Description

TECHNICAL FIELD The present invention relates to an elevator, and more particularly, to an elevator including a non-contact operation panel.

A car operation panel is installed in the car of the elevator. The car operation panel includes a destination floor button that displays numbers and the like of the destination floor. The passenger operates the destination floor button to register the destination floor of the car moving in the hoistway. As the destination floor button, a contact type button such as a push button or a touch panel graphical user interface (GUI) is widely adopted.

In recent years, in elevators installed in public facilities, etc., a non-contact type car operation panel that allows non-contact operation of car destination floor registration has been introduced in consideration of hygiene. .. In this type of car operation panel, a passenger's operation of destination floor registration is detected by a distance sensor or a photoelectric sensor in a non-contact manner (for example, Patent Documents 1-3).

In the non-contact type car operation panel described above, the following measures are taken to prevent passengers from accidentally registering the wrong destination floor. For example, the detection distance of the sensor is set within a specific range close to the car operation panel so that the operation at a position away from the sensor is not detected. In addition, by setting a certain threshold time until it is determined that the operation has been detected, the detection of an accidental event that somehow grabs the detection area of the sensor for a moment is eliminated.

By the way, the car may become full during times when passengers using the elevator are crowded. In that case, it is assumed that passengers are forced to stand in a position close to the car operation panel. Further, even if the inside of the car is not full, it is possible that the passenger suddenly leans on the car operation panel, or the passenger's baggage is approaching the car operation panel without realizing. In such a situation, there is a possibility that the destination floor may be erroneously registered even if the above measures are taken.

In addition, when the hall operation panel installed in the hall of the elevator is a non-contact type, it is considered that the same situation may occur in the hall. Therefore, the above-mentioned problems are common not only to the car operation panel but also to the hall operation panel.

In view of the above-mentioned problem, the present invention has an object to provide an elevator that can prevent an accidental registration of a destination floor that a passenger does not intend even in the above situation.

In order to achieve the above object, the elevator according to the present invention detects a non-contact operation panel having a plurality of sensors for non-contactly detecting an operation for determining a destination floor of a car moving in a hoistway, and the operation. Based on the detection conditions to do, a control device for controlling whether to register the destination floor, and, the control device, a destination floor sensor corresponding to the destination floor of the plurality of sensors When the operation is continuously detected until the first threshold time, the destination floor is registered, and when the operation is continuously detected until the second threshold time, a process of notifying that the registration is canceled is executed. The registration is canceled.

Further, the plurality of sensors include an adjacent sensor adjacent to the destination floor sensor, the control device, by the time the first threshold time has elapsed, both the destination floor sensor and the adjacent sensor performs the operation. If detected, the destination floor is unregistered.

Furthermore, when the third threshold time elapses after both the destination floor sensor and the adjacent sensor detect the operation, the control device executes a process of issuing a warning that both of them detect the operation. It is characterized by doing.

According to the elevator of the present invention, the destination floor sensor of the non-contact type operation panel detects the operation of continuously determining the destination floor of the car until the first threshold time, and even if the destination floor is registered, When the operation is continuously detected until the second threshold time, the control device executes a process of notifying that the registration is canceled and cancels the registration. It is possible to make the passenger aware of a situation that may occur and prompt the user to re-register the destination floor. Accordingly, even in the above situation, it is possible to prevent the passenger from unintentionally registering the wrong destination floor.

Embodiments of an elevator according to the present invention will be described below with reference to the drawings.

<First Embodiment>
As shown in FIG. 1, an elevator 10 according to the first embodiment is a traction type elevator having a machine room 14 at the top of a hoistway 12, and is installed in a public building such as a hospital or a nursing facility. .. A main rope 20 is hung on the drive sheave 18 of the hoisting machine 16 installed in the machine room 14, a car 22 is connected to one end of the main rope 20, and a counterweight 24 is connected to the other end. Has been done.

Rotational power from a motor (not shown) of the hoisting machine 16 is transmitted to the drive sheave 18 via a power transmission mechanism (not shown), and when the drive sheave 18 is rotationally driven, the main rope 20 is accompanied. And the car 22 suspended by the main rope 20 is guided by a guide rail (not shown) to move vertically in the hoistway.

In the building in which the elevator 10 is installed, halls 26A, 26B, and 26C are provided for different floors, respectively. While the elevator 10 is operating, the car 22 is currently on the floor of the floor (in FIG. 1). , From the hall 26C) to the hall on the next destination floor (for example, the hall 26A) is repeated.

