Description

TECHNICAL FIELD The present invention relates to a product data registration device capable of sequentially registering a large number of set product data in a plurality of electronic scales.

(Prior Art) An electronic scale capable of pre-registering product data such as unit price, tare weight, and effective period of a product to be measured for each item has been proposed by JP-A-55-142216. Also, connect a plurality of slave electronic scales to the master electronic scale and memorize them so that the same product data as the product data that is typed into the storage device of the master electronic scale is copied to the storage device of each slave electronic scale. In addition, a POS system in which each slave electronic balance uses the product data stored in its own storage device is described in Japanese Patent Laid-Open No. 61-90297.

Further, there is also a method for calling data of an electronic scale, in which a plurality of electronic scales as described above are connected so that registered (stored) product data can be called from any of the electronic scales. It is proposed by the publication 34121.

When such a data calling method is used, the storage device of each electronic scale can be used in common, so that a large number of product data can be distributed and stored in each electronic scale, and the storage efficiency of the storage device is improved. there were.

(Problems of Prior Art) However, in such a data calling method,
There was a problem that the registration of product data was complicated. That is, (1) since multiple electronic scales are installed in different places,
The operator uses the first electronic scale to register the product data one after another using the numeric keypad and the function keys. When the storage device runs out of memory, the registration operation is terminated, and the item name at the end of registration is recorded. Next, it moves to the place where the second electronic scale is installed, and the items that could not be registered in the first electronic scale are sequentially registered. If the memory is over, the registration work of the electronic scale is terminated. After that, the same operation is repeated to complete the registration of all the products.

(2) When some product data is already registered in each electronic scale, the operator searches for an electronic scale having an unregistered area in the storage device and registers new product data in the electronic scale. .

As described above, when the operator registers the product data in each electronic scale, the item name at the time of the memory overflow is stored or recorded, and the operator moves to the next electronic scale to perform the registration work and perform duplicate registration. Are prevented.

Further, whether or not there is an unregistered area in the electronic scale, that is, whether or not new product data can be registered is determined only after the electronic scale is once set in the registration mode. This is because the electronic scale informs the operator of the memory over alarm display when all the input product data for one item cannot be stored, that is, when only a part of the data can be stored. is there. Therefore, it takes time to check whether registration is possible.

As described above, when the conventional electronic scale data calling method is used, the registration work of the product data is complicated.

(Object of the invention) The present invention aims to solve the problems of the prior art as described above, and is provided with means for inputting and storing product data of a large number of items, and the stored product data is automatically and sequentially stored. A registration device for merchandise data is provided which simplifies the registration work for each electronic scale by transmitting and registering to an electronic scale.

(Summary of the Invention) The product data registration apparatus of the present invention connects a plurality of electronic scales to a controller that stores product data for each item, and the controller has means for specifying an electronic scale to communicate with. , A means for transmitting product data to the specified electronic scale, while each electronic scale is provided with means for storing the received product data in communication with the controller in an unregistered area In the registration device, the electronic scale compares the capacity of the received product data with the storage capacity of its own unregistered area, and if the capacity is insufficient, sends a storage disable signal to the controller, If it is not insufficient, it has a means to store product data in the unregistered area,
On the other hand, the controller is characterized in that it has means for specifying another electronic scale and sequentially transmitting unregistered merchandise data to the scale if there is a non-storable signal from the electronic scale during communication.

There is.

FIG. 3 is a schematic block diagram of each electronic scale. As shown in the figure, each electronic scale uses a weight detection unit using a load cell, an A / D converter for converting an analog signal into a digital signal, a key input unit consisting of a numeric keypad and function keys, a microcomputer, etc. , A calculation control unit that calculates a price and the like from the weight and the unit price, a display unit that displays the weight, the unit price, and the price, and a printer that prints a predetermined item on a label or receipt. The arithmetic control unit is provided with a central processing unit (CPU), an input / output port (I / O), a memory (RAM) backed up by the DC power supply E, and a memory (ROM) storing a control program and the like. .

FIG. 4 is an explanatory diagram of a storage example of the buffer memory in the RAM in the controller B. In this example, product data such as a product name character code, a unit price, and a tare weight are stored for each product with call codes 1 to 100 in one block.

5 and 6 show the RAM in the first and second electronic scales, respectively.
3 is an explanatory diagram of a storage example of a registration memory in FIG. In this example, the first electronic scale stores the product data of the call codes 1 to 70, and the second electronic scale stores the call codes 71 to 100.
The product data up to is stored and it is shown that there is an unregistered area in the second electronic scale.

