Definitions
- the present invention relates to a paper-sheet counting machine adapted for counting paper sheets, such as banknotes, checks and the like.
- a banknote counting machine disclosed in JP2600100Y2 is provided for setting a plurality of banknotes in a stacked condition on a placing unit (e.g., a hopper), then feeding and inserting each banknote located at the lowest position of the banknotes into a space between a pair of gate units, one by one, by using a feeding unit, such as a feed roller or the like, provided at a bottom part of the placing unit, thereby separating such banknotes, one by one, and feeding each separated banknote downward, via a passage, and further feeding it into a space between two vanes of a stacking wheel located in the middle of the passage.
- a placing unit e.g., a hopper
- each banknote received between the two vanes is thrown off therefrom, downward onto a stacking unit, while being turned round with rotation of the stacking wheel, and then arranged in the stacking unit.

- each paper sheet P is stacked in the stacking unit 26, while falling down forward from the back (or rightward from the left as shown in Fig. 1 and the like). Therefore, there is a risk that the dust accumulated in the stacking unit 26 and the like and/or dust attached to each paper sheet P may be blown out toward the operator, via the opening in the front face of the stacking unit 26.
- this shutter 40 can serve to suppress the blowing out of the dust toward the operator with rotation of the stacking wheel 28.

- the paper-sheet counting machine 10 includes a control unit 70.
- This control unit 70 serves to control each component of the paper-sheet counting machine 10. More specifically, this control unit 70 is connected with each of the feeding unit 16, transport unit 22, recognition and counting unit 24, stacking-wheel drive unit 29 for driving the stacking wheel 28, diverter 32 and shutter drive unit 50 for driving the shutter 40.
- the recognition and counting result on each paper sheet P recognized by the recognition and counting unit 24 is sent to the control unit 70, while the control unit 70 sends a command signal to each of the feeding unit 16, transport unit 22, stacking-wheel drive unit 29, diverter 32, shutter drive unit 50 and the like, in order to control such components.
- control unit 70 is connected with each of the placing-unit-residue detection sensor 60, reject-unit paper-sheet detection sensor 62, paper-sheet tracking detection sensor 64, diversion timing sensor 66 and stacking-unit paper-sheet detection sensor 68, in order to receive each detection result from such sensors.
- control unit 70 is connected with the shutter-closing detection sensor 54a and shutter-opening detection sensor 54b.
- the control unit 70 receives information that the shutter 40 is located in the closing position shown in Fig. 3 or information that the shutter 40 is located in the opening position shown in Fig. 4 , from the shutter-closing detection sensor 54a or shutter-opening detection sensor 54b.
- control unit 70 is connected with a display unit 72 and an operation unit 74.
- the display unit 72 and operation unit 74 are respectively provided to a front face of the casing 12.
- the condition under which the paper sheets P are handled by the paper-sheet counting machine 10, more specifically the information on the number or the like of the paper sheets P counted by the recognition and counting unit 24, is displayed on the display unit 72. Further, the operator can input various commands to the control unit 70 via the operation unit 74.
- the operator places the paper sheets P to be counted, on the placing unit 14, in the stacked condition.
- the with-shutter-operation mode means a mode in which the control unit 70 controls the shutter drive unit 50, in order to open and close the opening in the front face of the stacking unit 26 by using the shutter 40.
- the without-shutter-operation mode means a mode in which the control unit 70 does not control the shutter drive unit 50 and thus the opening and closing operation for the opening in the front face of the stacking unit 26 is not performed by the shutter 40.
- the paper sheets P placed on the placing unit 14 are counted and the so-counted paper sheets P are fed to the stacking unit 26, in a state in which the shutter 40 is kept located in the opening position shown in Fig. 2 , or in a state in which the opening in the front face of the stacking unit 26 is kept opened.
- the operation shown in the flow charts of Figs. 6 through 8 is performed. Namely, in an initial state of this operation, the shutter 40 is retreated from the opening in the front face of the stacking unit 26 (i.e., the shutter 40 is located in the opening position shown in Fig. 2 ), and thus the opening in the front face of the stacking unit 26 is opened (STEP 1 of Fig. 6 ).
- control unit 70 serves to selectively perform a batch process mode, in which the counting unit 24 counts paper sheets P by the batch number, the batch number being instructed to the control unit 70 via the operation unit 74. Then, as shown in STEP 2 of Fig. 6 , whether or not the batch process mode is performed is selected by the operator via the operation unit 74. If the batch process mode is selected to be performed by the operator, the operation, as is shown in the flow charts of Figs. 7 and 8 described later, is performed. The operation of the paper-sheet counting machine 10 associated with this batch process mode will be described later. Meanwhile, if the batch process mode is not selected to be performed, the counting process for the paper sheets P, as will be described below, is performed in accordance with the flow chart of Fig. 6 .
- the control unit 70 controls the shutter drive unit 50 to drive the shutter 40 to close the opening in the front face of the stacking unit 26 (STEP 3 of Fig. 6 ). More specifically, the shutter drive unit 50 rotates the rotation shaft 51 in the anticlockwise direction in Fig. 4 (i.e., in the direction indicated by the arrow), from the state shown in Fig. 4 . As a result, the circular linking member 44b provided to the plate member 44 is no longer pressed upward in Fig. 4 by the cam 52. Thus, the plate member 44 is rotated, by the contraction force of the spring 46, in the anticlockwise direction in Fig. 4 , about the shaft 44a, from the state shown in Fig.
- the shutter support unit 42 attached to the plate member 44 is also rotated in the anticlockwise direction in Fig. 4 , about the shaft 44a, from the state shown in Fig. 4 .
- the shutter support unit 42 is moved from the position shown in Fig. 4 to the position shown in Fig. 3 .
- the shutter 40 is moved from the opening position as shown in Fig. 2 to the closing position as shown in Fig. 1 , thus closing the opening in the front face of the stacking unit 26.
- the timing on which the opening in the front face of the stacking unit 26 is closed by the shutter 40 is set, as the timing before the counting process for the paper sheets P by the recognition and counting unit 24 is started, i.e., the timing before the counting process for the paper sheets P is started or timing substantially the same as the start of the counting process for the paper sheets P. If the opening in the front face of the stacking unit 26 is closed by the shutter 40 at substantially the same timing as the start of the counting process for the paper sheets P, the time required for the entire process for the paper sheets P in the paper-sheet counting machine 10 can be reduced.
- the control unit 70 may control the shutter drive unit 50 to drive the shutter 40 to start closing the opening in the front face of the stacking unit 26, at the same time as the start of the counting process for the paper sheets P by the recognition and counting unit 24, thereby to close the opening in the front face of the stacking unit 26, while counting the paper sheets P.
- the opening in the front face of the stacking unit 26 is closed, in a period of time during which the paper sheets P are counted. Therefore, the time required for the entire process for the paper sheets P in the paper-sheet counting machine 10 can be reduced, as compared with the case in which the paper sheets P are counted after the opening in the front face of the stacking unit 26 is closed.
- the paper sheets P are fed to the transport unit 22 in the casing 12, one by one, by the feeding unit 16, successively, from the paper sheet P located at the lowermost layer, and then transported by the transport unit 22.
- the recognition and counting process for the paper sheets P is performed by the recognition and counting unit 24.
- each paper sheet P recognized, as the normal paper sheet, by the recognition and counting unit 24 is fed to the stacking unit 26 via the diverter 32. More specifically, the paper sheets P are fed, one by one, from the transport unit 22 to the stacking wheel 28. Then, the stacking wheel 28 receives each paper sheet P fed from the transport unit 22, between the two vanes 28a thereof.
- each paper sheet P received between the two vanes 28a is fed into the stacking unit 26.
- the paper sheets P can be arranged in the stacking unit 26, by the stacking wheel 28.
- the opening in the front face of the stacking unit 26 is closed by the shutter 40, the operator cannot take out the paper sheets P stacked in the stacking unit 26.
- each paper sheet that is not recognized as the normal paper sheet by the recognition and counting unit 24 and each paper sheet that cannot be recognized by the recognition and counting unit 24 are respectively fed, as the reject paper sheets P', to the reject unit 30, by the diverter 32. Since the opening is provided in the front face of the reject unit 30, the operator can take out the reject paper sheets P' stacked in the reject unit 30, via this opening.
- the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the reject paper sheets P', respectively taken out form the reject unit 30, on the placing unit 14.
- the control unit 70 controls the shutter drive unit 50 to move the shutter 40 to the opening position shown in Fig. 2 from the closing position shown in Fig. 1 .
- the opening in the front face of the stacking unit 26 is opened (STEP 8 of Fig. 6 ).
- the operator takes out the paper sheets P stacked in the stacking unit 26 via the opening in the front face of the stacking unit 26 (STEP 9 of Fig. 6 ), and then starts again the counting process for the paper sheet P, via the operation unit 74 (STEP 10 of Fig. 6 ). In this way, the counting process for the paper sheets P in the paper-sheet counting machine 10 is started again.
- the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator takes out the paper sheets P form the stacking unit 26.
- the control unit 70 controls the shutter drive unit 50 to drive the shutter 40 to close the opening in the front face of the stacking unit 26 (STEP 3 of Fig. 6 ).
- the placing-unit-residue detection sensor 60 detects whether or not there are some paper sheets P remaining on the placing unit 14 (STEP 11 of Fig. 6 ).
- the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placing unit 14, this detection result is displayed on the display unit 72.
- the reject-unit paper-sheet detection sensor 62 detects whether or not there are some reject paper sheets P' remaining in the reject unit 30 (STEP 12 of Fig. 6 ).
- the reject-unit paper-sheet detection sensor 62 detects that there are some reject paper sheets P' remaining in the reject unit 30, this detection result is displayed on the display unit 72. Thereafter, the operator takes out the reject paper sheets P' from the reject unit 30 (STEP 15 of Fig. 6 ), sets again such paper sheets P' on the placing unit 14, and then starts again the counting process for the paper sheets P, via the operation unit 74 (STEP 16 of Fig. 6 ). In this way, the counting process for the paper sheets P in the paper-sheet counting machine 10 is started again.
- the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the reject paper sheets P', respectively taken out form the reject unit 30, on the placing unit 14.
- the counting process for the paper sheets P in the paper-sheet counting machine 10 is ended (STEP 13 of Fig. 6 ).
- the control unit 70 controls the shutter drive unit 50 to move the shutter 40 to the opening position shown in Fig. 2 from the closing position shown in Fig. 1 .