A car operation panel 28 (FIG. 2) is installed in the car 22. The car operation panel 28 is provided on either one of the left and right sleeve walls of the entrance (not shown) on the halls 26A, 26B, 26C side of the car 22. A passenger using the elevator 10 operates the car operation panel 28 to determine the destination floor of the car 22.

As shown in FIG. 2, the car operation panel 28 includes a destination floor operation unit 30 that allows passengers to perform an operation of determining the destination floor of the car 22. The destination floor operation unit 30 is provided with a plurality of sensors 32A, 32B,... 32C that detect the operation in a non-contact manner. Each of the sensors 32A, 32B,... 32C corresponds to each floor where the halls 26A, 26B, 26C are located. In this example, the first to fourth floors and the sixth and tenth floors can be the destination floors. For example, the sensor 32B detects an operation for determining the second floor as the destination floor.

In the destination floor operation unit 30, a reflective photoelectric sensor in which a light projector and a light receiver are integrated is used as each of the sensors 32A, 32B,... 32C. This reflection type photoelectric sensor emits light from a light projector and detects the presence or absence of an object based on the amount of reflected light received by the light receiver from the object. In this example, the amount of light received by the light receiver (sensor sensitivity) is adjusted, and the detection distance of the sensor is set within a range of about 5 cm from the destination floor operation unit 30. When the reflective photoelectric sensor detects an object, a detection signal is transmitted to the control device 46 (FIG. 1) described later.

The destination floor operation unit 30 includes a rectangular panel portion 34, and sensors 32A, 32B,... 32C are arranged at intervals in the longitudinal direction of the panel portion 34. Rectangular holes are respectively formed in the panel portion 34 at the positions where the sensors 32A, 32B,... 32C are arranged. The reflection type photoelectric sensor is housed in the inner side of each of the rectangular holes, and each of the rectangular holes is covered with a light-transmitting protective plate 36A, 36B,... 36C. Each of the protection plates 36A, 36B,... 36C is provided with a mark for guiding the passenger's operation.

The adjacent sensors among the sensors 32A, 32B,... 32C have a distance of about 10 cm (generally about one fistula). By arranging each of the sensors 32A, 32B,... 32C whose detection distances are set within the above range with such an interval, the passenger temporarily stands in front of the destination floor operation unit 30 and puts his or her finger or palm on the palm. Even if an operation for determining the destination floor is performed by holding over the specific sensor, it is possible to prevent the situation where the sensor corresponding to the adjacent floor erroneously detects the operation as much as possible.

In the panel portion 34, numbers indicating the corresponding floors are displayed on the left side of each of the sensors 32A, 32B,... 32C. Further, on the panel portion 34, L-shaped delimiter lines 37A, 37B,... 37C for demarcating the combinations of the sensors 32A, 32B,... Each of these numbers and break lines 37A, 37B,... 37C is a translucent portion formed of a translucent member, and when a lamp (not shown) stored on the back side thereof emits light, the numbers and break lines are separated. 37A, 37B,..., 37C are configured to be turned on (in FIG. 2, a state is shown in which the translucent portion corresponding to the second floor is turned on).

An open button 38 and a close button 40 for opening and closing a car door (not shown) are juxtaposed below the destination floor operation unit 30. A contact button 42 for contacting the outside is provided on the upper part of the destination floor operation unit 30. It should be noted that all of these buttons 38, 40, 42 are conventionally known push buttons, but like the destination floor operation unit 30 described above, a non-contact type may be adopted.

The car operation panel 28 further includes a display unit 44. The display unit 44 is, for example, a liquid crystal display, and displays, for example, the moving direction of the car 22, the passing floor of the car 22, and other information to be notified to passengers. The display unit 44 is provided at a position above the destination floor operation unit 30 so as to be easily seen by passengers. The car operation panel 28 also incorporates a speaker (not shown) for outputting sound.

In addition, in the destination floor operation unit 30 of the car operation panel 28, each of the above-mentioned protective plates 36A, 36B,... 36C and the translucent part (numerals, separating lines 37A, 37B,... 37C) is a cab room (panel room 34). It has a flat shape that is provided flush with the main surface on the (not shown) side. The display unit 44 is provided flush with the flat main surface of the destination floor operation unit 30 on the cab side, and the open button 38, the close button 40, and the contact button 42 are provided flush with each other. ing. Therefore, the car operation panel 28 has a flat appearance as a whole.

