COUNTER MECHANISM OF FEEDER AND FEEDER HAVING COUNTER MECHANISM

摘要

A counter mechanism of a feeder for feeding a stored material stored in a storage chamber to the outside in increments of single feed amount for each rotating operation capable of detecting the residual amount of the stored material in invisible devices by counting the number of times of feeding of the stored material by a simple structure. The counter mechanism comprises a fixed member (10) fixed to a feeder body and having a cam part at a specified position in the circumferential direction, a gear (20) having a count number indicator visible from the outside, a rotating member (40) rotatingly restricted so as to be positioned in the rotating direction to allow the feeding of the stored material by a single feed amount and positioned in the rotating direction to stop the feeding of the stored material, and a ring member (30) rotatable in association with the rotating member and having an elastically deformable cam follower part having a claw at a specified position in the circumferential direction. The claw is engaged with the gear by a cam action between the cam part and the cam follower part while the rotating member is rotated for a single feed amount to rotate the gear by only one scale on the count number indicator.
