ついで、姿勢補正制御部９７は、この算出した駆動角度θと上記第１の補正部３２の駆動軸３５の現在の位置とに基づいて、第１の補正部３２のステッピングモータ４８を駆動制御する（ＳＴ４）。この駆動により上記駆動軸３５を補正する角度の位置まで回転する。
【００７１】
この結果、紙幣Ｐ（Ｐｂ）が上記第１の補正部３２を通過する際、ゴムローラ３７ａ、３７ｂ、３８ａ、３８ｂにより位置ずれを補正する移動が行われる。この際、駆動軸３５の判双方向に交差する方向に対する角度とゴムローラ３７ａ、３７ｂ、３８ａ、３８ｂにより紙幣Ｐが搬送される時間とにより、上記補正量ｘ_０が決定されている。
【００７２】
上述したように姿勢補正制御部９７にて当該紙幣Ｐのシフト量ｘ_０、スキュー角度α、および短端辺の長さｌが判断されると、続いて、ｔａｎθ＝ｘ_０／ｌなるθが姿勢補正制御部９７にて算出される。そして、このθの角度だけ、図４に矢印８１として示すように、第１の補正部３２の駆動軸３５を回転させるように、ステッピングモータ４８を回転駆動する。このとき、第１の補正部３２の円筒軸４３と軸４４が逆方向に回転するが、ワンウエイクラッチ５５が空転するために、第１の補正部３２の回転速度は変化しない。
【００７３】
この状態で第１の補正部３２に紙幣Ｐが送り込まれると、当該紙幣Ｐは、ゴムローラ３７ａ、３７ｂ、３８ａ、３８ｂによって挟持拘束されつつ搬送される。ゴムローラ３７ａ、３７ｂ、３８ａ、３８ｂによって搬送される紙幣Ｐは、搬送路７の中心線７ａに対して、θだけシフトした方向Ｔ’に指向される。このとき、当該紙幣Ｐは、そのスキュー角αを維持したまま矢印Ｔ’方向に指向され、幅方向の位置ずれだけが補正される。
【００７４】
次に、第１の補正部３２を通過した当該紙幣Ｐの先端がセンサ８２を通過したタイミング、すなわち当該紙幣Ｐ（Ｐｃ）が第２の補正部３３のゴムローラ３７ａ、３７ｂ、３８ａ、３８ｂで挟持拘束されたタイミングで、第２の補正部３３をαだけ図中矢印８３の方向に回転させる。このように、第２の補正部３３のゴムローラ３７ａ、３７ｂ、３８ａ、３８ｂが当該紙幣Ｐをクランプした状態で、第２の補正部３３が回転することで、当該紙幣Ｐ（Ｐｄ）の傾きが補正される。
【００７５】
以上の一連の制御動作で、シフトとスキューが連続的に補正された紙幣Ｐは、搬送姿勢が補正されてセンタリングされた正しい姿勢の紙幣Ｐとして、下流側の検知部１２へ搬送される。
【００７６】
また、姿勢補正装置１１に送り込まれる紙幣Ｐのうち、スキューやシフトのない紙幣Ｐについては、第１及び第２の補正部３２、３３の回転軸３５、３５を回転させないことで、正しい姿勢を保ったまま直後の検知部１２へ搬送される。尚、本実施の形態において、正しい姿勢とは、紙幣Ｐの長手方向に沿った一端辺が搬送路７の中心線７ａと直交し、且つ紙幣Ｐの中心が中心線７ａ上に位置する基準姿勢を言う。
【００７７】
上記実施形態では、姿勢補正制御部９７にて当該紙幣Ｐのシフト量ｘ_０、スキュー角度α、および短端辺の長さｌが判断されると、シフト量ｘ_０、スキュー角度α、短端辺の長さｌおよびゴムローラ３７ａ、３７ｂの間隔Ｄをパラメータとして、ｔａｎθ＝ｘ_０／ｌなるθが姿勢補正制御部９７にて算出される場合について説明したが、これに限らず、シフト量ｘ_０、スキュー角度α、短端辺の長さｌに対するｔａｎθ＝ｘ_０／ｌなる駆動角度θをメモリにテーブル化して持つことにより、姿勢補正制御部９７にて算出することなく、処理できるようにしても良い。
【００７８】
この場合、メモリ９１は、動作プログラムを記憶したり、データ記憶用に用いられるものであり、上記紙幣Ｐの搬送方向の傾き量と所定位置からの位置ずれ量と、紙幣Ｐの搬送方向の長さと、上記２つのゴムローラ（位置補正ローラ）３７ａ、３７ｂの間隔とをパラメータとして、上記支持アームとしての駆動軸３５の駆動角度をあらかじめ記憶する記憶手段としての駆動角度テーブル９１ａが設けられている。
【００７９】
姿勢補正制御部９７は、紙幣Ｐの搬送位置ずれ量、スキュー量、紙幣Ｐの搬送方向の長さに基づいて、紙幣Ｐの搬送位置ずれ量、スキュー量、紙幣Ｐの搬送方向の長さと上記第１の補正部３２のゴムローラ３７ａ、３７ｂの間隔をパラメータとした上記第１の補正部３２の駆動軸３５の駆動角度をメモリ９１の駆動角度テーブル９１ａから読出し、この読出した駆動角度と上記第１の補正部３２の駆動軸３５の現在の位置とに基づいて、上記駆動軸３５を回転制御するものである。
【００８０】
次に、上記のように構成された姿勢補正装置１１の第１の補正部３２による補正動作について、図９に示すフローチャートを参照して説明する。
【００８１】
すなわち、搬送路７により第１の補正部３２に搬送される紙幣Ｐに図７に実線で示す程度のスキューαおよびシフトｘ_０を生じているものとする。
【００８２】
この状態において、搬送路７上の図示しないセンサの検知信号により、制御部９０が紙幣Ｐの第１の補正部３２への送り込みを判断した際、制御信号を姿勢補正制御部９７に出力する。これにより、姿勢補正制御部９７は、第１の補正部３２のステッピングモータ５４を駆動制御する（ＳＴ１１）。この駆動により第１の補正部３２のゴムローラ３７ａ、３７ｂ、３８ａ、３８ｂが搬送ベルト対４９ａ〜４９ｃの周速と等しい周速で搬送方向に回転される。
