Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of Invention  
         [0002]     The present invention relates to a media dispenser, and more particularly, to a media dispenser wherein a customer&#39;s desired number of media are collected and delivered at a time and a method for rejecting media which the customer did not take out of the media dispenser.  
         [0003]     2. Description of the Prior Art  
         [0004]      FIG. 1  shows the constitution of a prior art media dispenser. According to the figure, various components for feeding media are provided between two guide plates  200  spaced apart by a predetermined interval from each other. A front surface of the media dispenser corresponding to an end of the guide plates  200  is provided with a door  202  for selectively opening or closing a predetermined space formed between the guide plates  200 . The door  202  is installed to the guide plates  200  to be opened or closed about a hinge. Reference numeral  204  designates a locking member for keeping the door  202  closed.  
         [0005]     In the meantime, a reject box  206  for collecting abnormal media is mounted in the space between the guide plates  200  selectively opened and closed by the door  202 . A media box  208  is mounted below a position, where the reject box  206  is mounted, in the space selectively opened and closed by the door  202 . The media to be fed from the media dispenser are put in the media box  208 . The reject box  206  and the media box  208  are detachably mounted with the door  202  being opened.  
         [0006]     Then, the guide plates  200  are provided with various components for feeding the media. First, a driving motor  210  providing a driving force for feeding the media is installed at a side of the guide plates  200 . In order to separate the media in the media box  208  and put out them one by one, a pickup roller  212  is installed at a position corresponding to a front end of the media box  208 .  
         [0007]     A feeding path  214  for feeding the media is formed between the guide plates  200  as indicated with an arrow. The feeding path  214  is composed of a plurality of rollers  216  and belts  218 . A diverter  220  for rejecting the abnormal media to the reject box  206  is provided on the feeding path  214 . In addition, a discharge part  230  is provided at an upper end of the front surface of the media dispenser, which is an end portion of the feeding path  214 . Such a media dispenser is installed in a cabinet defining an external appearance thereof for use.  
         [0008]     However, such a prior art has some problems as follows.  
         [0009]     In the prior art, when a number of sheets of the media are delivered, the media are freely dropped at a position, where the customer takes out them, and are stacked up. Thus, a number of the media are not closely stacked and become relatively large in volume, so that it is very inconvenient that the customer picks up them by hand.  
         [0010]     In addition, when the customer has not yet taken out the media, a reject box for rejecting the media should be positioned adjacent to the position where the customer takes out the media. Thus, that is also a problem since there is no way to feeding the media, which are once provided to the customer, into the media dispenser again at a time.  
         [0011]     Further, since a variety of the components of the media dispenser are provided in the guide plates  200 , there is inconvenience in that the media dispenser should be wholly disassembled in order to repair the components therein.  
         [0012]     Furthermore, in the prior art, since the media may be taken out of the media dispenser in a state when an inlet of the reject box is opened, there is a problem in that the media rejected and stored in the reject box may be stolen.  
       SUMMARY OF THE INVENTION  
       [0013]     Accordingly, the present invention is conceived to solve the aforementioned problems in the prior art. An object of the present invention is to provide a media dispenser by which a number of media can be delivered to a customer at a time and the media which the customer did not take out at a time can be rejected.  
         [0014]     Another object of the present invention is to prevent a reject box in which rejected media are stored from separating from the media dispenser while an inlet of reject box is opened.  
         [0015]     A further object of the present invention is to freely design a structure for rejecting media.  
         [0016]     According to an aspect of the present invention for achieving the objects, there is provided a media dispenser, comprising: a delivery module for feeding media, which come out of a media box, one by one; a stacking module for stacking the media, which are fed through the delivery module, on a stacking plate as many as a customer wants; and a delivery clamp module for clamping the media stacked on the stacking module and delivering the clamped media to the customer, and for feeding the media, which the customer did not take out, to the stacking plate, wherein a path through which the media clamped by the delivery clamp module are fed to a reject box is opened by moving the stacking plate of the stacking module.  
         [0017]     Preferably, the stacking module comprises: stacking wheels rotated by a driving source to rotate the media fed from the delivery module with the media inserted between tangent wings of outer peripheral surfaces of the stacking wheels one by one; a stacking base provided at a position adjacent to the stacking wheels and including a reject slot for receiving the rejected media; a separation plate extending from a front end of the stacking base between the stacking wheels to downwardly incline to the reject slot, and thus, separating the media from the stacking wheels to guide the media; the stacking plate movably installed on the stacking base to selectively open and close the reject slot, the media separated in the separation plate being erected on the stacking plate one by one; a shuttle member rotatably installed on the stacking plate and including a push bar for pushing the media erected on the stacking plate toward the stacking wheels; and a driving plate driven by an additional driving source to selectively drive the stacking plate and the shuttle member.  
         [0018]     More preferably, further comprising a locker passing through the stacking base upward and downward and caught into the reject box provided below the stacking base, wherein the locker is pushed by the driving plate in a state where the stacking plate opens the reject slot and thus being caught into the reject box.  
         [0019]     Preferably, both ends of the stacking plate are supported on guide rods which are positioned on the stacking base at a predetermined height, the guide rod including a restitution member which causes the stacking plate to move toward the separation plate.  
         [0020]     The stacking plate and the driving plate are provided with interconnecting pieces at corresponding positions thereof, respectively, so that the driving plate moves together with the stacking plate when the driving plate moves a predetermined distance from its initial position.  
         [0021]     Preferably, a lower portion of the push bar of the shuttle member is connected to a connecting shaft, the driving plate is rotatably mounted with a link shaft, and both ends of a connecting link are rotatably connected to the connecting shaft and the link shaft, respectively, so that a movement of the driving plate causes the shuttle member to rotate.  
         [0022]     The delivery clamp module includes a clamp guide and a clamp assembly moving along the clamp guide, and the clamp assembly clamps the media through cooperation between a clamp base and a clamp arm.  
         [0023]     According to another aspect of the present invention, there is provided a method for rejecting media which a customer did not take out of the media dispenser, comprising the steps of: returning the media onto the stacking plate by a clamp assembly; opening a reject slot by allowing a driving plate to be moved by a driving source and the stacking plate to be moved together with the driving plate; and dropping the media as the clamp assembly unclamps the media through the opened reject slot.  
