    • A paper pickup unit and an image forming apparatus having the same are provided to prevent the rear end of a paper from being twisted when the paper is passing through a transfer unit by rotating idle rollers which are installed at two sides of a pickup roller at the same speed. A paper pickup unit comprises a pickup roller having a circumferential section and a non-circumferential section. Idle rollers(120) are installed at two sides of the pickup roller. A connection unit connects the idle rollers with each other so that the idle rollers rotate together. The connection unit includes an idle pin(131a) which passes through the pickup roller. Planet gears(131) are installed at two sides of the idle pin. A sun gear, installed at the idle roller, meshes with the planet gears. The planet gear rotates on its axis while revolving around the sun gear when the paper is picked up at the circumferential section.

    • PURPOSE: A method for aligning papers in duplex printer is provided to easily align front ends of papers by controlling a rotation of a feeding roller when papers are misaligned. CONSTITUTION: A paper is fed towards a feeding roller(30) by means of a duplex feeding roller(90). At this time, rotation of the feeding roller(30) and an anti-dual feeding roller(35) is stopped before a front end of the paper reaches a contact line between the anti-dual feeding roller(35) and the feeding roller(30). Thus, contact line formed between the anti-dual feeding roller(35) and the feeding roller(30) blocks the front end of the paper so that the front end of the paper is aligned in parallel to a rotating shaft of the feeding roller(30). Then, the anti-dual feeding roller(35) and the feeding roller(30) are rotated so as to continuously feed the paper.
    • 目的:提供一种在双面打印机中对齐纸张的方法,以便在纸张未对齐时通过控制进纸辊的旋转而容易地对齐纸张的前端。 组成:纸张通过一个双面进纸辊(90)送入进纸辊(30)。 此时,在纸张的前端到达防双重馈送辊(35)和馈送辊(35)之间的接触线之前停止馈送辊(30)和防双重馈送辊(35) 30)。 因此,在防双重进给辊(35)和进给辊(30)之间形成的接触线阻挡了纸的前端,使得纸的前端与进给辊的旋转轴平行 30)。 然后,防双重馈送辊(35)和馈送辊(30)旋转以连续馈送纸张。
