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.

Sheet paper processing device

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 the level of the light received by the light-receiving portion becomes the target light-receiving level in the state where the paper sheet is not present when the estimating portion estimates that the paper sheet is not present after the estimating portion determines that 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.

Paper sheet detection device, paper sheet detection method, and paper sheet processing device

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.
