     TECHNICAL FIELD 
     The present invention relates to a bank-note processing device used for e.g. a vending machine, a money changing machine, a pachinko ball dispenser and a metal token dispenser. 
     BACKGROUND ART 
     In a main unit of dispensers handling bank-notes (including coupons), a bank-note processing device for judging the genuineness of an inserted bank-note and for storing only bank-notes regarded as genuine is normally equipped. 
     FIG. 20 is a conceptual cross-sectional side view of a major portion of a conventional bank-note processing device  1 . 
     This bank-note processing device  1  comprises a main body  2 , and a stacker  37  which is disposed on the rear face  2   a  of the main body  2 . 
     In the main body  2 , an L-shaped bank-note transfer passage  4  connected to a bank-note slot  3 , bank-note transporting means  11  for guiding a bank-note inserted from the bank-note slit  3  to the bank-note transfer passage  4 , shutter means  18  for opening/closing the bank-note transfer passage  4 , bank-note identification means  19  comprised of a magnetic head which judges the genuineness of the bank-note transported by the bank-note transporting means  11  after which the bank-note is passed through the shutter means  18 , bank-note shifting means  20  for shifting the bank-notes judged as genuine by the bank-note identification means  19  to the stacker  37  side one by one, and a bank-note reverse-flowing preventive lever  30  for preventing the bank-notes stored in the stacker  37  by the bank-note shifting means  20  sticking out into the bank-note transfer passage  4 , are disposed. 
     The L-shaped bank-note transfer passage  4  is comprised of a horizontal portion  4   a  which further comprises top and bottom chutes  5  and  6 , and a vertical portion  4   b  which further comprises chutes  7  and  8 , where the entire bottom chute  6  area of the horizontal portion  4   a  and upstream of the bottom chute  8  of the vertical portion  4   b  are integrated by a roughly L-shaped box  9 , as disclosed in the description of Japanese Patent Application No. Hei 10-141350 which the present applicant proposed in the past. The box  9  is removably attached to the main body  2  in the arrow A direction as the dash and dotted lines in FIG. 21 show, via the slide support means, which is not illustrated, formed on both side faces of the box  9  and on both sides of the inner surface of the main body  2 , which is for example, guide grooves and guide protrusions to be guided into the guide grooves. FIG. 21 is a conceptual plan view of a major portion depicting the operation of the conventional bank-note processing device, where the identical parts as FIG. 20 are denoted by the same numerals. 
     The bank-note transporting means  11  is comprised of a looped bank-note transporting belt  12 , which is stretched along the horizontal portion  4   a  and the vertical portion  4   b  of the bank-note transfer passage  4 , and belt driving means  17 , which is further comprised of pulleys  13 ,  14 ,  15  and  16  for driving and rotating the bank-note transporting belt  12 , as shown in FIG.  20 . 
     The bank-note shifting means  20  is disposed on both sides of the main body  2  shown in FIG. 20 in the longitudinal direction, and is comprised of a pair of bank-note guide drums  21  which are supported so as to rotate in one direction with the top and bottom ends as shafts, as disclosed in the description of Japanese Patent Application No. Hei 5-276592, which the present applicant proposed in the past. On the cylindrical surface of the bank-note guide drum  21 , a slit  22  for inserting the edge of a bank-note in the width direction is formed along the bank-note transfer passage  4 , and this slit  22  is positioned to match the bank-note transfer passage  4  at the initial position, as shown in FIG. 22, which is a conceptual cross-sectional view of a major portion of the bank-note processing device. For details on the bank-note shifting means  20 , refer to the description in Japanese Patent Application No. Hei 5-276592. 
     The bank-note reverse-flowing preventive lever  30  is disposed between the pair of bank-note guide drums  21 , and is comprised of an L-shaped lever  25  which is rotatably supported with the shaft  26  as a center, and the lever  25  further comprises a long shaft  25   a  which is set to be a length shorter than the outer diameter  21   a  of the bank-note guide drums  21 , and a short shaft  25   b  connected to urging means  28 , which is further comprised of a spring  27  supported by a spring support section  31  disposed on the main body  2 . 
     In the case of the long shaft  25   a , the front end area  25   c  can freely come out of the hole  29  formed in the main body  2  toward the bank-note guide drum  21 , and force is always exerted on the front end  25   e  toward the bank-note transfer passage  4  side by the urging means  28 . For the short shaft  25   b , a stop  32 , for controlling the lever not to rotate for more than a predetermined angle toward the bank-note transfer passage  4  side, is formed at the front end  25   d.    
     According to such a bank-note processing device  1 , when a bank-note  101  (FIG. 22) is inserted into the bank-note slot  3 , as shown in FIG. 20, the presence of the bank-note  101  is detected by the bank-note detection sensor, and the inserted bank-note  101  is horizontally transported to the right direction in the drawing along the horizontal portion  4   a  of the bank-note transfer passage  4  by the transporting force of the bank-note transporting belt  12  which rotates counterclockwise, that is normal rotation, based on the detection signal. At the same time, the shutter means  18  (FIG. 20) is driven, by which the shutter is moved to the left direction in the drawing and the vertical portion  4   b  of the bank-note transfer passage  4  is opened. 
