Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the automatic door device described in the above Patent Document 1, when an abnormality occurs in the forced unlocking switch, the lock mechanism cannot be forcibly unlocked from the forced unlocking switch, and the door opening operation becomes complicated in an emergency. For this reason, there is a demand for an automatic door device that can open the door from the outside in an emergency even if an abnormality occurs in the forced unlocking switch.

Means for Solving the Problems

[0005] The automatic door device for solving the above problems includes a door provided at the entrance of a private room and automatically driven to open and close, an electric lock for locking the door, an electric lock control unit for controlling locking and unlocking of the electric lock, a forced unlocking switch provided outside the private room and outputting an unlocking signal for unlocking the electric lock to the electric lock control unit when operated, and a determination unit for determining whether the forced unlocking switch is abnormal. When the determination unit determines that the forced unlocking switch is abnormal, the electric lock control unit invalidates the locking of the electric lock.

[0006] According to the above configuration, the determination unit grasps the abnormality of the forced unlocking switch, and when the forced unlocking switch is abnormal, the electric lock control unit invalidates the locking of the electric lock. Therefore, even if an abnormality occurs in the forced unlocking switch, the electric lock is not locked, so the door can be opened from the outside in an emergency.

[0007] Regarding the above automatic door device, when the determination unit determines that the forced unlocking switch is abnormal, if the electric lock control unit is locking the electric lock, it is preferable that the electric lock control unit unlocks the electric lock and does not lock it after unlocking.

[0008] Regarding the above automatic door device, when the determination unit determines that the forced unlocking switch is abnormal, if the electric lock control unit is unlocking the electric lock, it is preferable that the electric lock control unit continues to unlock the electric lock.

[0009] Regarding the above automatic door device, it includes a drive control unit for controlling the opening and closing drive of the door, an outside opening operation unit provided outside the private room and outputting an opening and closing instruction of the door to the drive control unit. The determination unit preferably determines whether the forced unlocking switch is abnormal when an opening instruction is received from the outside opening operation unit.

[0010] Regarding the above automatic door device, it includes a drive control unit for controlling the opening and closing drive of the door. When the determination unit determines that the forced unlocking switch is abnormal, it is preferable to perform a pressing operation of continuously driving the door in the closing direction at the fully closed position of the door.

[0011] Regarding the above automatic door device, it is provided inside the private room and includes an emergency output unit that outputs an emergency signal by the operation of the user of the private room. When the determination unit determines that the forced unlocking switch is abnormal, when the emergency signal is being output from the emergency output unit, it is preferable that the drive control unit reduces the pressing force for continuously driving the door in the closing direction below that of a normal pressing operation.

[0012] Regarding the above automatic door device, it includes a drive control unit that controls the opening and closing drive of the door, and an emergency output unit that is provided inside the private room and outputs an emergency signal by the operation of the user of the private room. When the determination unit determines that the forced unlocking switch is abnormal, when the emergency signal is being output from the emergency output unit, it is preferable that the drive control unit operates the door to open so that at least a part of the entrance opens.

[0013] Regarding the above automatic door device, it includes a detection unit that detects an external force for moving the door in the opening direction. When the detection unit detects the external force when the emergency signal is being output from the emergency output unit, it is preferable that the drive control unit operates the door to open.

[0014] Regarding the above automatic door device, it is preferable to include a notification unit that notifies when the determination unit determines that the forced unlocking switch is abnormal. A control method for an automatic door device that solves the above problems is a control method for an automatic door device including an electric lock that locks a door provided at an entrance of a private room and drives it to open and close, and a forced unlocking switch that is provided outside the private room and unlocks the electric lock when operated, the method including a determination step of determining whether the forced unlocking switch is abnormal, and an invalidation step of invalidating the locking of the electric lock when it is determined that the forced unlocking switch is abnormal.

[0015] According to the above method, the abnormality of the forced unlocking switch is grasped, and when the forced unlocking switch is abnormal, the locking of the electric lock is invalidated. Therefore, even if an abnormality occurs in the forced unlocking switch, the electric lock is not locked, so the door can be opened from the outside in an emergency.

