Claims

[Claims for Utility Model Registration] (1) In an ink ribbon device that rotates a drive roller to run an ink ribbon sandwiched between the outer circumferential surface of the drive roller and the outer circumferential surface of a driven roller, the drive roller Or an ink ribbon characterized by being provided with an ink-impregnated roller whose position can be freely changed relative to the driven roller and which is rotationally driven by the outer circumferential surface coming into pressure contact with the outer circumferential surface of any of these rollers. Device. (2) The ink-impregnated roller is rotatably supported by a support member that also serves as a guide, and a separator that is inserted into a groove in the center of the outer peripheral surface of the drive roller or driven roller is fixed to the support member, and
2. The ink ribbon device according to claim 1, wherein the support member is supported on the cassette case so that the position thereof can be changed relative to the driving roller or the driven roller and can be fixed at any relative position. (3) The support member is supported movably along a straight line connecting the rotational axis of the drive roller and the rotational axis of the driven roller, and the outer peripheral surface of the ink-impregnated roller is supported on the straight line by the drive roller. The ink ribbon device according to claim 2, wherein the ink ribbon device is pressed against the outer peripheral surface of the driven roller. (4) Claim (2) characterized in that the support member is interlocked with a cam that can be fixed at any rotation angle.
The ink ribbon device described. (5) The support member according to claim (2) is characterized in that the support member is swingably supported around an axis parallel to the rotational axis of the ink-impregnated roller and can be fixed at any swing angle. Ink ribbon device.
