The urging force that enables the maximum amount of bills S within the range to be clamped is generated by the kick spring 65 that is further compressed by the swing arm 60 and is in a predetermined clamped compression state. As shown in FIG. 1 (b), the position of the kick roller 62 at this time is a predetermined amount that allows the maximum amount of bills S within the capacity range of the deposit slot 20 to be clamped only with the bill pressing plate 50. It becomes a pinching swing position.

  In this way, the pinching spring 66 is compressed in the pinching compression state, that is, the pinching for detecting at the position of the detected portion 75 of the swing arm 60 that the position of the kick roller 62 has reached the pinching swinging position. A position detection sensor (clamping force detection means, position detection sensor) 77 is provided at a fixed position. That is, the clamping position detection sensor 77 detects the clamping force of the banknote S between the banknote holding plate 70 including the kick roller 62 and the banknote pressing plate 50. The clamping position detection sensor 77 detects whether or not the kicking spring 65 and the clamping spring 66 are in a predetermined clamping compression state, that is, whether or not the kicking roller 62 is rocked to a predetermined clamping rocking position. Based on the detection result, when the kick roller 62 does not swing to a predetermined sandwich swing position, the gripping force of the bill holding plate 70 and the bill pressing plate 50 against the bill S is increased. Detecting that a predetermined value has been reached. Even if the maximum amount of banknotes S is placed on the banknote stacking plate 12, this clamping force is applied to the banknote holding plate 70 and the banknote pressing plate 50 in a state where the support of all banknotes S is released by the banknote stacking plate 12. It is a value that can be sandwiched between.

  Here, the urging force of the kick spring 65 becomes impossible to hold the maximum amount of banknotes S between the banknote holding plate 70 and the banknote pressing plate 50 in a state where the support by the banknote stacking plate 12 is released. Yes. Further, in a state where the kick spring 65 and the pinching spring 66 are in the pinching compression state, the pinching force is too large, and it is impossible to kick out the banknote S properly by the kicking roller 62.

  The feeding roller 56 is capable of contacting the banknote S closest to the banknote holding plate 70 among the banknotes S in the deposit slot 20, and feeds out the banknote S kicked out by the kicking roller 62 toward the feeding outlet 72. It feeds out from 72 to the banknote conveyance path not shown. The separation roller 58 stops the banknote S other than the banknote on the side of the feeding roller 56 among the banknotes S kicked out by the kicking roller 62 toward the feeding outlet 72, so that a not-illustrated banknote transport path from the feeding outlet 72. The bills S to be fed out are separated one by one.

  Since the banknote stacking plate 12 can be moved up and down as described above, a notch 78 through which the separation roller 58 can pass is formed.

  A stacking posture failure detection sensor (stacking posture failure detection means) 81 is provided in the vicinity of the banknote stacking plate 12 in the normal position and in the vicinity of the upper side of the banknote stacking plate 12 in the retracted position. . The stacking posture defect detection sensor 81 retracts the banknote stacking plate 12 downward in a state where the banknotes S stacked on the banknote stacking plate 12 are sandwiched between the banknote pressing plate 50 and the banknote holding plate 70. Thus, the presence / absence of a defective stacking posture of the banknotes S is detected from the presence / absence of the downward protrusion of the banknotes S sandwiched between the banknote pressing plate 50 and the banknote holding plate 70. That is, in the stacked banknotes S, when there is a stacking posture failure banknote S (S1) in which the lower part is under the other banknote S, the banknote S stacked on the banknote stacking plate 12 is present. When the banknote stacking plate 12 is retracted downward in a state in which the banknote pressing plate 50 and the banknote holding plate 70 are sandwiched, the stacking posture defective banknote S (S1) protrudes downward due to its own weight and waist (inertia). Since the projecting portion Sa shown in FIGS. 1B and 2B is formed, the projecting portion Sa is detected by the integration posture defect detecting sensor 81.

  The integration posture defect detection sensor 81 is an optical sensor composed of a light emitting element 82 and a light receiving element 83, and the light emission of the light emitting element 82 is received by the light receiving element 83, whereby the integration attitude defect banknote S (S 1) is placed on the optical path. A detection operation is performed to detect that there is a stacking posture defect banknote S (S1) on the optical path because the light emission of the light emitting element 82 is blocked and the light receiving element 83 cannot receive light.

  Stacking posture so as to detect on two lines parallel to the movement direction of the banknote pressing plate 50 (stacking direction of the banknotes S) and separated from each other in the direction orthogonal to the movement direction of the banknote pressing plate 50 Two defect detection sensors 81 are provided as shown in FIG. One stacking posture defect detection sensor 81 has an optical path connecting the light emitting element 82 and the light receiving element 83 parallel to the moving direction of the banknote pressing plate 50 and slightly inside one end of the lower edge of the banknote S properly stacked. The other stacking posture defect detection sensor 81 has a light path connecting the light emitting element 82 and the light receiving element 83 parallel to the moving direction of the banknote pressing plate 50 and is properly stacked. It is provided so as to pass through a lower position slightly inside the other end of the lower edge of the bill S. These stacking posture defect detection sensors 81 are arranged so that their optical paths are located in the same plane parallel to the banknote stacking plate 12.

  It should be noted that the feeding roller 56, the rotation shaft 57, the separation roller 58, and the support shaft 59 have at least one of the axial position and the height direction position so as not to interfere with the optical path of the accumulation posture defect detection sensor 81. They are arranged differently from the optical path of the detection sensor 81. Further, in order not to interfere with the optical path of these integration posture defect detection sensors 81, the support part 39 is also arranged with at least one of the axial position and the height direction position different from the optical path of the integration posture defect detection sensor 81. ing. Here, the number of stacking posture defect detection sensors 81 may be at least two, which are on two lines parallel to the movement direction of the banknote pressing plate 50 and perpendicular to the movement direction of the banknote pressing plate 50. Three or more lines may be provided so as to detect the separated lines. In that case, it is preferable to arrange | position in the same plane parallel to the banknote stacking board 12, like the case where two are provided.

  As shown in FIG. 3, the deposit detection sensor 21, the shutter drive unit 26, the shutter open position detection sensor 27, the shutter closed position detection sensor 28, the integrated plate drive unit 40, the normal position detection sensor 41, and the retracted position detection sensor 42 described above. The pressing plate driving unit 51, the standby position sensor 52, the separation / feeding driving unit 67, the kicking position detection sensor 76, the clamping position detection sensor 77, and the two stacked posture defect detection sensors 81 communicate with the control unit (retracting means) 90. Connected as possible. Connected to the control unit 90 are an operation unit 91 for performing operation input by an operator and a display unit 92 for displaying to the operator.

  In the banknote separating and feeding mechanism 11 of the first embodiment configured as described above, the banknote stacking plate 12 is in the normal position as shown in FIG. 1 (a), and the banknote is as shown by a two-dot chain line in FIG. 1 (a). From the state where the pressing plate 50 is in the standby position away from the bill holding plate 70, the deposit slot shutter 25 is opened, and the bill S is between the bill pressing plate 50 and the bill holding plate 70 of the deposit slot 20. The banknote S is inserted in a state in which the stacking direction is directed to the direction connecting the pressing plate 50 and the banknote holding plate 70, and the inserted banknote S is placed on the banknote stacking board 12 in the above posture. Note that the banknote pressing plate 50 is manually slidable and is manually slid to a position where the banknotes S on the banknote stacking plate 12 do not fall down.

