     In the above-mentioned medicine packing apparatus according to the present invention, the printing means is capable of printing a predetermined information piece including the production-history information piece on the packaging sheet based on print data issued from the control means, and when the separate packing is performed, among the medicines to be packed as one dose, print data of a pre-delivered medicine that has been delivered by the time when the medicine shortage occurs and print data of a post-delivered medicine that has been delivered after the medicine shortage occurs are issued from the control means. 
     In the medicine packing apparatus according to the present invention, it is desired that the printing means be arranged on an upstream side in a feeding direction of the packaging sheet with respect to the packing means, and at or after a timing when the medicine is delivered from the medicine delivery means, an information piece of the delivered medicine be printed by the printing means. 
     Further, in the medicine packing apparatus according to the present invention, it is preferred that the printing means be arranged on an upstream side in a flow direction of the packaging sheet fed from the packaging-sheet feeding means with respect to the packing means, that the medicine preparation means include a turnable division formation body, and have an opening through which the medicine is delivered from the medicine preparation means and a hole through which the medicine delivered from the medicine delivery means is charged, that the division formation body include a plurality of divisions in a circumferential direction, each of which is capable of stocking the medicine in a pack unit, that, when the division formation body turns so that each of the plurality of divisions comes to a position corresponding to the hole, the medicine be allowed to be charged into each of the plurality of divisions through the hole, that, when the division formation body turns so that each of the plurality of divisions comes to a position corresponding to the opening, the medicine in each of the plurality of divisions be delivered, and that the hole be provided at a position on an upstream side in a turning direction of the division formation body with respect to the opening. 
     When the medicine packing apparatus according to the present invention is structured as described above, it is preferred that a length of a path, which the packaging sheet passes, between the printing means and the packing means be set to be n times as large as a length of the packaging sheet required for packaging of the medicines corresponding to one pack, and that the hole be provided at a position on the upstream side by an amount corresponding to n or more divisions in the turning direction of the division formation body with respect to the opening. 
     In the medicine packing apparatus according to the present invention, it is desired that the production-history information piece include an information piece including at least any one of a production lot number of the medicine, a production date of the medicine, and a use-by date of the medicine. 
     Advantageous Effects of Invention 
     In the medicine packing apparatus of the present invention, the control means is capable of specifying the production-history information pieces based on the production histories of the medicines delivered from the medicine delivery means. Thus, when being delivered from the medicine delivery means, the medicines having the different production-history information pieces while being of the same type are packed separately into different packs based on the different production-history information pieces. Further, in the medicine packing apparatus of the present invention, the production-history information pieces of the medicines specified by the control means are printed on the packaging sheets by the printing means. Thus, according to the medicine packing apparatus of the present invention, the medicines can be packed so that the relations between the medicines and the production-history information pieces can be clearly understood. 
     Further, in the case where the medicine, which is delivered from the medicine delivery means as medicines to be packed as one dose, includes the medicine having the different production-history information piece while being of the same type, those medicines are packed separately into different packs based on the respective production-history information pieces thereof. With this, those medicines having the different production-history information pieces while being of the same type are reliably prevented from being mixed into a single pack. Thus, according to the present invention, it is possible to provide a medicine packing apparatus which enables the correspondences between the medicines and the production-history information pieces to be easily and reliably understood. 
     According to the medicine packing apparatus of the present invention, the medicine delivery means includes the plurality of medicine feeders each capable of accommodating and delivering the medicine. When the actual delivery number of the medicines delivered from the specified medicine feeder is smaller than the designated delivery number of the medicines designated based on the prescription data, it is judged that the medicine shortage occurs in the specified medicine feeder. As a result, the medicines to be packed as one dose are packed separately into the different packs based on the respective production-history information pieces thereof (separate packing). Thus, according to the medicine packing apparatus of the present invention, even when the shortage occurs in the medicine feeder and the medicines having the different production-history information pieces while being of the same type are delivered as one dose, the medicines having the different production-history information pieces while being of the same type are reliably prevented from being mixed into a single pack. Thus, according to the present invention, it is possible to provide a medicine packing apparatus which enables the correspondences between the medicines and the production-history information pieces to be easily and reliably understood. 
     Further, according to the medicine packing apparatus of the present invention, when the separate packing is performed, among the medicines to be packed as one dose, the print data of the pre-delivered medicine that has been delivered by the time when the medicine shortage occurs and the print data of the post-delivered medicine that has been delivered after the medicine shortage occurs are issued from the control means. Thus, information pieces including the production-history information pieces are printed on both a bag packing the pre-delivered medicine and a bag packing the post-delivered medicine. As a result, the correspondences between the medicines and the production-history information pieces are clarified. 
     According to the medicine packing apparatus of the present invention, the printing means is arranged on the upstream side in the feeding direction of the packaging sheet with respect to the packing means, and at or after the timing when the medicine is delivered from the medicine delivery means, the information piece of the delivered medicine is printed by the printing means. Thus, the packaging sheet and the like are prevented from being wasted. 