     When the inserted bank-note  101  is horizontally transported to the right direction in the drawing along the horizontal portion  4   a  of the bank-note transfer passage  4  by the normal rotation of the bank-note transporting belt  12 , and is then transported upward at roughly a 90 degree angle along the vertical portion  4   b  of the bank-note transfer passage  4 , the genuineness of the inserted bank-note  101  is judged by the bank-note identification means  19  disposed at the vertical portion  4   b  of the bank-note transfer passage  4 . 
     If the bank-note identification means  19  judges the inserted bank-note  101  as counterfeit, the bank-note transporting belt  12  rotates in reverse (clockwise rotation), so as to return the inserted bank-note  101  through the bank-note slot  3 . 
     If the bank-note identification means  19  judges the inserted bank-note  101  as genuine, the bank-note transporting belt  12  continues normal rotation based on the detection signal, so as to transport the inserted bank-note  101  downstream of the bank-note transfer passage  4 . 
     When the front end  101   a  of the inserted bank-note  101  is inserted into the bottom ends  22   a  of the slits  22  of the bank-note guide drums  21 , the inserted bank-note  101  is caught between the edge of the slits of the bank-note guide drums  21  and the bank-note transporting belt  12  (FIG.  20 ), therefore the inserted bank-note  101  is transported to the arrow B direction in FIG. 22 along the slits  22  by the transporting force of the bank-note transporting belt  12 . 
     When a sensor, not illustrated, detects that the bottom end  101   b  of the bank-note  101  has reached a predetermined position in the slits  22  of the bank-note guide drums  21 , as shown in FIG. 23 where the identical parts as FIG. 22 are denoted by the same numerals, normal rotation of the bank-note transporting belt  12  (FIG. 20) stops and the bank-note guide drums  21  rotate in directions opposite from each other at a same phase, by which the bank-note  101  inserted in the slits  22  parallel shifts to the stacker  37  side, as the arrow C in FIG. 23 shows. 
     When the bank-note  101  parallel shifts to the stacker  37  side by the rotation of the bank-note guide drums  21 , the bottom end  101   b  of the bank-note  101 , which has a normal longitudinal dimension, contacts the long shaft  25   a  of the lever  25  and rotates the lever  25  with the shaft  26  as the center, as shown in FIG. 24, where the identical parts as FIG. 22 are denoted by the same numerals, therefore the lever  25  gradually moves into the hole  29 , and the bank-note  101  parallel shifts to the stacker  37  side by the rotation of the bank-note guide drums  21 . 
     When the bank-note  101  parallel shifts to the stacker  37  side by the rotation of the bank-note guide drums  21  and reaches the stacker  37 , that is, when the slit  22  where the bank-note  101  is inserted, reaches the outer diameter  21   a  of the bank-note guide drums  21  by the rotation of the bank-note guide drums  21 , the bank-note  101  is caught between the stacker plate, which is not illustrated, and the external surface of the bank-note guide drums  21  via the stack spring, which is not illustrated, and at the same time, the bank-note  101  is pushed by the chute  34  (FIG.  28 ), which constitutes the bank-note transfer passage  4  and shifts toward the stacker  37  side according to the rotation of the bank-note guide drums  21 , and as a result, the bank-note  101  is released from the slits  22 , and is stored in the stacker  37  without fail. 
     Since the length of the long shaft  25   a  of the lever  25  is set to be shorter than the outer diameter  21   a  of the bank-note guide drums  21 , the bottom end  101   b  of the bank-note  101  leaves from the front end  25   e  of the long shaft  25   b  before the slit  22 , where the bank-note  101  is inserted, reaches the outer diameter  21   a  of the bank-note guide drums  21  by the rotation of the bank-note guide drums  21 , and the lever  25  returns to the initial position by the exerting force of the urging means  28 , as shown in FIG. 25, where identical parts as FIG. 22 are denoted by the same numerals. 
     As a consequence, the inserted bank-note  101  is stacked and stored in the stacker  37  and the bottom end  101   b  engages with the bank-note reverse-flowing preventive lever  30 , as shown in FIG. 26, where the identical parts as FIG. 22 are denoted by the same numerals, and this prevents the bank-note  101  stored in the stacker  37  from sticking out into the bank-note transfer passage  4  blocking transporting of the bank-note to be stored next. 
     Also in the conventional bank-note processing device  1 , the stacker  37  is removably attached to the rear face  2   a  of the main body  2 , as shown in FIG. 20, therefore the stacker  37  is separated from the main body  2  to collect the bank-notes stored in the stacker  37 . 
     Also the box  9  of the bank-note processing device  1  is comprised of the entire bottom chute  6  area constituting the horizontal portion  4   a  of the bank-note transfer passage  4  and upstream of the bottom chute  8  constituting the vertical portion  4   b , which are integrated, and is removably attached to the main body  2  in the arrow A direction via the above mentioned slide support means as shown in FIG.  20  and FIG. 21, so when a maintenance, inspection and cleaning of the bank-note transporting means  11 , shutter means  18  or bank-note identification means  19  is performed, the operator slides the box  9  to the opposite side of the main body  2  via the above slide support means while holding the box  9  so as to separate the box  9  from the main body  2 , after which maintenance, inspection and cleaning are performed. 
