Claim:
A currency sorter comprising: a take-in unit to take-in currency notes in the sorter one by one; a discrimination unit to discriminate the currency notes according to a plurality of categories selected or combined from currency note conditions including new and old versions, fit and unfit conditions and denominations; a plurality of stacking units to stack the currency notes of a predetermined category/categories designated to be bundled according to the discrimination results obtained by said discrimination unit, the number of said stacking units being greater by one than the number of denominations; a bundling unit to bundle currency notes of predetermined number stacked in said plurality of stacking units; a counter to count the currency notes stacked in said plurality of stacking units; a conveying route to convey the currency notes from said take-in unit to said stacking units; a designating unit to designate the category/categories of the notes to be bundled and a mode of sorting the notes to leave unbundled; and a control unit to control allocation of currency notes discriminated by said discrimination unit to one of said plurality of stacking units according to a designation by said designating unit, and for controlling taking-in operation of said take-in unit, such that after one of the stacking units becomes completely full, the extra stacking unit is substituted to stack the notes of the same denomination, and when stacking in the extra stacking unit, if it is detected that the remaining stacking units are about to be full by the counter, feeding mode of said conveying route is switched from “continual feeding” to “intermittent feeding” to confirm denomination by said discriminating unit and the substitution continues until new space generates in the extra stacking unit.