     As described above, in the medicine packing apparatus of the present invention, the length of the path, which the packaging sheet passes, between the printing means and the packing means is set to be n times as large as the length of the packaging sheet required for packaging of the medicines corresponding to one pack. Further, the medicine preparation means provided to the medicine packing apparatus of the present invention includes the plurality of divisions so that the medicines charged in the plurality of divisions can be delivered in a predetermined order. Thus, in the medicine packing apparatus of the present invention, the medicines delivered from the above-mentioned division X are packed with the packaging sheet which undergoes printing by the printing means at a timing preceding a timing when the medicines stocked in one division X of the plurality of divisions are delivered by the time period required for delivery of the medicines corresponding to n divisions (n packs) from the medicine preparation means toward the packing means. That is, in the medicine packing apparatus of the present invention, medicines to be packed are charged into the division X at a timing preceding performing printing corresponding to the division X onto the packaging sheet, and a timing when the medicines prepared in the division X are delivered into a packing portion and a timing when a part of the packaging sheet, at which information pieces such as production-history information pieces of the medicines accommodated in the division X, comes to the packing portion correspond to each other. Thus, in the medicine packing apparatus of the present invention, the packaging sheet undergoes printing on a premise that the medicines to be packed have been charged in the division X, and hence whether or not the medicines to be packed have been correctly charged can be easily monitored. Further, in the medicine packing apparatus of the present invention, printing is not performed on the packaging sheet in case of a failure of medicine supply, and hence the packaging sheet and the like are prevented from being wasted by that much. Note that, the structure of the present invention can be suitably employed on a premise that lengths of the packaging bags formed of the packaging sheet are constant, and cannot be employed when the lengths of the packaging bags vary. 
     When the medicine packing apparatus of the present invention is structured as described above, it is preferred to set the following as a condition for performing printing on the packaging sheet by the printing means: the medicines have been charged into the division X by the timing preceding the timing when the medicines stocked in the one division X of the plurality of divisions in the medicine preparation means are delivered by the time period required for delivery of the medicines corresponding to the n divisions from the medicine preparation means. 
     In the medicine packing apparatus of the present invention, the medicines are delivered from the medicine delivery means into the division X at the timing preceding the timing when the medicines stocked in the division X in the medicine preparation means are delivered by the time period or more required for delivery of the medicines corresponding to the n divisions from the medicine preparation means. Thus, in the medicine packing apparatus of the present invention, the information pieces corresponding to the division X are printed on the packaging sheet under a state in which the medicines have been reliably charged in the division X. Thus, according to the medicine packing apparatus of the present invention, whether or not the medicines to be packed have been correctly packed can be easily monitored, and even when the failure of medicine supply occurs, waste of the packaging sheet and the like involved therewith can be eliminated. 
     Further, when the above-mentioned production-history information piece includes the information piece including at least any one of the production lot number of the medicine, the production date of the medicine, and the use-by date of the medicine, production histories of the medicines can be traced, and the use-by dates of the medicines can be easily understood.

     Description of Embodiment 
     Next, description is made in detail of a medicine packing apparatus  10  according to an embodiment of the present invention with reference to figures. Note that, the present invention is not limited to the embodiment. 
     The medicine packing apparatus  10  packs medicines with packaging sheets P according to prescription, and delivers the medicines. As illustrated in  FIG. 1 , the medicine packing apparatus  10  includes a main unit  20  having a rectangular-parallelepiped shape. As illustrated in  FIG. 2 , the medicine packing apparatus  10  includes medicine delivery means  30  and medicine preparation means  50  which are provided in the main unit  20 . Further, as illustrated in  FIG. 3 , on a lower side of the main unit  20 , there are provided packaging-sheet feeding means  60 , printing means  70 , packing means  80 , and a packaging-sheet sending mechanism  90 . Further, as illustrated in  FIG. 7 , the medicine packing apparatus  10  includes control means  100 . 
     The medicine delivery means  30  is provided to store medicines and to appropriately discharge the medicines according to prescription so as to supply the medicines to the packing means  80 . The medicine delivery means  30  includes a supply portion  32 . The supply portion  32  has such a function as to store the medicines and discharge the medicines according to prescription toward the medicine preparation means  50 . Further, the medicine preparation means  50  has such a function as to stock the medicines supplied from the supply portion  32  by an amount to be packed in the same pack, and to successively discharge the medicines by such an amount toward the packing means  80 . 
     Specifically, as illustrated in  FIG. 2 , the supply portion includes a feeder-type supply portion  36  and a manual-distribution-type supply portion  38  as means for supplying the medicines. In addition, the supply portion  32  includes a standby hopper  40 , a collection hopper  42 , and a manual-distribution hopper  44 . The feeder-type supply portion  36  includes a large number of cassette-type medicine feeders  46 , and is capable of discharging, according to prescription, the medicines prepared in the medicine feeders  46  in advance. The standby hopper  40  is arranged below the feeder-type supply portion  36 . The standby hopper  40  is openable and closable by movement control from the control means  100 , and collects, in a close state, the medicines delivered from the medicine feeders  46  by such an amount as to be packed in the same pack and then is opened through activation of a power source (not shown), thereby being capable of discharging the collected medicines at one time. The medicines discharged from the standby hopper  40  are supplied to the medicine preparation means  50  through intermediation of the collection hopper  42  provided below the standby hopper  40 . Further, the feeder-type supply portion  36  is provided with a medicine discharge sensor  46   a  for detecting discharge of the medicines for each of the medicine feeders  46 . 
     Further, the manual-distribution-type supply portion  38  is prepared separately from the feeder-type supply portion  36 , and is used for supplying medicines unsuitable to delivery from the feeder-type supply portion  36  and medicines not prepared in the feeder-type supply portion  36  so that those medicines are packed. Similarly to the feeder-type supply portion  36 , the manual-distribution-type supply portion  38  is capable of supplying the medicines to a medicine-preparation-means- 50  side. The manual-distribution-type supply portion  38  includes a manual-distribution unit  48 . Although being normally accommodated in the main unit  20 , the manual-distribution unit  48  can be used by being drawn out to a front side of the main unit  20  when necessary as illustrated in  FIG. 1 . As illustrated in  FIG. 1 , the manual-distribution unit  48  is provided with a plurality of cells  48   a  which are arranged in a matrix-like manner and capable of collectively accommodating medicines to be packed in a single pack. In the manual-distribution unit  48 , the cells  48   a  are opened one by one so that the medicines can be supplied in pack units to the medicine-preparation-means- 50  side. When the manual-distribution unit  48  is brought into the drawn-out state as illustrated in  FIG. 1 , such a state is reached that the medicines can be replenished into the cells  48   a . Further, when the manual-distribution unit  48  is brought into such a state as to be accommodated in the main unit of the medicine packing apparatus  10 , the manual-distribution hopper  44  comes below the manual-distribution unit  48 , and then such a state is reached that the medicines prepared in the cells  48   a  can be supplied to the medicine-preparation-means- 50  side through intermediation of the manual-distribution hopper  44  provided below the manual-distribution unit  48 . 
