置。[Claims for Utility Model Registration] A first object that is slidably equipped with an applicator roll that is pressed against a conveyed steel strip, and a pick-up roll that picks up and coats the paint in the paint pan on the applicator roll. a pedestal, a second pedestal attached to the downstream side of the roll housing and slidable via an elevating means in the direction of bringing the first pedestal into contact with and away from the steel strip; a pressing force adjustment mechanism provided between the pedestal and the first pedestal to adjust the pressing force between the steel strip and the applicator roll; and a pressing force adjustment mechanism between the pressing force adjustment mechanism and the first pedestal. A device for controlling the coating film of a roll coater, which is equipped with a pressing force detector installed between the steel strip and the applicator roll, and a pressing force calculator for calculating the standard pressing force between the steel strip and the applicator roll; a comparator for comparing the pressure with a pressing force signal from the pressing force detector; and a first dead band circuit provided in parallel on the output side of the comparator and having a narrow dead band into which the signal from the comparator is input. and a second dead band circuit having a wide dead band, and a switching circuit that selects and switches the output signals from these first and second dead band circuits and outputs them to a drive control device that drives the pressing force adjustment mechanism. A coating film control device for a roll coater characterized by:
