Abstract

PURPOSE:To enhance printing quality by preventing the generation of the wrinkles of an ink film, by pressing the end part of a ribbon feed by the conical tapered part provided to at least one of a ribbon feed gear and a ribbon feed presser. CONSTITUTION:A ribbon feed 25 is held by a ribbon feed gear 26 and a ribbon feed presser 28 equipped with a truncated cone shape. Therefore, even when thermal expansion are generated in the ribbon feed 25, backlash is not generated since it is absorbed by the tapered part of the ribbon feed presser 28 equipped with the tapered part. Even when the ribbon fed 25 is not positioned on the same axis as the ribbon feed gear 26 and ribbon feed presser 28 equipped with the taper part, the end part on the side of the ribbon feed presser is positioned at the most stable part on the tapered part during the feed of an ink film and, therefore, the ribbon feed 25 is positioned on the same axis. As a result, the generation of the wrinkles of the ink film can be prevented.