- the opening in the front face of the stacking unit 26 is opened (STEP 14 of Fig. 6 ).
- the operator takes out the paper sheets P stacked in the stacking unit 26, via the opening in the front face of the stacking unit 26. In this way, the operation of the paper-sheet counting machine 10, in the case of not performing the batch process mode, is completed.
- the control unit 70 controls the shutter drive unit 50 to drive the shutter 40 to close the opening provided in the front face of the stacking unit 26, before the counting process for the paper sheets P is started by the recognition and counting unit 24. Therefore, the opening in the front face of the stacking unit 26 is closed by the shutter 40, during the period of time in which the counting process for the paper sheets P is performed by the recognition and counting unit 24, thereby preventing the dust accumulated in the casing 12 of the paper-sheet counting machine 10 and/or dust attached to each paper sheet from being blown out toward the operator.
- the control unit 70 controls the shutter drive unit 50 to retreat the shutter 40 from the opening provided in the front face of the stacking unit 26 to open the opening.
- the control unit 70 controls the shutter drive unit 50 to retreat the shutter 40 from the opening provided in the front face of the stacking unit 26 to open the opening.
- control unit 70 may serve to open the opening in the front face of the stacking unit 26, once the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placing unit 14, irrespectively of whether or not there are some reject paper sheets P' remaining in the reject unit 30.
- interval of time between the time the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placing unit 14 and the time the control unit 70 controls the shutter drive unit 50 to retreat the shutter 40 from the opening in the front face of the stacking unit 26, may be optionally altered, by the operator, with appropriate settings via the operation unit 74. In this case, the operator can optionally select the order of priority, between the dustproof and/or soundproofing in the paper-sheet counting machine 10 and the reduction of the time required for handling the paper sheets P.
- the control unit 70 serves to drive the shutter 40 to keep closing the opening provided in the front face of the stacking unit 26.
- the control unit 70 may control the shutter drive unit 50 to retreat the shutter 40 from the opening in the front face of the stacking unit 26 to open the opening.
- the opening in the front face of the stacking unit 26 can be opened more rapidly, thereby to substantially reduce the time required for the entire process for the paper sheets P.
- interval of time between the time the paper-sheet tracking detection sensor 64 detects the paper sheet P, with which the stacking unit 26 will be full up upon receiving thereof, and the time the control unit 70 controls the shutter drive unit 50 to retreat the shutter 40 from the opening in the front face of the stacking unit 26, may be optionally altered, by the operator, with proper settings via the operation unit 74.
- the operator can optionally select the order of priority, between the dustproof or soundproofing in the paper-sheet counting machine 10 and the reduction of the time required for handling the paper sheets P.
- the paper-sheet tracking detection sensor 64 is provided in such a position that interval of time between the time one paper sheet P is detected by the paper-sheet tracking detection sensor 64 and the time this paper sheet P is fed to the stacking unit 26, is substantially matched with the time required for the shutter 40 to be moved from the closing position (see Fig. 1 ) in which the opening in the front face of the stacking unit 26 is closed to the opening position (see Fig. 2 ) in which the opening is opened. Therefore, when the paper-sheet tracking detection sensor 64 detects a certain paper sheet, with which the stacking unit 26 will be full up upon receiving this paper sheet P fed thereto, and then this paper sheet P actually reaches the stacking unit 26, the opening in the front face of the stacking unit 26 is just opened. Thus, the operator can take out a batch of the paper sheets P stacked in the stacking unit 26, just after the certain paper sheet P reaches the stacking unit 26.
- the control unit 70 compares the batch number inputted to the control 70 via the operation unit 74 with a preset number (e.g., ten) of the paper sheets (STEP 21 of Fig. 7 ). If the batch number inputted to the control unit 70 is equal to or greater than the preset number, the operation, shown in the flow chart of Fig. 8 described later, is performed. The operation of the paper-sheet counting machine 10 in the batch process mode will be described later.
- a preset number e.g., ten
- control unit 70 serves to keep the shutter 40 retreated from the opening in the front face of the stacking unit 26, thereby to keep this opening opened. Thereafter, the counting process for the paper sheets P is performed, as will be described below.
- the paper sheets P respectively placed, in the stacked condition, on the placing unit 14 are fed, one by one, to the transport unit 22 in the casing 12, by the feeding unit 16, successively, from the paper sheet P located at the lowermost layer, and then transported by the transport unit 22.
- the paper sheets P are recognized and counted by the recognition and counting unit 24.

- the paper sheets P are arranged in the stacking unit 26 by the stacking wheel 28.
- each paper sheet that is not recognized as the normal paper sheet by the recognition and counting unit 24 and each paper sheet that cannot be recognized by the recognition and counting unit 24 are respectively fed, as the reject paper sheets P', to the reject unit 30, by the diverter 32. Since the opening is provided in the front face of the reject unit 30, the operator can take out such reject paper sheets P' stacked in the reject unit 30, via this opening.
- the maximum number of the reject paper sheets P' that can be stored in the reject unit 30 is set, in advance. In this case, when the number of the reject paper sheets P' fed to the reject unit 30 reaches the preset maximum number of the reject paper sheets P' that can be stored therein, or when the reject unit 30 is full up with the reject paper sheets P', during the counting process for the paper sheets P in the paper-sheet counting machine 10 (STEP 22 of Fig. 7 ), this condition of the reject unit 30 is displayed on the display unit 72, and the counting process for the paper sheets P in the paper-sheet counting machine 10 is once stopped. Thereafter, the operator takes out the reject paper sheets P' from the reject unit 30 (STEP 23 of Fig.
- the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the reject paper sheets P', respectively taken out form the reject unit 30, on the placing unit 14.
- the operator takes out the reject paper sheets P' from the reject unit 30 (STEP 29 of Fig. 7 ), sets again such reject paper sheets P' on the placing unit 14, and then starts again the counting process for the paper sheets P, via the operation unit 74 (STEP 30 of Fig. 7 ).
- the counting process for the paper sheets P in the paper-sheet counting machine 10 is started again.
- the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the reject paper sheets P', respectively taken out form the reject unit 30, on the placing unit 14.
- the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placing unit 14, and when the reject-unit paper-sheet detection sensor 62 detects that there is no reject paper sheet P' remaining in the reject unit 30, if the operator inputs a command for terminating the counting process for the paper sheets P, to the control unit 70, via the operation unit 74 (STEP 31 of Fig. 7 ), the counting process for the paper sheets P in the paper-sheet counting machine 10 is ended (STEP 26 of Fig. 7 ). At this time, since the opening in the front face of the stacking unit 26 is kept opened, the operator can take out the paper sheets P stacked in the stacking unit 26, via the opening in the front face of the stacking unit 26.
- the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placing unit 14, and when the reject-unit paper-sheet detection sensor 62 detects that there is no reject paper sheet P' remaining in the reject unit 30, if the operator places additional paper sheets P on the placing unit 14 (STEP 32 of Fig. 7 ), and then starts again the counting process for the paper sheets P, via the operation unit 74 (STEP 33 of Fig. 7 ), the counting process for the paper sheets P in the paper-sheet counting machine 10 is restarted. In place of the operator starting again the counting process for the paper sheets, via the operation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the additional paper sheets P on the placing unit 14.
- the control unit 70 when the control unit 70 performs the counting process for the paper sheets P in the batch process mode, and when the batch number of the paper sheets P inputted to the control unit 70 is smaller than the preset number, the control unit 70 serves to retreat the shutter 40 from the opening provided in the front face of the stacking unit 26 to open this opening. Namely, in the case the batch number inputted to the control unit 70 is relatively small, if the opening and closing operation of the shutter 40 is performed for each batch process, the time required for the entire process for the paper sheets P becomes considerably long. Therefore, in this case, by keeping the opening opened in the front face of the stacking unit 26, the time required for the entire process for the paper sheets P can be reduced.
- control unit 70 controls the shutter drive unit 50 to drive the shutter 40 to close the opening in the front face of the stacking unit 26 (STEP 41 of Fig. 8 ). Then, the counting process for the paper sheets P is performed, as will be described below.

- each paper sheet that is not recognized as the normal paper sheet by the recognition and counting unit 24, and each paper sheet that cannot be recognized by the recognition and counting unit 24 are respectively fed, as the reject paper sheets P' , to the reject unit 30, via the diverter 32.

In place of the operator starting again the counting process for the paper sheets, via the operation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the additional paper sheets P on the placing unit 14.
- the control unit 70 controls the shutter drive unit 50 to drive the shutter 40 to keep closing the opening provided in the front face of the stacking unit 26. Namely, in this case, as shown in the STEP 53 and STEP 54 of Fig.
- this paper-sheet counting machine 10 can prevent the operator from misunderstanding that the batch process has been properly performed and thus the number of the paper sheets P stacked in the stacking unit 26, at this point of time, is correctly corresponding to the batch number. Accordingly, this paper-sheet counting machine 10 can securely prevent the operator from mistakenly taking out the paper sheets P from the stacking unit 26.

Additionally, the shutter-closing detection sensor 54a and shutter-opening detection sensor 54b are respectively fixed in position, in the vicinity of the sixth gear 86. Each of such shutter-closing detection sensor 54a and shutter-opening detection sensor 54b is composed of the optical sensor. In this case, when the shutter 40 is located in the closing position, the position of the first notched portion 86b of the sixth gear 86 is substantially matched with the position of the shutter-closing detection sensor 54a. Therefore, the detection of the first notched portion 86b of the sixth gear 86 by the shutter-closing detection sensor 54a indicates the detection of the shutter 40 located in the closing position.
- the position of the second notched portion 86c of the sixth gear 86 is substantially matched with the position of the shutter-opening detection sensor 54b. Therefore, the detection of the second notched portion 86c of the sixth gear 86 by the shutter-opening detection sensor 54b indicates the detection of the shutter 40 located in the opening position.

- the driving force exerted from the shutter drive unit 50 is transmitted, from the first gear 80, through the second gear 81, third gear 82, fourth gear 83, torque limiter 84 and fifth gear 85, up to the sixth gear 86, as such the sixth gear 86 is rotated in the clockwise direction in Fig. 9 about the shaft 86a. Therefore, the shutter support unit 42 attached to the sixth gear 86 is also rotated in the clockwise direction in Fig. 9 about the shaft 86a.
- the shutter 40 is moved from the closing position as shown in Fig. 1 to the opening position as shown in Fig. 2 .

