Description:
CROSS REFERENCE 
     The present application claims the benefit of Korean Patent Application No. 10-2015-0065965 filed in the Korean Intellectual Property Office on May 12, 2015, the entire contents of which are incorporated herein by reference. 
     BACKGROUND 
     The present invention relates to a paper sheet redirecting unit capable of changing a direction of paper sheets to be fed, and sorting and discharging the paper sheets in different directions according to discrimination, and a paper sheet processing apparatus using the same. 
     In general, a paper sheet processing apparatus is designed to automatically count the number of paper sheets by a mechanical device, as well as valuable papers, such as checks. 
     Such a paper sheet processing apparatus  100  includes, as illustrated in  FIG. 1 , a housing  110  having an inner space to form its appearance. The housing  110  has an inlet hopper  111  formed at one side thereof which communicates with the inner space to feed a paper sheet to the inner space, a first hopper  191  formed at the other side thereof, from which the paper sheet fed from the inlet hopper  111  is discharged, and a second hopper  192  spaced apart from the first hopper  191 , from which a different type of paper sheet from the paper sheet discharged from the first hopper  191 . Also, the paper sheet processing apparatus includes a display  170  to display the type of the received paper sheet and the number of the counted paper sheets. 
     A lower portion of the inlet hopper  111  is provided with rollers to transfer the paper sheets to the inside of the housing  110 . If the rollers turn, the paper sheets stacked on the inlet hopper  111  are transferred in order, and then are separately discharged from the second hopper  192  and the first hopper  191 . 
     However, since the first hopper  191  and the second hopper  192  are placed in a vertical direction, the above counting machine can sort the paper sheet into only two types. If other hopper is installed to an upper portion or a lower portion, the height of the housing  110  is increased, which is inconvenient to count the paper sheets. 
     Also, since the first hopper  191  and the second hopper  192  face forward, the paper sheets raise dust in front of the machine, which may be harmful to a user. 
     A related background technology of the present invention is disclosed in Korean Utility Model No. 20-0452857 (registered on Mar. 16, 2011). 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a paper sheet redirecting unit capable of changing a direction of paper sheets to be fed, and sorting and discharging the paper sheets in different directions according to discrimination, and a paper sheet processing apparatus using the same. 
     According to one aspect of the present invention, there is provided a paper sheet redirecting unit for changing a direction of a paper sheet to be transferred, the paper sheet redirecting unit including: a one-side redirecting member configured to support one side of the paper sheet and change the direction of the paper sheet while transferring the paper sheet; and an other-side redirecting member configured to support the other side of the paper sheet in a state of coming in contact with the one-side redirecting member and to change the direction of the paper sheet while transferring the paper sheet, wherein if a power is transmitted to the one-side redirecting member or the other-side redirecting member, the one-side redirecting member and the other-side redirecting member are operated in company with each other, thereby discharging the paper sheet while changing the direction of the paper sheet to be inputted between the one-side redirecting member and the other-side redirecting member. 
     According to another aspect of the present invention, there is provided a paper sheet processing apparatus including: a housing equipped with the paper sheet redirecting unit; a sensing member configured to detect a paper sheet fed into an inner space of the housing; and a first sorting member configured to sort the paper sheet so that the paper sheet detected by the sensing member is guided to a paper sheet redirecting unit or in a direction from paper sheet redirecting unit. 
     With the above configuration, the present invention has an advantage in which since the direction of the paper sheet to be transferred by the paper sheet redirecting unit is changed, the direction of the paper sheet can be correctly changed. 
     Also, since the present invention detects the paper sheet transferred into the inner space of the housing, and sorts and discharges the paper sheets to both sides of the housing according to the detection, it is possible to sort the paper sheets according to the detection, and also to minimize the height of the housing. 
     In addition, since the detected paper sheets are sorted and discharged to both sides of the housing, it is possible to dust coming from the paper sheet to be discharged from being dispersed in front of the housing.

     DETAILED DESCRIPTION OF THE INVENTION 
     Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 
     As illustrated in  FIGS. 2 and 3 , a paper sheet processing apparatus according to a preferred embodiment of the present invention includes a housing  10 , a feeding member  20 , a transport member  30 , a sensing member  40 , a first sorting member  50 , a paper sheet redirecting unit  60 , and a second sorting member  70 . 
