Description

[Detailed description of the invention]

Technical Field of the Invention The present invention provides a PLU for a label printer that has a large number of PLU memories containing various information such as unit price and tare.
This is related to the setting method. Technical background and problems Conventionally, in label printers that are connected to a scale and receive data from the scale and print the necessary information on a label and issue it, unit price, tare, expiration date, product name, product code, etc. are printed on PLU. There are some things that have a large number of memories (price backup memories). The operator's operation for such a label printer is to input PLUNo. using the key to call up the PLU, and when the item is placed on the scale, it will automatically issue a label with information such as unit price, weight, price, item name, etc. printed on it. , it is as simple as attaching this label to the product. However, some products are sold at a fixed price without being weighed, so it is necessary to have information such as A piece B yen in the PLU.
They have different unit prices and properties such as tail, book, cut, weight, and unit price, and have a large memory capacity. This state is shown in FIG. That is, the area for one PLUNo. in memory 1 is illustrated, and PLUNo. is the product code and product name.
Tare, unit price, validity period, A piece B yen, C piece D yen, E tail F yen, G book H yen, I cut J yen, LgM yen, NgO unit price, P unit price Q yen is displayed respectively. Here, since the area to be used for ~ is determined depending on its contents, it is necessary for each PLU No., and 32 bytes are required for 1 PLU.
Therefore, since the number of PLUs is usually 300 or 600, the memory capacity for the PLUs must be considerably large. OBJECTS OF THE INVENTION It is an object of the present invention to provide a PLU setting method for a label printer that requires a small capacity PLU memory. Summary of the Invention The present invention is a label printer that has a large number of PLU memories containing various types of information such as unit price and tare. A fixed amount PLU that has been memorized is provided, and in addition to areas such as PLU No., product code, and product name, unit data and amount data can be set.
Two information areas named Y and a designated area for storing the code of the flat rate PLU for specifying the contents of these information areas are set, and the information of the flat rate PLU based on the code set in these designated areas is stored. The present invention is characterized in that the information area of the PLU memory is called and the content of the information is specified. Therefore, even if there are many types of product units and their prices, the PLU memory stores two information areas X and Y and the code of the fixed price PLU for specifying the contents of these information areas. Fixed amount PLU if specified area exists
The system is configured in such a way that many types of specifications can be performed by calling from , and as a result, the overall memory capacity can be made extremely small. Embodiment of the Invention An embodiment of the present invention will be described with reference to FIGS. 2 and 3. First, scale 2 is a label printer.
It is connected to CPU3, and this CPU3 has ROM.
Program memory consisting of 4, consisting of RAM
A PLU memory 5, various keys 6, a mode changeover switch 7, a printer 8, and a display 9 are connected, respectively. Therefore, the PLU memory 5 is PLUNo.
The area of product code, product name, and expiration date is the same as the conventional one. However, the information area 10 that stores various information is
and Y〓〓, which consist of 4 bytes. Further, a designation area 11 for specifying the contents of the information area 10 is constituted by 1 byte as Z. For example, 00 is 01 in this specified area 11.
The following table shows the correspondence between these codes and the information area 10.

[Table] In such a configuration, at the time of setting, the mode changeover switch 7 is switched to the setting mode, and data is set in the X and Y information areas 10 using the keys 6.
Further, it is determined whether or not the key 6 has been pressed, and the corresponding code is input into the designated area 11. Therefore, when printing a label, switch the mode changeover switch 7 to the printing mode, and press the key 6 to turn on the PLU.
Call the PLU whose No. is entered. At this time, PLU
was called after determining the contents of designated area 11 of
Determine what type of PLU the PLU is,
Extract the data from the information area of Y and send it to printer 8.
and output to the display section 9. However, PLUNo., product code, product name,
The memory, excluding the validity period, is 5 bytes, compared to the conventional 32 bytes shown in Figure 1.
27 bytes less per PLU,
Approximately 8 kilobytes of memory is no longer needed for 300 PLU, and about 16 kilobytes for 600 PLU. Effects of the Invention The present invention provides a label printer that has a large number of PLU memories containing various information such as unit price and tare, and separates flat rate data, which is a combination of two pieces of information, unit data X and amount data Y, using codes. A fixed amount PLU that has been memorized is provided, and in addition to areas such as PLU No., product code, and product name, unit data and amount data can be set.
Two information areas Y and a designated area for storing the code of the flat rate PLU for specifying the contents of these information areas are set, and the information of the flat rate PLU based on the code set in these designated areas is stored. Since the information area of the PLU memory is called to specify the content of the information, the PLU
Even if there are many types of product units and their prices, the memory has two information areas X and Y and the fixed amount PLU for specifying the contents of these information areas.
If there is a designated area to store the code, a fixed amount will be charged.
Many types of specifications can be performed by calling from the PLU, and this has the effect that the capacity of Merry as a whole can be made extremely small.
