Claims

[Claims for Utility Model Registration] (1) A paper feed roller on which a pinch roller approaches and separates;
The paper feed roller is provided with an auxiliary roller that is placed in a spaced apart position between the printing section and is in pressure contact with a tension roller, and the auxiliary roller is rotated only in the direction in which the paper is fed from the paper feed roller toward the auxiliary roller. A paper feeding device in a printing mechanism, characterized in that the paper feeding device is connected to a drive system via a one-way clutch mechanism. (2) The auxiliary roller is linked to the rotation of the paper feed roller via a one-way clutch mechanism, has a faster peripheral speed than the feed roller, and has a smaller coefficient of friction than the feed roller. A paper feeding device in the printing mechanism according to scope 1. (31) A paper feeding device in a printing mechanism according to claim 1 or 2 of the utility model registration claim, characterized in that the auxiliary roller and the tension roller are movable in directions away from each other. (4) The auxiliary roller feeds the paper. A paper feeding device in a printing mechanism according to claim 3, characterized in that the paper feeding device is movable around the center of rotation of the roller.
