摘要： Printing apparatus with a roller platen and a plastic strip for holding paper against the roller platen even if insufficient paper is fed through to reach the usual guide rollers. The plastic strip is arranged in a closed loop and is connected to the print element to move with it in the line direction. The strip has a perforation for the penetration of printing type or the like.

摘要： An electromagnetic drive mechanism for a pin in a matrix printing head has a first magnet with an articulated armature, wherein a free end of the armature acts on the pin and can be returned to a disengaaged position by a recovery mechanism. The recovery mechanism comprises another articulated-armature magnet with an armature identical with that of the first magnet but with a yoke mounted on a side of the armature that faces away from a yoke of the first magnet.

摘要： Printing or recording apparatus for the selective printing of single sheets or margin-perforated endless paper in which for the endless paper operation a separate conveying unit can be put in place on the printer housing which unit is provided with conveying means engaging in the perforated margin of the endless paper. The sight case of the conveying unit is arranged over the feed opening as well as the delivery unit for the single sheets. A movable lid permits access to these openings for the single-sheet operation but covers these completely and in a soundproofing way for endless paper operation. Connected with the movable lid there is a prop which in the closed position of the lid automatically lifts off the platen the feed rolls not required in this operating state.