[0016] The control program of the automatic door device for solving the above problems is a control program of an automatic door device including an electric lock that locks a door provided at the entrance of a private room and drives it to open and close, and a forced unlocking switch that is provided outside the private room and unlocks the electric lock when operated. The computer executes a determination step of determining whether or not the forced unlocking switch is abnormal, and an invalidation step of invalidating the locking of the electric lock when it is determined that the forced unlocking switch is abnormal.

[0017] According to the above program, the abnormality of the forced unlocking switch is grasped, and when the forced unlocking switch is abnormal, the locking of the electric lock is invalidated. Therefore, even if an abnormality occurs in the forced unlocking switch, the electric lock is not locked, so the door can be opened from the outside in an emergency.

Effect of the Invention

[0018] According to the present invention, even if an abnormality occurs in the forced unlocking switch, the door can be opened from the outside in an emergency.

Mode for Carrying Out the Invention

[0020] Hereinafter, an embodiment of an automatic door device will be described with reference to FIGS. 1 to 4. Note that the automatic door device is installed in a multifunctional toilet.

[0021] As shown in FIG. 1, the multifunctional toilet 1 is a private room having one entrance / exit 2, and a toilet 3 is installed in a wide space so that a person with a disability or a person with children can use it easily. An automatic door device 5 for opening and closing the door 4 is installed at the entrance / exit 2. The door 4 is a sliding door that opens and closes the entrance / exit 2. Note that the multifunctional toilet 1 corresponds to a room. The entrance / exit 2 corresponds to an opening. The door 4 corresponds to a door leaf.

[0022] An outer door operation unit 30 for operating the opening and closing of the door 4 is installed on the outer wall of the multifunctional toilet 1. An inner door operation unit 40 for operating the opening and closing of the door 4 is also installed on the inner wall of the multifunctional toilet 1. An object detection sensor 12 for detecting a person or an object passing outside the entrance / exit 2 is installed on the blind outer side of the entrance / exit 2. The object detection sensor 12 detects a person or an object existing in a detection area A which is outside the entrance / exit 2 and within a predetermined range from the entrance / exit 2. An auxiliary sensor 13 for detecting a person standing still inside the entrance / exit 2 is installed on the inner wall of the entrance / exit 2. An occupancy sensor 15 for detecting a user inside the private room is installed on the ceiling. An emergency switch 16 is installed on the wall near the toilet 3. The emergency switch 16 is a switch that is operated when the user is in poor health or the like. When the emergency switch 16 is operated, it outputs an emergency signal. Note that the emergency switch 16 corresponds to an emergency output unit. Also, the outer door operation unit 30 corresponds to an outer operation unit.

[0023] The outer door operation unit 30 and the inner door operation unit 40 have substantially the same configuration. As shown in FIG. 2, the outer door operation unit 30 and the inner door operation unit 40 are provided with contact switches. The contact switch outputs an opening / closing instruction to open and close the door 4 by a contact operation of pressing a button switch. An outer opening switch 31 (inner opening switch 41) is installed above the outer door operation unit 30 and the inner door operation unit 40. On the surfaces of the outer opening switch 31 and the inner opening switch 41, "Open, ←→, OPEN" are described. The outer opening switch 31 and the inner opening switch 41 output an opening instruction for the door 4 when the button switch is pressed by the user. An outer closing switch 32 (inner closing switch 42) is installed below the outer door operation unit 30 and the inner door operation unit 40. On the surfaces of the outer closing switch 32 and the inner closing switch 42, "Close, →←, CLOSE" are described. The outer closing switch 32 and the inner closing switch 42 output a closing instruction for the door 4 when the button switch is pressed by the user. The outer opening switch 31, the inner opening switch 41, the outer closing switch 32, and the inner closing switch 42 perform lighting and blinking by built-in LEDs to guide the user's operation. Also, an outer speaker 35 (inner speaker 45) is provided between the outer opening switch 31 (inner opening switch 41) and the outer closing switch 32 (inner closing switch 42). Note that the outer opening switch 31, the inner opening switch 41, the outer closing switch 32, and the inner closing switch 42 may be switches such as touch sensors, not limited to button switches. The outer opening switch 31 corresponds to the outer opening operation unit.

