ABSTRACT:
In the stepping or indexing drive of a character drum having secured thereat a pinion, wherein there is provided an actuation plunger for rotary motion of the pinion in the one direction and another actuation plunger for rotary motion of the pinion in the other direction, there must be prevented that the character drum while rotating from one index position to the next can be stopped and remain in an intermediate position between two index positions. For this purpose, there is provided a movable locking or detent element which coacts with both actuation plungers and with inclined surfaces formed at the switch housing. This locking or detent element is brought by each individual actuation plunger, at the start of its actuating path, into a locking position for the other actuation plunger and retained in this locking position to positively prevent simultaneous actuation of both actuation plungers.
