The case of the manual fixing full-open mode will be described (FIG. 7). In a standard one stroke, the mat switch 9 is turned on, the door 1 is moved from the fully closed state to the fully opened state, is fully opened for a certain period of time, and then is closed to be fully closed. When the mat switch 9 is turned on during the closing stroke, the mating switch 9 is reversed to the opening stroke to be fully opened, and after being fully opened again for a certain period of time, it is closed to be fully closed.

When the fully opened door is closed by 5 cm or more by an external force, it is opened again to be fully opened.

The case of the half-open mode of manual fixing will be described (FIG. 8). In one standard stroke, the mat switch 9 is turned on, the door 1 moves from fully closed to open to half open, and after half open for a certain period of time, it closes to full close. When the mat switch 9 is turned on during the closing stroke, the mating switch 9 is reversed to the opening stroke and is half-opened, and after half-opening is continued for a certain period of time, it is closed and fully closed.

When the start signal from the mat switch 9 is continuously input for more than 5 seconds after the half-opening is continued for a certain period of time in the half-opening stroke, the opening is moved to the full-opening. If the door 1 is further opened by an external force of 5 cm or more during the half-opening stroke, the door 1 is opened to be fully opened. If the door 1 is further closed by an external force of 5 cm or more during the half-opening stroke, it opens and returns to half-opening.

The case of the automatic half-open variable mode will be described (FIG. 9), but the predetermined number of times of reversal N is 3 and the door opening increase (L) is 20 cm. In the standard one stroke, the mat switch 9 is turned on, the door 1 is opened from the fully closed state to the initial half open state (b in FIG. 3), and the door is closed for a certain period of time and then closed to be fully closed. When the mat switch 9 is turned on during the closing stroke, the mating switch 9 is reversed to the opening stroke and is half-opened, and after half-opening is continued for a certain period of time, it is closed and fully closed.

When the number of reversals reaches three times in succession, the initial half-opening degree (b in FIG. 3) plus 20 cm is set as a half-way opening degree (c in FIG. 3), and the half-opening degree is half-opened. After half-opening for a certain period of time, it closes and fully closes.
