Counter mechanism of feeding device and feeding device using such counter mechanism

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 () fixed to the body and having cam lobes formed in circumferential direction, a gear () having a count number display that can be monitored from the outside, a rotating member () 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 () 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. The rotating member is operated for a single feeding operation, the jaw of the resilient cam follower is engaged with the gear so as to rotate the gear and increase the count by only one in the count number display.
