摘要： Ribbon cassettes for typewriters or office machines of similar construction are subject to differnt structural requirements and primarily they are to be easily exchangeable in a one-hand operation. Since additionally the ribbon cassettes are also designed as disposable components, many still functional individual parts are also discarded. To avoid this, ribbon cassettes are known which have exchangeable ribbon spools. It is the object of the invention to provide a reloadable ribbon cassette in which the exchange of ribbon spools (4, 5) is possible with few manipulations. The removal of the spent ribbon spools (4, 5) should here be possible without soiling the fingers. This problem is solved in that the take-up spool (5) and the supply spool (4) are arranged to be freely placeable onto bearing pins (11, 12) in the bottom member (6) and the movable parts for guiding and transporting the ribbon (8) in the bottom member (6), which has a cup-shaped configuration, are mounted on one side and, except for the take-up spool (5) and the supply spool (4) which are freely placeable onto the bearing pins (11, 12), are arranged to be arrestable against falling out of the cassette housing if the cover (2) is open. This permits exchange of the ribbon spools (4, 5) with few manipulations without the operator performing this exchange soiling his/her fingers. The exchange of ribbon spools (4, 5) is also possible for less experienced operators not having special skills.

摘要： A ribbon cassette for an office machine, composed of: a cassette housing removably mountable in the machine, the housing having an entrance opening, an exit opening, an openable cover and elements constituting deflection points; a supply spool and a take-up spool having a core, each of the spools being removably mounted in the cassette housing; a carbon ribbon initially wound in the form of a coil on the supply spool, the ribbon having a leading end at the outer surface of the coil to be received by the take-up spool core to permit the ribbon to be wound up on the take-up spool while being unwound from the supply spool; and a fastening member secured to the leading end of the ribbon for threading the ribbon around the deflection points; and wherein the core is formed for enabling the fastening member to be fixed thereto to aid winding of the ribbon on the take-up spool.

摘要： A reloadable ribbon cassette system for typewriters or office machines of similar construction employs a bottom housing in which an exchangeable supply spool core for the ribbon and an exchangeable take-up spool core can be rotatably mounted. To facilitate the reloading process a cover plate is placed onto the top face of the ribbon coiled on the supply spool core, the cover plate inserted into the bottom housing member along with the supply spool core and ribbon when they are loaded. The cover plate has a contact surface for helping to steady a fastening element disposed at the free end of the ribbon during reloading. The cover plate projects beyond the ribbon coil at least in the region of the contact shelf to prevent accidental removal of the first few turns of the coiled ribbon in axial direction. The cover plate unequivocally gives a starting point for a guide pin which is detachably connected to the fastening element, the guide pin being used for threading the ribbon around a ribbon path to the take-up spool core.
摘要翻译：用于具有相似结构的打字机或办公机器的可重新加载的色带盒系统采用底壳，其中用于色带的可更换供应卷轴和可更换的卷取卷轴芯可旋转地安装。为了便于重新加载过程，将盖板放置在卷绕在供应卷轴芯上的色带的顶面上，盖板当它们被装载时与供给卷轴芯和带一起插入到底部壳体部件中。盖板具有用于帮助稳定在重新加载期间设置在带的自由端处的紧固元件的接触表面。盖板至少在接触架的区域突出超过带状线圈，以防止螺旋带的前几匝在轴向方向上的意外移除。盖板明确地给出了可拆卸地连接到紧固元件的引导销的起点，该引导销用于将带状物沿着带状通道卷绕到卷取卷轴芯。

摘要： A reloadable ribbon cassette system for typewriters or office machines of similar construction employs a housing which receives an exchangeable supply spool for the ribbon and an exchangeable take-up spool core. To facilitate the reloading process, the take-up spool core is mounted in the housing on a bearing pin which extends upward from a contact surface. The take-up spool core has a bearing bore into which the bearing pin extends and a bearing surface which rests on the contact surface. The contact surface is disposed closely below a receiving bore in the take-up spool core which accommodates a fastening element attached to the end of the ribbon.
