Moreover, as described in Utility Model Application Publication No. 58-124873,
A cylindrical roller having a heat generating element and a pressure roller are opposed to each other, and the bill is passed through the gap to correct creasing. In this structure, it is necessary to extend the crease in the direction perpendicular to the conveying direction before the cylindrical roller having the heating element. This is because, when a banknote is conveyed between a pair of pressure rollers, it may have a distinct tendency to bend. However, the mechanism for correcting this bending tendency is to install two plates facing each other and move them to both sides using screws.

[Problem that the invention seeks to solve, α]

Although the above-mentioned conventional technology takes into account the ability to temporarily correct folds and bends in paper strips to improve conveyance reliability, once one piece of paper is freed, it returns to its original state, which is difficult to do on complicated conveyance routes. There was a problem that guidance was required.

Also, in a mechanism using a roller with one heating element.

No consideration has been given to correcting folds in banknotes transported at high speeds, so when banknotes are transported at high speeds, folds in the direction perpendicular to the transport direction are corrected using a cylindrical roller with a heat generating element. The sheet is conveyed between the pressure rollers, and the folds are rather clearly formed between the rollers, so that a fold correction mechanism having such a structure cannot be applied to a paper sheet processing apparatus.

The purpose of the present invention is to correct the folds and bends of paper pieces so that they do not recover, improve the reliability of conveyance in a paper sheet processing device, simplify the configuration of the conveyance path, and realize cost reduction. It is in.

[Means for solving problems]

The above purpose is to use a heating roller section that has a heating element that is divided into a plurality of parts in the direction of the rotation axis, and a plurality of pressurizers that are pressed against the heating element of this heating roller section. This is achieved by constructing a fold straightening device using a pressing roller section having rollers, and passing the paper between the roller sections of the fold straightening device.

[Effect]

Paper sheets are conveyed while being held in pressure contact between a heating roller section having a heating element divided into a plurality of parts and a pressing roller section having a plurality of pressing rollers that are pressed against and in contact with these heating elements with appropriate pressure. When the paper sheets are folded, their creases are corrected by a heating element and a pressure roller.