[0024] The outer door operation unit 30 is provided with a forced unlocking switch 36. The forced unlocking switch 36 is a cylinder lock that outputs a forced unlocking signal when a key is inserted and turned. The forced unlocking switch 36 is a switch for the administrator of the multifunctional toilet 1 or the like to operate from the outside to unlock the door 4 when the user of the multifunctional toilet 1 cannot open the electric lock 14 of the door 4 from the inside. The forced unlocking switch 36 includes a first contact connected normally and a second contact connected during forced unlocking, and a state in which a signal is output from either of them is normal, and a state in which no signal is output is abnormal. Note that the forced unlocking switch 36 may perform an abnormality determination by itself and output it to the operation controller 20.

[0025] Next, with reference to FIG. 3, the electrical configuration of the automatic door device 5 will be described. The automatic door device 5 includes a door engine 11 that drives the door 4, an auxiliary sensor 13, an electric lock 14, a door controller 10 to which these devices are connected, an object detection sensor 12, and a presence sensor 15. The automatic door device 5 includes an operation controller 20 to which the outer door operation unit 30 and the inner door operation unit 40 are connected. The door controller 10, the operation controller 20, the object detection sensor 12, and the presence sensor 15 are connected to the CAN 50. When the auxiliary sensor 13 detects, it transmits a detection signal to the door controller 10. When the object detection sensor 12 and the presence sensor 15 detect, they transmit a detection signal to the door controller 10 and the operation controller 20 via the CAN 50. The door controller 10 drives and controls the door engine 11 according to the detection results of the object detection sensor 12, the auxiliary sensor 13, and the presence sensor 15.

[0026] The door controller 10 includes an arithmetic unit, a communication interface unit, a volatile memory unit, and a non-volatile memory unit respectively. The arithmetic unit is a computer processor, and controls the door engine 11 according to a control program stored in the non-volatile memory unit (memory medium). The arithmetic unit may implement at least a part of the processing it executes by circuitry such as an ASIC. The control program may be executed by one computer processor or by a plurality of computer processors. The door controller 10 may be configured as one or more processors that execute various processes according to a computer program (software). The processes executed by the door controller 10, that is, the processor, include a control method of the door controller 10. Note that the door controller 10 may be configured as one or more dedicated hardware circuits such as application specific integrated circuits (ASICs) that execute at least a part of various processes, or circuitry including combinations thereof. The processor includes a CPU and memories such as a RAM and a ROM. The memory stores program codes or instructions configured to cause the CPU to execute processing. The memory, that is, the computer-readable medium, includes any available medium accessible by a general-purpose or dedicated computer.

[0027] The operation controller 20 includes an arithmetic unit, a communication interface unit, a volatile memory unit, and a non-volatile memory unit respectively. The arithmetic unit is a computer processor, and controls the outer door operation unit 30 and the inner door operation unit 40 according to a control program stored in the non-volatile memory unit (storage medium). The arithmetic unit may implement at least a part of the processing it executes by circuitry such as an ASIC. The control program may be executed by one computer processor or by a plurality of computer processors. The operation controller 20 may be configured as one or more processors that execute various processes according to a computer program (software). The processes executed by the operation controller 20, that is, the processor, include a control method of the operation controller 20. The control method of the operation controller 20 includes a determination step and a disabling step described later. Note that the operation controller 20 may be configured as one or more dedicated hardware circuits such as an application specific integrated circuit (ASIC) that execute at least a part of various processes, or circuitry including a combination thereof. The processor includes a CPU and memories such as a RAM and a ROM. The memory stores program codes or instructions configured to cause the CPU to execute processing. The memory, that is, the computer-readable medium, includes any available medium accessible by a general-purpose or dedicated computer. The program stored in the computer-readable medium includes the control program of the operation controller 20. The control program of the operation controller 20 causes the computer to execute a determination step and a disabling step.