     First, a paper sheet includes a banknote, a check, a barcode voucher, a marketable security, a gift certificate, and so forth. 
     The housing  10  with an inner space has an inlet hopper  11  and a discharge hopper  12  which communicates with the inlet hopper  11 . 
     As illustrated in  FIGS. 2 to 6 , the inlet hopper  11  may be formed on the upper portion of the housing  10 , on which paper sheets to be fed to the inner space are stacked on the inlet hopper. Since the inlet hopper  11  is formed on the upper portion of the housing  10 , a user can conveniently use the paper sheets. 
     The discharge hopper  12  may be formed at a lower portion of the housing  10 , on which the paper sheets to be discharged outwardly are stacked. In case where two discharge hoppers  12  are provided, as illustrated in  FIGS. 2 and 3 , the discharge hoppers may be separately provided on both sides of the housing  10 . In case where three discharge hoppers are provided, as illustrated in  FIGS. 3 to 6 , one discharge hopper may be provided on a front or rear surface of the housing  10 , and two discharge hoppers may be provided on both sides. In this instance, in the case where the discharge hoppers  12  are provided on both sides, dust coming from the paper sheets to be discharged from the discharge hoppers  12  is discharged toward both sides of the housing  10 , thereby preventing the dust from scattering toward the user positioned in front of the housing  10 . That is, it is possible to minimize the damage of the scattered dust. 
     The feeding members  20  are provided to the inlet hopper  11  of the housing to feed the paper sheets into the inner space through the inlet hopper  11 . A plurality of feeding members  20  may be respectively installed to one side of the inlet hopper  11 , and may be rotated by a rotating force inputted from the exterior to feed the paper sheets by a frictional force. Accordingly, if rollers are rotated, the paper sheets can be sequentially fed into the inner space of the housing  10 . 
     The transport member  30  is configured to transport the paper sheets to be fed by the feeding members  20  to the inner space of the housing  10 , and has guide plates  31  and transport rollers  32 . 
     A plurality of guide plates  31  are installed from the inlet hopper  11  to the discharge hopper  12  in the inner space of the housing  10  in the state in which the guide plates are connected to each other, thereby guiding the transport of the paper sheets. 
     A plurality of transport rollers  32  are rotated by a driving member (not illustrated) to forcibly transfer the paper sheets guided by the guide plates  31 . The driving member may be an electric motor which is axially engaged to one transport roller  32 , or may be an electric motor which is axially engaged to the transport roller  32  to rotate any one of transport rollers  32  and a belt (not illustrated) interposed between the transport rollers  32 . 
     Since the transport roller  32  is rotated by operation of the driving member, the paper sheets can be transferred to the discharge hopper  12  provided on the front side of the housing  10  along the guide plates  31 . 
     The sensing member  40  is configured to detect the paper sheets fed into the inner space of the housing  10 , and may be provided to one or both sides of the transport member  30  to detect a counterfeit bill, a type or a damaged banknote among the paper sheets transferred by the transport member  30 . The sensing member  40  detects an ink color, a magnetic property contained in the ink, a material of the paper sheet, a thickness of the paper sheet, a secret code of the paper sheet, and so forth, and also detects a series number and type of the paper sheet by scanning one or both sides of the paper sheet. In addition, the sensing member  40  can scan the paper sheet to detect the extent of the damage, such as tear, cut, or wear, in the paper sheet. 
     The sensing member  40  can discriminate different types of paper sheets, such as the won, the dollar, the yen, or the like, and also can detect the counterfeit bill or the damaged banknote, as well as a denomination of the paper sheet. 
     The paper sheets detected by the sensing member  40  can be discharged and stacked on the respective discharge hoppers  12  according to the counterfeit bill, the type or the damaged banknote. 
     As illustrated in  FIGS. 3, 6, and 12 to 14 , the first sorting member  50  sorts the paper sheets to guide the paper sheets detected by the sensing member  40  or to guide the paper sheets in different directions. The first sorting member  50  can sort the paper sheets transferred by the transport member  30  in the state in which the first sorting member is placed adjacent to the transport member  30 . 
