Abstract
A ribbon cartridge for typewriters having a plurality of type bars which have the respective type fonts or characters at the top portions thereof and which are struck toward a printing point on a platen during the printing operation. The ribbon cartridge includes a pair of housings made of plastic material and a connecting arm member made of a metal strip for interconnecting the two housings. The connecting arm member has its center portion positioned in front of a type bar guide (on the side of the typist) and is formed substantially into a U-shaped opening as seen from the front side of the typewriter in order to permit the printing operation of the respective type bars. A spool for winding the printing ribbon is rotatably mounted in each housing, the spool being operatively connected in the usual manner to an ordinary ribbon drive means which is provided on the typewriter. Each one of the housings is provided with an aperture or slot to allow passage therethrough of the printing ribbon. A printing ribbon which is wound on one spool is fed through the aperture in its housing and taken up on the other spool through the aperture in the other housing.
