Abstract

PURPOSE: To detect a malfunction such as a half rotation or the like of a letter wheel upon generation thereof by a method wherein magnets corresponding to each type are provided on a peripheral surface of the letter wheel and hall elements opposing to each letter wheel are provided at positions where feedings of the letter wheels are effected.
CONSTITUTION: Magnets 28 corresponding to respective types 26 are provided at an peripheral surface of a letter wheel 20 for a numbering instrumunt and hall elements 30 corresponding to rows of peripheral directions of a shaft 10 for the numbering instrument 14 are provided in a row in a direction of an axis of the shaft. When a half rotation or a rotation rotating with other letter wheels are caused in the letter wheel 20b, the hall element 30b generates a smaller voltage because the hall element 30 is not opposing to the magnet 28 of the letter wheel 20b in which the half rotation is being caused. When a signal from a detector 36 detecting a timing element 34 has come, the signal is sent to a comparator 40b through an AND circuit 38B, and if the signal voltage from the hall element 30b is lower than a standard voltage of the comparator 40b, a signal is generated from the comparator 40 and an alarming is effected by an alarm device 46.
