そして、図６に示されるように、第１ケーブル４３ａが電気配線４４ａ，４４ｂにより構成されている。そして、電気配線４４ａ，４４ｂの一端（第１ケーブル４３ａの一端）が投光ユニット３２Ａに接続され、電気配線４４ａの他端がエレベータ制御盤３８に接続され、電気配線４４ｂの他端が電源４８に接続されている。   And as FIG. 6 shows, the 1st cable 43a is comprised by electrical wiring 44a, 44b. Then, one end of the electrical wirings 44a and 44b (one end of the first cable 43a) is connected to the light projecting unit 32A, the other end of the electrical wiring 44a is connected to the elevator control panel 38, and the other end of the electrical wiring 44b is the power source 48. It is connected to the.

また、第２ケーブル４３ｂが電気配線４４ｃ，４４ｄにより構成されている。そして、電気配線４４ｃ，４４ｄの一端（第２ケーブル４３ｂの一端）が受光ユニット４０Ａに接続され、電気配線４４ｃの他端がエレベータ制御盤３８に接続され、電気配線４４ｄの他端が電源４８に接続されている。   Further, the second cable 43b is constituted by electric wirings 44c and 44d. Then, one end of the electrical wirings 44c and 44d (one end of the second cable 43b) is connected to the light receiving unit 40A, the other end of the electrical wiring 44c is connected to the elevator control panel 38, and the other end of the electrical wiring 44d is connected to the power source 48. It is connected.

なお、詳細には図示しないが、第１ケーブル４３ａの一端は、縦枠２Ａの上部に位置する上枠２Ｃの部位に形成された挿通穴のそれぞれから縦枠２Ａ内に引き込まれて投光ユニット３２Ａに接続されている。また、第２ケーブル４３ｂの一端は、縦枠２Ｂの上部に位置する上枠２Ｃの部位に形成された挿通穴のそれぞれから縦枠２Ｂ内に引き込まれて受光ユニット４０Ａに接続されている。   Although not shown in detail, one end of the first cable 43a is drawn into the vertical frame 2A from each of the insertion holes formed in the portion of the upper frame 2C located above the vertical frame 2A. 32A. In addition, one end of the second cable 43b is drawn into the vertical frame 2B from each of the insertion holes formed in the portion of the upper frame 2C located above the vertical frame 2B and connected to the light receiving unit 40A.

そして、受光器４１は、受光状態に応じた電気信号を出力している。例えば、受光器４１は、投光器３４からの光を受光しているときに電気的にＨｉｇｈ（ＯＮ）の信号を出力し、投光器３４から投光された光が乗客に遮断されて光を受光しなくなったときに、電気的にＬｏｗ（ＯＦＦ）となる信号を検出信号として出力している。
つまり、三方枠２内に乗客がいるときには、投光器３４から受光器４１へ向かう光の少なくとも一つが当該乗客により遮断され、三方枠２内の乗客の検出信号が光を受光しなくなった受光器４１から出力されてエレベータ制御盤３８に入力される。そして、エレベータ制御盤３８は、検出信号が入力されたときに、乗客が三方枠２内にいると判断するようになっている。 The light receiver 41 outputs an electrical signal corresponding to the light receiving state. For example, the light receiver 41 electrically outputs a High (ON) signal while receiving light from the projector 34, and the light projected from the projector 34 is blocked by the passenger and receives the light. When the signal disappears, a signal that is electrically low (OFF) is output as a detection signal.
That is, when there is a passenger in the three-way frame 2, at least one of the light traveling from the projector 34 to the light receiver 41 is blocked by the passenger, and the receiver 41 in which the detection signal of the passenger in the three-way frame 2 stops receiving light. Is input to the elevator control panel 38. The elevator control panel 38 determines that the passenger is in the three-way frame 2 when the detection signal is input.

また、エレベータ制御盤３８は戸１３を開閉させるためのドアモータ５０に接続され、ドアモータ５０の駆動に連動させて戸１３の開閉を制御することが可能になっている。さらに、エレベータ制御盤３８は、スピーカ１８に接続され、スピーカ１８に任意のアナウンスを行わせることが可能になっている。   The elevator control panel 38 is connected to a door motor 50 for opening and closing the door 13, and can control the opening and closing of the door 13 in conjunction with the drive of the door motor 50. Further, the elevator control panel 38 is connected to the speaker 18 so that the speaker 18 can make an arbitrary announcement.