     According to the above mentioned conventional bank-note processing device  1 , the length of the long shaft  25   a  of the lever  25  is set to be shorter than the outer diameter  21   a  of the bank-note guide drums  21 , as shown in FIG. 25, however, the longitudinal dimension of the bank-notes vary, and if a bank-note whose longitudinal dimension is short is inserted and this bank-note is stored in the stacker  37 , the bank-note  102  does not engage with the front end  25   c  of the bank-note reverse-flowing preventive lever  30 , and is pushed by other bank-notes already stored in the stacker  37  or by the stacker plate, not illustrated, and as a result, the roughly center part  102   c  in the width direction sticks out into the bank-note transfer passage  4 , and the bank-note  102  once stored in the stacker  37  may interfere in transporting a bank-note to be stored next, as shown in FIG.  27  and in FIG. 28, which is a conceptual top view of FIG.  27 . 
     In particular, since the bank-notes  102  stored in the stacker  37  tend to swell toward the bank-note transfer passage  4  side by air which enters into the center area  102   c  in the width direction, the above concern is more serious. 
     Also according to the above mentioned conventional bank-note processing device  1 , the stacker  37  is removably attached to the main body  2  and stores the bank-note  101  transported from the main body  2  as shown in FIG. 20, therefore if the stacker  37  is separated from the main body  2  to collect the bank-notes stored in the stacker  37 , the bank-notes  101  stored in the stacker  37  tend to drop through the opening of the stacker  37  which is formed directly toward the rear face  2   a  of the main body  2 . 
     Also according to the above mentioned conventional bank-note processing device  1 , the box  9  is comprised of the entire bottom chute  6  area constituting the horizontal portion  4   a  of the bank-note transfer passage  4  and upstream of the bottom chute  8  constituting the vertical portion  4   b , which are integrated, and is removably attached to the main body  2  in the arrow A direction via the slide support means, as shown in FIG.  21 . So in order to perform maintenance, inspection and cleaning of the bank-note transporting means  11  or the bank-note identification means  19 , the operator slides the box  9  to the opposite side of the main body  2  via the slide support means while holding the box  9 , and after separating the box  9  from the main body  2  in this way, maintenance, inspection and cleaning is performed. 
     This means that during maintenance, inspection and cleaning operation of the bank-note transporting means  11  or bank-note identification means  19 , the box  9  must be held and maintenance, inspection and cleaning operation must be performed with one hand, which makes the operation troublesome. 
     With the foregoing in view, it is an object of the present invention to provide a bank-note processing device which can prevent a bank-note stored in the stacker from sticking out into the bank-note transfer passage and interfering in the processing of the bank-note to be transported next as much as possible. 
     It is a second object to provide a bank-note processing device which can prevent a bank-note stored in the stacker from sticking out into the bank-note transfer passage and interfering in the processing of the bank-note to be transported next as much as possible, and can prevent the drop of bank-notes stored in the stacker during bank-note collection as much as possible. 
     It is a third object to provide a bank-note processing device which simplifies the maintenance, inspection and cleaning of various equipment disposed on the bank-note transfer passage, and improves the work efficiency.

The bent part  25   g  of the first lever  25  is inserted into the first shaft  26  which is inserted into both ends of the notch  72 . The protruding section  25   f  formed on the short shaft  25   b  constitutes the first stop  32 . 
     At the front end  25   c  of the long shaft  25   a  of the first lever  25 , a notch  73  directed upward is formed and the second shaft  74  passes through roughly at the center of the notch  73 . Also in the notch  73 , the shaft  75  constituting the second stop  76  passes through at a location slightly below the second shaft  74  toward the bank-note transfer passage  4  side. 
     The first urging means  28  is comprised of a spring  27  where one end  27   a  is supported by a spring support section  84  disposed in the stacker  71  and the other end  27   b  is connected to the short shaft  25   b  of the first lever  25 . 
     The rear end  79   b  of the second lever  79  is comprised of a piece  79   c  which is formed at the bank-note transfer passage  4  (FIG. 1) side, and a shaft support section  79   b  having a cross-section of roughly an arc shape, where the second shaft  74  is inserted, and the entire rear end  79   b  is inserted into the notch  73  of the first lever  25 . 
     The second urging means  77  is comprised of a spring  78  where one end  78   a  loops the second shaft  74  and is connected to the long shaft  25   a  of the first lever  25  and the other end  78   b  is connected to the second lever  79 . 
     In the bank-note reverse-flowing preventive lever  80  structured in this manner, the first lever  25  is rotatably supported with the first shaft  26  as the center, and force is constantly exerted on the first lever  25  to the bank-note transfer passage  4  side by the first urging means  28 . The rotation of the first lever  25  toward the bank-note transfer passage  4  side is controlled to be less than at a predetermined rotation angle by the protruding section  25   f  formed on the first lever  25  contacting the bottom face  72   a  of the notch  72 . The second lever  79  is rotatably supported with the second shaft  74  as the center and force is constantly exerted on the second lever  79  to the bank-note transfer passage  4  side by the second urging means  77 . The rotation of the second lever  79  is controlled to be less than at a predetermined rotation angle by the piece  79   c  contacting the shaft  75 . 