     As illustrated in  FIGS. 4 and 5 , in the medicine preparation means  50 , a disc-like division formation body  52  is accommodated in a space constituted by a medicine-preparation-portion main unit  54   a  and a lid  54   b . The division formation body  52  includes a division  52   a  for stocking the medicines. The division formation body  52  is capable of turning about a support shaft  52   b  by receiving power from a power source  56  provided in the medicine-preparation-portion main unit  54   a . The division  52   a  of the division formation body  52  includes a plurality of divisions  52   a  in a circumferential direction. As described below, in order that the medicines are prepared at a stage preceding, by a time period or more required for packing of the medicines corresponding to n packs (three packs in this embodiment), a timing when the medicines are packed in the packing means  80 , the division formation body  52  is required to include at least n or more divisions  52   a . Therefore, the division formation body  52  is required to include at least three divisions  52   a . In this embodiment, the division formation body  52  is provided with six divisions  52   a , and hence the medicines can be prepared at the stage preceding the time period or more required for packing of the medicines corresponding to n packs (three packs in this embodiment). 
     Each of the divisions  52   a  is open on a top surface side. Further, each of the divisions  52   a  is provided at such a position as to be communicable to charging ports  54   c  and  54   d  provided in the lid  54   b  when the division formation body  52  is turned about the support shaft  52   b . Still further, as illustrated in  FIG. 3 , the collection hopper  42  and the manual-distribution hopper  44  are connected respectively to the charging ports  54   c  and  54   d . Thus, when the division formation body  52  is turned, the medicines supplied from the feeder-type supply portion  36  and the manual-distribution-type supply portion  38  can be supplied into the divisions  52   a  through the charging ports  54   c  and  54   d.    
     In the division formation body  52 , each of the divisions  52   a  is provided with a shutter  52   c  independently openable and closable. The division formation body  52  is capable of discharging downward the medicines accommodated in each of the divisions  52   a  from a bottom side by opening the shutter  52   c . Further, each of the divisions  52   a  is provided at such a position as to be capable of passing above an opening  54   e  (refer to  FIG. 5 ) provided in a bottom surface of the medicine-preparation-portion main unit  54   a  when the division formation body  52  is turned about the support shaft  52   b . Still further, as illustrated in  FIGS. 2 and 3 , a discharge hopper  58  is provided below the opening  54   e  so that the medicines discharged through the opening  54  can be supplied to a packing-means- 80  side. Thus, when turning the division formation body  52  and opening the shutter  52   c  provided to the division  52   a  positioned above the opening  54   e , the medicines accommodated in the division  52   a  can be supplied to the packing-means- 80  side through the opening  54   e.    
     Here, the above-mentioned medicine preparation means  50  is capable of delivering the medicines in pack units (every division  52   a ) by turning in a fixed direction as indicated by arrows of  FIG. 12  so as to successively move the divisions  52   a  to a position corresponding to the medicine-delivery opening  54   e . That is, the medicines accommodated in each of the divisions  52   a  are delivered at such a timing as to reach the opening  54   e . Thus, the above-mentioned collection hopper  42  and manual-distribution hopper  44  are capable of charging medicines into the division  52   a  at a timing preceding, by a time period or more required for packing of three packs, delivery of the medicines through the medicine-delivery opening  54   e . In this embodiment, medicines are charged from the collection hopper  42  into the division  52   a  at a timing preceding, by a time period required for packing of five packs, delivery of the medicines through the opening  54   e , and other medicines are charged from the manual-distribution hopper  44  into the division  52   a  at a timing preceding, by a time period required for packing of four packs, delivery of the medicines through the opening  54   e.    
     As illustrated in  FIG. 3 , below the above-mentioned medicine preparation means  50 , there are provided devices such as the packaging-sheet feeding means  60 , the printing means  70 , the packing means  80 , and the packaging-sheet sending mechanism  90 . The packaging-sheet feeding means  60  is a mechanism for pulling out and sending the sheet-like elongated packaging sheet P made of a thermal adhesive sheet wound around a roll shaft  62  to the packing means  80 . The packaging sheet P pulled out by the packaging-sheet feeding means  60  is successively fed to the packing means  80  via the printing means  70  as indicated by an arrow of  FIG. 3 . 
     The printing means  70  is provided to perform printing on the packaging sheet P sent out by the packaging-sheet feeding means  60 . As illustrated in  FIG. 3 , the printing means  70  is provided at a position on an upstream side in a flow direction of the packaging sheet P with respect to the above-mentioned packing means  80 . Under a state in which an operation of feeding the packaging sheet P for packing of the medicines is performed, a length of the packaging sheet P existing between respective positions of the printing means  70  and the packing means  80 , that is, a length of a path, which the packaging sheet P passes, between the printing means  70  and the packing means  80  is set to be n times (three times in this embodiment) as large as a length L of a longitudinal part of a packaging bag V formed as described below. Thus, a timing when printing is performed on the packaging sheet P in the printing means  70  corresponds to a timing when the medicines are packed in the packing means  80 , that is, a timing preceding the timing when the medicines are delivered through the opening  54   e  of the medicine preparation means  50  toward the packing means  80  by the time period required for packing of the medicines corresponding to n packs (three packs in this embodiment). 
