きくする。Next, the emergency opening / closing operation of the door will be described with reference to the flowchart shown in FIG.・ When the emergency open / close selector switch 15 is closed. When the emergency signal R2 is input from the emergency detector 14 to the control circuit 12, the emergency open / close selector switch 15 is closed in step 100, so that the emergency low speed closing step (non-3) occurs and the control circuit 12 reverses the low speed signal VL. The signal R4 is input to the speed control circuit 8 to drive the motor M in the reverse rotation at a low speed to close the door 5 at a low speed (step 101) and stop at the closed position. When the human body detection signal R1 is input from the human body detector 13 during the operation of closing the door 5 at a low speed for the first time or while holding the door 5 in the closed state, step 102, step 1
In 03, the emergency low speed opening step (non-1) is performed, and the control circuit 12 outputs the low speed signal VL and the forward rotation signal R3 to the speed control circuit 8 to drive the motor M at low speed forward rotation to open the door 5 at low speed. Step 104), and since the emergency open / close selector switch 15 is closed in Step 105, Step 1
When the human body detection signal R1 is input in step 06, the door 5 is continuously opened at a low speed, and the door 5 is opened in step 107.
Position and the low speed open brake point are compared, and when the low speed open brake point is reached, the low speed open brake operation is performed (step 10
8) Then, the door 5 is stopped at the opening stroke end, and it is determined in step 109 whether the door 5 has stopped. If the door 5 has stopped, the emergency open waiting step (non-2) is performed. Door 5 mentioned above
If the human body detection signal R1 is not input during the low speed opening operation of step 106, the process proceeds from step 106 to step 108, and even if the low speed opening brake point is not reached, the low speed opening brake is opened immediately and the door 5 stops and the emergency opening waiting step (non 2). In the emergency wait step (non-2), the emergency open / close selector switch 15 is judged to be opened / closed in the open wait state in step 110, and since it is closed, the routine proceeds to step 111, where the human body detection signal is not input. Sometimes, the process proceeds to step 112, and when the opening waiting time elapses, the process proceeds to the emergency low speed closing step (non-3) described above and the door 5
Closes slowly. When the human body detection signal is input in step 111, the process proceeds to step 113. When the human body detection signal is continuously input for 5 seconds or more, the emergency low speed opening step (non-1) is performed to open the door 5 at a low speed. Then
When the input time of the human body detection signal is 5 seconds or less, the door 5 is kept waiting for opening. In summary of the above operation, when the emergency signal is input, the door 5 is closed at a low speed, the door 5 is stopped at the fully closed position, and when the human body detection signal is input, the door 5 is opened at a low speed. If the human body detection signal is not input, the door 5 is immediately stopped, and if the human body detection signal is continuously input for 5 seconds or longer, the door 5 is opened at low speed. If the human body detection signal is not input within a predetermined time, the door 5 is slowed down. Closes and holds in the fully closed position. In other words, in an emergency, the door 5 is closed at a low speed and held at the closed position, and the door 5 is opened at a low speed in the opening direction in proportion to the input time of the human body detection signal to increase the opening width.

１５が開であるから扉５を開き位置に停止し続ける。When the emergency open / close selector switch 15 is open. When an emergency signal is input, the routine proceeds to the emergency low speed opening step (non-1) in step 100, and when the door 5 is opened at low speed and stopped in the same manner as described above, the emergency open waiting step (non-2) is proceeded to. Since the emergency open / close selector switch 15 is opened at 110, the door 5 is continuously stopped at the open position.
