Abstract

Abstract PURPOSE:To eliminate trouble due to over-taking-up, by providing a boundary mark at an appropriate position of the entire length of an ink ribbon and reducing a take-up amount by the detection signal of said mark. CONSTITUTION:An adjusting means 28 is constituted so as to reduce the number of pulses of a pulse generator 27 controlling a drive means 25 when a detector 24 detects a boundary mark 20 placed on the two-split position of an ink ribbon 14, that is, when the winding diameter of an original winding core 15 is almost equal to that of a take-up core 16. The reduction ratio of the number of pulses is adjusted so that the take-up amount in the middle of the entire length of the ink ribbon 14 is almost the same as the take-up amount at the initial stage of taking-up. By this method, the generation of trouble in which almost all part of the head sides of monochromatic parts Y, M, C become wasteful with over-taking-up or discrimination marks 1 to 3 are not detected by the detector 24 during the printing of the monochromatic parts Y, M, C or the discrimination marks 1 to 3 themselves are printed, is eliminated and a printing time can be shortened and printing quantity can be enhanced without increasing the winding diameter of the scroll in the original winding side.
