DETAILED DESCRIPTION OF THE INVENTION
First Embodiment
<<Configuration>>
Hereinafter, a first embodiment of a paper sheet processing apparatus according to the invention will be described by referring to the drawings. Here, FIGS. 1 to 5 are diagrams for illustrating the first embodiment of the invention. Incidentally, the “paper sheet” in the present application indicates a banknote, a check, a coupon, and the like, but typically indicates the banknote.
As illustrated in FIG. 1, a paper sheet processing apparatus 100 of the embodiment includes a casing 1, a placing unit 11 which is provided in the casing 1 so as to place a plurality of paper sheets thereon, a taking-in unit 10 which takes therein the paper sheets placed on the placing unit 11 one by one, a transport unit 70 (see FIG. 2) which transports the respective paper sheets taken in by the taking-in unit 10 into the casing 1, a recognition unit 20 (see FIG. 2) which recognizes the paper sheets transported by the transport unit 70, a plurality of stacking units 60a to 60d which stack the paper sheets transported by the transport unit 70 and the paper sheets stacked in the stacking units 60a to 60d being able to be removed from the stacking units 60a to 60d via openings thereof to outside, and rejecting units 61a and 61b which reject the paper sheets that are not stacked in the stacking units 60a to 60d. 
Furthermore, in the embodiment, a configuration is described in which the stacking units 60a to 60d include the first stacking unit 60a, the second stacking unit 60b provided adjacent to the first stacking unit 60a, the third stacking unit 60c provided adjacent to the second stacking unit 60b, and the fourth stacking unit 60d provided adjacent to the third stacking unit 60c. However, the invention is not limited thereto as long as a configuration is employed which includes the plurality of stacking units 60a to 60d. Further, in FIG. 1, a configuration is illustrated in which the front surface sides of the stacking units 60a to 60d are opened, but a configuration may be employed in which the paper sheets may be removed from the stacking units 60a to 60d. For example, the front surfaces of the stacking units 60a to 60d may be provided with doors or covers that may be opened or closed so as to cover the openings thereof. Incidentally, the respective stacking units 60a to 60d may stack, for example, five hundred paper sheets.
As illustrated in FIG. 2, the paper sheet processing apparatus also includes a control unit 50 which causes the stacking units 60a to 60d to stack the paper sheets thereon based on the recognition result of the recognition unit 20 and detection sensors 25a to 25d which detect the paper sheets removed from the stacking units 60a to 60d. Furthermore, the detection sensors 25a to 25d are provided so as to respectively correspond to the stacking units 60a to 60d. 
As illustrated in FIG. 2, the taking-in unit 10 includes kicker rollers 16 and 18 which are provided in the placing unit 11 so as to apply a driving force to the paper sheet positioned at the lowermost side and gate mechanisms 12 and 14 which nip the paper sheet applied with the driving force by the kicker rollers 16 and 18 so as to feed the paper sheet into the casing 1. The gate mechanisms 12 and 14 include a feed roller 12 and a gate roller 14 which is provided so as to face the feed roller 12.
Further, the placing unit 11 is provided with a presence/absence sensor 85 which detects the placement of the paper sheet. The transport unit 70 is provided with a plurality of tracking sensors 80a to 801 which detect the track of the paper sheet.
Further, the transport unit 70 is provided with a plurality of dividing members 71a to 71e which appropriately divide the paper sheets transported by the transport unit 70.
Further, as illustrated in FIG. 1, the casing 1 is provided with an operation unit 40 to which an operator may input predetermined information.
When the control unit 50 of the embodiment judges that the paper sheets have been removed from the stacking units 60a to 60d based on information from the detection sensor 25a to 25d, removal information on the removed paper sheets or the stacking units 60a to 60d in which the removed paper sheets were stacked is output to an output unit. The removal information on the removed paper sheets indicates, for example, information on the sorts of the paper sheets such as fitness and version of the paper sheets, information on the number of the paper sheets removed from the stacking units 60a to 60d, or the like. The removal information on the stacking units 60a to 60d in which the removed paper sheets were stacked indicates, for example, information representing the stacking unit from which the paper sheets have been removed among the stacking units 60a to 60d, information on the time at which the paper sheets were removed from the stacking units 60a to 60d, or the like. In a case where the removal information is output as an image display, the output unit may be configured as a main display unit 30 or individual display units 31a to 31d to be described later.
Furthermore, the above-described removal information is stored in a storage unit 55 (see FIG. 3) which is connected to the control unit 50.
