ABSTRACT:
A zero-restting type of counter comprising a plural number of digit wheels supported on the same shaft and having digit-shift pins, driven gears arranged between individual pairs of said digit wheels, intermittent transmission mechanisms for coupling the individual digit wheels with the corresponding driven gears, digit-shift pins and pinions engaged with said driven gears.
Said counter is adapted in such a manner that rotation of said driven gears caused by rotation of said pinions is transmitted by way of said intermittent transmission mechanisms to said digit wheels for the counting operation, whereas said intermittent transmission mechanisms do not transmit rotation and only said digit wheels are rotated when these wheels are rotated for resetting at the zero positions.
