Description

この発明は、エレベータドアに人の手などが引き込まれることを防止するエレベータドア引き込まれ警報装置に関する。   The present invention relates to an elevator door retracted alarm device that prevents a human hand or the like from being pulled into an elevator door.

エレベータの戸が開くとき、乗客が開く戸に手を付けたままでいると、戸と出入口柱の間または2枚戸片開きドアや4枚戸中央開きドアの高速の戸と低速の戸の間に、手などが引き込まれる可能性があった。そこで、マルチビームセンサにより構成される引き込まれ検知センサを出入口に設置し、乗客が戸の近くにいることを検知して、戸開動作を開始する時点を遅らせたり、警報をアナウンスしたりしてから戸を開くことが提案されている(例えば、特許文献1参照)。   When the elevator door opens, if the passenger keeps a hand on the door that opens, between the door and the entrance pillar or between the high-speed door and the low-speed door of the two-door single door or the four-door central door In addition, there was a possibility that hands were drawn. Therefore, a pull-in detection sensor composed of a multi-beam sensor is installed at the entrance, detects that the passenger is near the door, delays the time to start the door opening operation, or announces an alarm Has been proposed to open the door (see, for example, Patent Document 1).

特開2005−280900号公報JP 2005-280900 A

しかし、かご戸のかご側と乗場戸の乗場側にそれぞれ引き込まれ検知センサが配置されているとき、三方枠の枠幅が小さい場合や出入口の幅が大きい場合には、かご戸および乗場戸が開けられる途中において、一方の引き込まれ検知センサからのビームが他方の引き込まれ検知センサで感知されてしまうという問題がある。
また、この引き込まれ検知センサを戸閉動作時にも人を検出できるようにし、人を検出したとき戸の動作を戸閉動作から戸開動作に反転させるように構成した場合、正常であれば引き込まれ検知センサのビームを人が遮ることにより戸の動作が反転するが、人によって遮られたビームと異なるビームを引き込まれ検知センサが感知してしまうので、引き込まれ検知センサが人の通過を検出することができず、人がかご戸または乗場戸に衝突してしまうという問題がある。
However, when the detection sensors are placed on the car side of the car door and the landing side of the landing door, respectively, if the frame width of the three-way frame is small or the width of the doorway is large, the car door and the landing door In the middle of opening, there is a problem that the beam from one of the detection sensors is pulled in and is detected by the other detection sensor.
In addition, when this pull-in detection sensor is configured to detect a person even when the door is closed, and when the person detects a person, the door movement is reversed from the door closing movement to the door opening movement. If the detection sensor beam is blocked by a person, the movement of the door is reversed, but a beam different from the beam blocked by the person is pulled in and the detection sensor senses it, so the detection sensor detects that the person has passed. There is a problem that people cannot collide with the car door or the landing door.

また、既設のエレベータではドアまわりの安全性を向上するために、戸閉動作中に出入口を通過する乗客を検出するための戸閉センサを設置している場合が多い。この既設のエレベータに引き込まれ検知センサを併設すると、戸閉センサの誤動作を起こしてしまうという問題がある。   In addition, in order to improve the safety around the door, the existing elevator often has a door closing sensor for detecting passengers passing through the doorway during the door closing operation. If a detection sensor is installed in the existing elevator, there is a problem that the door closing sensor malfunctions.

この発明の目的は、閉じる途中の戸に乗客が衝突しないように設置された戸閉センサの誤動作を防止できる人の手などの引き込まれを防ぐエレベータドア引き込まれ警報装置を提供することである。   An object of the present invention is to provide an elevator door retracted alarm device that prevents a person's hand or the like from being pulled in, which can prevent a malfunction of a door closing sensor installed so that passengers do not collide with a door in the middle of closing.

この発明に係わるエレベータドア引き込まれ警報装置は、エレベータかごの出入口をかご戸のかご室側の表面に沿って横切るように投光するビームが上記かご戸に触れる人により遮られることを検知するかご側引き込まれ検知センサまたは乗場の出入口を乗場戸の乗場側の表面に沿って横切るように投光するビームが上記乗場戸に触れる人により遮られることを検知する乗場側引き込まれ検知センサの少なくともいずれか一方を備えるエレベータドア引き込まれ警報装置において、上記かご側引き込まれ検知センサと上記乗場側引き込まれ検知センサは、上記かご戸および上記乗場戸が全閉状態のときだけ、触れる人を検知する。   The elevator door retracted alarm device according to the present invention is a car that detects that the beam projected to cross the elevator car entrance and exit along the car room side surface is blocked by a person touching the car door. At least one of a side-drawn detection sensor and a landing-side detection sensor that detects that a beam projecting across the entrance / exit of the landing along the landing-side surface of the landing door is blocked by a person touching the landing door In the elevator door pull-in alarm device including either of the above, the car-side pull-in detection sensor and the landing-side pull-in detection sensor detect a touching person only when the car door and the landing door are in a fully closed state.