また、受光ユニット４０Ａの筺体３３ｂが、一対の第１センサ保持材２８の第１保持部２８ｂ及び第２センサ保持材２９の第２保持部２９ｂのそれぞれに挟持されるように、筺体３３ｂと第１保持部２８ｂ及び第２保持部２９ｂとの間を両面テープにより固定する。   Further, the housing 33b and the second housing 33b of the light receiving unit 40A are sandwiched between the first holding portion 28b of the pair of first sensor holding members 28 and the second holding portion 29b of the second sensor holding member 29, respectively. The space between the first holding portion 28b and the second holding portion 29b is fixed with a double-sided tape.

このとき、筺体３３ｂが、第１取付部２８ａ及び第２取付部２９ａ側の端部から突出しないように配置し、かつ、第１取付部２８ａ及び第２取付部２９ａ側に筺体３３ｂの入射壁が配置されるように筺体３３ｂと第１保持部２８ｂ及び第２保持部２９ｂとの間を固定する。   At this time, the housing 33b is disposed so as not to protrude from the end portions on the first mounting portion 28a and the second mounting portion 29a side, and the incident wall of the housing 33b on the first mounting portion 28a and the second mounting portion 29a side. Is fixed between the housing 33b and the first holding part 28b and the second holding part 29b.

そして、筺体３３ｂを挟持する一対の第１取付部２８ａ及び一対の第２取付部２９ａの外面を側壁カバー部２１の裏面に固定し、受光ユニット４０Ａを側壁カバー部２１に支持させる。
次いで、第１ケーブル４３ａと投光ユニット３２Ａとを連結し、第２ケーブル４３ｂの一端と受光ユニット４０Ａとを連結する。また、三方枠２の前面壁部４の表面全域に両面テープを張り付けておく。 Then, the outer surfaces of the pair of first mounting portions 28a and the pair of second mounting portions 29a that sandwich the housing 33b are fixed to the back surface of the side wall cover portion 21, and the light receiving unit 40A is supported by the side wall cover portion 21.
Next, the first cable 43a and the light projecting unit 32A are connected, and one end of the second cable 43b and the light receiving unit 40A are connected. A double-sided tape is attached to the entire surface of the front wall 4 of the three-way frame 2.

そして、投光器３４の投光部と反対側がセンサ配設穴８に収納されるように、かつ、縦枠２Ａの表面がセンサカバー２０Ａで遮蔽されるように、投光ユニット３２Ａを固定したセンサカバー２０Ａを配置する。そして、縦枠２Ａの前面壁部４と前面カバー部２２との間を両面テープにて固定し、背面壁部５と背面カバー部２３との間をねじ３６により締着固定する。   A sensor cover to which the light projecting unit 32A is fixed so that the side opposite to the light projecting portion of the light projector 34 is accommodated in the sensor mounting hole 8 and the surface of the vertical frame 2A is shielded by the sensor cover 20A. 20A is arranged. Then, the front wall portion 4 and the front cover portion 22 of the vertical frame 2 </ b> A are fixed with double-sided tape, and the back wall portion 5 and the rear cover portion 23 are fastened and fixed with screws 36.

また、受光器４１の受光部と反対側がセンサ配設穴８に収納されるように、かつ、縦枠２Ｂの表面がセンサカバー２０Ｂで遮蔽されるように、受光ユニット４０Ａを固定したセンサカバー２０Ｂを配置する。そして、縦枠２Ｂの前面壁部４と前面カバー部２２との間を両面テープにて固定し、背面壁部５と背面カバー部２３との間をねじ３６により締着固定する。
これにより、既設の三方枠２を利用したエレベータの出入口装置１Ａの構築が完了する。 Further, the sensor cover 20B to which the light receiving unit 40A is fixed so that the side opposite to the light receiving portion of the light receiver 41 is accommodated in the sensor mounting hole 8 and the surface of the vertical frame 2B is shielded by the sensor cover 20B. Place. Then, the front wall portion 4 and the front cover portion 22 of the vertical frame 2B are fixed with a double-sided tape, and the back wall portion 5 and the rear cover portion 23 are fastened and fixed with screws 36.
This completes the construction of the elevator entrance / exit device 1A using the existing three-way frame 2.

