PROBLEM TO BE SOLVED: To make connection to a connector at a sheet side smoothly, and to prevent foreign matters from entering a connector at a floor side when the connector has not been connected yet. SOLUTION: The connector 77 at the floor side is rotatably supported by an arm 78 at one shaft 83, the arm is supported rotatably at the floor side by the other shaft 79, and the connector at the floor side becomes horizontal when it is connected and not connected to a connector 8 at a sheet side. A storage 82 for storing the connector 77 is provided at the floor side on the floor 2, so that the connector at the floor side becomes horizontal when it is stored at the floor side. The other shaft 79 is rotatably supported by a slide base 80, so that the slide base can slide freely along the floor with the sheet 1. A guide rail 81 for slidably engaging the slide base 80 is provided, and a storage 82 is provided while it communicates with the guide rail. COPYRIGHT: (C)2007,JPO&INPIT