- the torque limiter 84 is provide between the shutter support unit 42 for supporting the shutter 40 and the shutter drive unit 50. Therefore, in the case the operator moves the shutter 40 downward, by hand, from the closing position shown in Fig. 1 , when the force applied from the operator to the torque limiter 84 is greater than the preset torque, the torque limiter 84 releases the connection between the fourth gear 83 and the fifth gear 85. As such, the fifth gear 85 can be rotated freely relative to the fourth gear 83. Namely, in this case, the torque limiter 84 serves to block the driving force of the shutter drive unit 50 to be transmitted to the shutter 40.
- the operator can move the shutter 40 downward, by hand, from the closing position shown in Fig. 1 , thereby to take out the paper sheets P from the stacking unit 26.
- the torque limiter 84 releases the connection between the fourth gear 83 and the fifth gear 85, thus allowing the fifth gear 85 to be rotated freely relative to the fourth gear 83.
- the torque limiter 84 serves to block the driving force of the shutter drive unit 50 to be transmitted to the shutter 40.

- It is further preferred that the third paper-sheet detection unit is provided in such a position that interval of time between the time the paper sheet is detected by the third paper-sheet detection unit and the time this paper sheet is fed to the stacking unit is substantially matched with the time required for the shutter to be moved from the position for closing the opening provided in the front face of the stacking unit to the position for opening the same opening.
- In the paper-sheet counting machine of the present invention, it is preferred that the control unit performs selectively either one of a with-shutter-operation mode, in which the control unit controls the shutter drive unit to drive the shutter to open and close the opening provided in the front face of the stacking unit, and a without-shutter-operation mode, in which the shutter drive unit is not controlled by the control unit, and thus the opening and closing operation for the opening provided in the front face of the stacking unit is not performed by the shutter.

Of these drawings,
Figs. 1 through 8 are respectively provided for illustrating the paper-sheet counting machine related to the embodiment. More specifically,Figs. 1 and2 are respectively provided for schematically illustrating the internal construction of the paper-sheet counting machine related to the embodiment.Figs. 3 and 4 are respectively provided for illustrating the details of the construction of the shutter, shutter support unit for supporting the shutter, shutter drive unit and the like, respectively provided in the paper-sheet counting machine shown inFig. 1 and the like. The block diagram ofFig. 5 is provided for illustrating one exemplary control system of the paper-sheet counting machine shown inFig. 1 and the like. Each flow chart ofFigs. 6 through 8 illustrates the series of operations, respectively performed by the paper-sheet counting machine shown inFig. 1 and the like. It is noted that the paper-sheet counting machine related to this embodiment is intended for counting the number of the paper sheets, such as the banknotes, checks and the like. - As illustrated in
Figs. 1 and2 , a paper-sheet counting machine 10 includes acasing 12 and aplacing unit 14 adapted for placing thereon a plurality of paper sheets P to be respectively counted, in a stacked condition. Further, this paper-sheet counting machine 10 includes afeeding unit 16 adapted for feeding each paper sheet P located at the lowermost layer of the paper sheets P placed on the placingunit 14 in the stacked condition, one by one, into thecasing 12, and atransport unit 22 adapted for transporting the paper sheets P, respectively fed into thecasing 12 by thefeeding unit 16, one by one. InFigs. 1 and2 , the right side face of thecasing 12 is depicted as the front face thereof, while the left side face of thecasing 12 shows the back face thereof. In addition, a recognition andcounting unit 24 adapted for recognizing and counting the paper sheets P respectively fed into thecasing 12 from the placingunit 14 is provided to thetransport unit 22. For instance, the recognition andcounting unit 24 is composed of a line sensor. - The
feeding unit 16 includes akicker roller 16a provided to be in contact with the surface of one paper sheet P located at the lowermost layer of the paper sheets P placed on the placingunit 14 in the stacked condition, and afeed roller 16b located on the downstream side, in the feeding direction of the paper sheets P, relative to thekicker roller 16a and adapted for feeding the paper sheets P, respectively kicked out by thekicker roller 16a, into thecasing 12. Further, a gate roller (or reverse rotation roller) 16c is provided to be opposed to thefeed roller 16b, with a gate part provided between thefeed roller 16b and thegate roller 16c. Thus, each paper sheet P kicked out by thekicker roller 16a is passed through the gate part and then fed out, one by one, toward thetransport unit 22 in thecasing 12. - The
transport unit 22 is bifurcated into two transport paths at a point located on the downstream side relative to the recognition andcounting unit 24, and one of the two bifurcated transport paths is connected with a stackingunit 26, while the other transport path is connected with areject unit 30. To the stackingunit 26, each paper sheet P that has been recognized as a normal paper sheet by the recognition andcounting unit 24 is fed. An opening is provided in the front face of the stacking unit 26 (i.e., the face of the stackingunit 26 depicted on the right side inFigs. 1 and2 ), such that the operator can take out the paper sheets P respectively stacked in the stackingunit 26, via this opening. - Meanwhile, each paper sheet that is not recognized as the normal paper sheet by the recognition and
counting unit 24 and each paper sheet that cannot be recognized by the recognition andcounting unit 24 are respectively fed to areject unit 30, as reject paper sheets P', by thetransport unit 22. Similarly, one opening is provided in the front face of thereject unit 30, such that the operator can take out the reject paper sheets P' respectively stacked in thereject unit 30, via this opening. - As shown in
Figs. 1 and2 , adiverter 32 is provided at the same point where thetransport unit 22 is bifurcated into the two transport paths. Due to thisdiverter 32, each paper sheet that has been fed from the upstream side of thediverter 32 can be selectively fed to either one of the two bifurcated transport paths. - A stacking
wheel 28 is provided on the back face side (i.e., in a position located on the left side shown inFigs. 1 and2 ) of the stackingunit 26 in thecasing 12. This stackingwheel 28 is configured to be rotated in a clockwise direction inFig. 1 and the like (i.e., the direction indicated by an arrow depicted inFigs. 1 and2 ) about a shaft extending in a substantially horizontal direction orthogonal to the sheet ofFig. 1 and the like. The rotational operation of the stackingwheel 28 is performed by a stacking-wheel drive unit 29 (not shown inFigs. 1 and2 ) that will be described later. In this stackingwheel 28, a plurality ofvanes 28a are provided to extend outward, from an outer circumferential face of thewheel 28, in a direction reverse to the rotation direction of the wheel 28 (i.e., the anticlockwise direction inFig. 1 and the like). More specifically,such vanes 28a are provided to the outer circumferential face of the stackingwheel 28, at an equal interval, as shown inFig. 1 and the like. - The stacking
wheel 28 is configured to be constantly rotated in the clockwise direction inFig. 1 and the like, by the stacking-wheel drive unit 29, during the operation of the paper-sheet counting machine 10, thereby to receive the paper sheets P, respectively fed from thetransport unit 22, one by one. Then, the stackingwheel 28 receives each paper sheet P fed from thetransport unit 22, between the twovanes 28a thereof, and then feeds the paper sheet P received between the twovanes 28a into the stackingunit 26. In this way, the paper sheets P can be fed to the stackingunit 26, one by one, from the stackingwheel 28, as such the plurality of paper sheets P can be stacked in the stackingunit 26. - In the paper-
sheet counting machine 10 of this embodiment, ashutter 40 is provided to close the opening provided in the front face of the stackingunit 26. Thus, the opening in the front face of the stackingunit 26 can be selectively closed by theshutter 40. By a shutter drive unit 50 (not shown inFigs. 1 and2 ) that will be described later and is composed of, for example, a motor, theshutter 40 is moved, between the closing position, as depicted inFig. 1 , in which the opening in the front face of the stackingunit 26 is closed, and the opening position, as depicted inFig. 2 , in which theshutter 40 is retreated from the opening in the front face of the stackingunit 26 to open the opening. Namely, when theshutter 40 is located in the closing position as depicted inFig. 1 , the opening in the front face of the stackingunit 26 is closed, thus preventing the operator from accessing the paper sheets P respectively stacked in the stackingunit 26. Meanwhile, when theshutter 40 is located in the opening position as depicted inFig. 2 , thisshutter 40 is retreated from the opening in the front face of the stackingunit 26, and thus the opening is opened, thereby allowing the operator to access the paper sheets P respectively stacked in the stackingunit 26. - Now, the reason why the
shutter 40 is provided will be described below. In the paper-sheet counting machine 10 including the stackingwheel 28 provided to the stackingunit 26, each paper sheet P is stacked in the stackingunit 26, while falling down forward from the back (or rightward from the left as shown inFig. 1 and the like). Therefore, there is a risk that the dust accumulated in the stackingunit 26 and the like and/or dust attached to each paper sheet P may be blown out toward the operator, via the opening in the front face of the stackingunit 26. However, when theshutter 40 is moved to the closing position, as depicted inFig. 1 , to close the opening in the front face of the stackingunit 26, thisshutter 40 can serve to suppress the blowing out of the dust toward the operator with rotation of the stackingwheel 28. Further, when theshutter 40 is located in the closing position to close the opening in the front face of the stackingunit 26, the unwanted leakage of the sound generated in the paper-sheet counting machine 10, to the outside, can be prevented during the operation of themachine 10. - The
shutter 40 may be composed of a transparent material, such as a plastic material or the like. In this case, even in the case theshutter 40 is located in the closing position in which the opening in the front face of the stackingunit 26 is closed as depicted inFig. 1 , the operator can confirm, with eyes, the stacked condition of the paper sheets P in the stackingunit 26, via theshutter 40 formed of a proper transparent material. - Next, the operation of the
shutter 40 driven by theshutter drive unit 50 will be described in more detail, with reference toFigs. 3 and 4. Figs. 3 and 4 are respectively provided for illustrating the details of the construction of theshutter 40,shutter support unit 42 for supporting theshutter 40,shutter drive unit 50 and the like, respectively provided in the paper-sheet counting machine 10 shown inFig. 1 and the like. More specifically,Fig. 3 is provided for illustrating one operational state corresponding toFig. 1 , in which theshutter 40 closes the opening provided in the front face of the stackingunit 26. Meanwhile,Fig. 4 is provide for illustrating another operational state corresponding toFig. 2 , in which theshutter 40 is retreated from the opening provided in the front face of the stackingunit 26 to open the opening. - As shown in
