Description

[Detailed description of the invention] (a) Industrial application field The present invention provides a control device for a drug packaging machine that can selectively package one or several types of drugs based on different prescriptions for each patient in hospitals and the like. Regarding.

(b) Prior art A drug packaging machine inputs the drug type and number of drugs in advance using a key, as disclosed in, for example, Japanese Patent Publication No. 56-48362 and Japanese Patent Application Laid-open No. 54-38887. This is a configuration that continuously creates sachets based on Therefore, the control device of a drug packaging machine is also applied to drug inventory management in order to input the drug type and number of drugs based on the prescription, but there is still no tablet packaging machine with such a function. . However, drug packaging machines that selectively package many types of drugs currently only package tablets and cannot package liquids, powders, etc. Therefore, hospital pharmacy operators are forced to use packaging machines sent from each clinical department. Packaging is performed by selecting and inputting only the drugs that can be packaged into a drug packaging machine from a prescription. Therefore, with conventional drug packaging machines, it is not possible to input all drug types that are instructed to be taken in a prescription, and it is currently impossible to manage the inventory of all drugs at a pharmacy.

(c) Purpose of the Invention The present invention provides a control device for a drug packaging machine that can manage the inventory of all drug types in a pharmacy, including those that cannot be packaged separately by a drug packaging machine.

(d) Structure of the Invention The present invention stores the input drug type and the number of drugs as prescription data, and when input for each drug type specifies that packaging is not required, this drug type in the prescription data is stored. Correct the number of drugs to "0" and create control data, control the packaging machine based on the control data, and accumulate and store the number of drugs for each drug type stored in the prescription data upon completion of packaging. It is the composition.

(E) Embodiments of the invention FIG. 1 shows an external view of a tablet packaging machine, in which the operating device 1

FIG. 2 shows the configuration of the packaging machine 11, in which a tablet case storage section 11 is formed in the upper part, and a hopper 2, a shutter 3, and a tablet packaging mechanism 4 are provided below.
is located. Tablet cases 5...5 are placed in the tablet case storage section 1 according to the type of tablet, and the tablet cases 5...5 are driven by the input of a predetermined extraction signal to extract the tablet.
It is configured to be introduced into the hopper 2 through a falling passage (not shown). The tablet packaging mechanism 4 includes a roller 7 wound with wrapping paper 6 that can be thermally welded and folded in half in advance, a tension roller 8, and a vertical roller that vertically heat-seals the wrapping paper 6 to form a continuous pouch. It consists of a heat sealing mechanism 9, a lateral heat sealing mechanism 10 that seals the upper opening of the pouch into which tablets are placed, and a feed roller 11. Then, the feed roller 11 is driven intermittently to convey the wrapping paper 6, and when the conveyance is stopped, the packaging bag is formed by vertical heat sealing, the tablets are inserted into the packaging bag by opening the shutter 3, and the packaging paper is packaged by horizontal heat sealing. Each operation of sealing the bag is performed.

FIG. 3 shows a control device for a tablet packaging machine according to the present invention, where 13 is a control device on the operating device 10 side, and 14 is a control device on the packaging machine 11 side, which converts transmitted data into serial data and converts received data into parallel data. They are connected by a transmission line 17 via interfaces 15 and 16. The control device 13 includes a central processing unit 18 , a system memory 19 in which control procedures for the operating device 10 are programmed, a keyboard interface 20 that detects operations on the key input section 12 and generates key input signals, and a CRT 22 . It is equipped with a controller 21 that performs display control, drug file memories M ₁₁ to _{M 1o} and prescription data memories M ₂₁ to M _2o corresponding to each drug type, a control data memory M ₃ , and registers R ₃ and R ₄ . ing. The control device 14 includes a system memory 25 in which control procedures for the packaging machine 11 are programmed, a packaging machine controller 28 that controls the packaging operation of the packaging machine 11, a central processing unit 24, a memory _M4 , and a control counter 27. and,
It is equipped with registers R ₁ and R ₂ .