         [0024]     The step of dropping the media, stacking wheels rotate in order to guide the media toward the reject box.  
         [0025]     According to the present invention so constructed, since the media which the customer did not take out can be rejected at a time, there are advantages in that it is more convenient to reject the media and easy to design the structure for rejecting the media. In addition, the media are prevented from being stolen since the reject box is not separated from the media dispenser while an inlet of the reject box is opened.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0040]     Hereinafter, a preferred embodiment of a media dispenser according to the present invention will be described in detail with reference to the accompanying drawings.  
         [0041]     First,  FIG. 2  is a side view generally showing the embodiment according to the present invention.  FIG. 3  is a schematic perspective view showing the embodiment according to the present invention.  
         [0042]     Referring to the figures, a media dispenser of the embodiment according to the present invention comprises a delivery module  1 , a stacking module  3 , and a delivery clamp module  5 . The delivery module  1  serves to separate numbers of media from a media box (not shown), in which the media are stored, one by one and feed the media fed through a feed module (not shown) to a predetermined position. While feeding the media, the delivery module  1  also serves to divide the media into ones to be rejected and the others to be discharged by sensing thickness of the media. Reference numeral  4  designates a reject box.  
         [0043]     The stacking module  3  serves to collect desired numbers of the media fed through the delivery module  1  and then feed them to the delivery clamp module  5 . The delivery clamp module  5  serves to deliver the media fed from the stacking module  3  to a position, where a customer may take out the media at a time.  
         [0044]     Referring next to  FIG. 4 , the delivery module  1  will be described in detail. As shown in the figure, guide plates  10  and  10 ′ are spaced apart from each other in parallel. Each of the guide plates  10  and  10 ′ is substantially shaped in rectangular plate. Upper ends of the respective guide plates  10  and  10 ′ are provided with upper end flanges  12  and  12 ′ which are bent generally outwardly to be perpendicular to the guide plates  10  and  10 ′. The guide plates  10  and  10 ′ need not be configured so that each of them is a single piece.  
         [0045]     The upper end flanges  12  and  12 ′ of the guide plates  10  and  10 ′ are mounted with a clamp guide  20 . The clamp guide  20  is a portion that movably supports a clamp assembly  160  of the delivery clamp module  5 .  
         [0046]     The guide plate  10 ′ is mounted with a driving motor  30 . The driving motor  30  provides a driving force for feeding the media in the delivery module  1 . A rotational shaft  31  of the driving motor  30  is mounted with a driving pulley  32 . The driving belt  33  which is a timing belt is wound on the driving pulley  32 .  
         [0047]     The driving belt  33  is also wound on a driven pulley  37  which rotates about a rotational shaft  35  both ends of which are supported in the guide plates  10  and  10 ′. The driven pulley  37  is provided on the guide plate  10 ′. Thus, the driving force of the driving motor  30  is transferred to the driven pulley  37  through the driving belt  33 . The rotational shaft  35  is provided with a connecting pulley  38  coaxially with the driven pulley  37 . A connecting belt  39  which is a timing belt is wound on the connecting pulley  38  that rotates integrally with the rotational shaft  35 .  
         [0048]     In a lower portion of the guide plate  10 ′, a first driven pulley  40  is rotatably mounted to a separate guide plate (i.e., a guide plate of the feed module provided below the delivery module  1 ) (see  FIG. 4 ). For reference, although the first driven pulley  40  is not shown in  FIG. 3 , the connecting belt  39  is wound on a second driven pulley  40 ′. The guide plate  10 ′ is provided with the second driven pulley  40 ′ on which the connecting belt  39  wound on the first driven pulley  40  is also wound. The second driven pulley  40 ′ is installed so as to rotate integrally with a rotational shaft  41  both ends of which are supported in the guide plates  10  and  10 ′. A driving gear  42  is installed on an end of the rotational shaft  41  which protrudes from an outer side surface of the guide plate  10 . The driving gear  42  is rotated integrally with the second driven pulley  40 ′ by the rotational shaft  41 . On the rotational shaft  41 , rollers  43  are mounted spaced apart by predetermined intervals from each other between the guide plates  10  and  10 ′.  
         [0049]     A tension pulley  44  for controlling a tension of the connecting belt  39  is installed on the guide plate  10 ′ while the tension pulley  44  is mounted in a tension bracket  44 ′. The tension pulley  44  may control the tension of the connecting belt  39  by adjusting the mounting position of the tension bracket  44 ′.  
         [0050]     A rotational shaft  45  is installed so that both ends of the rotational shaft  45  are supported in the guide plates  10  and  10 ′. The rotational shaft  45  is installed in parallel with the rotational shaft  41 . A driven gear  46  is installed on the rotational shaft  45  on the outer side surface of the guide plate  10  to be engaged with the driving gear  42 . The driving gear  42  and the driven gear  46  may be installed on an outer side surface of the guide plate  10 ′, so that the driving force is transferred from the rotational shaft  41  to the rotational shaft  45 .  
         [0051]     A plurality of rollers  48  are installed on the rotational shaft  45  between the guide plates  10  and  10 ′. The plurality of the rollers  48  includes feed rollers which are in contact with the media and transmit a driving force for feeding them and a crown roller on which a delivery belt  50  is wound. For convenient of description, reference numerals are not additionally given thereto. In the present embodiment, the rotational shaft  45  is provided with three of the rollers  48 , wherein the center one is the crown roller and both the side ones are the feed rollers.  
         [0052]     The delivery belt  50  is wound on the crown roller of the rollers  48 . The delivery belt  50  which is wound on the roller  48  is in direct contact with the media and thus serves to feed them. The feed rollers among the rollers  48  on which the delivery belt  50  is not wound are installed at positions corresponding to feed rollers of the rollers  43  provided on the rotational shaft  41 .  
         [0053]     In the present embodiment where only the one delivery belt  50  is used, the delivery belt  50  is wound on rollers  52 ,  53 ,  54 ,  55 ,  56 , and  57  mounted on roller shafts  52 ′,  53 ′,  54 ′,  55 ′,  56 ′, and  57 ′, respectively. The rollers  52 ,  53 ,  54 ,  55 ,  56 , and  57  are crown rollers, and the rollers  56  include feed rollers.  
