BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This present invention is an improvement in a compact bank note dispensing device which can dispense a bank note from a safe to a dispensing slot. More particularly, the present invention relates to a bank note dispensing device which can monitor the dispensing of each bank note and can capture and recycle any extra bank notes that had been accidentally forwarded for dispensing. 
   2. Description of Related Art 
   Compact bank note dispensing device are known as shown in U.S. Pat. No. 6,098,837. The term Bank note which is used in this specification embraces a check, a certificate, coupon ticket or exchange ticket, and other documents shaped like a bank note and can be stored in a stack-like manner. The prior art discloses a safe which has a bank note rejection section which can be detachable to present the loss of bank notes. When a sensor detects that there is an erroneous duplication of bank notes, the duplicated bank note is usually guided to the reject section and isn&#39;t dispensed. 
   However, if a substantial number of duplicated bank notes are rejected and stored in the rejection section, the supply of bank notes will run out quickly and the safe will have to be charged with new bank notes frequently. 
   OBJECTS AND SUMMARY OF THE INVENTION 
   A first purpose of the present invention is to recycle any transported duplicated bank notes which are initially rejected. 
   A second purpose of the present invention is to downsize a bank notes dispensing device which can recycle the duplicated bank notes. 
   The bank note dispensing device comprises a safe which stores bank notes and has a dispensing slot, a bank note let off device which is located in the safe, a transporting device which transports the bank notes to the dispensing slot, a checking device which checks the bank notes which are to be released from the safe, a diverting device which diverts to a recycling passageway bank notes based on a signal from the checking device, and a recycling device which transports the bank notes in the recycling passage back to the transporting device. 
   When the duplicated bank notes are dispensed from the safe, the bank notes are guided to the recycling passage by the diverting device. Afterwards the bank notes are recycled back to the safe or are dispensed to the dispensing slot, as a result, they are recycled. Therefore a frequent changing of the supply of bank notes for the safe is avoided. 
   In the present invention, a recycling device is desirable, because it includes a one by one let off device which positions the bank notes in the recycling passageway. The bank notes can be stored in the recycling passageway, and they are let off from the recycling device one by one. Therefore they are recycled back to the safe or are dispensed from the recycling passageway to the dispensing slot. 
   Also, in the present invention, the dispensing time can become faster, because the recycling bank note are stored in the recycling passageway adjacent the transport device until the bank notes are dispensed to the dispensing slot in predetermined numbers. A recycling device is desirable, because the recycling device has a receiving device which receives the bank notes in the recycling passageway. In this structure, when the recycling bank notes are returned to the safe, they can be dispensed to the dispensing slot again. Therefore the bank note dispensing device is small, because it can be a small return of the safe which is mounted in the dispensing device. 
   In this present invention, a checking device is desirable, because it checks if there is any doubling up of bank notes and the duplicated bank notes are transported by the diverting device, the recycling passage and the recycling device. The receiving device is desirable, because it includes a let off device, and a direction changing device which changes the transporting direction of the let off device. 
   In this structure, a part of the receiving device can be used as a part of the let off device. Therefore the device uses fewer parts, which are smaller and inexpensive. 
   In this present invention, the recycling passageway is desirable, because it is located between the transporting device and the safe. In this structure, the transporting device and the recycling device can be located in a narrow space. Therefore the bank note dispensing device requires only a small area. 
   The recycling device is desirable, because it includes a lifting device which separates the bank notes from a bottom board of the safe. In this structure, when the bank note is received in the recycling passage, the lowest bank note is separated from the bottom by the lifting device.

As shown in  FIG. 11 , driver  156  and first roller  21  is driven by first motor  134  through the first transmission mechanism  135 . 
   Next, driving mechanism  232  of the one by one dispensing device  96  and first transporting roller  18  is explained. As shown in  FIG. 11 , second worm gear  239  is fixed at the output shaft of second motor  234  engages with a second worm wheel  241  which is rotatable supported on fixed shaft  240 . 