     Operation of the above mentioned bank-note processing device  51  will now be explained. 
     Since the bank-note transfer passage  4 , the bank-note transporting means  11 , the shutter means  18  and the bank-note identification means  19  of the bank-note processing device  51  perform operations the same as the prior art, operation after insertion of the bank-note judged as genuine into the slits  22  of the bank-note guide drums  21  will be described here. 
     In this bank-note processing device  51 , the slits  22  of the bank-note guide drums  21  are positioned so as to match the bank-note transfer passage  4  at the initial position, as shown in FIG. 3, where the identical parts as FIG. 2 are denoted by the same numerals. 
     In the bank-note reverse-flowing preventive lever  80 , at the initial position, the front end  25   e  of the long shaft  25   a  of the first lever  25  sticks out through the hole  54  in the direction parallel with the bank-note transfer passage  4  and toward the bank-note guide drums  21  side, since the protruding section  25   f  is in contact with the bottom face  72   a  of the notch section  72 , and the entire second lever  79  sticks out through the hole  54  in the parallel direction as the bank-note transfer passage  4  and toward the bank-note guide drums  21  side, since the piece  79   c  is in contact with the shaft  75 . 
     When the bank-note  101 , which is genuine, is transported along the bank-note transfer passage  4  by the bank-note transporting means  11 , the front end is inserted into the bottom end  22   a  of the slits  22  of the bank-note guide drums (FIG.  22 ), and the inserted bank-note  101  is caught between the edge of the slits  22  of the bank-note guide drums  21  and the bank-note transporting belt  12  (FIG.  1 ), therefore the inserted bank-note  101  is transported further upstream along the slits  22  by the transporting force of the bank-note transporting belt  12 . 
     When a sensor, not illustrated, detects that the bottom end  101   b  of the bank-note  101  reaches a predetermined position in the slits  22  of the bank-note guide drums  21 , as shown in FIG. 3, normal rotation of the bank-note transporting belt  12  stops, and at the same time, the bank-note guide drums  21  rotate in opposite directions at a same phase, and as a result, the bank-note  101  inserted into the slits  22  parallel shifts toward the stacker  71  side. 
     When the bank-note  101  parallel shifts toward the stacker  71  side by the rotation of the bank-note guide drums  21 , the bottom end  101   b  of the bank-note  101  having a normal longitudinal dimension contacts the long shaft  25   a  of the first lever  25 , presses the first lever resisting the force exerted by the first urging means  28 , and rotates the first lever  25  in the clockwise direction with the first shaft  26  as the center, as shown in FIG. 4, where the identical parts as FIG. 3 are denoted by the same numerals, therefore the first lever  25  gradually moves back into the hole  54  from the rear end side of the long shaft  25   a , and the bank-note  101  parallel shifts more toward the stacker  71  side by the rotation of the bank-note guide drums  21 . When the bank-note  101  parallel shifts toward the stacker  71  side by the rotation of the bank-note guide drums  21 , the position, where the bottom end  101   b  of the bank-note  101  contacts the first lever  25 , gradually shifts toward the front end  25   e  of the first lever  25  side. The second lever  79  rotates together with the first lever  25  while maintaining the initial position where the piece  79   c  is in contact with the shaft  75 . 
     When the bank-note  101  parallel shifts more toward the stacker  71  side by the rotation of the bank-note guide drums  21 , the bottom end  101   b  of the bank-note  101  leaves from the first lever  25  and contacts the second lever  79 , as shown in FIG. 5, where the identical parts as FIG. 3 are denoted by the same numerals. Then the first lever  25  gradually rotates counterclockwise with the first shaft  26  as the center by the force exerted by the first urging means  28 . The second lever  79 , on the other hand, rotates clockwise with the second shaft  74  as the center resisting the force exerted by the second urging means  77  by the force pressing the bottom end  101   b  of the bank-note  101 , and the front end  79   a  gradually moves back into the hole  54 , therefore the bank-note  101  parallel shifts more toward the stacker  71  side by the rotation of the bank-note guide drums  21 . When the bank-note  101  parallel shifts toward the stacker  71  side, the position, where the bottom end  101   b  of the bank-note  101  contacts the second lever  71 , gradually shifts toward the front end  79   a  side of the second lever  79 . 
     When the bank-note  101  parallel shifts more toward the stacker  71  side by the rotation of the bank-note guide drums  21 , the bottom end  101   b  of the bank-note  101  leaves from the front end  79   a  of the second lever  79 , as shown in FIG. 6, where the identical parts as FIG. 3 are denoted by the same numerals. When the bottom end  101   b  of the bank-note  101  leaves from the front end  79   a  of the second lever  79 , the second lever  79  rotates counterclockwise with the second shaft  74  as the center by the force exerted by the second urging means  77 , and the first lever  25  rotates counterclockwise with the first shaft  26  as the center by the force exerted by the first urging means  28 . And finally, the first and second levers  25  and  79  return to respective initial positions. 
