Abstract

PURPOSE:To prevent the smearing of a recording paper with an ink or folding of an ink ribbon from occurring, by releasing the pressing of a printing head against a platen in the condition where take-up of the ink ribbon is stopped, and again driving the ink ribbon after the head is separated from the recording paper. CONSTITUTION:When the final dot in a printing line is printed, take-up of an ink ribbon 10 is stopped in the condition where a carriage 1 is continuedly moved. The pressing of a printing head is released in this condition, so that a take-up tension is not exerted on the ink ribbon 10 at the moment the head 3 is separated from a recording paper 11. Therefore, no slip occurs between the paper 11 and the ribbon 10, and contamination of the paper 11 does not occur. With the head 3 separated from the paper 11, the ribbon 10 is again taken up for a predeterimed period of time, so that a slack in the ribbon 10 is straightened, and the ribbon 10 is prevented from being folded at the start of printing of the next line.

Effects of the Invention In the thermal transfer printer of the present invention, an ink ribbon winding drive means is provided in addition to the print head movement drive means, and the ink ribbon winding is performed after printing interruption of each printing line or after printing is completed. After the take-up is stopped, the print head is no longer pressed against the platen, and after the print head is separated from the recording paper, the ink ribbon is again taken up for a sufficient time to take up the slack in the ink ribbon. In other words,
After the print head leaves the recording paper, the slack in the ink ribbon is taken up by re-driving the ink ribbon, so when the print head is pressed against the platen when printing the next line, the ink ribbon may break. This eliminates inconveniences such as the occurrence of.

Also, when the ink ribbon winding is stopped,
Since the print head is no longer pressed against the platen, winding tension does not act on the ink ribbon at the moment the print head leaves the recording paper. Therefore, since no slipping occurs between the recording paper and the ink ribbon, ink stains do not occur on the recording paper.
