However, if the key-in abbreviation does not match any of the abbreviations stored in the search memory (B), error handling such as displaying the input error on the CRT display (G) will be performed. This is performed in the search routine and waits for the abbreviation key-in again.When a normal abbreviation key-in is performed, the CRT display (G) first displays the keyed-in abbreviation and displays the drug name on the CPU (B). Upon detection, the name of this drug is displayed.Then, when keys (valve for the tablet type in administration (that is, one-pack)) are successively keyed in, the CPTJ (b) introduces this data on the number of drugs into the prescription buffer memory α. By repeating this operation, the tablet type and number of drugs for one medication are set, and by operating the drug type specification end key on the keyboard (to), the mode is set to specify the number of doses (i.e., the number of sachets), and the CPU 04) The input of one prescription data is completed by introducing the keyed-in number of sachets into the prescription buffer memory QO.

Data is transferred to and from U (1 station, and the Kuwana code and packaging data are stored in the prescription buffer memory Q1 of the tablet packaging machine (13A)). Therefore, the processing device stores data on the number of drugs for each tablet type stored in the prescription buffer memory Q1) in the memory M1, and performs a tablet extraction operation on the condition that the memory M is not 0. After setting the extraction flag I7 in the memory M2 for each tablet type to be dispensed,
The Kuwana code is output to the packaging mechanism (2). When the tablet packaging control unit (a) receives an input signal indicating the Kuwana code, it sends a tablet case (5) containing the tablet type corresponding to that number.
) is driven to eject the tablet. Tablet case (5)
A processor is installed at the tablet dropout port at the bottom of the tablet, and the processing device (e) is in a standby state for 250m5 from the output of the Kuwana code until the detection signal from the ejected tablet is introduced by the sensor. . When a detection signal is introduced from each tablet case that outputs the Kuwana code, the processing device (I) outputs the detection signal to the memo IJM. If there are multiple tablet types, the processing device will output the Kuwana code for each tablet type sequentially in a time-sharing manner, and after 250 m5 has passed, each detection for each tablet type will occur at a predetermined timing in the order in which the code numbers are output. The signals are sequentially stored in the memory IJM3. After writing to memory M, the processing unit member then writes data to memory M2.
, M are compared to determine whether all the tablet types to be extracted have been discharged, and if they are equal, 1 is subtracted from the number of tablets for each tablet type. However, if the contents of the memories M7 and M3 do not match, the processing device outputs an abnormal signal to the CPU α, and then transfers the Kuwana code of the tablet type that was not ejected. When the data transfer with the processing device (1) of the tablet packaging machine (13A) is completed, the CPU α→ can perform key-in related to the next prescription, but performs interrupt processing by inputting an abnormal signal. In this interrupt processing, the CPUQ41 receives the abnormal drug name low y from the processing device (E) and introduces it to the interface 0 wound, and the CRT display device (G) displays this drug name and indicates that it is abnormal. Show that.

This is a diagram showing the connection between the control circuit and the processing device related to (5), where the processing device (E) has output lines N1, N2, etc.
・Nn outputs the code number in binary code, and the reset line/S and reset line R output a set signal and a reset signal, respectively. The sensor 0131 in each tablet case (5)...(5) is configured to output a detection signal to the processing device (a) through line 1 upon detection of the tablet. Also, tablet case (5)...
- The control circuit (5) includes the aforementioned switch device (b) in which the Kuwana code of the stored tablet is set in advance, the Kuwana code introduced from the processing device, and the Kuwana code set in the switch device G. It is equipped with a comparison device (1) for comparing the tablets, a memory circuit, and a drive device (1) for performing a tablet extracting operation. With this configuration, when the processing device outputs a set signal together with the Kuwana code, a matching signal is obtained from the comparison device (a) of the tablet case (5) corresponding to the Kuwana code, and the signal is sent to the data terminal of the storage circuit. The memory circuit receives a signal from the processing device (a) through the line S, so the drive device (e) starts operating. If there are a plurality of tablet types to be discharged, the Kuwana code for each tablet type is output, and at the same time, a conversion signal is output to sequentially set the memory circuit. But 250 ms
When the period has elapsed, the processing device (4) scans the detection signal on line L in a time-division manner, detects the presence or absence of tablet ejection for each tablet type for which the Kuwana code has been output at each timing, and outputs a reset signal through line R. Reset the memory circuit.

In the flowchart of FIG. 5, it is detected that the first tablet of the specified tablet type is ejected normally, and the data of the number of tablets for each tablet type stored in the memory M1 is detected. When 1 is subtracted from
JM, determine whether or not it is necessary to extract the second tablet based on the data on the number of tablets. When it is determined that it is necessary to eject the second tablet, the processing device stores the tablet type that requires ejection of the second tablet in the memory M2 again, and repeats the above operation. When the drug number data in the memory M becomes all 0, the processing device enters the packaging machine control mode, and the packaging machine controller (2) closes the shutter (3).

With the completion of this transfer, packaging of one sachet is completed.Next, the processing device (1) subtracts 1 from the sachet number data stored in the prescription buffer memory Q and stores the sachet number data. If it does not become 0, the tablet type data and the drug number data of the prescription buffer memo IJal) are stored again in the memory M, and the second packaging operation is performed. When the specified number of packages is completed and the number of packages data in the prescription buffer memo IJ@]) becomes O, the processing device resets the BSY flag and the tablet packaging machine (13A) ends its operation. Ru. This tablet packaging machine (1
During the operation of 3A), the CRT display device displays the contents of the prescription buffer memory under the control of the processing device, and when the processing device detects non-ejection of a tablet, it displays the drug name of the tablet type on the CRT display. Control the device to be displayed as a threat.

As mentioned above, when the CPUa station receives prescription data,
Select a tablet packaging machine (13 people) (13B) that accommodates the tablet type specified by this prescription data, and when the selected packaging machine is in a non-operating state, the Kuwana code and number of drugs related to that packaging machine are displayed. This is to send packaging data of the number of packages. If the tablet type specified by the prescription data is spread across multiple tablet packaging machines, the corresponding packaging data will be sent in sequence on the condition that all the selected packaging machines are inactive. . Therefore, each selected packaging machine performs the packaging operation in parallel, so that even if packaging for prescriptions is performed by different packaging machines, the packaging is done at the same time.

(f) Effects of the Invention According to the present invention, the controller selects a tablet packaging machine storing the tablet type according to the prescription data by inputting prescription data, and transmits packaging data based on this prescription data. - A plurality of tablet packaging machines can be operated simultaneously regarding prescriptions, and selective packaging of many types of tablets can be efficiently accomplished. Moreover, since a plurality of tablet packaging machines are controlled by one controller, it does not take up space in the pharmacy, and moreover, it has the advantage that it can be operated by a human operator.
