しわ発生防止装置。[Claims for Utility Model Registration] (1) A pair of ink ribbon supply reel and take-up reel are provided via a platen, and a head is pressed against the paper wound around the platen via the ink ribbon. In a printer that winds up the ink ribbon while sequentially feeding it and forms images and prints by heating the head, at least one of the ribbon guide rollers disposed on the supply side and the winding side of the ink ribbon sandwiching the platen, The friction coefficient of the circumferential surface of the guide roller on the removal side is set to a predetermined ratio μ2/
An ink ribbon wrinkle prevention device characterized in that a friction coefficient is set to increase with μ1. (2) The ink ribbon wrinkle prevention device according to claim (1), wherein at least both ends of the guide roller on the ribbon winding side are formed so that the surface roughness is rougher than the center part. . (3) The ink ribbon wrinkle prevention device according to claim (1), wherein at least the surfaces of both ends of the guide roller on the ribbon winding side are formed of a material having a larger coefficient of friction with respect to the center portion. . (4) The ink ribbon wrinkle prevention device according to claim (3), wherein a coating layer made of a material having a higher coefficient of friction than the center portion is formed on the surfaces of both end portions of the guide roller. (5) The ink ribbon wrinkle prevention device according to claim (3), wherein members made of a material having a larger coefficient of friction than the center portion are fitted to both ends of the guide roller.