     The first sorting member  50  has a first sorter  51  and a first sorter driving member  52 . 
     The first sorter  51  is formed in a triangular shape with a sharp corner to sort the paper sheets transferred by the transport member  30  in different directions, and both sides of the first sorter have a flat guide surface or a recessed guide surface. 
     The first sorter  51  is rotatably installed to the front side of the housing  10  at a position between the discharge hopper  12  and the transport member  30  provided on the front side of the housing  10 . A plurality of first sorters  51  are provided at regular intervals to minimize air resistance on the guide surface in the process of sorting the paper sheets. 
     Specifically, since a wind produced from the guide surface when the first sorter  51  rotates in a clockwise or counterclockwise direction disperses, which can minimize the effect of the wind on the paper sheets. 
     If the first sorters  51  rotate in an upward direction and then the sharp corners of the first sorters face upwardly, the paper sheets transferred by the transport member  30  are guided downwardly by the guide surfaces. If the first sorters  51  rotate in a downward direction and then the sharp corners of the first sorters face downwardly, the paper sheets transferred by the transport member  30  are guided upwardly by other guide surfaces. Specifically, the paper sheets to be transferred upwardly are guided to the discharge hopper  12  provided on the front side of the housing  10 , and the paper sheets to be transferred downwardly are guided to the paper sheet redirecting unit  60  positioned at the lower portion of the housing  10 . 
     The first sorter driving member  52  may be a stepping motor or a solenoid which can rotate the first sorter  51  in a clockwise or counterclockwise direction. Accordingly, as the first sorter  51  is rotated upwardly or downwardly at a desired angle by the first sorter driving member  52 , the paper sheets to be transferred along the guide plates  31  can be guided in the upward or downward direction. 
     As illustrated in  FIGS. 7 to 11 , the paper sheet redirecting unit  60  is configured to change a direction of the paper sheet to be transferred and discharge it. The paper sheet redirecting unit  60  has a one-side redirecting member  61  configured to support one side of the paper sheet and change the direction of the paper sheet while transferring the paper sheet, and an other-side redirecting member  62  configured to support the other side of the paper sheet in a state of coming in contact with the one-side redirecting member  61  and to change the direction of the paper sheet while transferring the paper sheet. 
     If the power is transmitted to the one-side redirecting member  61  or the other-side redirecting member  62 , the one-side redirecting member  61  or the other-side redirecting member  62  work together to change the direction of the paper sheet to be fed between the one-side redirecting member  61  or the other-side redirecting member  62  and then discharge the paper sheet. Specifically, the paper sheet redirecting unit  60  is positioned adjacent to the first sorting member  50  to shift the left and right directions of the sorted paper sheet and then transfer the paper sheet to the lower portion of the housing  10 . 
     The one-side redirecting member  61  has a first one-side rotating member  61   a  rotatably provided, a second one-side rotating member  61   b  which is spaced apart from the first one-side rotating member  61   a  at a desired interval and is rotatably provided in a state of being offset from the first one-side rotating member  61   a  in a different direction, and a third one-side transmission member  61   c  which is interposed between the first one-side rotating member  61   a  and the second one-side rotating member  61   b  and comes into contact with one side of the paper sheet in a rotatable state in which one end and the other end are offset from each other. 
     The first one-side rotating member  61   a  and the second one-side rotating member  61   b  may be rollers, and the third one-side transmission member  61   c  may be a belt. Accordingly, if the power is transmitted to the first one-side rotating member  61   a  or the second one-side rotating member  61   b , the third one-side transmission member  61   c  may be rotated. 
     The other-side redirecting member  62  has a first other-side rotating member  62   a  rotatably provided to correspond to the first one-side rotating member  61   a , a second other-side rotating member  62   b  which is spaced apart from the first other-side rotating member  62   a  at a desired interval to correspond to the first other-side rotating member  62   a  and is rotatably provided in a state of being offset from the first other-side rotating member  62   a  in a different direction, and a third other-side transmission member  62   c  which is interposed between the first other-side rotating member  62   a  and the second other-side rotating member  62   b  to correspond to the third one-side transmission member  61   c  and comes into contact with the other side of the paper sheet in a rotatable state in which one end and the other end are offset from each other. 