FIG. 7 is a flowchart showing the processing procedure of the present invention. The process of registering product data will be described below with reference to this flowchart.

(1) Enter product data using a computer keyboard (step S1) and store it by item (step S1).
2), it is checked whether all the product data have been input (step S3).

(2) When the input of the product data of all the items is completed (“Yes” in step S3), the product data for one block, for example, the product data for 100 items is transmitted to the controller B (step S4), and the controller It is checked whether or not a data request signal has been received from B (steps S5 and S6). Since the data request signal has not been transmitted from the controller B yet, the computer A is in the waiting state in the loop of steps S5 and S6. (3) The controller B receives the product data for one block from the computer A and stores it in the buffer memory (RAM) (step P1). This is the state shown in FIG.

In step P2, since no product data has been transmitted from the controller B yet, the determination is NO, and the product data for one item in the designation of the scale number 1 and the buffer memory (RAM) (since this is the first process, The product data of call code 1) is transmitted to each electronic scale (step P3).

Each electronic scale receives this (steps A1, B1,
…), And check if it matches with your own scale number (steps A2, B2…). Step A2 of the first electronic scale
Processing becomes YES, the number of bytes of the received product data is compared with the number of bytes of the unregistered area of the registered memory,
It is checked whether or not it can be stored (step A3). If it can be stored, the received product data is stored in the registration memory (step S4), and a storage completion signal is transmitted to the controller B (step A5).

(4) The controller B receives the signal from the first electronic scale and confirms that it is a storage completion signal (step
P5). Next, return to the process of step P2, and
The process of P3 → A1 to A5 → P4 → P5 is repeated to sequentially register the product data from the controller B in the first electronic scale (see FIG. 5).

(5) In this example, the item with the calling number 71 runs out of memory (step A3), and a storage disable signal is transmitted to controller B (step A6).

(6) The controller B specifies the scale number 2 by receiving the storage disable signal (steps P4 and P5), and the product data that could not be stored (in this case, the call code that could not be stored in the first electronic scale). 71 product data) is transmitted to each electronic scale (step P6).

(7) Each electronic scale receives the signal from the controller B (steps A1, B1 ...) And checks whether or not it matches with its own scale number (steps A2, B2 ...). Only step B2 of the second electronic scale becomes YES, and thereafter, steps B3 → B4 → B5 of controller B, steps P9 → P10 → P7 are executed in the same manner as the first electronic scale, and scale number 2 and buffer The product data of the next item in the memory (RAM) (product data of calling code 72) is transmitted to each electronic scale (step P
8).

The second electronic scale executes the processes of steps B1 to B5, and the controller B executes the processes of steps P9 and P10.

(8) For each item data, follow steps P7 → P8 →
The process of B1 to B5 → P9 → P10 is repeated to register the product data from the controller B to the second electronic scale (see FIG. 6).

(9) When all the product data (100 items in this example) in the buffer memory (RAM) of the controller B is transmitted, the determination in step P7 becomes YES and the controller B
Sends a data request signal to computer A to request the next block of product data (step P1).
1).

(10) The computer A receives the signal from the controller B (step S5), confirms that the signal is a data request signal (step S6), and stores the product data (step S7). One block of product data (for example, product data of calling codes 101 to 200) is transmitted to the controller B (step S4).

(11) The controller B receives one block of product data and stores it in the buffer memory (RAM) (step P
1), the processes of steps P2 and P3 are executed to specify the scale number 1 and send the product data for one item to the electronic scale.

The first electronic scale receives this signal (step A1),
After that, the process of steps A2 → A3 → A6 is executed, and the storage disable signal is transmitted to the controller B.

The controller receives this signal (step P4),
After that, the processes of steps P5 to P6 are executed to specify the scale number 2 and the product data for one item that cannot be stored in the first electronic scale (in this case, the product data of the item with the calling code 101). To the electronic scale.

Next, the second electronic balance receives the signal from the controller B (step B1), and thereafter executes the processing of steps B2 → B3 → B4 to store the commodity data of the item of the calling code 101. When storage is completed, a storage completion signal is sent to controller B.
To (step B5).

When the controller B receives the signal from the second electronic scale (step P9), it confirms that the signal is a storage completion signal (step P10), and returns to the process of step P7. Less than,
By repeating the loop process of steps P7 → P8 → B1 to B5 → P9 → P10 → P7, the product data is registered from the controller B to the second electronic scale.

(12) After that, similarly, all the product data input to the computer A are sequentially registered in the third, fourth, ... Electronic scales.

FIG. 8 is a flow chart showing a processing procedure for mutually calling and responding to product data between electronic scales.

