In step 344, the selected compound number, designated compound compound weighing frequency, input position, and weigh m value of the routine executed in steps S34 to S43 are stored in the output memory of the printer 30.

In step 845, the setting value "(J") of the combination drug type memory that determines the combination drug selection order address is updated to "U-1", and the value of the combination drug type memory of the combination drug on the card is changed to the next one. The combination drug information address to be selected is set in the address memory. Then, in step S46, it is determined whether the designated combination drug type number r Ll , 1 in the combination drug type memory is rOJ, and the designated combination drug in the combination drug type memory is set. From step 834 to step S46 until the number of types rUJ becomes rOJ.
A predetermined type of compounding agent is selected and weighed through a routine process. If it is determined in step S46 that the specified number of compounded drug types rUJ in the compounded drug type memory is rOJ, this means that the selection of compounded drugs for one bag has been completed.
In step S47, the total weight of the rUJ type compounding agents is calculated. Then, in step 848, it is determined whether the calculated value is within a predetermined total tolerance value, and if it is not within a predetermined total tolerance value, step 349
The system abnormality indicator light 16 is turned on in step S50, and the processing of this main program is stopped in step S50. At this time, the task is to discard the previously weighed compound.

If the calculated value in step S48 is within the predetermined tolerance value of 1 - 1 tal, it means that the selection and weighing of the compounded ingredients for one batch has been completed as specified, so in step 851 the batch number yen memory is stored. Set settings l! "N", l
Update as N-1J.

In step 852, it is determined whether the set value rNJ set in the batch memory is "0", and if the set value rNJ set in the batch number yen memory is not "0", the set value of the batch number setter 27 is determined. This means that processing of the number of batches specified by rNJ has not been completed, so step 85
3, the blue patrol light 36 and one batch end indicator light 13 are turned on, and the buzzer 32 is emitted three times at 0.5 second intervals to instruct the end of one batch.

Then, in step 854, the data stored in step 844 and the total compound weight data for one batch calculated in step 847 are printed out. When the input switch 29 is turned on again in step S55 and it is determined that the next batch of premature ejaculation has been completed, step S2
The routine processing from step 3 to step 852 is executed.

If it is determined in step S52 that the set value rNJ set in the batch number yen memory is rOJ, step 85
At 6, blue light 36 and all batch completion indicator light 12
is turned on, and the buzzer 32 is sounded three times at one-second intervals to indicate completion of all batches. When it is detected in step 357 that the card has been removed from the card reader 25, the timer is activated for 1 second in step 858, and the processing of this main program is started 1 second after the card is removed from the card reader 25.
