Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a journal printer having a plurality of electronic scales with different print formats as data sources.

Generally, with electronic scales equipped with a label printer, the unit price, price, etc. of each item is printed out on a label using a label printer, and a journal printer is used as an external device to print out the sales totals for a certain period of time (a certain period of time, one day, etc.). This journal printer also prints out the sales, etc. for the above-mentioned fixed period, which are written in the storage device or register, on journal paper when necessary. By the way, when printing with the above-mentioned journal printer, the print format may differ depending on the model of electronic scale. For example, in a journal printer linked to a certain model of electronic scale, the product name code and the sales total for that product name are printed on journal paper. Journal printers linked to other models of electronic scales print the product name code and the sales total for that product name on the next line.

In this case, the journal printer also began to use a special machine with a print format set according to the electronic scale, and one journal printer was always required for each electronic scale. .

This invention has been proposed in view of the above-mentioned conventional circumstances, and aims to eliminate the drawbacks of the conventional printer by providing a journal printer that can handle multiple electronic scales with different printing formats. be.

In this invention, the journal printer side is equipped with a model discrimination function, a data mode discrimination function, and a print format reading function, and the print format determined by the model and mode discriminated by the above two discrimination functions is read from the storage device. The main feature is that data from electronic scales can be printed in this format, and one unit can be compatible with many models of electronic scales with different printing formats, as shown in the drawings below. This will be explained in more detail based on.

FIG. 1 shows an overview of the invention as a block diagram of software or hardware functions.

In FIG. 1, 1a, 1b, . . . , 1n are a plurality of electronic scales with different printing formats, and 2 is a journal printer. Each of the above electronic scales 1a,

As shown in Figure 2, the printed data includes registration mode data, such as registered product code, unit price, validity period, etc. Da ₁ Da ₂ ...Dn ₁ , and aggregation mode data, i.e., the price for each measurement. data such as total weight and
Da ₂ Db ₂ ...Dn ₂ and label printing mode data, i.e. data printed by the label printer for each measurement (e.g. product code, unit price, price, etc.) Da ₃ Db ₃ ...
Dn _3, etc., and a mode signal S ₂ indicating the mode of the data is output at the beginning of each data. Furthermore, the model signal S ₁ is obtained by pressing the print key 10, and the mode signal S ₂ and print data D are obtained by pressing the mode selection keys 11, 12, 13 corresponding to each mode such as registration, tabulation, label printing, etc. It can be output by

The journal printer 2 is equipped with a control section 20 consisting of a model discrimination means 21, a mode discrimination means 22, and a reading means 26, and a storage device 23 described below that stores a print format determined by the model and mode. As shown in Fig. 2, 23 contains data Da ₁ ...Dn 1, Da ₂ ...Dn ₂ , each mode of registration, totalization, and label printing of the electronic scales 1a, 1b, ..., _1n .
Da ₃ …Dn ₃ corresponding printing formats
Memorize Pa ₁ ...Pn ₁ , Pa ₂ ...Pn ₂ , Pa ₃ ...Pn ₃ . Which electronic scale 1 is the journal printer 2 mentioned above?
The model determining means 21 determines whether the data is from a, 1b,..., 1n based on the model signal _S1 from the electronic scale, and the mode determining means 22 determines which mode the data is sent from. Is there a mode signal S ₂
The reading means 26 reads the storage device 23 according to the determination results of these two determining means.
The corresponding print format stored in the printer is read out, and the data D is printed out in that format. 24 is a printing control means, and 25 is a printing section, which includes a print head and its peripheral equipment, such as a paper feeding mechanism.

FIG. 3 shows a control section 20 comprising the above-mentioned model discriminating means 21, mode discriminating means 22, and reading means 26.
Applicable when executed on a central processing unit (CPU)
This is a flowchart showing the operation of the CPU.

First, the model determining means 21 reads the model signal _S1 outputted from the electronic scale, and determines from this the model that is sending the mode signal _S2 and print data D ( _F1 ).

Next, the mode determining means 2 reads the mode signal S ₂ to determine which mode the above data belongs to.
2 (F ₂ ), and according to the determination result, the reading means 26 reads out the corresponding print format from the storage device 23 and outputs it to the print control section 24 together with the sent data. controls the printing unit 25 to print the data on journal paper according to the print format (F ₃ ).
For example, when printing the data Da ₂ of the totalization mode of the electronic scale 1a, the print format Pa ₂ is read from the storage device 23. FIG. 4 shows an embodiment in which the present invention is implemented using hardware in the control section 20, and this control section 20 includes AND gates Ga ₁ , Ga ₂ , Ga ₃ , ..., Gn ₁ , Gn ₂ ,
These gates consist of GN ₃ and
Ga ₁ , Ga ₂ , Ga ₃ , . . . , Gn ₁ , Gn ₂ , Gn ₃ combine model discrimination means, mode discrimination means, and reading means. In this Figure 4, the AND gate
_{The model signal S 1, mode signal S 2 and data} Da ₁ from the electronic scale 1a, and print format Pa ₁ from the storage device 23 are input to Ga 1, and the AND gate
Ga ₂ has model signal S ₁ and mode signal from electronic scale 1.
S ₂ and data Da ₂ , and the print format Pa ₂ from the storage device 23 are input, and the AND gate Ga ₃ receives the model signal S ₁ , mode signal S ₂ , and data Da ₃ .
The print format Pa ₃ is input, and in the same way, the signal and data from the electronic scale 1b and the print format from the storage device 23 are input to the AND gates Gb ₁ , Gb ₂ , Gb ₃ , and the AND gates Gn ₁ , Gn ₂ ,
The signal and data from the electronic scale 1n and the print format from the storage device 23 are input to _Gn3 .

Here, for example, the mode signal from the electronic scale 1b
When S ₂ , data Db ₂ , and model signal S ₁ are output, AND gate Gb ₂ opens, and print format Pb ₂ output from the storage device 23 and the above data Db ₂ are output from AND gate Gb ₂ to control printing. The data _Db2 is input to the means 24 and is printed in the corresponding print format _Pb2 .

Fig. 5 shows an example of the connection means between the electronic scales 1a, 1b, ..., 1n and the journal printer 2, and a in Fig. 5 shows an example of connection means for connecting the electronic scales 1a, 1b, ..., 1n and the journal printer 2. Now, each time printing is completed for one electronic scale, it is connected to another electronic scale, and one journal printer can be moved to multiple electronic scales used in separate locations. This is effective when printing with Figure b is further systemized to include multiple electronic scales 1a, 1b,
. . , 1n and the journal printer 2 are always connected. Figure c shows the case where both are always connected as in case b above, but the print key 1 corresponding to each electronic scale is
0' and mode selection keys 11', 12', 13' are provided on the journal printer 2 side, and by pressing the print key 10', a specific electronic scale is called up and the model discrimination means 21 is activated. , the mode is selected by pressing the mode selection keys 11', 12', and 13', and the mode discriminating means 22
The digital balance is designed to operate in such a way that it is possible to output data in a desired mode from a desired electronic scale in a corresponding print format simply by operating the journal printer.

As explained above, this invention allows a single journal printer to print out various data from multiple electronic scales with different print formats in a predetermined print format, thereby increasing the flexibility of both the electronic scale and the journal printer. Economical efficiency can be improved.
