摘要： A printhead assembly is used with a postage meter of the type having a base (4) supporting a main shaft (10) and a stepper motor drive (12). The stepper motor drive positions value rods (228) carried by the main shaft according to the value of the postage to be printed. The printhead assembly (14) includes a value module (16) mounted to an outer end (20) of the main shaft so to rotate with the shaft. A dater/slogan module (18) is also mounted to the outer end of the main shaft assembly and is positioned or indexed, such as using guide pins (56), to the value module. The components are housed within an enclosure including a separate printhead cover assembly (24). The printhead cover assembly includes an opening through which the field service personnel has access to the dater/slogan module to allow them to remove the dater/slogan module, such as for maintenance or repair, without affecting the security of the meter.

摘要： A postage meter stepper motor module (12) for use in a postage meter of the type having a base (4) supporting a rotatable main shaft (22) to which a printhead (14) is mounted. The main shaft has a number of value rods (228) mounted to it. The outer ends of the value rods are coupled to the printhead so movement of the value rods parallel to the main shaft axis changes the chosen value print character at the printhead. The stepper motor module includes a stepper motor frame (58) mounted to the base at a chosen position relative to the main shaft. A stepper motor (60) is mounted to the stepper motor frame. A yoke (212) couples the stepper motor to a chosen axial position along one of the value rods through a coupler ring (222). The coupler ring and yoke allow the value rod to rotate freely about the main shaft while maintaining the axial position determined by the stepper motor. The stepper motor and yoke are coupled by a rack (216) and pinion arrangement (202) to translate the rotary motion of the stepper motor to the linear motion of the yoke.