上記のように構成されたエレベータの出入口装置１Ａの動作について説明する。
初期状態は、かご１０が所定の階床に着床する直前の状態にあり、戸１３が全閉されている状態にあるものとする。また、投光器３４からは間口方向に相対する受光器４１に向かって、光が常時投光されているものとする。 The operation of the elevator doorway apparatus 1A configured as described above will be described.
It is assumed that the initial state is a state immediately before the car 10 reaches a predetermined floor and the door 13 is fully closed. In addition, it is assumed that light is constantly projected from the light projector 34 toward the light receiver 41 facing the frontage direction.

エレベータ制御盤３８は、かご１０が所定の階床に着床する直前に、または、所定の階床に着床すると同時に、乗客が三方枠２内にいるか否かを判断する。   The elevator control panel 38 determines whether or not the passenger is in the three-way frame 2 immediately before the car 10 reaches the predetermined floor or at the same time when the car 10 reaches the predetermined floor.

このとき、エレベータ制御盤３８は、乗客が三方枠２内にいないと判断すると、戸１３の開動作を行う。
また、エレベータ制御盤３８は、乗客が三方枠２内にいると判断すると、かご１０が当該乗客のいる階床に着床した場合でも戸１３の開動作をすぐには行わず、例えば、スピーカ１８に「戸１３が開きます。戸１３から離れて下さい」などの内容を報知させて、戸１３が開動作することを乗客に認知させる。 At this time, if the elevator control panel 38 determines that the passenger is not in the three-way frame 2, the elevator control panel 38 opens the door 13.
Further, when the elevator control panel 38 determines that the passenger is in the three-way frame 2, the elevator control panel 38 does not immediately open the door 13 even when the car 10 reaches the floor where the passenger is located. 18 is informed of the contents such as “door 13 opens. Please move away from door 13” to let the passenger recognize that door 13 is opening.

そして、エレベータ制御盤３８は、所定時間（例えば、５秒）経過後、乗客が三方枠２内にいるか否かを再度判断し、乗客が三方枠２内にいないと判断すると、戸１３を開動作させる。なお、エレベータ制御盤３８は、乗客が三方枠２内にとどまったままであると判断した場合には、スピーカ１８からブザー音を流すとともに、再度、「戸１３が開きます。戸１３から離れて下さい」などの内容を報知させ、戸１３が開動作することを乗客に確実に認知させて乗客を三方枠２外に移動させた後、戸１３を開動作させる。   Then, after a predetermined time (for example, 5 seconds) has elapsed, the elevator control panel 38 determines again whether or not the passenger is in the three-way frame 2, and if it is determined that the passenger is not in the three-way frame 2, the door 13 is opened. Make it work. If the elevator control panel 38 determines that the passenger remains in the three-way frame 2, the elevator control panel 38 emits a buzzer sound from the speaker 18 and again “Door 13 opens. Please move away from Door 13. , Etc., the passenger 13 is surely recognized that the door 13 is opened, and the passenger is moved out of the three-way frame 2, and then the door 13 is opened.

また、戸１３が全開された後、図示しないかご操作盤の戸閉ボタンが操作されるか、または戸閉および戸開ボタンが操作されないまま所定時間経過すると、エレベータ制御盤３８は、乗客が三方枠２内にいるか否かを判断する。
そして、エレベータ制御盤３８は、乗客が三方枠２内にいないと判断すると戸１３を閉動作させる。
また、エレベータ制御盤３８は、乗客が三方枠２内にいると判断すると、例えば、スピーカ１８に「戸１３が閉まります。戸１３から離れて下さい」などの内容を報知させて、戸１３が閉動作することを乗客に認知させる。 In addition, after the door 13 is fully opened, when a door closing button of a car operation panel (not shown) is operated, or when a predetermined time elapses without the door closing and door opening buttons being operated, the elevator control panel 38 causes the passenger to It is determined whether or not the frame 2 exists.
When the elevator control panel 38 determines that the passenger is not in the three-way frame 2, the elevator control panel 38 closes the door 13.
When the elevator control panel 38 determines that the passenger is in the three-way frame 2, for example, the elevator control panel 38 informs the speaker 18 of a content such as “Door 13 is closed. Let the passenger know that it is closing.

