| 20090283623 | RECORDING-PAPER-ROLL SUPPORTING DEVICE AND PRINTER - A recording-paper-roll supporting device includes first and second members. The first member includes an insertion portion, a supporting portion at an end of the insertion portion, and a support shaft at an end of the supporting portion. The supporting portion includes an outer peripheral surface, insertion-portion-side cam surfaces at different phases and heights, a collar portion, support-shaft-side cam surfaces at different phases and heights, and a cut section. The second member includes a cylindrical portion, a flange portion, a cam follower, and an engaging claw. When the outer peripheral surface is inserted along the inner peripheral surface and the cam follower and the engaging claw are selectively engaged with the insertion-portion-side cam surfaces and the support-shaft-side cam surfaces, the engaging claw is elastically deformed and generates a reactive force which presses the cam follower so that the second member is positioned on the supporting portion. | 11-19-2009 |
