PURPOSE:To realize the residual type preset counter excellent in the operability with simple construction, by linking the cam gear with the set or count wheel through the switching of cover, in a preset counter providing the counter wheel and set wheel. CONSTITUTION:On the shafts detached up and down and in parallel with each other, counter wheels 10-13 and set wheels 17-20 are provided and cam gears 61-64 are provided among them, and the shaft of the cam gears is selectively shaken to 2 positions with the switching of the cover 93, so that the cam gear can be linked to the set wheels 17-20 or count wheels 10-13. Thus, the numeral to be set can always be confirmed with the numeral on the set wheel. Thus, any body can confirm the set value on its way other than people in charge. Further, complicated slip mechanism is not given to the counter wheels, cam gears and set wheels, allowing easy construction and high durability. The set operation is very simple and no misoperation can be expected. |
