    摘要： A tabulator mechanism for an office machine, such as a typewriter, in which the tabulator rack is mass fabricated by a simple manufacturing process, and the tabulating stops are of an inexpensive construction. The stops can be easily mounted or removed from the tabulator rack. Furthermore, the tabulator mechanism construction is not only inexpensive but effectively achieves the desired function.

    摘要： Apparatus for implementing the tabulating function on a typewriter or communications printer terminal. An opaque cylinder is provided which rotates in synchronism with the relative movement between the printing mechanism and the recording medium. The cylinder wall is perforated with a series of holes along a line of rotation and sliding shutters in the cylinder wall may be selectively displaced to either block a hole or allow the passage of light therethrough. The holes correspond to character spaces, or print columns. A light source and a phototransducer are aligned so that when a hole is clear, the phototransducer produces a signal in response to light impinging thereon from the light source. The shutters are displaceable by two hammers, one on each side of the cylinder. One of the hammers displaces the shutters into the ''''tab clear'''' position and the other hammer displaces the shutters into the ''''tab set'''' position. Receipt of a ''''tab'''' signal causes the apparatus to search for a hole which has its associated shutter displaced to the ''''tab set'''' position.

    摘要翻译： 用于在打字机或通信打印机终端上实现制表功能的装置。 设置不透明圆筒，其与打印机构和记录介质之间的相对运动同步旋转。 气缸壁沿着旋转线穿孔一系列孔，气缸壁中的滑动快门可选择性地移动以阻挡一个孔或允许光通过其中。 这些孔对应于字符空间或打印列。 对准光源和光电转换器，使得当孔清晰时，光电转换器响应于从光源入射到其上的光产生信号。 百叶窗可以通过两个锤子移动，一个在圆筒的两侧。 其中一个锤子将百叶窗移动到“突片清除”位置，另一个锤将百叶窗移动到“标签组合”位置。 接收“标签”信号使得设备搜索具有相关联的快门位移到“标签设置”位置的孔。

    摘要： A paragraph indentation mechanism for a typewriter which has an escapement mechanism for controlling the letter-spacing movement of the carriage and which includes a rack mounted on the carriage and also a member pawl mounted on a frame for both pivotal and limited sliding movement in a carriage traveling direction. A special key is operatively connected to the member pawl and the escapement mechanism for engaging the member pawl with the rack and then disabling the escapement mechanism so as to move the carriage with the member pawl. By this mechanism, the carriage is moved in a letter-spacing direction a number of spaces, for example five, from any position where the carriage is retained by the escapement mechanism.
