increased.

[0060] Figure 7 is a flowchart showing the processing of the operation signals from the non-contact switches by the switch control unit 62. "S" in the description of the flowchart means step or process. This flowchart can be applied to the switch control unit 62 of either the indoor switch device 60I or the outdoor switch device 60O. Hereinafter, the switch control unit 62 of the indoor switch device 60I will be mainly described.

[0061] In S1, the indoor operation signal from the indoor non-contact switch 25 is input to the switch control unit 62 via the contact input circuit 61. In S2, the switch control unit 62 determines whether either the indoor open switch 261 or the indoor close switch 262 is invalid based on the status information acquired by the status information acquisition unit 63. If either the indoor open switch 261 or the indoor close switch 262 is invalid (Yes in S2), the processing ends without the door 20 being controlled to open or close. This corresponds to the fifth and sixth states in FIG. 5 and the fourth state in FIG. 6 (when the door 20 is in the opening operation due to the pressing operation of the indoor open switch 261 or the non-contact operation of the indoor non-contact switch 25).

[0062] If the answer is "No" in S2, proceed to S3, and the switch control unit 62 determines whether both the indoor open switch 261 and the indoor close switch 262 can be operated based on the status information acquired by the status information acquisition unit 63. If both the indoor open switch 261 and the indoor close switch 262 can be operated (if the answer is "Yes" in S3), proceed to S4, and the switch control unit 62 converts the indoor operation signal input in S1 into an inward open signal. This corresponds to the first and second states in FIG. 6 where, in addition to the effective indoor open switch 261, the indoor close switch 262 can also be operated for locking. If the answer is "No" in S3, proceed to S5, and the switch control unit 62 determines whether the indoor open switch 261 is effective based on the status information acquired by the status information acquisition unit 63.

[0063] If the indoor open switch 261 is ineffective and the indoor close switch 262 is effective (if the answer is "No" in S5), proceed to S6, and the switch control unit 62 converts the indoor operation signal input in S1 into an inward close signal. This corresponds to the third and fourth states in FIG. 5 and the third and fourth states in FIG. 6 (when the door 20 is in the opening operation due to the pressing operation of the outdoor open switch 241 or the non-contact operation of the outdoor non-contact switch 23). If the indoor open switch 261 is effective and the indoor close switch 262 is ineffective (if the answer is "Yes" in S5), proceed to S7, and the switch control unit 62 converts the indoor operation signal input in S1 into an inward open signal. This corresponds to the first and second states in FIG. 5 and the fifth and sixth states in FIG. 6.

[0064] In the above embodiments, the non-contact switches 23 and 25 are exemplified as the switches for both opening and closing. However, a contact switch such as a push-button switch may be provided as the switch for both opening and closing. In this case, in addition to the non-contact switches 23 and 25 in FIG. 3, a contact switch for both opening and closing is provided inside and outside the toilet room 10.

[0065] In the above-described embodiments, light-emitting elements indicating the effective states of the respective contact switches 241, 242, 261, and 262 are provided, and the respective light-emitting state information is used as the effective / invalid state information of the respective contact switches 241, 242, 261, and 262. However, since state information similar to that in FIGS. 5 and 6 is held in the door control unit 52 regardless of the presence or absence of the light-emitting elements, the light-emitting elements may not be provided in the respective contact switches 241, 242, 261, and 262.

[0066] In FIGS. 5 and 6, the states (the first, third, and fifth states) in which the door 20 is maintained at the fully open position or the fully closed position have been described. However, the door 20 may be maintained in the open state at a position less than fully open. When the switch control unit 62 receives an operation signal from the contact input circuit 61 serving as the operation signal input unit in this state, the switch control unit 62 outputs an open instruction signal for the door 20 to the door control unit 52.

