SUPPORTING STRUCTURE FOR SUBSTANTIALLY CYLINDRICAL MEMBER, ROLL PAPER HOLDER AND LABEL PRINTER

摘要

PROBLEM TO BE SOLVED: To provide a label printer capable of using both of inwardly wound roll paper and outwardly wound roll paper with hardly generating paper jamming, and a supporting structure of a substantially cylindrical member and a roll paper holder to be used in the label printer. SOLUTION: In this supporting structure, each of a pair of walls 11 opposed to the end face of the roller paper includes a projection part 22 arranged in the cylinder of the roll paper to support the roll paper and a projecting part 13 for fixing a position arm 2 to either one of an upper position and a lower position so that the projection part 22 may have substantially the same horizontal position and a different vertical position.
