PROBLEM TO BE SOLVED: To inhibit a belt from being deviated by a rightward-ascending-direction external force applied to continuous paper, by supporting a driven pulley in the state of tilting it in a rightward-descending direction through the use of a minimum change in type without the structural change of a tractor. SOLUTION: A bearing hole position of a tractor body for supporting one end of the driven pulley and a bearing hole position of a tractor body cover for supporting the other end are arbitrarily selected, and the driven pulley is supported in the state of being tilted in the rightward-descending direction.
