摘要： A cartridge for a typing ribbon and spools for a correcting ribbon are mounted on a common frame which can tilt about a spindle. In a lowered position of the frame the typing line behind a daisy wheel is visible. The frame is raised by a first stroke to the position shown to dispose the typing ribbon over the typing point on the platen. A longer stroke raises the correcting ribbon to the typing point and this longer stroke also actuates an automatic ratchet wheel and pawl type of feed mechanism for the correcting ribbon. The two strokes of the frame are controlled by a disc comprising two cam tracks with a common part and separate parts having different degrees of eccentricity relative to the common part. The grooved cam tracks are so shaped that a follower pin on an arm depending from the frame enters the radially inner track when the disc is rotated clockwise by a reversible electric motor, thereby to raise the frame by the smaller amount, whereas it enters the radially outer track in the case of anticlockwise rotation. The disc also carries a frontal cam which operates a ribbon feed mechanism for the ribbon in a container of the cartridge.

摘要翻译： 用于打字色带的盒和用于校正色带的卷轴安装在可绕主轴倾斜的公共框架上。 在框架的下降位置，菊花轮后面的打字线是可见的。 框架通过第一笔划升至所示位置，以将打字色带配置在稿台上的打字点上。 更长的行程将校正色带提高到打字点，并且这种较长的行程还启动用于校正色带的自动棘轮和棘爪类型的进给机构。 框架的两个笔画由包括具有公共部分的两个凸轮轨道和相对于公共部分具有不同偏心度的分离部分的盘来控制。 带凹槽的凸轮轨道的形状使得当盘由可逆电动机顺时针旋转时，从框架悬垂的臂上的从动销进入径向内部轨道，从而将框架升高较小的量，而其进入径向 在逆时针旋转的情况下的外轨道。 盘还带有正面凸轮，其操作用于色带在色带盒的容器中的色带供给机构。

摘要： A print head (15) on a carriage (16) slides on a carriage guide bar (17) in front of a platen bar (18). A receipt slip (25) is fed from a roll (26) over part of the width of the platen bar (18) to a knife (40) for cutting off individual receipts. A daybook slip (45) is fed from a roll (46) over the bar (18) to a take-up roll (50). Other documents may be fed in for printing either downwardly between upper guides (37 and 38) or upwardly between lower guides (35 and 55). In either event the inserted document is engaged by a drive roller (60) and pressure roller (70) to be positioned at a predetermined height, under control of photodetectors (80 and 81). The pressure roller (70) is mounted between levers and can move away from the drive roller (60) to accommodate the thickness of the inserted document. The levers also support the carriage guide (17), whereby the head (15) is positioned a constant distance from the surface on which printing is effected.

摘要： A line spacing device for printing machines comprises an electric motor arranged to rotate selectively in a clockwise direction and anticlockwise direction and a control disc carrying a pawl on an eccentric. The tooth of the pawl describes a closed trajectory engaging in the teeth of a wheel and of a sense the same as the rotation of the disc, whereby a paper support platen is rotated by one increment in the opposite sense. A central control unit controls the clockwise and anticlockwise rotations of the electric motor. A cam disengages a detent pin from the wheel so that the motor is only lightly loaded when actuating the platen.

摘要翻译： 用于印刷机的线间隔装置包括：电动机，其布置成沿顺时针方向和逆时针方向选择性地旋转;以及控制盘，其在偏心轮上承载棘爪。 棘爪的齿描述了一个闭合的轨迹，其啮合在车轮的齿上并且具有与盘的旋转相同的感觉，由此纸张支撑压板以相反的方向旋转一个增量。 中央控制单元控制电动机的顺时针和逆时针旋转。 凸轮使止动销从轮子上脱开，使得当致动压板时电动机仅被轻轻地加载。
