FIG. 4 shows the flow of the operation of re-discrimination of rejected bills by the paper sheet handling apparatus according to the present invention incorporated in the cash transaction apparatus. The first embodiment shown in FIG. The operation of the example will be described. The reject banknote means a banknote whose denomination and the number of coins have not been determined by the discrimination units 203 and 207 during the handling of the banknote.

At the time of withdrawal, the bills separated and taken out one by one from the denomination boxes (denoted by reference numerals 204, 205, and 206 in FIG. 1) accommodated in denominations are discriminated by the discrimination section 20.
At 7, the denomination and the number of coins are identified. The bill normally discriminated by the discriminating unit 207 is conveyed to the deposit / withdrawal port 202 and is discharged to the customer. On the other hand, uncertain banknotes whose denomination and number of coins cannot be discriminated are stored in the apparatus inside the banknote state detection unit 211
Thus, the conveyance state of the banknote is detected, and the skew / shift correcting mechanism 209 corrects the skewed posture of the banknote or the shift state in which the banknote is moved in parallel from the normal position based on the detection information. After this, the corrected banknotes will be transferred to the banknote discriminating section 20.
In step 7, the denomination and the number of denominations are discriminated again, and the bill with the fixed amount and denomination is conveyed to the deposit / withdrawal port 202. On the other hand, the banknote state detection unit 211 again detects the conveyance state of the banknote for which the amount and denomination are uncertain. Denomination,
The above operation is repeated until the number of sheets is decided.

In addition, by using such a paper handling device as a banknote transport device in an automated teller machine, it becomes possible to automatically examine bills in the automated teller machine and improve the efficiency of cash management operations of financial institutions. You can

Further, even when it becomes necessary to recount the bills in the apparatus, the total amount of bills can be determined completely automatically without generating unknown bills. Further, this eliminates so-called reject bills, and the storage box dedicated to reject bills can be made smaller or deleted.

FIG. 5 shows another example of the operation of re-discrimination of rejected banknotes which occurs when the banknotes are dispensed by the paper sheet handling apparatus according to the present invention incorporated in the cash transaction apparatus. The operation of the first example of the embodiment shown in FIG. 1 will be described with reference to this figure. At the time of withdrawal, the banknotes are separated one by one from the denomination boxes (shown by reference numerals 204, 205, and 206 in FIG. 1) that are stored according to the denomination, and the extracted banknotes are discriminated by the discriminating unit 207. Differentiate the number of sheets. When an indeterminate banknote whose denomination and the number of coins cannot be discriminated by the discriminating unit 207, separation from the denomination boxes 204, 205, 206 is stopped or delayed. This discriminating section 2 before the occurrence of reject banknotes
The bill normally discriminated in 07 is conveyed to the deposit / withdrawal port 202 and is discharged to the customer.

The rejected bill is detected by the bill state detecting section 211 provided inside the apparatus as to the conveyance state of the bill.
The skew / shift correcting mechanism 20 is based on the detected information.
In 9, the skewed posture of the bill and the shift state in which the bill is translated from the normal position are corrected. After that, the corrected banknotes are again discriminated by the banknote discriminating unit 207 for the denomination and the number of denominations, and the banknotes whose amounts and denominations have been fixed are conveyed to the deposit / withdrawal port 202.

On the other hand, with respect to the banknote whose amount and denomination are uncertain, the banknote state detecting section 211 detects the state of conveyance of the banknote again. The above operation is repeated until the type and number of bills are determined. After that, after the re-identification of the reject bill is completed, the separating operation is restarted and the normal operation is restored.

In the paper sheet number determining device having the above-described structure, when the discriminating unit detects the occurrence of the indeterminate banknote, the separation from the denomination box is stopped, and the indeterminate banknote becomes indeterminate. After correcting the abnormal state of the banknote that is the cause, it is re-conveyed, so the increase in the abnormal state of the conveyed banknotes is suppressed,

The mechanism shown in FIG. 15 clamps a bill and rotates the roller 113 based on the conveyance timing and bill conveyance state information detected by the sensor 211 to correct the skew (FIG. 15 (2)). ), The shift is corrected by rotating the roller 112 (FIG. 15C). Although not shown here, it also has a transport mechanism for transporting banknotes.

FIG. 16 shows how the control amount is determined based on the skew amount and shift amount detected by the bill state detection mechanism in the mechanical operation of FIG. FIG.
6, point B is the point at which the skewed / shifted banknote is conveyed and comes into contact with the spherical surface of the correction mechanism for the first time. Is the midpoint of the front end with respect to the conveyance direction of the length of the bill in the longitudinal direction, point D is the center of gravity of the bill, and line segment AC is the center line of the bill. θ1 is an angle formed by the line segment DC and the conveyance direction, and is a quantity representing a skew angle of a bill. θ2 is an angle formed by the line segment AB and the conveying direction, and is a skew angle first added to a bill by the posture correcting mechanism according to the present invention. θ3 is line segment AB and line segment AD
It is the angle formed by. X is the projection distance of the line segment BD in the direction perpendicular to the transport direction, and is an amount representing the shift amount of the bill.

In order to correct the shift, the central axis of the bill must come to the position of the sphere. Since the contact point between the sphere and the bill aligns with the central axis of the bill as the sphere rotates in the transport direction, the skew amount of the bill is changed. At this time, the skew amount to be changed must be small in order to shorten the processing time and reduce the load.

The first additional skew angle θ2 at this time is
Calculated from θ3-θ1 from triangle ACB, and θ3 is CB
It can be obtained from the length l1 + l2. That is, from the triangle DCE, l1 = (l4 / 2) tan θ1 (Equation 1) From the triangle BFE, l2 = X / cos θ1 (Equation 2) Equations 1 and 2 and θ3 from the triangle ACB are obtained by Equation 3. To be θ3 = arctan ((l1 + l2) / l4) (Equation 3) From this, θ2 is obtained by Equation 4. θ2 = θ3−θ1 (Equation 4) Further, the rolling distance 13 of the sphere is obtained from Equation 5 from the triangle ACB.
