摘要： An apparatus for securing a typewriter, includes a locking device for locking an outer case in a closed position and a fastening device for fastening a bottom plate of the case to a mounting base. When opened, the cover permits a portion of the bottom plate to be exposed. The fastening device is brought, from inside the case, into engagement with the bottom plate of the case through the exposed portion of the bottom plate, thereby locking the typewriter to the mounting base. The fastening device for the bottom plate cannot be released unless the locking device is unlocked by a key to open the cover. Accordingly, only a keyholder can unlock the locking device, thus preventing the typewriter from being stolen. Further, since the fastening device is engaged with the bottom plate of the typewriter case, the outer appearance of the typewriter is not degraded.
摘要翻译：一种用于固定打字机的装置，包括用于将外壳锁定在关闭位置的锁定装置和用于将外壳的底板紧固到安装基座的紧固装置。当打开时，盖子允许底板的一部分露出。紧固装置从壳体内部通过底板的暴露部分与壳体的底板接合，从而将打字机锁定到安装基座。用于底板的紧固装置不能被释放，除非锁定装置被钥匙解锁以打开盖子。因此，只有钥匙扣可以解锁锁定装置，从而防止打字机被盗。此外，由于紧固装置与打字机壳体的底板接合，所以打字机的外观不会降低。

摘要： A mounting head is used to fix a print wheel to the free end of a drive shaft provided on a carrier. The head extends from the print wheel toward a platen. The head lies in a space defined by the print wheel and a document guide device which is located between the platen and the print wheel and which guides a document downward in front of the platen. A document is not blocked by the mounting head while it is guided through the gap between the platen and the document guide device.
摘要翻译：安装头用于将打印轮固定到设置在托架上的驱动轴的自由端。头部从打印轮朝向压板延伸。头部位于由打印轮和文档导向装置限定的空间中，文档引导装置位于压板和打印轮之间，并且将原稿向下引导到压板前方。当文件被导引通过台板和文件引导装置之间的间隙时，文件不被安装头阻挡。