【００８３】
また、上記紙幣Ｐが姿勢検出センサ７０を通過することにより、姿勢検出センサ７０からの検出信号が姿勢補正制御部９７に出力される。
【００８４】
姿勢補正制御部９７は、姿勢検出センサ７０からの検出信号により、図７に示すように、搬送路７を介して姿勢補正装置１１へ送り込まれる紙幣Ｐの搬送状態としてのスキュー量（紙幣Ｐの搬送方向の傾き量、スキュー角度α［°］）αと搬送路７の中心位置（所定位置）７ａからの位置ずれ量ｘ_０［ｍｍ］と紙幣Ｐの搬送方向の長さ（紙幣Ｐの短端辺の長さ［ｍｍ］）ｌを判断する（ＳＴ１２）。
【００８５】
姿勢補正制御部９７は、上記判断した紙幣Ｐの搬送位置ずれ量、スキュー量、紙幣Ｐの搬送方向の長さに基づいて、上記第１の補正部３２の駆動軸３５の駆動角度をメモリ９１の駆動角度テーブル９１ａから読出す（ＳＴ１３）。
【００８６】
ついで、姿勢補正制御部９７は、この読出した駆動角度と上記第１の補正部３２の駆動軸３５の現在の位置とに基づいて、第１の補正部３２のステッピングモータ４８を駆動制御する（ＳＴ１４）。この駆動により上記駆動軸３５を補正する角度の位置まで回転する。
【００８７】
この結果、紙幣Ｐが上記第１の補正部３２を通過する際、ゴムローラ３７ａ、３７ｂ、３８ａ、３８ｂにより位置ずれ上記第１の補正部３２のを補正する移動が行われる。この際、駆動軸３５の搬送方向に交差する方向に対する角度とゴムローラ３７ａ、３７ｂ、３８ａ、３８ｂにより紙幣Ｐが搬送される時間とにより、上記補正量ｘ_０が決定されている。
【００８８】
次に、上記第１の補正部３２の駆動角度θの算出方法について説明する。
１．各種変数の定義
図７は紙幣Ｐが上記第１の補正部３２の左側のゴムローラ３８ａに接触した瞬間を示している。図７において横軸をｘ、縦軸をｙとし、ｙ軸正方向を搬送方向とし矢印で示す。また、シフト補正対象の紙幣Ｐの４辺をＡＢＣＤとし、紙幣Ｐの前辺部ＡＢの中点Ｍのｘ座標を紙幣Ｐのシフト量、辺ＡＢがｘ軸となす角度を紙幣Ｐのスキュー量αと定義する。

BACKGROUND OF THE INVENTION
The present invention relates to a paper sheet processing apparatus that detects and processes features from paper sheets taken out on a transport path, and in particular, takes out and transports a plurality of banknotes one by one on a transport path, The present invention relates to a deposit processing machine that detects features such as orientation and aligns the front and back sides and the top and bottom and accumulates them in denominations.
[0002]
[Prior art]
Conventionally, as a paper sheet processing apparatus, for example, a plurality of banknotes of a plurality of denominations are mixed and put together, the inserted banknotes are picked up one by one on a conveyance path, their characteristics are detected, and their front and back and top and bottom are aligned. There are known deposit processing machines that accumulate by type.
[0003]
[Problems to be solved by the invention]
However, since the size of the banknote varies depending on the denomination and the position of the characteristic part of the banknote varies depending on the denomination, depending on the arrangement position of the detection part for detecting the characteristic, the characteristic part is not opposed to the characteristic part. A denomination that cannot be detected with high accuracy occurs. For this reason, in the conventional