摘要

In an electrically controlled typewriter, a printer or the like it is provided that for the read-out of a magnetic coding on a rotationally driven part a sensor emits output signals in reference to a changing magnetic field. Preferably the sensor is in the form of a pulse wire. A ribbon cassette for such a typewriter is distinguished by the disposition of at least one magnet on a rotationally driven part Advantageously this is a Wiegand wire. A type wheel can be coded in a corresponding manner.