The non-contact type car operation panel 28 having the above configuration is electrically connected to the control device 46 installed in the machine room 14 (FIG. 1). The control device 46 is a computer that performs overall operation control of the elevator 10, and has a basic function such as a CPU and a memory, and a timer function. The memory stores various control programs for controlling the drive of the hoisting machine 16 and the opening/closing control of a car door (not shown), for example. The CPU reads out these programs from the memory and executes the programs, so that the smooth operation of the elevator 10 by the control device 46 is realized.

In the elevator 10 having the above-described configuration, the control device 46 also controls the destination floor registration of the car 22. The memory of the control device 46 stores a control program for registration of the destination floor of the car 22. The control device 46 controls the destination floor registration of the car 22 by the CPU reading the control program from the memory and executing the series of judgments and processes shown in FIG.

Here, the control device 46 controls the destination floor registration of the car 22 based on the detection signal transmitted from the sensors 32A, 32B,... 32C of the car operation panel 28, but immediately upon receiving the detection signal. Instead of registering as a destination floor, detection conditions are set for detecting an operation that determines the destination floor. Specifically, while monitoring the duration of the detection signal with a timer, depending on the situation, it is determined whether or not this duration has passed the first to third threshold times, and based on the result, the destination floor Is configured to control whether or not to register.

Hereinafter, the control of the destination floor registration of the car 22 in the elevator 10 will be specifically described with reference to FIG. 3 by taking the case of registering the second floor as the destination floor as an example. It is assumed that the car 22 is currently landed at the hall 26C (FIG. 1) on the 10th floor, which is the top floor, and the car door (not shown) is open.

The control device 46 (CPU) first confirms whether or not the second floor can be registered (S1). The state in which the second floor cannot be registered may be, for example, a state in which the elevator 10 is not in operation, a state in which the elevator is on the second floor, a state in which the second floor is already registered as the destination floor, or the like.

If the second floor is not registered (S1: NO), the process waits until the second floor can be registered. On the other hand, when the second floor can be registered (S1: YES), it is confirmed whether or not there is a detection signal from the sensor 32B that detects an operation for determining the second floor as the destination floor, and the sensor 32B is adjacent to the sensor 32B. It is confirmed whether or not there is a detection signal from the adjacent sensor (S2).

The "adjacent sensor" here refers to the sensor 32A corresponding to the first floor which is the adjacent floor of the second floor serving as the destination floor and the sensor corresponding to the third floor. In this example, there are two adjacent sensors, but when the destination floor is the lowest floor (first floor) or the highest floor (10th floor), there is one adjacent sensor.

When there is a detection signal from the sensor 32B and no detection signal from the adjacent sensor (S2: YES), it is determined whether the duration of the detection signal from the sensor 32B has exceeded the first threshold time. (S3). Then, when the first threshold time has elapsed (S3: YES), the second floor is registered as the destination floor (S4). Specifically, the control device 46 turns on the destination floor registration flag of the second floor, and turns on the number "2" displayed on the destination floor operation unit 30 of the car operation panel 28 and the corresponding dividing line 37B. At the same time, the speaker outputs a simple registered sound.

On the other hand, if the duration of the detection signal from the sensor 32B does not exceed the first threshold time (S3: NO), even if there is a detection signal from the sensor 32B, the second floor is registered as the destination floor. Does not take place and shifts to the standby state.

The above-mentioned first threshold time is, for example, about 0.3 seconds. By setting such a first threshold time, the elevator 10 causes the sensors 32A, 32B,... 32C to detect any objects including a part of the passenger's body in the destination floor operation unit 30 of the car operation panel 28. This prevents accidental events such as squeezing each detection area for a moment as an operation for determining the destination floor of the car 22.

At this point, the second floor has already been registered as the destination floor, but in the elevator 10, the control device 46 continuously monitors the detection signal from the sensor 32B and confirms whether or not the detection signal continues. Yes (S5). Then, if the detection signal from the sensor 32B is not continued (S5: NO), the determination/processing is ended there, and the destination floor registration of the car 22 on the second floor is completed.

On the other hand, if the detection signal from the sensor 32B is still continuing (S5: YES), the control device 46 determines whether or not the second threshold time has elapsed after the first threshold time has elapsed (S6). .. If the detection signal from the sensor 32B does not continue until the second threshold time elapses (S6:NO), it is determined again after confirming that the detection signal does not continue (S5:NO). -The process is completed, and the destination floor registration of the car 22 on the second floor is completed.