Fig. 3 and the like, theshutter 40 is supported by theshutter support unit 42, and a substantiallyrectangular plate member 44 is attached to theshutter support unit 42. Ashaft 44a is provided to a central part of theplate member 44, such that theplate member 44 is reciprocated about thisshaft 44a. As such, theshutter 40 supported by theshutter support unit 42 is also reciprocated about theshaft 44a. Further, acircular linking member 44b is attached to one end of theplate member 44 on the opposite side of theshutter 40, such that this linkingmember 44b can be optionally rotated relative to theplate member 44. - Further, an elastic member, more specifically, one
end 46b of aspring 46, is attached to the end of theplate member 44 opposite to the end thereof to which the linkingmember 44b is provided. In this case, theother end 46a of thespring 46 opposite to the oneend 46b thereof attached to theplate member 44 is fixed to an inner face of thecasing 12. Namely, theother end 46a of thespring 46 is fixed in position, while the position of the oneend 46b of thespring 46 attached to the end of theplate member 44 is changed, with the reciprocation movement of theplate member 44 about theshaft 44a. With such configuration, due to contraction force of thespring 46, theshutter 40 is constantly biased from the opening position thereof as depicted inFig. 4 toward the closing position thereof as depicted inFig. 3 . - Further, a
cam 52 is provided to be in contact with the outer circumferential face of thecircular linking member 44b rotatably provided relative to theplate member 44. Thiscam 52 has arotation shaft 51 attached thereto and located in a point eccentric to the central part of thecam 52. Thisrotation shaft 51 is rotated in the anticlockwise direction inFig. 3 and the like (as indicated by an arrow), by theshutter drive unit 50 composed of, for example, the motor or the like. Thus, thecam 52 is also rotated in the anticlockwise direction inFig. 3 and the like (as indicated by the arrow), about therotation shaft 51. With this rotation of thecam 52 about therotation shaft 51, the linkingmember 44b that is in contact with an edge portion of thecam 52 is pressed and pushed upward inFig. 3 (as indicated by another arrow), from the state shown inFig. 3 . Thus, theplate member 44 is rotated in the clockwise direction about theshaft 44a. As such, theshutter support unit 42 attached to theplate member 44 is also rotated in the clockwise direction about theshaft 44a from the state shown inFig. 3 , thus allowing theshutter support unit 42 to be moved to the position shown inFig. 4 from the position shown inFig. 3 . In this way, theshutter 40 is moved to the opening position as depicted inFig. 2 , from the closing position as depicted inFig. 1 . During this operation, thespring 46 is expanded from the state shown inFig. 3 to the state shown inFig. 4 . - However, when the
cam 52 is further rotated about therotation shaft 51, in the anticlockwise direction inFig. 4 (as indicated by an arrow) from the state as shown inFig. 4 , thecircular linking member 44b provided to theplate member 44 is no longer pressed upward inFig. 4 by thecam 52. As such, due to the contraction force of thespring 46, theplate member 44 is rotated in the anticlockwise direction inFig. 4 , about theshaft 44a, from the state shown inFig. 4 . Thus, theshutter support unit 42 attached to theplate member 44 is also rotated in the anticlockwise direction, about theshaft 44a, from the state shown inFig. 4 , and hence returned to the position shown inFig. 3 from the position shown inFig. 4 . In this way, theshutter 40 is returned to the closing position as shown inFig. 1 , from the opening position as shown inFig. 2 . During this operation, thespring 46 is contracted into the state shown inFig. 3 , from the state shown inFig. 4 . - In this way, the
shutter 40 is reciprocated about theshaft 44a by theshutter drive unit 50, between the closing position (seeFigs. 1 and3 ), in which the opening in the front face of the stackingunit 26 is closed, and the opening position (seeFigs. 2 and4 ), in which theshutter 40 is retreated from the opening to open this opening. In the opening position, as shown inFig. 2 and the like, theshutter 40 is located below the stackingwheel 28. Thus, when theshutter 40 is located in the opening position, the dust generated from the stackingwheel 28 and the like can be received by thisshutter 40, thereby preventing such dust being accumulated on an inner bottom face of thecasing 12. - For instance, the time required for the
shutter 40 to be moved from the closing position shown inFig. 1 to the opening position shown inFig. 2 and the time required for theshutter 40 to be moved from the opening position shown inFig. 2 to the closing position shown inFig. 1 are set at 0.5 seconds, respectively. - Further, since the
shutter 40 is biased, toward the closing position as depicted inFig. 3 from the opening position as depicted inFig. 4 , by the contraction force of thespring 46, thisshutter 46 can be moved downward, by hand, from the closing position shown inFig. 3 , against the contraction force of thespring 40. Therefore, theshutter 40 can be retreated, as needed, by hand, from the opening in the front face of the stackingunit 26, even in a period of time during which theshutter 40 is located in the closing position shown inFig. 3 and the paper sheets P are counted by the recognition andcounting unit 24. In this way, the paper sheets P can be taken out from the stackingunit 26. - Further, as described above, the
spring 46 is provided to theshutter 40, and thecam 52 is provided to theshutter drive unit 50, while being engaged with the linkingmember 44b of theplate member 44. In addition, theshutter 40 can be biased toward the closing position (as shown inFig. 3 ) in which the opening in the front face of the stackingunit 26 is closed, by the contraction force of thespring 46, as well as can be retreated from the opening in the front face of the stackingunit 26 toward the opening position (as shown inFig. 4 ) to open the opening, by thecam 52 provided to theshutter drive unit 50. Therefore, this configuration can successfully prevent the finger or the like of the operator from being accidentally nipped and injured by theshutter 40, during the period of time in which theshutter 40 is moved from the opening position shown inFig. 2 to the closing position shown inFig. 1 . This is because, the force used for pressing and moving theshutter 40 toward the closing position is not the driving force exerted from theshutter drive unit 50, but the contraction force of thespring 46. - As shown in
Figs. 3 and 4 , a shutter-closing detection sensor 54a and a shutter-openingdetection sensor 54b are respectively fixed in position in the vicinity of thecam 52. Each of the shutter-closing detection sensor 54a and shutter-openingdetection sensor 54b is composed of an optical sensor. Further, adetection target member 53 to be detected by each of the shutter-openingdetection sensor 54a and shutter-openingdetection sensor 54b is provided to one side face of thecam 52. In this case, as shown inFig. 3 , when the shutter-closing detection sensor 54a detects thedetection target member 53, theshutter 40 is detected to be in the closing position. Meanwhile, when thecam 52 is rotated in the anticlockwise direction about therotation shaft 51, from the state shown inFig. 3 to the state shown inFig. 4 , the shutter-openingdetection sensor 54b detects thedetection target member 53. As a result, theshutter 40 is detected to be in the opening position. - In addition, as shown in
Fig. 1 and the like, various sensors are provided to the paper-sheet counting machine 10. Specifically, to the placingunit 14, a placing-unit-residue detection sensor (or first paper-sheet detection unit) 60 is provided for detecting whether or not there are some paper sheets P remaining on the placingunit 14. Further, to thereject unit 30, a reject-unit paper-sheet detection sensor (or second paper-sheet detection unit) 62 is provided for detecting whether or not there are some reject paper sheets P' remaining in thereject unit 30. Additionally, to thetransport unit 22 located on the upstream side relative to the recognition andcounting unit 24, a paper-sheet tracking detection sensor (or third paper-sheet detection unit) 64 is provided for detecting each paper sheet P when the paper sheet P transported by thetransport unit 22 passes through this paper-sheettracking detection sensor 64. InFigs. 1 and2 , while the paper-sheettracking detection sensor 64 is located on the upstream side relative to the recognition andcounting unit 24 in thetransport unit 22, this paper-sheettracking detection sensor 64 may be located on the downstream side relative to the recognition andcounting unit 24. - Now, the position in which the paper-sheet
tracking detection sensor 64 is located will be described more specifically. Namely, this paper-sheettracking detection sensor 64 is provided to thetransport unit 22, in such a position that interval of time between the time one paper sheet P is detected by the paper-sheettracking detection sensor 64 and the time this paper sheet P is fed to the stackingunit 26, is substantially matched with the time required for theshutter 40 to be moved from the closing position (seeFig. 1 ) in which the opening in the front face of the stackingunit 26 is closed to the opening position (seeFig. 2 ) in which the opening is opened (e.g., 0.5 seconds). With such provision of the paper-sheettracking detection sensor 64 in the position as described above in thetransport unit 22, if theshutter 40 starts to move from its closing position shown inFig. 1 when one paper sheet P is detected by the paper-sheettracking detection sensor 64, this paper sheet P reaches the stackingunit 26 at the same time theshutter 40 reaches the opening position shown inFig. 2 . Thus, the operator can take out each paper sheet P from the stackingunit 26, immediately after the paper sheet P reaches the stackingunit 26. - Additionally, a
diversion timing sensor 66 is provided on the upstream side relative to thediverter 32 in thetransport unit 22. Thediverter 32 is optionally moved to either one of a first position for feeding each paper sheet P to the stackingunit 26 and a second position for feeding the paper sheet P to thereject unit 30, at each timing on which the paper sheet P is detected by the diversion timing sensor 66 (e.g., inFigs. 1 and2 , thediverter 32 is shown to be located in the position for feeding the paper sheet P to the stacking unit 26). With this configuration, each paper sheet P that has been transported by thetransport unit 22 and detected by thediversion timing sensor 66 is selectively fed, by thediverter 32, to either one of the two transport paths. - Further, a stacking-unit paper-
sheet detection sensor 68 is provided on a downstream-side end of thetransport unit 22 extending toward the stackingunit 26. This stacking-unit paper-sheet detection sensor 68 serves to detect each paper sheet P when the paper sheet P is fed to the stackingwheel 28 from thetransport unit 22. With the provision of this stacking-unit paper-sheet detection sensor 68, the number of the paper sheets P respectively fed to the stackingunit 26 can be counted. - As shown in
Fig. 5 and the like, the paper-sheet counting machine 10 includes acontrol unit 70. Thiscontrol unit 70 serves to control each component of the paper-sheet counting machine 10. More specifically, thiscontrol unit 70 is connected with each of thefeeding unit 16,transport unit 22, recognition andcounting unit 24, stacking-wheel drive unit 29 for driving the stackingwheel 28,diverter 32 andshutter drive unit 50 for driving theshutter 40. In this case, the recognition and counting result on each paper sheet P recognized by the recognition andcounting unit 24 is sent to thecontrol unit 70, while thecontrol unit 70 sends a command signal to each of thefeeding unit 16,transport unit 22, stacking-wheel drive unit 29,diverter 32,shutter drive unit 50 and the like, in order to control such components. Further, thecontrol unit 70 is connected with each of the placing-unit-residue detection sensor 60, reject-unit paper-sheet detection sensor 62, paper-sheettracking detection sensor 64,diversion timing sensor 66 and stacking-unit paper-sheet detection sensor 68, in order to receive each detection result from such sensors. - In addition, the
