JP 2016-084616 A

However, in the automatic door system described in Patent Document 1, if an abnormality occurs in the forced unlocking switch, it becomes impossible to forcibly unlock the locking mechanism from the forced unlocking switch, making it cumbersome to open the door in an emergency. For this reason, there is a demand for an automatic door system that allows the door to be opened from the outside in an emergency even if an abnormality occurs in the forced unlocking switch.

The automatic door device that solves the above problem includes a door that is installed at the entrance of a private room and is automatically opened and closed, an electric lock that locks the door, an electric lock control unit that controls the locking and unlocking of the electric lock, a forced unlock switch that is installed outside the private room and that outputs an unlocking signal to the electric lock control unit when operated to unlock the electric lock, and a judgment unit that judges whether the forced unlock switch is abnormal. When the judgment unit judges that the forced unlock switch is abnormal, the electric lock control unit disables the locking of the electric lock.

According to the above configuration, the judgment unit detects an abnormality in the forced unlocking switch, and if the forced unlocking switch is abnormal, the electric lock control unit disables 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.

In the above-mentioned automatic door device, when the determination unit determines that the forced unlock switch is abnormal, if the electric lock control unit has locked the electric lock, it is preferable that the electric lock control unit unlocks the electric lock and does not lock it again after unlocking.

For the above-mentioned automatic door device, when the determination unit determines that the forced unlock switch is abnormal, if the electric lock control unit has unlocked the electric lock, it is preferable that the electric lock control unit continue to unlock the electric lock.

The above-mentioned automatic door system preferably includes a drive control unit that controls the opening and closing drive of the door, an outside opening operation unit that is provided outside the private room and outputs an instruction to open or close the door to the drive control unit, and the determination unit determines whether or not the forced unlocking switch is abnormal when an open instruction is received from the outside opening operation unit.

The above-mentioned automatic door device is preferably provided with a drive control unit that controls the opening and closing drive of the door, and when the determination unit determines that the forced unlocking switch is abnormal, a pressing operation is performed to continue to drive the door in the closing direction when the door is in the fully closed position.

The above-mentioned automatic door device is provided with an emergency output unit that is provided inside the private room and outputs an emergency signal when operated by a user of the private room, and when the determination unit determines that the forced unlocking switch is abnormal and the emergency signal is being output from the emergency output unit, it is preferable that the drive control unit reduces the pressing force that continues to drive the door in the closing direction to less than the normal pressing force.

The above-mentioned automatic door device is provided with 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 when operated by a user of the private room, and when the determination unit determines that the forced unlocking switch is abnormal and the emergency signal is output from the emergency output unit, it is preferable that the drive control unit opens the door so that at least a part of the entrance is opened.

The above-mentioned automatic door device preferably includes a detection unit that detects an external force that moves the door in the opening direction, and the drive control unit preferably opens the door when the detection unit detects the external force while the emergency output unit is outputting the emergency signal.

In the above automatic door system, it is preferable that the determination unit further comprises a notification unit that issues a notification when it determines that the forced unlocking switch is abnormal.
A control method for an automatic door system that solves the above-mentioned problems is a control method for an automatic door system equipped with an electric lock that is provided at the entrance to a private room and locks a door that is driven to open and close, and a forced unlock switch that is provided outside the private room and is operated to unlock the electric lock, and includes a determination step of determining whether or not the forced unlock switch is abnormal, and an invalidation step of invalidating the locking of the electric lock when it is determined that the forced unlock switch is abnormal.

According to the above method, an abnormality in the forced unlocking switch is detected, and the electric lock is disabled if the forced unlocking switch is abnormal. 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.

The control program for an automatic door system that solves the above problem is a control program for an automatic door system that includes an electric lock that is installed at the entrance to a private room and locks a door that opens and closes, and a forced unlocking switch that is installed outside the private room and is operated to unlock the electric lock, and the computer executes a determination step for determining whether the forced unlocking switch is abnormal, and an invalidation step for invalidating the locking of the electric lock when it is determined that the forced unlocking switch is abnormal.

