Even when the rear end of the banknote P has passed the optical axes of the optical sensors 4 and 3, the rear end skew θ2 of the banknote P is calculated in the same manner as above. Then, the time from the front end of the bill P reaching the rear end to each optical axis of the optical sensors 4 and 3 is measured, and from the measured time and the known conveyance speed V of the bill P, FIG.
The dimension (a) (length of the banknote P on the optical sensor 4 side in the carrying direction) X1 and the dimension (figure 7 (b) (length of the banknote P on the optical sensor 3 side in the carrying direction) X2 are calculated. Then, the following three conditions are determined. Note that FIG. 7A shows the state on the side of the optical sensor 4, and FIG. 7B shows the state on the side of the optical sensor 3.

Condition 1. Does the dimension X1 match L / COS (θ1)? Condition 2. Does the dimension X2 match L / COS (θ2)? Condition 3. Do θ1 and θ2 match? A banknote P that satisfies the above three conditions is determined to have a normal shape, and a banknote P that does not satisfy even one of the conditions is determined to have an abnormal shape. It should be noted that, with respect to the banknote P having a regular shape, any one of the above-mentioned three conditions is dependent on the other two conditions, and therefore the judgment may be performed using only any two of them.

Next, the banknote P determined to have the normal shape is subjected to skew control by the processing operation described below. That is, the bill P that has passed through the optical sensors 3 and 4
Is sandwiched and conveyed by the conveyor belts 1a, 1b, 2a and 2b which are driven at a constant speed at a speed equivalent to that of the former stage conveyor. In this case, it goes without saying that each of the conveyor belts 1a, 1b, 2
The rotation speeds of the pulse motors 7a and 7b for driving a and 2b are the same.

At this stage, the controller 41 controls the optical sensors 3,
Based on the skew angle measured based on the output signal of 4,
The conveyance speeds of the left conveyance belts 1a and 2a with respect to the conveyance direction in which the banknote P is delayed are made constant, and the conveyance speeds of the conveyance belts 1b and 2b on the right side with respect to the conveyance direction in which the banknote P is advanced are reduced. Thus, the speeds of the pulse motors 7a and 7b that drive the conveyor belts 1b and 2b are controlled.

As a result, the conveyance speed of the bill P is higher than that of the left conveyor belts 1a and 2a.
The skew of the banknote P is corrected by rotating the banknote P by the amount that b is delayed.

That is, it is determined how much the right side drive roller 6b with respect to the conveying direction should be moved less than the left side drive roller 6a with respect to the conveying direction which moves at a constant speed within a certain time. For example, if the skew angle is 10 °,
If the optical axis distance between the optical sensors 3 and 4 is 80 mm, the correction in the CW direction is necessary, and it is necessary to move the right drive roller 6b less by “80 × tan (10 °) = 14.1 mm” within a unit time. Occurs.

These calculations are performed by the control unit 41, and as a result, the conveying belts 1b, 2b on the advancing side are obtained.
The rotation speed of the pulse motor 7b that drives the motor is reduced. For example, by controlling the speed of the drive roller 6b on the right side so that the belts 1b, 2b on the right side move 36 mm while the belts 1a, 2a on the left side move 50 mm, the skew of the banknote P is corrected so that there is no skew.

Thus, after the skew control is completed, the left and right conveyor belts 1a, 1b, 2a, 2b are returned to the normal conveyor speed and driven, so that the left and right conveyor belts have normal conveyor speeds, and the conveyor path 23 in the subsequent stage is returned. It becomes possible to deliver the banknote P to.

Since the pulse motors 7a and 7b perform such processing in a short time of, for example, about 40 ms, it is necessary to perform very rapid acceleration / deceleration. When correcting the skew of the banknote P as shown in FIG. 6 described above, the belts 1b and 2b on the right side are driven at a constant speed with respect to the traveling direction that is proceeding, and the conveying speed on the left side with respect to the conveying direction that is delayed. It is possible to correct the skew by increasing the.

However, in the general rotation speed-torque characteristic of the pulse motor, the torque tends to decrease as the rotation speed of the pulse motor increases. Therefore, skew correction by increasing the rotation speed of the pulse motor is
The required torque cannot be obtained from the torque characteristics of the pulse motor, which is not appropriate. To secure the required torque, a very large pulse motor is required.

Actually, in the banknote handling apparatus, for example, the length of the banknote P is 76 mm, but the interval between the banknotes P to be conveyed is usually about 80 mm, and in the skew control transfer apparatus 22 of this embodiment. Since the skew is controlled during the conveyance length of about 50 mm, the processing time can be sufficiently made.
