Claims

[Claims for Utility Model Registration] (1) A metering roller that is replaced with an ink cylinder in a key adjustment type inking device, and a cap on the ink rail of the inking device that is replaced with a pressure chamber; an ink rail having a pressure chamber; an ink removal device provided at a position separated from the ink rail; an ink pressurization supply means for supplying ink under pressure to an ink groove provided in the pressure chamber; and the ink pressurization. a press-fit application surface provided with a slight gap with respect to the circumferential surface of the metering roller in order to apply the ink supplied to the pressure chamber by the supply means to the circumferential surface of the metering roller; A tongue piece is attached to the chamber on the inlet side in the rotational direction of the metering roller, and the ink removing device is arranged to remove excess ink after being press-fitted onto the circumferential surface of the metering roller. A modified keyless inking device that is characterized by the ability to (2) The pressurized ink supply means is an ink circulation pump that circulates ink from an ink reservoir that receives surplus ink from the metering roller to the pressure chamber, and the pressure chamber is supplied from the ink circulation pump. 2. The modified keyless inking device according to claim (1), wherein the ink amount is controlled proportionally to the printing speed within a predetermined printing speed range from the start of printing.