According to the above program, the system detects an abnormality in the forced unlocking switch and disables the electric lock if the forced unlocking switch is abnormal. 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.

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.

1 is a plan view showing the configuration of a multi-function toilet in which an embodiment of an automatic door device is installed. FIG. 2 is a front view showing the configuration of an operation unit of the automatic door system according to the embodiment. FIG. 2 is a block diagram showing the electrical configuration of the automatic door system according to the embodiment. 4 is a flowchart showing the operation of the automatic door system according to the embodiment.

Below, one embodiment of an automatic door system will be described with reference to Figures 1 to 4. The automatic door system is installed in a multi-purpose toilet.

As shown in FIG. 1, the multi-function toilet 1 is a private room with one entrance 2, and a toilet bowl 3 is installed in a large space to make it easy for people with disabilities and people with children to use. An automatic door device 5 that drives the door 4 to open and close is installed at the entrance 2. The door 4 is a sliding door that opens and closes the entrance 2. The multi-function toilet 1 corresponds to a room. The entrance 2 corresponds to an opening. The door 4 corresponds to a door.

An outer door operating unit 30 that operates the opening and closing of the door 4 is installed on the outer wall of the multi-function toilet 1. An inner door operating unit 40 that also operates the opening and closing of the door 4 is installed on the inner wall of the multi-function toilet 1. An object detection sensor 12 that detects people and objects passing outside the entrance/exit 2 is installed on the outside of the entrance/exit 2. The object detection sensor 12 detects people and objects that are present in a detection area A that is outside the entrance/exit 2 and is a predetermined range from the entrance/exit 2. An auxiliary sensor 13 that detects people standing inside the entrance/exit 2 is installed on the inner wall of the entrance/exit 2. An occupancy sensor 15 that detects users in 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 becomes unwell. When the emergency switch 16 is operated, it outputs an emergency signal. The emergency switch 16 corresponds to the emergency output unit. The outer door operating unit 30 corresponds to the external operating unit.

The outer door operation unit 30 and the inner door operation unit 40 have almost the same configuration. As shown in FIG. 2, the outer door operation unit 30 and the inner door operation unit 40 are equipped with a contact switch. The contact switch outputs an open/close command to open/close the door 4 by a contact operation of pressing a button switch. An outer opening switch 31 (inner opening switch 41) is provided near the upper part of the outer door operation unit 30 and the inner door operation unit 40. "Open, ←→, OPEN" is written on the surface of the outer opening switch 31 and the inner opening switch 41. The outer opening switch 31 and the inner opening switch 41 output an open command to the door 4 when the button switch is pressed by the user. An outer closing switch 32 (inner closing switch 42) is provided near the lower part of the outer door operation unit 30 and the inner door operation unit 40. "Close, →←, CLOSE" is written on the surface of the outer closing switch 32 and the inner closing switch 42. The outside close switch 32 and the inside close switch 42 output a command to close the door 4 when the button switch is pressed by the user. The outside open switch 31, the inside open switch 41, the outside close switch 32, and the inside close switch 42 light up or blink with built-in LEDs to guide the user's operation. In addition, an outside speaker 35 (an inside speaker 45) is provided between the outside open switch 31 (an inside open switch 41) and the outside close switch 32 (an inside close switch 42). The outside open switch 31, the inside open switch 41, the outside close switch 32, and the inside close switch 42 are not limited to button switches, and may be switches such as touch sensors. The outside open switch 31 corresponds to the outside open operation unit.

The outer door operation unit 30 is equipped 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 that the manager of the multi-function toilet 1 operates from the outside to unlock the door 4 when a user of the multi-function toilet 1 is unable to open the electric lock 14 of the door 4 from the inside. The forced unlocking switch 36 has a first contact that is normally connected and a second contact that is connected during forced unlocking. A normal state is when a signal is output from either of the contacts, and an abnormal state is when no signal is output. The forced unlocking switch 36 may be configured to determine an abnormality on its own and output the result to the operation controller 20.