[0067] FIG. 8 shows a configuration example or an arrangement example of a contact switch and a non-contact switch. FIG. 8(A) shows a configuration example similar to FIG. 2. A contact operation detection unit 24 (26) including an open switch 241 (261) and a closed switch 242 (262) as contact switches and an open / close common non-contact switch 23 (25) are provided separately and side by side. Near the open switch 241 (261), a Braille display 291 meaning "open switch" for notifying a user with a visual impairment or the like of the presence of the open switch 241 (261) is provided. Similarly, near the closed switch 242 (262), a Braille display 292 meaning "closed switch" for notifying a user with a visual impairment or the like of the presence of the closed switch 242 (262) is provided. The Braille display 291 of the open switch 241 (261) and the Braille display 292 of the closed switch 242 (262) are collectively referred to as the Braille display 29 hereinafter. As will be described later, each Braille display 29 is provided with a contact detection unit for detecting contact of a user's hand or the like.

[0068] In FIGS. 8(B) and (C), the indoor-side reference numerals (such as 261) are omitted, but the following description of the outdoor-side configuration (such as 241) also applies to the indoor-side configuration. In FIG. 8(B), the non-contact switch is integrally formed with the contact switch. Specifically, the non-contact normally-open switch 231 of the non-contact type is integrally formed with the normally-open switch 241 of the contact type, and the non-contact normally-closed switch 232 of the non-contact type is integrally formed with the normally-closed switch 242 of the contact type. The non-contact normally-open switch 231 is a non-contact switch that outputs an open instruction signal for the door 20 in response to a non-contact operation such as holding a user's hand over it, and the non-contact normally-closed switch 232 is a non-contact switch that outputs a close instruction signal for the door 20 in response to a non-contact operation such as holding a user's hand over it. As shown in FIG. 8(C), each of the non-contact switches 231 and 232 for opening and closing may be formed separately from each of the contact switches 241 and 242 for opening and closing.

[0069] Similar to the contact switches 241 and 242, the non-contact switches 231 and 232 are made effective or ineffective according to the control state of the door 20 by the door drive control unit 50. For this reason, an opening / closing instruction signal is output to the door drive control unit 50 only when each of the effective non-contact switches 231 and 232 is non-contact-operated, and even if each of the ineffective non-contact switches 231 and 232 is non-contact, the opening / closing instruction signal is not output to the door drive control unit 50. The effective / ineffective states of the non-contact switches 231 and 232 respectively coincide with the effective / ineffective states of the contact switches 241 and 242.

[0070] When the open switch 241 is active, the non-contact open switch 231 is also active. If the user's hand or the like is held over the non-contact open switch 231 for a predetermined time or more without the open switch 241 being pressed, it is determined that there has been a non-contact operation of the non-contact open switch 231, and the non-contact open switch 231 outputs an open instruction signal to the door control unit 52. On the other hand, if the open switch 241 is pressed before the time that the user's hand or the like is held over the non-contact open switch 231 reaches the predetermined time, it is determined that there has been no non-contact operation of the non-contact open switch 231, and the pressed open switch 241 rather than the non-contact open switch 231 outputs an open instruction signal to the door control unit 52.

[0071] When the close switch 242 is active, the non-contact close switch 232 is also active. If the user's hand or the like is held over the non-contact close switch 232 for a predetermined time or more without the close switch 242 being pressed, it is determined that there has been a non-contact operation of the non-contact close switch 232, and the non-contact close switch 232 outputs a close instruction signal to the door control unit 52. On the other hand, if the close switch 242 is pressed before the time that the user's hand or the like is held over the non-contact close switch 232 reaches the predetermined time, it is determined that there has been no non-contact operation of the non-contact close switch 232, and the pressed close switch 242 rather than the non-contact close switch 232 outputs a close instruction signal to the door control unit 52.

