PROBLEM TO BE SOLVED: To provide a feeding mechanism capable of moving among each of dents without depending upon the thickness and interval of the dents.SOLUTION: This feeding mechanism is provided by including a base plate part 31 of which rotary shaft 34 is in parallel to the orienting direction of the dents, a rotary plate 30 extended from the base plate part 31 and having a guiding part 32 of which tip end can be displaced in the orienting direction (X-axis direction) of the dents, and a displacement-adjusting means 40 for displacing the tip end of the guiding part 32 in the X-axis direction by making a contact with the guiding part 32 temporarily in the process of rotating the rotary plate 30 by a predetermined angle to make the guiding part 32 spiral toward the surface of the base plate part 31 and also freely adjusting the displacing amount of tip end of the guiding part 32, and by rotating the rotary plate 30 by a predetermined angle, and inserting the tip end of the displaced guiding part 32 into between the dents, which is different from the between the dents in which the part of the base plate part 31 is inserted, so as to move the base plate part 31 between the different dents by following the guiding part 32 as accompanying with the rotation of the rotary plate 30. |