Next, the electrical configuration of the automatic door system 5 will be described with reference to FIG.
The automatic door system 5 includes a door engine 11 for driving 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 occupancy sensor 15. The automatic door system 5 includes an operation controller 20 to which an outer door operation unit 30 and an inner door operation unit 40 are connected. The door controller 10, the operation controller 20, the object detection sensor 12, and the occupancy sensor 15 are connected to a CAN 50. The auxiliary sensor 13 transmits a detection signal to the door controller 10 upon detection. The object detection sensor 12 and the occupancy sensor 15 transmit a detection signal to the door controller 10 and the operation controller 20 via the CAN 50 upon detection. The door controller 10 controls the drive of the door engine 11 according to the detection results of the object detection sensor 12, the auxiliary sensor 13, and the occupancy sensor 15.

The door controller 10 includes a calculation unit, a communication interface unit, a volatile storage unit, and a non-volatile storage unit. The calculation unit is a computer processor, and controls the door engine 11 according to a control program stored in the non-volatile storage unit (storage medium). The calculation unit may realize at least a part of the processing that it executes by a circuit such as an ASIC. The control program may be executed by one computer processor or by multiple computer processors. The door controller 10 may be configured as one or more processors that execute various processing according to a computer program (software). The processing executed by the door controller 10, i.e., the processor, includes a control method for the door controller 10. The door controller 10 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 the various processing, or a circuit that includes a combination of these. The processor includes a CPU and memories such as a RAM and a ROM. The memory stores program codes or instructions that are configured to cause the CPU to execute the processing. Memory, or computer-readable media, includes any available media that can be accessed by a general purpose or special purpose computer.

The operation controller 20 includes a calculation unit, a communication interface unit, a volatile storage unit, and a non-volatile storage unit. The calculation 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 storage unit (storage medium). The calculation unit may realize at least a part of the processing it executes by a circuit such as an ASIC. The control program may be executed by one computer processor, or may be executed by multiple computer processors. The operation controller 20 may be configured as one or more processors that execute various processing according to a computer program (software). The processing executed by the operation controller 20, i.e., the processor, includes a control method for the operation controller 20. The control method for the operation controller 20 includes a determination step and an invalid step, which will be described later. 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 the various processing, or a circuit including a combination thereof. The processor includes a CPU and memory such as RAM and ROM. The memory stores program code or instructions configured to cause the CPU to execute processes. The memory, i.e., computer-readable medium, includes any available medium accessible by a general-purpose or special-purpose computer. The program stored in the computer-readable medium includes a control program for the operation controller 20. The control program for the operation controller 20 causes the computer to execute a determination step and an invalidation step.

The operation controller 20 includes an operation control unit 21, a memory unit 22, and a judgment unit 23. The memory unit 22 stores the conditions for judging an abnormality of the forced unlocking switch 36, and voice data of operation guidance and attention-calling guidance messages according to each situation. The judgment unit 23 judges whether the forced unlocking switch 36 is abnormal. The judgment unit 23 judges whether the forced unlocking switch 36 is abnormal when an open command is received from the outer opening switch 31, and judges an abnormality when no signal is obtained from the forced unlocking switch 36. When the judgment unit 23 judges that the forced unlocking switch 36 is abnormal, it outputs a forced unlocking switch abnormality signal. When the judgment unit 23 judges that the forced unlocking switch 36 is abnormal, it notifies the outer speaker 35 that the forced unlocking switch 36 is abnormal. The outer speaker 35 functions as a notification unit. When there is an emergency signal, the judgment unit 23 judges whether the operation on the outer door operation unit 30 is a specific operation. When the determination unit 23 determines that the operation is a specific operation, the drive control unit 10A opens the door 4. The operation control unit 21 provides operation guidance for the operation switch by outputting sound from the outer speaker 35 and the inner speaker 45. The operation control unit 21 provides operation guidance when the object detection sensor 12 enters a detection state.

