Abstract: There is provided a base machine including a base machine feed path that conveys a paper sheet, and a validator identifying the paper sheet conveyed by the base machine feed path; an expansion unit including an extension feed path extending from the base machine feed path, a branching feed path branching from the extension feed path, and a plurality of stacking portions that are connected to the branching feed path and stack the paper sheet identified by the validator; and a control portion that, when a conveyance abnormality occur, continues conveyance operation of at least one of the extension feed path and the branching feed path without immediately stopping the conveyance operation and conveys the paper sheet to a predetermined stacking portion that is any of the plurality of stacking portions, in accordance with a location where the conveyance abnormality occurred and a type of the conveyance abnormality.

Abstract: A paper sheet detection device includes: an optical sensor that includes a light-emitting portion that emits light, and a light-receiving portion that receives the emitted light; a storage portion that stores a first threshold value used for determining whether or not a paper sheet is present in a path of the emitted light, a target light-receiving level set as a target value of a level of the light received by the light-receiving portion in a state where the paper sheet is not present, and a second threshold value that is set to a value that is greater than the first threshold value and less than the target light-receiving level; an estimating portion that determines whether the level of the light received by the light-receiving portion is equal to or greater than the first threshold value and less than the second threshold value, and that estimates whether or not the paper sheet is present; and a light amount adjusting portion that adjusts an amount of the light emitted by the light-emitting portion so that

Abstract: A currency deposit processor transfers currencies set in a deposit part one by one, discriminates the currencies by denominations, stores the currencies in denominations in a storage part without temporarily holding the currencies, and confirms the deposited currencies for each transaction. A control unit is provided that, when one storage part reaches its maximum capacity with both currencies confirmed up to a previous deposit transaction and currencies unconfirmed in a current deposit transaction and a failure occurs after the filling-up currencies are removed, performs a special control, in which data on the currencies unconfirmed in the current deposit transaction and included in the filling-up currencies is calculated as a partial confirmation, and the data on the currencies calculated as the partial confirmation is added and reflected at a time of another deposit transaction after a fault recovery process.

Abstract: A paper sheet processing device includes: a charging inlet that takes in paper sheets in a conveyance direction, the paper sheets including at least one target sheet and a partition card overlapped on the target sheet, the partition card having a main surface portion having at least one identification hole group, the identification hole group having at least two through holes arranged along the conveyance direction; a detection unit that detects take-in of the paper sheets by the charging unit, and detects the identification hole group; and a control unit that determines a paper sheet is the partition card in a case where the identification hole group has been detected by the detection unit, and determines that a paper sheet is the target sheet in a case where the identification hole group has not been detected by the detection unit.
