Currency sorter

A currency sorter comprising

• take-in means for taking currency notes in the sorter one by one;
• discriminating means for discriminating the currency notes according to new and old versions, fit and unfit conditions, denominations and other categories;
• a plurality of stacking units for stacking the currency notes of a predetermined category/categories designated to be bundled according to the discrimination results obtained by said discriminating means, the number of said stacking units being greater by one than the number of denominations;
• bundling means for bundling currency notes of predetermined number;
• designating means for designating the category/categories of the notes to be bundled and a mode of sorting the notes to leave unbundled;
• and
• control means for controlling allocation of currency notes discriminated by said discrimination means to one of said plurality of stacking units according to a designation by said designating means, and for controlling taking-in operation of said take-in means such that after one of the stacking units becomes completely full and the extra stacking unit is substituted to stack the notes of the same denomination, if the remaining stacking units are about to be full, said take-in means is switched from “continual feeding” to “intermittent feeding” to confirm denomination by said discriminating means and the substitution continues until new space generates in the extra stacking unit.
