Outer-peripheral-wall abutment surfaces and inner-peripheral-wall abutment surfaces of armatures having respective sections disposed to be drawn opposite to the core sections are formed to be coextensive with each other. Core-section opposed surfaces of the sections to be drawn are formed coextensive with the outer-peripheral-wall abutment surfaces and the inner-peripheral-wall abutment surfaces. In another aspect of the invention, the core-section opposed surfaces are so formed as to be depressed toward a side opposite to the core sections.

摘要： An improved print head for a dot matrix printer is provided. The printing is performed by wires projecting from said print head. The movement of the wires is controlled by the movement of armatures which contact an armature base. The construction of the base from a liquid crystal polymer or an aromatic series polyester resin results in improved vibration damping which in turn results in quieter printer operation.

摘要： A printing head includes solenoids arranged in an annular array for driving needles which are arranged in a zigzag array of two vertical columns. Solenoids corresponding to needles forming one of the columns are arranged on a semicircle of the annular array in the same order as that of the needles on the needle column. Two solenoids respectively corresponding to needles disposed at lower ends of the two needle columns are designed to generate magnetic fluxes whose directions are the same. During underline printing where these two solenoids are alternately energized, the magnetic flux generated by one of the solenoids never acts to increase an effective magnetic flux of the other solenoid at an initial stage of the excitation period thereof, so that the needle of the first solenoid reaches its forwardmost position at an appropriate time. The needle is rapidly restored and its tip prevented from being caught by the ink ribbon. After the forwardmost position is reached by the needle associated with the first solenoid, the magnetic flux generated by the second solenoid never acts to increase the magnetic flux of the first, permitting rapid restoration of the needle.
摘要翻译：打印头包括布置成环形阵列的螺线管，用于驱动针布置成两个垂直列的之字形阵列。对应于形成一个柱的针的螺线管以与针柱上的针的顺序相同的顺序布置在环形阵列的半圆上。分别对应于设置在两个针列的下端的针的两个螺线管被设计成产生方向相同的磁通量。在这两个螺线管交替通电的下划线打印期间，其中一个螺线管产生的磁通量在其激励周期的初始阶段从不会增加另一个螺线管的有效磁通，使得第一螺线管在适当的时候到达最前面的位置。针快速恢复，其尖端防止被墨带卡住。在与第一螺线管相关联的针到达最前面的位置之后，由第二螺线管产生的磁通不会增加第一螺线管的磁通量，从而允许针的快速恢复。

摘要： A gap adjusting device moves a print head vertically via a carriage shaft eccentrically supported by a displacement gear. The displacement gear is provided with a gap lever, which restricts rotational movement of a driving force transmission mechanism by abutting on a stop when a pulse motor drives the print head to move away from a platen. The pulse motor becomes out of phase, thereby defining the position as a reference position. The amount of rotation of the pulse motor is adjusted, starting from the reference position, thereby adjusting a vertical position of the print head. The reference position of the print head is established without the risk of causing damage to dot pins, by defining the initial condition of the pulse motor.
