[Industrial Field of Application] The present invention relates to a paper sheet conveying mechanism of a paper sheet handling device, and in particular, a method for correcting skew after completely folding paper sheets by pressing the folds and bends at both ends of the paper sheet. The present invention relates to a paper sheet conveyance mechanism that can perform the following functions.

In recent years, automatic deposit and payment machines (Auto
omatic Teller Machine: Hereafter A
Automated transaction devices such as TM) are widely used, and these devices have a built-in banknote handling device for transporting, storing, and dispensing banknotes to be deposited and withdrawn.

In banknote handling devices, skewing tends to occur during the conveyance of banknotes, so a method is used to correct the skewing by accelerating the banknotes and causing them to collide with a front roller. In this case, if the edges of the banknotes are bent or bent, the banknotes may hit the guide plate on the conveyance path or the position at which they collide with the rollers may be shifted, preventing the banknotes from running or preventing the skew from being corrected. Therefore, a mechanism that can smoothly correct the skew is desired.

(Prior Art) Fig. 4 shows an internal side view of a banknote handling device incorporated in a CD, which shows storage boxes 2a and 2b in which banknotes 1a are stored in advance according to denomination, feeding mechanisms 3a and 3b, A skew correcting section 4 corrects the skew of the fed banknotes 1a; 4 a discrimination and counting section 51 which distinguishes and counts the denomination and front and back of the banknotes 1a; and a reversing section 6 which aligns the front and back sides. A jet box 2c for rejecting and storing unidentifiable banknotes; a pool section 71 for temporarily collecting the fed banknotes 1a; and a dispensing port 8 from which the banknotes 1a are dispensed. and a conveyance path 9 for conveying banknotes 1a between these mechanisms.
The conveyance path 9 consists of routes a=e, and feed rollers, gates, and sensors (not shown) are arranged at important points.

With such a configuration, when a payout command is issued due to a withdrawal request, the payout mechanisms 3a and 3b are activated and the storage box 2
The banknote 1a is fed out from a and 2b, and the banknote 1a is roux 1.
- a is conveyed, passes through the skew correction unit 4, and if there is skew, it is corrected, and the denomination is determined by the discrimination and counting unit 5.

The front and back sides are identified and counted, and sent to the routes 1-h and c, and then sent to the pool section 7 via the route d, with the reverse sides aligned. When the banknotes 1a of the requested amount are pooled in the pool unit 7 in the corresponding denomination and number, they are collectively sent to the withdrawal port 8. If there is a double foot or the like when the banknotes are fed out from the storage boxes 2a and 2b, the banknotes will be judged incorrectly and the banknotes 1a will be sent to the reject box 2c via loops b and e.

Below, regarding the skew correction unit 4 that corrects the skew of banknotes 1a,
This will be explained in detail with reference to FIG. As shown in the side view of FIG. 5(a), the feed roller R that conveys the banknote 1a onto the conveyance path

R6 clamps and conveys the banknote 1a at predetermined positions 1 symmetrical in the lateral direction (longitudinal direction) from the center of the banknote 1a, for example, at a distance of approximately 1/4 of the lateral length of the banknote 1a. The impeller 10a also contacts the surface of the banknote 1a at a similar position and accelerates. Further, the skew correction roller lla nip and convey a predetermined range of both ends of the banknote 1a.

With such a configuration, the feed roller R1 and the presser roller R2 sandwich and convey the banknote 1a, and the banknote 1a is accelerated by the impeller Oa and transferred to the feed roller R3 side near the rolling contact point of the low-speed skew correction roller lla. If the banknote 1a collides with the position of 1a and there is no skew, it will be sent out at a low speed.If there is skew, one end of the banknote 1a will collide first and the other end will be sent out as shown in FIG. They are blocked until they collide, and when they both collide, they are sent out. This is how the skew is corrected.

(Problem to be Solved by the Invention) According to the above conventional method, in the skew correction section 4, the banknote 1a is accelerated by the impeller 10a, and the skew correction roller I

[Means to solve the problem] 1 is a diagram showing the principle of the present invention.

In the figure, 1 is a sheet of paper, 17 is made of an elastic resin material, and is conveyed by rotation while holding the sheet 1 within a predetermined distance symmetrically from the center with respect to the feeding direction of the sheet 1+. A pair of feed rollers 18 are made of a material harder than the feed roller 17, and are placed coaxially with the pair of feed rollers 17, respectively, at positions corresponding to a predetermined range including both ends of the paper sheet 1. A plurality of pairs of pressure rollers are provided facing each other with a gap in thickness between them, and rotate together with the feed roller 17 so that a predetermined range of the paper sheet 1 passes. , an impeller that accelerates and conveys the paper sheets conveyed by the feed roller I7 and the pressure roller 18δ; 11 is the impeller 1;
A pair of diagonal conveyors are provided at the latter stage of 0, rotate at a speed lower than the speed of the paper sheet 7 accelerated by the impeller 10, and are opposed and rotated in contact with each other to sandwich and convey the paper sheet 1 at least near both ends. It is a correction roller.

Therefore, the paper sheet 1 accelerated by the impeller 10 is configured to collide with the skew correction roller 11 to correct the skew of the paper sheet 1 and convey it.

[Effect]

The paper sheet 1 conveyed by the feed roller 17 and the press roller 18 is pressed at a predetermined range on both ends by the press roller 18, and if there is any bending or bending, it is completely folded and no rising portion is left. Therefore, when it is accelerated by the impeller 10 and collides with the low-speed skew correction roller 11, the completely folded end collides, and the skew correction is performed in the same way as the sheet 1 that is not bent or folded. Therefore, it is possible to prevent the occurrence of jars due to bending or bending.