     The one-side redirecting member  61  or the other-side redirecting member  62  may be connected to a driving unit (not illustrated) to transmit the power thereto. The driving unit may be an electric motor capable of transmitting a rotating force or a gear capable of transmitting a rotating force from the exterior. 
     In the state in which the driving unit is connected to any one of the first one-side rotating member  61   a , the second one-side rotating member  61   b , the first other-side rotating member  62   a  and the second other-side rotating member  62   b , when any one of the first one-side rotating member  61   a , the second one-side rotating member  61   b , the first other-side rotating member  62   a  and the second other-side rotating member  62   b  is rotated by the rotating force transmitted from the driving member, the third one-side transmission member  61   c  or the third other-side transmission member  62   c  can be rotated. Specifically, since the third one-side transmission member  61   c  and the third other-side transmission member  62   c  are brought into contact with each other, if one is rotated, the other is also rotated. 
     The first one-side rotating member  61   a  and the first other-side rotating member  62   a  respectively have rotational shafts  61   d  and  62   d  rotatably fixed to the housing  10 , and non-slip portions  61   e  and  62   e  enclosing outer peripheral surfaces of the rotational shafts  61   d  and  62   d  to prevent slippage of the third one-side transmission member  61   c  or the third other-side transmission member  62   c . Accordingly, since the rotational shafts  61   d  and  62   d  are rotated by the rotating force transmitted from the driving member, the third one-side transmission member  61   c  and the third other-side transmission member  62   c  can be rotated, without being slip, by the non-slip portions  61   e  and  62   e . In this instance, the second one-side rotating member  61   b  and the second other-side rotating member  62   b  may be provided with a non-slip portion to prevent the slippage. 
     As enlargedly illustrated in the left side in  FIG. 8 , the non-slip portions  61   e  and  62   e  may be made of rubber, plastic, or metal, and may have an outer peripheral surface with a center portion being bulged. The third one-side transmission member  61   c  and the third other-side transmission member  62   c  can be brought into contact with each other, so that the paper sheets can be easily transferred, without being slip. 
     As enlargedly illustrated in the right side in  FIG. 8 , the non-slip portions  61   e  and  62   e  may be formed in the shape of a cone. Specifically, a diameter b of one end may be larger than a diameter a of the other end. The third one-side transmission member  61   c  which is fixed to the first one-side rotating member  61   a  and the first other-side rotating member  62   a  in the cross state can be easily brought into contact with the non-slip portion  61   e  of the cone shape. Therefore, the third one-side transmission member  61   c  can be easily rotated, without being slip against the rotating non-slip portion  61   e.    
     The first other-side rotating member  62   a  and the second other-side rotating member  62   b  may be rollers, and the third other-side transmission member  62   c  may be a belt. Specifically, if the power is transmitted to the first other-side rotating member  62   a  or the second other-side rotating member  62   b , the third other-side transmission member  62   c  may be rotated. 
     The third one-side transmission member  61   c  and the third other-side transmission member  62   c  which are belts are preferably formed to be longer than a distance of the paper sheet. Accordingly, since the length of the belt is longer than the paper sheet, the other ends of the belts are brought into contact with each other in the case where the paper sheet is fed to one side of the belts. Both ends of the belts are brought into contact with each other even in the case where the paper sheet is positioned between the belts. One ends of the belts are brought into contact with each other in the case where the paper sheet is discharged from the other side of the belts. Of course, both sides of the paper sheet are brought into contact with the belts. 
     Therefore, the paper sheet fed between the third one-side transmission member  61   c  and the third other-side transmission member  62   c  which are rotated in the cross state can be discharged while the left and right sides are switched. 
     Explaining the operation in more detail, if the first one-side rotating member  61   a  of the one-side redirecting member  61  is rotated, the third one-side transmission member  61   c  which is brought into contact with one side of the paper sheet is rotated, with the third one-side transmission member  61   c  being interposed between the first one-side rotating member  61   a  and the second one-side rotating member  61   b.    