  Then, when an execution command for deposit processing is input to the operation unit 91, the control unit 90 performs the shutter driving unit on the condition that the deposit detection sensor 21 detects that the banknote S is present in the deposit port 20. 26 is driven to close the deposit port shutter 25, and when the shutter closing position detection sensor 28 detects that the deposit port shutter 25 has moved to the closed position, the shutter drive unit 26 is stopped to stop the deposit port shutter. 25 is stopped, and the bill pressing plate 50 is moved in the direction of the bill holding plate 70 by the pressing plate driving unit 51 (that is, the pressing plate driving unit 51 moves the bill pressing plate 50 based on the closing operation of the deposit port shutter 25). Control the moving position).

  By the movement described above, the banknote pressing plate 50 presses the kicking roller 62 via the banknotes S stacked on the banknote stacking plate 12, and the kicking roller 62 is moved by the swing arm 60 to the feeding roller 56. It swings around the rotation shaft 57. Then, as shown in FIG. 1B, when the detected portion 75 of the swing arm 60 is detected by the holding position detection sensor 77, the control unit 90 stops the pressing plate driving unit 51 and presses the bill. The plate 50 is stopped (that is, the pressing plate driving unit 51 controls the movement position of the banknote pressing plate 50 based on the detection result of the holding position detection sensor 77). As a result, the banknote S on the banknote stacking plate 12 is transferred to the banknote holding plate 70 and the banknote pressing plate by the urging force of the kicking spring 65 in the clamping compression state and the urging force of the clamping spring 66 in the clamping compression state. 50 with a predetermined clamping force.

  As described above, the control unit 90 is configured such that the banknotes S stacked on the banknote stacking plate 12 are sandwiched between the banknote holding plate 70 including the kick roller 62 and the banknote pressing plate 50 by the pressing plate driving unit 51. Then, the stacking plate driving unit 40 is driven to retract the banknote stacking plate 12 in the normal position downward. When the banknote stacking plate 12 is detected by the retracted position detection sensor 42, the stacking plate driving unit 40 is operated. As a result, the banknote stacking plate 12 is stopped at the retracted position. That is, the pressing plate driving unit 51 drives the support unit 39 so as to move the banknote stacking plate 12 between the normal position and the retracted position based on the detection result of the sandwiching position detection sensor 77.

  In this state, the control unit 90 performs a detection operation of causing the light emitting elements 82 of the two integrated posture defect detection sensors 81 to emit light and detecting whether or not the light receiving element 83 receives each light emission. Then, the control unit 90 is in a state where the light receiving element 83 does not receive light in at least one of the two integrated posture defect detection sensors 81, that is, on the optical path (line) of at least one of the two integrated posture defect detection sensors 81. When it is detected that the protruding portion Sa of the banknote S, that is, the downward protrusion of the banknote S is detected, it is determined that the stacking posture is defective.

  If it is determined that there is an accumulation posture failure, the control unit 90 indicates that the accumulation posture failure has occurred on the display unit 92 and prompts the banknote S to be re-inserted into the deposit port 20 so as to eliminate the accumulation posture failure. And the stacking plate driving unit 40 is driven to raise the banknote stacking plate 12 in the retracted position toward the normal position, and the banknote stacking plate 12 is detected by the normal position detection sensor 41. Then, the stacking plate driving unit 40 is stopped, and the banknote stacking plate 12 is stopped. At this time, the banknote S on the banknote stacking plate 12 is not delivered from the outlet 72 to a banknote conveyance path (not shown).

  Next, the control unit 90 drives the pressing plate driving unit 51 to move the banknote pressing plate 50 toward the standby position in a direction away from the banknote holding plate 70, and the banknote pressing plate 50 is detected by the standby position sensor 52. Then, the pressing plate driving unit 51 is stopped, and as a result, the bill pressing plate 50 is stopped at the standby position, and the shutter driving unit 26 is driven to open the deposit slot shutter 25. When the shutter opening position detection sensor 27 detects that the deposit port shutter 25 has moved to the open position, the shutter drive unit 26 is stopped, and as a result, the deposit port shutter 25 is stopped at the open position. Thereby, the banknote S on the banknote stacking plate 12 can be taken out and reinserted. Since the pressing force is released by the movement of the bill pressing plate 50 in the direction away from the bill holding plate 70, the swing arm 60 holds the kick roller 62 by the urging force of the pinching spring 66 and the kick spring 65. When the kick roller 62 protrudes from the holding plate body 13 to a predetermined position and returns to the standby position, the swing arm 60 comes into contact with a stopper (not shown) and stops. .

  On the other hand, the control unit 90 is in a state where the light receiving element 83 receives light in all of the two stacked posture defect detection sensors 81, that is, below the banknotes S on all optical paths (lines) of the two stacked posture defect detection sensors 81. When no protrusion is detected, it is determined that there is no stacking posture defect.

  When it is determined that the stacking posture defect has not occurred, the control unit 90 drives the stacking plate driving unit 40 to raise the banknote stacking plate 12 in the retracted position toward the normal position. When the banknote stacking plate 12 is detected at 41, the stacking plate driving unit 40 is stopped, and as a result, the banknote stacking plate 12 is stopped at the normal position. Next, the control part 90 will drive the press plate drive part 51, and will move the banknote press board 50 in the direction away from the banknote holding board 70, and, thereby, the press force of the banknote press board 50 is cancelled | released. Therefore, the kick roller 62 swings around the rotation shaft 57 of the feeding roller 56 by the swing arm 60 by the urging force of the clamping spring 66 and the kick spring 65. The detected portion 75 is detected by the kicking position detection sensor 76 before the swing arm 60 contacts the stopper (not shown), and the detected portion 75 is detected by the kicking position detection sensor 76. Then, the control part 90 stops the press plate drive part 51, and stops the banknote press board 50. FIG. As a result, the kicking roller 62 comes into contact with the banknote S placed on the banknote stacking plate 12 with an optimum pressure for kicking out.

  Then, the control unit 90 drives the separation / feeding driving unit 67 to drive the kicking roller 62 and the feeding roller 56 of the banknote separation / feeding unit 55, and the kicking roller 62 is in the banknote S on the banknote holding plate 70 side. The banknote S from which the feeding roller 56 and the separation roller 58 are kicked out is separated one by one and fed out from the feeding outlet 72 to a banknote conveyance path (not shown). When the amount of bills in the deposit slot 20 decreases with the feeding of the bill S, the kick roller 62 protrudes into the deposit slot 20 while swinging the swing arm 60. When the detection unit 75 is no longer detected by the kick position detection sensor 76, the control unit 90 drives the pressing plate driving unit 51 to move the bill pressing plate 50 in the direction of the bill holding plate 70 and the detected portion 75 detects the kicking position. It will be moved until it is detected by the sensor 76, and the banknote S is always brought into contact with the kicking roller 62 with an appropriate pressure by repeating this as appropriate. When the deposit detection sensor 21 detects that all the banknotes S on the banknote stacking plate 12 have been fed out to a banknote conveyance path (not shown), the control unit 90 stops the separation / feeding drive section 67 and kicks the roller. 62 and the feeding roller 56 are stopped. Thereafter, the control unit 90 drives the pressing plate driving unit 51 to move the banknote pressing plate 50 toward the standby position. When the banknote pressing plate 50 is detected by the standby position sensor 52, the control unit 90 moves the pressing plate driving unit 51. As a result, the banknote pressing plate 50 is stopped at the standby position.