   The gear (not shown) which is fixed at second worm wheel  241  engages with gear  243  which is fixed at driving shaft  112 . Gear  243  engages with first gear  22  which is fixed at the side of first roller  21 . 
   As shown in  FIG. 8 , gear  245  is fixed on shaft  244  of one by one dispensing device  96  and is driven by gear  247  through idle gear  246 . 
   Therefore roller  101  of one by one dispensing device  96  is driven by second motor  234  through one way clutch  111 . 
   Next, driving device  17  of let off device  3  is explained by referring to FIG.  15  and FIG.  16 . Fourth motor  249  is fixed at bracket  248 . Third worm gear  252  is fixed on the output shaft  25  of fourth motor  249 . 
   Third worm gear  252  engages with the third worm wheel  254  which is fixed on shaft  253  which is rotatable supported at bracket  248 . Pinion gear  255  is integrated with third worm gear  252  and engages with gear  257  which is fixed at shaft  256  which is also rotatable supported on bracket  248 . 
   Second shaft  256  is rotatable supported on a pair of bearings  258  and  259 . First stopper  260  is fixed in the middle of second shaft  256 . 
   Drive gear  261  is fixed on second shaft  256  and is located adjacent to first stopper  260 . 
   First slipping disc  263  is a ring and is fixed at the side of drive gear  261 . Second slipping disc  264  is a ring and is rotatable supported at second shaft  256  and is located adjacent to first slipping disc  263 . 
   The friction disc (not shown) is made of felt and is wedged between first slipping disc  263  and second slipping disc  264 . First slipping clutch  262  is made up of first slipping disc  263 , second slipping disc  264  and the friction disc. 
   First pusher  268  is a cylinder with a flange and is located between second stopper  267  and second slipping disc  264 . Second stopper  267  is fixed on second shaft  256  which is located between bearing  258  and second slipping disc  264 . Spring  269  is located between first pusher  268  and second stopper  267 . Therefore second slipping disc  264  is pushed to first slipping disc  263  by spring  269 . 
   Second spring  270  is wound around second shaft  256  which is a second one way clutch and comes face to face with first pusher  26 . When second shaft  256  doesn&#39;t rotate, second spring  270  is rotatable about second shaft  256 . 
   When second shaft  256  rotates in the involute direction of second spring  270 , the inner surface of second spring  270  has a frictional contact with the exterior surface of second shaft  256 . Therefore second spring  270  is caught on second shaft  256 , as a result, the bore diameter of second spring  270  becomes smaller. Therefore second spring  270  has hard contact with second shaft  256  and rotates integral with second shaft  256 . 
   Second slipping disc  264  rotates integral with second shaft  256  because the end of second spring  270  hooks to slit  271  of second slipping disc  264 . The transmission force from second slipping disc  264  to first slipping disc  263  is determined by the pushing force of spring  269  and the coefficient of sliding friction between first slipping disc  263  and second slipping disc  264 . Drive gear  261  engages with idle gear  273  and is rotatable supported on first cantilever  272  which is extended from first pusher  268 . 
   Next drive changing device  274  is explained by referring to  FIGS. 15 and 16 . Drive changing device  274  includes receiving driving gear  275 , second slipping clutch  278 , second cantilever  282 , third slipping clutch  284 , and receiving idle gear  285 . Third stopper  286  is fixed at second shaft  256  and is located adjacent to bearing  259 . Receiving driving gear  275  is rotatable supported by second shaft  256  and is located between drive gear  261  and the third stopper  286 . 
   Second slipping clutch  278  includes a third slipping disc  276  which is rotatable supported at the side of receiving driving gear  275 . Fourth slipping disc  277  is rotatable supported on second shaft  256  and is located between the first stopper  260  and the third slipping disc  276 . 
   A second friction disc (not shown) is a ring and is made of felt and is wedged between third slipping disc  276  and fourth slipping disc  277 . Second slipping clutch  278  includes third slipping disc  276 , fourth slipping disc  277  and the friction disc. 