FIG. 4 shows that the control device 13
This is a flowchart showing the operation when registering the name/abbreviation code and code number of all drugs handled at a pharmacy in _M11 to _M1o . will be started. In this registration operation, if the drug type to be registered is a liquid medicine, a powder medicine, or even a tablet, if it is not stored in the tablet case 5...5, the packaging machine 11 cannot pack it, so the code number is not entered. This is to operate a function key that indicates not to set. Therefore, if there is a key input in the key input section 12 at step _N0 , then at step _N1 ,
It is determined whether the key input content is numerical data indicating a set code number by operating the ten keys, or indicating that the code number is not required by operating the function keys. For numerical data, N ₂
In this step, the code number indicated by this value is stored in the drug file memories _M11 to _M1o . The drug file memories M ₁₁ to _{M 1o} corresponding to each drug type are the fifth
As shown in the figure, it has a storage area of m ₇ , m ₈ , m ₉ , and m ₁₀ , and the code number data for each drug is stored in the storage area.
Store in _m7 . On the other hand, if a function key indicating that a code number is not set is operated instead of inputting a code number by operating the numeric keypad, steps _N1 to _N3 occur. When the abbreviation for the drug type is entered in step _N3 , it is determined in step _N4 whether this abbreviation overlaps with the abbreviation of another drug that has already been registered, and if there is no overlap, the _abbreviation is In this step, the abbreviation code is stored in the storage area _m8 of the corresponding storage unit _M11 to _M1o . For example, if "A" is entered as the abbreviation for a drug named "A tablet," the character code representing the letter "A" is stored in the storage area.
Stored in _m8 . On the other hand, if there are duplicates,
The code changes from step _N4 to step _N3 and waits for the code to be keyed in again. When the drug name of the drug type is key-input in step _N6 , each character constituting the drug name is stored in the storage area _m9 in step _N7 using a character code. This process is repeated for each drug type to store code number data in drug file memories _M11 to _M1o .
The abbreviation code and drug name are registered, and when it is detected in step _N8 that the function key indicating the end of registration in the key input unit 12 has been operated, the registration operation is ended.

The control device 14 performs packaging control based on control data transmitted from the control device 13, but the control device 1
The transfer mode between 3 and 14 starts when the control device 14 transmits a transfer request signal to the control device 13.
At this time, the control device 14 periodically outputs this transfer request signal without performing packaging control. FIG. 6 is a flowchart showing the normal operation of the control device ₁₃ .
Processing based on this flowchart is always executed except for registration to _M1o . In the _N10 step, "1" is stored in the register _R3 and the transfer number is set to 1, and "0" is stored in the register _R4.In the _N11 step, the transfer request signal from the control device 14 is stored. The presence or absence is determined, and if the transfer request signal is not output, the presence or absence of key input is determined in step _N12 . When the key input section 12 is operated,
Once the abbreviations and number of drugs to be administered at noon, evening, and before bedtime, as well as the number of days to take them, are entered using the keypad, in step _N13 , the prescription data based on the contents of the keystrokes is entered in the format shown in Figure 7. Create and store in any prescription data memory _M21 to _M2o ,
Hereinafter, it is assumed that the prescription data is stored in the prescription data memory _M21 .