     Here, as described above, in this embodiment, medicines are charged from the collection hopper  42  and the manual-distribution hopper  44  into the division  52   a  at the timing preceding, by the time period or more required for packing of three packs, the timing when medicines are delivered through the opening  54   e  of the medicine preparation means  50  toward the packing means  80 . Thus, after the medicines are charged into the division  52   a , information pieces of the medicines are printed on the packaging sheet P. 
     In more detail, as illustrated in  FIG. 12 , in this embodiment, the division formation body  52  are provided with six divisions  52   a . Description is made, by way of example, of a division  52   a  denoted by number  1  in  FIG. 12  (hereinafter, also referred to as “division X”). Medicines stocked in the one division X of the plurality of divisions  52   a  are delivered at a timing when the division formation body  52  is turned as illustrated in  FIG. 12(   d ) to the position at which the medicine-delivery opening  54   e  is provided. Meanwhile, medicines are charged from the feeder-type supply portion  36  into the division X at a stage illustrated in  FIG. 12(   a ), that is, at a timing preceding the timing when the medicines are delivered from the division X by a time period required for delivery of medicines corresponding to five packs. Further, medicines are charged from the manual-distribution-type supply portion  38  into the division X at a stage illustrated in  FIG. 12(   b ), that is, at a timing preceding the timing when the medicines are delivered from the division X by a time period required for delivery of medicines corresponding to four packs. As described above, the information pieces of the medicines in the division X are printed on the packaging sheet P at a stage preceding, by the time period required for packing of three packs, the timing when the medicines are delivered from the division X. Thus, by the time when the information pieces of the medicines in the division X are printed on the packaging sheet P, charge of the medicines from the feeder-type supply portion  36  and the manual-distribution-type supply portion  38  into the division X can be completed. 
     The packing means  80  includes a packaging-sheet folding member  82  and a pressure-bonding device  84 . The packing means  80  receives the packaging sheet P on which predetermined information pieces have been printed in the printing means  70  so as to pack the medicines in pack units with use of the packaging sheet P. The packaging-sheet folding member  82  is a bar-like member applied to a substantially central part in a short direction (width direction) of the packaging sheet P fed from a printing-means- 70  side, and is capable of folding the packaging sheet P in two at the substantially central part in the short direction (width direction) thereof as illustrated in  FIG. 6(   a ) when the packaging sheet P is sent to a downstream side in this state. The pressure-bonding device  84  is capable of forming the packaging bag V by pressure-bonding the packaging sheet P which has been double-plied by being folded by the packaging-sheet folding member  82 . As illustrated in  FIGS. 6(   b ) and  11  to  15 , the packaging bags V are formed continuously in a longitudinal direction of the packaging sheet P (sending direction of the packaging sheet P). 
     The pressure-bonding device  84  is capable of pressure-bonding the packaging sheet P in the following two separate stages: such a stage as to seal by pressure-bonding, as illustrated in  FIG. 6(   a ), a short side of the packaging bag V (transverse side in the width direction of the packaging sheet P); and such a stage as to seal by pressure-bonding, as illustrated in  FIG. 6(   b ), rest sides of the packaging bag V, that is, a long side (side extending in the longitudinal direction of the packaging sheet P) and another short side parallel to the short side sealed in  FIG. 6(   a ). Further, as illustrated in  FIG. 6(   a ), at the stage in which the short side of the packaging bag V is sealed by the pressure-bonding device  84 , such a state is reached that the discharge hopper  58  is inserted in the packaging bag V in a semi-bag shape in which the long-side part has not yet been sealed. Thus, the medicines can be packed in the packaging bag V by sealing in the following manner: at the stage in which the short-side parts of the packaging bag V are sealed by the pressure-bonding device  84 , the medicines are supplied from the medicine-preparation-means- 50  side into the packaging bag V in the semi-bag shape, and then the long side of the packaging bag V is sealed by the pressure-bonding device  84  as illustrated in  FIG. 6(   b ). The packaging sheet P with which the medicines are packed in this manner is fed by the packaging-sheet sending mechanism  90  provided on a further downstream side with respect to the packing means  80  in a sending direction of the packaging sheet P so as to be delivered from the main unit  20  of the medicine packing apparatus  10  toward an outside. 
     As illustrated in  FIG. 7 , the control means  100  mainly includes a control portion  102 , and an input device  104  and a PC terminal  106  are connected to the control portion  102  so as to be capable of data communication in a wired or wireless manner. The control portion  102  controls overall operations of the medicine packing apparatus  10 , and may include a digital circuit using a CPU. The control portion  102  includes package control means  108 , print control means  110 , and feeder-information memory means  112 . The package control means  108  has such a function as to issue operation command signals, based on prescription data input from the outside, to the above-mentioned medicine delivery means  30 , the standby hopper  40 , the medicine preparation means  50 , the printing means  70 , the packing means  80 , the packaging-sheet sending mechanism  90 , and the like so as control a series of packaging operations. Further, the print control means  110  is provided for performing printing on the packaging sheet P by sending at a predetermined timing print data PD received from the PC terminal  106  described in detail below to the printing means  70  so as to activate the printing means  70 . 
