A storage unit stores information on a paper sheet read by a bill reader and a verification unit verifies the paper sheet using the information on the paper sheet stored in the storage unit. If the paper sheet is determined to be counterfeit in the verification, a conveyance unit conveys the paper sheet toward the insertion slot. A comparison unit compares the image data of the inserted paper sheet with image data of a previously inserted paper sheet and if the image data of the inserted paper sheet is determined to be identical to the image data of the previously inserted paper sheet in the comparison, a control unit sends a signal to a host apparatus. ## Claims ### Claim 1 A paper sheet processing apparatus comprising: an insertion slot through which a paper sheet is to be inserted; a conveyance unit configured to convey the paper sheet inserted through the insertion slot; a reading unit configured to read information on the paper sheet conveyed by the conveyance unit; a verification unit configured to verify the paper sheet using the information read by the reading unit; a control unit configured to control the conveyance unit to convey the paper sheet toward the insertion slot in a case where the verification unit determines the paper sheet is counterfeit as a result of the verification; a storage unit configured to store information on a paper sheet determined by the verification unit to be counterfeit; and a comparison unit configured to compare the information on the paper sheet inserted through the insertion slot with the information on the paper sheet stored in the storage unit, wherein the control unit is further configured to send a report signal to a host apparatus in a case where the comparison unit determines that the information on the paper sheet inserted through the insertion slot is identical to the information on the paper sheet stored in the storage unit as a result of the comparison. ### Claim 2 (depends on 1) The paper sheet processing apparatus according to claim 1, further comprising a counter configured to count number of times of detection of the same paper sheet in response to determination of the comparison unit that the information on the paper sheet inserted through the insertion slot is identical to the information on the paper sheet stored in the storage unit, wherein the control unit is configured to determine that the inserted paper sheet the information on which is determined to be identical to information on a paper sheet stored in the storage unit is counterfeit, depending on the count value of the counter. ### Claim 3 (depends on 1) The paper sheet processing apparatus according to claim 1, further comprising a timer configured to count a predetermined time, wherein the control unit is configured to determine that the inserted paper sheet the information on which is determined to be identical to the information on the paper sheet stored in the storage unit is counterfeit when the count value of the number of times of detection of the same paper sheet becomes equal to or greater than a predetermined value within the predetermined time counted by the timer. ### Claim 4 (depends on 1) The paper sheet processing apparatus according to claim 1, further comprising a report device configured to report a result of the verification, wherein the control unit is configured to create a report signal different from the report signal to be sent to the host apparatus and make the report device output a result in accordance with the report signal in a case where the comparison unit determines that the information on the paper sheet inserted through the insertion slot is identical to the information on the paper sheet stored in the storage unit. ### Claim 5 (depends on 1) The paper sheet processing apparatus according to claim 1, further comprising: an imaging device configured to take a facial image of a supplier who inserts a paper sheet and acquire image data; and a line sensor configured to scan identification information on a paper sheet inserted in the paper sheet processing apparatus, wherein the storage unit is configured to store the identification information acquired by the line sensor associated with the image data acquired by the imaging device in a case where the comparison unit determines that the information on the paper sheet inserted through the insertion slot is identical to the information on the paper sheet stored in the storage unit.