FIG. 8 is a flowchart explaining the operation at step _N13 . When _the abbreviation of a drug is keyed in at step _n0 , the drug file memories _M11 to _M1o are checked at step n1 to determine which drug has been keyed in, and step _n2 is reached. However, if the same abbreviation as the keyed-in abbreviation is not stored in any of the drug file memories _M11 to _M1o , the process returns to step _n0 and waits for the abbreviation to be input again. The _n2 step reads the code number and drug name of the drug that match the key-input abbreviation from the drug file memories _M11 to _M1o , and stores them in storage areas _m5 and _m6 of the prescription data memory _M21 , respectively. .
However, if the entered drug type is a liquid medicine or powder medicine, or a type of tablet that is not stored in the tablet case 5...5 and cannot be packed, the key input section 12 Unnecessary keys are operated. Therefore, when the sachet-free key is operated, "0" is written in the storage area _m5 of the prescription data memory _M21 from step _n3 to step _n4 .
Then, in step _n5 , when the number of drugs in the morning, afternoon, evening, and before bedtime is input, in step _n6 , each address from 0 to 3 in the storage area _m2 of the prescription data memory _M21 is entered in the morning, afternoon, evening, and before bedtime. - When data on the number of drugs for lunch, evening, and before bedtime is written, and there is a key input at step _n7 , it is determined at step _n8 whether the content of the key input is an abbreviation related to the drug or the number of days to take it. When multiple types of tablets are packaged in one sachet, the abbreviation is input again, so the process returns to the _n1 step and the same process is repeated, and the prescription data memory _M21 stores data that matches this abbreviation. The code number, drug name, and number of drugs to be used are stored. When the setting of the medicines to be packed in one sachet and the number of medicines is completed, and the number of days to be taken is entered in step _n7 , steps _n8 to _n9 are entered in the prescription data memory _M21 . Store the number of days data in storage area _m1 . n ₁₀ steps calculate the total number of sachets for each morning, noon, evening, and before bedtime by inputting the number of days data, and store it in the prescription data memory.
Store in each address 0 to 3 of storage area _m3 of _M21 . In step _n11 , the transfer number stored in register _R3 is written to storage area _m4 of prescription data memory _M21 , and in step _n12 , the contents of register _R3 are incremented by 1 and the transfer number is advanced by one. teN ₁₁
Move to step. If the prescription data key is input again while the transfer request signal has not been sent, the prescription data is stored in the memory M ₂₂ , but at this time, the storage area of the prescription data memory M ₂₂ is
Since the contents of register _R3 have been incremented by 1, the transfer number advanced by one is stored in _m4 .

Figure 9 shows the CRT22 at the time of such key input.
It shows the display contents, including the drug name specified by the operator's key input and the morning date of this drug. noon·
The number of medicines taken in the evening and before going to bed and the number of days are displayed on display parts 31, 32,
33, and the code numbers read from the drug file memories _M11 to _M1o based on the abbreviations are displayed on the display section 34. In the input example shown in Figure 9, one tablet A, one B, and one C are packed in the morning, noon, and evening for 7 days, and one powder E is packed in the morning, noon, evening, and before bedtime. This indicates that a key input has been made to package each unit for 7 days. In addition, the powder medicine E powder is
The packaging machine 11 cannot package the packaged medicines, so they are packaged manually or by other powder medicine packaging machines, but they are input for inventory management. Therefore, code number data for each drug A, B, C, and E is written in each storage area _m5 from No. 1 to No. 4 of the prescription data memory M ₂₁ , and from No. 1 to No. Medication number data "1" is written in addresses 0 to 2 corresponding to morning, noon, evening, and before bedtime in each storage area _m2 that stores drug number data up to No. 3, and address 3 is written with drug number data "1". "0"
is written, and each address 0 of storage area _m2 of No. 4
3 are respectively written with "1", and the number of days data "7" is written in the storage area _m1 . Then, by inputting the number of medicines data and the number of days data, the total number of sachets for each morning, noon, evening, and before bedtime is calculated and stored in each address 0 to 3 of the storage area _M3 .
It is displayed on the display section 35 of No. 2. Furthermore, since Powder E cannot be packaged using the packaging machine 11, the code number "0" is stored in the prescription data memory M ₂₁ , but the display section 34 of the CRT 22 displays "..." for Powder E. This indicates that it cannot be packaged.