  According to the banknote separating and feeding mechanism 11 of the first embodiment described above, the control unit 90 uses the pressing plate driving unit 51 to transfer the banknotes S stacked in the lateral position on the banknote stacking plate 12. When the banknote stacking plate 12 is retracted downward by the stacking plate driving unit 40 in a state of being sandwiched between the pressing plate 50 and the banknote holding plate 70, the lower part of the stacked banknotes S is below the other banknotes S. When there is a stacking posture defect banknote S (S1) that has been submerged, the support by the banknote stacking plate 12 at the bottom of the banknote S is released, and the lower part of the banknote projects downward due to its own weight and waist (inertia). Thus, the protruding portion Sa is formed. Then, the stacking posture defect detection sensor 81 detects the presence or absence of the stacking posture defect of the bill S from the presence or absence of the protruding portion Sa of the bill S sandwiched between the bill pressing plate 50 and the bill holding plate 70. Will do. Therefore, when there is a stacking posture defect banknote S (S1) in which the lower part has entered under the other banknotes S in the stacked banknotes S, for example, in the lower part near the corner of the appropriate banknote S. It is possible to detect the relatively various defect forms such as diving, and it is possible to prevent double feeding due to the separation failure of the banknote S in advance.

  Moreover, since the clamping position detection sensor 77 which detects the clamping force with respect to the banknote S of the banknote press plate 50 and the banknote holding plate 70 is provided, when retracting the banknote stacking board 12, the banknote S is securely transferred to the banknote. The sheet can be retracted while being sandwiched between the pressing plate 50 and the banknote holding plate 70.

  Further, when the banknote pressing plate 50 is pressed toward the banknote holding plate 70 so as to hold the banknote S, it can contact the banknote S closest to the banknote holding board 70 and is attached to the banknote pressing plate 50 side by the kick spring 65. The biased swingable kicking roller 62 swings against the biasing force of the kicking spring 65 and the clamping spring 66, and the kicking roller 62 swings to a predetermined clamping swinging position. When the nipping position detection sensor 77 detects this, it is detected that the banknote S is nipped with a predetermined nipping force by the kick roller 62 and the banknote pressing plate 50 constituting a part of the banknote holding plate 70. Thereby, when the banknote S is clamped by the kick roller 62 biased by the kick spring 65 and the clamping spring 66 and the banknote pressing plate 50, the clamping force for the banknote S can be detected with a simple configuration. .

  Moreover, since the control part 90 and the press board drive part 51 control the movement position of the banknote press board 50 based on the detection result of the clamping position detection sensor 77, the banknote press board 50 is moved so that it may become optimal clamping force. be able to.

  Further, the control unit 90 drives the support unit 39 with the stacking plate driving unit 40, so that the banknote stacking plate 12 is moved between a normal position close to the banknote holding plate 70 and a retracted position below the normal position. Therefore, the banknote stacking plate 12 can be moved with a simple structure.

  Further, when the support unit 39 is driven by the stacking plate driving unit 40, the parallel link mechanism 32 connected to the base portion 33 fixed to the machine body moves the banknote stacking plate 12, so that the banknote stacking plate has a simpler structure. 12 can be moved.

  Further, since the control unit 90 and the stacking plate driving unit 40 drive the support unit 39 so as to move the banknote stacking plate 12 between the normal position and the retracted position based on the detection result of the holding position detection sensor 77, the banknote When retracting the stacking plate 12 downward, the banknote stacking plate 12 can be retracted downward in a state where the banknote S is securely held between the banknote pressing plate 50 and the banknote holding plate 70.

  Further, the stacking posture defect detection sensor 81 detects two lines parallel to the movement direction of the banknote pressing plate 50 and separated from each other in a direction orthogonal to the movement direction of the banknote pressing plate 50, and at least When it is detected that the banknote S protrudes downward on any one of the lines, it is possible to appropriately detect the presence / absence of the stacking posture defect because it is determined that the stacking posture defect has occurred.

  Moreover, since the control part 90 and the press plate drive part 51 control the movement position of the banknote press board 50 based on the closing operation of the deposit slot shutter 25, the movement in the state which closed the deposit slot shutter 25 is attained, and movement It is possible to prevent a jam or the like due to the bill S being inserted therein.

  The banknote separating and feeding mechanism of the banknote handling machine according to the second embodiment of the present invention will be described below with reference mainly to FIG. 4 with a focus on differences from the first embodiment.

  The banknote separating and feeding mechanism 11 according to the second embodiment, for example, has a smaller amount of banknotes that can be inserted into the deposit port 20 at a time, that is, the capacity of the deposit port 20 is smaller than that of the first embodiment, and kicks out with the biasing force of the kick spring 65. It is suitable when the maximum amount of banknotes S within the capacity range of the deposit port 20 can be sandwiched between the roller 62 and the banknote pressing plate 50.

  In the second embodiment, the clamping spring 66 is not provided. As in the first embodiment, the kicking position detection sensor 76 detects that the kicking spring 65 is compressed by the swinging arm 60 and is compressed to a predetermined kicking compression state. Detection is performed at the position of the portion 75. On the other hand, the clamping position detection sensor 77 is configured such that the kick spring 65 is further compressed by the swing arm 60, and the maximum amount of bills within the capacity range of the deposit slot 20 is determined only by the kick roller 62 and the bill pressing plate 50. The fact that the squeezing roller 75 is in a predetermined squeezing / swinging position that generates a biasing force that enables S to be squeezed, that is, that the kick roller 62 is in a predetermined squeezing oscillating position, Detect by position.

  In the banknote separating and feeding mechanism 11 of the second embodiment having the above-described configuration, when the banknote S is inserted into the deposit port 20 and an execution command for deposit processing is input to the operation unit 91, the control unit 90 is configured as the first embodiment. In the same manner as described above, the deposit port shutter 25 is moved to the closed position to be stopped, and the bill pressing plate 50 is moved in the direction of the bill holding plate 70 by the pressing plate driving unit 51.

  By the movement described above, the banknote pressing plate 50 presses the kicking roller 62 via the banknotes S stacked on the banknote stacking plate 12 and swings the kicking roller 62 supported by the swing arm 60. Thus, as shown in FIG. 4B, when the detected portion 75 of the swing arm 60 is detected by the holding position detection sensor 77, the control unit 90 stops the bill pressing plate 50. Thereby, the banknote S on the banknote stacking plate 12 is clamped between the banknote holding plate 70 and the banknote pressing plate 50 with a predetermined clamping force by the urging force of the kick spring 65 in the clamping compression state.

  As described above, in the state where the banknotes S stacked on the banknote stacking plate 12 are sandwiched between the banknote holding plate 70 including the kick roller 62 and the banknote pressing plate 50, the control unit 90 is the same as the first embodiment. Similarly, the banknote stacking plate 12 in the normal position is retracted downward as shown in FIG. 4 (b), and both the two stacking posture defect detection sensors 81 are simultaneously operated to detect two stacking posture defects. When it is detected that the bill S protrudes downward on at least one of the optical paths (lines) of the sensor 81, it is determined that a defective stacking posture has occurred.

  If it is determined that there is a stacking posture failure, the control unit 90 notifies the deposit port 20 of the banknote S that the stacking posture failure has occurred on the display unit 92 and that the stacking posture failure is eliminated, as in the first embodiment. The banknote stacking plate 12 that has been in the retracted position is raised to the normal position, and then the banknote pressing plate 50 is moved to the standby position to open the deposit slot shutter 25. The banknote S on the banknote stacking plate 12 can be taken out and reinserted. At this time, since the pressing force of the banknote pressing plate 50 is released, the swing arm 60 returns the kicking roller 62 to the standby position by the biasing force of the kicking spring 65.

  On the other hand, when the control unit 90 detects that the bill S does not protrude downward on all the optical paths (lines) of the two stacked posture defect detection sensors 81, the controller 90 determines whether or not a stacking posture defect has occurred. As in the first embodiment, after the banknote stacking plate 12 in the retracted position is returned to the normal position, the banknote pressing plate 50 is moved away from the banknote holding plate 70. Then, the kick roller 62 is swung by the swing arm 60 by the urging force of the kick spring 65, and the controller 90 detects that the detected portion 75 is in the kick position as shown in FIG. When detected by the detection sensor 76, the bill pressing plate 50 is stopped. As a result, the kicking roller 62 comes into contact with the banknote S placed on the banknote stacking plate 12 with an optimum pressure for kicking out. And the control part 90 will separate the banknote S of the deposit port 20 one by one by the banknote isolation | separation delivery part 55 similarly to 1st Embodiment, and will deliver it to the banknote conveyance path of illustration not shown from the delivery port 72. FIG. .