         [0054]     First and second media guides  61  and  62  for guiding the media fed by the conveyer belt  50  are installed between the guide plates  10  and  10 ′. Although each of the media guides  61  and  62  is formed to consist of a single molded piece in the present embodiment, it may be formed to consist of at least two of molded pieces with a similar shape and arranged in parallel with each other. The constitution of the media guides  61  and  62  is well shown in  FIG. 5 . The rollers  52 ,  53 ,  54 ,  55 ,  56 , and  57  are rotatably mounted in the media guides  61  and  62 .  
         [0055]     The first and second media guides  61  and  62  are separately manufactured and are integrally assembled to each other, and rotate about the rotational shaft  45  so that upper ends of the media guides are angled out of the guide plates  10  and  10 ′. The rotational shaft  45  is a center of the rotation of the first and second media guides  61  and  62 . That is, an assembly including the first and second media guides  61  and  62  rotates about the rotational shaft  45  so as to protrude out of the guide plates  10  and  10 ′. The rotation of the media guides  61  and  62  about the rotational shaft  45  is intended to remove the media jammed during the feeding.  
         [0056]     Further, a locker mechanism  65  is provided such that the first and second media guides  61  and  62  are kept mounted at a correct position during the operation of the media dispenser.  
         [0057]     Before describing the locker mechanism  65 , components provided on the media guides  61  and  62  corresponding thereto will be first described with reference to  FIG. 6 . The guide plates  10  and  10 ′ are formed with locking slots  14 , respectively. The locking slots  14  are provided in upper ends of the guide plates  10  and  10 ′ in which a guide step  14 ′ is formed along a portion of a circumference of each locking slot  14 . The guide steps  14 ′ are formed to downwardly incline to an end of the guide plates  10  and  10 ′. A lower leading end of each guide step  14 ′ is provided with a seating slot  15  communicating with the locking slot  14 . The seating slots  15  extend by a predetermined length toward the lower portion of the guide plates  10  and  10 ′ 
         [0058]     An interconnecting slot  65 ′ is bored through the second media guide  62  to be opened at both side ends of the second media guide  62 . Here, as shown in  FIG. 5 , the interconnecting slot  65 ′ is provided at positions corresponding to the locking slots  14 . The interconnecting slot  65 ′ is formed with a guide portion  65 ′ g  and a catching portion  65 ′ c  perpendicular to each other. The catching portion  65 ′ c  extends to the same direction as the seating slot  15 .  
         [0059]     Both ends of a locker shaft  66  are seated into the interconnecting slot  65 ′. The locker shaft  66  is formed with a length so that both the ends thereof can be seated into the locking slots  14 . That is, the locker shaft  66  has a length so that both the ends thereof protrude from both side ends of the guide plates  10  and  10 ′. Both the ends of the locker shaft  66  are also supported by locker springs  67 . The locker springs  67  generate an elastic force which intends the locker shaft  66  to seat on the catching portion  65 ′ c.    
         [0060]     Referring again to  FIG. 4 , the second media guide  62  is mounted with an idle roller  69 . The idle roller  69  is provided at a position corresponding to the rotational shaft  35 . A plurality of the idle rollers  69  may be installed, so that the idle rollers  69  rotate due to the movement of the media and guide the movement of the media. The idle rollers  69  may be rotatably installed separately from each other.  
         [0061]     A diverter  70  is provided at a portion of the media feeding path after the media pass through the idle rollers  69 . The diverter  70  serves to normally discharge or to reject the media. The diverter  70  is driven by a solenoid  71  provided on the outer side surface of the guide plate  10 ′. The diverter  70  serves to guide the media to one of two media feeding paths by turning on/off the solenoid  71 .  
         [0062]     As shown in  FIG. 5 , third, fourth, and fifth media guides  73 ,  74 , and  75  are provided to correspond to the first and second media guides  61  and  62 . Predetermined gaps are provided between the third, fourth, and fifth media guides  73 ,  74 , and  75  and the first and second media guides  61  and  62 , so that the media are fed through the gaps. A predetermined gap is also provided between the fourth and fifth media guides  74  and  75 , and thus, defines a path for feeding the media to the reject box after the media pass therebetween.  
         [0063]     It is preferred that each of the media guides  73 ,  74 , and  75  be formed into a single molded piece. However, each of the media guides  73 ,  74 , and  75  may be formed to consist of a plurality of pieces with the same shape and arranged in parallel with each other. The third, fourth, and fifth media guides  73 ,  74 , and  75  are fastened and installed to the guide plates  10  and  10 ′. For example, the third, fourth, and fifth media guides  73 ,  74 , and  75  are fastened to the guide plates  10  and  10 ′ by means of screws which penetrate the guide plates  10  and  10 ′.  
         [0064]     The predetermined gap is formed between the first and third media guides  61  and  73 , and thus, the third media guide  73  guides the media to be fed. The predetermined gap is also formed between the fourth and fifth media guides  74  and  75 , so that the path wherein the media are rejected through the gap is defined. The predetermined gap is also formed between the second and fifth media guides  62  and  75 , so that the path through which the media are fed to the stacking module  3  is defined.  
         [0065]     A plurality of rollers  77  are mounted on the rotational shaft  35  at positions corresponding to interior of the fourth media guide  74 . The plurality of the rollers  77  are provided at positions corresponding to the idle rollers  69 . Most of the rollers  77  are feed rollers which rotate due to the rotation of the rotational shaft  35  and thus feed the media. One of the rollers  77  is a crown roller on which a reject belt  85 , which will be described below, is wound.  
         [0066]     The first media guide  61  is provided with a thickness sensing unit  80  which prevents at least two sheets of media from discharging at a time by sensing a thickness of the media passing between the first and third media guides  61  and  73 . Description of the thickness sensing unit  80  is omitted since it is not a feature of the present invention.  
         [0067]     In order to reject the media through the gap between the fourth and fifth media guides  74  and  75 , the reject belt  85  is provided. The reject belt  85  is wound on the crown roller among the rollers  77  provided on the rotational shaft  35  and also wound on one of rollers  87  rotatably mounted on a roller shaft  87 ′ provided in the fourth media guide  74 . The roller shaft  87 ′ is provided with a plurality of the rollers  87  which consist of a crown roller on which the reject belt  85  is wound and feed rollers which feed the media.  