   Third slipping clutch  284  is explained. Fifth slipping disc  279  is fixed at the side of receiving driving gear  275 . Sixth disc  280  is rotatable supported on second shaft  256  and is located between third stopper  286  and fifth slipping disc  279 . A third friction disc (not shown) is a ring and is made of felt and is wedged between the fifth slipping disc  279  and the sixth disc  280 . 
   Ring  281  is rotatable supported on second shaft  256 . Second cantilever  282  is fixed at ring  281 . Spring  283  is located between third stopper  286  and second cantilever  282  and pushes second cantilever  282  towards the side of receiving driving gear  275 . Third slipping clutch  284  includes fifth slipping disc  279 , sixth disc  280  and the friction clutch. 
   Sixth disc  280  is pushed towards the side of fifth slipping disc  279  by spring  283  to second cantilever  282 . Receiving idle gear  285  is rotatable supported on the end of second cantilever  282 . Receiving idle gear  285  engages with receiving driving gear  275 . 
   When first cantilever  272  and second cantilever  282  pivot on second shaft  256 , idle gear  273  and receiving idle gear  285  can be engaged with gear  287  is located at unit section  115  of safe  2 . When second shaft  256  rotates in the counterclockwise direction as shown in  FIG. 15 , second spring  270  becomes smaller in diameter because second spring  270  has contact with second shaft  256 . Therefore one way clutch is connected. As a result, first pusher  268  rotates towards the same direction. 
   Second slipping disc  264  rotates towards the same direction by first pusher  268 . Therefore first slipping disc  263  is rotated towards the same direction at a predetermined torque which is installed in the first slipping clutch  262 . In this situation, first cantilever  272  rotates toward the same direction therefore idle gear  273  engages with gear  287 . 
   Fourth slipping disc  277  rotates the same direction to first stopper  260 . Sixth disc  280  rotates in the same direction to third stopper  286 , spring  283  and second cantilever  282 . Therefore receiving driving gear  275  rotates in the counterclockwise direction and the torque is installed in second slipping clutch  278  and third slipping clutch  284 . 
   Receiving idle gear  285  doesn&#39;t engage with gear  287  because second cantilever  282  rotates in the clockwise direction. Therefore gear  287  rotates in the counterclockwise direction at the FIG.  2 . 
   Rollers  124  and  125  are rotated in the counterclockwise direction by gear  287  through to belts  127  and  128 . The lowest bank note  12  has contact with rollers  124  and  125  and it is ejected to the outside of safe  2 . 
   When second shaft  256  rotates in the clockwise direction as shown in  FIG. 15 , second spring  270  becomes larger in diameter because the inner surface of second spring  270  has friction contact with second shaft  266 . Therefore the one way clutch is disconnected as a result the drive gear  261  doesn&#39;t rotate. Idle gear  273  doesn&#39;t engage away from gear  287  because first cantilever  272  rotates in the clockwise direction as shown in FIG.  15 . 
   Receiving driving gear  275  rotates in the same direction towards second slipping clutch  278  and the third slipping clutch  284 . At the same time, the receiving idle gear  285  engages with gear  287  because the second cantilever  282  rotates in the same direction. Therefore gear  287  rotates in the clockwise direction as shown in FIG.  2 . 
   Rollers  124  and  125  are rotated in the clockwise direction by gear  287  through belts  127  and  128 . Rollers  124  and  125  can draw bank note  12  into safe  2  because they rotate in the clockwise direction. Therefore rollers  124  and  125  can be a let off device  3  or a receiving device  99  depending on the rotating direction. Drawing device  152  includes rollers  124  and  125  and drive changing device  274 . 
   Driving device  288  of package dispensing device  53  is explained. As shown in  FIG. 2 , guiding roller  57  is rotated by third motor  289 . Driving device  288  is third motor  289 . 