However, when the detection signal from the sensor 32B continues until the second threshold time elapses (S6: YES), the control device 46 releases the already completed destination floor registration (S4) of the second floor (S4). S7). Specifically, the control device 46 turns off the number "2" displayed on the destination floor operation unit 30 of the car operation panel 28 and the corresponding dividing line 37B, and outputs a notification sound from the speaker. Alternatively, by displaying a notification image on the display unit 44, a process of notifying the passenger that the second floor destination floor registration is canceled is executed, and the second floor destination floor registration flag is returned from ON to OFF. Then, when the registration of the destination floor on the second floor is canceled, the control device 46 ends the determination/processing.

The above-mentioned second threshold time is, for example, about 5 seconds. By setting such a second threshold time and incorporating the process for canceling the registration of the destination floor, in the elevator floor 10, in the destination floor operation unit 30 of the car operation panel 28, for example, one of the sensors 32A, 32B,... 32C is selected. One of them continues to detect a part of the passenger's body, baggage, etc., or the sensor itself turns ON, which causes these events to be erroneously detected as an operation for registering the destination floor, resulting in the passenger's intention. The control that can prevent the wrong registration of the destination floor is realized.

Further, even if the destination floor registration that has already been completed is canceled, the fact is notified to the passengers, so that the passengers can be prompted to re-register the destination floor. Therefore, it is less likely that a passenger using the elevator 10 will be confused.

By the way, in the above-mentioned car operation panel 28, in the destination floor operation unit 30, it is assumed that both the sensor 32B and the adjacent sensor detect the operation at the same time. At this time, the control device 46 enters a state in which there is a detection signal from the sensor 32B and also a detection signal from the adjacent sensor (S2: NO). In this case, the control device 46 confirms that there is a detection signal from the sensor 32B corresponding to the second floor, which is the destination floor (S8).

At this point, if the detection signal from the sensor 32B cannot be confirmed (S8: NO), it shifts to the standby state. On the other hand, if the detection signal from the sensor 32B can be confirmed (S8: YES), whether the duration of the state in which there is the detection signal from the sensor 32B and also the detection signal from the adjacent sensor has exceeded the third threshold time. It is judged (S9).

If this state (the state in which the detection signals from the sensor 32B and the adjacent sensor are present) does not continue until the third threshold time elapses (S9: NO), the standby state is entered. On the other hand, when this state continues until the third threshold time elapses (S9: YES), the control device 46 warns that both the sensor 32B and the adjacent sensor detect the operation (S10). Specifically, the control device 46 outputs a warning sound from the speaker of the car operation panel 28 or executes a warning process such as displaying a warning image on the display unit 44. Then, when the warning process is executed, the control device 46 ends the determination/process.

The above-mentioned third threshold time is, for example, about 3 seconds. By setting such a third threshold time for the duration of time when the detection signals from the sensor 32B and each of the adjacent sensors are present, in the elevator 10, there is a possibility that false registration of the destination floor may occur. It is recognizable. For example, the standing position of passengers in the car 22 or baggage is too close to the car operation panel 28, or the passenger leans on the car operation panel 28. Then, since a warning is given for such a situation, the passenger can recognize the fact. As a result, it not only contributes to the elimination of the situation, but also leads to the prevention of recurrence.

Further, in the elevator 10 of the present embodiment, the above determination when both the sensor 32B and the adjacent sensor detect the operation is executed at the timing until the first threshold time elapses, and both the sensors detect the operation. In some cases, the control that does not register the destination floor is used in the first place. As a result, even if the above situation occurs in the car 22, it is possible to reliably prevent unintended registration of the destination floor by the passenger.

<Second Embodiment>
In the first embodiment, when the destination floor (second floor) is registered, only the detection signal from the sensor (sensor 32B) corresponding to the destination floor is monitored and the presence or absence of the detection signal from the adjacent sensor is confirmed. Instead, it was decided to control the destination floor registration of the car 22. On the other hand, in the elevator according to the second embodiment, even after the destination floor (second floor) is registered, not only the detection signal from the sensor (sensor 32B) corresponding to the destination floor but also the detection from the adjacent sensor is detected. The car will continue to monitor the signals while controlling the car's destination floor registration.

