摘要： The invention contemplates a document printer for the automatically indexed sequential account numbering of successive documents, with the added feature of printing alongside each sequential number an automatic indication of the validity or invalidity of the number printed, said indication being a "check digit" which, in conjunction with the printed account number, renders the printed account number self-checking. The invention is described in application to weighted-modulus self-checking systems of the Modulus 10 and Modulus 11 varieties, inter alia.
摘要翻译： 本发明设想一种文件打印机，用于对连续文件进行自动索引的顺序帐号编号，其中附加打印特征与每个序列号一起自动指示所打印的数字的有效性或无效性，所述指示是“校验数字” 结合打印的帐号，显示打印的帐号自检。 本发明在应用于模量10和模量11品种的加权模量自检系统中被描述。