この発明に係わるエレベータドア引き込まれ警報装置の効果は、戸閉センサが既設のエレベータにかご側引き込まれ検知センサまたは乗場側引き込まれ検知センサの少なくともいずれか一方を備えても、かご側引き込まれ検知センサと乗場側引き込まれ検知センサとがかご戸および乗場戸が全閉状態のときだけそれらの戸に触れる人を検知するので、戸閉センサとかご側引き込まれ検知センサおよび乗場側引き込まれ検知センサが干渉して戸閉センサが誤動作することを防げる。引き込まれ検知センサを配置既設の戸閉センサに乗場側のマルチビームセンサの受光器に、かご側のマルチビームセンサのビームが入り込み、乗場側のマルチビームセンサの戸閉方向での人の検出に誤動作を発生させることを防止することができる。   The effect of the elevator door retracted alarm device according to the present invention is that, even if the door closing sensor is pulled into the existing elevator and the at least one of the detection sensor or the landing side pulled in detection sensor is provided, the car side pulled in detection is detected. Since the sensor and the landing side pull-in detection sensor detect the car door and the person touching the door only when the landing door is fully closed, the door closing sensor and the car side pulling detection sensor and the landing side pulling detection sensor Prevents the door closing sensor from malfunctioning due to interference. Pulled-in detection sensor installed The beam of the multi-beam sensor on the car side enters the receiver of the multi-beam sensor on the landing side into the existing door-closing sensor, and detects the person in the door closing direction of the multi-beam sensor on the landing side It is possible to prevent a malfunction from occurring.

This is a device that issues an alarm by detecting whether or not a human hand is touching or approaching the car door 13 or the landing door 23.
Therefore, the elevator according to the present invention will be briefly described. As shown in FIG. 1, the elevator moves up and down the elevator car 1 that moves up and down in the hoistway, the hall 2 provided on each floor where passengers get on and off, and the elevator car 1. A car drive device 3, a car door 13 provided at the entrance / exit of the elevator car 1, a landing door 23 provided at the entrance / exit of each landing 2, a door drive device 4 for opening / closing the car door 13, and a position sensor for detecting the position of the elevator car 1 5 and an elevator control device 6 for controlling the entire elevator.

次に、かご戸13および乗場戸23について詳しく図1、図2を参照して説明する。
かご戸13は、エレベータかご1の出入口柱12により挟まれた出入口を開閉し、エレベータかご1の上部に設置する戸駆動装置4の図示しないドアモータにより開閉される。
乗場戸23は、各階床の乗場2の三方枠21に囲まれた出入口を開閉し、かご戸13と図示しない係合装置によって係合して、かご戸13の開閉に連動して開閉され、かご室11に乗客が乗降することができるようにする。
乗場戸23は、かご戸13に係合されて開き始める。開き始めのわずかの動きで、図示しない係合装置の図示しない可動ベーンが乗場2の図示しない乗場の錠ラッチに連動している図示しない係合ローラを押して乗場の錠を外して乗場戸23が開くことが可能になって戸開きする。
Next, the car door 13 and the landing door 23 will be described in detail with reference to FIGS.
The car door 13 opens and closes an entrance / exit sandwiched by the entrance / exit pillars 12 of the elevator car 1, and is opened / closed by a door motor (not shown) of the door driving device 4 installed on the upper part of the elevator car 1.
The landing door 23 opens and closes the doorway surrounded by the three-way frame 21 of the landing 2 on each floor, engages with the car door 13 by an engagement device (not shown), and is opened and closed in conjunction with the opening and closing of the car door 13. Passengers can get in and out of the cab 11.
The landing door 23 is engaged with the car door 13 and starts to open. With a slight movement at the beginning of opening, a movable vane (not shown) of an engagement device (not shown) pushes an engagement roller (not shown) interlocked with a lock latch of a hall (not shown) of the hall 2 to unlock the hall and the landing door 23 It becomes possible to open and opens the door.

