Heart N.Since support column 35 is fixed on housing, thus, support column 35 does not become with respect to the position of drive gear 141
Change, but separation member 34 is changed with respect to the position of drive gear 141, specifically, the pivot of separation member 34 is by first
The pivot M of translation groove 344a is moved to the pivot N of the second translation groove 344b.
Continuing as shown in figure 13e, counting mechanism 30 is completed after counting, and closest approach of the cam 341 from contact site 141c is T,
The distance between pivot N and closest approach T of separation member 34 at this time are LNT, the LMQWith LNTMeet：LMQ＞ LN.Branch
The diameter d of dagger 35 is more than described two spacing h across between portion 345, therefore, when support column 35 translates groove 344a from first
After being moved to the second translation groove 344b, in the case where no external force acts on, support column 35 will be limited in the second translation groove
In 344b, without returning the first translation groove 344a, the position of separation member 34 is also just supported column 35 and fixes holding, and then,
The position of the power reception part 33 combined with separation member 34 is also just fixed to keep, the teeth portion 331 on the power reception part 33 with
Position between second gear 141b is also fixed and held.
In the utility model embodiment, engaged to ensure that the second gear 141b is completely disengaged with teeth portion 331, described
The distance that one gap g1 and the support column 35 move, i.e., the first translation groove 344a pivots M and the second translation groove 344b
The distance between pivot N LMNMeet：LMN＞ g1.
As described above, after the completion of counting mechanism 30 described in the utility model is with the first position before counting and counting