     When the bank-note  101  then parallel shifts even more toward the stacker  71  side by the rotation of the bank-note guide drums  21  and reaches the stacker  71 , the bank-note  101  is caught between the stacker plate, not illustrated, and the external surface of the bank-note guide drums by the stack spring, not illustrated, and at the same time, the bank-note  101  is pressed by the chute  34  (FIG. 28) which constitutes the bank-note transfer passage  4  and moves to the stacker  71  side according to the rotation of the bank-note guide drums  21 , therefore the bank-note  101  is released from the slits  22 , and as a result, the bank-note  101  is loaded and stored in the stacker  71  without fail, as shown in FIG. 7, where the identical parts as FIG. 3 are denoted by the same numerals. When the bank-note  101  in the slits  22  reaches the stacker  71 , the slits  22  of the bank-note guide drums  21  reach the position at the outer diameter  21   a  of the bank-note guide drums  21 . 
     So the inserted bank-note  101  having a normal longitudinal dimension is stacked and stored in the stacker  71 , as shown in FIG. 7, and the bottom end  101   b  of the bank-note  101  engages with the bank-note reverse-flowing preventive lever  80 , by which the potential problem where the bank-note  101  stored in the stacker  71  is pressed by another bank-note stored in the stacker  71  before or by the stacker plate, not illustrated, and roughly the center  101   c  in the width direction of the bank-note  101  sticks out into the bank-note transfer passage  4 , interfering in transporting the bank-note to be stored next can be prevented as much as possible. 
     If a bank-note inserted in the slits  22  and to be parallel shifted toward the stacker  71  side is a bank-note  102  which has a short longitudinal dimension, when the bank-note  102  parallel shifts toward the stacker  71  side by the rotation of the bank-note guide drums  21 , the bottom end  102   b  of the bank-note  102  contacts the second lever  79 , as shown in FIG. 8, where the identical parts as FIG. 3 are denoted by the same numerals, and at the same time, the bottom end  102   b  of the bank-note  102  presses the second lever  79  resisting the force exerted by the second urging means  77 , and rotates the second lever  79  clockwise with the second shaft  74  as the center, by which the second lever  79  gradually moves back from the moving direction of the bank-note  102 , and the bank-note  102  parallel shifts more toward the stacker  71  side by the rotation of the bank-note guide drums  21 . When the bank-note  102  parallel shifts toward the stacker  71  side by the rotation of the bank-note guide drums  21 , the position, where the bottom end  102   b  of the bank-note  102  contacts the second lever  79 , gradually shifts toward the front end  79   a  of the second lever  79  side. Since the second lever  79  rotates resisting the force exerted by the second urging means  77 , the first lever  25  slightly rotates clockwise with the first shaft  26  as the center by the resilience of the second urging means  77 , resisting the force exerted by the first urging means  28 . 
     When the bank-note  102  parallel shifts more toward the stacker  71  side by the rotation of the bank-note guide drums  21 , the bottom end  102   b  of the bank-note  102  leaves from the front end  79   a  of the second lever  79 , as shown in FIG. 9, where the identical parts as FIG. 3 are denoted by the same numerals. Then the second lever  79  rotates counterclockwise with the second shaft  74  as the center by the force exerted by the second urging means  77 , and the first lever  25  also rotates counterclockwise with the first shaft  26  as the center by the force exerted by the first urging means  28 . And finally, both the first and second levers  25  and  79  return to the respective initial positions. 
     When the bank-note  102  then parallel shifts even more toward the stacker  71  side by the rotation of the bank-note guide drums  21 , and the bank-note  102  in the slits  22  reaches the stacker  71 , the bank-note  102  is caught between the stacker plate, not illustrated, and the external surface of the bank-note guide drums by the stack spring, not illustrated, and at the same time, the bank-note  102  is pressed by the chute  34  (FIG. 28) which constitutes the bank-note transfer passage  4  and moves to the stacker  71  side according to the rotation of the bank-note guide drums  21 , therefore the bank-note  102  is released from the slits  22 , and as a result, the bank-note  102  is loaded and stored in the stacker  71  without fail, as shown in FIG. 10, where the identical parts as FIG. 3 are denoted by the same numerals. When the bank-note  102  in the slits  22  reaches the stacker  71 , the slits  22  of the bank-note guide drum  21  reach the position at the outer diameter  21   a  of the bank-note guide drums  21  shown in the drawing. 
     This means that even a bank-note  102  which has a short longitudinal dimension can be stacked and stored in the stacker  71  and the bottom end  102   b  of the bank-note  102  engages with the front end  79   a  of the second lever  79  of the bank-note reverse-flowing preventive lever  80 , as shown in FIG. 10, therefore the potential problem that the bank-note  102  once stored in the stacker  71  is pressed by another bank-note stored in the stacker  71  before or by the stacker plate, not illustrated, and roughly the center  102   c  in the width direction of the bank-note  102  sticks out into the bank-note transfer passage  4 , interfering in transporting the bank-note to be stored next can be prevented as much as possible. 
