Abstract: Paper currency is conveyed to a resend area 522 when deposited paper currency is folded paper currency, wherein a front corner thereof, relative to the direction of conveyance, is folded, based on information that is read in from a sensor unit 530a. In the resend area 522, the folded location is up. The folded paper currency is resent within the resend area 522. The action of the conveying rollers 551 and 552 corrects the fold of the paper currency within the resend area 522.

Abstract: A paper currency handling apparatus capable of determining destination of each paper currency based on currency identification result before conveyance into a temporal storage if the order of paper currencies entered by user varies within the temporal storage. The apparatus has a conveyance path conveying paper currencies, an identification portion identifying each paper currency conveyed, a storage portion storing identification information indicating identification result of each paper currency identified by the identification portion, and a control portion controlling various portions. The identification portion reads unique information about each paper currency conveyed along the conveyance path. The storage portion stores the unique information about the currency read by the identification portion and the identification information about the currency identified by the identification portion by associating these information with each other.

Abstract: A banknote handling apparatus and an automatic teller machine are provided which by no means suffer from the prolonged transaction time resulting from the second discrimination process that must be performed at reduced banknote transfer speeds.

Abstract: An object of the present invention is to trace a user who has deposited bills as counterfeit bank notes into an ATM. The ATM having a bill deposit function judges a denomination and genuineness of bills deposited by the user by a validator, extracts bill information and stores in a search DB its bill information to be matched with an account number of the user (first data). It stores, in a trace DB, bill information of bills judged as counterfeit bank notes by the validator (second data). The search DB is searched with the second data as a key to extract similar bill data for specifying, from a result, the user who has used the bills as counterfeit bank notes.
