[0010] The embodiments for carrying out the subject of the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are given the same reference numerals, and duplicated descriptions are appropriately simplified or omitted. Note that the subject of the present disclosure is not limited to the following embodiments, and any component of the embodiment may be modified or omitted within the scope of the gist of the present disclosure.

[0011] Embodiment 1 FIG. 1 is a configuration diagram of an elevator 1 according to the first embodiment.

[0012] The elevator 1 is applied to a building having a plurality of floors. A hoistway 2 is provided in the building. The hoistway 2 is a long space in the vertical direction that spans a plurality of floors. A landing 3 for the elevator 1 is provided on each floor. The landing 3 is a location adjacent to the hoistway 2. A landing entrance 4 is provided at the landing 3 on each floor. The landing entrance 4 is an opening that leads from the landing 3 to the hoistway 2. A landing door 5 is provided at each landing 3. The landing door 5 is an example of a door for the elevator 1. The landing door 5 includes a jamb 6 and a landing door panel 7. The jamb 6 is a frame that surrounds the landing entrance 4. The jamb 6 is an example of a door frame for the door of the elevator 1. The landing door panel 7 is disposed at the landing entrance 4. The landing door panel 7 is a device that opens and closes at the landing entrance 4 to separate the landing 3 and the elevator shaft 2. In this example, the landing door panel 7 opens and closes in the left-right direction. The landing door panel 7 is an example of a door panel of the door of the elevator 1.

[0013] The elevator 1 comprises a car 8 and a control panel 9.

[0014] The car 8 is a device that transports passengers and the like riding inside between multiple floors by traveling vertically through the elevator shaft 2. A car entrance 10 is provided in the car 8. The car entrance 10 is an opening that leads from the inside of the car 8 to the outside. The car 8 is equipped with a car door 11. The car door 11 is an example of a door of the elevator 1. The car door 11 is equipped with a sleeve wall 12, a car door panel 13, and a door device 14. The sleeve wall 12 forms a frame that surrounds the car entrance 10. The sleeve wall 12 is an example of a door frame of the door of the elevator 1. The car door panel 13 is disposed at the car entrance 10. The car door panel 13 is a device that opens and closes at the car entrance 10 to separate the inside and outside of the car 8. In this example, the car door panel 13 opens and closes in the left-right direction. The car door panel 13 is an example of a door panel of the door of the elevator 1. The door device 14 is a device that opens and closes the car door panel 13. In this example, the door device 14 is disposed above the car door panel 13. When the car 8 stops at any floor, the car door panel 13 faces the landing door panel 7 provided at that floor.

[0015] The control panel 9 is a device that controls the operation of the elevator 1. The operation of the elevator 1 controlled by the control panel 9 includes, for example, the running of the car 8 and the opening and closing of the door panel of the elevator 1. The opening and closing of the door panel of the elevator 1 is performed, for example, via the door device 14 as follows. When the car 8 stops at any floor, the door device 14 opens and closes the car door panel 13 based on a control signal from the control panel 9. At this time, the car door panel 13 opens and closes the opposing hall door panel 7 at that floor in conjunction with each other.

[0016] FIG. 2 is a perspective view of the car door 11 according to the first embodiment. In FIG. 2, a front perspective view of the car door panel 13 is shown. In this example, the direction from the inside of the car 8 toward the front of the car door panel 13 is defined as the forward direction.

[0017] The car door 11 includes two car door panels 13. One car door panel 13 is disposed on the left side of the car door 11. The other car door panel 13 is disposed on the right side of the car door 11. In each car door panel 13, the outer side in the left-right direction is the door trailing side. In each car door panel 13, the inner side in the left-right direction is the door leading side. During an opening operation, each car door panel 13 moves parallel to the door trailing side and is stored in a door pocket. The door pocket is a space in which the car door panel 13 is stored when it is fully open. The door pocket is, for example, a space on the landing 3 side of the sleeve wall 12. During a closing operation, each door panel moves parallel to the door leading side after leaving the door pocket.

[0018] The door device 14 includes a door motor 15 and a control unit 16. The door motor 15 is a device that generates a driving force for opening and closing the car door panel 13. The control unit 16 is a part that controls the operation of the door motor 15. The control unit 16 controls the door motor 15 to generate a driving force based on a control signal from the control panel 9, for example.