apparatus, many detection parts are arrange | positioned in the width direction of a conveyance path, and it has enabled it to detect the characteristic of a banknote now with high precision, even if the characteristic part passes any position. Therefore, since it is necessary to provide such a large number of detection units, there is a problem that the apparatus configuration becomes complicated and the manufacturing cost of the apparatus increases.
[0004]
Further, in the conventional apparatus, when the banknote transport posture is a posture (skew) inclined with respect to the transport path and / or a posture (shift) offset in the width direction of the transport path, the posture failure is thus caused. The bill as it is is conveyed through the conveyance path, and there is a problem that the feature detection accuracy of the bill in the detection unit further decreases.
[0005]
Therefore, there has been proposed one that corrects the misalignment of banknotes with a correction roller before correcting the skew. For example, it is proposed in Japanese Patent Application No. 2000-280843.
[0006]
That is, a Swing Arm Roller (hereinafter abbreviated as SAR) method has been proposed as a method for correcting a shift of a bill that is shifted by a certain distance from the transport center in the transport device. In the SAR method, the rotation axis of the SAR is set perpendicular to the conveyance plane at the conveyance center of the apparatus. At the time of shift correction, this SAR is held at an angle around the rotation axis, and the shift is corrected while the bill passes through the SAR. For this reason, it has been proposed to set the angle of the SAR relative to the transport direction so that the banknote shift amount becomes 0 at the moment when the banknote passes through the SAR and no longer receives any force from the SAR.
[0007]
However, since this proposal can only perform rough correction, there is a demand for one that can correct the misalignment of banknotes with higher accuracy.
[0008]
The present invention has been made in view of the above points, and an object thereof is to provide a paper sheet processing apparatus capable of correcting a positional deviation of paper sheets with high accuracy.