[0028] The operation controller 20 includes an operation control unit 21, a storage unit 22, and a determination unit 23. The storage unit 22 stores the abnormal determination conditions of the forced unlocking switch 36 and the voice data of operation guidance and caution messages according to each situation. The determination unit 23 determines whether the forced unlocking switch 36 is abnormal. When an opening instruction is received from the outer opening switch 31, the determination unit 23 determines whether the forced unlocking switch 36 is abnormal, and determines it as abnormal when no signal can be obtained from the forced unlocking switch 36. When the determination unit 23 determines that the forced unlocking switch 36 is abnormal, it outputs a forced unlocking switch abnormal signal. When the determination unit 23 determines that the forced unlocking switch 36 is abnormal, the outer speaker 35 notifies that the forced unlocking switch 36 is abnormal. The outer speaker 35 functions as a notification unit. When there is an emergency signal, the determination unit 23 determines whether the operation on the outer door operation unit 30 is a specific operation. When the determination unit 23 determines that it is a specific operation, the drive control unit 10A opens the door 4. The operation control unit 21 provides operation guidance by outputting voice from the outer speaker 35 and the inner speaker 45. The operation control unit 21 provides operation guidance when the object detection sensor 12 is in a detection state.

[0029] When the outer opening switch 31 detects a pressing operation, it outputs an outer opening instruction to the operation controller 20. When the outer closing switch 32 detects a pressing operation, it outputs an outer closing instruction to the operation controller 20. The operation controller 20 outputs the outer opening and closing instructions of the outer opening switch 31 and the outer closing switch 32 to the CAN 50.

[0030] When the inner opening switch 41 detects a pressing operation, it outputs an inner opening instruction to the operation controller 20. When the inner closing switch 42 detects a pressing operation, it outputs an inner closing instruction to the operation controller 20. The operation controller 20 outputs the inner opening and closing instructions of the inner opening switch 41 and the inner closing switch 42 to the CAN 50.

[0031] The door controller 10 includes a drive control unit 10A that drives and controls a door engine 11, and an electric lock control unit 10B. The drive control unit 10A controls the opening and closing of the door engine 11 based on opening and closing instructions from an outer door operation unit 30 and an inner door operation unit 40.

[0032] The electric lock control unit 10B drives and controls a drive unit (not shown) to lock and unlock the electric lock 14. When the determination unit 23 determines that the forced unlocking switch 36 is abnormal, if the electric lock control unit 10B has locked the electric lock 14, the electric lock control unit 10B unlocks the electric lock 14 and does not lock it again after unlocking. Also, when the determination unit 23 determines that the forced unlocking switch 36 is abnormal, if the electric lock control unit 10B has unlocked the electric lock 14, the electric lock control unit 10B continues to maintain the electric lock 14 in the unlocked state hereafter. Not locking the locked electric lock 14 again and maintaining the unlocked electric lock 14 in the unlocked state even when the locking condition is satisfied is referred to as "invalidating the locking of the electric lock".

[0033] When the determination unit 23 determines that the forced unlocking switch 36 is abnormal, the drive control unit 10A performs a pressing operation to continuously drive the door 4 in the closing direction when the door 4 driven in the closing direction is at the fully closed position. When the forced unlocking switch 36 is abnormal, when an inward opening instruction is received from the inner door operation unit 40, the drive control unit 10A stops the pressing operation of the door 4 in the closing direction and opens the door 4. When the determination unit 23 determines that the forced unlocking switch 36 is abnormal, when a distress signal is output from the distress switch 16, the drive control unit 10A reduces the pressing force to continuously drive the door 4 in the closing direction. When the detection unit 11A detects an external force while the distress signal is being output from the distress switch 16, the drive control unit 10A opens the door 4. Or, when the determination unit 23 determines that the forced unlocking switch 36 is abnormal, when a distress signal is output from the distress switch 16, the drive control unit 10A opens the door 4 so that at least a part of the entrance / exit 2 opens.