         [0068]     The fifth media guide  75  is provided with a roller  89  which is rotated while being brought into close contact with the reject belt  85 . The roller  89  is a kind of crown roller. The fifth media guide  75  is mounted with idle rollers  91  corresponding to the rollers  87 . The idle rollers  91  are provided corresponding to the feed rollers among the rollers  87 .  
         [0069]     The fifth media guide  75  is mounted with a roller  93  corresponding to a roller  57  of the second media guide  62 . The roller  93 , which is a kind of a crown roller, is in close contact with the delivery belt  50  and feeds the media. The fifth media guide  75  is also provided with idle rollers  95  at positions corresponding to rollers  56  of the second media guide  62 . The idle rollers  95  are provided at positions corresponding to the feed rollers among the rollers  56 .  
         [0070]     Referring next to  FIGS. 7   a ,  7   b , and  8 , the stacking module  3  will be described.  
         [0071]     An inner side surface of the guide plate  10 ′ is mounted with a driving motor  100 . The driving motor  100  drives a wheel rotating shaft  105 . One end of the wheel rotating shaft  105  is connected to the driving motor  100 , and the other end of the wheel rotating shaft  105  is supported in the guide plate  10 .  
         [0072]     The wheel rotating shaft  105  is mounted with a plurality of stacking wheels  110 . The plurality of the stacking wheels  110  are mounted on the wheel rotating shaft  105  at certain intervals. In the present embodiment, although two pairs, i.e., four, of the stacking wheels are employed, the number of them may be designed variously according to the width or length of the media. The stacking wheels  110  are rotated by a driving force of the driving motor  100 .  
         [0073]     The stacking wheels  110  are provided with a plurality of tangent wings  112  so as to extend in the tangential direction along outer circumference surface of the stacking wheels  110 . The media are inserted between the outer circumference surfaces of the stacking wheels  110  and the tangent wings  112  one by one, and then, fed to a stacking plate  140 , which will be described below, by means of the rotation of the stacking wheels  110 .  
         [0074]     A stacking base  120  is mounted to the guide plates  10  and  10 ′ by fixing both side ends of the stacking base  120  to the guide plates  10  and  10 ′. A front end of the stacking base  120  is positioned adjacent to the stacking wheels  110 . The stacking base  120  is substantially shaped in a rectangular plate with a width corresponding to a width between the guide plates  10  and  10 ′. Both the side ends of the stacking base  120  are formed with side walls  122  to extend, respectively. Such a stacking base  120  is provided with a structure for stacking the media.  
         [0075]     First, separation plates  124  are provided to be positioned between the stacking wheels  110 . The separation plates  124  are provided at the front end of the stacking base  120 . However, the separation plates  124  are not always provided at the front end of the stacking base  120 . The separation plates  124  serve to separate the media which are inserted between the tangent wings  112  of the stacking wheels  110  and fed. The separation plates  124  are provided to incline between the stacking wheels  110 . The separation plates  124  incline about perpendicularly to the tangential direction of a rotating trace of the stacking wheels  110 . Particularly, the separation plates  124  downwardly incline to the stacking plate  140 , which will be described below.  
         [0076]     The stacking base  120  is formed with a reject slot  126 . The reject slot  126 , which is bored through the stacking base  120  upward and downward, is a portion communicating with an inlet of the reject box  4 , that is, a portion wherein the media which were not delivered to the customer and are returned are fed to the reject box. The reject slot  126  is formed adjacent to proximal end portions of the separation plates  124 .  
         [0077]     A rear end of an upper surface of the stacking base  120  is provided with a driving motor  130 . An output shaft of the driving motor  130  is provided with a motor gear  132 . A driving force of the driving motor  130  is transferred to the motor gear  132  through a transmission. A connecting gear shaft  134  is provided so that both ends thereof are supported in the side walls  122 . The connecting gear shaft  134  is mounted with two connecting gears  135  and  135 ′. The respective connecting gears  135  and  135 ′ rotate integrally with the connecting gear shaft  134 . The connecting gears  135  and  135 ′ are engaged with the motor gear  132  and a driving gear  137 ′, which will be described below, respectively.  
         [0078]     A driving shaft  136  is installed so that both ends thereof are supported in the side walls  122 . The driving shaft  136  is installed in parallel with the connecting gear shaft  134 . The driving shaft  136  is provided with driving gears  137  and  137 ′. The driving gear  137 ′ consists of a larger gear portion and a smaller gear portion, wherein the smaller gear portion is engaged with the connecting gear  135 ′.  
         [0079]     The upper surface of the stacking base  120  is provided with a driving plate  138 . The driving plate  138 , which is shaped in a plate with a predetermined area, moves on the stacking base  120 . The driving plate  138  is provided with a front end inclined portion  138 ′ which upwardly inclines in the direction of the driving shaft  136 . The front end inclined portion  138 ′ serves to drive a locker  156 , which will be described below.  
         [0080]     The driving plate  138  is provided with racks  139  and  139 ′. The racks  139  and  139 ′ extend along both side ends of the driving plate  138  toward the driving gears  137  and  137 ′, respectively. Gear portions of the racks  139  and  139 ′ are engaged with the driving gears  137  and  137 ′, so that the racks  139  and  139 ′ receive the driving force of the driving motor  130 .  
         [0081]     Both the side ends of the driving plate  138  are provided with interconnecting pieces  138   m  so that the driving plate  138  is interconnected with the stacking plate  140  with a time lag. The interconnecting pieces  138   m  vertically protrude upward from the driving plate  138 .  
         [0082]     The stacking base  120  is provided with the stacking plate  140 . The stacking plate  140  is provided at a potion which is spaced apart by a predetermined height from the upper surface of the stacking base  120 . The stacking plate  140  is positioned above the reject slot  126  at an initial position of the stacking plate  140 .  