  According to the banknote separating and feeding mechanism 11 of the second embodiment described above, when the banknote pressing plate 50 is pressed against the banknote holding plate 70 so as to hold the banknote S, it contacts the banknote S closest to the banknote holding plate 70. The swingable kicking roller 62 that is capable of being biased toward the bill pressing plate 50 by the kicking spring 65 swings against the biasing force of the kicking spring 65, and the kicking roller 65 When the holding position detection sensor 77 detects that the 62 has swung to a predetermined holding and swinging position, the banknote S is held between the kick roller 62 and the banknote pressing plate 50 constituting a part of the banknote holding plate 70. Detects pinching with force. Thereby, the capacity of the deposit slot 20 is small, and the maximum amount of bills S within the capacity range of the deposit slot 20 can be held between the kick roller 62 and the bill pressing plate 50 urged by the kick spring 65. In this case, it is possible to detect and control the clamping force for the bill S with a simple configuration.

  The banknote separating and feeding mechanism of the banknote handling machine according to the third embodiment of the present invention will be described below with reference mainly to FIG. 5 with a focus on differences from the second embodiment.

  The banknote separating and feeding mechanism 11 of the third embodiment has, for example, the amount of banknotes that can be inserted into the deposit port 20 at a time, that is, the capacity of the deposit port 20 is smaller than that of the second embodiment, and the kick spring 65 is in the compressed compression state. This is suitable when the maximum amount of banknotes S within the capacity range of the deposit slot 20 can be held between the kick roller 62 and the banknote pressing plate 50 with the urging force. In the third embodiment, the clamping position detection sensor 77 is also not provided.

  In the banknote separating and feeding mechanism 11 according to the third embodiment having the above-described configuration, when the banknote S is inserted into the deposit port 20 and an execution command for deposit processing is input to the operation unit 91, the control unit 90 is configured as the first embodiment. In the same manner as described above, the deposit port shutter 25 is moved to the closed position to be stopped, and the bill pressing plate 50 is moved in the direction of the bill holding plate 70 by the pressing plate driving unit 51.

  By the movement described above, the banknote pressing plate 50 presses the kicking roller 62 via the banknotes S stacked on the banknote stacking plate 12 and swings the kicking roller 62 supported by the swing arm 60. As shown in FIG. 5A, when the detected portion 75 of the swing arm 60 is detected by the kicking position detection sensor (clamping force detection means, position detection sensor) 76, the control unit 90 The bill pressing plate 50 is stopped. Thereby, the banknote S on the banknote stacking plate 12 is clamped between the banknote holding plate 70 and the banknote pressing plate 50 with a predetermined clamping force by the urging force of the kicking spring 65 in the kicking compressed state and in the sandwiching compressed state. Will be.

  As described above, in the state where the banknotes S stacked on the banknote stacking plate 12 are sandwiched between the banknote holding plate 70 including the kick roller 62 and the banknote pressing plate 50, the control unit 90 is the same as the first embodiment. Similarly, as shown in FIG. 5 (b), the banknote stacking plate 12 in the normal position is retracted downward, and both of the two stacking posture defect detection sensors 81 perform the detection operation at the same time. When it is detected that the banknote S protrudes downward on at least one of the optical paths (lines) of the detection sensor 81, it is determined that a stacking posture defect has occurred.

  If it is determined that there is a stacking posture failure, the control unit 90 notifies the deposit port 20 of the banknote S that the stacking posture failure has occurred on the display unit 92 and that the stacking posture failure is eliminated, as in the first embodiment. The banknote stacking plate 12 that has been in the retracted position is raised to the normal position, and then the banknote pressing plate 50 is moved to the standby position to open the deposit slot shutter 25. The banknote S on the banknote stacking plate 12 can be taken out and reinserted. At this time, since the pressing force of the banknote pressing plate 50 is released, the swing arm 60 returns the kicking roller 62 to the standby position by the biasing force of the kicking spring 65.

  On the other hand, when the control unit 90 detects that the bill S does not protrude downward on all the optical paths (lines) of the two stacked posture defect detection sensors 81, the controller 90 determines whether or not a stacking posture defect has occurred. Similarly to the first embodiment, after the banknote stacking plate 12 that has been in the retracted position is returned to the normal position, the banknote pressing plate 50 is left as it is, as in the first embodiment, by the banknote separating and feeding unit 55, and the deposit port 20. The banknotes S are separated one by one and fed out from the feed outlet 72 to a banknote conveyance path (not shown).

  According to the banknote separating and feeding mechanism 11 of the third embodiment described above, when the banknote pressing plate 50 is pressed against the banknote holding plate 70 so as to hold the banknote S, it contacts the banknote S closest to the banknote holding board 70. The swingable kicking roller 62 that is capable of being biased toward the bill pressing plate 50 by the kicking spring 65 swings against the biasing force of the kicking spring 65, and the kicking roller 65 When the kicking position detection sensor 76 detects that the 62 has swung to a predetermined kicking swing position, the banknote S is predetermined by the kick roller 62 and the banknote pressing plate 50 constituting a part of the banknote holding plate 70. Detecting pinching with the pinching force of. Thereby, the capacity of the deposit slot 20 is small, and the maximum amount within the capacity range of the deposit slot 20 can be obtained by the kick roller 62 and the bill pressing plate 50 urged by the kick spring 65 in the kick compression state. When the banknote S can be clamped, it is possible to detect and control the clamping force for the banknote S with a simple configuration.

  The banknote separating / feeding mechanism of the banknote handling machine according to the fourth embodiment of the present invention will be described below with reference mainly to FIG. 6 focusing on the differences from the first embodiment.

  The banknote separating and feeding mechanism 11 of the fourth embodiment has, for example, a larger amount of banknotes that can be inserted into the depositing port 20 at the same time, that is, the capacity of the depositing port 20 than that of the first embodiment, and the kick spring 65 and the holding spring 66 are attached. The power is suitable when the maximum amount of banknotes S within the capacity range of the deposit port 20 cannot be sandwiched between the banknote holding plate 70 and the banknote pressing plate 50.

  In the banknote separating and feeding mechanism 11 of the fourth embodiment, the holding spring 66 is not provided. Further, the sandwiching position detection sensor 77 is not provided, and instead, on both the surface on the banknote pressing plate 50 side of the holding plate body 13 of the banknote holding plate 70 and the surface on the banknote holding plate 70 side of the banknote pressing plate 50. Based on the detection results of the provided pressure detection sensors (clamping force detection means) 100, 101, the clamping force of the bill pressing plate 50 and the bill holding plate 70 with respect to the bill S is detected. When the pressure of any one of the pressure detection sensors 100 and 101 reaches a predetermined clamping pressure value, the clamping force that enables clamping of the maximum amount of banknotes S within the capacity range of the deposit slot 20 is set to the banknote pressing plate 50. It is determined that the bill holding plate 70 has been generated. Note that only one of the pressure detection sensors 100 and 101 may be provided, and the clamping force of the banknote pressing plate 50 and the banknote holding plate 70 with respect to the banknote S may be detected based on the detection result of the one.

  In the banknote separating and feeding mechanism 11 of the fourth embodiment configured as described above, when the banknote S is inserted into the deposit port 20 and an execution command for deposit processing is input to the operation unit 91, the control unit 90 is the first embodiment. In the same manner as described above, the deposit port shutter 25 is moved to the closed position to be stopped, and the bill pressing plate 50 is moved in the direction of the bill holding plate 70 by the pressing plate driving unit 51.