そして、エレベータ制御盤３８は、所定時間（例えば、５秒）経過後、乗客が三方枠２内にいるか否かを再度判断し、乗客が三方枠２内からいなくなったと判断すると、戸１３を閉動作させる。なお、エレベータ制御盤３８は、乗客が三方枠２内にとどまったままであると判断した場合には、スピーカ１８からブザー音を流すとともに、再度、「戸１３が閉まります。戸１３から離れて下さい」などの内容を報知させて、戸１３が閉動作することを乗客に確実に認知させ、乗客を三方枠２外に移動させた後、戸１３を動作させる。   Then, the elevator control panel 38 determines again whether or not the passenger is in the three-way frame 2 after a predetermined time (for example, 5 seconds) has elapsed, and determines that the passenger is no longer in the three-way frame 2. Close operation. If the elevator control panel 38 determines that the passenger remains in the three-way frame 2, the elevator control panel 38 emits a buzzer sound from the speaker 18 and again “Door 13 closes. , Etc., the passenger 13 is surely recognized that the door 13 is closing, and after the passenger is moved out of the three-way frame 2, the door 13 is operated.

この実施の形態１によれば、乗客検出センサ３１Ａが、投光器３４が所定方向に複数配列された投光ユニット３２Ａ及び受光器４１が所定方向に複数配列された受光ユニット４０Ａを、投光器３４及び受光器４１の配列方向を高さ方向に一致させ、投光器３４及び受光器４１が一対一で対をなすように一対の側壁部３の一方及び他方の側にわけて配置して構成されている。このとき、投光器３４及び受光器４１の対は、一対の側壁部３の相対する壁面間で光を送受可能に配置されている。   According to the first embodiment, the passenger detection sensor 31A includes the light projector unit 32A in which a plurality of light projectors 34 are arranged in a predetermined direction and the light receiving unit 40A in which a plurality of light receivers 41 are arranged in a predetermined direction. The arrangement direction of the devices 41 is aligned with the height direction, and the projector 34 and the light receiver 41 are arranged separately on one side and the other side of the pair of side wall portions 3 so as to form a pair. At this time, the pair of the projector 34 and the light receiver 41 is arranged so that light can be transmitted and received between the opposing wall surfaces of the pair of side wall portions 3.

そして、乗客が三方枠２内にいるときには、投光器３４が投光した光が乗客により遮られ、検出信号が受光器４１から出力されるようになっている。従って、エレベータ制御盤３８は、受光器４１の検出出力に基づいて三方枠２内に乗客がいることを判断できる。   When the passenger is in the three-way frame 2, the light projected by the projector 34 is blocked by the passenger, and a detection signal is output from the light receiver 41. Therefore, the elevator control panel 38 can determine that there is a passenger in the three-way frame 2 based on the detection output of the light receiver 41.

そして、エレベータ制御盤３８は、戸１３が全閉状態にあるとき、三方枠２内に乗客がいると判断すると、乗客が三方枠２内にいなくなるまで、戸１３の開動作を行わないように戸１３の開閉動作を制御している。
これにより、三方枠２内の乗客の荷物などが、戸１３と三方枠２の間に挟まることを未然に防止できる。 When the elevator control panel 38 determines that there is a passenger in the three-way frame 2 when the door 13 is in the fully closed state, the elevator control panel 38 does not open the door 13 until the passenger is no longer in the three-way frame 2. The door 13 is controlled to open and close.
Thereby, it is possible to prevent a passenger's luggage in the three-way frame 2 from being sandwiched between the door 13 and the three-way frame 2.

さらに、エレベータ制御盤３８は、戸１３が全開状態にあるとき、三方枠２内に乗客がいると判断すると、乗客が三方枠２内にいなくなるまで、戸１３の閉動作を行わないように戸１３の開閉動作を制御している。
これにより、三方枠２内の乗客の荷物などが、戸１３に挟まることを未然に防止できる。 Furthermore, when the elevator control panel 38 determines that there are passengers in the three-way frame 2 when the door 13 is in the fully open state, the elevator control panel 38 does not close the door 13 until the passengers are no longer in the three-way frame 2. The opening / closing operation of the door 13 is controlled.
Thereby, it is possible to prevent a passenger's luggage in the three-way frame 2 from being caught between the doors 13.

