By the way, in the embodiment, during the closing operation of the sliding door 1,
If the door closing operation is blocked, an emergency stop means is provided that stops the closing operation of the sliding door 1 and keeps the sliding door 1 fully open. When the motor current increases, it is determined that an abnormality has occurred in the door-closing operation, and the door-closing operation is stopped. That is, in the current detection circuit 12, when the motor current of the drive motor 5 becomes less than a predetermined value,
An abnormality detection signal is output assuming that the door closing operation is blocked and an overload condition has occurred, and upon receiving this abnormality detection signal, the determination control section 13 immediately outputs an opening/closing control signal that reverses the drive motor 5. The sliding door 1 is driven in the opening direction and stopped at the eye-opening position. Therefore, even if a person gets caught between the sliding door 1 and the door frame 111 during the door closing operation, safety can be ensured. In this case, when the sliding door 1, which is stopped in the fully open state, is pulled back in the closing direction by a predetermined distance (for example, about 5c1n), the reed switch 55c is turned on, and the reed switch 55c is reversed (off-on). The door closing operation is restarted, the drive motor 5 is driven in the door closing direction, and the sliding door 1 is electrically closed.

When closing the door, it is necessary to manually lock the door 7M using the lock/unlock switch 23b or the lock/unlock knob 67.

Next, when the automatic/manual changeover switch 22a is set to "manual", the sliding door 1 can be opened and closed manually, and at this time, the opening of the sliding door 1 is set to the closing confirmation switch. When the sliding door 1 is detected, the timer circuit 12 operates, and the manually opened sliding door 1 is automatically closed electrically after a predetermined time set by the timer circuit 12 after the sliding door 1 is opened. However, if the sliding door 1 is opened to the point where it is close to opening (in the embodiment, the opening door detection reed switch 55c operates to close the door), the automatic closing will occur. I try not to hit the door,
The sliding door 1 is kept fully open. This fully open sliding door 1
To close the door, after keeping the sliding door fully open for about 15 seconds, apply a predetermined pressure M (for example, 5 cm IJ) from the opening to the closing direction of the sliding door 1.