         [0083]     The stacking plate  140  is provided with interconnecting pieces  141 . The interconnecting pieces  141  are selectively caught to the interconnecting pieces  138   m  of the driving plate  138  and thus cause the stacking plate  140  to be moved by the driving force of the driving motor  130 . To this end, the interconnecting pieces  141  are formed to be vertically bent downward from the stacking plate  140 . For reference, if the stacking plate  140  moves due to the interconnection of the interconnecting pieces  141  and  138   m , the reject slot  126  is opened. Therefore, it is possible to feed the media to the reject box  4 .  
         [0084]     The stacking plate  140  is movably supported on guide rods  142  installed along both the side ends of the stacking base  120 . The guide rods  142  are installed at a height where the driving plate  138  is not hindered from moving on the stacking base  120 . The guide rods  142  penetrate and movably support the stacking plate  140 . The guide rods  142  are provided with restitution members  143 , respectively. The restitution member  143  is a coil spring, one end of which is caught to a step formed on the guide rod  142  itself and the other end of which is supported on the stacking plate  140 . Here, the restitution members  143  generate an elastic force in the direction where the stacking plate  140  returns to its initial position.  
         [0085]     The center of the stacking plate  140  is provided with a bar shaft  145 . Both ends of the bar shaft  145  are supported in the stacking plate  140 . To this end, the corresponding portions of the stacking plate  140  in which both the ends of the bar shaft  145  are supported are downwardly bent, and the bar shaft  145  penetrates the corresponding portions in order to be installed.  
         [0086]     The bar shaft  145  is provided with shuttle members  146 . A push bar  147  is formed at an end of each shuttle member  146  to extend in the perpendicular direction to the bar shaft  145 . The push bars  147  serve to push the media, which are fed by the stacking wheels  110  and erected on the stacking plate  140 , in the direction of the stacking wheels  110 . As described above, since the push bars  147  push the media, a plurality of sheets of the media are erected on the stacking plate  140  evenly. The push bars  147  are connected to each other through a connecting shaft  148 . The connecting shaft  148  is connected to lower portions of the push bars  147 , and causes the push bars  147  to be rotated about the bar shaft  145  by a pull operation of a link shaft  151 , which will be described below.  
         [0087]     In the meantime, a connecting link  150  is provided so that the push bars  147  interconnect with the driving plate  138 . Both ends of the connecting link  150  are connected to the connecting shaft  148  and the link shaft  151  mounted to the driving plate  138 , respectively.  
         [0088]     Both ends of the link shaft  151  are supported in shaft supporting pieces  152  provided on the driving plate  138 , respectively. The shaft supporting pieces  152  may be formed integrally with the driving plate  138 , or mounted thereto after manufactured separately. The shaft supporting pieces  152 , which are spaced apart by a predetermined interval from each other so as to support both the ends of the link shaft  151 , are provided with elongated holes  153  through which the link shaft  151  passes. The link shaft  151  is seated in the elongated holes  153  in order for the shuttle members  146  including the push bars  147  to be backward retracted and push the media uniformly when a large number of the media are stacked between the push bars  147  and the stacking wheels  110 .  
         [0089]     Elastic members  154  are connected to both the ends of the link shaft  151  at one ends thereof, respectively. The other ends of the elastic members  154  are connected to the driving plate  138 . Thus, the elastic members  154  elastically support the link shaft  151 , and make it possible for the push bars  147  to elastically push the media.  
         [0090]     The stacking base  120  is provided with a locker shaft  155 . The locker shaft  155  is installed at an opposite position to the stacking plate  140 . Although both ends of the locker shaft  155  are supported in the side walls  122 , it is not necessarily so. The locker shaft  155  is provided with the locker  156 .  
         [0091]     The locker  156  is caught into a portion of the reject box provided below the stacking base  120 , and thus, causes the reject box not to be detached from the media dispenser inadvertently. In particular, the locker  156  serves to fasten the reject box so that the reject box is not removed out of the media dispenser while its inlet is opened. To this end, the stacking base  120  is formed with a through hole  156   h  at a position corresponding to the locker  156 . The locker  156  is supported by a spring  156 ′ in order not to protrude below the stacking base  120  at a normal state.  
         [0092]     In the meantime, as shown in  FIG. 7   b , the driving plate  138  is formed with first, second, third, and fourth protruding sensing pieces  157  ( 157   a ,  157   b ,  157   c , and  157   d ). Clamp and dump sensors  158  and  159  are provided on the stacking base  120  corresponding to a movement trace of the sensing pieces  157 . The clamp and dump sensors  158  and  159  sense positions of the sensing pieces  157  and control the driving motor  130 . For reference, as the clamp and dump sensors  158  and  159  sense the second and fourth sensing pieces  157   b  and  157   d , respectively, it is recognized that the driving plate  138  is in its initial position. If the first sensing piece  157   a  is sensed by the clamp sensor  158 , it is recognized that the driving plate  138  is in a clamping position. In addition, if the third sensing piece  157   c  is sensed by the dump sensor  159 , it is recognized that the driving plate  138  is in a dumping position where the reject slot  126  is opened.  
         [0093]     Referring next to  FIGS. 9 and 10 , the delivery clamp module  5  will be described. The delivery clamp module  5  is configured so that the clamp assembly  160  is movably installed in the clamp guide  20 .  
         [0094]     The clamp assembly  160  is provided with a delivery tray  162 . Both side ends of the delivery tray  162  are provided with side walls  162 ′ which protrude by a predetermined height. The delivery tray  162  is movably supported in the clamp guide  20 . To this end, both the side ends of the delivery tray  162  are provided with connecting brackets  163 , respectively. The connecting brackets  163  are fastened to inner members of slide rails (not shown) provided in the clamp guide  20 . When assembling them, the connecting brackets  163  are first mounted to the inner members, and then, the delivery tray  162  is fastened to the connecting brackets  163 .  
         [0095]     Each of both outer side surfaces of the side walls  162 ′ of the delivery tray  162  is provided with a magnet mounting member  164 . The magnet mounting member  164  is provided with a magnet for sensing a position of the delivery tray  162  by cooperating with a plurality of magnetic field sensors  164 ′ provided on the clamp guide  20  (see  FIG. 3 ).  