また、センサカバー２０Ａ，２０Ｂは、対をなす投光器３４及び受光器４１の間の光路を確保しつつ、投光ユニット３２Ａの投光器３４及び受光ユニット４０Ａの受光器４１を遮蔽するように縦枠２Ａ，２Ｂのそれぞれに取り付けられているので、投光器３４及び受光器４１が損傷することを防止できる。   The sensor covers 20A and 20B have a vertical frame 2A so as to shield the light projector 34 of the light projecting unit 32A and the light receiver 41 of the light receiving unit 40A while securing an optical path between the pair of light projector 34 and light receiver 41. , 2B, the projector 34 and the light receiver 41 can be prevented from being damaged.

さらに、センサ配設穴８が上記間口方向に相対するように一対の側壁部３のそれぞれに形成され、投光ユニット３２Ａの筺体３３ａは、投光器３４の投光部と反対側がセンサ配設穴８を介して縦枠２Ａ内に収納されるように配置され、また、受光ユニット４０Ａの筺体３３ｂは、受光器４１の受光部と反対側がセンサ配設穴８を介して縦枠２Ｂ内に収納されるように配置されている。これにより、筺体３３ａ及び筺体３３ｂを、側壁部３から乗場出入口１６の間口方向の中央側に大きく突出させることなく、投光ユニット３２Ａ及び受光ユニット４０Ａを配設できる。つまり、既設の三方枠２を利用してエレベータの出入口装置１Ａを構築する場合でも、乗場出入口１６の間口方向の幅を狭めることなく出入口装置１Ａを構築できる。   Further, the sensor arrangement hole 8 is formed in each of the pair of side wall portions 3 so as to face the frontage direction, and the housing 33a of the light projecting unit 32A has the sensor arrangement hole 8 on the side opposite to the light projection unit of the light projector 34. The housing 33b of the light receiving unit 40A is housed in the vertical frame 2B through the sensor mounting hole 8 on the side opposite to the light receiving portion of the light receiving unit 41. It is arranged so that. Thereby, the light projecting unit 32A and the light receiving unit 40A can be disposed without causing the housing 33a and the housing 33b to largely protrude from the side wall 3 toward the center of the entrance / exit 16 in the frontage direction. That is, even when the elevator entrance / exit device 1A is constructed using the existing three-way frame 2, the entrance / exit device 1A can be constructed without reducing the width of the entrance / exit 16 in the frontage direction.

また、エレベータ制御盤３８は、戸１３が全閉状態及び全開状態のそれぞれにあるとき、三方枠２内に乗客がいると判断すると、戸１３の開閉動作の開始前、スピーカ１８に戸１３の開動作及び閉動作が開始される内容を報知させている。これにより、乗客がスムーズに三方枠２の外部に移動するので、戸１３の開閉動作が長時間行われないことを回避しつつ、乗客の荷物が三方枠２と戸１３の間、または戸１３の間に挟まることを防止できる。   Further, when the elevator control panel 38 determines that there are passengers in the three-way frame 2 when the door 13 is in the fully closed state and the fully open state, the elevator control panel 38 sets the door 13 to the speaker 18 before starting the opening / closing operation of the door 13. The contents for starting the opening operation and the closing operation are informed. Thus, since the passenger smoothly moves to the outside of the three-way frame 2, the passenger's luggage is placed between the three-way frame 2 and the door 13 or the door 13 while avoiding the door 13 from being opened and closed for a long time. Can be prevented from being pinched between.

また、既設のエレベータの三方枠２を利用してエレベータの出入口装置１Ａを構築する場合、三方枠２にセンサ配設穴８を形成するだけで投光ユニット３２Ａ及び受光ユニット４０Ａの設置スペースを確保できるので、既設のエレベータに対して大規模な改修を行わずに、エレベータ出入口装置１Ａを構築できる。   Further, when the elevator entrance / exit device 1A is constructed using the existing three-way frame 2 of the elevator, the installation space for the light projecting unit 32A and the light receiving unit 40A is ensured only by forming the sensor arrangement hole 8 in the three-way frame 2. Therefore, the elevator entrance / exit device 1A can be constructed without performing a large-scale modification to the existing elevator.