   The layout of the sensors is explained, first bank note sensor  291  is located at the outside of shutter  299 . Second sensor  292  is located at receiving slot  19 . Third sensor  293  is located at first transporting path  301 . Fourth sensor  294  is located at the section of fourth roller  55 . Fifth sensor  295  is located at reject transporting roller  74 . Sixth sensor  296  is located at bank note dispensing slot  5 . Seventh sensor  297  is located at recycling passage  7 . 
   The distance between the first sensor  291  and the third sensor  293  is the same length as a bank note  12 . Length sensor  298  includes first sensor  291  and third sensor  293 . The second sensor  292  is a transparent photoelectric method sensor and has the function of a passing sensor and also a double bill sensor. Checking sensor  302  is the second sensor  292 . The bank note sensor could be changed to a reflecting type or mechanical type. 
   Position sensor  303  detects a first projection  304  and a second projection  305 . As shown in  FIG. 13 , position sensor  306  is a proximity sensor and detects a lifted guide rod  313 . 
   Next, a control block diagram is explained by referring to FIG.  17 . Bank note sensors  291  through to  303 , position sensor  303  and  306  are connected to a micro computer  321 . The payout signal  322  from an exchanger is input to micro computer  321 . 
   Micro computer  321  operates based on a program stored in ROM  323  and controls first motor  134 , second motor  234 , third motor  289  fourth motor  249 , solenoid  66 , second solenoid  79  and third solenoid  231 . 
   Next, the operation is explained by referring to FIG.  18  through to FIG.  20 . Safe  2  is drawn from storing section  11 , and bank notes  12  are stored in storing section  113 . Lid  117  is closed and is locked by key  119 . 
   Bank note pusher  129  pushes bank notes  12  to the bottom  157 . 
   The lowest bank note  12  has contact with rollers  124  and  125 . Safe  2  is inserted in storing section  11  and is locked to body  10  by a locking device (not shown). 
   Next the operation, when a bank note  12  is paid out is explained. At step  1 , when dispensing signal PO from the control circuit of the vending machine, etc. is checked, it goes to step  2 . Therefore first motor  134  and second motor  234  rotate. 
   When the first motor  134  rotates, second roller  25  rotates in the clockwise direction through a first transmission mechanism  135  and a second gear  26 . First arraying roller  41 , third roller  28 , fourth transporting roller  51 , fifth roller  76  and second arraying roller  83  are rotated in the same direction by second gear  149 . 
   First transporting roller  13 , first arraying roller  41  and fourth roller  55  rotate and bank note  12  is released to second storing device  52 . Reject transporting roller  74  rotates to move the bank note  12  to reject storing section  114 . 
   Second arraying roller  83  rotates for sending the bank note  12  to recycle storing device  73 . First gear  22  is rotated in the clockwise direction by second motor  234  through second transporting mechanism  212 . Therefore first roller  21  rotates for sending a bank note  12  to the first transporting roller  18 . 
   At step  3 , fourth motor  249  rotates. Second shaft  256  is rotated in the counterclockwise direction as shown in  FIG. 15  by fourth motor  249  through the third worm gear  252 , third worm wheel  254 , the pinion gear  255  and the gear  257 . 
   Second spring  270  is rotated by second shaft  256  which rotates in the counterclockwise direction, and screws second shaft  256  up tight, as a result, and second slipping disc  264  rotates. First slipping disc  263  is rotated to the predetermined torque through the friction disc. 
   First cantilever  272  and first pusher  268  are rotated in the counterclockwise direction by second shaft  256 . Therefore idle gear  273  engages with driven gear  126  in unit section  115 . In this situation, second cantilever  282  rotates in the same direction by the rotation of counterclockwise direction of second shaft  256 . Receiving idle gear  285  doesn&#39;t engage with driven gear  126 . 
   Roller  124  and  125  are rotated in the counterclockwise direction by driven gear  126  through belts  127  and  128 . 
   The lowest bank note  12  is sent to bank note exit  123  by roller  124  and  125 . 
