    • A postage meter resetting apparatus includes a stepper motor (61) as a first motive arrangement for turning the resetting shaft (85) of a mechanical postage meter (20), another stepper motor (69) as a second motive mechanism to enable or disable resetting by the first stepper motor. A lead screw (98), lead nut and linkage, driven by the second stepper motor, when resetting is authorized, moves an axially movable part of a coupling between the second stepper motor and the meter's axially movable resetting shaft, to bring the resetting gear (87) on the shaft into engagement with a gear (93) of the meter's descending register. An input to the first stepper motor (61), representing a variable amount of postage, effects turning of the resetting shaft (85) and the engaged gears by amounts corresponding to the desired variable amount of postage to be added to the meter's descending register (39). An encoder (64) coupled to the shaft of the first stepper motor provides an output indication of the amount that the shaft has turned. A CPU routine assures that the gear on the meter's resetting shaft has cleared a blocking pin (89) and engaged the descending register gear prior to resetting by the first stepper motor. Another CPU routine clears jams when it is detected that the shaft has not been turned the amount desired.
    • 一种邮资计复位装置包括用于转动机械邮资计(20)的复位轴(85)的第一动力装置的步进马达(61),作为第二动力机制另一个步进电机(69)来启用或禁用重置 第一步进电机。 导螺杆(98),引导螺母和连杆,由所述第二步进电机驱动,当复位被授权,移动使第二步进电机和仪表的可轴向移动的复位轴之间的联接器的可轴向移动的部件,所述复位齿轮 (87)在所述轴成与仪表的递减寄存器的一个齿轮(93)。 (一个输入到第一步进电机(61),表示邮资可变量的,要添加到仪表的递减寄存器效果转动复位轴(85)和通过量对应于邮资的期望变量的啮合齿轮的 39)。 耦合到所述第一步进电机的轴的编码器(64)提供有关量的输出指示做的轴已经转向。 甲CPU例程确保做了仪表的复位轴上的齿轮已经清除了阻挡销(89)和由所述第一复位步进电机之前接合的递减寄存器齿轮。 当检测,DASS模具轴处理不当被接通希望的量的另一种常规CPU清除卡纸。