     In this instance, the other-side redirecting member  62  operates with the one-side redirecting member  61 , and the third other-side transmission member  62   c  is rotated in the state in which it is brought into contact with the other side of the paper sheet. 
     The first other-side rotating member  62   a  and the second other-side rotating member  62   b  which correspond to the first one-side rotating member  61   a  and the second one-side rotating member  61   b  are installed to the housing  10  in the state in which the first other-side rotating member  62   a  is perpendicular to the second other-side rotating member  62   b . Accordingly, the third one-side transmission member  61   c  and the third other-side transmission member  62   c  are rotated in the cross state. 
     In this instance, the paper sheet can be transferred, while the left and right sides are switched by the third one-side transmission member  61   c  and the third other-side transmission member  62   c  which are rotated in the approximately cross state. 
     As the paper sheet facing downwardly by the first sorting member  50  is fed into the third one-side transmission member  61   c  and the third other-side transmission member  62   c , a moving direction of the paper sheet is switched to face downwardly. The left and right sides of the paper sheet moving downwardly by the third one-side transmission member  61   c  and the third other-side transmission member  62   c  which are rotated in the cross state are switched. Specifically, after the left and right sides of the paper sheet are switched, the paper sheet is fed to the upper portion of the second sorting member  70  which will be described later. 
     As illustrated in  FIG. 8 , the third one-side transmission member  61   c  and the third other-side transmission member  62   c  are formed to have a different length. Specifically, if the third other-side transmission member  62   c  is shorter than the third one-side transmission member  61   c , a spaced length L 2  between the first other-side rotating member  62   a  and the third other-side transmission member  62   c  is shorter than a spaced length L 1  between the first one-side rotating member  61   a  and the second one-side rotating member  61   b.    
     Since the first other-side rotating member  62   a  and the second other-side rotating member  62   b  of the other-side redirecting member  62  do not interfere with the first one-side rotating member  61   a  and the second one-side rotating member  61   b  of the one-side redirecting member  61 , the third other-side transmission member  62   c  of the shorter length is easily brought into contact with the third one-side transmission member  61   c  having the relatively long length. 
     If the third one-side transmission member  61   c  and the third other-side transmission member  62   c  are rotated in the contact state, the frictional force on both sides of the paper sheet is increased, so that the paper sheet is easily transferred. 
     As illustrated in  FIGS. 9 and 11 , the paper sheet redirecting unit  60  has a redirecting guide  67  to guide the paper sheet which is redirected by the one-side redirecting member  61  and the other-side redirecting member  62 . The redirecting guide  67  may be made of a plate of which one surface is twisted from one end to the other end. The twisted plates are provided to both sides of the paper sheet redirecting unit  60  to guide both sides of the redirecting paper sheet. 
     Since the redirecting guides  67  are respectively provided to the one-side redirecting member  61  and other-side redirecting member  62 , both sides of the paper sheet redirected by the one-side redirecting member  61  and the other-side redirecting member  62  are supported and guided, thereby preventing the paper sheet from wrinkling or folding in the process of redirecting the paper sheet. Therefore, the paper sheet can be redirected in the state in which it fully spreads. 
     As illustrated in  FIGS. 10 and 11 , the paper sheet redirecting unit  60  has the one-side redirecting member  61  and an other-side redirecting member  62  which is different from the above other-side redirecting member  62 . 
     Since the one-side redirecting member  61  is substantially identical to the above-described one-side redirecting member  61 , the detailed description will be omitted herein. 
     The other-side redirecting member  62  consists of a plurality of guide rollers which are brought into contact with the outer peripheral surface of the third one-side transmission member  61   c  and are rotated by the rotation of the third one-side transmission member  61   c.    
     The guide rollers are installed to the housing  10  to guide the transport of the paper sheet in such a way that the guide rollers are able to idle in the state in which the guide rollers are separated at upper, lower and middle portions of the third one-side transmission member  61   c.    
     In addition, since the guide rollers are driven gears of a simple structure, and are respectively installed to the housing  10 , it is possible to easily and conveniently carry out mounting and demounting work. 
