摘要： A matrix pin print head of the hinged clapper armature construction includes several pin systems which, in each case, include a magnetic yoke limb pair (2), an electromagnetic coil (3), a hinged clapper armature (4), and a print pin (1). The multiple pin system further includes an electromagnetic coil support (13), which is produced by way of sintering or precision-casting, and which forms a single-piece component together with a base plate and the magnet yoke limb pairs (2). In a system with a low number of pins such as nine pins, the electromagnetic coil support (13) exhibits radially outwardly individual magnet yoke limbs (2a) and an armature guide, wherein the individual hinged clapper armatures (4) are precisely positioned and without cause for a loss of magnetic energy. In each case, the magnetic yoke limbs are directed toward a pin engagement point (8) or, respectively, to a pin attachment position (8b). The radial inner magnet yokes are formed to a closed, circular, or polygonal ring (17). Guide means (18), coordinated in each case to a course of pivot motions of the hinged clapper armatures (4), are coordinated to the hinged clapper armatures (4), where the guide means (18) cooperate with the receiving means (19) at the closed ring (17).

摘要： In a sheet feeding apparatus for separating individual sheets (1b, 1c) of different stiffness from stacks (1d) thereof, the stack is pressed under the urgency of a spring force against separating rollers (9) and the sheet supply container (1) has an inclined front wall surface (10) on its front wall (4) upon which the stacked sheets are supported. A pair of arms (12) carrying separating elements (3) on their lower ends are carried on the supply container side wall (1a) for substantially parallel movement therealong. The arms (12) are implemented as linearly-movable switch sides (13) which are reciprocally displaceable between a lowered position in which the separating element end surfaces (15) rest against the supply container front wall surface (10) or the front region (11) thereof, and an upper or raised position in spaced apart relation to and providing a well-defined clearance (16) relative to the topmost sheet in the stack (1d).

摘要： A paper transport device in printers (1), particularly in dot matrix printers, for the feeding of continuous webs (6) by transversely displaceable tractors (7, 8) which are arranged in pairs on the printer frame. The tractor pins (9) engage into the edge perforations of the continuous web (6) and the pin belts (10) are guided over at least one wheel (11) of the tractor (7, 8) and at least one driven tractor wheel (13) is present. The device is equipped with a locking device so that the tractor (7, 8) operating as push means or as pull means is mounted in each case on a drive shaft (14) and in each case prevented from turning on the printer fram (1a) by a projection (16) on the side (15a) opposite the drive shaft (14) or by a swingable tractor flap (24).
摘要翻译：一种打印机（1）中的纸张传送装置，特别是点阵式打印机，用于通过横向移动的拖拉机（7,8）进给连续卷筒纸（6），这些拖拉机成对布置在打印机框架上。拖拉机销（9）接合到连续卷材（6）的边缘穿孔中，并且销带（10）被引导到拖拉机（7,8）的至少一个轮（11）上，并且至少一个从动牵引轮（13）存在。该装置配备有锁定装置，使得作为推动装置或拉动装置工作的拖拉机（7,8）在每种情况下安装在驱动轴（14）上，并且在每种情况下都防止打开打印机框架（1a））通过与驱动轴（14）相对的侧面（15a）上的突起（16）或摆动式拖拉机挡板（24）。
