Claims

[Scope of utility model registration request]

Ink source roller 1 on the front side, ink weir 2, 2
', and the rear and bottom surfaces are respectively closed by the inclined bottom plate 3, and a large number of prismatic ink keys 6 are closely connected between the lower side of the bottom plate 3 and the upper surface of the base plate 7. In an ink fountain device of a printing press, which is arranged side by side in a state where the ink fountains are moved forward and backward toward the outer peripheral surface of the ink source roller 1, a fulcrum is installed at a position behind each ink key 6 and is moved forward and backward by hand. holder 8, a rack 17 fixed to a movable bush 9 installed below the fulcrum holder 8 and moved forward and backward by an operating lever 28 via gears 29 to 33, and a fulcrum shaft 11 attached to the front end of the fulcrum holder 8. an eccentric cam 13 which is rotatably supported by an eccentric cam 12; a idler ring 12' which is rotatably attached to the outer periphery of the eccentric cam 12; a gear 10 meshed with,
The same ink key 6 attached to each ink key 6
Eccentric wheel 13 is provided with a spring 36 that keeps its rear end surface in pressure contact with the outer periphery of idler ring 12', and is displaced by the rotation of gear 10 due to the forward and backward movement of rack 16.
An ink fountain device for a printing press, characterized in that the ink supply amount is adjusted by the operation of the fulcrum holder 8, and the zero point is adjusted by moving the fulcrum holder 8 back and forth.
