Patent ID: 7621518

Claim:
An image recording apparatus comprising: a record unit which records an image on a record medium conveyed in a conveying direction in a conveying passage; a first roller which is provided upstream of the record unit in the conveying direction in the conveying passage; a second roller which is provided downstream of the record unit in the conveying direction in the conveying passage; a motor which drives the first roller and the second roller; a drive transmission mechanism which transmits a drive force of the motor to the first roller and the second roller; a first detection unit which detects a first rotation amount of the first roller; a second detection unit which detects a second rotation amount of the second roller; a storage unit which stores a first target rotation amount; a first drive signal generation unit which generates a first drive signal based on the first rotation amount detected by the first detection unit and the first target rotation amount stored in the storage unit; a correction value generation unit which generates a correction value based on the first rotation amount detected by the first detection unit and the second rotation amount detected by the second detection unit; a target value generation unit which generates a second target rotation amount based on the first target rotation amount stored in the storage unit and the correction value generated by the first correction generation unit; a second drive signal generation unit which generates a second drive signal based on the second target rotation amount generated by the second generation unit and the second rotation amount detected by the second detection unit; and a controller which controls the motor by the first drive signal until the conveyed record medium reaches a predetermined position in the conveying passage and controls the motor by the second drive signal after the conveyed record medium reaches the predetermined position.