   Only one bank note  12  passes through bank note exit  123  and is transported to receiving slot  19 . The bank note  12  is transported to first transporting passage  33  by second transporting roller  23  through first transporting roller  13  and it arrives to first arraying device  36 . 
   Bank note  12  is transferred from second transporting roller  23  to first arraying roller  41 , shortly after the bank note  12  derails from second transporting roller  23 . First arraying roller  41  pushes at a predetermined force a bank note  12  to first guiding board  34 . Cylindrical section  44  and slanting section  45  on first arraying roller  41  have contact with bank note  12 , when it deforms. 
   Bank note  12  which moves upward as shown in  FIG. 5  is turned in the clockwise direction, because it is guided by first arraying roller  41  and first guiding board  34 . The contact pressure of cylindrical section  44  on bank note  12  is larger than the contact pressure of slanting section  45 , as a result, the bank note  12  receives a turn force by cylindrical section  44 . The lower end of side edge  325  of bank note  12  has contact with third guide wall  38 . 
   The bank note  12  is turned in the clockwise direction as it fulcrums about the lower end. Therefore the side edge length of bank note  12  has contact with third guide wall  38 . Afterwards, side edge  325  of bank note  12  is guided by third guide wall  38  and arrives at third transporting roller  27 . After bank note  12  is nipped by third transporting roller  27 , it goes off from first arraying roller  41 . At the third transporting roller  27 , the running direction of bank note  12  is changed to a right angle by third press roller  29  and fourth press roller  31 . 
   At step  4 , first sensor  291  distinguishes between the overlap of bank notes  12 . The output signal of second sensor  292  which is a transmission type is compared to a standard level. As a result, any dispensed double bank notes  12  is detected. When a dispensed double bank notes  12  is detected, the program goes to step  11  of subroutine SUB 1 . When dispensed double bank notes  12  are not detected, the program goes to step  5 , and the length of bank note  12  is judged. 
   The distance between first sensor  291  and third sensor  293  is slightly longer than the length of bank note  12 . Therefore if first sensor  291  and third sensor  293  output the detecting signal at the same time, it is an abnormal situation, and as a result the program goes to step  21 . If it is a normal situation, the program goes to step  6 . 
   At step  6 , the signal of bank note  12  of third sensor  293  is judged. In other words, when dispensed bank note  12  from safe  2  is detected, the program goes to step  7 . At step  7 , fourth motor  249  is stopped, as a result, the let off of bank note  12  from safe  2  is stopped. 
   At step  61 , when the bank note signal is detected over a predetermined time period, the program goes to step  31  because jamming may be occurring. 
   At step  31 , all actuators (first motor  134  and second motor  234  etc.) are stopped as shown in  FIG. 21 , and an abnormal sign is displayed to a visual display, and all control processes are stopped. 
   Next, at step  8 , the bank note detecting signal of fourth sensor  294  is determined. When a bank note detecting signal is not received, it is a normal situation and the program goes to step  9 . At step  8 , when the bank note signal is detected over a predetermined time period, the program goes to SUB 3  because jamming is occurring or at least an abnormal process. 
   If it is a genuine bank note, diverting board  65  is kept at the solid line. Therefore the bank note is guided to fourth roller  55  by diverting board  65  while wedged between fourth press roller  31  and third roller  28 . Second roller  25  transports the bank note  12  to checking sensor  302  which is located between hollow  56  of tray  50  and second transporting device  15 . 
   At step  9 , the bank note signal which is outputted from fourth sensor  294 , is counted until the predetermined number is reached and the program then goes to step A. In other words, bank notes  12  are stored in a predetermined number in a second storing device  52 . If the bank note signal is not a predetermined number, the program returns to step  3  and a second bank note  12  is dispensed from safe  2 . This process is repeated until predetermined numeral is reached. 
   At step A, first motor  134 , second motor  234  and fourth motor  249  are stopped. As a result, let off device  3 , body  10  and storing device  16  stop. 