[0019] A door control device 17 is applied to the elevator 1. The door control device 17 is a part that controls opening and closing of door panels of the car door 11 and the landing door 5 linked to the car door 11. The control device 17 includes a door device 14. The control device 17 is equipped with a state determination device 18. The state determination device 18 is equipped with a pressure-sensitive sheet 19, a memory unit 20, a calculation unit 21, and a determination unit 22. The memory unit 20, the calculation unit 21, and the determination unit 22 are mounted on, for example, a processing circuit of the state determination device 18.

[0020] The pressure-sensitive sheet 19 is a sheet-like sensor provided on the door of the elevator 1. The pressure-sensitive sheet 19 is provided on at least one of the car door 11 and the hall door 5. The pressure-sensitive sheet 19 is provided on at least one of the door panel and the door frame of the elevator 1 door.

[0021] In this example, the pressure-sensitive sheet 19 is provided on the car door panel 13 of the car door 11. The pressure-sensitive sheet 19 is attached to the front of the car door panel 13. The front of the car door panel 13 is a surface that extends in the left-right direction. The pressure-sensitive sheet 19 is equipped with a function of detecting the pressed position when pressed by a detectable object. The detectable object is, for example, the user's hand or finger, or an object held by the user. The pressure-sensitive sheet 19 is, for example, a combination of linear detection parts (not shown) that can detect pressure due to pressing, arranged vertically and horizontally at equal pitches. The pressure-sensitive sheet 19 detects the pressed position by, for example, a combination of vertical and horizontal detection parts that detect pressure.

[0022] The memory unit 20 is a part that stores information. Time series data that represents changes in the pressure position detected by the pressure-sensitive sheet 19 is stored in the memory unit 20. Here, the time series data is a series of multiple pieces of data measured over time. The time series data is a series of multiple pieces of data acquired at a preset time interval, for example. Each piece of data included in the time series data represents a pressure position detected by the pressure-sensitive sheet 19.

[0023] The calculation unit 21 has a function of detecting continuous movement of the pressed position based on time series data representing the change in the pressed position. The calculation unit 21 reads the time series data representing the change in the pressed position from the storage unit 20. When the calculation unit 21 detects continuous movement of the pressed position, it calculates the movement direction of the pressed position. For example, when the pressed position continuously moves to the left, the calculation unit 21 calculates the movement direction of the pressed position as left. When the pressed position continuously moves to the right, the calculation unit 21 calculates the movement direction of the pressed position as right. During this time, the pressed position may also continuously move downward.

[0024] The determination unit 22 determines a change in the state of the elevator door 1 caused by the detected object based on the moving direction of the pressing position calculated by the calculation unit 21. In this example, the determination unit 22 determines a change in the state of the car door 11 caused by the detected object. The state of the car door 11 includes, for example, a normal state and an abnormal state. The normal state is the state of the car door 11 in normal operation. The normal state is, for example, a state in which the detected object does not hit the car door panel 13. The abnormal state is a state that is not the normal state. The abnormal state includes an operation state. The operation state is, for example, a state in which a user is operating the car door 11. In this case, the detected object is, for example, the hand of the user performing the operation. The operation by the user includes, for example, an emergency stop or reversal of the opening and closing of the car door panel 13. The abnormal state may include a state that is not based on the user's intention, such as a state in which the detected object is rubbing against the car door panel 13 or a state in which the detected object is pulled into a door pocket.

[0025] A car operation panel 23 is provided in the elevator 1. The car operation panel 23 is a part inside the car 8 that accepts operations by the user. Operations accepted by the car operation panel 23 include an operation for registering a car call and an operation for opening and closing the car door panel 13. The car operation panel 23 is provided, for example, on the sleeve wall 12. The car operation panel 23 outputs a control signal based on the accepted operation to the control unit 16 of the door device 14, etc. The car operation panel 23 may output the control signal via the control panel 9, etc.

[0026] FIG. 3 is a perspective view of the car door 11 according to the first embodiment. FIG. 3 shows the car door panel 13 in the process of being opened from the state shown in FIG.

[0027] In elevator 1, when something held by a user or the user's hand, etc., is in contact with the open car door panel 13, the user's hand, etc. may be about to be pulled into the door pocket together with the car door panel 13. In such a case, the user or another user attempts to perform an operation to stop or reverse the opening operation of the car door panel 13. The user who wishes to perform the operation performs an operation regarding the opening operation of the car door panel 13 via the car operation panel 23, for example.