As illustrated in FIG. 1, the casing 1 is provided with the main display unit 30 which is configured by, for example, an LCD (Liquid Crystal Display) as the output unit that displays the removal information thereon. The main display unit 30 of the embodiment includes a first main display unit 30a and a second main display unit 30b which is provided adjacent to the first main display unit 30a. Both the first main display unit 30a and the second main display unit 30b are configured by LCDs.
The main display unit 30 of the embodiment displays both the removal information on the removed paper sheets and the removal information on the stacking units 60a to 60d in which the paper sheets were stacked. As an example, the main display unit 30 displays a removal time, a removal place, fitness information, the number of sheets, and the like in time series (see FIG. 4). Furthermore, the information may be displayed only on the first main display unit 30a, may be displayed only on the second main display unit 30b, or may be displayed on both the first main display unit 30a and the second main display unit 30b. 
FIG. 4 illustrates a configuration in which the removal time, the removal place, the fitness information, and the number of sheets are sequentially displayed on the first main display unit 30a or the second main display unit 30b in time series from the left side.
Incidentally, in FIG. 4, “STK” indicates the stacking units (stackers) 60a to 60d, “STK1” indicates the first stacking unit 60a, “STK2” indicates the second stacking unit 60b, “STK3” indicates the third stacking unit 60c, and “STK4” indicates the fourth stacking unit 60d. Furthermore, in a configuration illustrated in FIG. 4, it is assumed that the paper sheet is a banknote. In FIG. 4, “ATM” indicates a banknote which may be used as a banknote to be dispensed by an ATM provided in a financial organization such as a bank, “TLR” indicates a banknote which may not be used in the ATM, but may be used as a banknote to be dispensed by a clerk of the financial organization such as a bank, and “UNFIT” indicates a banknote which may not be used as a banknote to be dispensed by not only the ATM but also the clerk of the financial organization such as a bank.
Furthermore, the banknote which may be used as a banknote to be dispensed by the ATM and the banknote which may not be used in the ATM, but may be used as a banknote to be dispensed by the clerk of the financial organization such as a bank are so-called “fit notes”, and the banknote which may not be used a banknote to be dispensed by not only the ATM but also the clerk of the financial organization such as a bank is a so-called “unfit note”. That is, in the embodiment, the fitness information is judged and displayed as three levels.
Further, as illustrated in FIG. 1, the casing 1 is provided with the individual display units 31a to 31d, which are configured by, for example, LEDs (Light Emitting Diodes), at the positions respectively corresponding to the stacking units 60a to 60d. Then, the individual display units 31a to 31d display the removal information corresponding to the stacking units 60a to 60d. That is, the first individual display unit 31a corresponds to the first stacking unit 60a, and the first individual display unit 31a displays the removal information on the first stacking unit 60a. Similarly, the second individual display unit 31b corresponds to the second stacking unit 60b, the second individual display unit 31b displays the removal information on the second stacking unit 60b, the third individual display unit 31c corresponds to the third stacking unit 60c, the third individual display unit 31c displays the removal information on the third stacking unit 60c, the fourth individual display unit 31d corresponds to the fourth stacking unit 60d, and the fourth individual display unit 31d displays the removal information on the fourth stacking unit 60d. 
When the paper sheets have been removed from the corresponding stacking units 60a to 60d, the individual display units 31a to 31d notify the stacking units 60a to 60d from which the paper sheets have been removed to an operator in a manner such that the display units display “ . . . ” (dot) for a predetermined time or the display units are turned on with a color different from the color in a normal state. Furthermore, when the paper sheets are counted, the individual display units 31a to 31d display the counted number of the paper sheets. Then, during the period in which the counting of the paper sheets ends and the removal of the paper sheets is awaited, the individual display units may display the counted number of sheets in a flickering state.
Incidentally, in the embodiment, a configuration is described in which the removal information is displayed on both the main display unit 30 and the individual display units 31a to 31d, but the invention is not limited thereto. For example, the removal information may be displayed only on the main display unit 30 or the removal information may be displayed only on the individual display units 31a to 31d. Further, the removal information may be displayed on an external device such as a PC connected to the paper sheet processing apparatus 100, and the removal information may not be displayed in the paper sheet processing apparatus 100.