   At step B, third motor  289  rotates. Guiding roller  57  is rotated in the counterclockwise direction as shown in FIG.  2 . At step C, when position sensor  303  detects second projection  62 , the program goes to step D. At step C, third motor  289  stops, and the program goes to step E. 
   At step C, when sensor  10  doesn&#39;t output the second projection  62  detecting signal within a predetermined time period, it is identified at step C 1 . At step C 1 , the program goes to subroutine SUB 3  and it executes the trouble shooting. The bank notes  12  in second storing device  52  are moved to bank note dispensing slot  5 , as a result the end of the bank notes  12  protrudes from between guiding board  63  and  64 . 
   At step E, when sixth sensor  296  detects the bank notes  12 , the program goes to the next step. As a result, the program is stopped. If sixth sensor  296  doesn&#39;t detect the bank notes  12  at step E, the program goes to subroutine SUB 3 . As a result, the program executes a trouble shooting procedure. 
   The protruding bank note  12  from guiding board  63  and  64  are removed by the user. When the bank notes  12  are not pulled by person while with a predetermined time period, a alarm can be sounded. 
   When overlapping bank notes  12  are detected at step  4 , solenoids  66  and second solenoid  79  are excited at step  1  of subroutine SUB 1 . Diverting board  65  is slightly pivoted in the clockwise direction by solenoid  66  at step  1  and closes the passage to fourth roller  55  and opens the passage to recycling passage  7 . Also, reject guiding board  78  is slightly pivoted in the clockwise direction by second solenoid  79  and closes the passage to reject transporting roller  74  and opens the passage to recycling passage  7 . 
   Therefore bank note  12  is guided by diverting board  65  and is guided by reject guiding board  78 . While bank note  12  is wedged between third roller  28  and fourth press roller  31  and the bank note  12  arrives at second arraying device  72 . Recycling bank note  80  is pushed to reverse surface  95  by spring  98  at second arraying device  72 , afterwards it is wedged between second arraying roller  83  and reverse surface  95 . 
   Recycling bank note  80  is wedged between second arraying roller  83  and reverse surface  95 , and passes between third roller  28  and fourth press roller  31 . Recycling bank note  80  is changed to a new position by second arraying roller  83  and first arraying roller  41  and the side is pushed to first guiding wall  84  and is arrayed. 
   Therefore the end of recycling bank note  80  is stopped by the overlap section  107  which is located between fixed rollers  103  and  104  and seventh press roller  102 , as a result, recycling bank note  80  is stored in recycle storing device  73 . In this situation, second arraying roller  83  has contact with the upper section of recycling bank note  80 , however second arraying roller  83  can not be rotated because friction clutch  94  slips. 
   Therefore recycling bank note  80  is not injured by the rotation of second arraying roller  83 , because the transfer of torque of friction clutch  94  is set. Also, the bank note  12  doesn&#39;t become wave shape. 
   In this situation, spring  98  pushes the upper section of recycling bank note  80  to the first guiding board reverse side  67 . 
   When next recycling bank note  80  is transported to recycle storing device  73  while recycling bank note  80  is stored at recycle storing device  73 , the end of the next recycling bank note  80  is guided to the root of spring  98  by the slanting surface  97  of spring  98  (shown in FIG.  4 ). The end of recycling bank note  80  is guided by the slant of spring  98  and has contact with the stored recycling bank note  80  from the side of safe  2 . Therefore the next recycling bank note  80  is pushed to the stored recycling bank note  80  by the end of spring  98 . 
   The next recycling bank note  80  is arrayed by second arraying roller  83  and third guiding wall  86 . In this manner, recycling bank note  80  is arrayed at the safe  2  side. 
   At step  12 , when bank notes  12  are extracted from bank note dispensing slot  5 , the output of sixth sensor  296  becomes “ON” and the program goes to step  13 . If sixth sensor  296  outputs the bank note detecting signal over predetermined time period at step  121 , the program goes to subroutine SUB 3  and executes an abnormal program response. 
