ご内で長時間待たされることになる。 However, if there are multiple cars waiting with the doors open, it is human nature to want to board, and there is a high possibility that passengers will board even if they are not the first car. Passengers who have boarded the car press the destination button on the in-car control panel to register a car call and wait for departure, but the car will not depart until it is designated as the first car or the car is full, so they cannot board the car. Passengers will have to wait in their cars for a long time.

１台のかごを先発に指定する。先発に指定された
かご２台は戸を開いて乗客の乗り込みを待つこと
になる。手順１３で先発かごに指定すべきかごが
２台あれば、手順１６で余りの１台が帰着階に来
たかを判断し、手順１７で出発階のかご呼びが登
録されていなければ、すなわち出発階で降りる乗
客がいなければ、手順１８でそのかごを戸閉待機
させる。手順１７で出発階のかご呼びが登録され
ていれば、すなわち、出発階で降りる乗客がいれ
ば、手順１０へ戻り、上述と同様の手順をたど

閉待機する（出発階でかご呼びが解除されること
により）。 In step 10, it is determined whether it is time to go to work, and if it is time to go to work, in step 11, the number of passengers waiting at the landing is detected by the device 1.
Depending on the number of customers waiting from
Set. In this case, it is assumed that N=2 is set. The assignment signal 2a to the departure floor is assigned to the number of cars (in this case, 3 cars) to be returned to the departure floor in step 12.
Emits ~2c. In step 13, it is determined whether there are two starting cars. Currently, there is only one car No. 1 on the departure floor, so in step 14 (described in detail in FIG. 3), one car from the starting car is selected from among the cars that have arrived at the departure floor. Then, the other car selected as car No. 1 in step 15 is designated as the starting car. The two cars designated as the first cars will open their doors and wait for passengers to board. If there are two cars that should be designated as the starting car in step 13, it is determined in step 16 whether the remaining car has arrived at the return floor, and if the car call for the departure floor is not registered in step 17, that is, the car is designated as the departure car. If there are no passengers getting off at the floor, the car is placed on standby with the door closed in step 18. If the departure floor car call is registered in step 17, that is, if there are passengers getting off at the departure floor, return to step 10 and follow the same procedure as above to determine whether that car is designated as the first car or not. Or wait with the door closed (as the car call is canceled at the departure floor).

このようにして、出発階には２台のかごが先発
かごとして戸開待機しているので、乗客はどちら
のかごに乗り込んでもやがて出発できることにな
る。 In this way, two cars are waiting with their doors open on the departure floor as the first car, so passengers can depart soon no matter which car they board.

なお、手順１４の先発かごの選択は第３図に示
すとおりである。すなわち、手順２０で２号機が
非先発であるかを判断し、非先発であれば、手順
２１で２号機を先発かごに指定する。２号機が非
先発でなければ、すなわち先発であれば、手順２
２で３号機が非先発であるかを判断し、非先発で
あれば手順２３で３号機を先発かごに指定する。
同様にして手順２４，２５で１号機の選択が行わ
れる。 Note that the selection of the first car in step 14 is as shown in FIG. That is, in step 20 it is determined whether car No. 2 is a non-starter. If it is a non-starter, car No. 2 is designated as the starting car in step 21. If the No. 2 machine is not a non-starter, that is, if it is a starter, proceed to step 2.
In step 2, it is determined whether car No. 3 is a non-starter, and if it is a non-starter, car No. 3 is designated as the starting car in step 23.
Similarly, in steps 24 and 25, the No. 1 car is selected.

このようにして、２台の先発かごが選択される
が、常に前の先発かごと近隣のかごを選択するの
で、積み残される予定の乗客及び乗り遅れた乗客
も隣のかごへ少し移動するだけで、２台目の先発
かごに乗り込むことが可能となる。 In this way, two starting cars are selected, but since the previous starting car and the neighboring car are always selected, passengers who are scheduled to be left behind and passengers who miss the train can also move a little to the next car. , it becomes possible to board the second starting car.

先発かごに指定すべき数Ｎの値は、乗場待客数
検出装置１からの値によつて決めたが、他の群管
理プログラム部分（例えば学習機能を持つプログ
ラム）、建物管理用の電子計算機からの指令、乗
場又は係員管理盤のスイツチ、又は他の先発かご
のかご内負荷が所定値以上になつたときの指令に
より、任意に定めることが可能である。 The value of the number N to be designated for the first car was determined based on the value from the waiting hall number detection device 1, but other parts of the group management program (for example, a program with a learning function), the electronic computer for building management It can be determined arbitrarily by a command from the board, a switch on the landing or staff management panel, or a command when the car load of another car that starts the car exceeds a predetermined value.

以上説明したとおりこの発明では、出発階に帰
着したかごの内出発階の乗場待客数に対応する台
数のかごを先発かごに指定して戸開待機させ、先
発かご以外のかごは戸閉待機させるようにしたの
で、乗場の待客が多い場合でも、過不足のない乗
車率で速やかに処理することができると共に、乗
客は戸の開いているかごに乗りさえすれば、長時
間待たされることなく出発することができる。 As explained above, in this invention, among the cars that have returned to the departure floor, the number of cars corresponding to the number of passengers waiting at the departure floor on the departure floor is designated as the first car and is made to stand by with its doors open, and the cars other than the first car are placed on standby with their doors closed. As a result, even when there are many passengers waiting at the boarding point, the process can be done quickly with just the right occupancy rate, and as long as passengers board a car with an open door, they will not have to wait for a long time. You can leave without leaving.

また、出発階に先発かごが所定の複数台存在し
ないときは、既に指定された先発かごと近隣のか
ごを次の先発かごに指定するようにしたので、積
み残される予定の待客も少し移動するだけで次の
先発かごに容易に乗り込むことができる。 In addition, when there are not a predetermined number of starting cars on the departure floor, a car adjacent to the already designated starting car is designated as the next starting car, so waiting passengers who are scheduled to be left behind are also moved slightly. By simply doing so, you can easily move into the next starting basket.