     As described above, the paper sheet horizontally transferred is redirected in a vertical direction by the paper sheet redirecting unit  60 , and then is guided to the downward direction, so that the paper sheet can be sorted to the left or right side of the housing  10  by the second sorting member  70  which will be described later. 
     As illustrated in  FIGS. 12 to 14 , the paper sheet redirecting unit  60  has a one-side transport member  65  which is rotated by the rotating force of the one-side redirecting member  61  to transfer the paper sheet transferred by the third one-side transmission member  61   c  and the third other-side transmission member  62   c  to the discharge hopper  12  provided to one side of the housing  10 , and an other-side transport member  66  which is rotated by the rotating force of the other-side redirecting member  62  to transfer the paper sheet transferred by the third one-side transmission member  61   c  and the third other-side transmission member  62   c  to the discharge hopper  12  provided to the other side of the housing  10 . 
     The one-side transport member  65  has a one-side guide plate  65   a  facing the discharge hopper  12  provided to one side of the housing  10 , a one-side rotating portion  65   b  which is rotatably installed to the housing  10  in a state of being adjacent to the one-side guide plate  65   a  to transfer the paper sheet to the discharge hopper  12  provided to one side of the housing  10 , and a one-side transmission portion  65   c  which is interposed between the one-side rotating portion  65   b  and the one-side redirecting member  61  to transmit the power from the other-side redirecting member  62  to the one-side rotating portion  65   b.    
     The one-side guide plate  65   a  may be formed to have a top flat surface so that the paper sheet is able to slide thereon. 
     The one-side rotating portion  65   b  may be a roller with a roller shaft protruding toward both sides. In this instance, the one-side rotating portion  65   b  is spaced apart from the one-side guide plate  65   a . Therefore, the one-side rotating portion  65   b  can prevent the paper sheet guided by the one-side guide plate  65   a  from floating and leaving outside. 
     The one-side transmission portion  65   c  may be a belt interposed between the roller shaft of the one-side rotating portion  65   b  and the second one-side rotating member  61   b  of the one-side redirecting member  61 . Alternatively, the one-side transmission portion  65   c  may be a pinion which is simultaneously meshed with a gear provided on the roller shaft of the one-side rotating portion  65   b  and a gear provide don the one-side redirecting member  61 . 
     The one-side rotating portion  65   b  rotates with other roller which is adjacent to the one-side guide plate  65   a , to transfer the paper sheet to the one-side guide plate  65   a . Also, the one-side rotating portion  65   b  may be positioned adjacent to the one-side guide plate  65   a  to slide and transfer the paper sheet to the one-side guide plate  65   a.    
     If the one-side redirecting member  61  rotates, the one-side transmission portion  65   c  is driven to rotate the one-side rotating portion  65   b , and thus the paper sheet is slid on the one-side guide plate  65   a  by the rotation of the one-side rotating portion  65   b , so that the paper sheet is transferred to the discharge hopper  12  provided to one side of the housing  10 . 
     The other-side transport member  66  has an other-side guide plate  66   a  facing the discharge hopper  12  provided to the other side of the housing  10 , an other-side rotating portion  66   b  which is rotatably installed to the housing  10  in a state of being adjacent to the other-side guide plate  66   a  to transfer the paper sheet to the discharge hopper  12  provided to the other side of the housing  10 , and an other-side transmission portion  66   c  which is interposed between the other-side rotating portion  66   b  and the other-side redirecting member  62  to transmit the power from the other-side redirecting member  62  to the other-side rotating portion  66   b.    
     The other-side rotating portion  66   b  may be a roller, and the other-side transmission portion  66   c  may be a belt interposed between the one-side rotating portion  65   b  and the second one-side rotating member  61   b  of the one-side redirecting member  61 . 
     The other-side transport member  66  is provided to be symmetrical to the one-side transport member  65 , thereby transfer the paper sheet to the discharge hopper  12  provided to the other side of the housing  10 . 
     The one-side transport member  65  and the other-side transport member  66  are provided to the middle portion of the housing  10  in a symmetrical relation to respectively transfer the paper sheet sorted by the second sorting member  70 , which will be described, to the discharge hoppers  12  provided to both sides of the housing  10 . 