なお、上記実施の形態１では、センサカバー２０Ａ，２０Ｂは、縦枠２Ａ、２Ｂの表面全域を遮蔽するように縦枠２Ａ，２Ｂのそれぞれに固定されるものとして説明したが、センサカバー２０Ａ，２０Ｂは、対をなす投光器３４及び受光器４１の間の光路を確保して投光器３４及び受光器４１を遮蔽するように一対の縦枠２Ａ，２Ｂのそれぞれに配設されていれば、縦枠２Ａ，２Ｂの表面全域を遮蔽するように配設する必要はない。   In the first embodiment, the sensor covers 20A and 20B are described as being fixed to the vertical frames 2A and 2B so as to shield the entire surface of the vertical frames 2A and 2B. If 20B is arranged in each of the pair of vertical frames 2A and 2B so as to secure an optical path between the pair of the projector 34 and the light receiver 41 and shield the projector 34 and the light receiver 41, the vertical frame 20B It is not necessary to arrange so as to shield the entire surface of 2A and 2B.

また、投光ユニット３２Ａ及び受光ユニット４０Ａが、縦枠２Ａ，２Ｂ内に収納可能な大きさであれば、センサカバー２０Ａ，２０Ｂは必ずしも配設しなくてもよい。この場合、投光ユニット３２Ａ及び受光ユニット４０Ａが縦枠２Ａ，２Ｂ内に収納されるように第１保持部２８ｂ及び第２保持部２９ｂの内面を側壁部３の表面に固定して、投光ユニット３２Ａ及び受光ユニット４０Ａを側壁部３に支持させればよい。   Further, if the light projecting unit 32A and the light receiving unit 40A are large enough to be accommodated in the vertical frames 2A and 2B, the sensor covers 20A and 20B are not necessarily provided. In this case, the inner surfaces of the first holding part 28b and the second holding part 29b are fixed to the surface of the side wall part 3 so that the light projecting unit 32A and the light receiving unit 40A are accommodated in the vertical frames 2A and 2B. The unit 32A and the light receiving unit 40A may be supported on the side wall 3.

This completes the construction of the elevator doorway apparatus 1B using the existing three-way frame 2.

なお、上記ように構成されたエレベータの出入口装置１Ｂの動作は上述のエレベータ出入口装置１Ａの動作と同様である。   The operation of the elevator doorway device 1B configured as described above is the same as the operation of the elevator doorway device 1A described above.

この実施の形態２によれば、乗客検出センサ３１Ｂは、一対の側壁部３の相対する壁面間で光を送受可能な投光器３４及び受光器４１の対を複数対有するように、投光ユニット３２Ｂを固定したセンサカバー４５Ａ及び受光ユニット４０Ｂを固定したセンサカバー４５Ｂを一対の縦枠２Ａ，２Ｂの表面の一方及び他方の側にわけて配置したもので構成されている。これにより、三方枠２内の乗客の荷物などが戸１３に挟まることを未然に防止できるとういう実施の形態１と同様の効果に加えて、三方枠２に大きな穴をあけることなくエレベータの出入口装置１Ｂを構成できるという効果が得られる。   According to the second embodiment, the passenger detection sensor 31B has a light projecting unit 32B so as to have a plurality of pairs of light projectors 34 and light receivers 41 capable of transmitting and receiving light between the opposing wall surfaces of the pair of side wall portions 3. The sensor cover 45A to which the light receiving unit 40B is fixed and the sensor cover 45B to which the light receiving unit 40B is fixed are arranged separately on one side and the other side of the surfaces of the pair of vertical frames 2A and 2B. Thus, in addition to the same effect as in the first embodiment that the passenger's luggage in the three-way frame 2 can be prevented from being caught by the door 13, the entrance of the elevator without making a large hole in the three-way frame 2 The effect that the apparatus 1B can be configured is obtained.

