<P>PROBLEM TO BE SOLVED: To set widely a radial expansion and contraction width, and to surely extract and separate a taken-up sheet roll with simple work. <P>SOLUTION: The other end parts of respective take-up shafts of attaching a radial expansion holding member to a driven side rotor, to be supported, are held in radial expansion positions where axes are brought into parallel one another, when taking up a sheet, the radial expansion holding member is removed from the driven rotor when removing the taken-up sheet roll, to release a support state of the other end part, and the respective take-up shafts are made swingable toward a radial contraction direction along which the other end parts get closer one another, to extract the sheet roll from the respective take-up shafts. <P>COPYRIGHT: (C)2012,JPO&INPIT |
