Abstract
Many kinds of paper sheets such as tickets, cards, bills, and checks, are widely used in the modern community. To handle such a variety of sheets, the sheet-stacking mechanism of a sheet-handling apparatus must be able to handle sheets of various sizes, rigidities, and coefficients of friction. Accordingly, we have developed a new sheet-stacking mechanism that can handle various sizes of sheets by means of looped plastic sheet attached to a roller. These looped sheets generate a breaking force that ensures the paper sheets are stopped correctly. To avoid jamming and incorrect stacking, the mechanism is designed so that the breaking force is in a practical range. Calculation and experiment showed that the new mechanism can stack sheets of various sizes successfully without jamming.
