PROBLEM TO BE SOLVED: To provide a technology for highly accurately conveying a sheet to a predetermined position.SOLUTION: A printer device executes paper feeding control processing for abutting a sheet on the sheet taking-in position of a conveyance roller from a paper feeding roller by rotating the paper feeding roller positioned on an upstream side forward in the reverse-rotated state of the conveyance roller positioned on the downstream side. Then, the printer device executes paper setting control processing for further taking in the paper to the downstream side by rotating the conveyance roller forward and conveying the sheet to an image forming position. However, during the change from the paper feeding control processing to the paper setting control processing, the sheet naturally rotates. Thus, in the paper setting control processing, the rotational amount δ of the conveyance roller during the change from the paper feeding control processing to the paper setting control processing is first calculated (S430). Then, the target rotational amount of the conveyance roller is corrected by the rotational amount δ (S440). Thus, the sheet is highly accurately conveyed to a predetermined position by suppressing the effect of the rotational amount δ. |
