Abstract
The present invention relates to a drive element of typewriters or similar office machines where the movement of the platen is derived from the movement of the carriage. In the past numerous drive elements have been required in devices of this type, which required a considerable assembly effort and bearing effort. In contrast hereto the drive element proposed is formed in one piece as a one-armed lever which is rotatably disposed coaxially with the platen and with the line space wheel disposed thereon and which has at least one ratchet which is in operative contact with the line space wheel. A displacement element disposed on the carriage of the machine comes into operative contact with the one-armed lever within a set movement range of the carriage and pivots it, so that the turning of the platen takes place by means of the ratchet.
