Zero-reset type counter

A zero-reset type counter comprising a frame;

• a supporting shaft mounted on said frame;
• a plurality of digit wheels rotatably mounted on said supporting shaft, each of said digit wheels having a first annular recess formed with an internal gear on its inner perpheral face on one side thereof and having a second annular recess formed respectively with an eccentric cam on its center portion and order shift teeth on its inner peripheral face on another side thereof;
• a rotary shaft rotatably mounted on said frame adjacent to said plurality of digit wheels;
• a plurality of zero reset levers secured on said rotary shaft and interposing respectively between a pair of said digit wheels adjacent each other and engageable to said eccentric cam;
• a pinion rotatably mounted on said each zero reset lever and engageable with said internal gear;
• and an order shift pinion so mounted on said each zero reset lever as to be able to rotate integrally with said pinion and engageable with said order shift teeth, the digit wheel of higher order being turned by one numeral through said order shift teeth and order shift pinion when said pinion is meshed with said internal gear and the digit wheel of lower order adjacent to said digit wheel of higher order is fully rotated at counting, and said each zero reset lever being turned in order to simultaneously let said pinion disengage from said each internal gear and said each order shift pinion from said each order shift teeth and to simultaneously and forcibly rotate said each digit wheel to the zero indicating position through said each eccentric cam at zero resetting.