[0072] FIG. 9 shows a functional block diagram of the automatic door device 100 corresponding to the switch configuration of FIG. 8(B) or (C). The main differences from the functional block diagram of FIG. 3 are that non-contact switches 231(251) and 232(252) for opening and closing are provided, and the state information acquisition unit 63 is not provided. In the outdoor switch device 60O, an outdoor non-contact open switch 231 and an outdoor non-contact close switch 232 are provided instead of the outdoor non-contact switch 23 of FIG. 3, and in the indoor switch device 60I, an indoor non-contact open switch 251 and an indoor non-contact close switch 252 are provided instead of the indoor non-contact switch 25 of FIG. 3.

[0073] In the contact input circuit 61 of the outdoor switch device 60O, in addition to the open and closed signals from the contact switches 241 and 242, the open and closed signals from the non-contact switches 231 and 232 are input. In the contact input circuit 61 of the indoor switch device 60I, in addition to the open and closed signals from the contact switches 261 and 262, the open and closed signals from the non-contact switches 251 and 252 are input.

[0074] The contact input circuit 61 transmits the open / close instruction signals from the input contact switches and non-contact switches to the switch control unit 62. In principle, the switch control unit 62 outputs the open / close instruction signals input to the contact input circuit 61 as they are to the contact output circuit 64. As will be described later, the switch control unit 62 restricts the control based on contact or non-contact switches according to the situation. Specifically, when restricting the control based on the contact switches 241, 242, 261, and 262, the switch control unit 62 does not output the open / close instruction signals output by the contact switches 241, 242, 261, and 262 to the contact output circuit 64 or the door control unit 52. Similarly, when restricting the control based on the non-contact switches 231, 232, 251, and 252, the switch control unit 62 does not output the open / close instruction signals output by the non-contact switches 231, 232, 251, and 252 to the contact output circuit 64 or the door control unit 52. The contact output circuit 64 outputs the open / close instruction signals from the switch control unit 62 to the door control unit 52.

[0075] FIG. 10 shows a functional block of the automatic door device 100 for restricting the control based on contact or non-contact switches by at least one of the door control unit 52 and the switch control unit 62. The same components as those in FIG. 3 and / or FIG. 9 are denoted by the same reference numerals and redundant descriptions are omitted. In addition, the illustration of the components (such as light emitting elements) related to the effective / invalid states of each contact switch for opening and closing and each non-contact switch for opening and closing is omitted.

[0076] The switch device 60 further includes a control restriction unit 65 and a contact detection unit 66. Although the control restriction unit 65 is illustrated as a component separate from the door control unit 52 and the switch control unit 62, the control restriction unit 65 may be implemented as a function in at least one of the door control unit 52 and the switch control unit 62. Also, although the contact detection unit 66 is illustrated as a component separate from the braille displays 291 and 292 inside and outside the toilet room 10, the actual contact detection unit 66 is a functional unit including the contact sensors provided on the respective braille displays 291 and 292.

[0077] When one type of switch, either the contact switch or the non-contact switch, is operated, the control restriction unit 65 restricts the control based on the other type of switch. Although details will be described later, it is considered that the user who operates one type of switch intends to preferentially operate that one type of switch. Thus, the purpose is to restrict the control based on the other type of switch with lower priority. Specifically, when the contact switches 241, 242, 261, 262 inside and / or outside the toilet room 10 are operated, the control restriction unit 65 restricts the control based on the non-contact switches 231, 232, 251, 252 inside and / or outside the toilet room 10. Similarly, when the non-contact switches 231, 232, 251, 252 inside and / or outside the toilet room 10 are operated, the control restriction unit 65 restricts the control based on the contact switches 241, 242, 261, 262 inside and / or outside the toilet room 10.

