Ribbon snaking prevention device null of transcription die heat sensitive

摘要

PURPOSE:To make it possible to prevent the meandering of a ribbon and the generation of wrinkles due to differences in tensile force in the lateral direction, by cutting the ribbon after the completion of printing in the lateral direction to indivisually and independently separate differences in tensile force thereof. CONSTITUTION:A cutter 37 is fixed to the forward upper part of a support frame 28A and the blade surface 37a thereof is slightly protruded from a frame 26 to cross the passage of a ribbon 1 to be held to a state capable of cutting the ribbon 1. Further, a cutter 41 having a blade surface 41a provided inside thereof is provided. A predetermined number of blade cutters 37, 41 are provided in the lateral direction of the ribbon 1. The ribbon 1 after the completion of printing crosses the cutters 37 at a position where it has passed a printing part P and rapidly divided into five sections in the lateral direction thereof by the cutters 37. Even if the tensile force of the ribbon is different in the lateral direction, the ribbon is divided so that tensile forces of the divided ones exert no effect on each other and, as a result, the ribbon can be prevented from being wrinkled.