  By the movement described above, the banknote pressing plate 50 presses the kicking roller 62 via the banknotes S stacked on the banknote stacking plate 12 and swings the kicking roller 62 supported by the swing arm 60. Thus, as shown in FIG. 6B, the kick roller 62 is pushed out and the bill S is held between the bill pressing plate 50 and the holding plate main body 13. Then, when at least one of the detected pressures reaches a predetermined clamping pressure value from the detection results of the pressure detection sensors 100 and 101, the control unit 90 stops the bill pressing plate 50. Thereby, the banknote S on the banknote stacking plate 12 is held between the holding plate body 13 of the banknote holding plate 70 and the banknote pressing plate 50 with a predetermined holding force.

  As described above, the control unit 90 is the same as in the first embodiment in a state where the banknotes S stacked on the banknote stacking plate 12 are sandwiched between the holding plate body 13 of the banknote holding plate 70 and the banknote pressing plate 50. As shown in FIG. 6B, the banknote stacking plate 12 in the normal position is retracted downward, and both the two stacking posture defect detection sensors 81 perform the detection operation at the same time. When it is detected that the banknote S protrudes downward on at least one of the optical paths (lines) 81, it is determined that a defective stacking posture has occurred.

  If it is determined that there is a stacking posture failure, the control unit 90 notifies the deposit port 20 of the banknote S that the stacking posture failure has occurred on the display unit 92 and that the stacking posture failure is eliminated, as in the first embodiment. The banknote stacking plate 12 that has been in the retracted position is raised to the normal position, and then the banknote pressing plate 50 is moved to the standby position to open the deposit slot shutter 25. The banknote S on the banknote stacking plate 12 can be taken out and reinserted. At this time, since the pressing force of the banknote pressing plate 50 is released, the swing arm 60 returns the kicking roller 62 to the standby position by the biasing force of the kicking spring 65.

  On the other hand, when the control unit 90 detects that the bill S does not protrude downward on all the optical paths (lines) of the two stacked posture defect detection sensors 81, the controller 90 determines whether or not a stacking posture defect has occurred. As in the first embodiment, after the banknote stacking plate 12 in the retracted position is returned to the normal position, the banknote pressing plate 50 is moved away from the banknote holding plate 70. Then, the kick roller 62 is swung by the swing arm 60 by the urging force of the kick spring 65, and the control unit 90 detects the kick position as shown in FIG. When detected by the sensor 76, the bill pressing plate 50 is stopped. As a result, the kicking roller 62 comes into contact with the banknote S placed on the banknote stacking plate 12 with an optimum pressure for kicking out. And the control part 90 will separate the banknote S of the deposit port 20 one by one by the banknote isolation | separation delivery part 55 similarly to 1st Embodiment, and will deliver it to the banknote conveyance path of illustration not shown from the delivery port 72. FIG. .

  According to the banknote separating and feeding mechanism 11 of the fourth embodiment described above, both the surface on the banknote pressing plate 50 side of the holding plate body 13 of the banknote holding plate 70 and the surface on the banknote holding plate 70 side of the banknote pressing plate 50. Since the clamping force with respect to the banknote S of the banknote pressing plate 50 and the banknote holding plate 70 is detected based on the detection results of the pressure detection sensors 100 and 101 provided on the banknote pressing plate 50, the banknote pressing plate 50 moves the kick roller 62. When the banknote S is clamped between the banknote holding plate 70 in the pressed state, the clamping force for the banknote S can be detected and controlled with a simple configuration.

  The banknote separating and feeding mechanism of the banknote handling machine according to the fifth embodiment of the present invention will be described below with reference mainly to FIGS. 7 and 8 mainly focusing on the differences from the first embodiment.

Mounting portions 31 projecting upward in the vertical direction from the edge portion are integrally formed, and each of these mounting portions 31 is provided on a base portion 33 provided in a fixed position on the machine body via a parallel link mechanism 32. It is connected. Therefore, the convex plate portion 110 and the pair of movable plate portions 111 and 112 are supported by the support portion 39 and can be moved up and down. In this case as well, the attachment portion 31 can be protruded downward from the banknote stacking plate 12.

  In 5th Embodiment, the figure which drives the support part 39 connected with each of the above-mentioned convex-shaped board part 110 and a pair of movable board parts 111 and 112 separately, and the convex-shaped board part 110 is driven. 8, the movable plate portion drive unit (drive unit) 118 shown in FIG. 8 that drives the support unit 39 connected to one movable plate unit 111, and the other plate plate drive unit (drive unit) 117 shown in FIG. 8 that detects the position of the movable plate part drive unit (drive unit) 119 shown in FIG. 8 that drives the support unit 39 connected to the movable plate part 112 and the convex plate part 110 in the normal position. The position detection sensor 121, the retraction position detection sensor 122 shown in FIG. 8 for detecting that the convex plate portion 110 is located at the retraction position, and the detection of that one movable plate portion 111 is located at the normal position. Normal position detection sensor 123 shown in FIG. 8, the retracted position detection sensor 124 shown in FIG. 8 for detecting that one movable plate portion 111 is located at the retracted position, and the normal position shown in FIG. 8 for detecting that the other movable plate portion 112 is located at the normal position. The detection sensor 125 and the retraction position detection sensor 126 shown in FIG. 8 that detects that the other movable plate portion 112 is located at the retraction position constitute a retraction portion (retraction means) 43.

  In the banknote separating and feeding mechanism 11 of the fifth embodiment configured as described above, when the banknote S is inserted into the deposit port 20 and an execution command for deposit processing is input to the operation unit 91, the control unit 90 is configured as the first embodiment. In the same manner as described above, the deposit port shutter 25 is moved to the closed position to be stopped, the bill pressing plate 50 is moved in the direction of the bill holding plate 70 by the pressing plate driving unit 51, and the detected portion 75 of the swing arm 60 is When detected by the nipping position detection sensor 77, the control unit 90 stops the bill pressing plate 50. Thereby, the banknote S on the banknote stacking plate 12 is clamped between the banknote holding plate 70 and the banknote pressing plate 50 with a predetermined clamping force by the urging force of the kicking spring 65 and the clamping spring 66 in the clamping compression state. It will be.

  As described above, the control unit 90 is configured such that the banknotes S stacked on the banknote stacking plate 12 are sandwiched between the banknote holding plate 70 including the kick roller 62 and the banknote pressing plate 50 by the pressing plate driving unit 51. Then, the convex plate portion driving unit 117 and the movable plate portion driving unit 119 are driven to retract the convex plate portion 110 and the other movable plate portion 112 of the banknote stacking plate 12 at the normal position downward. If the convex plate portion 110 is detected by the retreat position detection sensor 122, the convex plate portion drive section 117 is stopped, and if the other movable plate portion 112 is detected by the retraction position detection sensor 126, the movable plate portion is movable. The plate part drive part 119 is stopped. As a result, as shown in FIG. 7 (b), one of the banknote stacking plates 12 is placed in the normal position and the banknote S is left on the convex plate section 110. Then, the first movable state in which the other movable plate portion 112 is positioned at the retracted position is set. That is, the first retracted state in which the convex plate portion 110 and the other of the pair of movable plate portions 111 and 112 are retracted downward while one of the pair of movable plate portions 111 and 112 is stopped.