[0028] On the other hand, when the elevator is crowded or in an emergency, a user who wishes to operate the elevator may not be able to reach the car operating panel 23. In such a case, the user may operate the car door panel 13 to open the car door panel 13 through the pressure-sensitive sheet 19 provided on the car door panel 13, for example, as follows.

[0029] The user touches the pressure-sensitive sheet 19 with his / her hand and pushes it from the front toward the landing 3. While the user is pushing the pressure-sensitive sheet 19, the pressing position does not move. At this time, the pressure-sensitive sheet 19 detects the pressing by the user. The memory unit 20 stores time-series data of the detected pressing position. The calculation unit 21 detects that the pressing position has not moved based on the time-series data stored in the memory unit 20. The determination unit 22 determines that the state of the car door 11 has changed from the normal state to an operation state corresponding to the user's pushing operation based on the detection result of the calculation unit 21. The determination unit 22 outputs the determination result to the control unit 16 of the door device 14. Alternatively, the determination unit 22 may output the determination result to the control unit 16 of the door device 14 through the control panel 9. The control unit 16, which has received the determination result of the change to the operation state corresponding to the pushing operation, stops the opening operation of the car door panel 13.

[0030] Alternatively, the user may touch the pressure-sensitive sheet 19 and move his / her hand on the pressure-sensitive sheet 19 in the opposite direction to the direction in which the car door panel 13 opens. The user's swipe operation, i.e., the user's moving his / her hand on the pressure-sensitive sheet 19, causes the pressing position to move continuously. During this time, the pressure-sensitive sheet 19 detects the pressing by the user. The storage unit 20 stores time-series data of the detected pressing position. The calculation unit 21 detects the continuous movement of the pressing position based on the time-series data stored in the storage unit 20. The calculation unit 21 calculates the moving direction of the pressing position. Based on the detection result of the calculation unit 21, the determination unit 22 determines that the state of the car door 11 has changed from the normal state to an operation state corresponding to the user's swipe operation in the opposite direction to the opening and closing direction. The determination unit 22 outputs the determination result to the control unit 16 of the door device 14. Alternatively, the determination unit 22 may output the determination result to the control unit 16 of the door device 14 through the control panel 9. The control unit 16, which has received the determination result that the operation state has changed to correspond to a swipe operation in the opposite opening / closing direction, reverses the opening operation of the car door panel 13.

[0031] The state determination device 18 performs the same determination regardless of the presence or absence of an intentional operation by the user. That is, similar to the determination of a change to an operation state corresponding to a swipe operation in the opposite opening / closing direction, the state determination device 18 may determine a change to a state in which a detectable object such as a user's hand is rubbing against the car door panel 13. At this time, the determination unit 22 may handle the operation state corresponding to a swipe operation in the opposite opening / closing direction and the state in which a detectable object is rubbing against the car door panel 13 without distinguishing between them.

[0032] The state determination device 18 performs a similar determination even when the car door panel 13 performs a closing operation. The control device 17 performs a similar control based on the determination of the state determination device 18 even when the car door panel 13 performs a closing operation.

[0033] Furthermore, the state determination device 18 detects the state in which the detectable object is drawn into the door pocket when something held by the user or the user's hand is drawn into the door pocket, for example, as follows. When the detectable object is drawn into the door pocket, the pressing position is inside the door pocket, that is, outside the car entrance 10 in the left-right direction. The determination unit 22 determines that the pressing position is outside the car entrance 10 based on the pressing position on the pressure-sensitive sheet 19 and the position of the car door panel 13 itself. When the detectable object is drawn into the door pocket, the detectable object rubs against the car door panel 13, so the pressing position moves continuously on the car door panel 13. Therefore, when the pressing position is outside the car entrance 10 and the pressing position moves continuously, the determination unit 22 determines that the detectable object has changed to a state in which it is drawn into the door pocket. The determination unit 22 outputs the determination result to the control unit 16 of the door device 14. Alternatively, the determination unit 22 may output the determination result to the control unit 16 of the door device 14 through the control panel 9. The control unit 16, which has received the determination result that the state has changed so that the detectable object is pulled into the door pocket, temporarily stops the opening operation of the car door panel 13 and then reverses it.