The elevator according to the second embodiment has the same basic configuration as the elevator 10 according to the first embodiment, except that the control regarding the destination floor registration of the car is different. Therefore, the schematic configuration diagram of the elevator according to the second embodiment refers to the elevator 10 illustrated in FIG. 1, and hereinafter, the same reference numerals as those of the respective configurations of the elevator 10 will be used for description.

Further, in the elevator according to the second embodiment, the control until the destination floor of the car 22 is registered is substantially the same as that in the first embodiment. Therefore, regarding the control regarding the destination floor registration of the car 22 of the elevator according to the second embodiment, the description of the control part common to the first embodiment will be referred to as necessary while referring to FIG. The control part different from that of the first embodiment will be mainly described.

As shown in FIG. 4, when the second floor is registered as the destination floor (S4), the control device 46 confirms whether or not the detection signal from the sensor 32B continues (S5), as in the first embodiment. Then, if the detection signal from the sensor 32B is not continued (S5: NO), the determination/processing is ended there, and the destination floor registration of the car 22 on the second floor is completed.

On the other hand, when the detection signal from the sensor 32B is still continuing (S5:YES), the control device 46 further confirms the presence or absence of the detection signal from the adjacent sensor (S11). Then, if there is no detection signal from the adjacent sensor (S11: YES), the control device 46 determines whether or not the second threshold time has elapsed after the first threshold time has elapsed (S6).

Here, when there is a detection signal from the adjacent sensor (S11: NO), the control device 46 determines that the duration of the state in which there is the detection signal from the sensor 32B and the detection signal from the adjacent sensor is the third. It is determined whether the threshold time has elapsed (S12). Then, if this state does not continue until the third threshold time elapses (S12: NO), the control device 46 continuously monitors the detection signals from the sensor 32B and the adjacent sensors.

On the other hand, when this state continues until the third threshold time elapses (S12: YES), the control device 46 warns that both the sensor 32B and the adjacent sensor detect the operation (S10), The judgment/process is ended.

As described above, in the second embodiment, even after the destination floor (second floor) is registered, the control device 46 can monitor the detection signals from the sensor (sensor 32B) corresponding to the destination floor and the adjacent sensors. The system is configured to be able to recognize the above-mentioned situation in which the false registration of the destination floor may occur and issue a warning to the passenger.

Although the elevator according to the present invention has been described above based on the embodiment, the present invention is not limited to the above-described mode, and may be carried out in the following modes, for example.

<Modification>
(1) In the above-described embodiment, in the destination floor operation unit 30 of the car operation panel 28, the sensors 32A, 32B,... Although they are arranged in a vertical row with an interval therebetween, they may be arranged in a horizontal row with an interval in the horizontal direction. Examples of such a car operation panel include, for example, a sub-cage operation panel installed at a height at which a passenger using a wheelchair can easily operate.

(2) In the above-described embodiment and modification, each of the non-contact type sensors is arranged in one row with a gap, but the rows of these sensors may be arranged in two rows.

For example, in the destination floor operation unit 50 shown in FIG. 5A, the first sensor row C1 including the sensors 52A, 52B,... 52C corresponding to the first to fifth floors, and the sixth to tenth floors, respectively. The second sensor array C2 including the sensors 52D, 52E,... A non-contact switching sensor 54 is provided above each of the first sensor row C1 and the second sensor row C2. Each time the switching sensor 54 detects a switching operation, the sensor array capable of detecting the operation for determining the destination floor is configured to switch between the first sensor array C1 and the second sensor array C2. A switching display unit 56 is provided above the switching sensor 54. The switching display unit 56 includes left and right indicator lights 56A and 56B, and an indicator lamp on the side having a sensor column capable of detecting an operation for determining a destination floor (the first sensor column C1 is provided in FIG. 5A). The side indicator light 56A) lights up.

Even with the configuration of the destination floor operation unit 50 described above, if the control of the destination floor registration on the first sensor column C1 side and the control of the destination floor registration on the second sensor column C2 side are performed independently, Similar to the above-described embodiment, it is possible to control the destination floor registration on the first sensor row C1 side and the second sensor row C2 side, respectively. Even if the switching sensor 54 detects the switching operation of the sensor row, the already completed destination floor registration is not canceled.