  In this state, the control unit 90 causes the light emitting element 82 to emit light only with the integrated posture defect detection sensor 81 arranged on the other movable plate portion 112 side, and detects whether the light receiving element 83 receives the light emission. Perform the detection operation. Then, the controller 90 is in a state where the light receiving element 83 does not receive light in the integrated posture defect detection sensor 81 arranged on the other movable plate portion 112 side, that is, as shown in FIG. 7B, the other movable plate portion. When it is detected that the banknote S protrudes downward on the optical path (line) of the stacking posture defect detection sensor 81 arranged on the 112 side, it is determined that a stacking posture defect has occurred.

  When it is determined from the detection result of the stacking posture defect detection sensor 81 arranged on the other movable plate portion 112 side that the stacking posture defect has occurred, the control unit 90 indicates that the stacking posture defect has occurred on the display unit 92, and In addition to displaying a message that prompts the banknote S to be reinserted into the deposit port 20 so as to eliminate the stacking posture failure, the convex plate portion drive unit 117 and the movable plate portion drive unit 119 are driven to the retracted position. The raised convex plate portion 110 and the other movable plate portion 112 are raised toward the normal position. When the convex plate portion 110 is detected by the normal position detection sensor 121, the convex plate portion driving unit 117 is stopped, and the convex plate portion 110 is stopped at the normal position. When the other movable plate portion 112 is detected, the movable plate portion driving portion 119 is stopped, and the other movable plate portion 112 is stopped at the normal position. At this time, the banknote S on the banknote stacking plate 12 is not delivered from the outlet 72 to a banknote conveyance path (not shown).

  Next, the control part 90 returns the banknote press board 50 to a standby position similarly to 1st Embodiment, and makes the deposit port shutter 25 an open state. Thereby, the banknote S on the banknote stacking plate 12 can be taken out and reinserted.

  When it is determined from the detection result of the stacking posture failure detection sensor 81 arranged on the other movable plate portion 112 side that the stacking posture failure does not occur, the control unit 90 keeps the convex plate portion 110 as it is and the movable plate. The part drive part 119 is driven, and the other movable plate part 112 in the retracted position is raised toward the normal position. When the other movable plate portion 112 is detected by the normal position detection sensor 126, the movable plate portion driving unit 119 is stopped, and the other movable plate portion 112 is stopped at the normal position. Subsequently, the control unit 90 drives the movable plate unit drive unit 118 to retreat one movable plate unit 111 located at the normal position downward, and the retraction position detection sensor 124 detects one movable plate unit. When 111 is detected, the movable plate portion drive unit 118 is stopped. As a result, in the banknote stacking plate 12, the other movable plate portion 112 is positioned at the normal position and the bill S is placed, and the convex plate portion 110 and the one movable plate portion 111 are retracted. It will be in the 2nd evacuation state located in this. In other words, the second retracted state in which one of the convex plate portion 110 and the pair of movable plate portions 111 and 112 is retracted downward while the other of the pair of movable plate portions 111 and 112 is stopped.

  In this state, the control unit 90 causes the light emitting element 82 to emit light only by the integrated posture defect detection sensor 81 arranged on the one movable plate portion 111 side, and detects whether the light receiving element 83 receives the light emission. Perform the detection operation. Then, the control unit 90 detects the state where the light receiving element 83 does not receive light in the integrated posture defect detection sensor 81 disposed on the one movable plate portion 111 side, that is, detects the integrated posture defect disposed on the one movable plate portion 111 side. When it is detected that the bill S protrudes downward on the optical path (line) of the sensor 81, it is determined that a defective stacking posture has occurred. As a result, the two stacked posture defect detection sensors 81 perform the detection operation for detecting the presence or absence of the stacked posture defect in both the first retracted state and the second retracted state.

  When it is determined from the detection result of the stacking posture defect detection sensor 81 arranged on the one movable plate portion 111 side that the stacking posture defect has occurred, the control unit 90 indicates that the stacking posture defect has occurred on the display unit 92, and A display is made to prompt the user to reinsert the bill S into the deposit slot 20 so as to eliminate the stacking posture failure, and the convex plate portion drive unit 117 and the movable plate portion drive unit 118 are driven to the retracted position. The raised convex plate portion 110 and one movable plate portion 111 are raised toward the normal position. When the convex plate portion 110 is detected by the normal position detection sensor 121, the convex plate portion driving unit 117 is stopped, and the convex plate portion 110 is stopped at the normal position, so that the normal position detection sensor 123 is stopped. When one of the movable plate portions 111 is detected, the movable plate portion driving unit 118 is stopped, and the one movable plate portion 111 is stopped at the normal position. At this time, the banknote S on the banknote stacking plate 12 is not delivered from the outlet 72 to a banknote conveyance path (not shown).

  Next, the control part 90 returns the banknote press board 50 to a standby position similarly to the above, and makes the deposit port shutter 25 an open state. Thereby, the banknote S on the banknote stacking plate 12 can be taken out and reinserted.

  When it is determined from the detection result of the stacking posture defect detection sensor 81 arranged on the one movable plate portion 111 side that the occurrence of the stacking posture defect has not occurred, the control unit 90 causes the convex plate unit driving unit 117 and the movable plate unit driving unit. 118 is driven to raise the convex plate portion 110 and one movable plate portion 111 in the retracted position toward the normal position. When the convex plate portion 110 is detected by the normal position detection sensor 121, the convex plate portion driving unit 117 is stopped, and the convex plate portion 110 is stopped at the normal position, so that the normal position detection sensor 123 is stopped. When one of the movable plate portions 111 is detected, the movable plate portion driving unit 118 is stopped, and the one movable plate portion 111 is stopped at the normal position.

  As described above, when it is determined from the detection results of both of the two stacked posture failure detection sensors 81 that the stacked posture failure has not occurred, the control unit 90 moves the banknote pressing plate 50 to the banknote holding plate 70 as in the first embodiment. When the detected portion 75 is detected by the kicking position detection sensor 76, it is stopped. As a result, the kicking roller 62 comes into contact with the banknote S placed on the banknote stacking plate 12 with an optimum pressure for kicking out. And the control part 90 will separate the banknote S of the deposit port 20 one by one by the banknote isolation | separation delivery part 55 similarly to 1st Embodiment, and will deliver it to the banknote conveyance path of illustration not shown from the delivery port 72. FIG. .

  According to the banknote separating and feeding mechanism 11 of the fifth embodiment described above, the retracting portion 43 supports the banknote S in one of the pair of movable plate portions 111 and 112 and the pair of convex plate portions 110 and the pair. As the first retracted state in which the other of the movable plate portions 111 and 112 is retracted downward, the stacking posture defect detection sensor 81 on the other side of the pair of movable plate portions 111 and 112 determines whether or not there is a stacking posture defect. One of the convex plate portion 110 and the pair of movable plate portions 111 and 112 is performed in a state where the bill S is supported by the other of the pair of movable plate portions 111 and 112. As the second retreat state in which the retraction is performed downward, the accumulation posture defect detection sensor 81 on one side of the pair of movable plate portions 111 and 112 performs a detection operation for detecting the presence or absence of the accumulation posture defect. For this reason, the detection operation | movement which detects the presence or absence of a stacking attitude | position defect in the state which supported the banknote S from the downward direction in one of a pair of movable board part 111,112 can be performed. Therefore, even if the clamping force between the banknote pressing plate 50 and the banknote holding plate 70 is relatively small, the banknote S protruding downward can be detected.

  The banknote separating and feeding mechanism of the banknote handling machine according to the sixth embodiment of the present invention will be described below with reference mainly to FIG. 9 focusing on the differences from the first embodiment.

  In the banknote separating and feeding mechanism 11 of the sixth embodiment, the banknote stacking plate 12 includes a concave plate portion 130 that can be moved up and down, and a fixed plate portion 131 that is provided at a fixed position on the machine body. The concave plate portion 130 is formed with a concave portion 133 extending in the stacking direction of the banknotes S at an intermediate portion in the horizontal direction orthogonal to the stacking direction of the banknotes S on the upper surface, specifically, at the center position. The fixed plate portion 131 is arranged in the concave portion 133 of the concave plate portion 130 in the normal position.