When the outside open switch 31 detects a push operation, it outputs an outside open command to the operation controller 20. When the outside close switch 32 detects a push operation, it outputs an outside close command to the operation controller 20. The operation controller 20 outputs the outside open/close commands of the outside open switch 31 and the outside close switch 32 to the CAN 50.

When the inside open switch 41 detects a push operation, it outputs an inside open command to the operation controller 20. When the inside close switch 42 detects a push operation, it outputs an inside close command to the operation controller 20. The operation controller 20 outputs the inside open/close commands of the inside open switch 41 and the inside close switch 42 to the CAN 50.

The door controller 10 includes a drive control unit 10A that drives and controls the 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 the outer door operation unit 30 and the inner door operation unit 40.

The electric lock control unit 10B drives and controls a drive unit (not shown) to lock and unlock the electric lock 14. When the judgment unit 23 judges 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 after unlocking. Also, when the judgment unit 23 judges 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 an unlocked state thereafter. Unlocking a locked electric lock 14 and not locking it thereafter, and maintaining an unlocked electric lock 14 in an unlocked state even if the locking conditions are met, are referred to as "invalidating the locking of the electric lock."

When the determination unit 23 determines that the forced unlocking switch 36 is abnormal, the drive control unit 10A performs a pressing operation to continue driving the door 4 in the closing direction when the door 4 driven in the closing direction is in the fully closed position. When the forced unlocking switch 36 is abnormal, the drive control unit 10A stops the pressing operation of the door 4 in the closing direction and opens the door 4 when an inward opening command is received from the inner door operation unit 40. When the determination unit 23 determines that the forced unlocking switch 36 is abnormal, the drive control unit 10A reduces the pressing force that continues to drive the door 4 in the closing direction when an emergency signal is output from the emergency switch 16. When the detection unit 11A detects an external force while an emergency signal is output from the emergency switch 16, the drive control unit 10A opens the door 4. Alternatively, when the determination unit 23 determines that the forced unlocking switch 36 is abnormal, the drive control unit 10A opens the door 4 so that at least a part of the entrance 2 is opened when an emergency signal is output from the emergency switch 16.

Next, the processing procedure of the automatic door device 5 will be described with reference to FIG. 4. When the multi-function toilet 1 is not in use, the automatic door device 5 waits with the door 4 fully closed. When the outward opening switch 31 is operated, the automatic door device 5 drives the door engine 11 to open the door 4. Note that when the multi-function toilet 1 is not in use, the automatic door device 5 may wait with the door 4 fully open.

As shown in FIG. 4, the automatic door device 5 determines whether the inside close switch 42 has been operated (step S11). That is, when the inside close switch 42 is operated by a user, it outputs an inside close command to the operation controller 20. The operation controller 20 outputs an inside close command to the door controller 10. If the operation control unit 21 determines that the inside close switch 42 has not been operated (step S11: NO), it waits until the inside close switch 42 is operated.

On the other hand, if the operation control unit 21 determines that the inside close switch 42 has been operated (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 inside close command to the door controller 10 via the CAN 50. The drive control unit 10A drives and controls the door engine 11 based on the inside close command to close the door 4. Then, when the door 4 is in a fully closed state, the electric lock control unit 10B drives the drive unit of the electric lock 14 in the locking direction to lock the door 4.

The automatic door device 5 then 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 the determination step. If the determination unit 23 determines that the forced unlocking switch 36 is not abnormal (step S14: NO), the process proceeds to step S21. That is, the automatic door device 5 keeps the door 4 closed and the electric lock 14 locked while the user is using the door.

