Further, as shown in FIGS. 2B and 2C and FIG. 5, a clutch 22 is provided between the driving means 21 and the turning member 23, and the drive force transmission path of the driving means 21 is connected. It is configured so that it can be opened.

また、図５に示すように、制御手段８０には、運転席等に設けられた乗降口開閉スイッチＳｋ、車両３が走行状態であるか否かを検出する走行状態検出手段Ｓｖ、折戸ドア１０が閉ロック状態であるか否かを検出するロック状態検出手段Ｓｓが入力される。なお、走行状態検出手段Ｓｖは、車両３が走行中であるか否かを検出するものであり、本実施の形態では車速センサを用いたが、他のセンサを用いて検出してもよい。
また制御手段８０は、乗降口開閉装置２０のクラッチ２２を接続または開放するクラッチ駆動手段２７と、クラッチ２２が接続されている場合に旋回部材２３を旋回させる駆動手段２１に駆動信号を出力する。
なお本実施の形態にて説明するクラッチ２２は、例えば電磁クラッチであり、クラッチ駆動手段２７にて通電状態にされた場合に動力伝達経路を接続し、非通電状態にされた場合に動力伝達経路を開放する、いわゆるノーマルオープンタイプのものを用いている。 Further, as shown in FIG. 5, the control means 80 includes a doorway opening / closing switch Sk provided at the driver's seat and the like, a traveling state detecting means Sv for detecting whether or not the vehicle 3 is in a traveling state, and the folding door 10. The lock state detection means Ss for detecting whether or not is in the closed lock state is input. The traveling state detection means Sv detects whether or not the vehicle 3 is traveling. In the present embodiment, the vehicle speed sensor is used, but other sensors may be used for detection.
The control means 80 outputs a drive signal to the clutch drive means 27 for connecting or releasing the clutch 22 of the entrance / exit opening / closing device 20 and the drive means 21 for turning the turning member 23 when the clutch 22 is connected.
The clutch 22 described in the present embodiment is, for example, an electromagnetic clutch, which connects a power transmission path when energized by the clutch drive means 27 and connects the power transmission path when deenergized. The so-called normal open type is used.

閉ロック状態（図４（Ａ）の状態）の折戸ドア１０を、駆動手段２１にて動作させる場合、制御手段８０は、クラッチ２２を接続して駆動手段２１を駆動する。すると旋回部材２３に固定された駆動側アームＡ１が旋回し、駆動側アームＡ１に接続されたドア側アームＡ２が前側ドア片１２を開方向に引っ張り、図４（Ｂ）の状態を経由して、図４（Ｃ）に示すように、ステップＳ内にて乗降口５０が全開状態に達する。なお、図４（Ａ）に示す乗降口５０の全閉状態からドア側アームＡ２が折戸ドア１０の引っ張りを開始すると、図２（Ｂ）及び（Ｃ）に示すケーブル２６が引っ張られてロックシャフト６３を下方に引っ張り、ロックピン６２が嵌合部から抜けてロック解除状態となるように構成されている。   When the folding door 10 in the closed lock state (the state shown in FIG. 4A) is operated by the driving means 21, the control means 80 connects the clutch 22 to drive the driving means 21. Then, the drive side arm A1 fixed to the turning member 23 turns, and the door side arm A2 connected to the drive side arm A1 pulls the front door piece 12 in the opening direction, and passes through the state of FIG. As shown in FIG. 4C, the entrance / exit 50 reaches the fully open state in step S. When the door side arm A2 starts pulling the folding door 10 from the fully closed state of the entrance 50 shown in FIG. 4 (A), the cable 26 shown in FIGS. 2 (B) and 2 (C) is pulled and the lock shaft is pulled. By pulling 63 downward, the lock pin 62 is configured to be released from the fitting portion to be unlocked.

●［制御手段の処理手順（図６）］
次に図６に示すフローチャートを用いて、制御手段８０の処理手順について説明する。
例えば制御手段８０は、一定時間毎に図６に示す処理を実行する。
制御手段８０は、ステップＳ１０にて、走行状態検出手段Ｓｖからの検出信号に基づいて車両３が停車中であるか否かを判定する。停車中である（Ｙｅｓ）と判定した場合はステップＳ２０に進み、停車中でない（Ｎｏ（走行中である））と判定した場合はステップＳ５０に進む。
ステップＳ２０に進んだ場合、制御手段８０は、乗降口開閉スイッチＳｋが操作されているか否かを判定する。操作されている（Ｙｅｓ）と判定した場合はステップＳ３０に進み、操作されていない（Ｎｏ）と判定した場合はステップＳ８０に進む。
ステップＳ３０に進んだ場合、制御手段８０は、クラッチ駆動手段２７に駆動信号を出力してクラッチ２２を接続し、ステップＳ４０に進む。
ステップＳ４０では、制御手段８０は、乗降口開閉スイッチＳｋの操作状態に応じて、駆動手段２１を乗降口５０が開く方向または乗降口５０が閉じる方向に駆動し、処理を終了する。 ● [Processing of control means (Fig. 6)]
Next, the processing procedure of the control means 80 will be described using the flowchart shown in FIG.
For example, the control unit 80 executes the process shown in FIG. 6 at regular intervals.
In step S10, the control means 80 determines whether or not the vehicle 3 is stopped based on the detection signal from the traveling state detection means Sv. If it is determined that the vehicle is stopped (Yes), the process proceeds to step S20. If it is determined that the vehicle is not stopped (No (traveling)), the process proceeds to step S50.
When it progresses to step S20, the control means 80 determines whether the entrance / exit opening / closing switch Sk is operated. If it is determined that it is operated (Yes), the process proceeds to step S30, and if it is determined that it is not operated (No), the process proceeds to step S80.
When the process proceeds to step S30, the control unit 80 outputs a drive signal to the clutch drive unit 27 to connect the clutch 22, and the process proceeds to step S40.
In step S40, the control means 80 drives the drive means 21 in the direction in which the entrance / exit 50 is opened or the direction in which the entrance / exit 50 is closed according to the operation state of the entrance / exit opening / closing switch Sk, and the process is terminated.