[0034] The pressure-sensitive sheet 19 may be provided on the landing door panel 7 of the landing door 5. In this case, the state determination device 18 and the control device 17 operate in the same manner as in the case where the pressure-sensitive sheet 19 is provided on the car door panel 13 of the car door 11. The pressure-sensitive sheet 19 may be provided on both the car door panel 13 and the landing door panel 7.

[0035] FIG. 4 is a flowchart showing an example of the operation of the control device 17 according to the first embodiment. The process of FIG. 4 starts, for example, when the car door panel 13 is opened or closed.

[0036] In step S1, the pressure-sensitive sheet 19 detects a pressure applied by a detection object. At this time, time-series data of the detected pressure position is stored in the storage unit 20. Thereafter, the control device 17 proceeds to the process of step S2.

[0037] In step S2, the determination unit 22 determines whether the pressing position is continuously moving inside the door pocket. If the determination result is Yes, the control device 17 proceeds to the process of step S3. If the determination result is No, the control device 17 proceeds to the process of step S4.

[0038] In step S3, the control unit 16 temporarily halts the opening / closing operation of the car door panel 13. After that, the control unit 16 reverses the opening / closing operation of the car door panel 13. After that, the control device 17 ends the process related to the determination of the change in the state of the car door 11 during the opening / closing operation of the car door panel 13.

[0039] In step S4, the determination unit 22 determines whether the pressing position is continuously moving in the opposite direction to the opening / closing direction. If the determination result is Yes, the control device 17 proceeds to the process of step S5. If the determination result is No, the control device 17 proceeds to the process of step S6.

[0040] In step S5, the control unit 16 reverses the opening and closing operation of the car door panel 13. Thereafter, the control device 17 ends the process related to the determination of the change in the state of the car door 11 during the opening and closing operation of the car door panel 13.

[0041] In step S6, the control unit 16 temporarily halts the opening / closing operation of the car door panel 13. Thereafter, the control device 17 ends the process related to determining the change in the state of the car door 11 during the opening / closing operation of the car door panel 13.

[0042] As described above, the control device 17 according to the first embodiment includes the state determination device 18 and the control unit 16. The state determination device 18 includes the pressure-sensitive sheet 19, the storage unit 20, the calculation unit 21, and the determination unit 22. The pressure-sensitive sheet 19 is a sensor provided on a surface along the opening and closing direction of the door panel. The pressure-sensitive sheet 19 detects the pressed position when pressed by a detectable object. The storage unit 20 stores the change in the pressed position of the detectable object detected by the pressure-sensitive sheet 19 as time-series data. The calculation unit 21 calculates the moving direction of the pressed position of the detectable object when detecting continuous movement of the pressed position of the detectable object based on the time-series data stored in the storage unit 20. The determination unit 22 determines the change in the state of the car door 11 caused by the detectable object based on the moving direction of the pressed position of the detectable object calculated by the calculation unit 21. The control unit 16 controls the opening and closing operation of the car door panel 13 based on the change in the state of the door determined by the state determination device 18.

[0043] With this configuration, the pressure-sensitive sheet 19 provided on the front surface of the car door panel 13 or the like can determine a change in state of the car door 11 caused by a detectable object that does not hit the door edge of the car door panel 13. As a result, control of the elevator 1 doors, such as the car door 11, reflects a change in state caused by a detectable object that hits the front surface of the car door panel 13 or the like. Also, since the opening and closing operation of the car door panel 13 can be operated through the pressure-sensitive sheet 19 provided on the car door panel 13, even a user who is located away from the car operation panel 23 can perform the operation. Also, since there is no need to touch the door edge of the car door panel 13, the psychological resistance of users to the operation can be reduced.

[0044] In addition, when the calculation unit 21 detects continuous movement of the pressing position of the detectable object during the opening and closing operation of the car door panel 13, the judgment unit 22 judges that the state of the car door 11 due to the detectable object has become abnormal.

[0045] This configuration enables the opening and closing of the car door panel 13 to be controlled using an intuitive interface, such as a swipe operation.

[0046] Furthermore, the determination unit 22 may detect continuous movement of the pressing position of the detection object by the calculation unit 21 during the opening and closing operation of the car door panel 13. At this time, when the moving direction of the pressing position of the detection object calculated by the calculation unit 21 is the opposite direction to the opening and closing operation direction of the car door panel 13, the determination unit 22 determines that the detection object is in a rubbing state, which is an abnormal state.

