Abstract:
An automatic opening/closing apparatus, comprising:a moving member for performing an opening/closing movement by receiving a driving force from a driving means;position detecting means for detecting the position of the moving member;load detecting means for detecting a load on the driving means if the movement of the moving member is restricted when the driving means is in a driving state;a pressure sensitive sensor located on the moving member for moving integrally with the moving member, and for detecting pressure applied to an end portion in the moving direction of the moving member;determining means for determining whether or not a state in which a load of a reference value or greater is detected by the load detecting means is an overloaded state and whether or not a state in which pressure of a reference value or greater is detected by the pressure sensitive sensor is a pressed state;controlling means for controlling the driving of the driving means if it is determined by the determining means that the state is at least one of the overloaded state and the pressed state; andreference-value changing means for changing at least either one of a reference value for determination of the overloaded state by the determining means and a reference value for determination of the pressed state by the determining means, in correspondence with a position of the moving member detected by the position detecting means;wherein the load detecting means does not detect the load on the driving means in correspondence with the position of the moving member detected by the position detecting means.