         [0096]     A tray delivery motor  165  provides a driving force for moving the delivery tray  162 . The tray delivery motor  165  is installed on the delivery tray  162 . An output shaft of the tray delivery motor  165  is provided with a motor gear  165 ′, which is engaged with one of rack interconnecting gears  166 ′ coaxially installed to a delivery driving shaft  166  to transfer the driving force. The delivery driving shaft  166 , both ends of which are rotatably supported in the side walls  162 ′, are provided with the rack interconnecting gears  166 ′ adjacent to the respective side walls  162 ′. The rack interconnecting gears  166 ′ are engaged with racks (not shown) provided in the clamp guide  20  and thus cause the delivery tray  162  to linearly reciprocate with respect to the clamp guide  20 .  
         [0097]     The delivery tray  162  is mounted with a clamp base  168 . The clamp base  168 , which supports a side surface of a bundle of the stacked media, is rotatably mounted in the delivery tray  162 . The clamp base  168  is formed with a plurality of interference preventing slots  168 ′ so that the clamp base  168  is prevented from interfering with the stacking wheels  110  when rotating. The plurality of the interference preventing slots  168 ′ are arranged side by side to be opened to a front end of the clamp base  168 .  
         [0098]     The clamp base  168  is provided with an extension clamp  169 . The extension clamp  169  forward protrudes a little more than the clamp base  168 . The extension clamp  169  is also provided with interference preventing slots  169 ′ in the same manner as in the clamp base  168 . The extension clamp  169  can move back and forth along guide shafts  170 , which are provided in both side ends of the clamp base  168 , respectively. Each guide shaft  170  is provided with an elastic member  170 ′ for pushing the extension clamp  169  to the front end of the clamp base  168 . The elastic member  170 ′, both ends of which are supported by the extension clamp  169  and the clamp base  168 , respectively, is a coil spring surrounding an outer peripheral surface of the guide shaft  170 . The extension clamp  169  is designed so that the guide shafts  170  penetrate portions of extension clamp  169  supporting the elastic members  170 ′, and thus, is subjected to an elastic force of the elastic members  170 ′.  
         [0099]     Both rear side ends of the clamp base  168  are provided with connecting arms  171 , respectively. The connecting arms  171  are formed to stand perpendicular to a surface of the clamp base  168 , and thus, face the side walls  162 ′. A supporting piece  172  is provided on the clamp base  168  to face each of the connecting arms  171  with a predetermined spacing therebetween.  
         [0100]     The clamp base  168  is provided with a media sensor  173  for sensing the clamped media. The media sensor  173  senses whether the media are clamped, whether the media are delivered to the customer, or the like. A media sensor  173  cooperates with a reflecting member  184 ′ provided on a clamp arm  184 , which will be described below, and thus, performs the sensing operation.  
         [0101]     A base rotating motor  175  for driving the clamp base  168  is provided on the delivery tray  162 . The driving force of the base rotating motor  175  is transferred through a plurality of gears. That is, an output shaft of the base rotating motor  175  is provided with a motor gear  175 ′, and a driving shaft  176  installed on the delivery tray  162  is provided with a first shaft gear  176 ′ engaged with the motor gear  175 ′. Both ends of the driving shaft  176  are also provided with second shaft gears  177 , respectively. The second shaft gears  177  are engaged with connecting gears  178  installed on the delivery tray  162 , respectively. The connecting gears  178  are engaged with rotation gears  179  provided on the connecting arms  171  of the clamp base  168 .  
         [0102]     Here, the second shaft gear  177  and the connecting gear  178  are rotatably supported in each gear bracket  180 . The gear brackets  180  are installed on the delivery tray  162 . A side of the gear bracket  180  extends to be positioned between the connecting arm  171  and the supporting piece  172 . Then, the other side of the gear bracket  180  also serves to support the output shaft of the base rotating motor  175 . Such a gear bracket  180  is provided at each of both the side ends of the delivery tray  162 .  
         [0103]     The rotation gear  179  is integrally installed on a gear shaft  179 ′, which operates integrally with the connecting arm  171  and the supporting piece  172 . That is, the connecting arms  171 , the supporting pieces  172 , the gear shafts  179 ′, and the rotation gears  179  integrally rotate. However, the gear shafts  179 ′ may rotate with respect to the gear brackets  180  and the side walls  162 ′ of the delivery tray  162 .  
         [0104]     A configuration for controlling the rotation of the clamp base  168  will be described. Clamp sensors  182  are provided on the delivery tray  162  adjacent to the respective connecting arms  171 . A sensing piece  183  is provided on each of the gear shafts  179 ′ to be selectively positioned between light emitting and light receiving portions of the clamp sensor  182 . Here, while both the clamp sensors  182  are installed on the delivery tray  162  in the same direction, the sensing pieces  183  extend in the different directions from each other by 90 degrees. Since the clamp base  168  normally and reversely rotates only within an angular range of 90 degrees, positions of the clamp base  168  are alternately sensed by both the clamp sensors  182 .  
         [0105]     The clamp arm  184  is rotatably mounted on the clamp base  168 . That is, both ends of an arm rotational shaft  185  which is mounted to a rear end of the clamp arm  184  are rotatably supported in supporting brackets  185   b  of the clamp base  168 , respectively.  
         [0106]     The clamp arm  184  is shaped to be prevented from interfering with the stacking wheels  110  when the clamp arm  184  rotates. That is, in the present embodiment, the clamp arm  184  branches off into three portions. The portions branched from the clamp arm  184  are formed not to overlap with the interference preventing slots  168 ′. The reflecting member  184 ′ is provided on the clamp arm  184  at a position corresponding to the media sensor  173  of the clamp base  168 . The reflecting member  184 ′ serves to reflect a light from the light emitting portion to the light receiving portion of the media sensor  173 . Due to the reflecting member  184 ′, only the one media sensor  173  is provided on the clamp base  168 .  
         [0107]     A driving force for rotating the clamp arm  184  is generated by an arm rotating motor  186  installed on the clamp base  168 . The driving force of the arm rotating motor  186  is transferred to a rotational shaft gear  185 ′ provided on the arm rotational shaft  185  through a motor gear  186 ′ and a connecting gear  187 . Therefore, the arm rotational shaft  185  is rotated together with the clamp arm  184  by the driving force of the arm rotating motor  186 .  