     In this way, in the bank-note processing device  51 , the bank-note reverse-flowing preventive lever  80  is rotatably supported via the first shaft  26 , and is comprised of the first lever  25  which is shorter then the outer diameter  21   a  of the bank-note guide drums  21 , the first energy exerting means  28  which constantly exerts force on the first lever  25  toward the bank-note transfer passage  4  side, the first stop  32  which controls the first lever  25  not to rotate more than at a predetermined rotation angle toward the bank-note transfer passage  4  side, the second lever  79  which is rotatably supported at the front end  25   c  of the first lever  25  via the second shaft  74 , the second stop  76  which controls the second lever  79  not to rotate more than at a predetermined angle toward the bank-note transfer passage  4 , and the second urging means  77  which constantly exerts force on the second lever  79  toward the bank-note transfer passage  4  side, therefore at the initial position where the bank-note reverse-flowing preventive lever  80  returns after storing the bank-note in the stacker  71 , the length of the portion sticking out through the hole  54  toward the bank-note guide drums  21  is longer compared with the prior art, and as a result, the bank-note stored in the stacker  71  engages with the bank-note reverse-flowing preventive lever  80  without fail, even if the inserted bank-note is a bank-note  102  having a short longitudinal dimension. 
     Also in this bank-note processing device  51 , the second lever  79  is rotatably supported, via the second shaft  74 , at the front end  25   c  of the rotatable first lever, which is shorter than the outer diameter  21   a  of the bank-note guide drums  21  and on which force is constantly exerted toward the bank-note transfer passage  4  side by the first urging means  28 , and force is constantly exerted on the second lever  79  toward the bank-note transfer passage  4  side by the second urging means  77 , therefore the bottom end of the bank-note leaves from the front end  79   a  of the lever  79  before the bank-note reverse-flowing preventive lever  80 , which is shifted in parallel with the bank-note transfer passage  4  by the rotational driving of the bank-note guide drum  21 , reaches the outer diameter  21   a  of the bank-note guide drums, that is, before the bank-note reaches the stacker  71 , and as a result, the bank-note reverse-flowing preventive lever  80  returns to the initial position without fail when the bank-note is stored in the stacker  71 . As a consequence, the potential problem where the bank-note reverse-flowing preventive lever  80  engages with the bottom end of the bank-note pressed by another bank-note stored in the stacker  71  before and cannot return to the initial position can be prevented as much as possible. 
     Even when the inserted bank-note is a bank-note  102  having a short longitudinal dimension, the bank-note  102  can be engaged with the bank-note reverse-flowing preventive lever  80  without fail when the bank-note  102  is stored in the stacker  71 , and the potential problem where the bank-note  102  once stored in the stacker  71  is pressed by another bank-note stored in the stacker  71  before or by the stacker plate, not illustrated, and roughly the center  102   c  in the width direction of the bank-note sticks out into the bank-note transfer passage  4 , interfering in transporting the bank-note to be stored next can be prevented as much as possible. 
     In other words, when the bank-notes of which longitudinal dimensions vary are stored in the stacker  71 , the bank-note processing device  51  can engage the bank-notes with the bank-note reverse-flowing preventive lever  80  without fail, and the potential problem where the bank-note once stored in the stacker  71  sticks out into the bank-note transfer passage  4  interfering in transporting the bank-note to be stored next can be prevented as much as possible. 
     Particularly, the bank-notes stored in the stacker  71  tend to swell toward the bank-note transfer passage  4  side by air which enters into the center area of the bank-notes in the width direction, therefore having this bank-note reverse-flowing preventive lever  80  is effective to prevent the above potential problems. 
     Also in the bank-note processing device  51 , when an inserted bank-note is positioned at a predetermined position in the slits  22  of the bank-note guide drums  21 , the bank-note can be engaged with the bank-note reverse-flowing preventive lever  80  even if the bank-note is positioned above the predetermined position due to a positioning error, and is stored in the stacker  71  in this state, therefore the potential problem where the bank-note stored in the stacker  71  is not engaged with the bank-note reverse-flowing preventive lever  80  and sticks out into the bank-note transfer passage  4  interfering in transporting the bank-note to be stored next can be prevented as much as possible. 
     Now the structure of the stored bank-note drop prevention means which prevents the bank-note stored in the stacker from dropping through the lower part of the stacker when the stacker is separated from the main body stated in (2) related to the second aspect of the present invention will be explained. 
     The stored bank-note drop prevention means  91  is comprised of the above mentioned bank-note reverse-flowing preventive lever  80 , as shown in FIG. 11, which is a conceptual cross-sectional view of a major portion depicting the state where the stacker is separated from the main body. The bank-note reverse-flowing preventive lever  80  is disposed at the protruding section  92  which is on the front face  71   a  of the stacker  71 , roughly at the center of the lower part of the body  35  of the stacker  71 , as shown in FIG.  11  and FIG. 12, which depicts the front face of the stacker. On the front face  71   a  of the stacker  71 , the protruding section  93  is also disposed, roughly at the center of the upper part of the body  35 . 
     In the bank-note processing device  51  comprising this stored bank-note drop prevention means  91 , as shown in FIG. 11, when the protruding section  92  disposed at the lower part of the stacker  71  is inter-fitted into the interfit groove, not illustrated, which is formed on the rear face  52   a  of the main body  52 , not illustrated, roughly at the center in the longitudinal direction, the notch  72  is positioned at the position of the notch  53  of the main body  52 , as shown in FIG. 2, so as to form a hole  54 . Also when the protruding section  93  formed at the upper part of the stacker  71  shown in FIG. 11 is inter-fitted with the attachment groove, which is formed on the rear face  52   a  of the main body  52  and at the upper part in the longitudinal direction, the stacker  71  can be attached to the main body  52 , as shown in FIG.  1 . 
