As in fig. 8d, return unit 212 is rotated to the 3rd position shown in Fig. 8 D, specifically, the 3rd position refers to
Service portion 213 departs from combination with resetting contact site 164.Now, a part for service portion 213 remains at imaginary circles C scope
Interior, when applying to after the directed force F revocation of forced section 212, return unit 21 will be acted on next time in the restoring force of the second elastic component 23
To first position, and the second elastic component 23 applies restoring force to return unit 21 always so that return unit 21 is always held at first
Position.
As described above, return unit 21 has three below position：
First position, rotation of the return unit 21 to counting gear 16 does not form interference, now, at the entirety of return unit 21
Outside the scope of the imaginary circles C；
The second place, the service portion 213 of return unit 21 starts to be combined with resetting contact site 164, now, the service portion
213 are partly into imaginary circles C；
3rd position, the service portion 213 of return unit 21 departs from combination, now, the service portion with resetting contact site 164
213 part is remained in the range of imaginary circles C.
When return unit 21 works, the first position, the second place and the 3rd position are undergone successively, and be eventually returned to first
Position, thus, return unit 21 is after the reset of counting gear 16 is completed, the rotation carried out when will not again be counted to counting gear 16
Turn to cause interference.After Delevoping cartridge D of the present invention completes to assemble, at least a portion in the return unit 21 is exposed to the