[0009]
[Means for Solving the Problems]
The paper sheet processing apparatus according to the present invention includes a transport unit that transports a paper sheet along a transport path, and a direction that is provided on the transport unit and intersects a transport direction of the paper sheet that is transported by the transport unit. Detecting means for detecting the amount of misalignment and the length of the paper sheet in the transport direction, a support arm provided at the rear stage of the detection means on the transport means and pivotally supported in the center of the transport path, A moving unit that has at least two position correction rollers provided on the support arm at a predetermined interval, and that moves the sheet conveyed by the conveying unit in a direction intersecting the conveying path; and the detection The driving angle of the support arm is calculated using the positional deviation amount of the paper sheet detected by the means from the predetermined position, the length of the paper sheet in the conveyance direction, and the interval between the two position correction rollers as parameters. Calculation means and this Based on the driving angle calculated by the ejecting means, the paper transported by the transporting means is moved by the moving means in the direction intersecting the transporting path while the support arm of the moving means is rotated. Thus, the paper sheet is constituted by a correcting means for correcting a positional deviation from a predetermined position of the paper sheet.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0011]
FIG. 1 schematically shows an internal structure of a deposit processing machine (paper sheet processing apparatus) 1 according to an embodiment of the present invention. The deposit processing machine 1 is used for mixing a plurality of banknotes having different denomination sizes in a lump, putting all the banknotes in front and back, and classifying and collecting the banknotes according to their denominations. Only a bill of a specific denomination has a function of sealing with a paper band every predetermined number.
[0012]
The deposit processing machine 1 has a housing 2 that forms an outer shell of the apparatus. A step portion on the right side of the housing 2 in the drawing is provided with a loading portion 3 for loading a plurality of banknotes P in a standing state in a state where the bills P are stacked in the surface direction. The banknotes P are inserted through the input unit 3 in such a manner that the banknotes P have front and back sides and have an upper end and a lower end extending along the longitudinal direction, and the upper end or the lower end faces downward. The insertion unit 3 includes a stage 3a that aligns all banknotes P in contact with the upper end or lower end thereof. At the right end of the input unit 3 in the figure, a backup plate 4 is provided that is erected in the vertical direction with respect to the stage 3a. The backup plate 4 is provided so as to be movable in the left direction in the drawing along the stage 3a by the urging force of the spring 5.
[0013]
The plurality of banknotes P placed in the insertion portion 3 in a standing position are urged in the surface direction by the backup plate 4 and moved leftward in the figure. Then, the bill P at the left end in the figure is pressed against two sets of take-out rollers 6 (take-out sections) arranged in the state of being adjacent to each other on the left side of the input section 3 in the figure. By rotating the take-out roller 6 in a predetermined direction, the banknotes P placed at the left end among the plurality of banknotes P placed in the standing position 3 are sequentially taken out onto the transport path 7. The banknote P taken out on the transport path 7 is taken out in the short direction with its upper end or lower end as the head. At this time, the front and back of each banknote are in a disjoint state. In this Embodiment, the taking-out direction of the banknote P taken out from the insertion part 3 is downward.
[0014]
The conveyance path 7 is defined by conveyance belts 8 and 9 stretched so as to be capable of endless travel along the conveyance direction above and below the conveyance path 7. Each of the conveyor belts 8 and 9 is wound around a plurality of rollers 10 extending in the width direction (paper surface direction). The transport path 7 is provided with a posture correction device (described in detail later) 11 that automatically corrects the shift and skew of the banknote P that has been taken out.
[0015]
At the tip of the conveyance path 7 bent upward by these conveyance belts 8 and 9, a detector 12 for detecting characteristics such as the denomination, front and back, top and bottom of the banknote P, the presence or absence of dirt and damage, etc. is disposed. Yes. The detection part 12 reads various information from the surface of the banknote P conveyed by the conveyance path 7, compares the read information with the information used as a reference | standard, and detects the characteristic of the banknote P as mentioned above. .
[0016]
By the way, since the banknote P thrown into the insertion part 3 is thrown into the front and back and the top and bottom apart, when it is taken out (taken in) on the conveyance path 7, the orientation of the front and back and top and bottom is separated. It has become. For this reason, the banknotes P of multiple denominations passing through the detection unit 12 are in a state where the front and back sides and the top and bottom are scattered.