   At step  3 , third solenoid  231  is excited. Therefore core  204  moves to the right (shown in FIG.  14 ), as a result, cam board  194  slides in the same direction. 
   Slanting section  206  of cam hole  203  pushes up shaft  202  in the elongate hole  193  by the slide of cam board  194 . Pinion gear  192  engages with driven gear  189  and driving gear  227 . 
   At step  14 , first motor  134  rotates. Crank  186  of lifting driver  155  is rotated by first motor  134 , therefore pushes down pin  187  and lever  182 . Lever  182  pivots in the counterclockwise direction shown in FIG.  13  and pushes down pin  179 . 
   Transferring base  178  moves upwards and at the same time first pushing rod  173  is guided by bush  171 , second pushing rod  174  is guided by bush  172  and guiding rod  177  is guided by bush  176 . 
   When transferring base  178  moves to our upwards position at step  15 , as a result, position sensor  306  does not output a detecting signal, and the program goes to step  16 . When position sensor  306  detects a signal over a predetermined time period at step  151 , the program goes to subroutine SUB 3 , because lifting device  154  has not pushed up. 
   At step  16 , first motor  134  stops. Therefore transferring base  178  is located at its most upward position. As a result, first pushing rod  173  pushes up first receiving section  163  of bank notes lifting device  153  and second pushing rod  174  pushes up second receiving section  168 . 
   Therefore first lever  159  and second lever  164  pivot in the clockwise direction on each shaft  161  and shaft  165  as shown in FIG.  22  and push upwards each first pin  162  and second pin  166 . First pin  162  and second lever  164  push upward bank note  12 , therefore they make up the receiving section  326  which has a triangular shape. 
   At step  17 , second motor  234  and fourth motor  249  reverse rotation. First roller  21  rotates in the counterclockwise direction by second motor  234  through second transporting mechanism  212  and first gear  22 . 
   Driving shaft  112  rotates in the counterclockwise direction through gear  243 , idle gear  246  and gear  245  by fourth motor  249  as shown in FIG.  8 . Therefore the diameter of the spring of the one way clutch  111  shrinks to contact with driving shaft  112 . As a result, one way clutch  111  lets in the clutch and rotates shaft  100  in the same direction. Roller  101  rotates in the counterclockwise direction by shaft  100  as shown in FIG.  9 . 
   Seventh press roller  102  has contact with roller  101  and rotates in the clockwise direction. Therefore only recycling bank note  80  which has contact with seventh press roller  102  is pulled down and is let off towards the side of first transporting roller  13  by roller  101 . 
   The recycling bank note  80  is guided to the points of contact between first roller  21  and first pressing roller  20  by the guiding board, and is guided to bank note exit  123  through receiving slot  19 . Second shaft  256  rotates in the clockwise direction by fourth motor  249  as shown in FIG.  15 . 
   Therefore idle gear  273  is unengaged from driven gear  126 , because first cantilever  272  rotates in the clockwise direction. Also, spring  269  is increased to the inner diameter for rotation of second shaft  256 , therefore drive gear  261  does not rotate. 
   Receiving idle gear  285  engages with driven gear  126 , because second cantilever  282  is pivoted in the clockwise direction by second shaft  256 . Therefore receiving driving gear  275  rotates in the clockwise direction by the predetermined torque which is set up by second slipping clutch  278  and third slipping clutch  284 . Rollers  125  and  126  rotate in the clockwise direction through receiving idle gear  285 , driven gear  126 , belts  127  and  128  as shown in FIG.  2 . 
   Therefore the end of recycling bank note  80 , which is transported from bank note exit  123  to storing section  113  by first transporting roller  13 , goes between roller  124  and the bank note  12  passes through receiving section  326 . Recycling bank note  80  is transported between roller  125  and bank note  12  by roller  124  is transported. 
   Therefore the end of recycling bank note  80  is stopped by lid  117 , as a result, roller  124  and  125  stops the rotation, because the rotating resistance of roller  124  and  125  increases and second slipping clutch  278  and third slipping clutch  284  slips. As a result, recycling bank note  80  does not receive any damage and is not undulated by rollers  124  and  125 . 