     FIG. 13 is a conceptual plan view depicting the front face of the stacker when the separated stacker is attached to the main body. 
     The stacker  71  can be separated from the main body  52  as shown in FIG. 11 if the operation in reverse of the above procedure is performed, and in the stacker  71  separated from the main body  52  in this way, the bank-note  101  stored in the stacker  71  is confined roughly at the center  101   c  and at the lower parts of the side faces of the bank-note  101  and the bottom end of the bank-note  101  by the first lever  25  and the second lever  79  of the bank-note reverse-flowing preventive lever  80 , therefore the potential problem where the bank-note  101  stored in the stacker  71  drops from the stacker  71  when the stacker  71  is separated from the main body is prevented as much as possible, which further improves safety in bank-note collection operation. 
     Now the structure of the box attachment/removal means stated in (3) related to the third aspect of the present invention will be explained. 
     The box  9  shown in FIG. 1 is a box  9  comprised of an L-shape in the cross-section where the entire bottom chute  6  area of the horizontal portion  4   a  constituting the L-shaped bank-note transfer passage  4  and the upstream part of the bottom chute  8  of the vertical portion  4   b , which are integrated, just like the prior art. The L-shaped bank-note transfer passage  4  comprises the horizontal portion  4  which is further comprised of chutes  6  and  7  and the vertical portion  4   b , which is further comprised of chutes  8  and  9 . 
     The box  9  is removably attached to the main body  52  by the attachment/removal means  61 , as shown in FIG. 14, where the identical portions as FIG. 1 are denoted by the same numerals, and is temporarily rotatably supported at the main body  52 . FIG. 14 is a conceptual cross-sectional view of a main portion of the bank-note processing device  51 , where the pulleys  15  and  16  and other parts disposed in the box  9  are not illustrated. 
     This attachment/removal means  61  comprises a guide groove  62  which is formed on both sides of the inner surface of the main body  52 , a guide protrusion  65  which is formed on both sides of the box  9  and is guided into the guide groove  62 , a guide protrusion escape hole  66 , which is formed at the end of the guide groove  62  directed upward, and a guide protrusion support hole  67  which is formed on both sides of the main body  52  and at the end  62   b  of the guide groove  62 . 
     In the bank-note processing device  51  having this attachment/removal means  61 , the guide protrusion  65  is inserted in one end  62   a  of the guide groove  62  in the initial state where the box  9  is attached to the main body  52  shown in FIG.  14 . 
     To separate the box  9  from the main body  52 , the guide protrusion  65  in the guide groove  62  is guided into the rear face  52   a  side of the main body  52  along the guide groove  62 , and the guide protrusion  65  is contacted to the end  62   b  of the guide groove  62  as shown in FIG. 15, where the identical parts as FIG. 14 are denoted by the same numerals. At this time, the guide protrusion  65  is inserted in the guide protrusion support hole  67 , but the guide protrusion  65  cannot be guided upward since the guide groove  62  is positioned at the upper part. 
     When the guide protrusion  65  is guided toward the front face  52   b  side of the main body  52  along the guide groove  62 , the guide protrusion  65  contacts a part  67   a  of the guide supporting hole  67  where the guide protrusion  65  is inserted as shown in FIG. 16, where the identical parts as FIG. 14 are denoted by the same numerals, and when the guide protrusion  65  is guided further upward along the shape of the guide supporting hole  67 , the guide protrusion  65  passes through the guide protrusion escape hole  66  as shown in FIG. 17, where the identical parts as FIG. 14 are denoted by the same numerals, and the engagement between the guide protrusion  65  and the guide groove  62  is cleared, therefore the box  9  can be separated from the main body  52  as shown in FIG. 18, where the identical parts as FIG. 14 are denoted by the same numerals. 
     The separated box  9  shown in FIG. 18 can be attached to the main body  52  if the above operation is executed in reverse. 
     In a state where the guide protrusion  65  is in contact with the end  62   b  of the guide groove  62  as shown in FIG. 15, the guide protrusion  65  is inserted in the guide protrusion supporting hole  67 , by which the box  9  is supported at the main body  52 , therefore if the operator supporting the box  9  by hand releases the box  9 , the box  9  rotates downward with the guide protrusion  65  as the center due to its own weight. 
     When the box  9  rotates for a predetermined angle, the base of the body of the box  9  disposed between the guide protrusion  65  contacts a notch, not illustrated, formed in the base of the main body  52 , so as to control the rotation of the box  9 , so the entire box  9  is supported at the main body  52  via the guide protrusion  65  and the guide support hole  67  as shown in FIG. 19, where the identical parts as FIG. 14 are denoted by the same numerals. 
     Since an open space is created in the upper part  9   a  of the box  9  supported at the main body  52 , the maintenance, inspection and cleaning of the bank-note transporting means  11 , the shutter means  18  or the bank-note identification means  19  can be performed using this space, and at that time, an operator need not hold the box  9 , which improves work efficiency. 
     If the above operation is performed after the box  9  is returned from the state where the box  9  is supported at the main body  52  to the state shown in FIG. 15 by rotating the box  9  counterclockwise with the guide protrusion  65  as the center, then the box  9  can be separated from the main body  52 . 
