ていることを特徴とするインクリボン走行構造。 In the ink ribbon running structure, a reversal prevention mechanism 9 is provided on the roller 4 on which the ink ribbon R is held, and the running direction of the ink ribbon R is restricted to one direction by preventing the roller 4 from reversing. A reversal prevention mechanism 9 includes a coil spring 9b installed concentrically with the rotation axis X of the roller 4 or a rotating member that rotates in conjunction with the rotation of the roller 4, and a coil spring 9b installed concentrically with the rotation axis X of the roller 4 or a rotating member that rotates in conjunction with the rotation of the roller 4. Both ends are connected to the roller 4 or the rotating member and the stationary member 2.
and regulating surfaces 9d and 10a that regulate the elastic deformation of the coil spring 9b engaged by the engagement mechanism 9c in the coil radial direction due to the reverse rotation of the roller 4. An ink ribbon running structure comprising:
