PURPOSE:To prevent an ink film from generating wrinkles and to prevent a sheet from being caught-in, by providing an ink film stopper having such mechanism as the tip thereof moves according to the variation of the diameter of the ink film near a winding holder thereby discharging static electricity being produced to the body. CONSTITUTION:When printing is carried out, a platen roller 3, a capstan roller 4, an ink film winding holder 8 rotate to rewind a sheet 10 by the amount of single screen. At the same time, an ink film 11 is interlocked with the sheet 10 and wound over the ink film holder 8, so as to loosen the sheet 10 by the amount of single screen between the capstan roller 4 and the paper holder 7. Here, the ink film 11 is prevented from generating wrinkles by means of an ink film stopper 13 when it is wound, while simultaneously static electricity being produced is discharged through the film stopper 13 and a conductive bearing 12 to the body 1. Furthermore, the sheet 10 is prevented from being caught into the ink film winding holder 8 due to loosening of the ink film stopper 13. Consequently, the generation of wrinkles in the ink film and catching-in of the sheet can be prevented.
