ABSTRACT:
An ink fountain apparatus includes a plurality of ink blade segments which are arranged in a row extending in the axial direction of a ink fountain roller to form an adjustable ink supplying port between the ink blade segments and the peripheral surface of the ink fountain roller, and an adjusting mechanism provided for each of the ink blade segments to adjust the degree of opening of the ink supplying port. The adjusting mechanism includes a spring which forces the ink blade segment to retract away from the ink fountain roller, a press rod which contacts the rear end of the blade segment at its forward end and is provided with a cam follower facing toward the direction of retracting movement of the blade segment, and an end cam member which is rotatable about a rotational axis parallel to the direction of movement of the blade segment and has a cam surface which is in contact with the cam follower. The drive/transmission means mechanically coupled with the end cam member has a rotational axis parallel to the rotational axis of the end cam member. With this structure, the total size of the ink fountain apparatus and space needed for installing the ink fountain apparatus can be reduced.
