ABSTRACT:
In a printer for passbooks or the like, a passbook or the like, which is brought in on a transfer path, is stopped at the position of a page-turning roller, where a sheet is turned over by the operation of the page-turning roller. When a sheet is turned over by the page-turning roller, at a position separate from a start position of turning over of a sheet, a passbook or the like undergoes an initial deformation in a out-of-plane direction so that the passbook is bent in a first-order mode. By this initial deformation, a sheet can be turned over steadily. Such a turnover of the sheet can be effected in conjunction with utilizing an optical system which provides an image of the three-dimensional deformation pattern of the passbook which is processed. In accordance with this pattern a decision is made whether or not the out-of-plane deformation of the passbook is more than a specified amount. In the vicinity of the transfer path, a page-turning roller is provided and is supported rotatably. In the vicinity of the transfer path there is also provided a push guide which gives a deformation to the passbook when a sheet is turned over. Based on a frictional control of the page-turning operation, a steady turnover of the sheet can be effected regardless of buckling resistance force of the sheet to be turned over.