[0047] With this configuration, it is possible to detect whether a person, such as a user, or an object is rubbing against the car door panel 13. Therefore, the control of the car door 11 and other doors is adapted to the situation, such as a state in which a person or an object is rubbing against the car door panel 13.

[0048] Furthermore, during the opening and closing operation of the car door panel 13, the calculation unit 21 may detect continuous movement of the pressed position of the detectable object outside the car entrance 10. At this time, when the moving direction of the pressed position of the detectable object calculated by the calculation unit 21 is the opposite direction to the opening and closing operation of the car door panel 13, the determination unit 22 determines that the detectable object has entered a pulled-in state, which is an abnormal state.

[0049] With this configuration, it is possible to detect that a person or object, such as a user, is being pulled in by the car door panel 13. Therefore, the control of the doors, such as the car door 11, is adapted to the situation, such as the state in which a person or object is being pulled in.

[0050] Next, an example of the hardware configuration of the control device 17 will be described with reference to FIG. FIG. 5 is a hardware configuration diagram of a main part of the control device 17 according to the first embodiment.

[0051] Each function of the control device 17, including the state determination device 18, may be realized by a processing circuit. The processing circuit includes at least one processor 100a and at least one memory 100b. The processing circuit may include at least one dedicated hardware 200 together with the processor 100a and the memory 100b or in place of them.

[0052] When the processing circuit includes a processor 100a and a memory 100b, each function of the control device 17 is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. The program is stored in the memory 100b. The processor 100a realizes each function of the control device 17 by reading and executing the program stored in the memory 100b.

[0053] The processor 100a is also called a CPU (Central Processing Unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The memory 100b is composed of a non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM.

[0054] Where the processing circuitry comprises dedicated hardware 200, the processing circuitry may be implemented, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

[0055] Each function of the control device 17 can be realized by a processing circuit. Alternatively, each function of the control device 17 can be realized collectively by a processing circuit. Some of the functions of the control device 17 may be realized by dedicated hardware 200, and the other parts may be realized by software or firmware. In this way, the processing circuit realizes each function of the control device 17 by dedicated hardware 200, software, firmware, or a combination of these.

[0056] Embodiment 2 In the second embodiment, differences from the example disclosed in the first embodiment will be described in particular detail. For features not described in the second embodiment, any of the features of the example disclosed in the first embodiment may be adopted.

[0057] FIG. 6 is a perspective view of the car door 11 according to the second embodiment. In FIG. 6 the left car door panel 13 and the left sleeve wall 12 are shown.

[0058] In this example, the pressure-sensitive sheet 19 is provided on the car door panel 13 and the sleeve wall 12 of the car door 11. The pressure-sensitive sheet 19 provided on the car door panel 13 is attached to the front surface of the car door panel 13. The front surface of the car door panel 13 is a surface that extends in the left-right direction. The pressure-sensitive sheet 19 provided on the sleeve wall 12 is attached to the inner surface of a door pocket that faces the car door panel 13 in the sleeve wall 12. The inner surface of the door pocket of the sleeve wall 12 is a surface that extends in the left-right direction.

[0059] The state determination device 18 detects a state in which a detectable object is drawn into the door pocket when something held by a user or the user's hand is drawn into the door pocket, for example, as follows. When the detectable object is drawn into the door pocket, the pressing position is inside the door pocket, that is, outside the car entrance 10 in the left-right direction. The determination unit 22 determines that the pressing position is outside the car entrance 10 based on the pressing position on the pressure-sensitive sheet 19 provided on the car door panel 13 and the position of the car door panel 13 itself. In addition, since the pressure-sensitive sheet 19 provided on the sleeve wall 12 is inside the door pocket, the determination unit 22 determines that the pressing position detected on the pressure-sensitive sheet 19 is outside the car entrance 10. Since the detectable object moves together with the car door panel 13 when it is drawn into the door pocket, the pressing position moves continuously in the same direction as the car door panel 13 on the pressure-sensitive sheet 19 provided on the sleeve wall 12. Therefore, when the pressing position is outside the car entrance 10 and the pressing position is continuously moving, the determination unit 22 determines that the state has changed to one in which the detectable object is pulled into the door pocket. The determination unit 22 outputs the determination result to the control unit 16 of the door device 14. Alternatively, the determination unit 22 may output the determination result to the control unit 16 of the door device 14 via the control panel 9. The control unit 16, which has received the determination result that the state has changed to one in which the detectable object is pulled into the door pocket, temporarily stops the opening operation of the car door panel 13 and then reverses it.

