Summary of the Invention The present invention is configured to issue an inspection label on which all of the setting data is printed when setting various data in each PLU memory, thereby confirming the setting contents using the inspection label. You can also use the inspection label to create a list of settings.
The configuration is such that the correction is easy.

Embodiment of the invention First, in FIG. 1, the CPU 11 includes a weighing section 2,
While mode selector switch 3 is connected
Connected are a program memory 4 consisting of ROM and RAM, a PLU memory 5 consisting of RAM, a display/key device 6 equipped with keys as a setting means for setting various data, and a CPU 27 that controls the printer. This CPU27 has
A program memory 8 consisting of ROM and RAM, a character generator 9 consisting of ROM,
A print buffer 10 consisting of RAM is connected. The CPU 27 also includes a label detector 11 that also functions as a means for selecting whether or not to issue an inspection label, a pulse motor drive 13 that drives the pulse motor 12, a common drive 15 that controls the thermal head 14, and An image signal drive 16 is connected.

Next, the printer section 14A as a label issuing means will be explained based on FIG. First, rectangular labels 18 are attached to a long mount 17 at regular intervals. This mount 17 is wound up by a winding part (not shown) via a roller 19, a platen 20 serving as a label feeding part, a peeling plate 21, and a roller 22. A thermal head 14 is provided above the platen 20 and is connected to the label 18 for printing. Further, since the mount 17 is sharply bent at the peeling plate 21, the label 18 is peeled off and pushed out horizontally, but a label detector 11 is provided close to the peeling plate 21. . Furthermore, a pulley 23 is formed at the end of the platen 20, and this pulley 23 and the pulley 2 of the pulse motor 12
4, a timing belt 25 is stretched. Note that the label 18 shown in FIG. 10 is an inspection label 18a.

Next, the structure and operation of the thermal head 14 will be explained with reference to FIGS. 3 and 4. First, the thermal head 14 has R1 to R256.
256 heating elements 26 are arranged in a direction perpendicular to the moving direction of the label 18, and these heating elements 26 are grouped into groups of 32 such as R1 to R32, R32 to R64, etc. 8 of COM1 to COM8
divided into groups. The common drive 15 is divided into four categories by four transistors 27, and COM1 is connected to the heating element 26 of COM8 and COM1. Similarly COM2 is COM7 and COM2
and COM3 is connected to heating element 26 with COM6.
Connected to heating element 26 with COM3, COM4
It is connected to the heating element 26 between COM5 and COM4.

Further, two data latch/picture signal drive circuits 28 and 29 are provided which operate in response to a data latch signal from the CPU 27 and a picture signal drive control signal from the picture signal drive 16.
The heating elements 26 of COM1 to COM4 are connected to one of these, and the heating elements 26 of COM5 to COM8 are connected to the other.
is connected.

Therefore, actual printing is performed at the timing shown in FIG. That is, one line printing cycle is divided into four equal parts and 1/4 line feeding is performed by intermittent feeding with the pulse motor 12.
COM1, COM8, COM2 for each 1/4 line feed
energize the heating elements 26 of and COM7, COM3 and COM6, and COM4 and COM5.

Next, the operation will be explained based on the flowcharts of FIGS. 5 and 6. First, the fifth
The operation of the CPU 11 will be explained with reference to the diagram. After the power is turned on, each connected device is initialized, and the feed amount for controlling the print position and print format on the label 18 is transferred to the CPU 27, which controls the printer. Thereafter, the display on the display/key device 6 is scanned and the main routine is entered. In this main routine, data from the weighing section 2 is taken in, the state of the mode changeover switch 3 is read, and modes such as fixed amount issue mode, inspection and settlement mode, setting mode, etc. are set. Further, the key information of the display/key device 6 is taken in and processed.

After this, if it is in the weighing mode, the data in the weighing section 2 is multiplied by the unit price to obtain the price, and when the conditions for issuing the label 18 are set, the print F is set to 1, and data such as the price is output to the display/key device 6. and display it.
If print F is 1, the status of the printing device is checked, and if printing is OK, print data is set and transferred to the CPU 27. Thereafter, print F is reset to 0 and the process returns to the main routine.

Also, if the mode is the inspection payment mode, it is determined that the inspection payment is F, and if it is not "0", it checks the status of the printing device, and if printing is OK, it sets the print data and transfers this to the CPU 27. . Thereafter, the inspection settlement F is reset to 0 and the process returns to the main routine. Furthermore, if the mode is the setting mode, each setting task is performed and the process returns to the main routine.

Next, the operation of the CPU 27 that controls the printer will be explained based on FIG. After the power is turned on, each connected device is initialized, and the feed amount for controlling the print format, print position, etc. on the label 18 is received from the CPU 11, and the main routine is entered. In the main routine, it is first determined whether or not paper is being fed, and if it is paper feeding, the pulse motor drive 13 is driven, the pulse motor 12 is rotated, and the process returns to the main routine. At this time, if paper is not being fed, data from the CPU 11 is received. If this data is the feed amount,
Process the data and return to the main routine. If this is print data, the data is processed, a print pattern is generated on the print buffer 10, and printed, and the process returns to the main routine.

Next, each subroutine will be explained based on FIGS. 7 to 10. First, in key processing, in the setting mode, a PLU number is set and this number is stored in memory. After this, the product code number,
The product name, unit price, tare weight, and validity period are each set and stored in memory. If there is an issue key here, the setting label F is set to 1 and the process returns. In the setting task shown in Figure 8, this setting label F is 1.
In this case, check the status of the printing device, and if there is a label in the label detector 11, the label will not be issued.
If it is not OK, loop here until printing is OK. When label issuance is OK, the setting data is called from the memory, the data is transferred to the CPU 2, the setting label F is reset to 0, and the process returns. After receiving this setting data, the CPU 27 clears the print buffer 10 using the print buffer set shown in FIG. 9, and then prints a print pattern as shown in FIG. generate. Thereafter, in a print routine, the pattern on the print buffer 10 is used as the label 18, and an inspection label 18a is printed and issued.

Next, a modification of the setting work will be explained based on FIG. First, if the setting label F is set to 1, the inspection label issuing switch 3a is read. This inspection label issuing switch 3a
If ON, check label 18 as in the above case.
A is issued.

Further, still another example of the setting work will be explained based on FIG. First, if the setting label F is set to 1, the status of the printing device is checked. Here, when the label detector 11 detects the label 18, the set label F is reset to 0 without outputting data to the CPU 27, and the process returns. Therefore, the inspection label 18a is not issued. Further, when the label detector 11 does not detect the label 18, the inspection label 18 is detected as described above.
Issue 8a.

Effects of the Invention Since the present invention is configured as described above, the PLU
When data is set in the memory 5, an inspection label 18a with all of the setting data printed on it is issued.You can check the settings by looking at the printed contents of this inspection label 18a, and you can also print them on the mount. You can easily create a list of settings by pasting them on a file, etc., and changes can be made easily.