     The feeder-information memory means  112  is capable of building a database (hereinafter, also referred to as “medicine specification database” DB) in which information pieces for specification of the feeder supply portions  36  constituting the medicine delivery means (hereinafter, also referred to as “feeder-specification information pieces” FD) and information pieces for specification of the feeder-type supply portions  36  and types of the medicines prepared therein are correlated with each other, and is capable of recording the correlated information pieces. The feeder-specification information pieces FD may include address information pieces indicating attachment positions of the feeder supply portions  36  and a unique ID number of each of the feeder supply portions  36 . In this embodiment, the above-mentioned address information pieces indicating the attachment positions of the feeder supply portions  36  are employed as the feeder-specification information pieces FD. The medicine specification database DB includes the information pieces obtained by correlation of the address information pieces of the feeder supply portions  36  (feeder-specification information pieces FD) and the information pieces for specification of the types of the accommodated medicines. Thus, with reference to the medicine specification database DB, it can be understood that a medicine A (A=type of medicine) is prepared in a feeder supply portion  36  allocated with an address number N (N=natural number). 
     The input device  104  may include a touch-panel type input device, a conventional well-known keyboard, a mouse, or buttons. In this embodiment, the touch-panel type input device is employed as the input device  104 . The input device  104  is used, at the time of loading of the medicines into the feeder-type supply portions  36 , for input of information pieces which fluidly change every time the medicines are loaded into the feeder-type supply portions  36 , such as information pieces of production histories of the medicines to be loaded (hereinafter, also referred to as “production-history information pieces” MC) and the loading number of the medicines. The production-history information pieces MC may include one or a plurality of information pieces selected from lot numbers of the medicines, production dates of the medicines, use-by dates of the medicines, and the like. In this embodiment, the lot numbers of the medicines are employed as the production-history information pieces MC. The information pieces such as the production-history information pieces MC and the loading number of the medicines input via the input device  104  are transmitted to the PC terminal  106  by way of the control portion  102  so as to be recorded in a memory device such as a hard disk drive prepared in the PC terminal  106 . 
     The PC terminal  106  includes a conventional well-known personal computer, and can be connected to a host terminal or the like (not shown) when necessary. In addition to such a function as to record the above-mentioned information pieces such as the production-history information pieces MC and the loading number of the medicine, the PC terminal  106  has a function as an input terminal for prescription data. Specifically, the PC terminal  106  enables direct input of the prescription data through operation by an operator. Further, when an external device such as the host terminal (not shown) is connected to the PC terminal  106 , the prescription data can be input from an external-device side. 
     The control means  100  is configured as described above, and capable of packing the medicines under control by the package control means  108 . In addition, the control means  100  is capable of confirming the types of the medicines delivered from the medicine feeder  46  under driving through access to the feeder-information memory means  112 , and reading out the production-history information pieces MC of the medicines from the memory device of the PC terminal  106  so as to confirm the production-history information pieces MC. That is, in this embodiment, the control means  100  exerts a function as production-history specifying means for specifying the production-history information pieces MC. 
     Next, description is made in detail of an operation of the medicine packing apparatus  10  of this embodiment with reference to flowcharts illustrated in  FIGS. 8 to 10 . First, in Step  1 - 1 , the medicine packing apparatus  10  confirms whether or not prescription data has been input to the PC terminal  106  of the control means  100 . When it is confirmed that the prescription data has been input, a control flow proceeds to Step  1 - 2 , and the feeder-information memory means  112  is referred to in the control portion  102 . Then, the medicine feeder  46  in which a medicine to be prescribed is accommodated (hereinafter, also referred to as “selected feeder”  46 ) is determined, and the operation command signal is issued from the control portion  102  to the medicine feeder  46 . Further, in Step  1 - 2 , print data PD used for printing on the packaging sheet P in Step  1 - 5  described below is created. 
     When the selected feeder  46  starts to be driven based on the operation command signal in Step  1 - 2 , the medicine is delivered. In this case, a medicine detecting signal issued from the medicine discharge sensor  46   a  provided to the selected feeder  46  under driving is received in the control portion  102 , and the medicine delivery number is calculated based on the detecting signal (Step  1 - 3 ). Further, in Step  1 - 4 , it is confirmed whether or not delivery of the medicine in the selected feeder  46  has been completed. Specifically, it is confirmed whether or not the delivery of the medicine has been completed through comparison of the medicine delivery number calculated in Step  1 - 3  and the delivery number designated in the prescription data received in Step  1 - 1 . When it is judged that the delivery of the medicine has not yet been completed in Step  1 - 4 , the control flow is returned to Step  1 - 2 , and a medicine delivery operation is continued. Meanwhile, when it is judged that the medicine delivery operation has been completed in Step  1 - 4 , the control flow proceeds to Step  1 - 6 , and the division formation body  52  is turned in a normal direction by an amount corresponding to one division. After that, the control flow proceeds to Step  1 - 6 . 
     In Step  1 - 6 , the print data PD created in the above-mentioned Step  1 - 2  and issued from the PC terminal  106  is transmitted to the printing means  70  by way of the control portion  102 , and then printing is performed on the packaging sheet P. In this case, in addition to information pieces such as a patient&#39;s name and a dose timing, information pieces such as names, numbers, and the production-history information pieces MC of the medicines that have been delivered in the flow corresponding to from Steps  1 - 2  to  1 - 4  described above are printed on the packaging sheet P. Specifically, when the name of the medicine is A and the production-history information piece MC is a lot number # 01 , those information pieces are printed as illustrated in  FIG. 6 . Alternatively, the number of the medicines and the patient&#39; s name may be appropriately printed. 
