  • Device for opening and closing opening/closing body
    Patent number: 10675956
    Abstract: When it is determined that there is an individual abnormality, in which an individual drive section is in an abnormal state, while the opening/closing body is being moved by the drive sections or the opening/closing body is stopped in an open state, the opening/closing body operation device performs a restriction control on the drive section with the individual abnormality, the restriction control restricting the movement of the opening/closing body in the closing direction. The opening/closing body operation device makes a comparison of the driving state between the drive section subjected to restriction control and another drive section, and when it is determined that the drive sections are normal with respect to each other, the opening/closing body operation device deems the opening/closing body to be in a normal state and disengages the restriction control.
