摘要

PROBLEM TO BE SOLVED: To provide an axial position adjusting device for an arm shaft of a paper roll mounting arm capable of sufficiently securing a mounting space of a slip ring device at a shaft end side of the arm shaft.;SOLUTION: This axial position adjusting device K2 rotatably and axially- movably supported on a frame F1 of a paper supply part, and mounted on the arm shaft 1 of the paper roll mounting arm rotated and driven by a rotating device K1 at one end side, is composed of a moving member 30 comprising a male screw 9, and being rotatably and axially-unmovably connected to the arm shaft; a guide member 40 comprising a threaded hole 16 engaged with the male screw of the moving member, and being rotatably and axially unmovably mounted to the frame; and a driving part 50 for rotating and driving the moving member. The moving member and the guide member are mounted in adjacent to a shaft rotating device, and the driving part is mounted on the supporting member axially-unmovably connected to the arm shaft.;COPYRIGHT: (C)2003,JPO
