摘要： In a print hammer assembly for a dot line printer, print pins are attached to the tip ends of print hammers alternately displaced toward left and right by a predetermined distance from a vertical center of the print hammer, wherein comb portions of a front yoke at both sides of the plunger are made to be an equal width. With such an arrangement, the print pins are not deformed horizontally due to imbalanced magnetic force applied to the associated print hammer at the time of magnetization of a permanent magnet.

摘要： A dot line printer having ink ribbon guides for stabilizing running performance of an ink ribbon. A dot line printer includes a hammer bank, a shuttle mechanism, a platen and ink ribbon guides. The hammer bank has print hammers for forming a plurality of dot impressions. The shuttle mechanism has one side positioned adjacent to one end of the hammer bank for reciprocally moving the hammer bank. The platen is adapted for bearing dot impression force, and a part of the ink ribbon is positioned at an ink ribbon path extending along the platen. The ribbon guides have a first guide positioned adjacent to another end of the hammer bank, and a second guide positioned adjacent to another side of the shuttle mechanism. The ink ribbon guides guide travel of the ink ribbon at the ink ribbon path. The ribbon guides further include a third ink ribbon guide positioned between the hammer bank and the shuttle mechanism for further guiding travel of the ink ribbon at the ink ribbon path.

摘要： Electromagnets and spring-damper units respectively impart forward movement and rearward movement to slider members having hammer faces at their forward ends and armatures intermediate their lengths. The electromagnets and spring-damper units are mounted by the frame of the print mechanism for independent longitudinal adjustive movement. Adjustive movement of the spring-damper assemblies effects lateral alignment of the hammer faces at the forward ends of the sliders. Adjustive movement of the electromagnets effects adjustment of the forward movement characteristics of the sliders. Clamping forces are preferably imposed upon the electromagnets pending and during their adjustive movement. Anchoring of the electromagnets in their final positions preferably is accomplished by laser welding. An inexpensive frame plate restrains lateral movement of the sliders, maintains desired spacing between the pole faces of confronting electromagnets, and provides a surface upon which adjustive movement of the electromagnets can readily occur.

摘要： A printing apparatus including a plurality of drive coils for driving printing hammers arranged longitudinally in side-by-side relation at one side of a core of the U-shape. A first cooling fluid passageway is defined inside the core of the U-shape to allow a cooling fluid for cooling the drive coils to flow therethrough, and a second cooling fluid passageway is defined outside the core by a duct to allow the cooling fluid for cooling the drive coils to flow therethrough without escaping to the outside by diffusion. A current of cooling fluid is forcibly fed into these cooling fluid passageways by a fluid machine.

摘要： A hammer bank assembly for use in line printers. The assembly includes an extruded metal rear frame having a uniform thickness and a plurality of machined mounting surfaces which are machined in accurate relationship with respect to one another. A pair of extruded plastic shoes are mounted to the top and bottom of the frame and also include machined surfaces for accurately aligning them with respect to the frame. The shoes include a plurality of mounting slots which are cut by means of a gang cutter. The slots serve to accurately align a plurality of print hammers in the shoes. The hammers are insulated with respect to the frame and the shoes in order to prevent sliding motion and subsequent wearing of the print hammers. Also disclosed are several methods of simplifying the construction procedure of the hammer bank assembly.

摘要： A printing device having a document feed path defined therein and a platen fixedly mounted adjacent the feed path, the platen having a plurality of character segments formed thereon. A plurality of impact members, there being at least one thereof for each character segment, are also positioned adjacent the document feed path and positioned thereat so that one of said impact members will strike one of the character segments. A spool-to-spool ribbon drive is adapted to position a print ribbon between the platen and the document in the feed path therefor and causes printing of each character segment where it is struck by an impact member. A document feed assembly is provided for moving each document along the feed path. Also provided is a control assembly operatively coupled between the document feed assembly and the impact members for selectively operating individual ones of the impact members in timed relationship to the motion of a document along the feed path to effect printing of selectable combinations of the character segments on the document.

摘要： In the printer, each printing hammer is composed of a pair of electroconductive elastic members arranged parallel to the axis of a type drum and is provided with paramagnetic material at its head. The hammer, when not used, is kept pulled in the non-printing position with the paramagnetic material attracted by a permanent magnet to accumulate mechanical energy in the elastic members. When the accumulated energy is discharged by an electromagnet provided at each hammer head including the paramagnetic material, printing operation is executed. Finishing the printing operation, the hammers return quickly to their home positions by the permanent magnet attraction force. A type drum and hammer heads are composed of an organic resilient substance.

摘要： The impact tip of the print hammer is provided with a curved face in one direction and shaped in a cylindrically-arcuate configuration. The impact tip is formed with the surface curvature in a direction perpendicular to the direction of character height and in a convexly curved or rounded manner as viewed from the type character. This structure of the impact tip together with an optimum chamfer angle of the type character permits closer spacing of the characters.

摘要： A printer mechanism is provided for adjusting the position of hammers when the relative distance between a type character and a print hammer is changed. The mechanism comprises a plurality of hammers driven toward a series of type characters which are continuously carried along the printing line to print characters on a record sheet interposed between said print hammers and type characters. The mechanism is designed such that said print hammers are shifted in the printing line so that the positions of respective hammers may be adjusted and correct printing is accomplished.