     When the printing is completed in Step  1 - 6 , the control flow proceeds to Step  1 - 7 , and the medicine prepared in the flow corresponding to from Steps  1 - 2  to  1 - 4  is packed in the packaging sheet P (refer to  FIG. 6(   b )). After that, the control flow proceeds to Step  1 - 8 , and it is confirmed whether or not there is a medicine to be subsequently packed. When there is a medicine to be subsequently packed, the control flow is returned to Step  1 - 2 , and a medicine packing operation is continued. Meanwhile, when there is no medicine to be subsequently packed, a series of the above-mentioned control flow is completed. 
     Meanwhile, when it is judged that the medicine necessary for packing has not yet been delivered from the selected feeder  46  in Step  1 - 4  described above, the control flow proceeds to Step  1 - 9 . In Step  1 - 9 , the reason why it is judged that the delivery has not yet been completed in Step  1 - 4  is confirmed to be caused by medicine shortage in the selected feeder  4   6  or mere incompletion of the medicine delivery. Specifically, when a state in which the medicines are not detected by the medicine discharge sensors  46   a  continues over a predetermined time period in spite of incompletion of discharge of the medicines by the number corresponding to one dose, it is judged that the medicine shortage has occurred. Here, when it is judged that the medicine delivery has not yet been completed, that is, when it is judged that the medicines are being delivered, the control flow is returned to Step  1 - 2 . Until the medicine delivery of a required amount is completed, the operation of the medicine feeder is continued. 
     In contrast, when the reason why it is judged that the delivery has not yet been completed in Step  1 - 4  is the medicine shortage in the selected feeder  46 , the control flow proceeds to Step  1 - 10 , and a separate-packing operation is performed. Specifically, when the control flow proceeds to Step  1 - 10 , control according to subroutines illustrated in  FIGS. 9 and 10  is started. In the subroutine illustrated in  FIG. 9 , first, in Step  2 - 1 , it is confirmed whether or not there is the medicine feeder  46  capable of delivering a medicine to be delivered (hereinafter, also referred to as “alternative feeder”  46 ). Here, the control flow proceeds to Step  2 - 2  when there is the alternative feeder  46 , and proceeds to Step  3 - 1  described in detail below when there is no alternative feeder  46 . 
     When the control flow proceeds to Step  2 - 2 , as are printed on a packaging bag V 1  of  FIG. 11(   b ), in addition to the information pieces such as the patient&#39;s name and the dose timing of the medicines, there are printed information pieces such as a name, the number, and the production-history information piece MC of a medicine that has already been delivered from the selected feeder  46  (pre-delivered medicine). Specifically, when the control flow proceeds to a flow corresponding to Step  2 - 1  and subsequent Steps, as illustrated in  FIG. 11(   b ), the pre-delivered medicine and a medicine which is short in supply in pre-delivery (post-delivered medicine) are packed in different packaging bags V 1  and V 2 . Thus, when the control flow proceeds to Step  2 - 2 , the print data PD that has been prepared by the print control means  110  at a timing preceding Step  2 - 2  is discarded. Then, print data which reflects information pieces such as names, the numbers, and production-history information pieces MC of medicines to be accommodated in the packaging bags V 1  and V 2  is prepared. In Step  2 - 2 , based on the print data PD re-prepared by the print control means  110 , the information pieces of the pre-delivered medicine to be packed into the packaging bag V 1  are printed. 
     Further, in Step  2 - 3 , in response to the control command signal from the control portion  102 , the division formation body  52  turns in the normal direction by the amount corresponding to one division  52   a . With this, the division  52   a  accommodating the medicine delivered from the selected feeder  46  moves in the circumferential direction of the division formation body  52 , and such a state is reached that a medicine can be charged into next division  52   a . That is, by turning of the division formation body  52  in Step  2 - 3 , the medicine delivered from the selected feeder  46  and medicines to be delivered in subsequent Steps in the control flow can be accommodated in separate divisions  52   a.    
     Specifically, when the production-history information pieces MC of the medicines to be packed as one dose (one unit) are same as each other, the medicines are collectively charged into the division  52   a  (division  52   a  denoted by number  1  in the figure) of the division formation body  52  as illustrated in  FIG. 12(   a ). In contrast, when medicine shortage occurs in a case where a plurality of medicines of the same type are packed as one dose as illustrated in  FIG. 12(   a ), after the pre-delivered medicine is charged into the division  52   a  (division  52   a  denoted by number  2  in the figure) as illustrated in  FIG. 12(   b ), the division formation body  52  is turned in the normal direction by the amount corresponding to one division  52   a  as indicated by the arrows of the figure (refer to  FIG. 12(   c )). With this, the pre-delivered medicines and medicines which are to be delivered in subsequent Steps and have different production-history information pieces MC are prevented from being mixed with each other in one division  52   a  (refer to  FIG. 12(   d )). 
     When turning of the division formation body  52  is completed in Step  2 - 3 , the control flow proceeds to Step  2 - 4 . Then, the alternative feeder  46  is determined, and an operation command signal is issued from the control portion  102  to the alternative feeder  46 . With this, a medicine which is short in supply in the delivery operation of the medicine from the selected feeder  46  can be delivered from the alternative feeder  46 . As illustrated in  FIGS. 12(   c ) and ( d ), the medicine delivered from the alternative feeder  46  is charged into different division  52   a  (division  52   a  denoted by number  3  in the figure) from the divisions  52   a  for the pre-delivered medicines. Further, when the alternative feeder  46  is driven in Step  2 - 4 , the control flow proceeds to Step  2 - 5 , and the medicine delivery number is calculated in the control portion  102  based on the detecting signal issued from the medicine discharge sensor  46   a  provided to the alternative feeder  46 . 
