摘要： An apparatus and method are disclosed for determining the position and angular velocity of a print drum. The apparatus includes a detector that is positioned proximate to the drum, and a processor coupled to the detector. The drum has a cylindrical body with a plurality of alphanumeric characters and a sequence of marks, including an index mark and a plurality of timing marks uniformly disposed about the circumference of the body, the timing marks being in relative alignment with the characters such that each character is associated with a pair of timing marks. The index mark is used to designate a start or reference location on the body. The detector includes a magnetic field generating source such as a magnet, a magnetic lens for directing the field toward the marks, and a hall effect sensor for detecting (through changes in magnetic field caused by the marks when the drum is rotated) the index mark and respective pairs of the timing marks, and producing a digital signal representative of the detected marks. In response to the digital signal, the processor detects a pair of timing marks and determines the position on the drum of the character associated with the detected pair. The processor also determines the angular velocity of the drum based on frequency of detection of the timing marks.
摘要翻译：公开了一种用于确定打印鼓的位置和角速度的装置和方法。该装置包括靠近滚筒定位的检测器，以及耦合到检测器的处理器。滚筒具有圆柱体，其具有多个字母数字字符和一系列标记，包括索引标记和围绕身体周围均匀设置的多个定时标记，定时标记与字符相对准，使得每个字符与一对定时标记相关联。索引标记用于指定身体上的起始或参考位置。检测器包括诸如磁体的磁场产生源，用于将场引导到标记的磁性透镜，以及用于检测（通过滚筒旋转时由标记引起的磁场变化）的霍尔效应传感器，和相应的定时标记对，并且产生表示检测到的标记的数字信号。响应于数字信号，处理器检测一对定时标记并确定滚筒上与检测到的对相关联的字符的位置。处理器还基于定时标记的检测频率来确定滚筒的角速度。

摘要： A control system for operating a single high-speed print wheel is disclosed. The control system includes a print wheel drive motor having a coded disc with transparent portions forming a four-level Gray code for indicating the position of the print wheel. An optical and electronic system is used for positioning the print wheel and also for the purpose of providing an electronic detent which uses the motive power of the print wheel drive for holding the print wheel in selected printing positions. A similar optical and electronic system is used for controlling a paper advance mechanism. The disclosed system also includes a print hammer with a voice coil type drive to permit positive, bidirectional hammer control.
摘要翻译：公开了一种用于操作单个高速打印轮的控制系统。该控制系统包括具有编码盘的打印轮驱动马达，该盘具有形成用于指示打印轮位置的四级格雷码的透明部分。光学和电子系统用于定位打印轮，并且还用于提供使用打印轮驱动器的动力的电子制动器，用于将打印轮保持在选定的打印位置。类似的光学和电子系统用于控制纸张提前机制。所公开的系统还包括具有音圈型驱动器的打印锤，以允许正双向锤控制。

摘要： A compact flying printer has a continuously rotating print drum and ratchet wheel, a trigger lever positionable to be struck by a tooth of said ratchet wheel and a hammer lever driven by said trigger lever and provided with a print hammer at its end. The trigger lever is formed with a linear guide portion for regulating the motion thereof and an energy-transmitting portion projected for transmitting energy from said ratchet wheel to said hammer level. Paper and ribbon are advanced by selective coupling of a transmitting member to a continuously rotating rotor operated in conjunction with the print drum.

摘要： A high-speed serial printer including a continuously rotating print drum having characters on its periphery, a hammer and carrier, and a belt for transporting the hammer and carrier parallel to the axis of drum along a line of print. A control system, including two timing discs, operates in synchronism with the drum. The first disc is indicative of the angular position of the drum and the second disc is to signal the hammer carrier to engage the transport belt at the start of each line of print. A double-ended transducer responds to the two timing discs to provide the appropriate signals for the printer.