[0034] Next, with reference to FIG. 4, the processing procedure of the automatic door device 5 will be described. When the multifunctional toilet 1 is not in use, the automatic door device 5 waits with the door 4 fully closed. Then, when the outer open switch 31 is operated, the automatic door device 5 drives the door engine 11 to open the door 4. Note that when the multifunctional toilet 1 is not in use, the automatic door device 5 may wait with the door 4 fully open.

[0035] As shown in FIG. 4, the automatic door device 5 determines whether there is an operation of the inner close switch 42 (step S11). That is, when the inner close switch 42 is operated by the user, it outputs an inner close instruction to the operation controller 20. The operation controller 20 outputs an inner close instruction to the door controller 10. When the operation control unit 21 determines that there is no operation of the inner close switch 42 (step S11: NO), it waits until the inner close switch 42 is operated.

[0036] On the other hand, when the operation control unit 21 determines that there is an operation of the inner close switch 42 (step S11: YES), it closes the door 4 (step S12) and locks the electric lock 14 (step S13). That is, the operation control unit 21 outputs an inner close instruction to the door controller 10 via the CAN 50. The drive control unit 10A drives and controls the door engine 11 based on the inner close instruction to close the door 4. When the door 4 is fully closed, the electric lock control unit 10B drives the drive unit of the electric lock 14 in the locking direction to lock the door 4.

[0037] Subsequently, the automatic door device 5 determines whether the forced unlocking switch 36 is abnormal (step S14). That is, the determination unit 23 determines whether the forced unlocking switch 36 is abnormal. Step S14 corresponds to a determination step. When the determination unit 23 determines that the forced unlocking switch 36 is not abnormal (step S14: NO), it proceeds to step S21. That is, the automatic door device 5 maintains the state in which the door 4 is closed and the electric lock 14 is locked while the user is using it.

[0038] Then, the automatic door device 5 determines whether or not there is an operation of the inner opening switch 41 (step S21). That is, when the inner opening switch 41 is operated by the user, it outputs an inner opening instruction to the operation controller 20. The operation controller 20 outputs the inner opening instruction to the door controller 10. When the operation control unit 21 determines that there is no operation of the inner opening switch 41 (step S21: NO), it waits until the inner opening switch 41 is operated.

[0039] On the other hand, when the operation control unit 21 determines that there is an operation of the inner opening switch 41 (step S21: YES), it proceeds to step S20. The drive control unit 10A drives and controls the door engine 11 based on the inner opening instruction to open the door 4 (step S20).

[0040] On the other hand, when the determination unit 23 determines that the forced unlocking switch 36 is abnormal (step S14: YES), the automatic door device 5 unlocks the electric lock 14 (step S15). That is, the electric lock control unit 10B drives the drive unit of the electric lock 14 in the unlocking direction to unlock it. Thus, the electric lock 14 is made ineffective. In addition, the operation control unit 21 causes the outer speaker 35 to notify that the forced unlocking switch 36 is abnormal. Step S15 corresponds to an invalid step.

[0041] Then, the automatic door device 5 drives and presses in the closing direction (step S16). That is, when the electric lock control unit 10B invalidates the electric lock 14, the drive control unit 10A causes the door 4 to continue to be driven in the closing direction at the fully closed position of the door 4 to perform a pressing operation. The drive control unit 10A drives and presses the door engine 11 in the closing direction so that the door 4 does not open even if the electric lock 14 is unlocked.

[0042] Subsequently, the automatic door device 5 determines whether there is an emergency signal (step S17). That is, when the emergency switch 16 is operated by the user, it outputs an emergency signal to the CAN 50. The door controller 10 and the operation controller 20 acquire the emergency signal via the CAN 50. Note that the door controller 10 and the operation controller 20 may also consider that there is an output of the emergency signal even when a predetermined time has elapsed after the door 4 is closed in the occupied state. And when the door controller 10 and the operation controller 20 do not acquire the emergency signal (step S17: NO), the process proceeds to step S21.

[0043] On the other hand, when the operation controller 20 acquires the emergency signal (step S17: YES), it outputs voice guidance (step S18). That is, the operation control unit 21 outputs from the outer speaker 35 and the inner speaker 45 that the emergency switch 16 has been pressed.