[0060] The pressure-sensitive sheet 19 may be provided on the landing door panel 7 and the jamb 6 of the landing door 5. In this case, the state determination device 18 and the control device 17 operate in the same manner as in the case where the pressure-sensitive sheet 19 is provided on the car door panel 13 and the sleeve wall 12 of the car door 11. The pressure-sensitive sheet 19 may be provided on both the car door 11 and the landing door 5.

[0061] As described above, the state determination device 18 according to the second embodiment includes the pressure-sensitive sheet 19, the storage unit 20, the calculation unit 21, and the determination unit 22. The pressure-sensitive sheet 19 is a sensor provided on the surface of the car door panel 13 and the sleeve wall 12 along the opening and closing direction of the car door panel 13. The pressure-sensitive sheet 19 detects the pressed position when pressed by a detectable object. The storage unit 20 stores the change in the pressed position of the detectable object detected by the pressure-sensitive sheet 19 as time-series data. The calculation unit 21 calculates the moving direction of the pressed position of the detectable object based on the time-series data stored in the storage unit 20 when detecting continuous movement of the pressed position of the detectable object. The determination unit 22 determines a change in the state of the car door 11 caused by the detectable object based on the moving direction of the pressed position of the detectable object calculated by the calculation unit 21. Further, the pressure-sensitive sheet 19 is provided on the sleeve wall 12. The calculation unit 21 may detect continuous movement of the pressing position of the detection object during the opening and closing operation of the car door panel 13. At this time, when the moving direction of the pressing position of the detection object calculated by the calculation unit 21 is the same direction as the opening and closing operation of the door panel, the determination unit 22 determines that the detection object has entered a pulled-in state, which is an abnormal state.

[0062] With this configuration, it is possible to detect that a person or object, such as a user, is being pulled in by the car door panel 13. Therefore, the control of the doors, such as the car door 11, is adapted to the situation, such as the state in which a person or object is being pulled in.

[0063] Embodiment 3 In the third embodiment, differences from the examples disclosed in the first and second embodiments will be described in particular detail. For features not described in the third embodiment, any of the features of the examples disclosed in the first and second embodiments may be adopted.

[0064] FIG. 7 is a perspective view of a car door 11 according to the third embodiment. In FIG. 7, the left car door panel 13 is shown.

[0065] The state determination device 18 includes an attachment portion 24a. The attachment portion 24a is a plate-shaped member that is detachably attached to the front surface of the car door panel 13. The attachment portion 24a is attached to the car door panel 13 by a fastener 25. The fastener 25 is, for example, a screw. The pressure-sensitive sheet 19 is attached to the attachment portion 24a. As a result, the pressure-sensitive sheet 19 is detachably attached to the car door panel 13 via the attachment portion 24a.

[0066] FIG. 8 is a perspective view of a car door 11 according to the third embodiment. In FIG. 8 the left sleeve wall 12 is shown.

[0067] The state determination device 18 includes an attachment portion 24b. The attachment portion 24b is a plate-like member bent into an L-shape. One of the L-shaped bent surfaces of the attachment portion 24b is detachably attached to the inner surface of the door pocket facing the car door panel 13 in the sleeve wall 12. The attachment portion 24b is attached to the sleeve wall 12 by a fastener 25. The fastener 25 is, for example, a screw. In this example, the fastener 25 attaches the attachment portion 24b to a surface perpendicular to the left-right direction of the sleeve wall 12. The pressure-sensitive sheet 19 is attached to the attachment portion 24b. As a result, the pressure-sensitive sheet 19 is detachably attached to the sleeve wall 12 via the attachment portion 24b.

[0068] The pressure-sensitive sheet 19 may be similarly detachably attached to the landing door panel 7 and the jamb 6 of the landing door 5.

[0069] As described above, the pressure-sensitive sheet 19 of the state determination device 18 according to the third embodiment is detachably attached to the sleeve wall 12 or the car door panel 13.

[0070] This configuration makes it easy to attach the pressure-sensing sheet 19. This makes it easy to apply the state determination device 18 to an existing elevator 1 or the like. [Explanation of symbols]