Then, the automatic door device 5 judges whether the inside-opening switch 41 has been operated (step S21). That is, when the inside-opening switch 41 is operated by a user, it outputs an inside-opening command to the operation controller 20. The operation controller 20 outputs an inside-opening command to the door controller 10. If the operation control unit 21 judges that the inside-opening switch 41 has not been operated (step S21: NO), it waits until the inside-opening switch 41 is operated.

On the other hand, if the operation control unit 21 determines that the inward opening switch 41 has been operated (step S21: YES), the process proceeds to step S20. The drive control unit 10A controls the drive of the door engine 11 based on the inward opening command to open the door 4 (step S20).

On the other hand, if the judgment 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 disabled. In addition, the operation control unit 21 causes the outside speaker 35 to notify that the forced unlocking switch 36 is abnormal. Step S15 corresponds to the disable step.

Then, the automatic door device 5 is pushed in the closing direction (step S16). That is, when the electric lock control unit 10B disables the electric lock 14, the drive control unit 10A performs a pushing operation that continues to drive the door 4 in the closing direction when the door 4 is in the fully closed position. The drive control unit 10A pushes the door engine 11 in the closing direction to prevent the door 4 from opening even if the electric lock 14 is unlocked.

The automatic door device 5 then determines whether or not an emergency signal has been received (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. The door controller 10 and the operation controller 20 may also consider that an emergency signal has been output when a predetermined time has elapsed since the door 4 was closed while the user was present in the room. Then, if the door controller 10 and the operation controller 20 have not acquired an emergency signal (step S17: NO), the process proceeds to step S21.

On the other hand, if the operation controller 20 receives an 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.

The automatic door device 5 then determines whether or not a specific operation has been performed (step S19). That is, the determination unit 23 determines whether or not the operation performed on the outer door operation unit 30 is a specific operation. If the determination unit 23 determines that the operation performed on the outer door operation unit 30 is not a specific operation (step S19: NO), the process proceeds to step S18.

On the other hand, if 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 an emergency signal is received, the drive control unit 10A may open the door 4 by at least a part of the width of the entrance 2, or half the width of the entrance 2, so that the inside can be seen. Note that if the inner opening switch 41 of the inner door operation unit 40 is operated, the process proceeds to step S20.

When the door controller 10 receives an emergency signal, it may determine whether or not there is an opening force on the door 4, and may open the door 4 if it determines that there is an opening force. The opening force on the door 4 is obtained from the detection unit 11A. That is, the drive control unit 10A controls the drive of the door engine 11 to open the door 4 based on the fact that the door 4 is about to be opened.

Next, the effects of this embodiment will be described.
(1) The determination unit 23 detects an abnormality in the forced unlocking switch 36, and if the forced unlocking switch 36 is abnormal, the electric lock control unit 10B disables 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.

(2) If the forced unlocking switch 36 is abnormal, the forced unlocking switch 36 cannot unlock the electric lock 14, so the electric lock control unit 10B unlocks the locked electric lock 14 and then disables it by not locking it again. Therefore, when the forced unlocking switch 36 is abnormal, the electric lock 14 is unlocked, and the door 4 can be opened from the outside in an emergency.

(3) If the forced unlocking switch 36 is abnormal, the forced unlocking switch 36 cannot unlock the electric lock 14, so the electric lock control unit 10B disables the electric lock 14 by maintaining it in the unlocked state. Therefore, 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.

(4) Since the door 4 is closed and locked when an open command is received from the outer door operating unit 30, it is possible to prepare for the locking operation by determining whether or not the forced unlocking switch 36 is abnormal before the locking operation.

(5) If the forced unlock switch 36 is abnormal, the door 4 is pushed in the closing direction when the door 4 is closed, so that the door 4 can be kept closed even if the electric lock 14 is not locked.

(6) When an emergency signal is being output from the emergency switch 16 installed inside the private room, it is highly likely that the door 4 cannot be opened from inside the private room. Therefore, by detecting a load in the opening direction of the door 4 and opening the door 4, people other than the private room user can check the inside of the private room.