かご戸13と乗場戸23の間に、エレベータを乗降する乗客が戸閉動作中のかご戸13に衝突することを未然に防止する目的で、かご側戸閉センサ15が配置されている。かご側戸閉センサ15は、一方のかご戸13と対面する一方の乗場戸23の間に設置する投光器15aと、他方のかご戸13と対面する他方の乗場戸23の間に設置する受光器15bを備える。そして、投光器15aから出入口の上から下まで全域に亘って横方向に横切るビーム15cが投光されている。この投光器15aから投光されるビーム15cが遮られたとき、かご戸13の動作を戸開動作に反転する。   A car side door closing sensor 15 is arranged between the car door 13 and the landing door 23 in order to prevent a passenger who gets on and off the elevator from colliding with the car door 13 during the door closing operation. The car-side door closing sensor 15 is a light receiver that is installed between a projector 15a that is installed between one landing door 23 that faces one of the car doors 13 and another landing door 23 that faces the other car door 13. 15b. A beam 15c is projected across the entire region from the projector 15a to the bottom of the entrance and exit. When the beam 15c projected from the projector 15a is blocked, the operation of the car door 13 is reversed to the door opening operation.

戸駆動装置4は、戸開指令信号が入力されるとかご戸13を開き、戸閉指令信号が入力されるとかご戸13を閉じる。また、かご戸13および乗場戸23が全開状態になると全開完了信号、かご戸13および乗場戸23が全閉状態になると全閉完了信号を出力する。   The door driving device 4 opens the car door 13 when a door opening command signal is input, and closes the car door 13 when a door closing command signal is input. Further, when the car door 13 and the landing door 23 are fully opened, a fully open completion signal is output, and when the car door 13 and the landing door 23 are fully closed, a fully closed completion signal is output.

次に、この発明に係わるエレベータドア引き込まれ警報装置の構成について、図1と図2を参照して説明する。
エレベータドア引き込まれ警報装置は、かご側引き込まれ検知センサ14、乗場側引き込まれ検知センサ24、かご側警報装置16、乗場側警報装置25、引き込まれ制御装置7を備える。
かご側引き込まれ検知センサ14は、かご室11内の乗客がかご戸13に手などが触れていると、エレベータかご1が行先階の階床の乗場2に着床決定してからかご戸13が開き始めるまでの間、かご戸13と出入口柱12との間に手などが引き込まれることを未然に防止するため、乗客の手などを検知する。そして、かご側引き込まれ検知センサ14は、マルチビームセンサから構成されている。
Next, the construction of the alarm device for retracting the elevator door according to the present invention will be described with reference to FIGS.
The elevator door retracted alarm device includes a car-side retracted detection sensor 14, a landing-side retracted detection sensor 24, a car-side alarm device 16, a landing-side alarm device 25, and a retracted control device 7.
When the passenger in the car room 11 touches the car door 13 with a hand or the like, the car side pull-in detection sensor 14 detects the car door 13 after the elevator car 1 decides to land on the landing 2 on the floor of the destination floor. In order to prevent a hand or the like from being drawn between the car door 13 and the doorway pillar 12 until the door starts to open, the passenger's hand or the like is detected. The car-side retracted detection sensor 14 is composed of a multi-beam sensor.

このかご側引き込まれ検知センサ14は、出入口の一方の側に配置される出入口柱12とかご戸13の間に設置する投光器14aと、出入口の他方の側に配置される出入口柱12とかご戸13の間に設置する受光器14bを備える。そして、投光器14aから出入口の上から下まで全域に亘って横方向に横切るビーム14cが投光されている。そして、かご戸13に触れる人の手などがビーム14cを遮ることにより、人の手などを検知することができる。   The car-side detection sensor 14 includes a floodlight 14a installed between the entrance / exit post 12 and the car door 13 disposed on one side of the entrance / exit, and the entrance / exit post 12 and the car door disposed on the other side of the entrance / exit. 13 is provided. And the beam 14c which crosses a horizontal direction is projected over the whole region from the projector 14a to the bottom of the entrance / exit. A person's hand or the like touching the car door 13 can detect the person's hand or the like by blocking the beam 14c.