[0078] When the function of the control restriction unit 65 is implemented in the door control unit 52, the control restriction unit 65 restricts the control based on the other method switch by not performing the opening and closing control of the door 20 based on the opening and closing instruction signal according to the operation of the other method switch by the user. Specifically, after the contact switches 241, 242, 261, 262 inside and / or outside the toilet room 10 are operated, the door control unit 52 ignores the opening and closing instruction signal based on the non-contact operation of the non-contact switches 231, 232, 251, 252 inside and / or outside the toilet room 10, and does not perform the opening and closing control of the door 20 based on the opening and closing instruction signal. Similarly, after the non-contact switches 231, 232, 251, 252 inside and / or outside the toilet room 10 are operated, the door control unit 52 ignores the opening and closing instruction signal based on the contact operation of the contact switches 241, 242, 261, 262 inside and / or outside the toilet room 10, and does not perform the opening and closing control of the door 20 based on the opening and closing instruction signal.

[0079] When the function of the control restriction unit 65 is implemented in the switch control unit 62, the control restriction unit 65 restricts the control based on the other method switch by not outputting the opening and closing instruction signal according to the operation of the other method switch by the user. Specifically, after the contact switches 241, 242, 261, 262 inside and / or outside the toilet room 10 are operated, the switch control unit 62 does not output the opening and closing instruction signal based on the non-contact operation of the non-contact switches 231, 232, 251, 252 inside and / or outside the toilet room 10 to the door control unit 52. Similarly, after the non-contact switches 231, 232, 251, 252 inside and / or outside the toilet room 10 are operated, the switch control unit 62 does not output the opening and closing instruction signal based on the contact operation of the contact switches 241, 242, 261, 262 inside and / or outside the toilet room 10 to the door control unit 52.

[0080] The control restriction unit 65 implemented in the switch control unit 62 may restrict the control based on the other type of switch by changing the output condition of the open / close instruction signal in response to the operation of the other type of switch by the user. Specifically, when the switch control unit 62 restricts the control based on the non-contact switches 231, 232, 251, 252, it narrows the detection range of the user's hand or the like held over each non-contact switch 231, 232, 251, 252, increases the detection signal level of the user's hand or the like for each non-contact switch 231, 232, 251, 252 to output the open / close instruction signal, or increases the continuous detection time of the user's hand or the like for each non-contact switch 231, 232, 251, 252 to output the open / close instruction signal, thereby changing the output condition of the open / close instruction signal by the non-contact switches 231, 232, 251, 252. Also, when the switch control unit 62 restricts the control based on the contact switches 241, 242, 261, 262, it increases the intensity or speed of the contact operation (pressing operation) by the user for each contact switch 241, 242, 261, 262 to output the open / close instruction signal, or increases the continuous time of the contact operation (pressing operation) by the user for each contact switch 241, 242, 261, 262 to output the open / close instruction signal, thereby changing the output condition of the open / close instruction signal by the contact switches 241, 242, 261, 262.

[0081] In addition to or instead of the above, when the contact detection unit 66 that detects contact with each Braille display 291, 292 inside and outside the toilet room 10 enters the detection state, the control restriction unit 65 restricts the control based on the non-contact switches 231, 232, 251, 252. Although details will be described later, since a user who touches each Braille display 291, 292 inside and outside the toilet room 10 for a predetermined time or more is considered to have a visual impairment or the like, the purpose is to restrict the control based on the non-contact switches 231, 232, 251, 252 that may cause an incorrect operation. The mode of restricting the control of the non-contact switches 231, 232, 251, 252 by the door control unit 52 and / or the switch control unit 62 in which such a control restriction unit 65 is implemented is as described above.

[0082] Specifically, the door control unit 52 in which the control restriction unit 65 is implemented restricts the control based on the non-contact switches 231, 232, 251, and 252 by not performing the opening and closing control of the door based on the opening and closing instruction signal according to the operation of the non-contact switches 231, 232, 251, and 252 by the user. Further, the switch control unit 62 in which the control restriction unit 65 is implemented restricts the control based on the non-contact switches 231, 232, 251, and 252 by not outputting the opening and closing instruction signal according to the operation of the non-contact switches 231, 232, 251, and 252 by the user. Note that the switch control unit 62 in which the control restriction unit 65 is implemented may restrict the control based on the non-contact switches 231, 232, 251, and 252 by changing the output condition of the opening and closing instruction signal according to the operation of the non-contact switches 231, 232, 251, and 252 by the user.

