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 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 typing device has a type disc which includes a plurality of bars each carrying a character and which is rotatable about an axis through predetermined angles for successively setting selected characters in a printing position. The typing device further has a hammer for impacting the bar of the selected character for pressing the selected character against a record carrier supported by a platen. The type disc carries a plurality of stops; each stop is assigned to a different character. The stops are arranged at least at two different distances from the disc axis, dependent upon the printing surface area of the associated character. The typing device further has an elastic lever, one end of which is movable into an abutting engagement with the stop of the associated character situated in the printing position. Another end of the elastic lever is connected to the hammer so that the hammer and the elastic lever are moved simultaneously by a hammer drive. The elastic lever is arranged to absorb, upon engagement with the respective stop, one part of the kinetic energy imparted by the hammer drive for reducing the force with which the character is pressed against the record carrier. The amount of the absorbed kinetic energy is a function of the distance of the respective stop from the disc axis.
摘要翻译：打字装置具有类型盘，其包括多个条，每个条都带有字符，并且可绕轴线旋转预定角度，以在打印位置中依次设置所选择的字符。打字装置还具有用于冲击所选字符的条的锤，用于将所选择的字符压靠在由压盘支撑的记录载体上。型盘带有多个挡块; 每个停靠点被分配到不同的角色。取决于相关联的字符的打印表面区域，止挡件至少与盘轴线的两个不同距离被布置。打字装置还具有弹性杆，弹性杆的一端可移动成与位于打印位置的相关联的人物的挡块相邻接。弹性杠杆的另一端连接到锤子，使得锤和弹性杆通过锤驱动同时移动。弹性杠杆布置成在与相应止动件接合时吸收由锤驱动器施加的动能的一部分，以减少角色被压靠在记录载体上的力。吸收的动能的量是相应止挡件与盘轴的距离的函数。
