<p><P>PROBLEM TO BE SOLVED: To provide an opening/closing device preventing a path of an object sensing medium released from a non-contact sensing part from tilting, moving the non-contact sensing part along a guide rail smoothly. <P>SOLUTION: This opening/closing device for closing an opening/closing body 10 along the guide rail 20 includes the non-contact sensing part 50 supported to protrude in the direction of closing from the opening/closing body 10 and slide in the directions of opening and closing the opening/closing body 10 and sensing an object by the object sensing medium released in the direction of width of the opening/closing body. The non-contact sensing part 50 has a rolling member 53 to rotate freely, an outer peripheral part of the rolling member 53 protrudes onto the bottom side of the guide rail 20, and a face 21 to be rolled for receiving the rolling member 53 and rolling it in the directions of opening and closing of the opening/closing body is provided on the bottom side of the guide rail 20. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
