摘要:
In a setting device for presettable counters, a number of indicating rollers are arranged with symbols on their circumferential peripheral surfaces. Connected to each indicating roller is a ratchet wheel and an adjusting wheel. A switching device for each roller permits it to be moved in a step-by-step manner and otherwise to be locked in position. The switching device includes a switching pawl for engaging the ratchet wheel and moving the roller, a fixing lever for locking the adjusting wheel and roller in position, a control pawl and a key for displacing the control pawl. The control pawl is spring-biased against the actuating movement of the key. The control pawl displaces the switching pawl and the fixing lever in response to its displacement by the key.