After creating the prescription data in this way, the program returns to the _N11 step, and when it detects that a transfer request signal is being sent from the control device 14, the _N14 step is reached and the contents of the register _R4 are other than "0". Determine whether the value is . When the packaging machine 11 is in a packaging operation, the register _R4 stores the transfer number of the prescription data that is the basis of the packaging operation at this time. Therefore, currently, when the packaging machine 11 has stopped its wrapping operation, the contents of register _R4 are "0", so _N10
The process moves to step and determines the presence or absence of prescription data. Then, when the prescription data is stored in the prescription data memory M ₂₁ through the process of the N ₁₃ step described above, the prescription data is stored in the prescription data memory M ₂ at the N ₂₀ step.
The transfer number stored in the storage area _m4 of is written to the register _R4 , and the controller ₁₄
The prescription data to be transferred to the computer is converted into control data according to the format shown in FIG. Incidentally, if prescription data is stored in any two or more of the prescription data memories _M21 to _M2o , the prescription data stored in the storage area _m4 with the smallest transfer number is selected.

FIG. 10 shows a flowchart for creating control data, in which the _m20 step selects the memories _M21 to _M2o that store prescription data, and selects each memory area _m5.m of the selected memory _M21 . ₂ specifies the first storage area m ₅ /m ₂ . The _n21 step transfers the drug code number data stored in the storage area _m5 of the prescription data memory _M21 to the control data memory _M3.
write to the storage area m ₅ ′. Control data memory _M3
is the storage area _m2 of the prescription data memory _M21 to _M2o .
It has storage areas m ₂ ′, m ₃ ′, and m ₅ ′ corresponding to m ₃ and m ₅ . The _n22 step determines whether the code number data stored in the storage area _m5 ' is "0",
If it is other than "0", it becomes _n23 steps and each address 0 to ₂ of storage area m2 of prescription data memory _M21 is processed.
The data on the number of medicines for each morning, noon, evening, and before bedtime stored in M3 are stored in each address 0 to 3 of the storage area _{m2 '} of the control data memory M3. In the case of "0", "0" is written in each address 0 to 3 of the storage area _{m2 '} of the control data memory M3 in step _n24 . The _n25 step shifts the storage areas _m5 and _m2 of the prescription data memory _M21 , respectively, and the _n26 step determines whether all the storage areas _m5 of the prescription data memory _M21 have been designated. Takes n ₂₁ steps to n ₂₆
By repeating the process up to step _n20 , the storage area _m5 of the prescription data memory _M21 selected in step n20 is
The code number data of the drug stored in is transferred to the control data memory _M3 , and if the code number data is other than "0", the data of the number of drugs of the drug type is written as is to the control data memory _M3 , If it is "0", the drug number data of the drug type is corrected to "0" and written into the control data memory _M3 .
Therefore, in the input example shown in FIG. 9, the storage areas m ₅ ' from No. 1 to No. 3 of the control data memory M ₃ contain code number data for each tablet A, B, and C, and No. 4. ``0'' is written in the storage area m ₅ ' corresponding to the E powder, and data from No. 1 of the control data memory M ₃ is written.
“1” is written to addresses 0 to 2 of each storage area m ₂ ′ up to No. 3, “0” is written to address 3, and 0 to 3 of storage area m ₂ ′ of No. 4 is written. "0" is written to each address.

