Patent ID: 8920054

Claim:
A roll tape comprising: a core main body portion which includes an inner core portion and an outer core portion that extends further axially outwards than the inner core portion and which has a larger diameter than a diameter of the inner core portion; a pair of shaft portions each including (i) an outer shaft of which at least part of an outer circumference thereof is fittingly inserted into the outer core portion, (ii) an insertion portion that is concentric with the outer shaft and which projects further in a first direction than the outer shaft so that at least part of a circumference thereof is fittingly inserted into the inner core portion, and (iii) a bearing shaft that is concentric with the outer shaft and which projects further in a second direction opposite to the first direction than the outer shaft; and a printing tape which is wound around an outer circumference of the outer core portion of the core main body portion, wherein the pair of shaft portions are coupled with the core main body portion from both axial sides thereof for integral connection; and wherein the outer core portion has an axial length which corresponds to a tape width of the printing tape, and the inner core portion has an axial length which is substantially equal to a sum of axial lengths of the pair of insertion portions, irrespective of the axial length of the outer core portion.
