摘要： A needle printing head comprising a support (11) able to axially guide a plurality of printing needles (15), each of which has one end attached to a mobile armature (16) of a corresponding actuation electromagnet (17) having a ferromagnetic core (18) provided with polar extensions. A separation element (30) is interposed between the mobile armatures (16) and the corresponding polar extensions. The separation element (30) is made of a metal material and comprises elements (33, 34) able to reduce the effects of the eddy currents which are generated by the energizing of every electromagnet (17).

摘要： Hitherto impact dot printers have encountered problems of short circuiting between the printed circuit board (9) and the solenoid coil (16); accurate positioning of the nose (1) and the frame (2); providing adequate heat dissipation to allow high speed printing; and providing sufficient damping at the coil terminal (12)/pcb (9) junction to allow for vibrations caused by printing.
All of the above problems have been obviated by providing a partial or complete circumferential wall (27, 27a) on the spacer member (8) and a rotational locking mechanism (28, 25, 24, 26, 23, 33) between the frame (2), spacer member (8), pcb (9) and nose (1).

摘要： A printer head consists of a yoke (11), magnet members (12) mounted to the yoke, a base plate (14) attached to the front of the yoke (11), and a plurality of head pins (17) provided between the yoke (11) and the base plate (14). In this printer head, the head pins (17) are arranged in straight rows, which are inclined at a specified angle to the direction of stroke of the printer head. The base plate (14) is formed with a plurality of through- holes (18) at positions corresponding to the head pins so that the head pins can be advanced and retracted through the through-holes (18) by the action of the magnet circuit.

摘要： In a wire dot print head in which each of armatures (2) are attracted toward a core (9) to resiliently deform a plate spring (3) when an associated coil is not energized, and is released and moved forward by the action of the plate spring when the coil is energized, with the rear surface of the armatures (2) being kept in contact with the front end of the fulcrum members; a partition sheet is disposed between the rear surfaces of the armatures and the front ends of the cores and the front ends of the fulcrum members to interrupt transfer of fluid, and to prevent direct contact between the cores and the fulcrum members, and the armatures. The partition sheet comprises a front plastic film (14), a metallic residual sheet (13), a rear plastic film (15) which are stacked in the stated order from the front side to the rear side; and the front film (14) is bonded to the metallic residual sheet (13) over the entire surface of the metallic residual sheet. By bonding the front film and the metallic residual sheet, migration of grease (20) from the rear side to the front side of the partition sheet is prevented, and adhesion of the grease component to the plate spring is also prevented. Moreover, because of the bonding, the metallic residual sheet (13) is prevented from contacting the air and hence from rusting.
摘要翻译：在一个丝网印刷头中，其中每个电枢（2）被吸引到芯（9），以在相关的线圈不通电时使板弹簧（3）弹性变形，并且通过线圈通电时的板簧，电枢（2）的后表面与支点构件的前端保持接触; 在电枢的后表面和芯的前端以及支点构件的前端之间设置隔板，以阻止流体的传送，并且防止芯与支点构件和电枢之间的直接接触。分隔板包括从前侧到后侧按顺序堆叠的前塑料膜（14），金属残留片（13），后塑料膜（15）并且在金属残留片材的整个表面上将前膜（14）接合到金属残留片材（13）。通过接合前膜和金属残留片，防止了从分隔板的后侧向前侧的润滑脂（20）的迁移，并且还防止了润滑脂组分与板簧的粘合。此外，由于接合，防止金属残留片（13）与空气接触，从而防止生锈。

摘要： A wire dot printing head comprises armatures (1) each of which is coupled to a printing wire (12), a felt guide for reducing the friction between the printing wire and the printing wire guide, a residual sheet (10) is disposed over a magnetic core frame (8), a biasing leaf spring (9), and an oil leakage preventing chip (19). The chip (19) is disposed over the armatures (1) to prevent oil oozing from the felt guide. An errorneous dot printing operation due to the stick between the armatures (1) and the residual sheet (10) is prevented.

摘要： In an embodiment of this invention, a carriage (31) includes the first lever that is operated by an operator to attach to or detach from a printhead (70) and rotates about the first rotating shaft (M). The carriage also includes the second lever that rotates about the second rotating shaft (S) parallel to the first rotating shaft and, if the printhead is attached, contacts part of the printhead and presses the printhead in accordance with the rotation. The carriage further includes a spring (60) having one end hung on an end portion of the second lever and the other end hung on part of the carriage. If the printhead is attached, the press force of the spring acts to press the printhead against the carriage in accordance with the rotation of the first lever. If the printhead is detached, no press force acts.
摘要翻译：在本发明的一个实施例中，托架（31）包括由操作者操作以附接到打印头（70）或从打印头（70）脱离并围绕第一旋转轴（M）旋转的第一杠杆。滑架还包括第二杠杆，该第二杠杆围绕平行于第一旋转轴的第二旋转轴（S）旋转，并且如果打印头被附接，则第二杠杆接触打印头的一部分并且根据该旋转来按压打印头。所述滑架还包括弹簧（60），所述弹簧的一端悬挂在所述第二杆的端部上，另一端悬挂在所述滑架的一部分上。如果安装了打印头，则弹簧的按压力根据第一杆的旋转而将打印头压向滑架。如果打印头脱落，则不会有压力作用。

摘要： A construction of dot matrix print head is disclosed in which a plurality of body elements (16), each carrying print wire actuators (22, 23), are arranged in stacked formation. The body elements (16) and the arrangement of actuators 922, 23) is identical so that by offsetting the body elements (16) relative to adjacent body elements (16), print wires (30) actuated by actuators of one body member (16) are inter-digitated with print wires (30) actuated by actuators of a body member (16) adjacent said one body member. This construction permits the actuators to be accommodated in a print head of relatively small transverse dimensions.
