Printing media feeding apparatus, printing apparatus provided with the feeding apparatus, printing media feeding speed control method and computer program

A printing apparatus comprising:

• a print head that prints visual data on printing media;
• feeding means 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 being rotated to feed the printing media;
• detection means that is provided in the drive shaft and detects the rotational speed of the drive shaft;
• and
• control means for controlling the motor,
• the control means controlling the motor based on an input from the detection means so that the rotational speed of the drive shaft becomes constant.

A printing media feeding apparatus comprising:

• 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 being rotated to feed the printing media;
• a detection section that is provided in the drive shaft and detects the rotational speed of the drive shaft;
• and
• a controller that controls the motor,
• the controller controlling the motor based on an input from the detection section so that the rotational speed of the drive shaft becomes constant.
