    • A ribbon cartridge includes two hubs, each hub having two sets of longitudinally extending splines. The two sets are offset from each other circumferentially and longitudinally and form a detent between the sets. A latch mechanism includes a retaining member fixed to a mandrel assembly, the retaining member including first and second pairs of elastic locking members having raised surfaces. The raised surfaces of one of the pairs of locking members engage the detent formed between the first and second sets of hub splines, and the raised surfaces of the other pair of locking members engage a spindle of the mandrel assembly, effectively securing the ribbon cartridge to the mandrel assembly.
    • 色带盒包括两个轮毂,每个轮毂具有两组纵向延伸的花键。 两组在周向和纵向彼此偏移,并在两组之间形成一定位。 闩锁机构包括固定到心轴组件的保持构件,保持构件包括具有凸起表面的第一和第二对弹性锁定构件。 一对锁定构件中的一个的凸起表面接合形成在第一组和第二组轮毂花键之间的制动器,另一对锁定构件的凸起表面接合心轴组件的心轴,有效地将色带盒固定到 心轴组件。

    • An improved thermal ribbon cassette is detachably mounting to a thermal printing postage meter. The thermal ribbon cassette has an opening, a plurality of posts. Some of which posts are located to each side of the opening, a take-up spool and a supply spool rotatively mounted in the housing, and a thermal ink transfer ribbon supply wrapped around the supply spool and extending to the take-up spool threaded from and between the post and extending through the opening. The opening is located to receive a thermal print head therein such that the transfer ribbon traverses below the print element of the thermal print head. Slots are formed in the respective forward and rear wall, a first post to the take-up side of the aperture is positionably mounted in the slots such that the angle downstream of the opening may be selectively changed.
    • 改进的色带盒可拆卸地安装在热敏打印邮资计费器上。 该色带盒具有开口,多个柱。 其中一些柱位于开口的每一侧,卷取卷轴和可旋转地安装在壳体中的供应卷轴,以及缠绕在供应卷轴上的延伸到卷取卷轴的热转印色带供给, 并且在柱和延伸通过开口之间。 开口被定位成在其中接收热敏打印头,使得转印带横过热敏打印头的打印元件下方。 狭槽形成在相应的前壁和后壁中,到孔的卷绕侧的第一柱可定位地安装在槽中,使得可以选择性地改变开口下游的角度。

    • Apparatus is disclosed for use with printers (or plotters) for storing and transferring ink-containing ribbon cassettes between a print head and a storage location. The printers (or plotters) are of the type which include a print head that is not as wide as the width of the medium to be printed on so that the print head has to be moved to print (or plot) across the full width of the medium. The apparatus automatically removes a cassette mounted to the movable carriage to which the print head is also mounted and deposits it in the storage station, and automatically removes a selected cassette from the storage station and deposits it on the print carriage. The apparatus includes cassette holders at the storage location and a cassette holder mounted to the print carriage. The storage station is positioned in or adjacent the path of travel of the print carriage, and the apparatus holding the cassettes at the storage station may be indexed to position a particular cassette holder into alignment with the cassette holder mounted to the carriage. The cassette holders have cooperating structure which automatically engage each other when the holders are aligned and are moved one into the other to automatically and directly transfer a cassette from one holder to the other.
    • 公开了与打印机(或绘图仪)一起用于在打印头和存储位置之间存储和转移含墨色带盒的设备。 打印机(或绘图仪)的类型包括打印头不如要打印的介质的宽度那么宽,以便打印头必须被移动以打印(或绘制)横跨整个宽度的 介质。 该装置自动移除安装在可移动托架上的盒体,打印头也安装在该盒体上,并将其存放在存储站中,并自动从存储站中移除所选择的盒子并将其存放在打印托架上。 该装置包括在存放位置的盒座和安装在印刷架上的盒座。 存储站位于打印托架的行进路径中或其附近,并且将保存在存储站处的盒的设备可以被索引,以将特定的盒座定位成与安装到托架的盒座保持一致。 盒保持器具有协作结构,当保持器对准并且一个一个地移动到另一个中时自动地彼此接合,从而将盒从一个保持器自动地直接传送到另一个。