[0083] When the control based on the contact switch or the non-contact switch is restricted by the control restriction unit 65, the indoor information presentation unit 30 as the indoor guide unit and / or the outdoor notification unit 44 as the outdoor guide unit change the content of the operation guide by voice or the like for the user to the content only for the switches of the system in which the control is not restricted. As described above, since it is considered that the user preferentially operates the switches of the system in which the control is not restricted, the intention is to omit the voice operation guide and the like of the switches of the system in which the control is restricted. Specifically, when the control based on the non-contact switches 231, 232, 251, and 252 is restricted by the control restriction unit 65, the indoor information presentation unit 30 and / or the outdoor notification unit 44 change to the voice operation guide and the like only for the contact switches 241, 242, 261, and 262. Similarly, when the control based on the contact switches 241, 242, 261, and 262 is restricted by the control restriction unit 65, the indoor information presentation unit 30 and / or the outdoor notification unit 44 change to the voice operation guide and the like only for the non-contact switches 231, 232, 251, and 252.

[0084] After the control based on the contact switch or the non-contact switch is restricted by the control restriction unit 65, if the inner contact switch 261 or the inner non-contact switch 251 is operated to open the door 20, the control restriction unit 65 releases the restriction on the control of the switch. When the inner open switches 261 and 251 are operated to open the door 20, it is considered that the user has finished using the public toilet, so the restriction on the control of the switch is released for the next user.

[0085] Also, after the control based on the contact switch or the non-contact switch is restricted by the control restriction unit 65, if the emergency button 16 in the toilet compartment 10 is operated, the control restriction unit 65 releases the restriction on the control of the switch. In the emergency situation where the emergency button 16 is operated, it is considered important to make it easier to open the door 20 for the user in the toilet compartment 10 to call for help from a third party outside the toilet compartment 10 or to escape outside the toilet compartment 10. Therefore, the purpose is to enable the control of both types of switches.

[0086] FIG. 11 is a flowchart showing a first processing example of restricting the control of the contact or non-contact switch by the door control unit 52 and / or the switch control unit 62 in which the control restriction unit 65 is implemented. Note that the possible combinations and state transitions of the validity / invalidity of the contact switch (and non-contact switch) described in FIGS. 5 and 6 also apply to the following description. For example, in the following, the restriction on the control of the contact switch and / or the non-contact switch will be described. However, a switch that is originally invalid is invalid regardless of the control restriction. That is, the "restriction on the control of the switch" in the following description applies to either the valid switch, strictly speaking, either one of the same type (outward opening / outward closing / inward opening / inward closing) of contact switch and non-contact switch that are simultaneously valid.

[0087] At the start of FIG. 11, it is assumed that the public toilet is unused and door 20 is fully closed. In this state, there is no person in toilet compartment 10, and a user outside toilet compartment 10 can open door 20 by operating outdoor open switch 241 or outdoor non-contact open switch 231 (the first state in FIG. 5). In S11, it is determined whether outdoor open switch 241 has been contact-operated. If outdoor open switch 241 has been contact-operated and door 20 has been opened (Yes in S11), the process proceeds to S12. In S12 corresponding to the third or fourth state in FIG. 6, it is determined whether indoor close switch 262 has been contact-operated. If indoor close switch 262 has been contact-operated and door 20 has been closed (Yes in S12), the process proceeds to S13.