Incidentally, the control unit 50 of the embodiment appropriately changes the sorts of the paper sheets to be stacked in the stacking units 60a to 60d, and causes the respective stacking units 60a to 60d to stack the paper sheets thereon. Further, the control unit 50 changes the sorts of the paper sheets to be stacked in the stacking units 60a to 60d based on the information from the detection sensors 25a to 25d. For example, when the control unit 50 judges that the paper sheets have been removed from the stacking units 60a to 60d based on the information from the detection sensor 25a to 25d, the sorts of the paper sheets to be stacked in the stacking units 60a to 60d are changed to the sorts of the paper sheets which are read first at the next time (Furthermore, when the sorts of the paper sheets to be stacked in the stacking units 60a to 60d are the same as the sorts of the paper sheets read first at the next time, the sorts of the paper sheets to be stacked in the stacking units 60a to 60d are not changed).
<<Operation and Effect>>
Next, an operation and an effect according to the embodiment with the above-described configuration will be described.
According to the embodiment, when the control unit 50 judges that the paper sheets have been removed from the stacking units 60a to 60d based on the information from the detection sensor 25a to 25d, the control unit 50 outputs the removal information on the removed paper sheets or the stacking units 60a to 60d in which the paper sheets were stacked. Then, the removal information is displayed on the main display unit 30 and the individual display units 31a to 31d. For this reason, the operator may reliably recognize the sorts of the paper sheets removed from the stacking units 60a to 60d. 
That is, in a case where a large number of paper sheets are continuously processed in the paper sheet processing apparatus of the related art, the stacking process is stopped once at a time point when the respective stacking units 60a to 60d are fully filled with the paper sheets or a predetermined number of sheets are stacked in the stacking units. Then, the paper sheets are removed from the stacking units 60a to 60d, and the process on the paper sheets is resumed (Furthermore, the removed paper sheets are wound by a rubber band or the like so as to be stored according to the sorts of the paper sheets). In a case where the operation of removing the paper sheets is frequently performed, the operator may forget the sorts of the paper sheets removed from the stacking units 60a to 60d. For example, the operator may forget whether the removed paper sheets are fit notes or unfit notes, or new notes or old notes. As a result, the paper sheets may be stored at wrong places.
On the contrary, according to the embodiment, the removal information is output and the operator may check the removal information. Accordingly, even when an operation of removing the paper sheets is frequently performed, the operator may recognize the sorts of the paper sheets removed from the stacking units 60a to 60d. For this reason, the paper sheets may be accurately stored according to each sort.
Furthermore, in a configuration in which the fitness of the paper sheet is output as the removal information, the operator may sort the paper sheets according to the fitness based on the output information. Furthermore, in a case where the paper sheet is a banknote, the “fitness sorting” indicates the sorting of the banknote which may be used in the ATM, the banknote which may not be used in the ATM, but may be used in the clerk of the financial organization such as a bank, and the banknote which may not be used in not only in the ATM but also the clerk of the financial organization such as a bank.
Further, in a configuration in which the version of the paper sheet is output as the removal information, the operator may sort the paper sheets according to the version based on the output information. Furthermore, in a case where the paper sheet is a banknote, the “version sorting” indicates the sorting of the banknote as a new note and the banknote as an old note.
Incidentally, in a configuration in which the removal information includes information on the sorts of the removed paper sheets, the operator may check the sorts of the removed paper sheets through, for example, the main display unit 30, and hence the operator may reliably recognize the sorts of the paper sheets in his or her hand. For this reason, the operator may reliably and accurately store the paper sheets according to each sort.
Further, in a configuration in which the removal information includes information on the stacking units 60a to 60d from which the paper sheets have been removed, the operator may check the stacking unit from which the paper sheets have been removed among the stacking units 60a to 60d by, for example, the main display unit 30 or the individual display units 31a to 31d. For this reason, the operator may reliably recognize the stacking unit from which the paper sheets in his or her hand have been removed among the stacking units 60a to 60d. Even when the operator forgets the sorts of the paper sheets, the operator may easily remember the sorts of the paper sheets. Incidentally, according to a configuration in which the stacking units 60a to 60d and the sorts of the paper sheets are correlated with one another and the sorts of the paper sheets stacked in the stacking units 60a to 60d are displayed, the operator may reliably recognize the sorts of the paper sheets in his or her hand. For this reason, it is preferable in that the operator may reliably and accurately store the paper sheets according to each sort.
