Further, the power supply P29 is connected to the CPU4 through a resistor 40.
A normally open program selection switch 41 for specifying switching to the check state is connected between the ground and the ground.

In addition, 42 is a check cable, and this check cable 42 is connected to the output terminal 27 and the input terminal 28 after removing the signal cable 3 to short-circuit them.

In such a configuration, the label printer 1 and the scale 2 are connected as shown in FIGS. 1 and 4, the program selection switch 41 is OFF, and the unit price deletion switch 1 is OFF.
2, the weight erase switch 13, the price erase switch 14, the processing date erase switch 15, and the effective date erase switch 16 are all OFF, and the select button 9 is set to automatic.

Then, the unit price setting key 20 is pressed to set a unit price of, for example, 100 yen per 100 f, and the product is placed on the weighing pan 2a and its weight is measured.

If this weight is 1231, it is displayed on the weight display section 1B, and the price is calculated and the price display section 1
9 is displayed as 123 yen.

At the same time, this price data is transmitted to the label printer 1 via the signal cable 3, and given to the CPU 4, where a label 5 printed as shown in FIG. 6 is issued.

Such an operation is performed in the same way every time the product is weighed, and a label 5 with different printed content depending on the weight is formed and attached to the product.

In order to issue the label 5 in this way, data must be sent and received between the label printer 1 and the scale 2, but both have a photocoupler 31 on the input side.
37 is provided, and there is no need to provide a voltage level conversion circuit or the like.

Note that when the select button 9 is set to manual, the label 5 is issued by pressing the issue key 10.

The label printer 1 performs various operations such as printing, label feeding, erasing prints, selecting the printing format, and other operations, but when checking these operations, the signal cable 3 must be removed and the Connect the check cable 42 as shown in Figure 5.

Then, the program selection switch 41 is turned on.

As a result, the CPU 4 switches to a check program and executes the task.

This process will be explained according to the flowchart shown in FIG.

First, a check signal is output from the CPU 4 to the output terminal 27, passes through the check cable 42, and returns to the CPU 4 from the input terminal 28 to issue an operation instruction.

When a start signal for checking is issued from the CPU 4, the counter is first cleared.

This counter is used to set the printing contents, and since there is no unit price, weight, and price data at the time of checking, the contents of the counter are replaced with those data and printed on each part.

After this counter is cleared and becomes 0, signals from various switches such as the unit price erase switch 12 and date data are taken in, and then it is determined whether the program selection switch 41 is ON or not. A check is made.

When this is OFF, the above-mentioned main program proceeds, and when it is ON, after checking whether the issue key 10 has been pressed, it is checked whether the select button 9 is set to automatic.

If this is automatic, the contents of the counter will be changed to unit price, weight,
Output as price data, set the counter to +1 as the next check data, then input the previous data O.
Store as printing data in unit price memory, weight memory, and price memory.

Next, if the unit price deletion switch 12 is OFF, the unit price is printed, and if it is ON, the process moves to the next job.

Similarly, check for weight deletion and price deletion in sequence, then feed the paper and change the print position, then check for processing date deletion and effective date deletion, then feed the paper and automatically Check whether
If it is automatic, it is checked whether the contents of the counter have reached the number of times n to be checked, and the same operation continues until the number of times n is reached.

Then, when n is reached, the counter is cleared and the check of the automatic issuance operation is completed.

Therefore, in the case of automatic issuance, the first label 5 is printed as 000... in the column that should be printed, and the second 2-bell 5 is printed as 111... On the third label 5, the same numbers are arranged so that 222... is printed.

Of course, such label 5 issuance is set as a print check state in automatic mode, and is not limited to this.

Next, if the aforementioned select button 9 is set to fixed amount issuance, the contents of the counter will be 012345, for example.
It is set to 6789.

This content is output as data, and then the counter is incremented by 1 for the next check.

+1 in this case means the content of the counter is 90123456
It is said that it will be 78.

The first data is then output and the process proceeds as in the case of automatic publication.

A second check is then performed by pressing the issue key 10.

Next, if the select button 9 is set to manual, the process proceeds in the same way as the automatic issue, but the issue key 10
Proceed sequentially by pressing .

In this way, all of the operational functions of the label printer 1 are checked.

In the present invention, as described above, the label printer and the scale are provided separately, and a photocoupler is connected to the input terminal side of each. Therefore, when transmitting and receiving data, a voltage level conversion circuit between the two is connected. In addition, since it is possible to connect a check cable that shorts the input terminal and output terminal on the label printer side, it is possible to easily check the functionality of the label printer. This has the advantage of being able to check even functions.