[0017]
A plurality of gates G <b> 1 to G <b> 9 for selectively switching the conveyance direction of the banknote P based on the detection result in the detection unit 12 are provided on the conveyance path 7 extending downstream of the detection unit 12. .
[0018]
Bills such as banknotes that have been determined to be picked by the detection unit 12, banknotes that have been determined to have greatly skewed beyond a predetermined level, or banknotes that are not determined to be redistributable bills, counterfeits, etc. A banknote determined to be incapable of subsequent processing, such as (not necessarily a banknote), is conveyed to the right in the figure via the gate G1 and discharged to the reject box 13. The reject box 13 can be accessed from outside the housing 2 of the deposit processing machine 1.
[0019]
On the other hand, the banknote P determined to be a normal banknote that can be processed by the detection unit 12 is conveyed in the left direction in the drawing toward the gate G2 via the gate G1. As described above, the banknote P passed through the gate G1 is in a state where the front and back sides and the top and bottom are separated. In this way, the banknotes P in which the front and back sides and the top and bottom are separated pass through the front and back reversing mechanism 14 which will be described later, so that the front and back sides are collected, and are classified and accumulated for each denomination. In the present embodiment, all banknotes P are basically stacked with the front facing up.
[0020]
The conveyance path on the downstream side of the gate G2 is branched in two directions, and the conveyance direction of the bills P is selectively switched in two directions by selectively switching the gate G2 between two positions.
[0021]
On one conveyance path branched on the downstream side of the gate G2, a front / back reversing mechanism 14 (front / back reversing part) for reversing the front and back of the banknote P is provided. The conveyance path passing through the front / back reversing mechanism 14 forms a torsion conveyance path rotated by 180 ° around the central axis from the inlet toward the outlet. Then, two pairs of the conveyor belts 15 and 15 are provided in a twisted state so as to meet each other along the torsion conveyance path. Moreover, the other conveyance path branched on the downstream side of the gate G2 is a conveyance path 16 that simply allows the banknote P to pass therethrough.
[0022]
The banknotes P distributed through the gate G2 and transported through the torsion transport path of the front / back reversing mechanism 14 are reversed.

The banknote P that has been turned upside down through the front / back reversing mechanism 14 and the banknote P that has passed through the transport path 16 without passing through the front / back turning mechanism 14 are both connected to the gate G3 via the junction 18. It is sent. At this time, the processing time of the banknote P that passes through the gate G2 and reaches the junction 18 through the front / back reversing mechanism 14 is the same as the transport time of the banknote P that passes through the transport path 16 and reaches the junction 18. In addition, the length of the transport path 16 is set. Thereby, the banknote P conveyed through the front / back reversing mechanism 14 and the banknote P passed through the transport path 16 pass through the merging portion 18 at the same timing, and all the banknotes P are subjected to the same condition regardless of the processing form. Can be processed.
[0024]
The conveyance path on the downstream side of the gate G3 is branched in two directions, and the conveyance direction of the bills P is selectively switched in two directions by selectively switching the gate G3 between two positions.
[0025]
One conveyance path branched rightward in the figure on the downstream side of the gate G3 forms a horizontal conveyance path 19 extending substantially horizontally above the plurality of stacking units 20-25. On the horizontal conveyance path 19, five gates G <b> 5 to G <b> 9 are provided for distributing and collecting the banknotes P to be conveyed to any one of the six accumulation units 20 to 25.
[0026]
The banknotes P that are selectively distributed by the gate G5 located on the most upstream side of the horizontal transport path 19 are stacked on the stacking unit 20, and the banknotes P that are selectively distributed by the gate G6 are stacked on the stacking unit 21, and the gate G7. The banknotes P that have been selectively distributed by the bank G are stacked in the stacking unit 22, the banknotes P that are selectively distributed by the gate G8 are stacked in the stacking unit 23, and the banknotes P that are selectively distributed by the gate G9 are stacked. 24 or the collecting unit 25.
[0027]
An accumulation portion 27 of the sealing device 26 is provided at a position branched to the left in the figure on the downstream side of the gate G3. The sealing device 26 forms, for example, a bundle of banknotes P by accumulating 100 banknotes P, winding a paper band, and sealing it.
