Abstract
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.