     Here, the print data PD which has been created in Step  1 - 2  described above is prepared on a premise that normal packing is performed (Step  1 - 7 ). Thus, in order to perform separate packing, it is necessary to re-prepare the print data PD so that printing corresponding to the separate packing is performed. Thus, in parallel with determination of the alternative feeder  46  in Step  2 - 4 , the print data PD that has been prepared in Step  1 - 2  is deleted and re-prepared. 
     When it is judged that the medicine delivery has not yet been completed in Step  2 - 6  as a result of the calculation in Step  2 - 5 , the control flow proceeds to Step  2 - 10 . Then, the reason why it is judged that the medicine delivery has not yet been completed is confirmed to be caused by medicine shortage in the alternative feeder  46  or the fact that the medicine delivery is being carried out. Specifically, as in the case of Step  1 - 9  described above, when a state in which the medicines are not detected by the medicine discharge sensors  46   a  continues over a predetermined time period in spite of incompletion of discharge of the medicines corresponding to one dose, it is judged that the medicine shortage has occurred. Here, when it is judged that the medicine delivery is being carried out, the control flow is returned to Step  2 - 4 , and the medicine delivery in the alternative feeder  46  is continued. Meanwhile, when it is judged that the medicine delivery has not yet been completed owing to the medicine shortage in the alternative feeder  46 , the control flow is returned to Step  2 - 1 . In this case, when there is still another medicine feeder  46  alternative to the alternative feeder  46 , the control flow proceeds to Step  2 - 2  as in the above-mentioned case. Meanwhile, when it is judged that there are no alternatives to the alternative feeder  46 , the control flow proceeds to Step  3 - 1 . 
     Meanwhile, when it is confirmed in Step  2 - 6  that the medicine delivery in the alternative feeder  46  has been completed, the control flow proceeds to Step  2 - 7 . In Step  2 - 7 , as are printed on the packaging bag V 2  in  FIG. 11(   b ), in addition to the information pieces such as the patient&#39;s name and the dose timing, there are printed information pieces such as a name and the production-history information piece MC of the medicine delivered from the alternative feeder  46  (post-delivered medicine). Specifically, in the example illustrated in  FIG. 11(   b ), a lot number corresponding to the production-history information piece MC of the medicine A delivered from the alternative feeder  46  is # 02 , and hence a name of the medicine A and the lot number # 02  are printed on the packaging bag V 2 . 
     After that, when the control flow proceeds to Step  2 - 8 , first, the medicine delivered from the alternative feeder  46  is packed with the packaging sheet P (packaging bag V) that has undergone printing in Step  2 - 2 . Specifically, in the example illustrated in  FIG. 11(   b ), the medicine A of the lot number # 01 , which is delivered from the selected feeder  46 , is packed into the packaging bag V 1 . Further, when packing of the medicines in Step  2 - 8  is completed, the control flow proceeds to Step  2 - 9 , and the medicine delivered from the alternative feeder  46  is packed with the packaging sheet P (packaging bag V) that has undergone printing in Step  2 - 7 . Specifically, in the example illustrated in  FIG. 11(   b ), the medicine A of the lot number # 02 , which is delivered from the alternative feeder  46 , is packed into the packaging bag V 2  formed continuously with the packaging bag V 1 . With this, such a state is reached that the medicine delivered from the selected feeder  46  and the medicine delivered from the alternative feeder  46  are respectively packed in the separate packaging sheets P (packaging bags V). 
     When it is judged in Step  2 - 1  described above that there is no alternative feeder  46 , the control flow proceeds to Step  3 - 1 . In Step  3 - 1 , first, in addition to the information pieces such as the patient&#39;s name and the dose timing of the medicines, there are printed information pieces such as a name and the production-history information piece MC of a medicine that has already been delivered (pre-delivered medicine). After that, the control flow proceeds to Step  3 - 2 , and the division formation body  52  turns in the normal direction by the amount corresponding to one division  52   a  in response to the control command signal from the control portion  102 . With this, as in the case of Step  2 - 3  described above, the division  52   a  accommodating the medicine that has been already delivered moves in the circumferential direction of the division formation body  52  from such a position as to be capable of receiving the medicine from the collection hopper  42 . Thus, such a state is reached that medicines to be delivered from the collection hopper  42  in subsequent Steps in the control flow can be charged into another division  52   a.    
     When the division formation body  52  turns in Step  3 - 2  described above, the control flow proceeds to Step  3 - 3 . In Step  3 - 3 , when such a state is reached that a loading operation of a medicine into the selected feeder  46  has been completed through input of the production-history information piece MC of the medicine that has been loaded in the selected feeder  46  and the loading number of the medicines into the PC terminal  106  with use of the input device  104  such as a touch panel, the control flow proceeds to Step  3 - 4 , and the selected feeder  46  is determined and restarts to be driven. Further, in parallel with the determination and drive-restart of the selected feeder  46 , the print data PD that has been prepared in Step  1 - 2  described above is deleted, and new print data PD is prepared. 
     When driving of the selected feeder  46  is restarted in Step  3 - 4 , the control flow proceeds to Step  3 - 5 . In Step  3 - 5 , the delivery number of the medicines delivered from the selected feeder  46  is calculated. With this, when the medicine which has been short in delivery number at a stage preceding loading of the medicine into the selected feeder  46  in Step  3 - 3  is confirmed to have been delivered after the selected feeder  46  starts to be activated in Step  3 - 4 , the control flow proceeds from Step  3 - 6  to Step  3 - 7 . 
