ション調整機構。[Claims for Utility Model Registration] 1. In a printer device that unwinds and prints a roll of rolled paper, there is provided a support spring having one end fixed to a part unrelated to the movement of the roll paper and the other end having a friction plate. The spring force is used to press the friction plate against the roll paper, and the spring expands and contracts in response to changes in the diameter of the roll paper. A roll paper back tension adjustment mechanism characterized by increasing or decreasing the dynamic frictional force between the roll paper and the roll paper, and applying a nearly constant back tension to the raw/l/paper unwound during printing. , 2 The spring constant k of the support spring is the minimum winding diameter of the roll paper. , the maximum winding diameter D, the dynamic friction coefficient μ between the friction plate and the roll paper, the roll when the support spring is released, and the rotational friction torque Tf of the part of the paper holder, k=
(4xTf)/(μxD0xD□) A back tension adjustment mechanism for a roll paper according to claim 1, which is a utility model. 3. The back tension adjustment mechanism according to claims 1 and 2 of the utility model registration, characterized in that the remaining amount of roll paper can be displayed by directly displaying the movement of the support spring.