control unit 70 is connected with the shutter-closing detection sensor 54a and shutter-openingdetection sensor 54b. Thus, thecontrol unit 70 receives information that theshutter 40 is located in the closing position shown inFig. 3 or information that theshutter 40 is located in the opening position shown inFig. 4 , from the shutter-closing detection sensor 54a or shutter-openingdetection sensor 54b. Furthermore, thecontrol unit 70 is connected with adisplay unit 72 and anoperation unit 74. Thedisplay unit 72 andoperation unit 74 are respectively provided to a front face of thecasing 12. In this case, the condition under which the paper sheets P are handled by the paper-sheet counting machine 10, more specifically the information on the number or the like of the paper sheets P counted by the recognition andcounting unit 24, is displayed on thedisplay unit 72. Further, the operator can input various commands to thecontrol unit 70 via theoperation unit 74. - Next, referring to the flow charts of
Figs. 6 through 8 , the operation of the paper-sheet counting machine 10 constructed as described above will be discussed. It is noted that the operation of the paper-sheet counting machine 10 is performed by controlling each component of the paper-sheet counting machine 10, under control of thecontrol unit 70. - First of all, the operator places the paper sheets P to be counted, on the placing
unit 14, in the stacked condition. - In this case, two operational modes, i.e., a with-shutter-operation mode and a without-shutter-operation mode, are provided to the
control unit 70. The with-shutter-operation mode means a mode in which thecontrol unit 70 controls theshutter drive unit 50, in order to open and close the opening in the front face of the stackingunit 26 by using theshutter 40. Meanwhile, the without-shutter-operation mode means a mode in which thecontrol unit 70 does not control theshutter drive unit 50 and thus the opening and closing operation for the opening in the front face of the stackingunit 26 is not performed by theshutter 40. When the paper-sheet counting machine 10 is operated, the operator selects either one of the with-shutter-operation mode and without-shutter-operation mode, via theoperation unit 74. - In the case the without-shutter-operation mode is selected by the operator, via the
operation unit 74, the paper sheets P placed on the placingunit 14 are counted and the so-counted paper sheets P are fed to the stackingunit 26, in a state in which theshutter 40 is kept located in the opening position shown inFig. 2 , or in a state in which the opening in the front face of the stackingunit 26 is kept opened. - Meanwhile, in the case the with-shutter-operation mode is selected by the operator, via the
operation unit 74, the operation shown in the flow charts ofFigs. 6 through 8 is performed. Namely, in an initial state of this operation, theshutter 40 is retreated from the opening in the front face of the stacking unit 26 (i.e., theshutter 40 is located in the opening position shown inFig. 2 ), and thus the opening in the front face of the stackingunit 26 is opened (STEP 1 ofFig. 6 ). - In this case, the
control unit 70 serves to selectively perform a batch process mode, in which thecounting unit 24 counts paper sheets P by the batch number, the batch number being instructed to thecontrol unit 70 via theoperation unit 74. Then, as shown in STEP 2 ofFig. 6 , whether or not the batch process mode is performed is selected by the operator via theoperation unit 74. If the batch process mode is selected to be performed by the operator, the operation, as is shown in the flow charts ofFigs. 7 and8 described later, is performed. The operation of the paper-sheet counting machine 10 associated with this batch process mode will be described later. Meanwhile, if the batch process mode is not selected to be performed, the counting process for the paper sheets P, as will be described below, is performed in accordance with the flow chart ofFig. 6 . - Namely, before the counting process for the paper sheets P by the recognition and
counting unit 24 is started, thecontrol unit 70 controls theshutter drive unit 50 to drive theshutter 40 to close the opening in the front face of the stacking unit 26 (STEP 3 ofFig. 6 ). More specifically, theshutter drive unit 50 rotates therotation shaft 51 in the anticlockwise direction inFig. 4 (i.e., in the direction indicated by the arrow), from the state shown inFig. 4 . As a result, thecircular linking member 44b provided to theplate member 44 is no longer pressed upward inFig. 4 by thecam 52. Thus, theplate member 44 is rotated, by the contraction force of thespring 46, in the anticlockwise direction inFig. 4 , about theshaft 44a, from the state shown inFig. 4 . Therefore, theshutter support unit 42 attached to theplate member 44 is also rotated in the anticlockwise direction inFig. 4 , about theshaft 44a, from the state shown inFig. 4 . Eventually, theshutter support unit 42 is moved from the position shown inFig. 4 to the position shown inFig. 3 . In this way, theshutter 40 is moved from the opening position as shown inFig. 2 to the closing position as shown inFig. 1 , thus closing the opening in the front face of the stackingunit 26. - The timing on which the opening in the front face of the stacking
unit 26 is closed by theshutter 40 is set, as the timing before the counting process for the paper sheets P by the recognition andcounting unit 24 is started, i.e., the timing before the counting process for the paper sheets P is started or timing substantially the same as the start of the counting process for the paper sheets P. If the opening in the front face of the stackingunit 26 is closed by theshutter 40 at substantially the same timing as the start of the counting process for the paper sheets P, the time required for the entire process for the paper sheets P in the paper-sheet counting machine 10 can be reduced. - The
control unit 70 may control theshutter drive unit 50 to drive theshutter 40 to start closing the opening in the front face of the stackingunit 26, at the same time as the start of the counting process for the paper sheets P by the recognition andcounting unit 24, thereby to close the opening in the front face of the stackingunit 26, while counting the paper sheets P. In this case, the opening in the front face of the stackingunit 26 is closed, in a period of time during which the paper sheets P are counted. Therefore, the time required for the entire process for the paper sheets P in the paper-sheet counting machine 10 can be reduced, as compared with the case in which the paper sheets P are counted after the opening in the front face of the stackingunit 26 is closed. - Thereafter, the paper sheets P, respectively placed in the stacked condition on the placing
unit 14, are fed to thetransport unit 22 in thecasing 12, one by one, by thefeeding unit 16, successively, from the paper sheet P located at the lowermost layer, and then transported by thetransport unit 22. At this time, the recognition and counting process for the paper sheets P is performed by the recognition andcounting unit 24. In this case, each paper sheet P recognized, as the normal paper sheet, by the recognition andcounting unit 24 is fed to the stackingunit 26 via thediverter 32. More specifically, the paper sheets P are fed, one by one, from thetransport unit 22 to the stackingwheel 28. Then, the stackingwheel 28 receives each paper sheet P fed from thetransport unit 22, between the twovanes 28a thereof. Thereafter, each paper sheet P received between the twovanes 28a is fed into the stackingunit 26. In this way, the paper sheets P can be arranged in the stackingunit 26, by the stackingwheel 28. At this time, since the opening in the front face of the stackingunit 26 is closed by theshutter 40, the operator cannot take out the paper sheets P stacked in the stackingunit 26. - Meanwhile, each paper sheet that is not recognized as the normal paper sheet by the recognition and
counting unit 24 and each paper sheet that cannot be recognized by the recognition andcounting unit 24 are respectively fed, as the reject paper sheets P', to thereject unit 30, by thediverter 32. Since the opening is provided in the front face of thereject unit 30, the operator can take out the reject paper sheets P' stacked in thereject unit 30, via this opening. - When a maximum number of the reject paper sheets P' that can be stored in the
reject unit 30 is set in advance, and when the number of the reject paper sheets P' fed to thereject unit 30 reaches this preset maximum number or when thereject unit 30 is full up with the reject paper sheets P', during the counting process for the paper sheets P in the paper-sheet counting machine 10 (STEP 4 ofFig. 6 ), this condition of thereject unit 30 is displayed on thedisplay unit 72, and the counting process for the paper sheets P in the paper-sheet counting machine 10 is once stopped. Thereafter, the operator takes out the reject paper sheets P' from the reject unit 30 (STEP 5 ofFig. 6 ), sets again such reject paper sheets P' on the placingunit 14, and starts again the counting process for the paper sheet P, via the operation unit 74 (STEP 6 ofFig. 6 ). In this way, the counting process for the paper sheets P is started again in the paper-sheet counting machine 10. In place of the operator starting again the counting process for the paper sheets P, via theoperation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the reject paper sheets P', respectively taken out form thereject unit 30, on the placingunit 14. - Further, when a maximum number of the paper sheets P that can be stored in the stacking
unit 26 is set in advance, and when the number of the paper sheets P fed to the stackingunit 26 reaches this preset maximum number or when the stackingunit 26 is full up with the paper sheets P, during the counting process for the paper sheets P in the paper-sheet counting machine 10 (STEP 7 ofFig. 6 ), this condition of the stackingunit 26 is displayed on thedisplay unit 72, and the counting process for the paper sheets P in the paper-sheet counting machine 10 is once stopped. Then, thecontrol unit 70 controls theshutter drive unit 50 to move theshutter 40 to the opening position shown inFig. 2 from the closing position shown inFig. 1 . As a result, the opening in the front face of the stackingunit 26 is opened (STEP 8 ofFig. 6 ). Thereafter, the operator takes out the paper sheets P stacked in the stackingunit 26 via the opening in the front face of the stacking unit 26 (STEP 9 ofFig. 6 ), and then starts again the counting process for the paper sheet P, via the operation unit 74 (STEP 10 ofFig. 6 ). In this way, the counting process for the paper sheets P in the paper-sheet counting machine 10 is started again. Also in this case, in place of the operator starting again the counting process for the paper sheets P, via theoperation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator takes out the paper sheets P form the stackingunit 26. In this case, before the counting process for the paper sheets P is started again by the recognition andcounting unit 24, thecontrol unit 70 controls theshutter drive unit 50 to drive theshutter 40 to close the opening in the front face of the stacking unit 26 (STEP 3 ofFig. 6 ). - In this manner, the counting process for the paper sheets P in the paper-