     The second sorting member  70  is provided to one side of the paper sheet redirecting unit  60 , and is operated according to the discrimination of the sensing member  40  to sort the paper sheets transferred by the paper sheet redirecting unit  60  so that the paper sheets are respectively sorted to the discharge hoppers  12  provided to both sides of the housing  10 . The second sorting member  70  has a second sorter  71  and a second sorter driving member  72 . 
     Since the second sorter  71  and the second sorter driving member  72  are substantially identical to the above-described first sorter  51  and the first sorter driving member  52 , its detailed description will be omitted herein. 
     The second sorter  71  is rotatably installed to the housing  10  in such a way that it faces upwardly from the lower portion of the paper sheet redirecting unit  60 . The second sorter  71  turns to the right or the left by operation of the second sorter driving member  72 . 
     Accordingly, if a sharp end of the second sorter  71  faces the left by operation of the second sorter  71  and then the second sorter  71  is fixed in an inclined state, the paper sheet to be discharged from the paper sheet redirecting unit  60  is guided to the other side along the guide surface. If the second sorter  71  rotates in the counterclockwise direction and thus the sharp end of the second sorter  71  faces the right, the paper sheet to be discharged from the paper sheet redirecting unit  60  is guided to the left side along the other guide surface. Specifically, as the second sorter  71  rotates in both directions, the sorted paper sheets can be respectively guided to the discharge hoppers  12  provided to both sides of the housing  10 . 
     The operation of the present invention will now be described. 
     First, if the paper sheet is fed through the inlet hopper  11  of the housing  10 , the paper sheet is fed to the transport member  30  by the feeding member  20 . The transport member  30  transfers the paper sheet to the inner space of the housing  10 . 
     The sensing member  40  detects the counterfeit bill, the type or the damaged banknote among the paper sheets transferred. A counting sensor  80  counts the number of the paper sheets transferred by the transport member  30 . 
     The first sorting member  50  transfers the paper sheet transferred by the transport member  30  toward the discharge hoppers  12  provided to the front side of the housing  10  or the lower portion of the housing  10 . 
     The paper sheet sorted by the first sorting member  50  is discharged to the discharge hopper  12  provided to the front side of the housing  10 , and the remaining paper sheets are sorted by the first sorting member  50  and then are moved to the lower portion of the housing  10  and then the paper sheet redirecting unit  60 . 
     The paper sheet redirecting unit  60  drags the paper sheets down so that the front end of the paper sheet to be fed, in the state in which both ends look at the both sides of the housing  10 , faces downwardly, and then in the state both ends of the paper sheet, and then transfers the paper sheet to the lower portion of the housing while redirecting both ends of the paper sheet toward the front and back of the housing  10 . In this instance, the paper sheet to be redirected may be fed to the upper portion of the second sorting member  70  in a vertical state. 
     The second sorting member  70  sorts the paper sheet transferred toward the left side or the right side. Specifically, the paper sheet to be sorted is respectively discharged to the discharge hoppers  12  provided to the left side and the right side of the housing  10 . 
     As described above, since the direction of the paper sheet is switched from the horizontal state to the vertical state by the paper sheet redirecting unit  60 , the left and right directions of the paper sheet is switched to the forward and rearward directions, which can be correctly sorted to the left and right sides by the second sorting member  70 . 
     Also, if the number of the paper sheets or the type of the paper sheet is set by a controller  90 , the paper sheets which are sorted by the set number or by the set type can be discharged to the respective discharge hoppers  12 . 
     As described above, since the present invention is configured to discharge the paper sheets to the front side or both sides of the housing, the whole volume thereof can be minimized, and it is possible to dust coming from the paper sheet to be discharged from being dispersed in front of the housing. 
     As illustrated in  FIGS. 15 and 16 , the present invention includes the counting sensor  80  which is provided to one side of the transport member  30  to count the number of paper sheets to be transferred by the transport member  30 , and the controller  90  to recognize the paper sheets to be counted by the counting sensor  80  and control the first sorting member  50  and the second sorting member  70  according to the discrimination of the sensing member  40 . 