[0028]
The banknotes P of a specific denomination assigned with a paper band are sent (accumulated) to the stacking unit 27 of the sealing device 26 according to a rule described later. On the other hand, banknotes P other than the specific denomination are stacked on any of the stacking units 20 to 25 described above.
[0029]
The banknotes P accumulated in the accumulating unit 27 via the gate G3 are sent to the sealing unit 29 by the supply unit 28 and sealed by the paper band supplied from the band supply unit 29a. A bundle of banknotes P sealed every predetermined number is carried out of the apparatus via a conveyor (not shown).
[0030]
The sealing unit 29 receives a predetermined number of banknotes P accumulated in the accumulating unit 27, and at a position offset from one side in the longitudinal direction (the rear side of the deposit processing machine 1 in this embodiment). A band is wound along the short direction, and a predetermined number of banknotes are sealed to form a bundle.

A drive shaft 35 as a support arm is bridged between the two side plate portions 34b, 34b via bearings 36, 36. Two rubber rollers 37 a and 37 b are attached to the drive shaft 35. The outer peripheral surfaces of these two rubber rollers 37a and 37b are formed of a rubber material in order to increase the frictional force. Two corresponding rubber rollers 38a and 38b are in rolling contact with the two rubber rollers 37a and 37b, respectively. The two rubber rollers 38 a and 38 b are attached to the shaft 40 via a bearing 39. Both end portions of the shaft 40 are fitted into elongated holes 41 formed in the side plate portions 34b and 34b of the support frame 34, and are urged downward by springs 42 provided outside the side plate portions 34b and 34b. That is, the two rubber rollers 38a and 38b are pressed against the corresponding two rubber rollers 37a and 37b, respectively, and these four rubber rollers 37a, 37b, 38a, and 38b function as correction rollers.
[0035]
The rubber rollers 37a, 37b, 38a, and 38b are disposed in a nested manner between three pairs of transport belts 49a, 49b, and 49c that extend through the posture correction device 11 along the transport path 7. That is, the pair of rubber rollers 37a and 38a on the front side of the apparatus is disposed between the first and second pair of conveying belts 49a and 49b, and the pair of roller 37b and 38b on the rear side of the apparatus is the first and third pairs. Between the pair of conveyor belts 49a and 49c.

At the same timing, the drive shaft 35 of the second correction unit 33 is rotated by an angle α in the direction of the arrow 83 in the figure. In this manner, the bill P is rotated by rotating the drive shaft 35 of the second correction unit 33 in a state where the bill P is clamped by the rubber rollers 37a and 38a and 37b and 38b of the second correction unit 33.

[0063]
FIG. 7 is a schematic view of the first correction unit 32 as viewed from above the conveyance path 7.
[0064]
In other words, it is assumed that the skew α and the shift x ₀ to the extent shown by the solid line in FIG. 7 are generated in the banknote P conveyed to the first correction unit 32 by the conveyance path 7.
[0065]
In this state, when the control unit 90 determines that the bill P (Pa) is sent to the first correction unit 32 based on a detection signal of a sensor (not shown) on the transport path 7, the control signal is sent to the posture correction control unit 97. Output. As a result, the posture correction control unit 97 drives and controls the stepping motor 54 of the first correction unit 32 (ST1). By this driving, the rubber rollers 37a, 37b, 38a, 38b of the first correction unit 32 are rotated in the transport direction at a peripheral speed equal to the peripheral speed of the transport belt pairs 49a-49c.
[0066]
Further, when the bill P passes through the posture detection sensor 70, a detection signal from the posture detection sensor 70 is output to the posture correction control unit 97.
[0067]
As shown in FIG. 7, the posture correction control unit 97 uses a detection signal from the posture detection sensor 70, as shown in FIG. Inclination amount in the conveyance direction, skew angle α [°]) α, displacement amount x ₀ [mm] from the center position (predetermined position) 7a of the conveyance path 7 and the length in the conveyance direction of the bill P (short of the bill P) The length of the end side [mm]) 1 is determined (ST2).