[0044] Subsequently, the automatic door device 5 determines whether there is a specific operation (step S19). That is, the determination unit 23 determines whether the operation on the outer door operation unit 30 is a specific operation. And when the determination unit 23 determines that the operation on the outer door operation unit 30 is not a specific operation (step S19: NO), the process proceeds to step S18.

[0045] On the other hand, when the determination unit 23 determines that the operation on the outer door operation unit 30 is a specific operation (step S19: YES), it opens the door 4 (step S20). That is, the drive control unit 10A drives and controls the door engine 11 based on the specific operation to open the door 4. When there is an emergency signal, the drive control unit 10A may open the door 4 by at least a part of the width of the entrance 2 or by half of the width of the entrance 2 so that one can peek inside. Note that when the inner open switch 41 of the inner door operation unit 40 is operated, the process proceeds to step S20.

[0046] In addition, when the door controller 10 acquires an emergency signal, it may determine whether there is a force in the opening direction on the door 4, and if it determines that there is a force in the opening direction, the door 4 may be opened. The force in the opening direction on the door 4 is acquired from the detection unit 11A. That is, the drive control unit 10A drives and controls the door engine 11 based on the fact that the door 4 is about to be opened, and opens the door 4.

[0047] Next, the effects of this embodiment will be described. (1) The determination unit 23 grasps the abnormality of the forced unlocking switch 36, and when the forced unlocking switch 36 is abnormal, the electric lock control unit 10B invalidates the locking of the electric lock 14. Therefore, even if an abnormality occurs in the forced unlocking switch 36, the electric lock 14 is not locked, so the door 4 can be opened from the outside in an emergency.

[0048] (2) If the forced unlocking switch 36 is abnormal, the forced unlocking switch 36 cannot unlock the electric lock 14. Therefore, after the electric lock control unit 10B unlocks the locked electric lock 14 and does not lock it again, it is invalidated. For this reason, when the forced unlocking switch 36 is abnormal, the electric lock 14 is in the unlocked state, and the door 4 can be opened from the outside in an emergency.

[0049] (3) If the forced unlocking switch 36 is abnormal, the forced unlocking switch 36 cannot unlock the electric lock 14. Therefore, the electric lock control unit 10B invalidates it by maintaining the electric lock 14 in the unlocked state. For this reason, when the forced unlocking switch 36 is abnormal, the electric lock 14 is in the unlocked state, and the door 4 can be opened from the outside in an emergency.

[0050] (4) When an opening instruction is given from the outer door operation unit 30, the door 4 is closed and locked. Therefore, it is possible to determine whether the forced unlocking switch 36 is abnormal before the locking operation, and be prepared for the locking operation.

[0051] (5) When the forced unlocking switch 36 is abnormal, since the door 4 is pressed in the closing direction when the door 4 is in the closed state, the door 4 can be maintained in the closed state even if the electric lock 14 is not locked.

[0052] (6) When an emergency signal is output from the emergency switch 16 provided inside the private room, it is highly likely that the door 4 cannot be opened from the inside of the private room. Therefore, by detecting the load in the opening direction of the door 4 and operating the door 4 to open, a person other than the user of the private room can check the inside of the private room.

[0053] (7) By notifying that the forced unlocking switch 36 is abnormal by the outer speaker 35, the fact that the forced unlocking switch 36 is abnormal can be recognized by the user or administrator of the private room.

[0054] (Other embodiments) The above embodiment can be implemented with the following modifications. The above embodiment and the following modification examples can be implemented in combination with each other within a technically non - conflicting range.

[0055] · In the above embodiment, after locking the electric lock 14 in step S12, the determination unit 23 determines whether the forced unlocking switch 36 is abnormal in step S13. However, the determination unit 23 may determine whether the forced unlocking switch 36 is abnormal before locking the electric lock 14. In this way, the electric lock 14 can be maintained in the unlocked state and made invalid without locking the electric lock 14.

