Abstract

PURPOSE:To simplify data setting work by receiving automatically data transmitted from an apparatus designated to be a transmitting side through an inline line by the apparatus designated to be a receiving side. CONSTITUTION:Four sets of electronic charging balances 1 designated to be receiving side balances receive almost simultaneously transmission data from one set of the electronic charging balance 1 designated to be a transmitting side balance without switching a mode switch 27 to a receiving mode. Accordingly, an operator needs only to go to one set of the electronic charging balance 1 designated to be the transmitting side balance and instruct to set and transmit the data for a commodity file 14, and the same data is set for the commodity files 14 of the other electronic charging balances 1 as well. Thus, the operator need not go to every receiving side apparatus, and the data setting work can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a product sales data processing device such as an electronic cash register or an electronic price scale.

[Conventional technology] For example, an electronic price scale has a product file in which product data such as product name and unit price is set corresponding to the code of each product, and when the code of the product to be sold is entered from the keyboard, the above Read the corresponding product data from the product file. When the weighing unit performs weighing in this state, the price is calculated from the weight value and the read unit price, the sales are registered in the memory, and the product name, price, etc. are printed and displayed. .

By the way, conventionally, in stores that use multiple electronic price 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 the scale, the following simple inline method is known. That is, each electronic price scale is provided with an interface for connecting an inline line, and the electronic price scales are connected to each other via an inline line when setting a product. Then, any one scale is designated as the transmitting scale, and several other scales are designated as the receiving scales.

In this state, first, the data for the product file is manually entered using the keyboard of the sending scale, and this setting data is recorded on a recording medium by the recorder provided on the sending side lever. Next, the operation mode of the transmitter scale is set to transmission mode, and the operation mode of the receiver scale is set to reception mode. Then, the data recorded on the recording medium is transmitted from the transmitter scale to all other receiver scales via an inline line. As a result, other receiving scales set the data received through the inline line in their own product files.

[Problems to be Solved by the Invention] However, in the conventional simple in-line method described above, it is necessary to switch the equipment such as a scale designated on the transmitting side to the transmitting mode, and at the same time switch the equipment designated on the receiving side to the receiving mode. In addition, an operator must be present not only at the transmitting device but also at each receiving device, which is troublesome.

Therefore, the present invention enables a device designated as a receiving side to automatically receive data sent from a device designated as a sending side through an inline line, thereby eliminating the need for an operator to go to each receiving side device. The present invention aims to provide a product sales data processing device that can simplify data setting work.

[Means for Solving the Problems] The present invention provides mode selection means for selecting various business modes such as registration mode, setting mode, transmission mode, and reception mode, line connection means for connecting an inline line, and storage of setting data. It has a storage means and an input means for inputting information regarding the sales product, and when the registration mode is selected, registers the product sales data obtained from the information input by the input means based on the setting data stored by the storage means. In the product sales data processing device, when the transmission mode is selected, the data transmission means transmits the setting data stored in the storage means through the inline port connected by the line connection means, and the data transmission means determines whether or not data is received through the inline line. a means for determining the presence or absence of data; an automatic reception mode switching means for automatically switching the business mode to a reception mode when the determination means determines that data has been received; and data setting control means for storing the setting data received through the inline line in the storage means.

[Function] With the product sales data processing device having such a configuration, by selecting the transmission mode using the mode selection means, the setting data that is specified as the sending side device and stored in the storage means can be transmitted to other devices through the inline line. It is sent all at once to all receiving devices. On the other hand, if the other receiving side equipment detects that the reception of data through the inline line is interrupted by the data presence/absence determining means, the business mode is automatically switched to the receiving mode, and the received data is stored in the storage means. .

[Example] An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, five electronic price scales 1 are used as product sales data processing devices as shown in FIG.
A simple inline system in which electronic fare scales 1 can be connected to each other via an inline line 2 will be described.

FIG. 2 is a control block diagram of the electronic fare scale 1. As shown in FIG.

In the same figure, reference numeral 11 denotes a CPU (central processing unit) as the main body of the control unit, and according to a preset program, a ROM 12, a RAM] 3, a storage unit for product files 14, a recorder interface 15, an inline interface 16, and an inline interface 16. /D (analog/digital)

As shown in FIG. 3, a mode switch 27 is connected as a mode selection means for selecting and specifying various business modes as charge scales such as the registration mode, setting mode, transmission mode, reception mode, etc. The CPU 11 is notified by inputting a selection designation signal.

