    摘要： The invention relates to a needle printing head (1) comprising a number of printing units (2). Each printing unit (2) is provided with a spring (9) supporting an armature (6) and a printing needle (10). The armature (6) is included in a magnetic field path comprising both a permanent magnet (4) and an electromagnet (7) provided with a core (8). Each spring (9) has one rigidly fastened end and one freely swinging end. According to prior art needle printing heads, the springs are so fixed that essentially the hole bending takes place in one single point in direct connection to the rigidly fastened end. This puts high requirements upon the spring material and the risk of material fatigue is great. According to the invention the bending of the spring (9) does not take place in one signal point, but it distributed along at least a first length adjacent to the fastening point. This distributed fastening is obtained by means of a supporting means (5.1) disposed on the side of the spring facing the electromagnet between the fastening point and an end of the core of the exciting coil (8) disposed in connection to the armature (6).

    摘要翻译： 本发明涉及一种包括多个打印单元（2）的针头打印头（1）。 每个印刷单元（2）设置有支撑电枢（6）和印刷针（10）的弹簧（9）。 电枢（6）包括在包括设置有芯（8）的永磁体（4）和电磁体（7）的磁场路径中。 每个弹簧（9）具有一个刚性紧固的端部和一个自由摆动的端部。 根据现有技术的针式打印头，弹簧被固定，使得基本上孔弯曲发生在与刚性紧固的端部直接连接的一个单一点上。 这对弹簧材料有很高的要求，材料疲劳的危险性很大。 根据本发明，弹簧（9）的弯曲不是在一个信号点发生，而是沿至少一个与紧固点相邻的第一长度分布。 这种分布式紧固是通过一个支撑装置（5.1）来获得的，所述支撑装置（5.1）设置在面向电磁体的弹簧的一侧，紧固点和与电枢（6）连接设置的励磁线圈（8）的芯部的端部之间， 。

    摘要： Power driven type action in electric typewriter comprising a power driven rotary toothed snatch roll continuously rotated during operation, a pivotally mounted actuating lever connected to driven members including a type bar, spring biased engage member provided to move on the actuating lever having a pawl engageable with a tooth of the snatch roll, and an intermediate lever provided on the actuating lever. Depression of a key lever causes the intermediate lever to rotate to engage the intermediate lever with the engage member. Thereby the engage member is rotated and the pawl thereof is engaged with a tooth of the snatch roll, so that the engage member, intermediate lever and actuating lever are rotated together by the snatch roll. Thus printing operation is performed.