なお、上記各実施の形態では、乗客検出センサ３１Ａ，３１Ｂは、投光器３４が複数配列された投光ユニット３２Ａ，３２Ｂ及び受光器４１が複数配列された受光ユニット４０Ａ，４０Ｂにより構成されるものとして説明したが、乗客検出センサは、ユニット化した複数の投光器３４及びユニット化した複数の受光器４１により構成されるものに限定されず、一方及び他方の側壁部３の側にわかれて一対一の対をなすように複数の投光器３４及び受光器４１が個々に配設されたもので構成されているものでもよい。但し、複数の投光器３４及び複数の受光器４１がユニット化された投光ユニット３２Ａ，３２Ｂ及び受光ユニット４０Ａ，４０Ｂを用いれば、複数の投光器３４及び複数の受光器４１を一度に側壁部３に対して配置できるので、エレベータの出入口装置１Ａ，１Ｂを構築するときの時間を短縮できる。   In each of the above embodiments, the passenger detection sensors 31A and 31B are configured by the light projecting units 32A and 32B in which a plurality of light projectors 34 are arranged and the light receiving units 40A and 40B in which a plurality of light receivers 41 are arranged. As described above, the passenger detection sensor is not limited to a unit composed of a plurality of unitized light projectors 34 and a plurality of unitized light receivers 41, and is one-to-one across one and the other side wall 3. A plurality of light projectors 34 and light receivers 41 may be individually arranged so as to form a pair. However, if the light projecting units 32A and 32B and the light receiving units 40A and 40B in which the plurality of light projectors 34 and the plurality of light receivers 41 are unitized are used, the plurality of light projectors 34 and the plurality of light receivers 41 are attached to the side wall 3 at a time. Since it can arrange | position with respect to it, the time at the time of constructing | assembling elevator doorway apparatus 1A, 1B can be shortened.

また、投光器３４及び受光器４１の対の数は、必要に応じて決定すればよく、三方枠２内の乗客を問題なく検出可能であれば一対でもよい。   Further, the number of pairs of the projector 34 and the light receiver 41 may be determined as necessary, and may be a pair as long as the passengers in the three-way frame 2 can be detected without any problem.

また、乗客検出センサ３１Ａ，３１Ｂは、投光器３４及び受光器４１を相対させて配置するものに限定されず、投光器３４から三方枠２内に投光された光の反射光を受光器４１で検知するように投光器３４と受光器４１とを配置して構成してもよい。この場合、受光器４１での反射量の変化をもとに、三方枠２内の乗客を検出することができる。
また、乗客検出センサは三方枠２内の乗客の熱を感知して、三方枠２内の乗客を検出する赤外線センサなどを用いることもできる。
つまり、乗客検出センサの種類は、三方枠２内の乗客を検出可能に三方枠２に配設されているものであれば特に限定されるものではない。 The passenger detection sensors 31A and 31B are not limited to those in which the projector 34 and the light receiver 41 are arranged to face each other, and the reflected light of the light projected from the projector 34 into the three-way frame 2 is detected by the light receiver 41. As described above, the light projector 34 and the light receiver 41 may be arranged. In this case, the passenger in the three-way frame 2 can be detected based on the change in the amount of reflection at the light receiver 41.
The passenger detection sensor may be an infrared sensor or the like that detects the passenger's heat in the three-way frame 2 and detects the passenger in the three-way frame 2.
That is, the type of the passenger detection sensor is not particularly limited as long as it is disposed in the three-way frame 2 so that passengers in the three-way frame 2 can be detected.

また、エレベータ制御盤３８は、戸１３の開閉動作開始時に、乗客が三方枠２内にいると判断すると、戸１３が開閉動作することをスピーカ１８に報知させる制御を行うものとして説明した。
ここで、周知の通り、戸１３の閉方向端部には、乗客の荷物が戸１３に挟まれたことを検出すると作動するセーフティーバー（図示せず）が設置され、エレベータ制御盤３８は、セーフティーバーが作動したと判断すると反転戸開する制御をおこなうように制御する。
従って、戸１３の閉動作時、戸１３が閉動作する内容の報知は、必要に応じて適宜行えばよいが、戸１３の閉動作前に戸１３が閉動作することを乗客に報知させれば、乗客は予め、戸１３が閉まることを認知して三方枠２の外部に移動できるため、乗客に荷物が挟まることによる焦燥感を与えることを未然に回避できる。 Further, the elevator control panel 38 has been described as performing control to notify the speaker 18 that the door 13 is opened and closed when it is determined that the passenger is in the three-way frame 2 at the start of the opening and closing operation of the door 13.
Here, as is well known, a safety bar (not shown) that operates when it is detected that a passenger's baggage is sandwiched between the doors 13 is installed at the end of the door 13 in the closing direction. When it is determined that the safety bar has been activated, control is performed to perform reverse door opening control.
Accordingly, during the closing operation of the door 13, the content of the closing operation of the door 13 may be appropriately performed as necessary, but the passenger can be informed that the door 13 is closing before the closing operation of the door 13. For example, since the passenger can recognize in advance that the door 13 is closed and can move to the outside of the three-way frame 2, it is possible to avoid giving the passenger a feeling of agitation due to the load being caught.