         [0108]     A configuration for controlling operation of the clamp arm  184  will be described. Any one of the supporting brackets  185   b  is mounted with two arm sensors  189  spaced apart by 90 degrees with respect to the arm rotational shaft  185  from each other. The arm rotational shaft  185  is provided with a sensing piece  190  (see  FIG. 10 ). That is, the two arm sensors  189  are provided on a movement trace of the sensing piece  190 , so that the arm sensors  189  sense positions of the sensing piece  190  according to the rotation of the arm rotational shaft  185 .  
         [0109]     The clamp arm  184  is provided with push fingers  192 . Each of the push fingers  192  is shaped in a curved surface so that its front end generates a predetermined elastic force. The push fingers  192  are formed not to overlap with the interference preventing slots  168 ′ of the clamp base  168 . In the present embodiment, four of the push fingers  192  are integrally formed and provided at corresponding positions of a surface of the clamp base  168 .  
         [0110]     The push fingers  192  are supported by elastic supporting members  194  and mounted on the clamp arm  184 . In the present embodiment, the elastic supporting members  194  are provided around an elastic supporting shaft  193  both ends of which are supported in the clamp arm  184 . The elastic supporting members  194  rotate about the elastic supporting shaft  193 , so that one ends thereof push the push fingers  192  and thus generate an elastic force. The push fingers  192  serve to press the media to the clamp base  168  regardless of the number of the media provided between the clamp base  168  and the clamp arm  184 .  
         [0111]     Hereinafter, the operation of the media dispenser and the media rejecting method according to the present invention so constructed will be described in detail.  
         [0112]     In the media dispenser of the present invention, the media are separated from the media box one by one by means of an operation of the customer, pass through the feed module, and then, are fed through the delivery module  1 . In the delivery module  1 , the media are guided by the delivery belt  50  and then fed to the stacking wheels  110 . The media fed to the stacking wheels  110  are stacked on the stacking module  3  as many as the customer wants.  
         [0113]     Referring to  FIGS. 11   a  to  11   i  and  12   a  to  12   c , it will be described that the media are stacked on the stacking module  3  as many as the customer wants and delivered to the customer.  
         [0114]     First, in order to stack a number of sheets of the media on the stacking plate  140 , the driving plate  138 , the stacking plate  140 , and the clamp assembly  160  should be positioned at their initial positions. Such a state is shown in  FIGS. 11   a  and  12   a . That is, the driving plate  138  and the stacking plate  140  move toward the separation plates  124  as close as possible. The clamp assembly  160  is positioned at a position where it is sensed by the intermediate one among the magnetic field sensors  164 ′.  
         [0115]     In addition, the clamp base  168  of the clamp assembly  160  hangs vertically downward. It is in a state where the sensing piece  183  at the relatively right side in  FIG. 9  is sensed by the corresponding clamp sensor  182 .  
         [0116]     Furthermore, the clamp arm  184  is in parallel with the delivery tray  162 . Therefore, the clamp arm  184  and the clamp base  168  are perpendicular to each other.  
         [0117]     In such a state, the media passing between the second and fifth the media guides  62  and  75  are inserted between the tangent wings  112  of the stacking wheels  110  one by one. Then, the stacking wheels  110  are rotated by the driving motor  100 , so that the media are fed by the stacking wheels  110 .  
         [0118]     If the media which have been inserted between the tangent wings  112  and rotated meet the separation plates  124 , the media are separated from the stacking wheels  110 . While being continuously pushed to the tangent wings  112  of the stacking wheels  110  by the push bars  147 , the media separated from the stacking wheels  110  by the separation plates  124  are guided along inclined surfaces of the separation plates  124 .  
         [0119]     Therefore, the media are supported and erected on the stacking plate  140  between the stacking wheels  110  and the push bars  147 . In such a manner, a number of sheets of the media are continuously erected on the stacking plate  140  one by one. Here, the push bars  147  push the media erected on the stacking plate  140  to be in close contact with the tangent wings  112 .  FIG. 11   b  shows that a number of sheets of the media are erected on the stacking plate  140 .  
         [0120]     However, if the number of the media erected between the stacking wheels  110  and the push bars  147  increases, the push bars  147  are pushed rearward. That is, while the shuttle members  146  are pushed, the connecting shaft  148 , the connecting link  150 , and the link shaft  151  overcomes the elastic force of the elastic members  154  and are also pushed. Therefore, the link shaft  151  moves in the elongated holes  153  according to the number of the erected media.  
         [0121]     If a customer&#39;s desired number of the media are stacked on the stacking plate  140 , the feeding of the media through the delivery module  1  is stopped. Then, the clamp arm  184  rotates. The clamp arm  184  is rotated by the driving force of the arm rotating motor  186 . That is, the driving force of the arm rotating motor  186  is transferred to the arm rotational shaft  185  through the motor gear  186 ′, the connecting gear  187 , and the rotational shaft gear  185 ′. Since the arm rotational shaft  185  is integral with the clamp arm  184 , the rotation of the arm rotating motor  186  causes the clamp arm  184  to rotate. Here, the push fingers  192  also rotate.  
         [0122]     The clamp arm  184  and the push fingers  192  rotate, so that the media comes into close contact with the clamp base  168 . Particularly, the push fingers  192  press the media to the clamp base  168  by means of the elastic force regardless of the number of the media. Such a state is shown in  FIG. 11   c.    
         [0123]     Next, the shuttle members  146  rotate. The shuttle members  146  rotate due to the movement of the driving plate  138  caused from the driving force of the driving motor  130 . That is, the connecting link  150  pulls the connecting shaft  148  by the movement of the driving plate  138 .  
         [0124]     Then, the driving force of the driving motor  130  is transferred to the driving shaft  136  through the motor gear  132  and the first and second connecting gears  135  and  135 ′. The driving force transferred to the driving shaft  136  is transferred to the racks  139  and  139 ′ through the driving gears  137  and  137 ′ provided on the driving shaft  136 . Therefore, the driving plate  138  provided with the rack  139  moves on the stacking base  120 . The driving plate  138  moves until the first sensing piece  157   a  is sensed by the clamp sensor  158 . Such a state is shown in  FIGS. 11   d  and  12   b.    
         [0125]     In a state where the shuttle members  146  incline toward the rear end of the stacking base  120 , the clamp assembly  160  moves to the right side in the figure, and simultaneously, the clamp base  168  rotates clockwise. Such a process is shown in  FIGS. 11   e  to  11   g.    