また、ビーム14cは、水平に対して約15度拡がりを有しているので、投光器14aと受光器14bの光軸がずれていてもかご戸13に触れる人の手などを検出することができる。
また、かご側引き込まれ検知センサ14は、近くにかご側戸閉センサ15が配置されており、かご側引き込まれ検知センサ14の受光器14bがかご側戸閉センサ15の投光器15aからのビームを受光しないように、ビームの進む方向を反対にしてある。
Further, since the beam 14c is expanded by about 15 degrees with respect to the horizontal, even if the optical axes of the light projector 14a and the light receiver 14b are shifted, it is possible to detect the hand of a person touching the car door 13 and the like. .
In addition, the car-side drawn-in detection sensor 14 has a car-side door closing sensor 15 disposed nearby, and the light-receiving device 14b of the car-side drawn-in detection sensor 14 receives the beam from the projector 15a of the car-side door closed sensor 15. In order not to receive light, the traveling direction of the beam is reversed.

かご側警報装置16は、かご戸13が全閉の状態でエレベータかご1が行先階の乗場2に着床しようと決定するときから、かご戸13が開く動作を開始するときまでの間で、かご側引き込まれセンサ14が乗客の手などを検知したとき、警報を発する。   The car-side alarm device 16 is in a period from when the elevator car 1 decides to land on the landing 2 on the destination floor with the car door 13 fully closed until the time when the car door 13 starts to open. When the car is pulled in and the sensor 14 detects a passenger's hand, an alarm is issued.

乗場側引き込まれ検知センサ24は、マルチビームセンサから構成され、一方の縦枠の乗場側に設置する投光器24aと他方の縦枠の乗場側に設置する受光器24bを備える。この投光器24aと受光器24bは、直接外力が加わって破損しないように図示しないカバーで保護している。そして、投光器24aから三方枠21の上から下まで全域に亘って横方向に横切るビーム24cが投光されている。   The landing-side drawn-in detection sensor 24 includes a multi-beam sensor, and includes a projector 24a installed on the landing side of one vertical frame and a light receiver 24b installed on the landing side of the other vertical frame. The projector 24a and the light receiver 24b are protected by a cover (not shown) so as not to be directly damaged by external force. A beam 24c is projected across the entire region from the projector 24a to the bottom of the three-way frame 21 in the horizontal direction.

乗場側警報装置25は、エレベータかご1が行先階の乗場2に着床して、乗場戸23が戸開するときに乗場戸23に乗客の手などが触れているとき、乗場戸23が開く動作をすることにより三方枠21と乗場戸23の間に手などが引き込まれてしまうことを未然に防止するための警報装置である。受光器24bの全体を覆うカバーの中に小形のスピーカなどで構成されている。   The landing side alarm device 25 opens the landing door 23 when the elevator car 1 touches the landing door 23 when the elevator car 1 reaches the landing 2 on the destination floor and the landing door 23 opens. This is an alarm device for preventing a hand from being drawn between the three-way frame 21 and the landing door 23 by operating. A cover that covers the entire light receiver 24b is configured with a small speaker or the like.

ステップS11で、引き込まれ制御装置7は、戸閉完了信号を受信したらかご側引き込まれ検知センサ14および乗場側引き込まれ検知センサ24のビームを投光し、人の手などを検知する機能を有効化する。この状態は図2に示す。
In step S9, the retracted controller 7 starts a timer counting from the reception of the door open completion signal, sends a door closing command after the lapse only non-interfering time T 2 to the door driver 4, accordingly, the door The driving device 4 starts to close the car door 13, and the landing door 23 starts to close in conjunction with the driving.
In step S10, the controller 7 is drawn to determine whether or not a door closing completion signal has been received. When the door closing completion signal is received, the process proceeds to step S11. When the door closing completion signal has not been received, step S10 is executed. repeat.
In step S11, the controller 7 is pulled in and the control device 7 activates the function of detecting a person's hand and the like by projecting the car-side pull-in detection sensor 14 and the landing-side pull-in detection sensor 24 when receiving the door closing completion signal. Turn into. This state is shown in FIG.

このように、行先階に停止し、かご戸13および乗場戸23の戸開動作を開始するときに、人の手などがかご戸13または乗場戸23に触れているまたは近接していると警報がアナウンスされ、遅延時間Tだけ戸開動作を開始する時点を遅らすので、人の手などが引き込まれることを防ぐことができる。 As described above, when stopping at the destination floor and starting the door opening operation of the car door 13 and the landing door 23, a warning is given if a human hand is touching or approaching the car door 13 or the landing door 23. There is announced, because delay the time of starting the only door-opening operation delay time T 1, it is possible to prevent the like human hand is drawn.

