PROBLEM TO BE SOLVED: To dispose with a spring provided on an ink key, and thus effect prevention of an ink leakage and lowering of driving power force by directly connecting an ink key and an eccentric wheel in an ink fountain device. SOLUTION: The apparatus includes a fulcrum holder 8 provided at the rear part of each ink key 6 and being movable forward and rearward, and a rack 9 disposed vertically and being movable forward and rearward similarly. A partially broken toothed gear 10 is axially supported rotatably at the front of fulcrum holder 8 by a support shaft 13, and the teeth 11 of the partially broken toothed gear and the teeth of the rack 9 are permitted to be in an engaged state, and also there is provided a semicircular hole part made at the rear part of an ink key 6 being slidably pivoted at the outer circumference of an eccentric wheel 14 being slightly eccentrically set from the center of a support shaft 13 put on the partially broken toothed gear 10. In this manner, by rotation of the partially broken toothed gear 10 through forward and rearward movement of the rack 9, the ink key 6 is adjusted in its forward and rearward movement. |
