Abstract
A printing medium feeding apparatus comprises a conveying belt, on which a roll-shaped printing medium is placed with the lower surface of the roll being in contact therewith to unwind the outer periphery of the roll. With the arrangement, setup of the roll to the feeding apparatus is completed easily by only placing the roll onto the conveying belt, as compared with a construction in which the center of a roll is rotatably supported. It is also possible to omit or simplify a transmission mechanism such as a train of reduction gears that is necessary for the case of central driving. Further, it is also possible to feed a constant amount of length at a constant drive speed irrespective of radius of the roll.