[0088] Up to reaching S13, both outdoor open switch 241 in S11 and indoor close switch 262 in S12 have been contact-operated and door 20 has been opened and closed. Therefore, in S13, since it is considered that the user intends to preferentially operate contact switches, control based on non-contact switches 251 and 252 with lower priority is restricted, and only contact switches 261 and 262 are substantially made effective. Thus, when outer contact switch 241 is operated to open door 20 and then inner contact switch 262 is operated to close door 20, control based on non-contact switches 251 and 252 as the other type of switch is restricted. In S14, indoor information presentation unit 30 changes the content of the operation guidance by voice or the like for the user in toilet compartment 10 to the content only for effective contact switches 261 and 262.

[0089] If outdoor open switch 241 has not been contact-operated in S11 (No), the process proceeds to S15. In S15, it is determined whether outdoor non-contact open switch 231 has been non-contact-operated. If outdoor non-contact open switch 231 has been non-contact-operated and door 20 has been opened (Yes in S15), the process proceeds to S16. In S16 corresponding to the third or fourth state in FIG. 6, it is determined whether indoor non-contact close switch 252 has been non-contact-operated. If indoor non-contact close switch 252 has been non-contact-operated and door 20 has been closed (Yes in S16), the process proceeds to S17.

[0090] Until reaching S17, the outdoor non-contact open switch 231 at S15 and the indoor non-contact closed switch 252 at S16 are both non-contact operated to open and close the door 20. Thus, at S17, it is considered that the user intends to preferentially operate the non-contact type switch. In this case, the control restriction unit 65 may restrict the control based on the contact type switches 261 and 262 with low priority and substantially enable only the non-contact type switches 251 and 252. However, since the contact type switches 261 and 262 have a lower possibility of malfunction compared to the non-contact type switches 251 and 252, in the example of FIG. 11, both the contact type switches 261 and 262 and the non-contact type switches 251 and 252 are enabled (control is not restricted). On the other hand, at S18, the indoor information presentation unit 30 changes the content of the operation guidance by voice or the like for the user in the toilet room 10 to the content only for the non-contact type switches 251 and 252 with high priority. That is, the voice operation guidance for the contact type switches 261 and 262 with low priority is omitted.

[0091] If the indoor closed switch 262 is not contact-operated at S12 (No), the process proceeds to S19. At S19 corresponding to the third or fourth state in FIG. 6, it is determined whether the indoor non-contact closed switch 252 has been non-contact operated. If the indoor non-contact closed switch 252 has been non-contact operated and the door 20 has been closed (Yes at S19), the process proceeds to S20.

[0092] As described above, until reaching S20, the door 20 is opened and closed by the contact operation of the outdoor open switch 241 at S11 and the non-contact operation of the indoor non-contact closed switch 252 at S19. Since different types of switches are operated when opening outward and closing inward, it is impossible to determine whether the user intends to preferentially operate either type of switch. Therefore, at S20, control based on either type of switch is not restricted. At S21, the indoor information presentation unit 30 provides operation guidance for both types of switches to the user in the toilet room 10 by voice or the like.

[0093] If the indoor non-contact closing switch 252 is not non-contact operated at S16 (No), the process proceeds to S22. At S22 corresponding to the third or fourth state in FIG. 6, it is determined whether the indoor closing switch 262 has been contact-operated. If the indoor closing switch 262 has been contact-operated and the door 20 has been closed (Yes at S22), the process proceeds to S20.

[0094] As described above, until reaching S20, the door 20 is opened and closed by the non-contact operation of the outdoor non-contact opening switch 231 at S15 and the contact operation of the indoor closing switch 262 at S22. Since switches of different methods are operated when opening outward and closing inward in this way, it is impossible to determine whether the user intends to preferentially operate the switch of either method. Therefore, at S20, control based on either method of switch is not restricted. At S21, the indoor information presentation unit 30 provides operation guidance for both methods of switches to the user inside the toilet room 10 by voice or the like.

