Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data recall method for an electronic scale.

Electronic scales, for example, use a key dedicated to the product or a numeric keypad to input the product code, recall multiple unit price data stored for each product from memory, and calculate the price based on the recalled unit price and weight. It is now possible to calculate.

With the conventional method of recalling data on electronic scales, it was not possible to recall only the data from the memory built into the scale itself.For example, if the memory of the electronic scale was damaged, it could be replaced with another electronic scale. There is a drawback that the electronic scale cannot be used even if the functions other than memory are normal, and when dealing with a new product, all electronic scales that weigh that product will have the unit price of that product. It was necessary to memorize such data. Furthermore, if the memory of the electronic scale becomes saturated, the remaining data can be stored in the memory of another electronic scale, and two or more electronic scales can be installed in one place, depending on the product. It became necessary to use these electronic scales properly.

The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to obtain a data recall method that can commonly use the storage devices of a plurality of electronic scales, thereby eliminating the conventional drawbacks. It is something.

The main feature of this invention is that the storage devices of multiple electronic scales can be used in common by connecting multiple electronic scales to each other and reading data in the storage devices of other devices. This will be explained in more detail below.

FIG. 1 is a block diagram for implementing the method of the present invention when two electronic scales A and B are connected to each other. In this Figure 1, 1a, 1
Reference numeral b denotes a product specifying means, which is used to input a product code using a numeric keypad or a key dedicated to the product, and to retrieve data such as the unit price of the product from the storage device described below. Reference numerals 2a and 2b are central processing units (CPUs), and call receiving means 21a, which receive calls from other machines and signals from called parties;
21b, response transmitting means for responding when the own machine is called and transmitting data such as unit price stored in the memory device of the own machine, and 22a and 22b as programs, which operate as described below. do. 3
a and 3b are storage devices, and character pattern memory 31 stores in advance character patterns necessary for printing the product name as characters on a label;
a, 31b, and product memories 32a, 32b in which items necessary for price calculation and label printing, such as product unit price, product code, tare weight, etc., are stored in advance. 4a and 4b are interface circuits for connecting electronic scale A and electronic scale B. 5
a and 5b are weighing calculation devices that calculate the weight of the product, calculate the net weight from the weighed weight and the tare weight of the product output from the CPUs 2a and 2b, and calculate the net weight and the CPU 2a and 2b. The price is calculated from the unit price of the product output from.
6a and 6b are display devices that display the unit price, weight, and price; 7a and 7b are weight calculation devices 5a and 5b;
This is a label printer that prints the price, etc. output from the CPU 2a and the product name output from the CPU 2a, 2b on the label.

FIG. 2 is a flowchart showing the operation of the CPUs 2a and 2b when data stored in the storage device 3b of the electronic scale A is retrieved from the electronic scale A using the two electronic scales A and B. The operation will be explained below based on FIGS. 1 and 2. First, electronic scale A
When the code of the product is inputted to the product specifying means 7a, the electronic scale A searches its own storage device 3a to check whether there is data regarding the product.
If there is data for the above-mentioned product in the storage device 3a of the own machine, that data can be output to the weighing calculation unit 5a and label printer 7a, but if there is no data for the above-mentioned product in the storage device 3a of the own machine, the data is called. The receiving means 21a operates to search for data of another machine, that is, data in the storage device 3b of the electronic scale B in this case. In that case, first, when a request signal is sent to electronic scale B, the response transmission means 22b of electronic scale B is activated and sends back a response signal. At this time, if the response signal from electronic scale B is not received by electronic scale A due to a disconnection, for example, an error lamp (not shown) of electronic scale A lights up.
Then, data transmission between electronic scale B and electronic scale A becomes possible when electronic scale A receives the response signal, so electronic scale A then sends the product code to electronic scale B. When the data is sent, the data in the storage device 3b of electronic scale B is searched and the data corresponding to the product is sent to electronic scale A.
The CPU 2a receives the data and outputs it to the weighing calculation section 5a and the label printer 7a.The weighing calculation section 5a calculates the price, etc., and displays it on the display device 6a, and the price, product name, etc. are displayed on the label printer. It is printed on the label at step 7a. However, at this time, if there is no corresponding data in the storage device 3b of electronic scale B, a signal is sent from electronic scale B to electronic scale A indicating that there is no data for the corresponding product, and the error lamp of electronic scale A lights up. Light.

Although only the case where the electronic scale A calls the electronic scale B has been described above, the electronic scale A also responds to the transmission means 2.
Electronic scale 2a is also equipped with a call receiving means 21b, and electronic scale B can naturally call electronic scale A. Moreover, although the case where two electronic scales are used has been described, the case where two or more electronic scales are used can be similarly considered. In this case, for which electronic scale to call, a dedicated call key may be provided, or an automatic call device may be provided to call the plurality of other scales in sequence.

In addition, the product memories 32a and 32b are equipped with a total area for each product, so that weight, price, etc. can be added and stored for each weighed product, and even when a total print command is issued. As described above, the calling device is operated to call up the tally results and print them out using the label printers 7a, 7b or journal printer (not shown).

As explained above, this invention allows the storage devices of multiple electronic scales to be shared, so even if the storage device of one electronic scale fails, the storage device of another device can be used and new product data can be stored. It is sufficient to store the information in one of the multiple devices. Moreover, even if the number of products increases, the data on the products can be stored in a distributed manner in the storage devices of the plurality of electronic scales, so that the electronic scales can be used efficiently.
