Claims

[Scope of Claim for Utility Model Registration] 1 Loading means that presses the paper surface with a biasing member, printing means that reciprocates in a direction perpendicular to the paper feeding direction with respect to the paper surface, parallel to the paper surface and in the feeding direction The feeding means rotating integrally with a drive shaft perpendicular to In a paper feeding mechanism of a printer that removes slack over a surface and prints with a printing means, there is provided a friction roller mechanism having a friction roller that presses the paper surface against the roller with a load means and rotates in a counter-feeding direction, and the friction roller. between the mechanism and the feeding means,
When the drive shaft of the feeding means is rotated in the feeding direction, the feeding means is rotated in the feeding direction, and when the drive shaft is rotated in the anti-feeding direction, the friction roller is rotated in synchronization with the feeding means in the anti-feeding direction. A paper feeding mechanism for a printer, characterized in that a paper feeding mechanism for a printer is provided. 2. The printer according to claim 1, wherein the friction roller mechanism comprises a drive source, a friction roller parallel to the drive shaft of the feeding means and pivotally supported at both ends, and a power transmission member that transmits the driving force of the drive source to the friction roller. paper feeding mechanism. 3. The paper set adjustment mechanism includes a driving link provided at the end of the drive shaft of the feeding means via a one-way clutch,
3. A paper feeding mechanism for a printer according to claim 2, wherein a driven joint is provided at an end of the friction roller shaft of the friction roller mechanism, and a connecting joint is provided between the driving joint and the driven joint. 4. The paper set adjustment mechanism is provided with a driving link via a one-way clutch at the end of the drive shaft of the feeding means,
3. A paper feeding mechanism for a printer according to claim 2, wherein a driven node is provided in the drive source of the friction roller mechanism, and a connecting node is provided between the driving node and the driven node.
