[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet transporting device for sending out a sheet or the like, and more particularly to a sheet transporting device in which the assembly of the device is simple and the transport operation is smooth.

[0002]

2. Description of the Related Art For example, when a deposited paper money is stored in a ticketing machine or when a bill of a fishing tag is issued, it is difficult to use such a method.
A bill processing device for taking out bills from a stacker containing bills is provided.

[0003] Some of such banknote handling machines incorporate a low friction outer peripheral surface and a paper feed roller having a high friction outer peripheral surface formed at a predetermined position on the outer peripheral surface. The outer periphery of the sheet delivery roller is, for example,
The stacker rotates while abutting on the surface of the lowermost banknote.

In such a banknote handling machine, a banknote is fed out only when the surface of the lowermost banknote of the stacker is in contact with the high friction surface of the rotating paper feed roller, and the banknote of the lowermost banknote of the stacker is fed. When the front surface is in contact with the low friction surface of the paper feed roller, the paper money is not fed. Thus, the banknotes stored in the stacker can be intermittently taken out.

[0005] As a sheet transporting device used in such a banknote handling device, there is, for example, one shown in FIG. The sheet conveying device shown in FIG.
Roller 11 having a high friction outer peripheral surface 112 formed on a roller 11a

And the high friction outer peripheral surface 112, for example,
In order to take out banknotes stably and intermittently,
It is necessary to accurately align the positions of the high friction outer peripheral surfaces 112 of the two rollers 110, and a complicated positioning operation occurs, which is a problem.

[0008] Timing belt 1 hanging on pulley 113
The roller 1 that was removed after the belt was replaced
When restoring the roller 10, it is necessary to accurately match the high-friction outer peripheral surface 112 of the removed roller 110 with the high-friction outer peripheral surface 112 of the existing roller 110. . In addition, even when adjusting a small deviation, it is necessary to loosen the push screw 115 of the roller 110, and the adjustment is troublesome.

There is also a problem that the number of parts is large and the price cannot be reduced. Further, since the roller 110 and the toothed pulley 113 are separate bodies and do not have an integral connection with each other, the smoothness of the operation is sometimes lacked.