  Although not shown in FIG. 9, the projection protruding upward in the vertical direction from the edge of the concave plate 130 on the side of the end wall plate 14 as in the banknote stacking plate 12 shown in FIG. 1 of the first embodiment. The retraction part 43 connects the attachment part 31 of the concave plate part 130 to the parallel link mechanism 32, and the parallel plate mechanism 32 is driven by the integrated plate driving part 40. Then, the concave plate portion 130 is lowered from the normal position to the lower retracted position. In addition, the retracting portion 43 detects that the normal position detection sensor 41 is located at the normal position of the concave plate portion 130, and the retracting position detection sensor 42 is positioned at the retracted position of the concave shape plate portion 130. Will be detected.

  In the banknote separating and feeding mechanism 11 of the sixth embodiment configured as described above, when the banknote S is inserted into the deposit port 20 and an execution command for deposit processing is input to the operation unit 91, the control unit 90 is the first embodiment. In the same manner as described above, the deposit port shutter 25 is moved to the closed position to be stopped, the bill pressing plate 50 is moved in the direction of the bill holding plate 70 by the pressing plate driving unit 51, and the detected portion 75 of the swing arm 60 is When detected by the nipping position detection sensor 77, the control unit 90 stops the bill pressing plate 50. Thereby, the banknote S on the banknote stacking plate 12 is clamped between the banknote holding plate 70 and the banknote pressing plate 50 with a predetermined clamping force by the urging force of the kick spring 65 in the clamping compression state.

  As described above, in a state where the banknotes S stacked on the banknote stacking plate 12 are sandwiched between the banknote holding plate 70 including the kick roller 62 and the banknote pressing plate 50, the control unit 90 is attached to the fixed plate portion 131. While the center of the banknote S is placed, the concave plate portion 130 in the normal position is retracted to the retracted position detected by the retracted position detection sensor 42 by the stacking plate driving unit 40. When both of the two stacked posture defect detection sensors 81 perform the detection operation at the same time and detect the downward protrusion of the banknote S on the optical path (line) of at least one of the two stacked posture defect detection sensors 81, the stacking is performed. It is determined whether or not a posture failure has occurred.

  If it is determined that there is a stacking posture failure, the control unit 90 notifies the deposit port 20 of the banknote S that the stacking posture failure has occurred on the display unit 92 and that the stacking posture failure is eliminated, as in the first embodiment. After the concave plate portion 130 in the retracted position is returned to the normal position detected by the normal position detection sensor 41 by the stacking plate driving portion 40, the bill is pressed. The plate 50 is moved to the standby position, the deposit port shutter 25 is opened, and the bill S on the bill stacking plate 12 can be taken out and reinserted.

  On the other hand, when the control unit 90 detects that the banknote S does not protrude downward on all the optical paths (lines) of the two stacked posture defect detection sensors 81, the controller 90 determines whether or not a stacking posture defect has occurred, and retreats. After the concave plate portion 130 at the position is returned to the normal position detected by the normal position detection sensor 41 by the stacking plate driving portion 40, the bill pressing plate 50 is moved away from the bill holding plate 70. When the detected portion 75 is detected by the kicking position detection sensor 76, the detected portion 75 is stopped. As a result, the kicking roller 62 comes into contact with the banknote S placed on the banknote stacking plate 12 with an optimum pressure for kicking out. And the control part 90 will separate the banknote S of the deposit port 20 one by one by the banknote isolation | separation delivery part 55 similarly to 1st Embodiment, and will deliver it to the banknote conveyance path of illustration not shown from the delivery port 72. FIG. .

  According to the banknote separating and feeding mechanism 11 of the sixth embodiment described above, the retracting part 43 retracts the concave plate part 130 downward while the banknote S is supported by the fixed plate part 131 fixed to the machine body. Thus, since the two stacked posture defect detection sensors 81 perform the detection operation for detecting the presence or absence of the stacked posture defect, it is possible to perform the detection operation for detecting the presence or absence of the stacked posture defect with the banknote S supported from below. . Therefore, even if the clamping force between the banknote pressing plate 50 and the banknote holding plate 70 is relatively small, the banknote S protruding downward can be detected.

  The banknote separating and feeding mechanism of the banknote handling machine according to the seventh embodiment of the present invention will be described below mainly with reference to FIG.

  In the banknote separating and feeding mechanism 11 of the seventh embodiment, the banknote stacking plate 12 is positioned on the airframe on the opposite side of the banknote holding plate 70 and the movable banknote stacking plate portion 140 provided on the banknote holding plate 70 side. It is divided into a fixed banknote stacking plate portion 141 provided in a fixed manner.

  The movable banknote stacking plate 140 is integrally formed with a mounting portion 31 that protrudes downward in the vertical direction from the edge on the fixed banknote stacking plate portion 141 side. And is connected to a base portion 33 provided in a fixed position on the machine body. The retracting unit 43 lowers the movable banknote stacking plate part 140 from the normal position to the retracted position below by driving the parallel link mechanism 32 by the stacking plate driving unit 40. In addition, the retracting unit 43 detects that the normal position detection sensor 41 is located at the normal position of the movable banknote stacking plate 140, and the retracting position detection sensor 42 detects that the movable banknote stacking plate unit 140 is at the retracted position. Will be detected. Here, the length in the stacking direction of the banknotes S (moving direction of the banknote pressing plate 50) of the movable banknote stacking plate portion 140 is at least 1/4 or more and not more than the height of the standing banknote S. Is set. Although not shown, the fixed banknote stacking plate portion 141 is formed with holes for forming the optical paths of the two stacking posture failure detection sensors 81 along the stacking direction of the banknotes S.

  In the banknote separating and feeding mechanism 11 according to the seventh embodiment having the above-described configuration, when the banknote S is inserted into the deposit port 20 and an execution command for deposit processing is input to the operation unit 91, the control unit 90 is the first embodiment. In the same manner as described above, the deposit port shutter 25 is moved to the closed position to be stopped, and the bill pressing plate 50 is moved in the direction of the bill holding plate 70 by the pressing plate driving unit 51.

  By the movement described above, the banknote pressing plate 50 presses the kicking roller 62 via the banknotes S stacked on the banknote stacking plate 12 and swings the kicking roller 62 supported by the swing arm 60. Thus, when the detected portion 75 of the swing arm 60 is detected by the holding position detection sensor 77, the control unit 90 stops the bill pressing plate 50. Thereby, the banknote S on the banknote stacking plate 12 is clamped between the banknote holding plate 70 and the banknote pressing plate 50 with a predetermined clamping force by the urging force of the kicking spring 65 and the clamping spring 66 in the clamping compression state. It will be.

  As described above, in a state where the banknotes S stacked on the banknote stacking plate 12 are sandwiched between the banknote holding plate 70 including the kick roller 62 and the banknote pressing plate 50, the control unit 90 is a fixed banknote stacking plate unit. 141, the banknote S on the end wall plate 14 side is placed on the movable banknote stacking plate portion 140 in the normal position with the stacking plate driving unit 40 retracted to the retracted position detected by the retracting position detection sensor 42. In this state, both of the two stacked posture defect detection sensors 81 perform detection operations simultaneously, and the bills S are moved downward on at least one of the optical paths (lines) of the two stacked posture defect detection sensors 81. When it is detected that there is a protrusion, it is determined that there is an accumulation posture defect.