sheet counting machine 10 is continued, until no paper sheet P remains on the placingunit 14. During this counting process, the placing-unit-residue detection sensor 60 detects whether or not there are some paper sheets P remaining on the placing unit 14 (STEP 11 ofFig. 6 ). When the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placingunit 14, this detection result is displayed on thedisplay unit 72. Thereafter, the reject-unit paper-sheet detection sensor 62 detects whether or not there are some reject paper sheets P' remaining in the reject unit 30 (STEP 12 ofFig. 6 ). When the reject-unit paper-sheet detection sensor 62 detects that there are some reject paper sheets P' remaining in thereject unit 30, this detection result is displayed on thedisplay unit 72. Thereafter, the operator takes out the reject paper sheets P' from the reject unit 30 (STEP 15 ofFig. 6 ), sets again such paper sheets P' on the placingunit 14, and then starts again the counting process for the paper sheets P, via the operation unit 74 (STEP 16 ofFig. 6 ). In this way, the counting process for the paper sheets P in the paper-sheet counting machine 10 is started again. In place of the operator starting again the counting process for the paper sheets P, via theoperation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the reject paper sheets P', respectively taken out form thereject unit 30, on the placingunit 14. - Meanwhile, when the placing-unit-
residue detection sensor 60 detects that there is no paper sheet P remaining on the placingunit 14, and when the reject-unit paper-sheet detection sensor 62 detects that there is no reject paper sheet P' remaining in thereject unit 30, the counting process for the paper sheets P in the paper-sheet counting machine 10 is ended (STEP 13 ofFig. 6 ). Thereafter, thecontrol unit 70 controls theshutter drive unit 50 to move theshutter 40 to the opening position shown inFig. 2 from the closing position shown inFig. 1 . Thus, the opening in the front face of the stackingunit 26 is opened (STEP 14 ofFig. 6 ). Then, the operator takes out the paper sheets P stacked in the stackingunit 26, via the opening in the front face of the stackingunit 26. In this way, the operation of the paper-sheet counting machine 10, in the case of not performing the batch process mode, is completed. - According to the operation of the paper-
sheet counting machine 10 as shown in the flow chart ofFig. 6 , as shown in the operation in theSTEP 3 ofFig. 6 , thecontrol unit 70 controls theshutter drive unit 50 to drive theshutter 40 to close the opening provided in the front face of the stackingunit 26, before the counting process for the paper sheets P is started by the recognition andcounting unit 24. Therefore, the opening in the front face of the stackingunit 26 is closed by theshutter 40, during the period of time in which the counting process for the paper sheets P is performed by the recognition andcounting unit 24, thereby preventing the dust accumulated in thecasing 12 of the paper-sheet counting machine 10 and/or dust attached to each paper sheet from being blown out toward the operator. - Further, as shown in the STEP 11 and STEP 13 of
Fig. 6 , when the paper sheets P placed on the placingunit 14 are all fed to the recognition andcounting unit 24 and thus the placing-unit-residue detection sensor 60 detects that there is no paper sheet remaining on the placingunit 14, thecontrol unit 70 controls theshutter drive unit 50 to retreat theshutter 40 from the opening provided in the front face of the stackingunit 26 to open the opening. Alternatively, skipping the operation in theSTEP 12 ofFig. 6 , or thecontrol unit 70 may serve to open the opening in the front face of the stackingunit 26, once the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placingunit 14, irrespectively of whether or not there are some reject paper sheets P' remaining in thereject unit 30. In addition, interval of time between the time the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placingunit 14 and the time thecontrol unit 70 controls theshutter drive unit 50 to retreat theshutter 40 from the opening in the front face of the stackingunit 26, may be optionally altered, by the operator, with appropriate settings via theoperation unit 74. In this case, the operator can optionally select the order of priority, between the dustproof and/or soundproofing in the paper-sheet counting machine 10 and the reduction of the time required for handling the paper sheets P. - Further, as shown in the STEP 11 and
STEP 12 ofFig. 6 , when the reject-unit paper-sheet detection sensor 62 detects that there are some reject paper sheets P' remaining in thereject unit 30 even though the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placingunit 14, thecontrol unit 70 serves to drive theshutter 40 to keep closing the opening provided in the front face of the stackingunit 26. This is because, when there are some reject paper sheets P' remaining in thereject unit 30 even though there is no paper sheet P remaining on the placingunit 14, it is necessary for the operator to take out such reject paper sheets P' from thereject unit 30, and set again the reject paper sheets P' on the placingunit 14, and then start again the counting process for the paper sheets P in the paper-sheet counting machine 10. - In the operation of the paper-
sheet counting machine 10 as shown in the flow chart ofFig. 6 , as shown in the operation in the STEP 7 ofFig. 6 , when the paper-sheettracking detection sensor 64 provided to thetransport unit 22 detects a certain paper sheet, with which the stackingunit 26 will be full up upon receiving thereof, thecontrol unit 70 may control theshutter drive unit 50 to retreat theshutter 40 from the opening in the front face of the stackingunit 26 to open the opening. Due to this operation, as compared with the case in which theshutter drive unit 50 starts to move theshutter 40 once the number of the paper sheets P fed to the stackingunit 26 reaches the preset maximum number of the paper sheets P that can be stored in the stackingunit 26 or once the stackingunit 26 is full up with the paper sheets P, the opening in the front face of the stackingunit 26 can be opened more rapidly, thereby to substantially reduce the time required for the entire process for the paper sheets P. It is noted that interval of time between the time the paper-sheettracking detection sensor 64 detects the paper sheet P, with which the stackingunit 26 will be full up upon receiving thereof, and the time thecontrol unit 70 controls theshutter drive unit 50 to retreat theshutter 40 from the opening in the front face of the stackingunit 26, may be optionally altered, by the operator, with proper settings via theoperation unit 74. In this case, the operator can optionally select the order of priority, between the dustproof or soundproofing in the paper-sheet counting machine 10 and the reduction of the time required for handling the paper sheets P. - As described above, the paper-sheet
tracking detection sensor 64 is provided in such a position that interval of time between the time one paper sheet P is detected by the paper-sheettracking detection sensor 64 and the time this paper sheet P is fed to the stackingunit 26, is substantially matched with the time required for theshutter 40 to be moved from the closing position (seeFig. 1 ) in which the opening in the front face of the stackingunit 26 is closed to the opening position (seeFig. 2 ) in which the opening is opened. Therefore, when the paper-sheettracking detection sensor 64 detects a certain paper sheet, with which the stackingunit 26 will be full up upon receiving this paper sheet P fed thereto, and then this paper sheet P actually reaches the stackingunit 26, the opening in the front face of the stackingunit 26 is just opened. Thus, the operator can take out a batch of the paper sheets P stacked in the stackingunit 26, just after the certain paper sheet P reaches the stackingunit 26. - Now, referring to the flow charts of
Figs. 7 and8 , the operation of the paper-sheet counting machine 10, in the case the batch process mode is selected by the operator, will be described. - First, the operator designates the batch number of the paper sheets, via the
operation unit 74. Then, thecontrol unit 70 compares the batch number inputted to thecontrol 70 via theoperation unit 74 with a preset number (e.g., ten) of the paper sheets (STEP 21 ofFig. 7 ). If the batch number inputted to thecontrol unit 70 is equal to or greater than the preset number, the operation, shown in the flow chart ofFig. 8 described later, is performed. The operation of the paper-sheet counting machine 10 in the batch process mode will be described later. Meanwhile, in the case the batch number inputted to thecontrol unit 70 via theoperation unit 74 is smaller than the preset number, thecontrol unit 70 serves to keep theshutter 40 retreated from the opening in the front face of the stackingunit 26, thereby to keep this opening opened. Thereafter, the counting process for the paper sheets P is performed, as will be described below. - Namely, the paper sheets P respectively placed, in the stacked condition, on the placing
unit 14 are fed, one by one, to thetransport unit 22 in thecasing 12, by thefeeding unit 16, successively, from the paper sheet P located at the lowermost layer, and then transported by thetransport unit 22. During this operation, the paper sheets P are recognized and counted by the recognition andcounting unit 24. In this case, each paper sheet P recognized as the normal paper sheet by the recognition andcounting unit 24 is fed to the stackingunit 26 by thediverter 32. At this time, the paper sheets P are arranged in the stackingunit 26 by the stackingwheel 28. - Meanwhile, each paper sheet that is not recognized as the normal paper sheet by the recognition and
counting unit 24 and each paper sheet that cannot be recognized by the recognition andcounting unit 24 are respectively fed, as the reject paper sheets P', to thereject unit 30, by thediverter 32. Since the opening is provided in the front face of thereject unit 30, the operator can take out such reject paper sheets P' stacked in thereject unit 30, via this opening. - As described above, the maximum number of the reject paper sheets P' that can be stored in the
reject unit 30 is set, in advance. In this case, when the number of the reject paper sheets P' fed to thereject unit 30 reaches the preset maximum number of the reject paper sheets P' that can be stored therein, or when thereject unit 30 is full up with the reject paper sheets P', during the counting process for the paper sheets P in the paper-sheet counting machine 10 (STEP 22 ofFig. 7 ), this condition of thereject unit 30 is displayed on thedisplay unit 72, and the counting process for the paper sheets P in the paper-sheet counting machine 10 is once stopped. Thereafter, the operator takes out the reject paper sheets P' from the reject unit 30 (STEP 23 ofFig. 7 ), sets again such reject paper sheets P' on the placingunit 14, and starts again the counting process for the paper sheets P, via the operation unit 74 (STEP 24 ofFig. 7 ). In this way, the counting process for the paper sheets P is started again in the paper-sheet counting machine 10. In place of the operator starting again the counting process for the paper sheets P, via theoperation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the reject paper sheets P', respectively taken out form thereject unit 30, on the placingunit 14. - Further, when the number of the paper sheets P respectively fed to the stacking
unit 26 reaches the batch number inputted to thecontrol unit 70, or when one batch process is completed, during the counting process for the paper sheets P in the paper-sheet counting machine 10 (STEP 25 ofFig. 7 ), this condition or state is displayed on thedisplay unit 72, and the counting process for the paper sheets P in the paper-sheet counting machine 10 is ended (STEP 26 ofFig. 7 ). At this time, since the opening in the front face of the stackingunit 26 is kept opened, the operator can take out the paper sheets P stacked in the stackingunit 26, via the opening in the front face of the stackingunit 26. In this way, the operation of the paper-sheet counting machine 10 for one batch process is completed. Thereafter, when the operator starts again the counting process for the paper sheets P, via theoperation unit 74, the next batch process is performed as shown in the flow chart ofFig. 7 . - Meanwhile, when the number of the paper sheets P fed to the stacking
