摘要:
There is disclosed a numbering machine designed so that code numbers as well as check digits each consisting of a single-place digit are printed by means of a mechanical mechanism. The check digits are printed by a check digit type wheel having an arrangement of circulating digits which are calculated in correspondance with code numbers in accordance with a modulus 10 or 11 check with predetermined weights. When there is a carry from one code number digit place to the next higher digit place, it is necessary to print the digit skipped a predetermined number of the digits in the circulating digit arrangement, and as a result a drive control mechanism is provided so that when a change from one code number to the next higher code number necessitates a skipping operation, the change is detected and the check digit type wheel is rotated idly through a predetermined angle.
