摘要： A flap-armature electromagnet comprises a U-shaped yoke, a pole core, a coil, a flap-armature, a compression spring and a coil spring. The flap-armature is rockingly supported on the yoke by means of projections formed at the upper rear end of the yoke and notches formed at both sides of the flap-armature. Each end of the coil spring is connected to each of the projections for pressing the flap-armature on a rocking axis of the flap-armature.

摘要： A ribbon cartridge includes a pair of housings having apertures, a pair of ribbon spools rotatably supported in the housings, and a ribbon wound on the spools. A portion of the ribbon is exposed to the outside of the housings through the apertures when the ribbon is fed from one spool to the other. Each housing rotatably supporting a hold member. The hold member has a holding portion which is movable across a ribbon passage within the respective housings for holding the ribbon and has an engaging portion which is engageable with teeth on a flange of each spool, and each hold member is biased by a spring member. When the cartridge is removed from the typewriter, the holding portion is moved across the ribbon passage and a portion of the ribbon slackened and exposed from the housing is tensioned. The engaging portion prevents the rotation of the respective spools by the biasing force of the spring member, and when the cartridge is installed in the typewriter, the hold member is retracted to a released position by a retract member of the typewriter.

摘要： 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.

摘要： A wire printer printing head comprises a support member, a plurality of printing elements having a print wire with a flap-armature electromagnet and a sound absorbing cover. The printing element are radially and slidably mounted to the support member and adjustable to a mounting position of each printing element with respect to the support member by an eccentric pin. The sound absorbing cover composed of a core plate and sound absorbing material is secured to the support member and surrounds all printing elements.