Further, in a configuration in which the removal information includes information on the time at which the paper sheets were removed from the stacking units 60a to 60d, the operator may check the time at which the paper sheets were removed from the stacking units 60a to 60d by, for example, the main display unit 30. For this reason, the operator may reliably recognize the time at which the paper sheets in his or her hand were removed from the stacking units 60a to 60d. Even when the operator forgets the sorts of the paper sheets, the operator may easily remember the sorts of the paper sheets. Incidentally, according to a configuration in which the time at which the paper sheets were removed from the stacking units 60a to 60d and the sorts of the paper sheets are correlated with one another and the sorts of the paper sheets are displayed in addition to the time at which the paper sheets were removed from the stacking units 60a to 60d, the operator may reliably recognize the sorts of the paper sheets in his or her hand. For this reason, it is preferable in that the operator may further reliably and accurately store the paper sheets according to each sort.
Further, in a configuration in which the removal information includes information on the number of the paper sheets removed from the stacking units 60a to 60d, the operator may check the number of the paper sheets removed from the stacking units 60a to 60d by, for example, the main display unit 30.
Incidentally, according to a configuration illustrated in FIG. 4, the removal time (the first row from the left side), the removal place (the second row from the left side), the fitness information (the third row from the left side), and the number of sheets (the fourth row from the left side) are respectively displayed on the first main display unit 30a or the second main display unit 30b. 
For this reason, the operator may check the removal time and how many paper sheets have been removed from which unit among the stacking units 60a to 60d and further may check the result of the fitness sorting of the paper sheets by the first main display unit 30a or the second main display unit 30b. For this reason, the operator may reliably and accurately store the paper sheets in his or her hand according to each sort.
Furthermore, as illustrated in FIG. 5, the first main display unit 30a or the second main display unit 30b may display the version information of the paper sheets (at the fourth row from the left side) in addition to the removal time, the removal place, the fitness information, and the number of sheets. In such a case, the operator may also reliably sort the paper sheets according to the version information. Further, in a case where the paper sheets are sorted according to only the version information, a configuration may be employed in which the version information of the paper sheets is displayed instead of the fitness information of FIG. 4.
Further, in the embodiment, in addition to the display on the main display unit 30, the individual display units 31a to 31d notify the stacking units 60a to 60d from which the paper sheets have been removed to the operator in a manner such that the display units display “ . . . ” for a predetermined time or the display units are turned on with a color different from the color in a normal state in a case where the paper sheets have been removed from the corresponding stacking units 60a to 60d. For this reason, the operator may check the stacking unit from which the paper sheets have been removed among the stacking units 60a to 60d in one glance, and hence the working efficiency may be improved. Incidentally, according to a configuration in which the stacking units 60a to 60d and the sorts of the paper sheets are correlated with one another and the sorts of the paper sheets stacked in the stacking units 60a to 60d are displayed on the main display unit 30, it is preferable in that the operator may reliably recognize the sorts of the paper sheets in his or her hand.
Further, in the embodiment, the sorts of the paper sheets to be stacked in the stacking units 60a to 60d may be appropriately changed and the paper sheets may be stacked in the respective stacking units 60a to 60d. For this reason, the sorts of the paper sheets to be stacked in the stacking units 60a to 60d may be flexibly changed in accordance with the situation.
Further, in the embodiment, information is received from the detection sensors 25a to 25d for detecting the removal of the paper sheets from the stacking units 60a to 60d, and the sorts of the paper sheets to be stacked in the stacking units 60a to 60d are changed. For this reason, when the paper sheets have been removed from the stacking units 60a to 60d, the sorts of the paper sheets may be automatically and appropriately changed, and hence the usage efficiency of the stacking units 60a to 60d may be improved.
Second Embodiment
Next, a second embodiment of the invention will be described.
In the first embodiment, a configuration is described in which the control unit 50 appropriately changes the sorts of the paper sheets to be stacked in the stacking units 60a to 60d and causes the respective stacking units 60a to 60d to stack the paper sheets thereon. However, in the second embodiment, the control unit 50 fixes the sorts of the paper sheets to be stacked in the stacking units 60a to 60d, and causes the respective stacking units 60a to 60d to stack the paper sheets thereon.
In the second embodiment, the other configurations are substantially the same as those of the first embodiment. In the second embodiment, the same reference numerals are given to the same components as those of the first embodiment, and the detailed description thereof will not be repeated here.
In the embodiment, the same effect as that of the first embodiment may also be obtained. Since the effect is specifically described in the first embodiment, particularly important points will be described in the description of the effect of the embodiment.
