    • A paper cutting device for cutting sheet material from the lengthwise edges of the material toward the middle comprising a stationary blade and first and second movable blades with the sheet material placed between the stationary blade and the first and second movable blades. The paper cutting device enables the spacing between the stationary blade and the first and second movable blades to be opened by moving the stationary blade frame and the movable blade frame relative to each other. The first movable blade and second movable blade are supported on a first stud and second stud, respectively, near the distal ends of the edge of the blade part of the stationary blade so that the paths of the blade tips overlap when cutting the sheet material. The movable blade drive mechanism drives the first movable blade and second movable blade with the first movable blade leading and the second movable blade following.
    • 一种用于从材料的纵向边缘向中间切割片材的切纸装置,包括固定刀片和第一和第二可动刀片,其中片材被放置在固定刀片与第一和第二可动刀片之间。 切纸装置通过相对于彼此移动固定刀片框架和可动刀片框架,能够使固定刀片与第一和第二可动刀片之间的间隔打开。 第一可动刀片和第二可动刀片分别支撑在固定刀片的刀片部分的边缘的远端附近的第一螺柱和第二螺柱上,使得当切割片材时刀片尖端的路径重叠。 可移动刀片驱动机构利用第一可动刀片引导件和第二可动刀片跟随来驱动第一可动刀片和第二可动刀片。

    • A printer having a paper discharge mechanism which reliably prevents recording paper after completion of the printing operation from being pulled back inside the printer. The printer includes a paper feed roller 62 located on the upstream side of the printing position 83 along the horizontal paper transportation path of the printer. A paper cutting mechanism 67 is located downstream from the printing position. A pressure roller 66 presses the recording paper against a discharge roller 65 from the top side of the paper transportation path. A reversing-prevention lever 80 is disposed coaxially and freely rotatably to the pressure roller 66. The center of gravity of the reversing-prevention lever 80 is downstream from the axis of rotation 66e of the pressure roller 66, and the weight of the reversing-prevention lever 80 causes the reversing-prevention lever 80 to contact the top of the discharged paper 10. If the trailing end of the cut and discharged paper 100, which rests on top of the leading end of the roll paper 10, moves with the leading end of the roll paper 10 when the roll paper 10 is pulled back inside the printer after cutting, the trailing end of the discharged paper 100 contacts the reversing-prevention lever 80 and is thus prevented from being pulled back inside the printer.
    • 具有排纸机构的打印机,其可靠地防止在完成打印操作之后的记录纸被拉回打印机内部。 打印机包括位于打印位置83的沿着打印机的水平纸输送路径的上游侧的供纸辊62。 切纸机构67位于打印位置的下游。 压力辊66从纸张输送路径的上侧将记录纸压靠在排出辊65上。 反转防止杆80同轴且可自由转动地设置在加压辊66上。 反转防止杆80的重心位于加压辊66的旋转轴线66e的下游,防倒转杆80的重量使反转防止杆80接触排出的顶部 纸10。 如果在切割后将卷纸10在打印机内拉回卷筒纸10的前端时,搁置在卷纸10的前端顶部的切出排出纸100的后端移动, 排出纸100的尾端与防倒转杆80接触,从而防止在打印机内被拉回。
