<p>PROBLEM TO BE SOLVED: To provide a multifunction machine 100 capable of maintaining the number of conveyance sheets per unit time even when paper feeding timing is changed.SOLUTION: A multifunction machine 100 includes: a paper-to-paper time measurement means 403 for measuring a paper-to-paper time of a subsequent sheet from a paper feeding starting time of a prescribed sheet to a paper feeding starting time of the subsequent sheet which is conveyed subsequently to the sheet; an acceleration time calculation means 404 for calculating an acceleration time of the subsequent sheet until switching a first paper feeding line speed of the subsequent sheet from the paper feeding starting time of the subsequent sheet during paper feeding into a second paper feeding line speed higher than the first paper feeding line speed on the basis of the measured paper-to-paper time of the subsequent sheet and a paper feeding line speed curve of a most-delayed subsequent sheet when the paper feeding start of the subsequent sheet is most delayed; and a subsequent sheet acceleration means 405 for accelerating the first paper feeding line speed of the subsequent sheet during paper feeding into a second paper feeding line speed at the calculated acceleration time point.</p> |