   When second sensor  292  does not detect the bank note signal at step  18 , the program goes to step  19 . If second sensor  292  does not output the bank note signal within a while predetermined time period at step  181 , the program goes to subroutine  3 . At step  19 , second motor  234  stops. 
   Therefore, one by one dispensing device  96  and first transporting roller  13  stop their operation. 
   When first sensor  291  does not detect bank note  12  at step  1 A, the program goes to step  1 B. At step  1 A 1 , if first sensor  291  does not detect a bank note signal within a predetermined time period, the program goes to subroutine SUB 3 . 
   At step SUB 3 , a trouble shooting procedure is initiated. 
   At step  1 B, after a predetermined clocking, the program goes to step  1 C therefore fourth motor  249  stops. As a result, receiving device  99  operates with enough time while recycling bank note  80  is stored in storing section  113 . 
   At step  1 D, when seventh sensor  297  detects a recycling bank note  80 , the program goes to step  1 E. In other words, when there is recycling bank note  80  at recycle storing device  73 , it is prepared to receive it. When there isn&#39;t recycling bank note  80  at recycle storing device  73 , the program finishes. 
   At step  1 E, third solenoid  231  is excited, next first motor  134  rotates at step  1 F. When position sensor  306  does not detect guiding rod  177  at step  1 G, first motor  134  stops at step  1 H. When a signal of position sensor  306  is not detected within a predetermined time period, the program goes to subroutine SUB 3  at step  1 G, and does trouble shooting. 
   Therefore lifting device  154  and bank notes lifting device  153  move downwards, and move upwards. As a result, receiving section  326  is formed between the lowest recycling bank note  80  and bottom  157 . At step  17 , other recycling bank notes  80  are stored in safe  2 . 
   When payout signal  322  is outputted, first the lowest recycling bank note  80  which has contact with roller  124  and  125  is let off from the safe  2 . 
   When length sensor  298  detects any abnormal length of a bank note  12  at step  5 , the program goes to step  21  of subroutine SUB 2  and solenoid  66  is excited. Therefore diverting board  65  slightly pivots in the clockwise direction and closes the passage to fourth roller  55  and opens the passage to recycling passage  7  as the dotted line shown in FIG.  2 . 
   At this situation, second solenoid  79  is not excited. Therefore reject guiding board  78  closes the passage to recycling passage  7  and opens the passage to reject transporting roller  74 . Abnormal length bank note  12  is guided to recycling passage  7  by diverting board  65 . 
   The bank note  12  is guided to reject transporting roller  74  by reject guiding board  78  and is transferred to reject transporting roller  74  while it is transported by third roller  28  and fourth press roller  31 . The bank note  12  is transported from receiving slot  121  to reject storing section  114  by reject transporting roller  74 , therefore any abnormal length bank note  12  is stored in reject storing section  114 . 
   When the output signal of fifth sensor  295  does not change with a predetermined time period at step  22 , the program goes to subroutine SUB 3  after it does trouble shooting. When fifth sensor  295  outputs the bank note nothing signal at step  22 , solenoid  66  is not excited at step  33 . Therefore, diverting board  65  goes back to the solid line position shown in FIG.  2 . Next the program goes to step  6 . 
   If a pair of bank notes  12  are misaligned, the bank notes  12  are judged to be in an abnormal situation at each step  4  and  5 . However, duplicate judge step takes priority at step  4 . 
   This present invention can store recycling bank note  80  at recycling passage  7 , and at next payout timing, the bank notes are let off to first transporting roller  18  in a one by one procedure. In this situation, a second double detecting sensor is located between one by one dispensing device  96  and first transporting roller  18 . 
   Also, this present invention can directly transport recycling bank note  80  to first transporting roller  18  by the one by one dispensing device  96 . 
   This present invention can directly transport bank note  12  from diverting device  6  to bank note dispensing slot  5 .
