    • A scanning pen (10) is used in combination with a transparent ruler (36) which guides the movement of the pen (10) over a line of text. An indicia bar (46 and 50) along the length of the ruler (36) independently establishes the time rate in which the pen (10) is manually moved independent of whether the pen (10) is advanced, stopped, or reversed to generate a pixel map. A dictionary (208) of different symbols is established for identification of scanned graphic patterns. The scanning pen (10) may be used either as a point-and-click bar code reader (222), a bar code scanner (224), mouse (218), handwritten data (220), or text data input device (216). Bar codes may be user-defined or standardized and may symbolize alphanumeric data or macro instructions. The scanning pen (10) uses a single linear detector array (52) which can either be used in either a stationary input mode, a linear scan mode, or a two-dimensional mode. In the two-dimensional mode, a timing grid (228) with horizontal (232) and diagonal timing bars (234) of distinguishable thicknesses is employed to track the manual movement of the scanning pen (10).
    • 扫描笔(10)与透明标尺(36)组合使用,该标尺将笔(10)的移动引导到文本行上。 沿着标尺(36)的长度的标记杆(46和50)独立地建立笔(10)被手动地移动的时间速率,而不管笔(10)是前进,停止还是倒转,以产生 像素图。 建立了不同符号的字典(208),用于识别扫描图形。 扫描笔(10)可以用作点击式条形码读取器(222),条形码扫描器(224),鼠标(218),手写数据(220)或文本数据输入装置(216) )。 条形码可以是用户定义的或标准化的,并且可以表示字母数字数据或宏指令。 扫描笔(10)使用单个线性检测器阵列(52),其可以在静态输入模式,线性扫描模式或二维模式中使用。 在二维模式中,使用具有可区分厚度的水平(232)和对角定时杆(234)的定时网格(228)来跟踪扫描笔(10)的手动移动。
