ABSTRACT:
In an automatically opened and closed mechanism, such a power window, a sunroof or the like, which is opened and closed automatically, a contact sensitive control apparatus according to the invention includes a sealed tube stretched on a frame of an opened and closed portion. A change in the pressure within the tube produced by contact with the frame when the opened and closed portion is closed is sensed by a pressure sensor. When the change in the pressure is detected, the closing of the opened and closed portion is stopped at once. This allows the occurrence of an accident of injury to be prevented in advance which includes portion of a human body being pinned by the window or the like when the opened and closed portion is closed.
