Mignon 4 typewriter

Manufactured in 1923-1933, the relatively inexpensive Mignon 4 index typewriter was designed to facilitate, and above all automate and accelerate the writing process. One could type on the device by using a pointer suspended above an index, which was a concave board with a table of 84 characters (in a rectangular 7 x 12 layout) attached to the base. The user moved the metal pointer over the selected character using his or her left hand. The position of the drum-shaped type head over a sheet of paper, inserted into the moving carriage of the machine with a rotary rubber platen, changed in accordance with the movement of the pointer over the index board. The index and the head could be easily replaced, which allowed the typeface or alphabet used in the device to be changed (e.g., to Hebrew or Cyrillic). Manufacturer: Europa Schreibmaschinen A.G.