[0068]
The posture correction control unit 97 uses the determined conveyance amount deviation of the bill P, the skew amount, the length in the conveyance direction of the bill P, and the interval D between the rubber rollers 37a and 37b as parameters, and a driving angle of tan θ = x ₀ / l. θ is calculated (ST3).
[0069]
That is, the drive angle θ is
[Equation 3]

It satisfies.
[0070]
Next, the posture correction control unit 97 drives and controls the stepping motor 48 of the first correction unit 32 based on the calculated drive angle θ and the current position of the drive shaft 35 of the first correction unit 32. (ST4). By this drive, the drive shaft 35 is rotated to the position where the correction is made.
[0071]
As a result, when the banknote P (Pb) passes through the first correction unit 32, the movement for correcting the positional deviation is performed by the rubber rollers 37a, 37b, 38a, and 38b. In this case, the angle rubber roller 37a with respect to a direction crossing the determine bidirectional drive shaft 35, 37b, 38a, the time and the banknote P is conveyed by 38b, the correction amount _{x 0} is determined.
[0072]

Calculated by the posture correction control unit 97. Then, the stepping motor 48 is rotationally driven so as to rotate the drive shaft 35 of the first correction unit 32 by the angle θ as shown by an arrow 81 in FIG. At this time, the cylindrical shaft 43 and the shaft 44 of the first correction unit 32 rotate in opposite directions, but the one-way clutch 55 rotates idly, so the rotation speed of the first correction unit 32 does not change.
[0073]
If the banknote P is sent into the 1st correction | amendment part 32 in this state, the said banknote P will be conveyed, clamped and restrained by the rubber rollers 37a, 37b, 38a, and 38b. The bills P conveyed by the rubber rollers 37a, 37b, 38a, 38b are directed in a direction T ′ shifted by θ with respect to the center line 7a of the conveyance path 7. At this time, the bill P is directed in the direction of the arrow T ′ while maintaining the skew angle α, and only the positional deviation in the width direction is corrected.
[0074]
Next, the timing when the tip of the banknote P that has passed through the first correction unit 32 passes through the sensor 82, that is, the banknote P (Pc) is sandwiched between the rubber rollers 37 a, 37 b, 38 a, and 38 b of the second correction unit 33. At the restrained timing, the second correction unit 33 is rotated by α in the direction of the arrow 83 in the figure. Thus, the inclination of the banknote P (Pd) is caused by the rotation of the second correction section 33 in a state where the rubber rollers 37a, 37b, 38a, and 38b of the second correction section 33 clamp the banknote P. It is corrected.
[0075]
The banknote P in which the shift and the skew are continuously corrected by the above-described series of control operations is transported to the downstream detection unit 12 as the banknote P in the correct attitude with the transport attitude corrected and centered.
[0076]
Moreover, about the banknote P without skew and a shift among the banknotes P sent to the attitude | position correction apparatus 11, a correct attitude | position is not carried out by not rotating the rotating shafts 35 and 35 of the 1st and 2nd correction | amendment parts 32 and 33. It is conveyed to the detection unit 12 immediately after being kept. In the present embodiment, the correct posture is a reference posture in which one end side along the longitudinal direction of the bill P is orthogonal to the center line 7a of the transport path 7 and the center of the bill P is located on the center line 7a.

In the above embodiment, when the posture correction control unit 97 determines the shift amount x ₀ , the skew angle α, and the short edge length l of the banknote P, the shift amount x ₀ , the skew angle α, and the short end are determined. Although the case where θ at which tan θ = x ₀ / l is calculated by the posture correction control unit 97 using the side length l and the distance D between the rubber rollers 37a and 37b as parameters has been described, the present invention is not limited thereto, and the shift amount x _{Since the} drive angle θ of tan θ = x ₀ / l with respect to ₀ , the skew angle α, and the length l of the short edge is tabulated in the memory, it can be processed without being calculated by the attitude correction control unit 97. May be.
