    • A paper registration apparatus for a duplex printer which performs side registration of a sheet of paper before the paper is transferred toward a feed roller to print an image on a rear side of the paper after a front side of the paper is printed. The apparatus includes a lower guide plate supporting the paper thereon and having a groove formed at one side, a side wall guide vertically installed at the side of the groove of the lower guide plate parallel to a direction of a paper transfer route to perform a side registration of the sheet of paper, and a duplex transfer roller installed perpendicular to the direction of the paper transfer route. The apparatus further includes an idle roller installed above the duplex transfer roller at a predetermined inclination angle with respect to the duplex transfer roller, an idle roller rotation shaft holder rotatably supporting both ends of a rotation shaft of the idle roller, a pressing unit providing an elastic force to the idle roller toward the duplex transfer roller, and a pivot unit setting the inclination angle of the idle roller within a predetermined range according to a type of paper.
    • 一种用于双面打印机的纸张对齐装置,其在打印纸张的正面之后将纸张朝向馈送辊传送以在纸张的背面上打印图像之前执行纸张的侧面对齐。 该装置包括:一个支承纸张的下导向板,在其一侧形成一个凹槽;一个侧壁导向件,垂直地安装在下导向板的凹槽侧,与导纸板的一个方向平行, 记录纸张,以及垂直于纸张传送路线安装的双面转印辊。 所述设备还包括:空转辊,所述空转辊相对于所述双面转印辊以预定倾斜角度安装在所述双面转印辊上方;惰辊转动轴保持器,其可转动地支撑所述惰辊的转动轴的两端;加压单元, 对空转辊施加朝向双面转印辊的弹力,以及根据纸张类型将空转辊的倾斜角度设定在预定范围内的枢轴单元。

    • PURPOSE: A paper alignment apparatus of a duplex printer is provided to efficiently align sides of paper by variably setting inclination of a movement roller according to types of paper when printing another surface of the paper in the duplex printer. CONSTITUTION: A paper alignment apparatus of a duplex printer includes a lower guide plate(182), a side wall guide, a duplex conveyance roller(190), an idle roller(191), a rotation shaft holder, and a rotation unit. The lower guide plate(182) supports printer paper and has a predetermined groove. The side wall guide is installed in parallel to a paper conveyance route. The duplex conveyance roller(190) is installed in a vertical direction to the paper conveyance path. The idle roller is installed in an upper part of the duplex conveyance roller. The rotation includes an elastic unit which elastically supports one side of the rotation shaft holder.
    • 目的:提供双面打印机的纸张对准装置,以便在双面打印机中打印纸张的另一个表面时,根据纸张的类型可变地设置移动辊的倾斜度来有效地对准纸张的侧面。 构成:双面打印机的纸对准装置包括下引导板(182),侧壁引导件,双面传送辊(190),空转辊(191),旋转轴保持器和旋转单元。 下引导板(182)支撑打印纸并具有预定的凹槽。 侧壁引导件平行于纸张输送路径安装。 双面传送辊190沿纸张输送路径的上下方向安装。 空转辊安装在双面输送辊的上部。 旋转包括弹性地支撑旋转轴保持器的一侧的弹性单元。