     The counting sensor  80  can count the number of paper sheets to be transferred by the transport member  30 . 
     The controller  90  can control the first sorting member  50  and the second sorting member  70  according to the discrimination of the sensing member  40 , and can recognize the number of paper sheets to be counted by the counting sensor  80 . Also, the controller can be configured to control the feeding member  20 , the transport member  30 , and the paper sheet redirecting unit  60 . The controller  90  may be a circuit board equipped with programmable IC chips and electronic components. 
     The controller  90  has a paper-sheet-numbers input unit  91  for inputting the number of paper sheets, a paper-sheet-numbers recognizing unit  92  which corresponds to the number of paper sheets inputted by the paper-sheet-numbers input unit  91 , by the counting sensor  80 , a discharge hopper selecting unit  93  for selecting the discharge hopper of the housing  10 , and a sorting member operating unit  94  for operating the first sorting member  50  and the second sorting member  70  to sort the paper sheets by the input number and to discharge the paper sheet to the discharge hopper  12  of the housing  10  which is selected by the discharge hopper selecting unit  93 , if the number of paper sheets inputted by the paper-sheet-numbers input unit  91  is identical to the number of paper sheets recognized by the paper-sheet-numbers recognizing unit  92 . 
     For example, if 10, 20 and 70 paper sheets are inputted by the paper-sheet-numbers input unit  91 , and the discharge hopper  12  provided to the front side of the housing  10 , the discharge hopper  12  provided to one side of the housing  10 , and the discharge hopper  12  provided to the other side of the housing  10  are selected by the discharge hopper selecting unit  93 , the sorting member operating unit  94  operates the first sorting member  50  and the second sorting member  70 , so that 10 paper sheets are discharged to the discharge hopper  12  provided to the front side of the housing  10 , 20 paper sheets are discharged to the discharge hopper  12  provided to one side of the housing  10 , and 70 paper sheets are discharged to the discharge hopper  12  provided to the other side of the housing  10 . 
     Also, the controller  90  has a paper-sheet-type input unit  95  to input the type of paper sheet, and a paper-sheet-type recognizing unit  96  to recognize the paper sheet corresponding to the type of paper sheets inputted in the controller by the paper-sheet-type input unit  95  through the sensing member  40 . The sorting member operating unit  94  can be set to operate the first sorting member  50  and the second sorting member  70  so that the paper sheets recognized by the paper-sheet-type recognizing unit  96  are sorted by type and transferred to the discharge hoppers  12  selected by the discharge hopper selecting unit  93 . 
     The paper-sheet-type input unit  95  can input any one of the counterfeit bill, the type and the damaged banknote which are types of paper sheets in the controller. 
     For example, if the types of paper sheets are inputted as a 1000-won bill, a 5000-won bill and a 10000-won bill by the paper-sheet-type input unit  95 , and the discharge hopper selecting unit  93  selects the discharge hopper  12  provided to the front side of the housing  10 , the discharge hopper  12  provided to one side of the housing  10 , and the discharge hopper  12  provided to the other side of the housing  10 , 1000-won paper sheets are discharged to the discharge hopper  12  provided to the front side of the housing  10 , 5000-won paper sheets are discharged to the discharge hopper  12  provided to one side of the housing  10 , and 10000-won paper sheets are discharged to the discharge hopper  12  provided to the other side of the housing  10 . 
     The controller  90  can stop the operation of the feeding member  20  if the sorting member operating unit  94  recognizes the fact in that the paper sheets sorted by type are sorted by the input number and then are respectively discharged. Accordingly, if the paper sheets are discharged to the discharge hopper  12  by the input number, the feeding member  20  is stopped, thereby preventing the sorted paper sheets from being mixed with other paper sheets. 
     As described above, since the present invention is configured to discharge the paper sheets to the front side or both sides of the housing, the whole volume thereof can be minimized, and it is possible to dust coming from the paper sheet to be discharged from being dispersed in front of the housing. Therefore, the present invention is very useful to be applied to a paper sheet processing unit, such as a paper sheet ATM or a paper sheet counter.
