Coating device and liquid discharge apparatus

Abstract

A coating device includes a conveyor, a driver, circuitry, and a digital-to-analog converter. The conveyor includes a coating roller to coat a medium with a liquid while conveying the medium in a conveyance direction. The driver rotates the coating roller at a rotation speed. The circuitry outputs a speed command value as a digital value. The digital-to-analog converter converts the speed command value as the digital value into an analog voltage value. Further, the circuitry calculates a correction amount to correct the speed command value, reflects the correction amount in the speed command value when the medium is not passing through the coating roller, and applies the speed command value, as the analog voltage value corrected by the correction amount, to the driver to rotate the coating roller at the rotation speed to convey the medium.