[0056] · In the above embodiment, it is notified from the outer speaker 35 that the forced unlocking switch 36 is abnormal. However, a notification unit such as a display device other than the outer speaker 35 may be provided for notification. Also, the notification that the forced unlocking switch 36 is abnormal may be omitted.

[0057] · In the above embodiment, when the detection unit 11A detects an external force while an emergency signal is being output from the emergency switch 16, the drive control unit 10A causes the door 4 to open. However, the detection unit 11A that detects an external force for moving the door 4 in the opening direction may be omitted, and the opening operation of the door 4 due to the detection of an external force may not be performed.

[0058] · In the above embodiment, when the determination unit 23 determines that the forced unlocking switch 36 is abnormal, when an emergency signal is being output from the emergency switch 16, the drive control unit 10A may cause the door 4 to open at least partially regardless of a specific operation. According to such a configuration, when an emergency signal is being output from the emergency switch 16 provided inside the private room, there is a high possibility that the door 4 cannot be opened from the inside of the private room. Therefore, by causing the door 4 to open so that at least a part of the entrance / exit 2 opens even without an opening instruction from the operation unit, a person other than the user of the private room can check the inside of the private room.

[0059] · In the above embodiment, when the determination unit 23 determines that the forced unlocking switch 36 is abnormal, when an emergency signal is being output from the emergency switch 16, the drive control unit 10A may cause the door 4 to open when there is an outward opening instruction from the outer door operation unit 30.

[0060] · In the above embodiment, when the determination unit 23 determines that the forced unlocking switch 36 is abnormal, when an emergency signal is being output from the emergency switch 16, the drive control unit 10A may reduce the pressing force for continuously driving the door 4 in the closing direction to be less than that of a normal pressing operation. According to such a configuration, when an emergency signal is being output from the emergency switch 16 provided inside the private room, there is a high possibility that the door 4 cannot be opened from the inside of the private room, and there is a possibility that a person other than the user of the private room may open the door 4. Therefore, by reducing the pressing force for continuously driving the door 4 in the closing direction to be less than that of a normal pressing operation, it is possible to make it easier for a person other than the user of the private room to open the door 4.

[0061] · In the above-described embodiment, when the determination unit 23 determines that the forced unlocking switch 36 is abnormal, the door 4 is pressed in the closing direction when the door 4 is in the fully closed state. However, when it is determined that the forced unlocking switch 36 is abnormal, the door 4 may not be pressed in the closing direction when the door 4 is in the fully closed state.

[0062] · In the above-described embodiment, after the electric lock 14 is locked, the determination unit 23 determines whether or not the forced unlocking switch 36 is abnormal. However, the determination unit 23 may determine whether or not the forced unlocking switch 36 is abnormal when there is an outward opening instruction from the outer door operation unit 30. When the determination unit 23 determines that it is abnormal when there is an outward opening instruction from the outer door operation unit 30, the electric lock 14 is not locked thereafter. According to such a configuration, since the door 4 is closed and locked after there is an opening instruction from the outer door operation unit 30, it is possible to determine whether or not the forced unlocking switch 36 is abnormal before the locking operation and be prepared for the locking operation.

[0063] · In the above-described embodiment, the door operation unit has separate open and close switches, but it may be a door operation unit having a single shared switch for opening and closing. The shared switch outputs an operation signal when operated. When the door 4 is in the open state and the shared switch is operated, the operation controller 20 processes the operation signal as a close signal, and when the door 4 is in the closed state and the shared switch is operated, the operation signal is processed as an open signal.

[0064] · In the above-described embodiment, those constituted by a plurality of objects may integrate the plurality of objects, and conversely, those constituted by a single object may be divided into a plurality of objects. Regardless of whether they are integrated or not, they may be configured to achieve the object of the invention.

[0065] ·In the above-described embodiment, in the case where a plurality of functions are provided in a distributed manner, some or all of the plurality of functions may be provided in an aggregated manner. Conversely, in the case where a plurality of functions are provided in an aggregated manner, some or all of the plurality of functions may be provided in a distributed manner. Regardless of whether the functions are aggregated or distributed, it is only necessary that the configuration be such that the object of the invention can be achieved.
