Read the corresponding product data from the file. When weighing is performed in the balance section in this state, the price is calculated from the weight value and the read unit price, sales are registered in the memory, and the product name, price, etc. are printed and displayed.

By the way, conventionally, in a store that uses multiple electronic toll scales with the same product data set in the product file,
In order to simplify the setting work of each product data for the product file of each scale, the following simple inline system is known. That is, each electronic charge scale is provided with an interface for connecting an in-line line,
When setting the product data, each electronic charge scale is connected to each other via an in-line line. Then, any one of the scales is designated as the transmission side scale and several other scales are designated as the reception side scales. In this state, first, the data of the product file is manually set using the keyboard of the transmitting scale, and the setting data is recorded in the recording medium by the recorder provided in the transmitting scale. Next, the business mode of the transmitting scale is set to the transmission mode, and the business mode of the receiving scale is set to the reception mode. Then, the data recorded on the recording medium from the transmitting scale is collectively transmitted to all other receiving scales through the in-line line. As a result, the other receiving scale sets the data received through the in-line line in its own product file.

[Problems to be Solved by the Invention] However, in the above-described conventional simple in-line method, it is necessary to switch a device such as a scale specified on the transmission side to the transmission mode and a device specified to the reception side to the reception mode. In addition, the operator had to go not only to the transmitting device but also to each receiving device, which was troublesome.

Therefore, the present invention, the device specified to the receiving side can automatically receive the data transmitted from the device specified to the transmitting side through the in-line line, by eliminating the need for the operator to go to each receiving side device, An object of the present invention is to provide a product sales data processing device capable of simplifying the data setting work.

[Means for Solving the Problem] The present invention stores a mode selecting means for selecting various business modes such as a registration mode, a setting mode, a transmitting mode, and a receiving mode, a line connecting means for connecting an inline line, and a setting mode. It has a storage means and an input means for inputting information about a sale product, and when the registration mode is selected, the product sales data obtained from the information input by the input means based on the setting data stored by the storage means is registered. In the product sales data processing device, when the transmission mode is selected, it is judged whether the data is transmitted through the inline line connected by the line connection means and the data transmission means for transmitting the setting data stored by the storage means, and whether the data is received through the inline line. Data presence / absence determining means to perform, and the business mode when the presence of data is determined by this determining means Equipped with automatic reception mode switching means for automatically switching to the reception mode, and data setting control means for storing the setting data received through the inline line in the storage means in the state where the automatic reception mode is selected by the switching means. Is.

[Operation] With the product sales data processing device having such a configuration,
When the transmission mode is selected by the mode selection means, the setting data designated by the transmission side device and stored in the storage means is collectively transmitted to all other reception side devices through the in-line line. On the other hand, in the other receiving side device, when the data presence / absence determining means determines that the data is received through the in-line line, the business mode is automatically switched to the receiving mode and the received data is set in the storage means.

The printer 26 is drive-controlled to display characters, numbers, etc. corresponding to the print data sent from the CPU 11. Print on recording paper. Above I / O port 21
As shown in FIG. 3, a mode switch 27 is connected as a mode selection means for selecting and specifying various business modes as a charge balance such as the registration mode, the setting mode, the transmission mode, and the reception mode. The selection designation signal from the switch 27 is input to notify the CPU 11.

Therefore, the CPU 11 is controlled to execute the processing shown in FIG. 4 in accordance with the program data in the ROM 12 after the power is turned on. That is, as ST (step) 1
It is determined from the state of the I / O port 21 whether the business mode has been switched by the mode switch 27. Then, when the business mode is switched, it is checked which business mode is selected and designated, and the process corresponding to the corresponding business mode is executed.

Here, when the setting mode is selected and designated as ST2, the contents of the setting work selected by the key input from the keyboard 24 are examined. Then, when it is detected that the operation of setting (changing) the product data in the product file 14 is selected, the input key signal from the keyboard 24 is taken in through the keyboard circuit 18 and the data corresponding to the input key signal is input. . Then, the input data is set in the corresponding product data area of the product file 14. Such processing is repeated until data indicating the end of setting is input as data corresponding to the input key signal. When the data indicating the end of the setting is input, the product data set in the product file 14 is read, and the product interface 14 controls the recorder interface 15 to read the product data.

On the other hand, when the transmission mode is selected and designated as ST3, the transmission item selected by the key input from the keyboard 24 is checked. Then, a header text corresponding to the transmission item is created. Then, the transmission data text corresponding to the transmission item is edited, and the header text and the transmission data text are sequentially transmitted to the inline line 2 via the inline interface 16. When the editing / transmission of the transmission data text corresponding to the corresponding transmission item is completed and the end text is edited / transmission, the process returns to ST1. (Data transmission means) If the mode is not switched in ST1, the normal weighing work according to the currently selected and designated work mode is executed. However, at this time, in ST4, it is determined by the inline interface 16 whether or not the header text transmitted from the other electronic charge balance 1 is received through the inline line 2 (data presence / absence determining means). When it is determined that the header text has been received, the currently-executed business mode is temporarily suspended and automatically switched to the reception mode (automatic reception mode switching means). Then inline interface
Every time the text is received via 16, the content is checked, and if it is the transmission data text, the data in the text is set in the storage unit (data setting control means). If the received text is the end text, it is determined whether or not the text receiving process is normally performed, and when the text is normally terminated, the business mode is returned to the immediately preceding mode and the process returns to ST1. Error processing is executed at abnormal end.

In this embodiment having such a configuration, when the same product data is set in the product file 14 of each electronic charge balance 1, first, the inline line 2 is connected to the inline interface 16 of each electronic charge balance 1. . And any one

In this state, the product data is set in the product file 14 by operating a predetermined key of the keyboard 24. When the data setting is completed, the contents of the product file 14 are recorded on the cassette tape by the tape recorder 22.

Next, the mode switch 27 of the transmitting scale is switched to the transmitting mode. In this state, when the keyboard 24 is instructed to transmit the data of the merchandise file 14 by a predetermined key operation, the corresponding header text is first created, and then the tape recorder 22
The transmitted data text is edited by the recorded data of the cassette tape reproduced by. Then, the header text and the transmission data text are collectively transmitted to each receiving scale via the inline line 2. The above operation is similar to that of the conventional simple inline method.

On the other hand, in each receiving side scale, when the header text is received through the inline line 2 by the inline interface 16, it is automatically switched to the receiving mode. Then, the transmission data text transmitted from the transmitting scale can be received, and the data in this reception text is stored in the product file 14
Is set to

As described above, according to the present embodiment, the four electronic toll scales 1 designated as the receiving side scale have the one electronic toll scale 1 designated as the transmitting side scale without switching the mode switch 27 to the receiving mode. The transmission data from 1 can be received almost simultaneously. Therefore, one electronic charge balance 1 designated as the sender scale
Only by the operator going to command the setting and transmission of data for the product file 14, the same data is set for the product file 14 of the remaining electronic charge balance 1, so that the conventional simple inline method is used. Compared with the above, the operator does not need to go to the receiving scale to switch the work mode of the scale to the receiving mode, which can reduce the burden on the operator and improve the efficiency of data setting work.

It should be noted that, in the above embodiment, only the case of collectively transferring the setting data for the product file 14 to each receiving side device is illustrated, but the same applies to the case of collectively transferring the other setting data to each receiving side device. . Further, in the above-mentioned embodiment, the case where the simple type inline system is constructed by the five electronic charge scales has been shown, but the present invention is not limited to this, and for example, the simple type inline system can be used for several electronic cash registers.
