At this time, the data supplied from the electronic scale 5-1 to the CPU 2 includes aggregation data including heavy handling data, amount data, processing date, best-before date, etc. of the goods weighed in the electronic scale 5-1. When a failure is detected, there is failure detection data that is created in response to the failure situation. Details of this failure detection data will be described later. After communicating data with the electronic scale 5-1, the CPU 2 moves to the command shown in FIG. ,
Execute the data processing instruction shown in a5. Here CPU2
calculates, counts, and organizes the above-mentioned data for aggregation, and stores the results in a predetermined storage area in the entire memory 7. Next, the command shown in CPU 2 digit a6 (adds 1 to digit K). In other words, in this case, performs the operation i!, 1+1=2, and for the next data communication, digit 5- 2'?i: Specified.Then, the CPU 2 returns to executing the instruction indicated by al.

By the way, during the above operation, CPU 2 is a2
If an error is detected in the response signal supplied from the electronic scale when executing the command shown in , the CPIJ2 moves to the command shown in al, and checks the content of this error? i: Display section 8° Print section 4 displays and prints, respectively. An example of the display on the display unit 8 at this time is shown in FIG. In this figure, numerals 10a to 10d are character and numeric indicators each composed of a light emitting diode. The display 1゜a is a display that displays the scale number of the scale whose communication is being checked. In this case, since the communication check of the electronic scale 5-1 is being performed, the display W10a shows "]J.
is displayed. The display 10b displays characters to distinguish whether a communication error is a failure of the scale, and in this case, the character A indicating a communication error is displayed. Display 10C
is a number indicating what caused the error that caused the display to appear on the display 10b? i: Display. This number is set according to the cause of the failure, for example, "l" for a communication failure determined from a parity check, "2" for a connector failure determined from missing data, etc. .

In this case, T "2" is displayed, indicating that the connector is defective. The display 10d displays characters indicating the treatment method corresponding to the failure displayed at 10b and 10C. For example, replace this character with "X", "
These are set to correspond to each treatment, such as "C"...Check, "S"...Call for service, etc. In this way, the display example 1'-1-A-2-8 shown in FIG.
means that the electronic scale 5-1 of the scale tSJ-1 has caused a communication error due to a faulty connector, and that a service call should be made. At this time, the same content as that displayed on the display section 8 is printed on a predetermined paper by the printing section 4. and,