unit 26 does not reach the batch number inputted to thecontrol unit 70, and when the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placing unit 14 (STEP 27 ofFig. 7 ), this condition is displayed on thedisplay unit 72. Then, the reject-unit paper-sheet detection sensor 62 detects whether or not there are some reject paper sheets P' remaining in the reject unit 30 (STEP 28 ofFig. 7 ). As a result, when the reject-unit paper-sheet detection sensor 62 detects the reject paper sheets P' remaining in thereject unit 30, this condition is further displayed on thedisplay unit 72. Then, the operator takes out the reject paper sheets P' from the reject unit 30 (STEP 29 ofFig. 7 ), sets again such reject paper sheets P' on the placingunit 14, and then starts again the counting process for the paper sheets P, via the operation unit 74 (STEP 30 ofFig. 7 ). In this way, the counting process for the paper sheets P in the paper-sheet counting machine 10 is started again. In place of the operator starting again the counting process for the paper sheets P, via theoperation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the reject paper sheets P', respectively taken out form thereject unit 30, on the placingunit 14. - Meanwhile, when the placing-unit-
residue detection sensor 60 detects that there is no paper sheet P remaining on the placingunit 14, and when the reject-unit paper-sheet detection sensor 62 detects that there is no reject paper sheet P' remaining in thereject unit 30, if the operator inputs a command for terminating the counting process for the paper sheets P, to thecontrol unit 70, via the operation unit 74 (STEP 31 ofFig. 7 ), the counting process for the paper sheets P in the paper-sheet counting machine 10 is ended (STEP 26 ofFig. 7 ). At this time, since the opening in the front face of the stackingunit 26 is kept opened, the operator can take out the paper sheets P stacked in the stackingunit 26, via the opening in the front face of the stackingunit 26. - Further, when the placing-unit-
residue detection sensor 60 detects that there is no paper sheet P remaining on the placingunit 14, and when the reject-unit paper-sheet detection sensor 62 detects that there is no reject paper sheet P' remaining in thereject unit 30, if the operator places additional paper sheets P on the placing unit 14 (STEP 32 ofFig. 7 ), and then starts again the counting process for the paper sheets P, via the operation unit 74 (STEP 33 ofFig. 7 ), the counting process for the paper sheets P in the paper-sheet counting machine 10 is restarted. In place of the operator starting again the counting process for the paper sheets, via theoperation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the additional paper sheets P on the placingunit 14. - In the operation of the paper-
sheet counting machine 10 as shown in the flow chart ofFig. 7 , as shown in the operation in the STEP 21 ofFig. 7 , when thecontrol unit 70 performs the counting process for the paper sheets P in the batch process mode, and when the batch number of the paper sheets P inputted to thecontrol unit 70 is smaller than the preset number, thecontrol unit 70 serves to retreat theshutter 40 from the opening provided in the front face of the stackingunit 26 to open this opening. Namely, in the case the batch number inputted to thecontrol unit 70 is relatively small, if the opening and closing operation of theshutter 40 is performed for each batch process, the time required for the entire process for the paper sheets P becomes considerably long. Therefore, in this case, by keeping the opening opened in the front face of the stackingunit 26, the time required for the entire process for the paper sheets P can be reduced. - Next, referring to the flow chart of
Fig. 8 , the operation of the paper-sheet counting machine 10 will be further described, when the operator selects the batch process mode, and the batch number of the paper sheets inputted to thecontrol unit 70 is equal to or greater than the preset number. - Before starting the counting process for the paper sheets P by the recognition and
counting unit 24, thecontrol unit 70 controls theshutter drive unit 50 to drive theshutter 40 to close the opening in the front face of the stacking unit 26 (STEP 41 ofFig. 8 ). Then, the counting process for the paper sheets P is performed, as will be described below. - Namely, the paper sheets P, respectively placed in the stacked condition on the placing
unit 14, are fed to thetransport unit 22 in thecasing 12, one by one, by thefeeding unit 16, successively, from the paper sheet P located at the lowermost layer, and then transported by thetransport unit 22. At this time, the recognition and counting process for the paper sheets P is performed by the recognition andcounting unit 24. In this case, each paper sheet P recognized, as the normal paper sheet, by the recognition andcounting unit 24 is fed to the stackingunit 26 via thediverter 32. Then, the paper sheets P are arranged in the stackingunit 26, by the stackingwheel 28. At this time, since the opening in the front face of the stackingunit 26 is closed by theshutter 40, the operator cannot take out the paper sheets P stacked in the stackingunit 26. - Meanwhile, each paper sheet that is not recognized as the normal paper sheet by the recognition and
counting unit 24, and each paper sheet that cannot be recognized by the recognition andcounting unit 24 are respectively fed, as the reject paper sheets P' , to thereject unit 30, via thediverter 32. In this case, since the opening is provided in the front face of thereject unit 30, the operator can take out the reject paper sheets P' stacked in thereject unit 30, via the opening. - As described above, when the preset maximum number of the reject paper sheets P' that can be stored in the
reject unit 30 is set, and when the number of the reject paper sheets P' fed to thereject unit 30 reaches the preset maximum number of the reject paper sheets P' that can be stored therein or when thereject unit 30 is full up with such reject paper sheets P', during the counting process for the paper sheets P in the paper-sheet counting machine 10 (STEP 42 ofFig. 8 ), this condition of thereject unit 30 is displayed on thedisplay unit 72, and the counting process for the paper sheets P in the paper-sheet counting machine 10 is once stopped. Thereafter, the operator takes out the reject paper sheets P' from the reject unit 30 (STEP 43 ofFig. 8 ), sets again such reject paper sheets P' on the placingunit 14, and starts again the counting process for the paper sheet P, via the operation unit 74 (STEP 44 ofFig. 8 ). In this way, the counting process for the paper sheets P is started again in the paper-sheet counting machine 10. In place of the operator starting again the counting process for the paper sheets P, via theoperation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the reject paper sheets P', respectively taken out form thereject unit 30, on the placingunit 14. - Further, when the number of the paper sheets P respectively fed to the stacking
unit 26 reaches the batch number inputted to thecontrol unit 70, or when one batch process is completed, during the counting process for the paper sheets P in the paper-sheet counting machine 10 (STEP 45 ofFig. 8 ), this condition is displayed on thedisplay unit 72, and the counting process for the paper sheets P in the paper-sheet counting machine 10 is ended (STEP 46 ofFig. 8 ). Thereafter, thecontrol unit 70 controls theshutter drive unit 50 to move theshutter 40 to the opening position shown inFig. 2 form the closing position shown inFig. 1 . Thus, the opening in the front face of the stackingunit 26 is opened (STEP 47 ofFig. 8 ), and then the operator takes out the paper sheets P stacked in the stackingunit 26, via the opening in the front face of the stackingunit 26. In this way, the operation of the paper-sheet counting machine 10 for one batch process is completed. Thereafter, when the operator starts again the counting process for the paper sheets P, via theoperation unit 74, the next batch process is performed as shown in the flow chart ofFig. 8 . - Meanwhile, when the number of the paper sheets P fed to the stacking
unit 26 does not reach the batch number inputted to thecontrol unit 70, and when the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placing unit 14 (STEP 48 ofFig. 8 ), this condition is displayed on thedisplay unit 72. Thereafter, the reject-unit paper-sheet detection sensor 62 detects whether or not there are some reject paper sheets P' remaining in the reject unit 30 (STEP 49 ofFig. 8 ). When the reject-unit paper-sheet detection sensor 62 detects that there are some reject paper sheets P' remaining in thereject unit 30, this condition is displayed on thedisplay unit 72. Thereafter, the operator takes out the reject paper sheets P' from the reject unit 30 (STEP 50 ofFig. 8 ), sets again such taken-out reject paper sheets P' on the placingunit 14, and then starts again the counting process for the paper sheets P, via the operation unit 74 (STEP 51 ofFig. 8 ). In this way, the counting process for the paper sheets P in the paper-sheet counting machine 10 is started again. In place of the operator starting again the counting process for the paper sheets P, via theoperation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the reject paper sheets P', respectively taken out form thereject unit 30, on the placingunit 14. - Meanwhile, when the placing-unit-
residue detection sensor 60 detects that there is no paper sheet P remaining on the placingunit 14, and when the reject-unit paper-sheet detection sensor 62 detects that there is no reject paper sheet P' remaining in thereject unit 30, if the operator inputs a command for ending the counting process for the paper sheets P, to thecontrol unit 70, via the operation unit 74 (STEP 52 ofFig. 8 ), the counting process for the paper sheets P in the paper-sheet counting machine 10 is ended (STEP 46 ofFig. 8 ). Thereafter, thecontrol unit 70 controls theshutter drive unit 50 to move theshutter 40 to the opening position shown inFig. 2 from the closing position shown inFig. 1 . Thus, the opening in the front face of the stackingunit 26 is opened (STEP 47 ofFig. 8 ). Then, the operator takes out the paper sheets P stacked in the stackingunit 26, via the opening in the front face of the stackingunit 26. - Meanwhile, when the placing-unit-
residue detection sensor 60 detects that there is no paper sheet P remaining on the placingunit 14, and when the reject-unit paper-sheet detection sensor 62 detects that there is no reject paper sheet P' remaining in thereject unit 30, if the operator places the additional paper sheets P on the placing unit 14 (STEP 53 ofFig. 8 ), and starts again the counting process for the paper sheets P, via the operation unit 74 (STEP 54 ofFig. 8 ), the counting process for the paper sheets P in the paper-sheet counting machine 10 is restarted. In place of the operator starting again the counting process for the paper sheets, via theoperation unit 74, the paper-sheet counting machine 10 may be configured to restart the counting process for the paper sheets P, automatically, therein, once the operator places the additional paper sheets P on the placingunit 14. - According to the operation of the paper-
sheet counting machine 10 as shown in the flow chart ofFig. 8 , as shown in the operation in the STEP 45 and STEP 48 ofFig. 8 , when thecontrol unit 70 performs the counting process for the paper sheets P in the batch process mode, and when the placing-unit-residue detection sensor 60 detects that there is no paper sheet P remaining on the placingunit 14, if the number of the paper sheets P counted by the recognition andcounting unit 24 does not reach the batch number, thecontrol unit 70 controls theshutter drive unit 50 to drive theshutter 40 to keep closing the opening provided in the front face of the stackingunit 26. Namely, in this case, as shown in theSTEP 53 and STEP 54 ofFig. 8 , it is necessary for the operator to place the additional paper sheets P on the placingunit 14 and start again the counting process for the paper sheets P, via theoperation unit 74. Therefore, even in the case the operation of the paper-sheet counting machine 10 is stopped, while the actual number of the paper sheets P fed to the stackingunit 26 is slightly short of the batch number inputted to thecontrol unit 70, this paper-sheet counting machine 10 can prevent the operator from misunderstanding that the batch process has been properly performed and thus the number of the paper sheets P stacked in the stackingunit 26, at this point of time, is correctly corresponding to the batch number. Accordingly, this paper-sheet counting machine 10 can securely prevent the operator from mistakenly taking out the paper sheets P from the stackingunit 26. - Alternatively, in the operation of the paper-
