Abstract:
An automatic opening-and-closing device comprising:a moving body which moves for opening/closing substantially horizontally by means of a driving force from a driving means; a pressure sensitive sensor which is provided along a vertical direction of the moving body at a moving direction side end portion of the moving body, comprising a plurality of electrodes which are respectively elongated along the vertical direction and which are disposed with gaps therebetween, the pressure sensitive sensor detecting an external pressure due to the plurality of electrodes bending and contacting each other; an elongated connection means, one end of which is electrically connected to ones of longitudinal direction end portions of the plurality of electrodes said connection means having a part which turns and then extends along the vertical direction; support means having a holding portion for holding the pressure sensitive sensor along the longitudinal direction of the plurality of electrodes, and having a support portion which is mounted to and supported at a predetermined sensor mounting position, wherein the support portion has an accommodating portion which accommodates a portion of the connection means and guides the portion of the connection means to other longitudinal direction end sides of the plurality of electrodes; and control means for controlling driving of the driving means, said control means being connected to the pressure sensitive sensor via the connection means and controlling driving of the driving means when the pressure sensitive sensor senses an external pressure.