(7) By using the external speaker 35 to notify that the forced unlock switch 36 is abnormal, the user of the private room, the manager, etc. can be made aware that the forced unlock switch 36 is abnormal.

Other Embodiments
The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.

- In the above embodiment, after the electric lock 14 is locked in step S12, the judgment unit 23 judges whether or not the forced unlock switch 36 is abnormal in step S13. However, the judgment unit 23 may judge whether or not the forced unlock switch 36 is abnormal before the electric lock 14 is locked. In this way, the electric lock 14 can be kept in an unlocked state and disabled without being locked.

In the above embodiment, the external speaker 35 notifies the user that the forced unlocking switch 36 is abnormal. However, a notification unit such as a display device other than the external speaker 35 may be provided to notify the user. In addition, the notification that the forced unlocking switch 36 is abnormal may be omitted.

- In the above embodiment, if 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 opens the door 4. However, it is also possible to omit the detection unit 11A that detects an external force that moves the door 4 in the opening direction, and not open the door 4 when an external force is detected.

- In the above embodiment, if the determination unit 23 determines that the forced unlock switch 36 is abnormal, and an emergency signal is output from the emergency switch 16, the drive control unit 10A may operate to at least partially open the door 4 regardless of a specific operation. With this configuration, 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 inside the private room. Therefore, by operating the door 4 to open so that at least a portion of the entrance/exit 2 is open even without an open command from the operation unit, people other than the user of the private room can check the inside of the private room.

- In the above embodiment, when the determination unit 23 determines that the forced unlock switch 36 is abnormal, if an emergency signal is being output from the emergency switch 16, the drive control unit 10A may open the door 4 when an outward opening command is received from the outer door operating unit 30.

- In the above embodiment, if the determination unit 23 determines that the forced unlock switch 36 is abnormal, and an emergency signal is output from the emergency switch 16, the drive control unit 10A may reduce the pressing force that continues to drive the door 4 in the closing direction regardless of a specific operation, compared to the normal pressing action. With this configuration, 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 inside the private room, and there is a possibility that someone other than the private room user may open the door 4. Therefore, by reducing the pressing force that continues to drive the door 4 in the closing direction compared to the normal pressing action, it is possible to make it easier for people other than the private room user to open the door 4.

- In the above embodiment, if the determination unit 23 determines that the forced unlocking switch 36 is abnormal, the door 4 is pushed in the closing direction when the door 4 is in the fully closed state. However, if the determination unit 23 determines that the forced unlocking switch 36 is abnormal, the door 4 may not be pushed in the closing direction when the door 4 is in the fully closed state.

- In the above embodiment, the judgment unit 23 judges whether the forced unlock switch 36 is abnormal after the electric lock 14 is locked. However, the judgment unit 23 may judge whether the forced unlock switch 36 is abnormal when an outward open command is received from the outer door operation unit 30. If the judgment unit 23 judges that there is an abnormality when an outward open command is received from the outer door operation unit 30, the electric lock 14 is not locked thereafter. With this configuration, when an open command is received from the outer door operation unit 30, the door 4 is closed and locked afterwards. Therefore, it is possible to judge whether the forced unlock switch 36 is abnormal before the locking operation and prepare for the locking operation.

- In the above embodiment, the door operation unit has separate open and close switches, but the door operation unit may have a single shared switch for opening and closing. The shared switch outputs an operation signal when operated. When the door 4 is open and the shared switch is operated, the operation controller 20 processes the operation signal as a close signal, and when the door 4 is closed and the shared switch is operated, the operation signal is processed as an open signal.

- In the above embodiment, if something is made up of multiple objects, the multiple objects may be integrated, and conversely, if something is made up of a single object, it may be divided into multiple objects. Regardless of whether they are integrated or not, it is sufficient that the object of the invention can be achieved.
