摘要： The invention is a mechanism for raising and lowering the ribbon in typewriters to make typed text visible. No separate drive such as a motor or magnet is required to raise the ribbon. The ribbon is raised by means of a spring-loaded bar prior to each character reproduction. To accomplish this, an armature of a control magnet releases a pivoting lever and the spring loaded bar. A pin wheel, driven by a motor and acting on the lever serves to return the bar and allow return of the ribbon. The motor is energized after each character reproduction to advance either a type element carrier or the paper carrier by one character space. In typewriters with ribbon spools fixed to the machine frame, the ribbon spool drive also can be derived from the spring powered bar.

摘要： Disclosed is a preferably transparent removably mounted cover plate for covering the top opening or printing point area in a printer, e.g. a needle printer, which serves to reduce noise and to prevent the introduction of foreign substances and dust. Of particular advantage is the inclusion on the cover plate of paper guide elements, a switch actuating cam which acts on a switch to shut off the machine when the cover plate is removed or swung out, and a paper tear-off edge.
摘要翻译：公开了一种优选地透明的可移除安装的盖板，用于覆盖打印机中的顶部打开或打印点区域，例如，针式打印机，用于降低噪音并防止引入异物和灰尘。特别的优点是在纸导板元件的盖板上包括开关致动凸轮，该开关致动凸轮在盖板被移除或摆动时作用在开关上以切断机器以及纸张撕开边缘。

摘要： An electromechanical printer having characters of a type font located on radial spokes of a circular type disc is disclosed. The type disc is normally arrested and connected to be driven about its axis by a unidirectional motor source via a slip clutch. Selection-print activating mechanism responsive to source, e.g. keyboard, generated mechanical outputs serve to select a character stop, in an assembly of character stops, corresponding to characters located on the spokes of the type disc and, incident to selection of a character stop, to release the normally arrested type disc. The type disc is provided with counterstops adapted to engage selected character stops positioned in the path thereof and to move the character stop assembly to a frame supported final positioning stop which arrests the type disc with the selected character opposite a print point. The encounter of the character stop assembly with the final positioning stop is employed to operate a print hammer to drive the selected character against a platen to print. Following printing, means are provided to reset selected character stops and to restore the character stop assembly to normal position.
摘要翻译：公开了一种具有位于圆形盘的径向轮辐上的类型字体的字符的机电打印机。型盘通常是通过滑动离合器被一个单向的马达源卡住并连接成围绕其轴线驱动的。响应于源的选择打印激活机制，例如。键盘，生成的机械输出用于选择字符停止，在与组件中的字符停止相对应的位于类型盘的辐条上的字符，并且选择字符停止，以释放正常停止的类型的盘。类型盘设置有反向挡块，其适于接合位于其路径中的所选择的字符挡块，并且将字符停止组件移动到支撑的框架的最终定位停止件，其阻止具有与打印点相对的所选字符的型式盘。使用具有最终定位止挡件的字符停止组件的碰撞来操作打印锤以将所选择的字符驱动抵靠压板以进行打印。打印后，提供了复位所选字符停止点并将字符停止组件恢复到正常位置的方法。