なお、上述した引き込まれ制御装置7の動作は、エレベータかご1が走行中にある場合であるが、エレベータかご1がN階に停止している状態で行先階登録が有る場合には、かご戸13および乗場戸23が全閉状態で、かご側引き込まれ検知センサ14および乗場側引き込まれ検知センサ24の人の手などを検知する機能が有効になったまま、エレベータかご1が行先階に走行される。そして、図3のステップS1から引き込まれ制御装置7の動作が開始される。
また、エレベータかご1がN階に停止している状態で停止している階以外の階の乗場呼びがある場合も、かご戸13および乗場戸23が全閉状態で、かご側引き込まれ検知センサ14および乗場側引き込まれ検知センサ24の人の手などを検知する機能が有効になったまま、エレベータかご1が乗場呼びのあった階に走行される。そして、図3のステップS1から引き込まれ制御装置7の動作が開始される。
The above-described operation of the drawn-in control device 7 is performed when the elevator car 1 is running, but when the elevator car 1 is stopped on the Nth floor and there is a destination floor registration, the car door 13 and the landing door 23 are fully closed, and the elevator car 1 travels to the destination floor with the function of detecting the hand of the detection sensor 14 and the detection sensor 24 pulled in the car side enabled. Is done. And it pulls in from step S1 of FIG. 3, and the operation | movement of the control apparatus 7 is started.
In addition, even when there is a hall call on a floor other than the floor where the elevator car 1 is stopped on the Nth floor, the car door 13 and the landing door 23 are fully closed, and the car side is pulled in. 14, the elevator car 1 is driven to the floor where the hall call was made, with the function of detecting the hand of the detection sensor 24 being pulled in and the landing side 24 enabled. And it pulls in from step S1 of FIG. 3, and the operation | movement of the control apparatus 7 is started.

一方、エレベータかご1がN階に停止している状態で停止しているN階の乗場呼びが有るときには、かご戸13および乗場戸23が全閉状態にあり、かご側引き込まれ検知センサ14および乗場側引き込まれ検知センサ24の人の手などを検知する機能が有効になっており、図3のステップS2から引き込まれ制御装置7の動作が開始される。   On the other hand, when the elevator car 1 is stopped on the Nth floor and there is a stop calling on the Nth floor, the car door 13 and the landing door 23 are in a fully closed state, the car side is pulled in, and the detection sensor 14 and The function of detecting the person's hand or the like of the landing side withdrawn detection sensor 24 is effective, and the operation of the control device 7 is started by being pulled in from step S2 in FIG.

次に、この発明に係わるエレベータドア引き込まれ警報装置の効果について説明する。 もし、戸開動作中に亘ってかご側引き込まれ検知センサ14および乗場側引き込まれ検知センサ24の人の手などを検知する機能を有効のままにしておくと、投光器24aからのビーム24cが受光器14bに入射してしまい、人が出入口を通過していて、ビーム14cを遮断し、戸が反転して戸開してくれるものと期待していると、ビーム24cの誤動作により戸閉動作中に反転せずに乗客に衝突してしまう可能性があった。
しかし、図3のステップS6で戸開動作を開始するとステップS7でかご側引き込まれ検知センサ14および乗場側引き込まれ検知センサ24のビームを遮断し、且つ受光器14b、24bを停止して人の手などを検知する機能を無効化しているので、誤動作の危険を未然に防止することができる。
Next, the effect of the alarm device that is drawn into the elevator door according to the present invention will be described. If the function of detecting the hand of the car-side detection sensor 14 and the landing-side detection sensor 24 is detected while the door is open, the beam 24c from the projector 24a is received. If it is incident on the vessel 14b and a person is passing through the entrance and exits the beam 14c and expects the door to reverse and open, the door 24 is being closed due to a malfunction of the beam 24c. There was a possibility of colliding with passengers without reversing.
However, when the door opening operation is started in step S6 of FIG. 3, in step S7, the car is pulled in and the detection sensor 14 and the landing side are pulled out, the beams of the detection sensor 24 are cut off, and the light receivers 14b and 24b are stopped to Since the function for detecting a hand or the like is disabled, the risk of malfunction can be prevented.