[0095] FIG. 12 is a flowchart showing a second processing example of restricting the control of the switch when the public toilet is not in use and the door 20 is in the fully open state. In this state, there is no one inside the toilet room 10, and a user outside the toilet room 10 enters from the fully open door 20 and can close the door 20 by operating the indoor closing switch 262 or the indoor non-contact closing switch 252 (the third state in FIG. 6). The same reference numerals are given to the same steps as in FIG. 11, and duplicate explanations are omitted.

[0096] In S12, it is determined whether the indoor closing switch 262 has been subjected to a contact operation. If the indoor closing switch 262 has been subjected to a contact operation and the door 20 has been closed (Yes in S12), the process proceeds to S13. By the time reaching S13, the indoor closing switch 262 in S12 has been subjected to a contact operation and the door 20 has been closed. Therefore, in S13, since it is considered that the user intends to preferentially operate the contact switch, the control based on the non-contact switches 251 and 252 with low priority is restricted, and only the contact switches 261 and 262 are substantially enabled. In this way, when the inner contact switch 262 is operated and the door 20 is closed when the door 20 is in the fully open state, the control based on the non-contact switches 251 and 252 as the other type of switches is restricted. In S14, the indoor information presentation unit 30 changes the content of the operation guidance by voice or the like for the user in the toilet room 10 to the content only for the valid contact switches 261 and 262.

[0097] If the indoor closing switch 262 has not been subjected to a contact operation in S12 (No), the process proceeds to S16. In S16, it is determined whether the indoor non-contact closing switch 252 has been subjected to a non-contact operation. If the indoor non-contact closing switch 252 has been subjected to a non-contact operation and the door 20 has been closed (Yes in S16), the process proceeds to S17. By the time reaching S17, the indoor non-contact closing switch 252 in S16 has been subjected to a non-contact operation and the door 20 has been closed. Thus, in S17, it is considered that the user intends to preferentially operate the non-contact switch. In this case, the control restriction unit 65 may restrict the control based on the contact switches 261 and 262 with low priority and substantially enable only the non-contact switches 251 and 252. However, since the contact switches 261 and 262 have a lower possibility of malfunction compared to the non-contact switches 251 and 252, in the example of FIG. 12, both the contact switches 261 and 262 and the non-contact switches 251 and 252 are enabled (the control is not restricted). On the other hand, in S18, the indoor information presentation unit 30 changes the content of the operation guidance by voice or the like for the user in the toilet room 10 to the content only for the non-contact switches 251 and 252 with high priority. That is, the voice operation guidance for the contact switches 261 and 262 with low priority is omitted.

[0098] Fig. 13 is a flow chart showing the process of releasing the restriction on switch control subsequent to Fig. 11 or 12. In S23, it is determined whether or not a switch that is not disabled among the indoor open switch 261 and the indoor non-contact open switch 251 has been operated by a user in the toilet 10. If No in S23, the process proceeds to S27, where it is determined whether or not the emergency button 16 has been operated. If No in S27, the process returns to S23, and the processes of S23 and S27 are repeated until the indoor open switch 261, the indoor non-contact open switch 251, or the emergency button 16 is operated. If Yes in S27, the process proceeds to S26, which will be described later. If Yes in S23, the process proceeds to S24, where it is determined whether or not a switch that is not disabled among the outdoor close switch 242 and the outdoor non-contact close switch 232 has been operated from outside the toilet 10.

[0099] If the answer is Yes in S24, the process proceeds to S26, which will be described later. If the answer is No in S24, the process proceeds to S25, where it is determined whether or not the door 20 has been fully closed. After the user in the toilet stall 10 who has finished using the public toilet operates the indoor open switch 261 or the indoor non-contact open switch 251 to open the door 20 in S23, if a predetermined time has passed in S24 without the outdoor close switch 242 or the outdoor non-contact close switch 232 being operated, the door 20 is configured to close automatically. If the door 20 closes automatically in this way, the answer is Yes in S25, and the process proceeds to S26. If the answer is No in S25, the process proceeds to S28, where it is determined whether or not the emergency button 16 has been operated. If the answer is No in S28, the process returns to S24. If the answer is Yes in S28, the process proceeds to S26.

