    • Several line drawing devices to permit drawing horizontal and vertical lines on typewriters are known. The fact that they are rarely encountered in practice, should be sufficient proof that they were not found to be satisfactory and greatly impede the typing process. These drawbacks are overcome by the invention in that the ribbon cassette is provided with a receptacle for a colored writing implement which, in one end position, resiliently rests on the record carrier so as to produce drawn lines and is arranged to be movable and arrestable in another end position to put it out of operation. A significant advantage resides in the fact that the colored writing implement can here be attached to the cassette at a location where the typing process is not interfered with. The colored writing implement can easily be exchanged by removing the ribbon cassette. The ribbon cassette together with the colored writing implement permits easy production of drawn lines in the horizontal, vertical or any other direction. Exchange of the colored writing implement can be effected without any particular skill on the part of the operator.
    • 众所周知,可以在打字机上绘制水平和垂直线的几条线条画设备。 在实践中很少遇到的事实应该足以证明它们没有被认为是令人满意的,并且极大地阻碍了打字过程。 本发明克服了这些缺陷,因为色带盒设置有用于彩色书写工具的容器,其在一端位置弹性地放置在记录载体上,以便产生绘制的线,并且被布置成可移动和阻止在 另一个最终的位置使其失去作用。 显着的优点在于,彩色书写工具在这里可以在打字过程不受干扰的位置附接到盒子。 彩色书写工具可以通过取下色带盒轻松更换。 色带盒与彩色书写工具一起允许在水平,垂直或任何其他方向上容易地生产绘制的线条。 彩色书写工具的交换可以在操作者没有任何特定技能的情况下进行。