The destination floor operation unit 50 configured as described above is effective for preventing error registration in the following situations, for example. When the passenger using the elevator is right-handed, when operating the first sensor row C1 on the left side, the right arm portion of the passenger has the sensors 52D, 52E,... 52F constituting the second sensor row C2 on the right side, respectively. There is a risk that the destination floor corresponding to the sensor will be erroneously registered by blocking any of the above. However, in the destination floor operation unit 50, the first sensor row C1 on the left side is operated while the respective sensors 52D, 52E,... 52F of the second sensor row C2 on the right side are disabled (undetectable). Therefore, false registration does not occur on the second sensor array C2 side.

Alternatively, in the destination floor operation unit 60 shown in FIG. 5B, a third sensor row C3 including sensors 62A, 62B,... 62C corresponding to odd floors and sensors 62D, 62E,... 62F corresponding to even floors, respectively. The fourth sensor row C4 composed of the respective sensors is arranged side by side with the heights of adjacent sensors on the left and right being different. Therefore, the sensors 62A,..., 62F corresponding to the respective floors are alternately arranged on the left and right in a zigzag pattern.

In the above-mentioned destination floor operation unit 60, for example, when registering the second floor as the destination floor, the sensor 62A corresponding to the first floor and the sensor 62B corresponding to the third floor, which are the floors adjacent to the second floor serving as the destination floor, and The three sensors of the sensor 62E corresponding to the fourth floor arranged adjacent to the sensor 62D corresponding to the second floor are “adjacent sensors”. Further, when the third floor is registered as the destination floor, the sensor 62D corresponding to the second floor which is the adjacent floor of the third floor which is the destination floor, the sensor 62E corresponding to the fourth floor, and the sensor 62B corresponding to the third floor. The four sensors, which are the sensor 62A corresponding to the first floor and the sensor corresponding to the fifth floor, which are arranged adjacent to each other, are “adjacent sensors”. As described above, in the above-mentioned destination floor operation unit 60, although the number of adjacent sensors whose detection signals should be monitored increases, it is possible to control the destination floor registration as in the above embodiment.

The destination floor operating unit 60 configured as described above has the sensors 62A,..., 62F corresponding to the respective floors arranged in a staggered manner, so that the destination floor operating unit 50 (FIG. 5A) is The distance between the left and right sensors is wide. This reduces the possibility that the left and right sensors detect an operation at the same time, and as a result, the occurrence of false registration can be reduced as much as possible without providing the switching sensor 54. Further, since no other sensor is arranged right next to each sensor 62A,..., 62F, it is possible to prevent the occurrence of false registration due to the above situation, that is, the passenger's dominant arm as much as possible.

(3) In the above embodiment, the car operation panel 28 installed in the car 22 is a non-contact type, but it is installed in each of the halls 26A, 26B, 26C (FIG. 1) provided for different floors. The operated hall operation panel (not shown) may be a non-contact type.

The hall operation panel is usually provided with a call button. This call button includes an upper call button and a lower call button, which are generally arranged vertically or horizontally adjacent to each other. The call registration operation by the upper call button or the lower call button is detected by the upper call sensor or the lower call sensor in a non-contact manner.

In this case, for example, when registering an upper call, the upper call sensor becomes the destination floor sensor and the lower call sensor becomes the adjacent sensor. On the contrary, when registering the lower call, the lower call sensor becomes the destination floor sensor and the upper call sensor becomes the adjacent sensor. Regardless of which sensor is used for call registration, the operation is to determine the destination floor of the car 22 moving in the hoistway 12 to the floor of the hall where the hall operation panel is installed. There is no change.

It should be noted that as long as it is an operation panel for performing destination floor registration, it is not limited to the hall operation panel, and may be applied to an operation panel installed at a place apart from the hall, such as a building entrance or passage. Absent.

(4) In the above embodiment, the number of the car operation panel 28 installed in the car 22 is one, but a plurality of car operation panels may be installed in the car. In this case, the destination floor registration of each car can be controlled by controlling the destination floor registration of each car operation panel independently of each other, as in the above embodiment. This also applies to the auxiliary car operation panel, which is installed at a height that is easy for a passenger using a wheelchair to operate, as shown in the above modification.

Further, not only the inside of the car 22, but a plurality of hall operation panels may be installed in each of the halls 26A, 26B, 26C (FIG. 1). Of course, a plurality of operation panels may be installed in a place away from the landing, such as a building entrance or passage. Even in this case, by performing the control of the destination floor registration in the plurality of operation panels installed on the same floor independently of each other, it is possible to control the destination floor registration of the car as in the above embodiment. is there.
