The plurality of bearings 200 are arranged to have a center of rotation on the same straight line. At this time, each bearing 200 may be coupled to the same rotation axis (not shown), each bearing 200 may be fastened to a separate frame.

The conveying roller 100 is formed such that the rotating shaft hole 130 through which the rotating shaft 150 is fastened in a cylindrical shape penetrates both end surfaces of the circular shape. And the outer peripheral surface 102 of the conveying roller 100 is arranged to abut the bearing 200.

In this case, the outer circumferential surface 102 includes a first contact portion 110 made of metal and a second contact portion 120 made of rubber or resin.

The first contact portion 110 is a region made of a metal material having high strength, and prevents the shape of the conveyance roller 100 from being deformed by the banknote 4 even when the banknote 4 passes.

The second contact portion 120 is for preventing the banknote 4 from slipping while the banknote 4 is inserted, and is formed using a material having a frictional force higher than that of the first contact portion 110 made of metal. can do. For example, the second contact portion 120 may be formed using a resin such as urethane.

The second contact portion 120 may be formed in a circular band shape having a width length smaller than the width of the outer circumferential surface 102.

Since the conveyance roller 100 is made of the first and second contact portions 120 having the outer circumferential surface 102 in contact with the banknote 4 having different strengths and friction forces, the banknote can be prevented from slipping while the banknote passes. The operation of detecting the thickness of can be faithfully performed.

That is, since the first contact portion 110 is formed of a metal material, the change of form does not occur even when the banknote passes, and the thickness of the banknote can be precisely measured. In addition, the second contact portion 120 may be formed using a resin-based material, thereby preventing the banknote from slipping at the moment when the banknote is inserted.

The conveying roller 100 including the second contact portion 120 can be manufactured by embedding the resin in a cylindrical roller having a groove formed on the outer circumferential surface thereof. The manufacturing method of the conveying roller 100 is briefly described as follows.

In addition, Figure 6 shows a conveying roller 700 according to another embodiment, the second contact portion 720 may be formed to have a plurality of circular band form interposed between the first contact portion 710.

The second contact portions 120, 620, and 720 of the conveying rollers according to the above embodiments have been shown to have a strip shape surrounding the outer circumferential surface.

Unlike this, as shown in FIG. 7, the second contact portion 820 of the conveying roller 800 may be formed to have a specific pattern at a portion of the outer circumferential surface. For example, the second contact portion 820 may have a rectangular orthographic shape projected onto a plane facing the outer circumferential surface.

In this case, the second contact portion 820 may be formed in a polygonal or circular shape of another shape.

It is to be understood by those skilled in the art that the present invention may be embodied in many other forms without departing from the spirit and scope of the invention,

That is, the second contact portion of the conveying roller is not limited to the embodiments shown in the drawings, but is partially surface-treated to increase the frictional force on the metallic outer circumferential surface, and the form may be variously implemented.

In addition, the double sheet detecting device including a conveying roller is also for detecting a change in the gap between the bearing and the rollers due to the input of the bill, the shape of the double sheet detecting device and the position of the magnet and the sensor can be variously implemented.

And the above-described embodiments have described the formation of the second contact portion using a material with a large friction force in the conveying roller of the bearing and conveying roller sandwiching both sides of the bill in the process of conveying the bill. It is apparent that the scope of the present invention is not limited to the formation of the second contact portion in the conveying roller, but may be formed in the bearing.
