    • An inkribbon feed mechanism is disclosed which feeds the inkribbon by utilizing power of a spacing motor by which a print head is transversed. The inkribbon feed mechanism comprises commanding means which detect a command element for reversing the inkribbon near one end of the inkribbon, an arm member which interlocks with the command means via a spring member and is pivotably supported by a pivot, a planetary gear member which is provided at one end of the arm member and is rotated by the power of the spacing motor via a drive gear member. In compliance with the alternate rotation of the spacing motor, the planetary gear member engages with a gear member of one reel or is slightly moved in orbit by the drive gear member so as not to render a rotational force to the reel. The arm member is pivoted by the command means to change the object which the planetary gear engages.
    • 公开了一种墨水输送机构,其通过利用间隔电动机的功率来馈送墨迹,打印头通过该功率被横切。 墨水输送机构包括:命令装置,其检测用于反转墨迹的一端附近的墨迹的指令元件;臂构件,其经由弹簧构件与指令装置互锁并且由枢轴可枢转地支撑;行星齿轮构件, 设置在臂构件的一端并​​且经由驱动齿轮构件通过间隔电动机的动力而旋转。 根据间隔马达的交替旋转,行星齿轮构件与一个卷轴的齿轮构件接合或者被驱动齿轮构件稍微移动到轨道中,以便不向卷轴施加旋转力。 臂构件通过指令装置枢转以改变行星齿轮接合的物体。

    • Upon writing, a portion of light emitted from light-emitting devices of a light-emitting and light-receiving head 2 is deflected by a half mirror and is then allowed to pass through a first lens array to achieve optical writing on a rotating or moving photoreceptor. Upon reading, on the other hand, light reflected by an original is allowed to pass through a second lens array and then to enter the half mirror. The light is then allowed to pass through the half mirror to the light-emitting and light-receiving head 2 and is hence read by reading devices of the light-emitting and light-receiving head.It is therefore possible to perform writing and reading while the light-emitting and light-receiving head and the optical system remain stationary. No mechanism is therefore needed for moving the light-emitting and light-receiving head, thereby making it possible to provide a scanner-equipped electrophotographic printing machine having small dimensions and high resolution.
    • 在写入时,由发光和受光头2的发光装置发射的光的一部分被半透半反镜偏转,然后被允许通过第一透镜阵列以实现旋转或移动的光学写入 感光器。 另一方面,读取时,由原稿反射的光被允许通过第二透镜阵列,然后进入半反射镜。 然后允许光通过半反射镜到达发光和光接收头2,因此通过读取发光和光接收头的装置来读取。 因此,可以在发光和受光头和光学系统保持静止的同时执行写入和读取。 因此,不需要用于移动发光和光接收头的机构,从而可以提供具有小尺寸和高分辨率的装有扫描仪的电子照相印刷机。

    • A serial printer head is provided which comprises a sandwich structure (1,3,5) of a first circular yoke plate (1), a cylindrical magnet (3) and a ring shaped second yoke plate (5); a plurality of electromagnets (2,4) positioned on the first yoke plate (1) at predetermined angle intervals; an armature-print-needle assembly (7,8,9,10) having a circular resilient spring (7), a plurality of armatures (8) and a plurality of print needles (9) placed on the sandwich structure (1,3,5) so that the sandwich structure (1,3,5), electromagnets (2,4) and the armatures (8) provide first a substantially closed magnetic path; and an adjusting yoke (12) attached to the sandwich structure (1,3,5). The adjusting yoke (12) has the magnetic characteristics that the magnetic reluctance increases as the temperature increases. Although the flux generated by the permanent magnet (3) is changed due to the change of the temperature, that flux change is compensated for by the presence of the adjusting yoke (12).
    • 提供一种串行打印机头,其包括第一圆形磁轭板(1),圆柱形磁体(3)和环形第二磁轭板(5)的夹层结构(1,3,5)。 多个电磁体(2,4),其以预定的角度间隔定位在所述第一磁轭板(1)上; 具有圆形弹性弹簧(7)的电枢印刷针组件(7,8,9,10),放置在夹层结构(1,3)上的多个电枢(8)和多个印刷针(9) ,5),使得夹层结构(1,3,5),电磁体(2,4)和电枢(8)首先提供基本封闭的磁路; 以及安装在所述夹层结构(1,3,5)上的调节轭(12)。 调节磁轭(12)具有随着温度升高磁阻增加的磁特性。 尽管永磁体(3)产生的磁通量由于温度的变化而改变,但通过调节磁轭(12)的存在来补偿磁通变化。

    • A small printer is provided which comprises a housing, a rolled printing paper mounted in the housing, a platen along which a paper runs, a motor, and a carriage having a printing head for mosaic printing on a paper on the platen. The carriage travels along the whole width of the paper and is driven by the motor, and a paper transfer mechanism transfers the paper by one line for every traverse of the carriage. The paper transfer mechanism comprises an idler positioned beneath the path of the paper, the idler being swingable in the moving direction of the paper, and the idler having a first projection parallel to the path of the carriage at the left half of the idler and a second projection inclined to the path of the carriage at the right half thereof. The projections are engaged with the corresponding slots provided at the bottom of the carriage to ensure the swing movement of the idler is synchronized with the movement of the carriage. The idler has a substantially V-shaped friction member providing a large frictional force to the paper in the normal moving direction of the paper and a small frictional force to the paper in the opposite moving direction of the paper.
