<P>PROBLEM TO BE SOLVED: To provide a paper carrying mechanism and image forming apparatus, which enables stable and high-quality printing by eliminating displacement between the upper layer and the lower layer of continuous paper when the continuous paper, in which a plurality of layers are laid one upon the other, is wrapped around a cylindrical platen. <P>SOLUTION: The paper carrying mechanism includes: the platen 11; a carriage unit 20, including a printing head 22 facing the platen 11 and including a protector frame 23 for regulating a carrying passage for continuous paper 15 carried near the printing head 22; a holding means 56 for holding the carriage unit 20 such that the carriage unit 20 is movable in the axial direction of the platen 11; and an idle roller 16, disposed on an upstream side from the carriage unit 20 in the direction in which the continuous paper 15 is carried, and determining the angle at which the continuous paper 15 is wrapped around the periphery of the platen 11 together with the protector frame 23. Further, the holding means is configured to hold the carriage unit 20 such that the carriage unit 20 is rotatable around the shaft of the platen 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
