    • A photocomposing system wherein each character is assigned a character width as it is selected, with the character widths being accumulated in a line length memory as the line is composed to create a measure of the minimum length of the line, and with the minimum line length being deducted from the desired line length and the excess space distributed between words of the line to create lines of substantially uniform length, includes apparatus permitting errors in composition to be corrected on a word-by-word basis. The one word error system includes a word length memory for accumulating the widths of characters in each word including the width of the preceding word space as they are selected, with the word length memory being reset with the beginning of each word space. When an error in composition is detected in a word being typed, the word length memory is used to restore the line length memory to its condition prior to the previous word space, so that the errored word and space can be deleted and corrected without recomposing the entire line.
    • 一种光电系统,其中每个字符被分配为被选择的字符宽度,其中字符宽度被累积在线长度存储器中,因为线被构成以创建线的最小长度的度量,并且具有最小线长度 从期望的行长度中扣除并且分配在线的字之间的多余空间以产生基本上均匀的长度的线,包括允许在逐个字基础上校正组合中的错误的装置。 一字错误系统包括一个字长存储器,用于在每个单词中积累包括先前字空间的宽度的字中的字符宽度,其中字长存储器用每个单词空间的开头复位。 当在被输入的字中检测到合成中的错误时,使用字长存储器将行长存储器恢复到先前字空间之前的状态,从而可以删除和纠正错误的字和空格,而无需重新组合 全线
