<P>PROBLEM TO BE SOLVED: To provide a connection-type pressure-sensitive sensor that is matched to the folded angle of the corner part of a frame body, even if bending inclination or the like is not given, can be easily continuously laid in a desired length and can eliminate detection leakage of sandwiching, and to provide an opening and closing device. <P>SOLUTION: A pressure-sensitive sensor 17 makes the desired length by connecting a plurality of the connection type pressure sensitive-sensors 18a, 18b, 18b and 18c provided with plugs 8 or jacks 9 connecting the other connection type pressure-sensitive sensors and couplers, at the end. The pressure-sensitive sensor 7 can be laid on the corner part, without giving bending tendency to a piezoelectric element material 33 itself, constituting the pressure sensor 17, by giving a curved shape corresponding to the corner part of an opening part or an opening member laying the pressure-sensitive sensor 17 to the plug 8 or the jack 9 which constitute the couplers. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
