Groove 344a is moved to the second translation groove 344b, and now, the pivot of separation member 34 is in the second translation groove 344b rotation
Heart N.Because 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
Translation groove 344a pivot M is moved to the second translation groove 344b pivot N.
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 now 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, holding is also just fixed in the position of separation member 34 by support column 35, 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 embodiment of the present invention, engaged to ensure that the second gear 141b completely disengages with teeth portion 331, between described first
The distance that gap g1 and the support column 35 move, i.e., the first translation groove 344a pivots M and the second translation groove 344b rotate
The distance between center N LMNMeet：LMN＞ g1.
As described above, counting mechanism 30 of the present invention has the after the completion of first position and counting before counting
Two positions, in first position, the counting part 31 is coaxial with separation member 34；In the second place, the counting part 31 and separation member
34 is not coaxial, i.e., at first position, the rotation axis L1 of counting part 31 is conllinear with the rotation axis L4 of separation member 34, second
During position, the rotation axis L1 for counting part 31 is not conllinear with the rotation axis L4 of separation member 34.Specifically, at first position,
Support column 35 is in the first translation groove 344a, and at the second place, supporting pillar 35 is in the second translation groove 344b, due to flat
Move in groove 344 and be provided with across portion 345, therefore, crossed when support column 35 from the first translation groove 344a across portion 345 and be moved to the
After two translation groove 344b, in the case where not acted on by external force, support column 35 would be held in the second translation groove 344b；Together
When, the distance between the first translation groove 344a pivots M and the second translation groove 344b pivots N LMNMeet：LMN＞
G1, thus, second gear 141b can completely disengage with teeth portion 331, even if Delevoping cartridge P receives external impacts, because power connects
