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 said 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 said gear so as to rotate the gear and increase the count by only one in the count number display.本發明係提供一種供給裝置之計次機構,係使用於在每一次的旋轉操作,將儲藏在儲藏室的儲藏物以單次供給量供給至外部的計次機構,以簡單的構造來計次儲藏物的供給次數,可掌握不能目測的裝置內部之儲藏物的殘量。本發明之計次機構係具備有:固定在供給裝置本體,且在圓周方向的特定位置上具有凸輪部的固定構件(10);具有可從外部觀看的計次數顯示之齒輪(20);以取得容許供給單次供給量的儲藏物之旋轉方向的位置、和阻止供給儲藏物之位置的方式,加以旋轉限制的旋轉構件(40);與該旋轉構件連動,可旋轉地且在圓周方向的特定位置上,具有爪之可彈性變形的凸輪的從動部之環狀構件(30)。旋轉構件在進行一次的供給操作量的旋轉之間,藉由前述凸輪部與凸輪的從動部間的凸輪作用,使爪與齒輪扣合,使齒輪僅旋轉計次數顯示的1顯示量。