In the embodiment, when the control unit 50 judges that the paper sheets have been removed from the stacking units 60a to 60d based on the information from the detection sensor 25a to 25d, the control unit 50 outputs the removal information on the removed paper sheets or the stacking units 60a to 60d in which the paper sheets were stacked, and the removal information is displayed on the main display unit 30 and the individual display units 31a to 31d. For this reason, the operator may reliably recognize the sorts (for example, the fitness sorts or the version) of the paper sheets removed from the stacking units 60a to 60d. 
Particularly, in a configuration in which the removal information includes information on the sorts of the removed paper sheets, the operator may check the sorts of the removed paper sheets by, for example, the main display unit 30, and hence the operator may reliably recognize the sorts of the paper sheets in his or her hand. For this reason, the paper sheets may be accurately and reliably stored according to each sort.
Further, in a configuration in which the removal information includes information on the stacking units 60a to 60d from which the paper sheets have been removed, the operator may check the stacking unit from which the paper sheets have been removed among the stacking units 60a to 60d by, for example, the main display unit 30 or the individual display units 31a to 31d. In the embodiment, since the sorts of the paper sheets to be stacked in the stacking units 60a to 60d are fixed, if the operator may recognize the stacking unit from which the paper sheets have been removed among the stacking units 60a to 60d, the operator may reliably recognize the sorts of the paper sheets in his or her hand, and hence may accurately and reliably store the paper sheets according to each sort. Incidentally, according to a configuration in which the sorts of the paper sheets stacked in the stacking units 60a to 60d are displayed, it is preferable in that the operator may further reliably recognize the sorts of the paper sheets in his or her hand.
Further, in a configuration in which the removal information includes information on the time at which the paper sheets were removed from the stacking units 60a to 60d, the operator may check the time at which the paper sheets were removed from the stacking units 60a to 60d by, for example, the main display unit 30. For this reason, the operator may reliably recognize the time at which the paper sheets in his or her hand were removed from the stacking units 60a to 60d. Even when the operator forgets the sorts of the paper sheets, the operator may easily remember the sorts of the paper sheets. Incidentally, according to a configuration in which the time at which the paper sheets were removed from the stacking units 60a to 60d and the sorts of the paper sheets are correlated with one another and the sorts of the paper sheets are displayed in addition to the time at which the paper sheets were removed from the stacking units 60a to 60d, it is preferable in that the operator may reliably recognize the sorts of the paper sheets in his or her hand.
Further, in a configuration in which the removal information includes information on the number of the paper sheets removed from the stacking units 60a to 60d, the operator may check the number of the paper sheets removed from the stacking units 60a to 60d by, for example, the main display unit 30.
Further, in the embodiment, the individual display units 31a to 31d notify the stacking units 60a to 60d from which the paper sheets have been removed to the operator in a manner such that the individual display units display “ . . . ” for a predetermined time or turned on with a color different from the color in a normal state in a case where the paper sheets have been removed from the corresponding stacking units 60a to 60d. In the embodiment, since the sorts of the paper sheets to be stacked in the stacking units 60a to 60d are fixed, if the operator may recognize the stacking unit from which the paper sheets have been removed among the stacking units 60a to 60d in this way, the operator may reliably recognize the sorts of the paper sheets in his or her hand. Furthermore, the operator may check the stacking unit from which the paper sheets have been removed among the stacking units 60a to 60d in one glance by such a display on the individual display units 31a to 31d, and hence the working efficiency may be improved.
Third Embodiment
Next, a third embodiment of the invention will be described by referring to FIGS. 6, 7, and 8.
In the first embodiment, a configuration is illustrated in which four stacking units 60a to 60d are provided. However, in the embodiment, a configuration is illustrated in which eight stacking units 60a to 60h are provided. Furthermore, a number of stacking units 60a to 60d are optional as described above. However, for convenience of description, a configuration with four stacking units 60a to 60d is used in the first embodiment, and a configuration with eight stacking units 60a to 60h is used in the third embodiment.
In the embodiment, eight stacking units 60a to 60h are divided into two groups, and the control unit 50 separately outputs the removal information on each group and outputs information on a person in charge allocated to each group. More specifically, eight stacking units 60a to 60h of the embodiment are divided into two groups as the group of four stacking units 60a to 60d from the left side of FIG. 6 and the group of four stacking units 60e to 60h from the right side of FIG. 6. Then, the control unit 50 separately outputs the removal information on four stacking units 60a to 60d from the left side and the removal information on four stacking units 60e to 60h from the right side, and outputs information on a person A in charge of four stacking units 60a to 60d from the left side and a person B in charge of four stacking units 60e to 60h from the right side. Furthermore, eight stacking units 60a to 60h are respectively provided with the corresponding individual display units 31a to 31h. 
