In an actual case, a pharmacist, that is, the operator needs to know the corresponding relationship between each shelf number and the corresponding medicine, and this imposes serious loads on the operator. Moreover, the operation of the maintenance screen is plicated, and tends to cause input mistakes, with the result that it is difficult for the pharmacist to operate it during a medicine packing process. Further, it is also difficult for the pharmacist to confirm the operations of attaching and detaching a medicine container to and from the corresponding shelf section. For this reason, there has been a demand for a system for detecting the presence or absence of a medicine container on a shelf section and for displaying the shelf section to which a medicine is attached or the shelf section from which a medicine is detached.In particular, in the case of a smallsize medicine packing apparatus, since there are few shelf sections of medicine supplying shelves and since the medicine containers are small, the exchange of medicine containers is frequently carried out, causing a higher probability of attaching mistakes of medicine containers to the shelf sections.SUMMARY OF THE INVENTIONAccordingly, an object of the present invention is to provide a medicine packing apparatus which makes it possible to carry out the operations of attaching, detaching and exchanging medicine containers during a medicine packing operation.In order to achieve the abovementioned object, a medicine packing apparatus of the present invention, in which medicine containers housing medicines are classified into respective kinds and are attached to a plurality of shelf sections so as to supply and pack the corresponding medicine from the corresponding medicine container of the shelf section, includes: a storing unit for storing shelf numbers of the respective shelf sections and the respective kinds of medicines housed in the medicine containers。 and a control unit for allowing the storage unit to store the corresponding relationship between the kind of a medicine housed in the medicine container and the shelf number upon attaching the medicine container to the shelf sections, and for erasing the corresponding relationship from the storage unit upon detaching the medicine container from the shelf.With this arrangement, by only attaching and detaching medicine containers to and from the respective shelf sections, the shelf numbers and the corresponding kinds of medicines are shown in parallel with each other. Therefore, it bees possible to carry out the operations of attaching, detaching and exchanging medicine containers during a medicine packing operation. For this reason, even when the kinds of medicines bee more than the number of the shelf sections, it is possible to deal with such cases by exchanging the medicine containers during a packing process.Moreover, when a display unit which displays the corresponding relationship between the shelf number of the shelf section to which the medicine container is attached and the medicine placed therein or the corresponding relationship between the shelf number of the shelf section from which the medicine container is detached and the medicine detached therefrom, is added to this apparatus, it bees possible to confirm the operations of attaching and detaching the medicine containers to and from the respective shelf section, and this arrangement makes it possible to prevent the operator from being confused even when the number of attaching and detaching operations increases.In this arrangement, when the display unit is allowed to display shelf numbers of the shelf sections to which medicine containers containing medicines included in prescription data are attached and shelf numbers of the shelf sections to which t