[0100] In S26, since the use of the public toilet has ended, the control restriction unit 65 activates the non-contact switches 231, 232, 251, and 252 whose control was restricted in FIG. 11 or FIG. 12 for the next user. If the control of the contact switches 241, 242, 261, and 262 is restricted in FIG. 11 or FIG. 12, the restriction may be released in S26. Also, in S23, if it is determined that the use of the public toilet has ended because the indoor open switch 261 or the indoor non-contact open switch 251 has been operated, the restriction release process of S26 may be performed without going through the processes of S24 and S25. In this way, when the inner contact switch 261 or the inner non-contact switch 251 is operated and the door 20 is opened, the control restriction unit 65 releases the restriction on the control of the switch.

[0101] FIG. 14 is a flowchart showing a third processing example of restricting the control of the switch using the contact detection unit 66. In S31, the contact detection unit 66 detects contact of the user's hand or the like with the braille displays 291 and 292 inside and outside the toilet cubicle 10 and enters the detection state. Here, in order to exclude the case where the user's hand or the like accidentally contacts the braille displays 291 and 292, the contact detection unit 66 may transition to the detection state when the contact state with the braille displays 291 and 292 continues for a predetermined time or longer. In S32, it is determined whether the public toilet is unused and the door 20 is in the fully closed state. If Yes in S32, the process proceeds to S33, and the control restriction unit 65 invalidates or restricts the control based on the non-contact switches 231, 232, 251, and 252 inside and outside the toilet cubicle 10, and enables only the contact switches 241, 242, 261, and 262 inside and outside the toilet cubicle 10. When the public toilet is unused and the door 20 is in the fully closed state (Yes in S32), a user who has touched the braille displays 291 and 292 outside the toilet cubicle 10 for a predetermined time or longer has a visual impairment or the like and is considered to use the public toilet next, so the control based on the non-contact switches 231, 232, 251, and 252 that may cause an accidental operation is restricted (S33).

[0102] If the answer is No at S32, the process proceeds to S34, and it is determined whether the contact with each of the braille displays 291 and 292 at S31 was made when the state of the public toilet shifted from "unused" to "in use". Specifically, it is determined whether the contact with each of the braille displays 291 and 292 at S31 was made while transitioning from any one of the first to fourth "unused" states in FIG. 6 to the sixth "in use" state when the indoor closed switch 262 or the indoor non-contact closed switch 252 is operated. If the answer is Yes at S34, the process proceeds to S33, and the control restriction unit 65 invalidates or restricts the control based on the non-contact switches 231, 232, 251, and 252 inside and outside the toilet compartment 10, and enables only the contact switches 241, 242, 261, and 262 inside and outside the toilet compartment 10. When the state of the public toilet shifts from "unused" to "in use" (Yes at S34), a user who has touched each of the braille displays 291 and 292 inside and outside the toilet compartment 10 for a predetermined time or more is considered to have a visual impairment or the like and to be about to use the public toilet, so the control based on the non-contact switches 231, 232, 251, and 252 that may cause an incorrect operation is restricted (S33).

[0103] At S35, it is determined whether the public toilet has actually become "in use". If the answer is No at S35, the process returns to S32. At this time, the control restriction unit 65 may enable the non-contact switches 231, 232, 251, and 252 whose control was invalidated at S33. If the answer is Yes at S35, the process proceeds to S36, and it is determined whether the public toilet is unused and the door 20 has returned to the fully closed state, in other words, whether the use of the public toilet has ended. If the answer is No at S36, the process of S36 is repeated until the use of the public toilet ends. If the answer is Yes at S36, the process proceeds to S37, and the control restriction unit 65 enables the non-contact switches 231, 232, 251, and 252 whose control was invalidated at S33 for the next user.
