<p>A mailing machine (10) includes a postage meter (16) and a housing (14) for supporting the postage meter (16), and means for individually feeding sheets (20) in a path of travel (22) through the machine (10). The postage meter (16) includes rotary means (24) for printing indicia on the sheets (20) and a roller (66) spaced downstream in the path of travel (22) from the rotary printing means (24). The sheet feeding means includes an impression roller (60) and a shaft (61) on which the impression roller (60) is mounted for rotation therewith; an ejection roller (62) and a shaft (63) on which the ejection roller (62) is mounted for rotation therewith; and an elongated carriage (67) including a pair of side walls (67A) spaced apart from each other, one end of each of the side walls (67A) including an arcuately-shaped portion (67C) pivotally attaching the carriage (67) including a pair of side walls (67A) spaced apart from each other, one end of each of the side walls (67A) including an arcuately-shaped portion (67C) pivotally attaching the carriage (67) to the housing (14) and forming a generally C-shaped bearing bushing. The ejection roller (62) shaft (63) is rotatably mounted within the bearing bushings for supporting the ejection roller (62) beneath the postage meter roller (66) and the impression roller (60) is rotatably connected to the carriage side walls (67A) for supporting the impression roller (60) beneath the rotary printing means (24). A spring (68) connects the other end of the carriage (67) to the housing (14) to permit the carriage (62) to pivot downwardly about the ejection roller shaft (63) against the force exerted by the spring (68) as the ejection roller shaft (63) rotates within the bearing bushings, thereby permitting mixed thickness sheets (20) to be individually fed between the rotary printing means (24) and impression roller (60).</p> |