  If it is determined that there is a stacking posture failure, the control unit 90 notifies the deposit port 20 of the banknote S that the stacking posture failure has occurred on the display unit 92 and that the stacking posture failure is eliminated, as in the first embodiment. Is displayed, and the movable banknote stacking plate portion 140 that has been in the retracted position is returned to the normal position detected by the normal position detection sensor 41 by the stacking plate driving section 40, and then the banknote The pressing plate 50 is moved to the standby position, the deposit slot shutter 25 is opened, and the bill S on the bill stacking plate 12 can be taken out and reinserted.

  On the other hand, when the control unit 90 detects that the banknote S does not protrude downward on all the optical paths (lines) of the two stacked posture defect detection sensors 81, the controller 90 determines whether or not a stacking posture defect has occurred, and retreats. After the movable banknote stacking plate portion 140 at the position is returned to the normal position detected by the normal position detecting sensor 41 by the stacking plate driving section 40, the banknote pressing plate 50 is moved in a direction away from the banknote holding plate 70. Let Then, the kick roller 62 is swung by the swing arm 60 by the urging force of the kick spring 65 and the holding spring 66, and the controller 90 detects the detected portion 75 by the kick position detection sensor 76. Then, the banknote pressing plate 50 is stopped. As a result, the kicking roller 62 comes into contact with the banknote S placed on the banknote stacking plate 12 with an optimum pressure for kicking out. And the control part 90 will separate the banknote S of the deposit port 20 one by one by the banknote isolation | separation delivery part 55 similarly to 1st Embodiment, and will deliver it to the banknote conveyance path of illustration not shown from the delivery port 72. FIG. .

  Next, when a predetermined number of banknotes S are fed out from the deposit slot 20, the control unit 90 stops the banknote separating and feeding unit 55 and moves the banknote pressing plate 50 toward the banknote holding plate 70 by the pressing plate driving unit 51. Let The predetermined number is set to a number equal to or less than the amount of banknotes that can be arranged on the movable banknote stacking plate portion 140. In other words, the stacking direction of the banknotes S (movement of the banknote pressing plate 50) of the movable banknote stacking plate portion 140 is set. Set in accordance with the length in the direction).

  And if the to-be-detected part 75 of the rocking | fluctuating arm 60 is detected by the clamping position detection sensor 77, the control part 90 will stop the banknote press board 50. FIG. Thereby, the banknote S on the banknote stacking plate 12 is clamped between the banknote holding plate 70 and the banknote pressing plate 50 with a predetermined clamping force by the urging force of the kicking spring 65 and the clamping spring 66 in the clamping compression state. It will be.

  As described above, in a state where the banknotes S stacked on the banknote stacking plate 12 are sandwiched between the banknote holding plate 70 including the kick roller 62 and the banknote pressing plate 50, the control unit 90 is a fixed banknote stacking plate unit. 141, the banknote S on the end wall plate 14 side is placed on the movable banknote stacking plate portion 140 in the normal position with the stacking plate driving unit 40 retracted to the retracted position detected by the retracting position detection sensor 42. In this state, both of the two stacked posture defect detection sensors 81 perform detection operations simultaneously, and the bills S are moved downward on at least one of the optical paths (lines) of the two stacked posture defect detection sensors 81. When it is detected that there is a protrusion, it is determined that there is an accumulation posture defect.

  When it is determined that there is a stacking posture failure, the control unit 90, as described above, indicates that the stacking posture failure has occurred in the display unit 92 and puts the banknote S into the deposit port 20 so as to eliminate the stacking posture failure. After displaying the message for prompting correction, the movable banknote stacking plate part 140 that has been in the retracted position is returned to the normal position detected by the normal position detection sensor 41 by the stacking board driving unit 40, and then the banknote pressing plate 50. Is moved to the standby position, the deposit port shutter 25 is opened, and the bill S on the bill stacking plate 12 can be taken out and reinserted. At this time, since the pressing force of the bill pressing plate 50 is released, the swing arm 60 returns the kicking roller 62 to the standby position by the urging force of the kicking spring 65 and the holding spring 66.

  On the other hand, when the controller 90 detects no downward protrusion of the banknote S on all the optical paths (lines) of the two stacked posture defect detection sensors 81, the controller 90 determines whether or not a stacking posture defect has occurred. In the same manner as described above, after the movable banknote stacking plate 140 in the retracted position is returned to the normal position detected by the normal position detection sensor 41 by the stacking plate driving unit 40, the banknote pressing plate 50 is separated from the banknote holding plate 70. Move in the direction you want. Then, the kick roller 62 is swung by the swing arm 60 by the urging force of the kick spring 65 and the holding spring 66, and the controller 90 detects the detected portion 75 by the kick position detection sensor 76. Then, the banknote pressing plate 50 is stopped. As a result, the kicking roller 62 comes into contact with the banknote S placed on the banknote stacking plate 12 with an optimum pressure for kicking out. And the control part 90 will separate the banknote S of the deposit port 20 one by one by the banknote isolation | separation delivery part 55 similarly to 1st Embodiment, and will deliver it to the banknote conveyance path of illustration not shown from the delivery port 72. FIG. .

  Then, the above-described detection operation for detecting whether or not there is a stacking posture defect is performed every time a predetermined number of banknotes S are fed by the banknote separating and feeding unit 55 until the banknotes S in the deposit port 20 run out.

  According to the banknote separating and feeding mechanism 11 of the seventh embodiment described above, the fixed banknote stacking plate part 141 provided on the opposite side to the banknote holding board 70 is fixed, and the retracting part 43 is used for holding the banknote. The movable banknote stacking plate part 140 that can be moved up and down provided on the plate 70 side is retracted downward, and the stacking posture defect detection sensor 81 performs a detection operation for detecting the presence or absence of a stacking posture defect. The amount of banknotes S that must be sandwiched between the banknote holding plates 70 can be substantially reduced. Therefore, even if the clamping force between the banknote pressing plate 50 and the banknote holding plate 70 is relatively small, the banknote S protruding downward can be detected. And the detection operation which detects the presence or absence of a stacking posture defect is performed for every delivery of the predetermined number of banknotes S by the banknote separating and feeding unit 55, thereby sequentially shifting the region for detecting the presence or absence of a stacking posture failure.

  Moreover, since the length in the moving direction of the banknote pressing plate 50 of the movable banknote stacking plate part 140 is at least 1/4 of the height of the banknote S in the standing position and below the height, the lower part is another banknote. It is possible to satisfactorily detect the stacking posture defect banknote S (S1) in the state of being submerged under S.

  In addition, since the predetermined number of times for performing the detection operation for detecting the presence or absence of the stacking posture defect is determined in advance according to the length of the movable banknote stacking plate part 140 in the moving direction of the banknote pressing plate 50, By performing the detection operation for detecting the presence / absence of a stacking posture defect every time a predetermined number of banknotes S are fed by the banknote separating and feeding unit 55, it is possible to appropriately detect the presence / absence of a stacking posture failure.

  In the fifth to seventh embodiments, as in the first embodiment, a case where the banknote S is sandwiched between the kick roller 62 and the banknote pressing plate 50 by the urging force of the kick spring 65 and the sandwiching spring 66 is taken as an example. However, as in the second and third embodiments, the present invention can also be applied to the case where the banknote S is sandwiched between the kick roller 62 and the banknote pressing plate 50 by the urging force of the kick spring 65, which is the fourth embodiment. Similar to the embodiment, the present invention is also applicable to the case where the bill S is sandwiched between the holding plate main body 13 and the bill pressing plate 50 by the driving force of the pressing plate driving unit 51.

  In the first to seventh embodiments, the banknote stacking plate 12 is translated from the normal position to the retracted position by the parallel link mechanism 32. However, the banknote stacking plate 12 may not be parallel, and the banknote stacking plate 12 is stacked. It is only necessary to be able to retreat to a position that does not interfere with the detection of the defect detection sensor 81.