The _n27 step specifies the first address 0 in the storage area _m3 of the storage section of the prescription data memory _M21 selected in the _n20 step, and also specifies the address 0 of each storage area _{m2 '} of the control data memory M3. 0
Specify each. The _n28 step determines whether the logical sum of the drug number data for each drug type stored at address 0 of each storage area m ₂ ' is "0". At this time, if at least one of the drug count data stored at address 0 of each storage area m ₂ ' is other than "0", the data stored at address 0 of storage area m ₃ at step n ₂₉ is The total number of sachets data is
Address 0 of storage area m ₃ ' of control data memory M ₃
write to. Also, if the drug number data stored at address 0 of each storage area m ₂ ' is all "0",
Control data memory _M3 storage area with n ₃₀ steps
Write "0" to address 0 of m ₃ '. The _n31 step stores the prescription data memory _M2 selected in the _n27 step.
Shifts the address in the storage area _m3 of the storage unit from 0 to 1, and also shifts the address in the control data memory
The addresses of each storage area m ₂ ' of M ₃ are all shifted from 0 to 1, and the n ₃₂ step determines whether the address of the storage area m ₃ of prescription data memory M ₂ has exceeded, and the address is within 3. We are moving to _n28 step. In the processing from step _n28 to step _n32 , the logical sum of the drug number data for each drug type stored in each address 1 of each storage area _m2 ' of the control data memory _M3 is "0". It is determined whether or not it is necessary to correct the daytime total number of packets data, and if it is other than "0", it is assumed that no correction is necessary and the data stored at address 1 of the storage area m ₃ is transferred to the storage area m ₃ ′. Write to address 1 of , and if it is "0", the storage area
Write "0" to address 1 of m ₃ ' to correct the data on the total number of packages. Similarly, the total number of sachets for the evening and before going to bed is determined to be corrected by the processing from step _n28 to step _n32 , respectively, and is stored in addresses 2 and ₃ of storage area _m3 ' of control data memory M3. Predetermined data is written respectively. When the address of the prescription data memory _M2 exceeds the storage area _m3 , the step changes from _n32 steps to _N22 steps. Therefore, according to the prescription input in this example, the dose before bedtime is E.
Since the logical sum of the data stored at address 3 of each storage area m ₂ ' in the control data memory M ₃ is "0", the storage area
The corrected value "0" is written to address 3 of m ₃ '.

In the _N22 step, the total number of sachets for each morning, noon, evening, and before bedtime stored in addresses 0 to 3 of the storage area _m3 ' of the control data memory _M3 is all "0".
If it is "0", there is no need to separate packages using the packaging machine 11, and the process returns to step _N11 . However, if the total number of packages in at least one of the morning, noon, evening, and before bedtime periods is other than 0, the packaging machine 11 must be used to package the packages, and the control data is controlled in step _N23. The control data is transferred to the device 14, but at this time, the control data is serially converted by the interface 15 and transmitted. After the transfer is completed, the process returns to step _N11 , but since the control device 14 is controlling the packaging of the packaging machine 11 by receiving the control data, it does not output a transfer request signal. Therefore, the control device 13 repeatedly determines whether or not there is a key input in step _N12 , and if there is a key input, the step goes to step _N13 , and the key is stored in any prescription data memory _M21 to _{M2o that} does not store prescription data. Store input data.

