    • 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。