[0078]
In this case, the memory 91 stores an operation program or is used for data storage. The amount of inclination of the banknote P in the transport direction, the amount of misalignment from a predetermined position, and the length of the banknote P in the transport direction. A drive angle table 91a is provided as storage means for storing in advance the drive angle of the drive shaft 35 as the support arm, using the two rubber rollers (position correction rollers) 37a and 37b as parameters.
[0079]
The posture correction control unit 97 determines the transfer position deviation amount of the banknote P, the skew amount, the length of the banknote P in the transfer direction based on the transfer position deviation amount of the banknote P, the skew amount, and the length of the banknote P in the transfer direction. The drive angle of the drive shaft 35 of the first correction unit 32 using the distance between the rubber rollers 37a and 37b of the first correction unit 32 as a parameter is read from the drive angle table 91a of the memory 91. The drive shaft 35 is rotationally controlled based on the current position of the drive shaft 35 of the first correction unit 32.
[0080]
Next, the correction operation by the first correction unit 32 of the posture correction apparatus 11 configured as described above will be described with reference to the flowchart shown in FIG.
[0081]
In other words, it is assumed that the skew α and the shift x ₀ to the extent shown by the solid line in FIG. 7 are generated in the banknote P conveyed to the first correction unit 32 by the conveyance path 7.
[0082]
In this state, when the control unit 90 determines the feeding of the banknote P to the first correction unit 32 based on a detection signal of a sensor (not shown) on the conveyance path 7, the control signal is output to the posture correction control unit 97. Accordingly, the posture correction control unit 97 controls driving of the stepping motor 54 of the first correction unit 32 (ST11). By this driving, the rubber rollers 37a, 37b, 38a, 38b of the first correction unit 32 are rotated in the transport direction at a peripheral speed equal to the peripheral speed of the transport belt pairs 49a-49c.
[0083]
Further, when the bill P passes through the posture detection sensor 70, a detection signal from the posture detection sensor 70 is output to the posture correction control unit 97.
[0084]
As shown in FIG. 7, the posture correction control unit 97 uses a detection signal from the posture detection sensor 70, as shown in FIG. 7, the skew amount (the bill P of the banknote P) as the conveyance state of the banknote P sent to the posture correction device 11 through the conveyance path 7. Inclination amount in the conveyance direction, skew angle α [°]) α, displacement amount x ₀ [mm] from the center position (predetermined position) 7a of the conveyance path 7 and the length in the conveyance direction of the bill P (short of the bill P) The end side length [mm]) l is determined (ST12).
[0085]
The posture correction control unit 97 stores the drive angle of the drive shaft 35 of the first correction unit 32 in the memory 91 based on the determined conveyance position deviation amount of the banknote P, the skew amount, and the length of the banknote P in the transport direction. Is read from the driving angle table 91a (ST13).
[0086]
Next, the posture correction control unit 97 controls driving of the stepping motor 48 of the first correction unit 32 based on the read drive angle and the current position of the drive shaft 35 of the first correction unit 32 ( ST14). By this drive, the drive shaft 35 is rotated to the position where the correction is made.
[0087]
As a result, when the bill P passes through the first correction unit 32, the rubber rollers 37a, 37b, 38a, and 38b are moved to correct the positional deviation of the first correction unit 32. In this case, the angle rubber roller 37a with respect to a direction intersecting the conveying direction of the drive shaft 35, 37b, 38a, the time and the banknote P is conveyed by 38b, the correction amount _{x 0} is determined.
[0088]
Next, a method for calculating the drive angle θ of the first correction unit 32 will be described.

It is a point on the bill P to be played. Accordingly, since the straight line MM ′ and the straight line R′R coincide with the conveyance direction of the first correction unit 32 by the rubber rollers 37a and 37b, they are orthogonal to (intersect) the straight line LR.
[0092]
Here, in the coordinate system of FIG. 7, the point R ′ reaches the point R at the moment when the banknote P passes through the first correction unit 32, as the point M reaches the point M ′.
