Abstract
An image recording apparatus includes a record unit; a first roller provided upstream of the record unit; a second roller provided downstream of the record unit; a motor which drives the first and second rollers; a first drive signal generation unit which generates a first drive signal based on a first rotation amount of the first roller and a first target rotation amount; a correction value generation unit which generates a correction value based on the first rotation amount and a second rotation amount of the second roller; a target value generation unit which generates a second target rotation amount based on the first target rotation amount and the correction value; a second drive signal generation unit which generates a second drive signal based on the second target rotation amount and the second rotation amount; and a controller which controls the motor by the first drive signal until a conveyed sheet reaches a position and controls the motor by the second drive signal thereafter.
