  • Patent number: 7819285
    Abstract: In a counter mechanism of a feeding device, in each discrete feeding operation, an amount corresponding to single delivery unit of stored material is ejected and providing a simple construction and permitting the remaining amount of stored material in the device invisible from outside to be known by counting the number of delivered units of stored material. A counter mechanism of this invention comprises a fixed member (10) fixed to the body and having cam lobes formed in circumferential direction, a gear (20) having a count number display that can be monitored from the outside, a rotating member (40) being restricted to rotate either to a position in the rotating direction to allow feeding of a single delivery unit and a position to preventing feeding of the stored material, a ring member (30) which can rotates in interlock with the rotating motion of the rotating member and comprises a resiliently deformable cam follower having a jaw formed at a predetermined position in circumferential direction.