The operation of the control device 14 will be explained with reference to the flowchart shown in FIG. When the transfer request signal is output and control data is received at the N ₀ ′ step, the N ₁ ′ step changes to the N ₂ ′ step, and the control data is stored in the memory.
Store in _M4 . Memory M ₄ has storage areas corresponding to each storage area m _{2 ′} , m ₃ ′, m ₅ ′ of memory M 3.
Equipped with m ₂ ″, m ₃ ″, and m ₅ ″, each has drug count data and
Stores total package number data and drug type code number data. In the N ₃ ' step, the ternary control counter 27, which repeatedly counts from "0" to "3" each time 1 is added, is set to "0".
The N ₄ ′ step determines whether the contents of the storage area m ₃ ″ of the memory M ₄ are “0”. Storage area m ₃ ″
The total number of sachets is stored in four addresses from 0 to 3 corresponding to daytime, evening, and before bedtime, but in this case, address 0 is specified because the content CN of the control counter 27 is "0". Then, it is determined whether the morning total number of sachets data is "0". In this example, the number of packets to be taken in the morning is for 7 days, and the process moves to the _N5 ' step. N ₅ ′ step is the storage area of memory M ₄
The code number data stored in m ₅ ″ is stored in register R ₁ , and the drug number data stored in storage area m ₂ ″ is stored in register R ₂ . At this time, regarding the storage area m ₂ '', since the content CN of the control counter 27 is "0", first the drug number data stored at address 0 of each storage area m ₂ '' is read out and stored in the register R ₂ . Therefore, the code number data for each tablet A, B, and C is written in register _R1 , and the data on the number of medicines for the morning packet for these tablet types is written in register _R2 . The N ₆ ′ step determines whether the contents of register R ₂ are “0” or not, but if the drug count data of at least one tablet type for each tablet type A, B, and C is other than “0”, N ₇ ' step and the tablet extraction operation. In the _N7 ' step, the code number data for the tablet types whose drug number data is other than "0" is read out from the register _R1 and introduced into the packaging machine controller 28. Then, the packaging machine controller 28 outputs an extraction signal to the tablet cases 5...5 storing various tablets A, B, and C. Therefore, the tablet cases 5 to which the extraction signal has been introduced are driven to extract one tablet. In the N ₈ ' step, "1" is subtracted from the drug number data for the tablet type for which the extraction operation was performed, and the process returns to the N ₆ ' step. In this example, the morning parcels include A, B,
A register is used to package various drugs of C, one tablet at a time.
The data for the number of various drugs A, B, and C stored in R ₂ is "0". Therefore, 1 in the morning
The divided tablets are taken out and introduced into the hopper 2, and the packaging operation is performed in the next step _N9 '.
At step _N9 ', the packaging machine controller 28 gives control signals to the shutter 3, the horizontal heat sealing mechanism 10, and the vertical heat sealing mechanism 9, respectively, to control each operation of inserting tablets, sealing sachets, and forming sachets, After that,
A control signal is applied to the drive device of the feed roller 11 to transport the wrapping paper 6 by a predetermined length in the longitudinal direction, thereby completing the wrapping operation of the morning dose packet. In the N ₁₀ ′ step, address 0 of the storage area m ₃ ″ of the memory M ₄ is specified by the content “0” of the control counter 27, and “ ₁ ” is subtracted from the data stored there. In the step, it is determined whether the data at all addresses 0 to 3 in the storage area m ₃ '' are "0". In this case, one packet for the morning dose is completed and the storage area is
This is the stage where "1" has been subtracted from the data at address 0 of m ₃ ", and the content CN of the control counter 27 is advanced from "0" to "1" at step N ₁₂ ', and the process returns to step N ₄ '. Then, in the N ₄ ' step, since the content of the control counter 27 is "1", address 1 of m ₃ " is specified and it is determined whether the content is "0". At this time, the content of address 1 is "7". "for
The program moves to the _N5 ' step and begins the packaging operation for daytime meals.

In the N ₅ ′ step, the code number data stored in the storage area m ₅ ″ is stored in register R ₁ , and
The medicine number data stored at address 1 of each storage area m ₂ ″ is stored in register R _2. Then
When going from the N ₆ ′ step to the N ₇ ′ step, tablet cases 5...5 for tablet types whose drug number data stored in register R ₂ are other than "0"
Remove the tablet from the N ₈ ′ step and register R ₂
Subtract "1" from the drug count data. In this example,
In the daytime packets, each drug A, B, and C is packed one tablet at a time, so the data on the number of drugs in register _R2 is all "0" and the steps are from _N6 ' step to _N9 '. In the _N9 ' step, the one daytime packet of tablets taken out into the hopper 2 is wrapped.
In the _N10 ' step, "1" is subtracted from the data stored at address 1 of the storage area _m3 " to store that the daytime one-pack operation has been completed. and
When the step changes from the N ₁₁ ' step to the N ₁₂ ' step, the content CN of the control counter 27 is advanced from "1" to "2". Therefore, from the next N ₄ ′ step, since the content of the control counter 27 is “2”, the storage area m ₅ ″・
m ₂ '' is specified by address 2, and processing is performed for the evening sachet operation. After that, when the evening sachet operation is completed, the contents of the control counter 27 are
Advance CN from "2" to "3" and return to the N ₄ ' step. At this time, the content of address 3 of the storage area m ₃ '' is "0", and the step is from N ₄ ' to N ₁₁ '. That is, in the input prescription of this example, since the E-powder which cannot be packaged by the packaging machine 11 before going to bed is packaged, the packaging operation for the dose taken before going to bed is omitted. Then, in step _N12 ', the content of the control counter 27 is advanced from "3" to "0",
Processing for morning parcels is performed again. In this way, addresses 0 to 3 of storage area m ₃ ' of memory M ₄
The packaging operation is repeated in the order of morning, noon, and evening until all the data stored in is 0. When the packaging of 7-packs for 7 days in the morning, afternoon, and evening is completed, it is assumed that the packaging for one input prescription has been completed, and the process returns from the N ₁₁ ' step to the N ₀ ' step.
Then, in step N ₀ ', a signal requesting transfer of prescription data regarding the next packaging operation is transmitted to the control device 13.