sheet counting machine 10 as shown in the flow chart ofFig. 8 , thecontrol unit 70 may control theshutter drive unit 50 to retreat theshutter 40 from the opening in the front face of the stackingunit 26 to open this opening, at a point of time that the paper-sheettracking detection sensor 64 provided to thetransport unit 22 detects the last paper sheet P of the batch number. With this operation, as compared with the case of starting to move theshutter 40 once the counting process for one batch process is completely finished or once the stacking-unit paper-sheet detection sensor 68 detects that the number of paper sheets P respectively fed to the stackingunit 26 reaches the batch number, the opening in the front face of the stackingunit 26 can be opened more rapidly, thereby to reduce the time required for the entire process for the paper sheets P. It is noted that interval of time between the time the paper-sheettracking detection sensor 64 detects the last paper sheet P of the batch number and the time thecontrol unit 70 controls theshutter drive unit 50 to retreat theshutter 40 from the opening in the front face of the stackingunit 26, may be optionally altered, by the operator, with appropriate settings, via theoperation unit 74. In this case, the operator can optionally select the order of priority, between the dustproof or soundproofing in the paper-sheet counting machine 10 and the reduction of the time required for handling the paper sheets P. - Further, as described above, the paper-sheet
tracking detection sensor 64 is provided to thetransport unit 22, in such a position that interval of time between the time one paper sheet P is detected by the paper-sheettracking detection sensor 64 and the time this paper sheet P is fed to the stackingunit 26, is substantially matched with the time required for theshutter 40 to be moved from the closing position (seeFig. 1 ) in which the opening in the front face of the stackingunit 26 is closed to the opening position (see -
Fig. 2 ) in which the opening is opened. With this configuration, the opening in the front face of the stackingunit 26 can be just opened at the time the last paper sheet P of the batch number actually reaches the stackingunit 26 after this paper sheet P is detected by the paper-sheettracking detection sensor 64. As such, the operator can take out one batch of the paper sheets P stacked in the stackingunit 26, just after the last paper sheet P of the batch number reaches the stackingunit 26. - As stated above, according to the paper-
sheet counting machine 10 of this embodiment, the opening and closing operation for the opening provided in the front face of the stackingunit 26 can be optionally performed by theshutter 40 driven by theshutter drive unit 50 controlled by thecontrol unit 70. Therefore, the opening provided in the front face of the stackingunit 26 can be selectively closed by theshutter 40. Thus, when thisshutter 40 closes the opening, the blowing out of the dust accumulated in thecasing 12 of the paper-sheet counting machine 10 and/or dust attached to each paper sheet, toward the operator, can be successfully prevented. Further, when theshutter 40 closes the opening in the front face of the stackingunit 26, the unwanted leakage of the sound generated in the interior of the paper-sheet counting machine 10 to the outside can be effectively prevented during the operation of themachine 10. - It is noted that the paper-sheet counting machine according to the present invention is not limited to such an aspect as described above. For instance, any suitable variations or modifications can be made to the mechanism for driving the aforementioned shutter of the paper-sheet counting machine shown in
Figs. 3 and 4 . -
Figs. 9 and 10 respectively show one variation of the driving mechanism for driving the shutter in the paper-sheet counting machine of the present invention. Of these drawings,Fig. 9 shows one side view for illustrating the construction of the shutter, shutter support unit for supporting the shutter, shutter drive unit, a plurality of gears, torque limiter and the like, respectively provided in the paper-sheet counting machine related to one variation of the present invention.Fig. 10 shows one top view for illustrating the shutter, shutter support unit for supporting the shutter, shutter drive unit, a plurality of gears, torque limiter and the like, respectively shown inFig. 9 , when such units or parts are respectively seen from above. It is noted thatFig. 9 is provided for illustrating the construction of the shutter and the like when the shutter closes the opening provided in the front face of the stacking unit. - In the shutter drive mechanism of the paper-sheet counting machine in the variation of the present invention as shown in
Figs. 9 and 10 , like parts or units are respectively designated by like reference numerals respectively shown inFigs. 1 through 5 . - As shown in
Figs. 9 and 10 , afirst gear 80 is attached to theshutter drive unit 50 composed of the motor, such that thisfirst gear 80 is rotated by theshutter drive unit 50 in both of the clockwise and anticlockwise directions inFig. 9 . Further, asecond gear 81 substantially larger, in size, than thefirst gear 80 is provided in the vicinity of thefirst gear 80. The first andsecond gears first gear 80 to thesecond gear 81. - On one side face of the second gear 81 (more specifically, on an upper side face of the
second gear 81 inFig. 10 ), athird gear 82 substantially smaller, in size, than thesecond gear 81 is attached. The second andthird gears second gear 81 is rotated, thethird gear 82 is rotated in synchronism with thesecond gear 81. Further, afourth gear 83 substantially larger, in size, than thethird gear 82 is provided in the vicinity of thethird gear 82. Such third andfourth gears third gear 82 to thefourth gear 83. - On one side face of the
fourth gear 83, afifth gear 85 substantially smaller, in size, than thefourth gear 83 is attached, via atorque limiter 84. Such fourth andfifth gears fourth gear 83 is rotated, thefifth gear 85 is rotated in synchronism with theforth gear 83. In this case, if the rotation force greater than a preset torque is applied to thetorque limiter 84 provided between thefourth gear 83 and thefifth gear 85, the connection between thefourth gear 83 and thefifth gear 85 is released, and then thefifth gear 85 will be rotated freely relative to thefourth gear 83. - In addition, a
sixth gear 86 substantially larger, in size, than thefifth gear 85 is provided in the vicinity of thefifth gear 85. Such fifth andsixth gears fifth gear 85 to thesixth gear 86. Further, thesixth gear 86 is attached to theshutter support unit 42 for supporting theshutter 40. Therefore, thesixth gear 86 is rotated integrally with theshutter support unit 42 about ashaft 86a. - A first notched
portion 86b and a second notchedportion 86c are respectively provided to thesixth gear 86. Additionally, the shutter-closing detection sensor 54a and shutter-openingdetection sensor 54b are respectively fixed in position, in the vicinity of thesixth gear 86. Each of such shutter-closing detection sensor 54a and shutter-openingdetection sensor 54b is composed of the optical sensor. In this case, when theshutter 40 is located in the closing position, the position of the first notchedportion 86b of thesixth gear 86 is substantially matched with the position of the shutter-closing detection sensor 54a. Therefore, the detection of the first notchedportion 86b of thesixth gear 86 by the shutter-closing detection sensor 54a indicates the detection of theshutter 40 located in the closing position. Meanwhile, when theshutter 40 is located in the opening position, the position of the second notchedportion 86c of thesixth gear 86 is substantially matched with the position of the shutter-openingdetection sensor 54b. Therefore, the detection of the second notchedportion 86c of thesixth gear 86 by the shutter-openingdetection sensor 54b indicates the detection of theshutter 40 located in the opening position. - Now, the operation of the shutter drive mechanism of the paper-sheet counting machine related to the variation of the present invention, as shown in
Figs. 9 and 10 , will be described. - In the case of driving the
shutter 40 to move to the opening position from the closing position shown inFig. 9 , theshutter drive unit 50 composed of the motor serves to rotate thefirst gear 80 in the clockwise direction inFig. 9 . Thus, the driving force exerted from theshutter drive unit 50 is transmitted, from thefirst gear 80, through thesecond gear 81,third gear 82,fourth gear 83,torque limiter 84 andfifth gear 85, up to thesixth gear 86, as such thesixth gear 86 is rotated in the clockwise direction inFig. 9 about theshaft 86a. Therefore, theshutter support unit 42 attached to thesixth gear 86 is also rotated in the clockwise direction inFig. 9 about theshaft 86a. As a result, theshutter 40 is moved from the closing position as shown inFig. 1 to the opening position as shown inFig. 2 . - Meanwhile, in the case of driving the
shutter 40 to move to the closing position from the opening position, theshutter drive unit 50 composed of the motor serves to rotate thefirst gear 80 in the anticlockwise direction inFig. 9 . In this way, the driving force exerted from theshutter drive unit 50 is transmitted, from thefirst gear 80, through thesecond gear 81,third gear 82,fourth gear 83,torque limiter 84 andfifth gear 85, up to thesixth gear 86, as such thesixth gear 86 is rotated in the anticlockwise direction inFig. 9 about theshaft 86a. Thus, theshutter support unit 42 attached to thesixth gear 86 is also rotated in the anticlockwise direction inFig. 9 about theshaft 86a. As a result, theshutter 40 is moved from the opening position as shown inFig. 2 to the closing position as shown inFig. 1 . - As described above, the
torque limiter 84 is provide between theshutter support unit 42 for supporting theshutter 40 and theshutter drive unit 50. Therefore, in the case the operator moves theshutter 40 downward, by hand, from the closing position shown inFig. 1 , when the force applied from the operator to thetorque limiter 84 is greater than the preset torque, thetorque limiter 84 releases the connection between thefourth gear 83 and thefifth gear 85. As such, thefifth gear 85 can be rotated freely relative to thefourth gear 83. Namely, in this case, thetorque limiter 84 serves to block the driving force of theshutter drive unit 50 to be transmitted to theshutter 40. Therefore, even in the period during which the counting process for the paper sheets P is performed by the recognition andcounting unit 24, the operator can move theshutter 40 downward, by hand, from the closing position shown inFig. 1 , thereby to take out the paper sheets P from the stackingunit 26. - Further, even in the case the hand or the like of the operator is placed in the stacking
unit 26 in a period during which theshutter 40 is moved from the opening position shown inFig. 2 to the closing position shown inFig. 1 , if the force applied to thetorque limiter 84 becomes greater than the preset torque once the shutter is in contact with such a hand or the like of the operator, thetorque limiter 84 releases the connection between thefourth gear 83 and thefifth gear 85, thus allowing thefifth gear 85 to be rotated freely relative to thefourth gear 83. In this way, thetorque limiter 84 serves to block the driving force of theshutter drive unit 50 to be transmitted to theshutter 40. Thus, theshutter 40 is stopped when thisshutter 40 is in contact with the hand or the like of the operator, thereby successfully preventing such trouble that the finger or the like of the operator is seriously nipped and injured by theshutter 40.
