Abstract

A paper sheet transport apparatus ( 10 ) includes transport member that is slidable along the widthwise direction of a transport path ( 11 ) (e.g., a drive roller ( 36 ) and a driven roller ( 38 )), and a paper sheet detection unit (inlet-side paper sheet detection sensor ( 70 )) that is arranged on an upstream side of the transport member in the paper sheet transport direction along the transport path ( 11 ) and detects the position of the paper sheet in the widthwise direction of the transport path ( 11 ). A control unit ( 80 ) calculates an amount of movement of the transport member based on the position of the paper sheet in the widthwise direction of the transport path ( 11 ) detected by the paper sheet detection unit and a previously set predetermined position of the paper sheet in the widthwise direction of the transport path ( 11 ).

First claim

The invention claimed is:

1. A paper sheet transport apparatus that transports a paper sheet along a transport path, comprising:
a transport member that is slidable along a widthwise direction of the transport path and transports the paper sheet along the transport path;
a paper sheet detection unit that is arranged on an upstream side of the transport member in a paper sheet transport direction along the transport path and detects a position of the paper sheet in the widthwise direction of the transport path;
a control unit that calculates an amount of movement of the transport member based on a position of the paper sheet in the widthwise direction of the transport path detected by the paper sheet detection unit and a previously set predetermined position of the paper sheet in the widthwise direction of the transport path, and performs a control so as to slide the transport member by the calculated movement amount when the paper sheet is transported by the transport member; and
a first fixed transport member and a second fixed transport member arranged on an upstream side and on a downstream side of the transport member in the paper sheet transport direction, the first fixed transport member and the second fixed transport member being firmly fixed and transporting the paper sheet along the transport path, wherein
the paper sheet detection unit also detects a skew amount of the paper sheet, and
the control unit performs a control so as to slide the transport member along the widthwise direction of the transport path so as to correct a skew state of the paper sheet based on the skew amount of the paper sheet detected by the paper sheet detection unit when the paper sheet is transported from the first fixed transport member to the transport member or when the paper sheet is transported from the transport member and received by the second fixed transport member.

2. The paper sheet transport apparatus according to claim 1 , wherein the transport member includes a pair of upper and lower rollers that transport the paper sheet by nipping the paper sheet therebetween.

3. The paper sheet transport apparatus according to claim 1 , further comprising a position detection unit that detects a position of the transport member in the widthwise direction of the transport path.

4. The paper sheet transport apparatus according to claim 1 , wherein
the transport member is arranged in a first guide portion comprising the transport path, and
the first guide portion is slidable along the widthwise direction of the transport path integrally with the transport member.

5. The paper sheet transport apparatus according to claim 1 , wherein
the transport member is arranged in a second guide portion comprising the transport path,
the second guide portion is firmly fixed, and
the transport member is slidable along the widthwise direction of the transport path with respect to the second guide portion.

6. The paper sheet transport apparatus according to claim 1 , wherein
the transport member comprises a plurality of the transport members arranged in tandem along the paper sheet transport direction,
in the transport path, the paper sheet is transported sequentially starting from the transport member arranged on a most upstream side toward the transport members arranged on a downstream side thereof, and
the control unit controls the transport members to slide along the widthwise direction of the transport path so that a sum total of amounts of movement of the paper sheet in the widthwise direction of the transport path performed by the transport members is equal to the calculated movement amount when the paper sheet is transported sequentially by the transport members.

7. A paper sheet transport apparatus that transports a paper sheet along a transport path, comprising:
a transport member that is slidable along a widthwise direction of the transport path and transports the paper sheet along the transport path;
a paper sheet detection unit that is arranged on an upstream side of the transport member in a paper sheet transport direction along the transport path and detects a position of the paper sheet in the widthwise direction of the transport path; and
a control unit that calculates an amount of movement of the transport member based on a position of the paper sheet in the widthwise direction of the transport path detected by the paper sheet detection unit and a previously set predetermined position of the paper sheet in the widthwise direction of the transport path, and performs a control so as to slide the transport member by the calculated movement amount when the paper sheet is transported by the transport member, wherein
the transport member comprises a plurality of the transport members arranged in tandem along the paper sheet transport direction,
in the transport path, the paper sheet is transported sequentially starting from the transport member arranged on a most upstream side toward the transport members arranged on a downstream side thereof,
the paper sheet detection unit also detects the skew amount of the paper sheet, and
when the paper sheet is transported from one transport member to another transport member arranged at a stage subsequent to the one transport member, the control unit controls at least one of the one transport member and the another transport member to slide along the widthwise direction of the transport path so as to correct the skewed state of the paper sheet based on the skew amount of the paper sheet detected by the paper sheet detection unit.

8. The paper sheet transport apparatus according to claim 1 , wherein
in the transport member, a plurality of pairs of upper and lower rollers that transport the paper sheet by nipping the paper sheet therebetween are arranged in tandem along the widthwise direction of the transport path, and
the control unit adjusts a rotation speed of each of the plurality of pairs of rollers arranged in the transport member so as to correct the skewed state of the paper sheet based on the skew amount of the paper sheet detected by the paper sheet detection unit when the paper sheet is transported by the transport member.

9. The paper sheet transport apparatus according to claim 7 , wherein the transport member includes a pair of upper and lower rollers that transport the paper sheet by nipping the paper sheet therebetween.

10. The paper sheet transport apparatus according to claim 7 , further comprising a position detection unit that detects a position of the transport member in the widthwise direction of the transport path.

11. The paper sheet transport apparatus according to claim 7 , wherein
the transport member is arranged in a first guide portion comprising the transport path, and
the first guide portion is slidable along the widthwise direction of the transport path integrally with the transport member.

12. The paper sheet transport apparatus according to claim 7 , wherein
the transport member is arranged in a second guide portion comprising the transport path,
the second guide portion is firmly fixed, and
the transport member is slidable along the widthwise direction of the transport path with respect to the second guide portion.

13. The paper sheet transport apparatus according to claim 7 , wherein
the transport member comprises a plurality of the transport members arranged in tandem along the paper sheet transport direction,
in the transport path, the paper sheet is transported sequentially starting from the transport member arranged on a most upstream side toward the transport members arranged on a downstream side thereof, and
the control unit controls the transport members to slid