Furthermore, in the embodiment, a configuration is illustrated in which the stacking units are divided into two groups, but the invention is not limited thereto. For example, a configuration may be employed in which three or more stacking units are divided into three or more groups.
Further, in a configuration illustrated in FIG. 4 of the first embodiment, the first main display unit 30a or the second main display unit 30b displays each of the removal time, the removal place, the fitness information, and the number of sheets. Further, in a configuration illustrated in FIG. 5 of the first embodiment, the first main display unit 30a or the second main display unit 30b displays each of the removal time, the removal place, the fitness information, the version information, and the number of sheets.
On the contrary, in a configuration illustrated in FIG. 7 of the third embodiment, the first main display unit 30a displays the notice for the person A in charge (“person A in charge” of FIG. 7) and each of the removal time, the removal place, the fitness information, and the number of sheets with respect to the person A in charge. Further, the second main display unit 30b displays the notice for the person B in charge (“person B in charge” of FIG. 7) and each of the removal time, the removal place, the fitness information, and the number of sheets with respect to the person B in charge.
Further, in a configuration illustrated in FIG. 8 of the third embodiment, the first main display unit 30a displays the notice for the person A in charge (“person A in charge” of FIG. 8) and each of the removal time, the removal place, the fitness information, the version information, and the number of sheets with respect to the person A in charge. Further, the second main display unit 30b displays the notice for the person B in charge (“person B in charge” of FIG. 8) and each of the removal time, the removal place, the fitness information, the version information, and the number of sheets with respect to the person B in charge.
Incidentally, in the description above, a configuration is described in which the first main display unit 30a displays the removal information with respect to the person A in charge and the second main display unit 30b displays the removal information with respect to the person B in charge, but the invention is not limited thereto. For example, a configuration may be employed in which the removal information with respect to the person A in charge and the person B in charge is displayed only on the first main display unit 30a or the removal information with respect to the person A in charge and the person B in charge is displayed only on the second main display unit 30b. Further, a configuration may be employed in which the removal information is displayed on an external device such as PC connected to the paper sheet processing apparatus 100 and the removal information is not displayed on the paper sheet processing apparatus 100.
In the third embodiment, the other configurations are substantially the same as those of the first embodiment. In the third embodiment, the same reference numerals are given to the same components as those of the first embodiment, and the detailed description thereof is not be repeated here.
According to the embodiment, the control unit 50 outputs the removal information with respect to four stacking units 60a to 60d from the left side so that the removal information is displayed on the first main display unit 30a, and the control unit 50 outputs the removal information with respect to four stacking units 60e to 60h from the right side so that the removal information is displayed on the second main display unit 30b. For this reason, even when two operators sort the paper sheets by using one paper sheet processing apparatus 100, the respective operators may accurately recognize the removal information with respect to the paper sheets removed from the stacking units 60a to 60h by himself or herself.
Particularly, in the embodiment, since the first main display unit 30a displays the notice for the person A in charge (“person A in charge” of FIG. 6) and the second main display unit 30b displays the notice for the person B in charge (“person B in charge” of FIG. 6), the respective persons in charge may reliably recognize the removal information with respect to the paper sheets removed from the stacking units 60a to 60h by himself or herself.
Incidentally, a configuration of the third embodiment may be used in the second embodiment. That is, the control unit 50 of the third embodiment may cause the respective stacking units 60a to 60d to stack the paper sheets thereon by appropriately changing the sorts of the paper sheets to be stacked in the stacking units 60a to 60d as in the first embodiment, and may also cause the respective stacking units 60a to 60d to stack the paper sheets thereon by fixing the sorts of the paper sheets to be stacked in the stacking units 60a to 60d as in the second embodiment.
Furthermore, in the embodiment, the same effects as those of the first embodiment and the second embodiment may be obtained in addition to the above-described effect. However, in the embodiment, the description of these effects will not be made so as to avoid the repetitive description thereof.
Incidentally, the description of the embodiments above and the disclosure of the drawings are merely examples for describing the invention disclosed in claims, and the invention disclosed in claims is not limited to the description of the embodiment above or the disclosure of the drawings.
