Description of the Related Art Conventionally, a brake device is provided on the payout side as a mechanism for absorbing slack on the payout side of this type of carbon ribbon, but since the take-up side and the payout side are independent rotation systems, respectively. The ribbon is loosened due to the inertial action of the pay-out roll on the pay-out side against a very small stop due to the intermittent rotation of the step-motor on the take-up side, which is necessary for printing and further for cutting the continuous tag.

ボンに蛇行が発生する。Further, when the ribbon, the tag, or the label is damaged during the printing on the tag, the label, etc., which is transferred and printed by being superposed on the carbon ribbon, the rotation of the print head is released or the platen is separated. When the ribbon, tag, or label is reset, the ribbon has been in contact with the print head for a long time and has run out. Since a certain amount of brake cannot be obtained on the side and printing is performed while the ribbon is slack, the ribbon meanders.

能となる。In the present invention, a part of the belt composed of the coil spring is wound around the outer peripheral portion of the feeding rotation member on the feeding side, and the thermal transfer carbon ribbon is fed from the feeding side and the feeding rotation member is rotated. At this time, the urging force for urging the feeding rotary member in the direction opposite to the feeding direction is accumulated in the coil spring due to the frictional force between the outer peripheral portion of the feeding rotary member and the belt formed of the coil spring accompanying this rotation. Therefore, due to the accumulated force of this coil spring accompanying the rotation of the feeding rotary member,
A constant resistance force can always be applied to the feeding rotary member, that is, the thermal transfer carbon ribbon, and it is possible to guarantee reliable and stable feeding movement of the thermal transfer carbon ribbon.
