PROBLEM TO BE SOLVED: To stabilize behavior of a recording medium in delivery of the recording medium to a conveyor belt mechanism on the downstream side to a conveyor belt mechanism on the upstream side. SOLUTION: When paper P conveyed by a conveyor belt 38A of the conveyor belt mechanism 302 is delivered to a conveyor belt 38B of the conveyor belt mechanism 304 on the downstream side, a front end of the paper turns downward. An angle at which the front end of the paper P turns downward are determined according to printing coverage (printing area ratio on the recording medium), type of the paper P, feeding speed of the paper P, size of the paper P. The angles at which the front end turns downward is calculated by combining one or the plurality of such conditions, a paper feeding frame is turned and a downward gradient is set on the conveyer belt 38B based on the result of the calculation. Even if the front end of the paper P turns downward, since the conveyor belt 38B on the downstream side has the downward gradient in relation to the conveyor belt 38A on the upstream side according to the angles at which the paper P turns downward, the paper P is naturally conveyed without correcting posture of the Paper P. Consequently, since behavior of the paper P is stabilized and the paper P is conveyed smoothly, tilting, jamming or the like are prevented. COPYRIGHT: (C)2005,JPO&NCIPI |