Therefore, after the power is turned on, the CPU 11 stores the ROM 12.
It is controlled to execute a process not shown in FIG. 4 according to the program data contained within. That is, as ST (step)], it is determined from the state of the ■/○ boat 21 whether or not the business mode has been changed by the mode switch 27. Then, when the business mode is switched, it is checked which business mode has been selected and designated, and the processing corresponding to the corresponding business mode is executed.

Here, when the setting mode is selected and specified in ST2, the selected setting work content is checked by key input from the keyboard 24. When it is detected that the product data setting (change) task in [Product File] 4 has been selected, the keyboard 24 is
The input key signal is taken in from the input key signal, and data corresponding to this 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, each product data set in the product file 14 is read, and the recorder interface 15 is controlled to send each product data to the tape recorder 22, and the tape recorder 22 records the data in a cassette. Record it on tape. After that, return to ST.

On the other hand, when the transmission mode is selected and specified in ST3, the transmission item selected by key input from the keyboard 24 is checked. Then, create header text according to the transmission item. Next, the transmission data text corresponding to the transmission item is edited, and the above-mentioned "transmission text" and "transmission data text" are sequentially transmitted to the inline line 2 via the inline interface 16. Then, after editing and transmitting the transmission data text according to the corresponding transmission item and editing and transmitting the end text, the process returns to STI. (Data Transmission Means) If mode switching has not been performed in the STI, the normal weighing operation according to the currently selected operation mode is executed. 4u L At this time, in ST4, it is determined by the inline interface 16 whether or not a header text transmitted from another electronic fare scale through the inline line 2 has been received (data presence/absence determining means). When it is determined that the header text has been received, the currently executing business mode is temporarily interrupted and 1] dynamically switches to the reception mode (automatic reception mode switching means). Thereafter, each time a text is received via the inline interface]6, the content is checked, and if it is a transmission data text, the data in the text is set in the storage section (data setting control means).

If the received text is the end text, it is determined whether or not the text reception process was performed normally, and when the text reception process is completed normally, the business mode is returned to the previous mode and the process returns to STI.

Fork 1〕 Executes error handling upon normal termination.

In this embodiment with such a configuration, when setting the same product data in the product file 14 of each electronic price scale 1, first, the inline line 2 is connected to the inline interface 16 of each electronic price scale 1. . Then, any one scale is designated as the transmitting scale, the remaining four scales are designated as the receiving scale, and the mode switch 27 of the transmitting scale is switched to the setting mode. In this state, product data is set in the product file 14 by operating a predetermined key on the keyboard 24. When the data setting is completed, the contents of ``1 product file'' 4 are recorded on the cassette tape by the tape recorder 22.

Next, the mode switch 27 of the sending scale is switched to the sending mode. In this state, when data transmission of the product file]4 is commanded by operating a predetermined key on the keyboard 24, the corresponding header text is first created, and then the transmission pig text is edited using the recorded data of the cassette tape played by the tape recorder 22. be done. And to this...
The text and the transmitted data text are collectively transmitted via the inline line 2 to each receiving scale. Note that the above operation is similar to the conventional simplified inline method.

On the other hand, each receiving scale automatically switches to receiving mode when the inline interface 16 receives the header text through the inline line 2. Thus, the transmission data text I. transmitted from the sending scale can be received, and the data in this reception text is set in the product file]4.

In this way, according to this embodiment, the 4
The electronic fare scales 1 can almost simultaneously receive transmissions from one electronic fare scale 1 designated as a transmitting scale without switching the mode switch 27 to the reception mode. Therefore, the operator goes to only one electronic price scale 1 designated as the sending scale and instructs the product file 14 to set and send data, and then updates the product files 14 of the remaining electronic price scales 1. Since the same de-3 overnight is set for the conventional simple inline method, there is no need for the operator to go to the receiving scale and switch the operating mode of the scale to the receiving mode, which is a burden on the operator. It is possible to reduce the amount of data setting and improve the efficiency of data setting work.

In the above embodiment, only the case where the setting data for the product file 14 is transferred to each receiving device at once is illustrated, but the same applies to the case where other setting data is transferred to each receiving device at once. . Further, although the above embodiment shows a case where a simple inline system is constructed using five electronic fare scales, the present invention is not limited to this. For example, a simple inline system is constructed using several electronic cash registers. Of course, the present invention can also be applied to cases where this method is adopted.

[Effects of the Invention] As detailed above, according to the present invention, data transmitted from a device designated as a transmitter through an inline line can be automatically received by a device designated as a receiver, and an operator can [4] By eliminating the need to go to each receiving device, it is possible to provide a product sales data processing device that can further simplify data setting work.
