摘要： The ribbon (17) has an external run between the type element (25) and platen of a daisy-wheel typewriter. This run stretches between terminal members (59) which protrude from side arms (33 and 34) of the cartridge casing (18) and are fixed to the distal ends of arms (39, 41) pivotally mounted in the casing (18) at pivot (52). Ribbon lift levers of the typewriter raise the arms simultaneously to position a selected one of three tracks on the ribbon at the level of the typing. The ribbon is transferred from a feed spool having a flange to a take-up spool having a core tube and which are rotatably supported by the casing. The casing comprises a bottom portion having a resilient tongue with a pawl member positioned adjacent to the take-up spool and a resilient blade adjacent to the feed spool. The core tube of the take-up spool has a series of saw teeth and the pawl member cooperates with the saw teeth for enabling the rotary movement of the core tube in the direction of rewinding of the typing ribbon, but preventing rotary movement of the core tube in the other direction, while the resilient blade engages with peripheral notches at the flange of the feed spool. The casing further provides two apertures for housing a driving toothed wheel and a control lever of the typewriter which engage with the ribbon to control the feeding of the ribbon.

摘要： The ribbon (17) has an external run between the type element (25) and platen of a daisy-wheel typewriter. This run stretches between terminal members (59) which protrude from side arms (33 and 34) of the cartridge casing (18) and are fixed to the distal ends of arms (39, 41) pivotally mounted in the casing (18) at pivot (52). The arms (39, 41) are biased downwardly by wire springs (67) to expose the typing line. Ribbon lift levers of the typewriter raise the arms simultaneously to position a selected one of three tracks on the ribbon at the level of the typing point and a single drive shaft provides for the advancement of the ribbon. The cartridge comprises a feed spool and a take-up spool for the ribbon, a drive roller and a pressure roller which nip the ribbon internally to the casing, a transmission mechanism having a series of pinions and gears for transmitting the drive motion from the drive shaft of the typewriter to the pressure roller and to the take-up spool of the cartridge. A gear of the transmission mechanism is coaxial with the tke-up spool and is connected with the take-up spool by means of a friction clutch, which permits a slip motion between the gear and the take-up spool.

摘要： The ribbon (17) has an external run between the type element (25) and platen of a daisy-wheel typewriter. This run stretches between terminal members (59) which protrude from side arms (33 and 34) of the cartridge casing (18) and are fixed to the distal ends of arms (39, 41) pivotally mounted in the casing (18) at (52). The arms (39, 41) are biased downwardly by wire springs (67) to expose the typing line. Ribbon lift levers of the typewriter raise the arms simultaneously to position a selected one of three tracks on the ribbon at the level of the typing point. The terminal members (59) slide on guides (62) at the ends of the side arms (33, 34), constraining the external ribbon run to lie always within and translate within a single plane. The edges of the guides (62) are curved so that the tilt of the terminal members (59) varies as they move up and down, in such a way as to maintain the ribbon tension uniform across the width of the ribbon (17). The arms (39, 41) are flexible and have pivotal play to permit these constraints on the terminal members (59).
摘要翻译：带状物（17）在型式元件（25）和菊花轮打字机的压盘之间具有外部流动。这种运行在从盒壳体（18）的侧臂（33和34）突出的端子构件（59）之间延伸并且被固定到枢转地安装在壳体（18）中的臂（39,41）的远端 52）。臂（39,41）被线弹簧（67）向下偏压以暴露打字线。打字机的丝带提升杆同时抬起手臂，将打印点水平上的色带上的三个轨道中选定的一个放置在位置上。端子构件（59）在侧臂（33,34）的端部处的引导件（62）上滑动，限制外部色带运行，总是在单个平面内并在平面内平移。引导件（62）的边缘是弯曲的，使得端子构件（59）的倾斜度随着它们上下移动而变化，以使得色带张力在色带（17）的宽度上保持均匀。臂（39,41）是柔性的并且具有枢转播放以允许这些限制在终端构件（59）上。

摘要： A cartridge for an endless inked ribbon for printing office machines comprises a container in which are disposed separating elements which define a storage zone. An endless inked ribbon is disposed in loops and is distributed at random in the storage zone. The inked ribbon passes from a slit to the exterior of the storage zone and through one aperture to the exterior of the container. A section of the inked ribbon is twisted through 180.degree. to form a Mobius loop, by guide elements which localize the twisted section in a zone of the container outside the storage zone. The inked ribbon passes back into a container through a second aperture and returns to the interior of the storage zone through an opening thereof. At least one curved wall, adjacent to the slit, defines an housing for receiving any loop which have escaped from the slit for preventing a plurality of loops of the ribbon emerging simultaneously from the storage zone.
摘要翻译：用于印刷办公机器的无端墨带的墨盒包括：容器，其中设置有限定存储区的分离元件。无端着墨带设置在环中，并在存储区中随机分布。着色的色带从狭缝传送到存储区的外部，并通过一个孔到容器的外部。着色色带的一部分被扭转180度以形成Mobius回路，通过引导元件将扭曲部分定位在存储区外部的容器区域中。着墨带通过第二孔返回到容器中，并通过其开口返回储存区的内部。与狭缝相邻的至少一个弯曲壁限定了用于接收从狭缝逸出的任何环的壳体，用于防止从存储区同时出现的带的多个环。
