Elektromagnetischer Zaehler

摘要

An electromagnetic counter for digitally counting applied signal pulse numbers, including resetting mechanism for simultaneously resetting a series of digit wheels to their zero position. Actuating force for the resetting mechanism is applied to a rockable first lever, which has the same number of resetting arms as that of the digit wheels for rotating them to zero position and a lever arm for rotating a rotatable frame supporting a series of pinions engaged between each of the digit wheels into pinions' disengaging position. There is provided between the lever arm of the first lever and the rotatable frame a second lever pivoted at its respective ends to them for transmitting the actuating force. The pivoting point of the first lever, respective pivoting points between the first and second levers and the second lever and rotatable pinion frame are substantially aligned on a straight line so as to make repulsing torque given to the pinions from the digit wheels to be small.
