ABSTRACT:
A winding apparatus for use in a copier, a printer, and other devices for ejecting a printed sheet in a rolled form of a cylinder without having a core includes a gripping mechanism for gripping the leading end of a sheet when the sheet is rolled into cylindrical form. The gripping mechanism is disposed on a cylindrical member provided to each of both ends of the sheet in a direction orthogonal to a conveyance direction of the sheet and moving with the conveyance of the sheet. The on and off states of gripping to the leading end of the sheet can be controlled. The gripping mechanism is turned to the off state, and the cylindrical member is retracted from the sheet.
