Patent ID: 8090469

Claim:
A printing medium conveying apparatus that is configured to move a printing medium in a sub scanning direction, the apparatus comprising: a drive pulley including a rotatable shaft; a belt arranged over the drive pulley and configured to rotate in correspondence with a rotation of the rotatable shaft; a motor configured to move the printing medium by rotating the rotatable shaft; and a control unit that includes a speed profile and is configured to calculate the rotation of the rotatable shaft and control the moving of the printing medium through feedback control using the speed profile; wherein the speed profile includes an accelerating region, a constant speed region, a decelerating region, a constant low speed region, and a stopping operations region; the speed profile is switched from the accelerating region to the constant speed region according to speed information; and the speed profile is switched between the constant speed region, the decelerating region, the constant low speed region, and the stopping operations region when a current position of the motor reaches a predetermined distance from a target position.