When the control device 13 detects in step _N11 that the control device 14 is outputting a transfer request signal, it transfers the prescription data to the control device 14 and stores the transfer number in register _R4 . Because of this, the number of steps is _N15 instead of _N14 .
The _N15 step selects the drug file memory corresponding to the drug name stored in the prescription data memory _M21 .
_M11 to _M1o are indexed, and the cumulative number of medicines is recorded in the medicine number storage area _m10 of the memory in step _N16 . _N17
In step clear prescription data memory _M21 ,
At the _N18 step, set register _R4 to ``0'' and set _N19.
It becomes a step. In this way, the control device 13 determines whether or not there is a transfer request signal at step _N11 to indicate that the packaging operation based on the transferred control data has been completed.
Judging from the contents of register _R4 in step _N14 , the drug file memories _M11 to _M1o corresponding to the drug type indicated in the packaged prescription data are specified and stored in the storage area _m10 . The data on the number of drugs for the relevant drug type is added to the cumulative number of drugs in the list. and any prescription data memory _M22 to _M2o
If the prescription data is stored in , control data is created again, and in the case of a drug type that can be packaged by the packaging machine 11 , this control data is transferred to the control device 14 . The data stored in the drug file memories M ₁₁ to M _1o can be transferred to the CRT by inputting a display command to the central processing unit 18 by operating a predetermined key on the key input section 12 to instruct the display of such data.
22. That is, in the flowchart of FIG. 6, it is determined in step N24 that the display command has been generated in a state where no transfer request signal has been transmitted from the control device 14 and no prescription input has been made to the key input section ₁₂ . When detected, the data stored in the drug file memories _M11 to _M1o is introduced into the CRT controller 21 at step _N25 .
The CRT22 displays the code number, abbreviation code, drug name, and cumulative number of drugs for each drug type.

(F) Effects of the Invention According to the present invention, when the drug type and the number of drugs are input, this is stored as prescription data, and when the input drug type specifies that separate packaging is not required, the drug is Control is performed so that the number of seeds is corrected to "0" and the packaging operation is performed. Therefore, it becomes possible to input all types of drugs handled at a pharmacy, including drugs that cannot be packaged by a packaging machine, according to prescriptions, and a drug packaging machine with drug management functions is provided. Furthermore, in order to specify whether or not packaging is required for each drug type, it is not only possible to determine whether or not the drug is stored in the packaging machine, but also to set the stored drug types to be unpacked as appropriate, resulting in the effects described below. There is. That is, the drug packaging machine is configured so that if the drug specified for packaging cannot be extracted normally due to a malfunction in the tablet case, the machine stops operating as an abnormality. However, if recovery requires time, it is customary for pharmacies to manually package the drug types that will not be extracted, and use a packaging machine to package other drug types that can be successfully extracted. Therefore, in such a case, if a drug type that is not extracted is entered, the packaging machine will not operate and the input will not be possible, which will cause problems in drug inventory management.
However, according to the present invention, it is possible to input the types of medicines that are not extracted normally, so that the cumulative number of medicines can be accurately recorded.