     In contrast, in a case where the medicine delivery has not yet been confirmed in Step  3 - 6 , the control flow proceeds to Step  3 - 10 . In Step  3 - 10 , the reason why the medicine delivery has not yet been completed is confirmed to be caused by the medicine delivery being carried out or the medicine shortage having reoccurred in the selected feeder  46 . Specifically, as in the cases of Step  1 - 9  and Step  2 - 10  described above, when the state in which the medicines are not detected by the medicine discharge sensors  46   a  continues over a predetermined time period in spite of incompletion of discharge of the medicines corresponding to one dose, it is judged that the medicine shortage has occurred. Here, when it is judged that the medicine delivery has not yet been completed owing to the medicine shortage in the selected feeder  46 , the control flow proceeds to Step  2 - 2  described above. Meanwhile, when it is judged that the medicine delivery is being carried out in the selected feeder  46 , the control flow is returned to Step  3 - 4 . 
     When it is confirmed that medicine delivery has been completed in Step  3 - 6  as described above, the control flow proceeds to Step  3 - 7 . Then, in addition to the information pieces such as the patient&#39;s name and the dose timing of the medicines, there are printed information pieces such as a name and the production-history information piece MC of the medicine (post-delivered medicine) delivered after loading of the medicine into the selected feeder  46  (refer to  FIG. 11 ). After that, when the control flow proceeds to Step  3 - 8 , the medicines (pre-delivered medicines) that have been delivered before loading of the medicine into the selected feeder  46  are packed with the packaging sheet P (packaging bag V) that has undergone printing in Step  3 - 1 . Further, when packing of the medicines in Step  3 - 8  is completed, the control flow proceeds to Step  3 - 9 , and the medicine (post-delivered medicine) delivered after replenishment of the medicine into the empty selected feeder  46  is packed with the packaging sheet P (packaging bag V) that has undergone printing in Step  3 - 7 . With this, such a state is reached that the medicine delivered from the selected feeder  46  and the medicine delivered from the alternative feeder  46  are respectively packed in the separate packaging sheets P (packaging bags V). That is, the medicines that have been commanded to be packed as one unit in prescription data enter such a state as to be packed with different packaging bags V based on the production-history information pieces MC thereof. 
     As described above, in the medicine packing apparatus  10  in this embodiment, the control means  100  is capable of specifying the production-history information pieces MC based on the production histories of the medicines delivered from the medicine feeders  46 . Thus, when medicines having different production-history information pieces MC while being of the same type are delivered from the medicine feeders  46 , medicines corresponding to one dose are separately packed based on the different production-history information pieces MC. Specifically, in the above-mentioned medicine packing apparatus  10 , in a case where medicines to be packed as one dose, specifically, medicines, which are normally collectively packed in one pack so as to be collectively taken at one time, include a plurality of medicines of the same type, when the plurality of medicines of the same type are collectively packed, medicines having different production-history information pieces MC are mixed with each other. Thus, the plurality of medicines of the same type are packed based on the different production-history information pieces MC. Further, in the medicine packing apparatus  10 , the production-history information pieces MC of the medicines specified by the control means  100  are printed on the packaging sheets P (packaging bags V) by the printing means. Thus, in the medicine packing apparatus  10 , even when medicines having different production-history information pieces MC are delivered for packing, with reference to the production-history information pieces MC printed on the packaging bags V, correspondences between the medicines and the production-history information pieces MC can be easily and accurately understood. 
     Further, in the medicine packing apparatus  10  in this embodiment, after medicines have been charged into the divisions  52   a  of the division formation body  52 , information pieces of the medicines that have been actually charged into the divisions  52   a  are printed on the packaging sheet P. Thus, in the medicine packing apparatus  10 , the packaging sheet P undergoes printing on a premise that a medicine to be packed has been charged in the division X, and hence whether or not the medicine to be packed has been correctly charged can be easily monitored. Further, in the medicine packing apparatus  10 , printing is not performed on the packaging sheet P when a failure of medicine supply occurs with respect to the divisions  52   a  constituting the division formation body  52 . Thus, the packaging sheet P and the like are prevented from being wasted when the failure of medicine supply occurs. 
     In the above-mentioned embodiment, although the production lot numbers of the medicines are used as the production-history information pieces MC, the present invention is not limited thereto. For example, production dates and use-by dates can be employed as the production-history information pieces MC. Further, the production-history information pieces MC may be obtained by composite combination of information pieces such as the production lot numbers, the production dates, and the use-by dates. Further, the production-history information pieces MC are not limited to textual information pieces, and may include barcodes. 
     Although only the medicines A are packed in the example illustrated in  FIG. 11  described in this embodiment, the present invention is not limited thereto. For example, as in the examples illustrated in  FIGS. 13 and 14 , medicines of other types (medicines B in the illustrated examples) may be packed together. In this case, as illustrated in  FIGS. 13 and 14 , the medicines A whose shortage has not occurred and the medicines B (pre-delivered medicines) that have been delivered before occurrence of shortage are collectively packed into the packaging bag V 1 , and the medicines (post-delivered medicines) that have been delivered after occurrence of shortage are packed into the packaging bag V 2 . With this, the medicines A and B can be packed so that correspondences between the medicines and the production-history information pieces MC are clarified. 
     Further, as described above, when the medicines to be packed as one dose are classified based on the production-history information pieces MC and separately packed into two or more packs (small lots), it is desired that, as illustrated in  FIG. 15 , printing be performed on the packaging sheet V so that the number of the small lots is clarified. Specifically, when medicines to be packed as one dose are separately packed into two small lots (two packs), it is desired that, as illustrated in  FIG. 15 , printing of, for example, 1/2 and 2/2 be performed on respective packaging bags V so that an awareness is promoted that the medicines corresponding to one dose are packed separately into a plurality of packaging bags V. When such printing is performed in advance, it can be instantly understood that the medicines to be collectively taken at one time are packed separately into a plurality of packs (small lots). As a result, convenience can be further enhanced.