また、かご側引き込まれ検知センサ14および乗場側引き込まれ検知センサ24の人の手などを検知する機能を戸閉動作中に有効にしていると、投光器15aからのビーム15cが受光器24bに入射して乗場側引き込まれ検知センサ24を誤動作する可能性があったが、図3のステップS6で戸開動作を開始するとステップS7でかご側引き込まれ検知センサ14および乗場側引き込まれ検知センサ24のビームを遮断して、人の手などを検知する機能を無効化しているので、誤動作の危険を未然に防止することができる。   Further, if the function of detecting the hand of the car-side detection sensor 14 and the landing-side detection sensor 24 is enabled during the door closing operation, the beam 15c from the projector 15a enters the light receiver 24b. Then, there is a possibility that the landing side is pulled in and the detection sensor 24 malfunctions. However, when the door opening operation is started in step S6 in FIG. 3, the car side is pulled in in step S7 and the landing side detection sensor 24 Since the function of detecting a human hand or the like is disabled by blocking the beam, the risk of malfunction can be prevented in advance.

また、図2のように乗場側引き込まれ検知センサ24を乗客が多い階だけに設置し、図5に示すようにその他の階に設置しない場合がある。この場合には、設置した階の乗場側引き込まれ検知センサ24は、戸閉方向には無効である。もし、戸閉方向に有効にしていると、乗場側引き込まれ検知センサ24を設置した階で、乗客が出入口を通過中に乗場側引き込まれ検知センサ24のビーム24cを遮るので、戸閉動作中の乗場戸23が反転する。乗客は乗場側引き込まれ検知センサ24の設置してない階でも、乗場戸23が反転動作すると勘違いして戸閉動作中の乗場戸23に衝突する可能性があった。
しかし、戸が開いたときには乗場側引き込まれ検知センサ24の人の手などを検知する機能を無効にしているので、乗場側引き込まれ検知センサ24が設置された階でも、戸が反転しないために、乗場側引き込まれ検知センサ24が設置されていない階で乗客が勘違いして、戸閉動作中の出入口に突入することがなく、勘違いによる戸との衝突を防止することができる。
Further, there are cases where the landing side drawn-in detection sensor 24 is installed only on the floor where there are many passengers as shown in FIG. 2 and not installed on other floors as shown in FIG. In this case, the landing-side landing-side detection sensor 24 of the installed floor is invalid in the door closing direction. If it is enabled in the door closing direction, the passenger is drawn in while passing through the entrance and shuts off the beam 24c of the detection sensor 24 at the floor where the landing sensor is pulled in and the detection sensor 24 is installed. The platform door 23 is inverted. Even if the passenger is pulled in at the landing side and the detection sensor 24 is not installed, there is a possibility that the passenger will mistakenly collide with the landing door 23 during the door closing operation when the landing door 23 is reversed.
However, when the door is opened, the landing side is pulled in and the function of detecting the human hand of the detection sensor 24 is disabled. Therefore, the door is not reversed even on the floor where the landing side is pulled in and the detection sensor 24 is installed. The passenger is mistaken on the floor where the detection sensor 24 is pulled in at the landing side and does not enter the doorway during the door closing operation, thereby preventing a collision with the door due to the mistake.

また、かご側戸閉センサ15の代わりに光電装置を2セット、投光部と受光部とを逆向きにしてかご戸13に設置する場合があり、その場合、光の広がりがあるために、2セットのビームの向きを同じ向きにすると、上側の投光部のビームを下側の受光部が受けて誤動作しないように、ビームの向きを逆にしている。
この場合には、ビームの広がり仰角が、かご側戸閉センサ15よりも大きいため、かご側引き込まれ検知センサ14、乗場側引き込まれ検知センサ24の誤動作を引き起こす可能性が高い。
しかし、戸が開いたときにはかご側引き込まれ検知センサ14および乗場側引き込まれ検知センサ24の人の手などを検知する機能を無効にしているので、それぞれが誤動作することを未然に防止することができる。
Moreover, instead of the car side door closing sensor 15, there are two sets of photoelectric devices, and the light projecting unit and the light receiving unit may be installed in the car door 13 in opposite directions. If the two sets of beams are directed in the same direction, the beams are reversed so that the lower light receiving unit receives the beam from the upper light projecting unit and does not malfunction.
In this case, since the divergence elevation angle of the beam is larger than that of the car-side door closing sensor 15, there is a high possibility that the car-side pull-in detection sensor 14 and the landing-side pull-in detection sensor 24 will malfunction.
However, when the door is opened, the car-side detection sensor 14 and the landing-side detection sensor 24 function of detecting a human hand or the like is disabled, so that each malfunction can be prevented in advance. it can.
