Claim Text:
1. A printer comprising: a roll supporting part configured to rotatably support a print-receiving tape roll, wherein the print-receiving tape roll includes a print-receiving tape in a rolled shape; a feed roller configured to pull out and feed the print-receiving tape included in the print-receiving tape roll supported by the roll supporting part; a printing head configured to print on the print-receiving tape that is pulled out and fed from the print-receiving tape roll by the feed roller; and an urging device configured to slide to and contact an outer peripheral surface of the print-receiving tape in the rolled shape and to elastically press the print-receiving tape roll supported by the roll supporting part while the print-receiving tape is pulled out and fed from the print-receiving tape roll, wherein the roll supporting part is a roll containing part configured to rotatably contain the print-receiving tape roll, wherein the printer further comprises at least one support roller in the roll containing part, the at least one support roller being configured to, when the print-receiving tape is pulled out and fed from the print-receiving tape roll by the feed roller, rotate by contacting the outer peripheral surface of the print-receiving tape in the rolled shape and rotatably support the print-receiving tape roll, wherein the roll containing part contains the print-receiving tape roll such that the print-receiving tape is pulled out and fed from an upper side of the print-receiving tape roll, wherein the print-receiving tape is pulled out and fed from the print-receiving tape roll at a feeding out position, wherein the feeding out position is located nearer to a position where the urging device contacts the outer peripheral surface of the print-receiving tape in the rolled shape than to a center of the print-receiving tape roll, wherein the at least one support roller comprises three rollers, wherein as the print-receiving tape is pulled out and fed from the print-receiving tape roll, the outer peripheral surface of the print-receiving tape in the rolled shape has a diameter in a range from a maximum diameter to a minimum diameter, wherein at least two rollers of the three rollers are arranged such that the at least two rollers continuously contact the outer peripheral surface of the print-receiving tape in the rolled shape when the diameter is in the range from the maximum diameter to the minimum diameter, wherein the three rollers are arranged in an order of a first roller, a second roller, and a third roller from the feeding out position in a direction extending from the feeding out position toward an opposite side of the print-receiving tape roll from the feeding out position, wherein the second roller and the third roller are substantially horizontal to each other, and the first roller is located above the second roller and the third roller, and wherein the feeding out position is located nearer to the position where the urging device contacts the outer peripheral surface of the print-receiving tape in the rolled shape than to the first roller.