ステップＳ５０に進んだ場合、制御手段８０は、ロック状態検出手段Ｓｓの検出信号に基づいて折戸ドア１０がロック解除状態であるか否かを判定する。ロック解除状態である（Ｙｅｓ）と判定した場合はステップＳ６０に進み、ロック解除状態でない（Ｎｏ）と判定した場合はステップＳ８０に進む。
ステップＳ６０に進んだ場合、制御手段８０は、クラッチ駆動手段２７に駆動信号を出力してクラッチ２２を接続し、ステップＳ７０に進む。
ステップＳ７０では、制御手段８０は、駆動手段２１に駆動信号を出力することなく停止させて処理を終了する。 When it progresses to step S50, the control means 80 determines whether the folding door 10 is a lock release state based on the detection signal of the lock state detection means Ss. If it is determined that the lock is released (Yes), the process proceeds to step S60. If it is determined that the lock is not released (No), the process proceeds to step S80.
When the process proceeds to step S60, the control unit 80 outputs a drive signal to the clutch drive unit 27 to connect the clutch 22, and the process proceeds to step S70.
In step S70, the control means 80 stops the drive means 21 without outputting a drive signal, and ends the process.

ステップＳ８０に進んだ場合、制御手段８０は、クラッチ駆動手段２７に駆動信号を出力することなくクラッチ２２を開放し、ステップＳ９０に進む。
ステップＳ９０では、制御手段８０は、駆動手段２１に駆動信号を出力することなく停止させて処理を終了する。 When the process proceeds to step S80, the control unit 80 releases the clutch 22 without outputting a drive signal to the clutch drive unit 27, and the process proceeds to step S90.
In step S90, the control means 80 stops the drive means 21 without outputting a drive signal, and ends the process.

以上の処理にて、車両３が停車している場合は、運転席等に設けられた乗降口開閉スイッチＳｋを操作することで、ステップＳ１０−ステップＳ２０−ステップＳ３０−ステップＳ４０の流れにて、折戸ドア１０を動作させて乗降口５０の開閉動作を行うことができる。
また車両３が停車している場合に乗降口開閉スイッチＳｋの操作がない場合は、ステップＳ１０−ステップＳ２０−ステップＳ８０−ステップＳ９０の流れにて、クラッチ２２がＯＦＦ（開放状態）となるので、車内手動ハンドル６０、車外手動ハンドル７０のいずれを操作しても、折戸ドア１０をロック解除状態にして折戸ドア１０を動作させて乗降口５０を開くことができる。
また、車両３が走行中に、誤って車内手動ハンドル６０が操作されて折戸ドア１０が閉ロック状態からロック解除状態になった場合であっても、ステップＳ１０−ステップＳ５０−ステップＳ６０−ステップＳ７０の流れにて、クラッチ２２をＯＮ（接続状態）且つ駆動手段２１を停止状態として、折戸ドア１０を動作させようとした場合に駆動手段２１を制動装置として利用するので、乗降口５０が開くことを禁止することができる。
なお、ブザーやインジケータ等の報知手段を備え、走行中にロック解除状態を検出した場合、制御手段８０を用いて報知手段から警報を出力させるようにしてもよい。 In the above processing, when the vehicle 3 is stopped, by operating the entrance / exit opening / closing switch Sk provided in the driver's seat or the like, in the flow of Step S10-Step S20-Step S30-Step S40, The folding door 10 can be operated to open and close the entrance 50.
Further, when the vehicle 3 is stopped and there is no operation of the entrance / exit opening / closing switch Sk, the clutch 22 is turned off (disengaged) in the flow of step S10-step S20-step S80-step S90. Regardless of which one of the in-vehicle manual handle 60 and the out-of-vehicle manual handle 70 is operated, the door 50 can be opened by moving the folding door 10 with the folding door 10 unlocked.
Further, even when the in-vehicle manual handle 60 is erroneously operated while the vehicle 3 is traveling and the folding door 10 is changed from the closed locked state to the unlocked state, Step S10—Step S50—Step S60—Step S70. In this flow, when the clutch 22 is turned on (connected state) and the driving means 21 is stopped and the folding door 10 is to be operated, the driving means 21 is used as a braking device, so the entrance 50 is opened. Can be prohibited.
Note that a notification unit such as a buzzer or an indicator may be provided, and when the unlocked state is detected during traveling, the control unit 80 may be used to output an alarm from the notification unit.