         [0126]     Next, the clamp assembly  160  is moved by the tray delivery motor  165 . That is, the driving force of the tray delivery motor  165  is transferred to one of the rack interconnecting gears  166 ′ through the motor gear  165 ′, so that the delivery driving shaft  166  rotates. The rotation of the delivery driving shaft  166  causes the rack interconnecting gears  166 ′, which are engaged with the racks provided in the clamp guide  20 , respectively, to move, so that the clamp assembly  160  moves.  
         [0127]     The clamp assembly  160  moves as above until the clamp assembly  160  is sensed by the leftmost one among the magnetic field sensors  164 ′ in  FIG. 3 . At the position where the clamp assembly  160  is sensed by the magnetic field sensor  164 ′, the media clamped by the clamp arm  184  and the clamp base  168  of the clamp assembly  160  are supported by the extension clamp  169  and prevented from sagging downward. In addition, the extension clamp  169  is caught to a portion of the clamp guide  20  and thus does not protrude out of the clamp guide  20 , so that only the media protrude. That is, the extension clamp  169  is caught to the portion at a front end of the clamp guide  20  and thus relatively retracted along the clamp base  168 . So to speak, the extension clamp  169  is relatively retracted along the guide shafts  170  while elastically deforming the elastic members  170 ′. Such a state is shown in  FIG. 11   i.    
         [0128]     Furthermore, if the customer takes out the media, the clamp assembly  160  moves in the opposite direction. The movement of the clamp assembly  160  causes the extension clamp  169  to protrude to its initial position. The clamp assembly  160  is moved to its initial state by the driving force of the tray delivery motor  165 . That is, the media dispenser gets ready for stacking media by request of the next customer. So to speak, the media dispenser becomes in the state shown in  FIG. 11   a . Here, the shuttle members  146  are moved to their initial state by the driving force of the driving motor  130 .  
         [0129]     In the meantime, if the customer has not yet taken out the media at the state shown in  FIG. 11   i , the media should be rejected and fed to the reject box  4 . Such a process is reversely performed in order from  FIG. 11   i  to  FIG. 11   d.    
         [0130]     In the state shown in  FIG. 11   d , the driving motor  130  causes the driving plate  138  to move in the direction of the driving motor  130 . The shuttle member  147  rotates no more, and moves together with the driving plate  138  with the rotated angle of the shuttle member  147  maintained. Here, the interconnecting pieces  138   m  of the driving plate  138  and the interconnecting pieces  141  of the stacking plate  140  are caught to each other, so that the stacking plate  140  is moved by the driving plate  138 .  
         [0131]     The stacking plate  140  is guided by the guide rods  142  and then moves. Particularly, the stacking plate  140  moves while elastically deforming the restitution members  143 . The driving plate  138  moves until the third sensing piece  157   c  of the driving plate  138  is sensed by the dump sensor  159 . Such a state is shown in  FIG. 12   c.    
         [0132]     In the meantime, the front end inclined portion  138 ′ of the driving plate  138  pushes the locker  156 . The locker  156  protrudes downward from the stacking base  120  and thus is caught into a groove formed on an upper surface of the reject box  4 . In such a state, when the media are rejected, the reject box  4  cannot get out of the media dispenser. For example, even if power is not supplied in the state shown in  FIG. 12   c , since an outsider cannot get the reject box  4  out of the media dispenser, it is possible to prevent an unexpected theft.  
         [0133]     If the stacking plate  140  is in the state shown in  FIG. 12   c , the reject slot  126  is opened. Therefore, the media clamped by means of the clamp base  168  and the clamp arm  184  may be rejected into the reject box  4  through the reject slot  126 . For reference, the reject box  4  is provided with an inlet for receiving the media rejected by the reject belt  85  and another inlet for receiving a bundle of the media on the clamp assembly  160 .  
         [0134]     If the clamp arm  184  is lifted at the state shown in  FIG. 12   c , the media clamped by means of the clamp base  168  and the clamp arm  184  are dropped into the reject box  4  through the reject slot  126 . Here, the rotation of the stacking wheels  110  causes all of the media to enter the reject box  4 .  
         [0135]     If the media are completely rejected, in order to erect media on the stacking plate  140  by request of the next customer, the respective components move to their initial states shown in  FIG. 11   a . Here, if the interconnecting pieces  138   m  and  141  are caught to each other no more as the driving plate  138  is moved to its initial position, the stacking plate  140  is moved to its initial position by the elastic force of the restitution members  143 .  
         [0136]     In addition, the shuttle members  146  are installed such that the push bars  147  incline toward the stacking wheels  110  according to the positions of the stacking plate  140  and driving plate  138  and the positional relationships between the connecting link  150 , the connecting shaft  148 , and the elastic members  154 .  
         [0137]     According to the stacking module of the media dispenser of the present invention so constructed and the control method thereof, the following advantages can be expected.  
         [0138]     In the present invention, a customer&#39;s desired number of the media are collected on the stacking module, clamped by the clamp assembly, and then delivered to the customer. The media which the customer has not yet taken out can be rejected with the media just clamped by the clamp assembly. Therefore, it can be easily performed that the media are delivered to the customer or rejected to the reject box.  
         [0139]     In addition, according to the present invention, since the reject box is automatically caught to the media dispenser in a state where the media are rejected, the reject box cannot be separated from the media dispenser. Therefore, there is an advantage in that possibility of the theft of the media is reduced.  
         [0140]     Furthermore, in the present invention, since the clamp assembly clamps and delivers the media at a time, it is possible to install the reject box wherever the clamp assembly reaches. Thus, it is advantageously possible to freely design the structure for rejecting the media.  
         [0141]     The scope of the present invention is not limited to the embodiment described and illustrated above but is defined by the appended claims. It will be apparent that those skilled in the art can make various modifications and changes thereto within the scope of the invention defined by the claims. Therefore, the true scope of the present invention should be defined by the technical spirit of the appended claims.  
         [0142]     For example, the wheel rotating shaft  105  mounted with the driving motor  100  and the stacking wheels  110  may be installed at portions where both the side ends of the stacking base  120  extend.