     As described above, in the bank-note processing device in accordance with the first aspect of the present invention, the bank-note reverse-flowing preventive lever comprises the first lever which is rotatably supported via the first shaft and is shorter than the outer diameter of the bank-note guide drum, the first urging means which constantly exerts force on the first lever toward the bank-note transfer passage side, the first stop which controls the first lever not to rotate more than at a predetermined rotation angle toward the bank-note transfer passage side, the second lever which is rotatably supported at the front end of the first lever via the second shaft, the second stop which controls the second lever not to rotate more than at a predetermined rotation angle toward the bank-note transfer passage side, and the second urging means which constantly exerts force on the second lever toward the bank-note transfer passage side, therefore at the initial position where the bank-note reverse-flowing preventive lever returns when the bank-note is stored in the stacker, the length of the portion sticking out through the hole toward the drums is longer compare with the prior art, and as a result, the bank-note stored in the stacker engages with the bank-note reverse-flowing preventive lever without fail, even if the inserted bank-note is a bank-note having a short longitudinal dimension. Also in the bank-note processing device in accordance with the first aspect of the present invention, the second lever is rotatably supported, via the second shaft, at the front end of the rotatable first lever, which is shorter than the outer diameter of the bank-note guide drums and on which force is constantly exerted toward the bank-note transfer passage side by the first urging means, and force is constantly exerted on the second lever toward the bank-note transfer passage by the second urging means, therefore the bottom end of the bank-note leaves from the second lever before the slits, which are shifted in parallel with the bank-note transfer passage, reaches the outer diameter of the bank-note guide drums by the rotary driving of the bank-note guide drum, that is, before the bank-note reaches the stacker, and as a result, the bottom end of the bank-note leaves the second lever and the bank-note reverse-flowing preventive lever returns to-the initial position without fail when the bank-note is stored in the stacker. As a consequence, the potential problem where the bank-note reverse-flowing preventive lever engages with the bottom end of the bank-note pressed by another bank-note stored in the stacker before and cannot return to the initial position can be prevented as much as possible. 
     Therefore, even when the inserted bank-note is a bank-note having a short longitudinal dimension, the bank-note can be engaged with the bank-note reverse-flowing preventive lever without fail when the bank-note is stored in the stacker, and the potential problem where the bank-note once stored in the stacker is pressed by another bank-note stored in the stacker before or by the stacker plate, not illustrated, and roughly the center in the width direction of the bank-note sticks out into the bank-note transfer passage interfering in transporting the bank-note to be stored next can be prevented as much as possible. 
     In other words, in the bank-note processing device in accordance with the first aspect of the present invention, when the bank-notes which longitudinal dimensions vary are stored in the stacker, the bank-note can be engaged with the bank-note reverse-flowing preventive lever without fail, and the potential problem where the bank-note once stored in the stacker sticks out into the bank-note transfer passage interfering in transporting the bank-note to be stored next can be prevented as much as possible. 
     Particularly, the bank-notes stored in the stacker  71  tend to swell toward the bank-note transfer passage side by air which enters into the center area in the width direction of the bank-notes therefore having this bank-note reverse-flowing preventive lever is effective to prevent the potential problems described above. 
     Also in the bank-note processing device in accordance with the second aspect of the present invention, the bank-note reverse-flowing preventive lever, which is disposed between the pair of bank-note guide drums when the stacker is attached to the main body so as to prevent the bank-notes stored in the stacker from sticking out into the bank-note transfer passage, is disposed in the stacker, so when the stacker is separated from the main body, this lever can prevent the bank-notes stored in the stacker from dropping, and as a result, a bank-note processing device which can prevent potential problems where the bank-notes stored in the stacker stick out into the bank-note transfer passage interfering in processing the bank-note to be transported next and can prevent bank-notes stored in the stacker from dropping when collecting bank-notes as much as possible. 
     In the bank-note processing device in accordance with the third aspect of the present invention, the attachment/removal means comprises a guide groove which is formed on both sides of the inner surface of the main body, a guide protrusion which is formed on both sides of the box and is guided into the guide groove, a guide protrusion escape hole which is formed just before the end of the guide groove directed upward of the guide groove, and a guide protrusion support hole which is formed on both sides of the main body and at the end of the guide groove, therefore the box is slidably attached to the main body when the guide protrusion is inserted in the guide groove via the guide protrusion escape hole, and is rotatably supported at the main body and the box is separated from the main body by removing the guide protrusion from the guide groove via the guide protrusion escape hole when the guide protrusion is inserted in the guide protrusion support hole, as a consequence, if the box rotates downward with the guide protrusion as the center due to its own weight in a state where the guide protrusion is in contact with the end of the guide groove, an open space is created at the upper part of the box. 
     If the maintenance, inspection and cleaning of the bank-note transporting means or bank-note identification means are performed using this space, the operator can perform these operations using both hands since it is not necessary to hold the box while performing these operations, which makes the operation simpler and improves work efficiency, and as a result, a bank-note processing device which simplifies maintenance, inspection and cleaning operations of various devices disposed on the bank-note transfer passage and improves work efficiency can be provided.
