Abstract:
The present invention prevents density irregularity from appearing in a print result and to thereby improve image quality by controlling a motor so that the rotational speed of a drive shaft that feeds printing media is constant. The present invention provides a printing media feeding apparatus including a feeding section that includes a motor, a drive transmission mechanism which transmits a driving force of the motor, and a drive shaft to which the driving force is transmitted by the drive transmission mechanism. The drive shaft is rotated to feed the printing medium. A detection section is provided having at least a portion secured to the drive shaft and the detection section determines the rotational speed of the drive shaft and a controller controls the motor based on an input from the detection section so that the rotational speed the of the drive shaft is constant.