Hereinafter, description will be given along this flowchart. The memory of each electronic scale is provided with areas such as a registration memory, a setting memory, and a scale number memory.

(1) When a certain product is weighed with, for example, an electronic scale of scale number 2, the call number (code) corresponding to the product is entered and the call key of the function key is turned on (step Y1). Next, the registration memory is searched by the calling number entered by the ten-key pad (step Y2), and it is checked whether or not the corresponding calling number exists in the relevant electronic scale (in this case, the electronic scale of scale number 2). (Step Y3).

(2) If the corresponding calling number is present in the electronic scale with the scale number 2, for example, the registration data is temporarily transferred to the setting memory and stored (step Y9), and the scale number 2 of the electronic scale is measured. It is stored in the number memory (step Y10).
Then, the price is calculated by multiplying the measured value by the unit price of the product stored in the setting memory (step Y16), and the label or receipt is printed (step Y17). next,
Check the contents of the scale number memory (step Y18),
If it is the scale number, the price is added and stored in the counting memory corresponding to the calling number (step Y19).

(3) If it is determined in step Y3 that the calling number corresponding to the product is not present in the electronic scale of scale number 2, it is confirmed in step Y4 whether the bus line is in communication. If the bus line is open, the process proceeds to step Y5, in which the smallest scale number (in this case, scale number 1 to scale number 3 of the electronic scale is skipped to scale number 3 ... n). Send to the bus line.

On the response side, check that there is a scale number signal on the bus line (step X1), receive the scale number signal from the bus line (step X2), check whether the scale number signals match, and if not, select another. If yes (step X3), the reception completion signal is transmitted to the bus line (step X4).

(4) When the calling side receives the reception completion signal (step
Y7), the data type code (in this case, the calling number code) and the calling number are transmitted to the bus line (step Y
8). The response side confirms that the bus line has the data type code (step X5), and receives and stores the data type code and the data (call number) (step X6).

Next, in step X7, it is checked which data type code has expired. Since the calling number code has been received in this example, the registered memory is searched by the calling number in step X8.

(5) If the calling number does not exist, the code without the calling number is transmitted to the bus line (step X11). If the calling number exists, the code with the calling number and the registration corresponding to this calling number are registered. The registered data and the registered data are transmitted to the bus line (step X10). On the calling side, it is checked whether or not the presence / absence code signal is received (step Y11). If this signal is received, the step with the calling number is step Y13, and the absence code is the step. Continue to Y14.

(6) In step Y13, the registration data sent from the response side electronic scale is stored in the setting memory of the calling side (electronic scale of scale number 2), and the scale number of the response side electronic scale is stored in the scale number memory. To memorize. If it is judged in step Y12 that the signal of the code without calling number is received, step Y14
Check if it is the last frame number with, and if the process has not finished up to the last frame number,
Return to Y6 to continue processing for the next scale number. When the call number corresponding to the last scale number is not found, an alarm is displayed as if there is any error (step Y15).

(7) In step Y18, the contents of the balance number memory are
When it is determined that the electronic scale, for which the call number was present, was the frame number 1, instead of the scale number 2 of the scale being measured, the price tabulation process from step Y20 is performed. In step Y20, it is determined whether or not the bus line is in communication. If the bus line is vacant, the balance number stored in the balance number memory is transmitted to the bus line in step Y21. The response side performs the processing of steps X1 to X4 again, and transmits the reception completion signal to the bus line. When the calling side receives the reception completion signal (step Y22), the data type code (price code in this case), the price and the calling number are transmitted to the bus line in step Y23.

The responder performs steps X5 and X6, then step X7
Since the price code has been transmitted in the determination of the data type code, the price is added and stored in the total memory corresponding to the calling number in step X12. That is, scale number 2
Although the registration data of the product weighed by the electronic scale of No. 1 existed in the electronic scale of No. 1, the electronic scale of No. 2 and the electronic scale of No. 1 mutually communicated using the common bus line. By transmitting and receiving, the price is calculated by the electronic scale with the scale number 2 and a label is issued, and the sales of the product can be aggregated with the electronic scale with the scale number 1.

Finally, in step X13, the addition storage completion signal on the response side is transmitted to the bus line, and the addition side storage completion signal is received on the calling side to end the series of operations.

In the above description, the electronic scale with the scale number 2 is changed to the scale number 1
It calls the electronic scale of, but in reality, all the electronic scales in the set have two programs for calling and responding,
Each person can freely call and respond.

Next, the process of changing product data will be described.

(1) Using the numeric keypad and function keys of the controller B, input the call code and the product data to be changed, send the product data to be changed to the electronic scale storing the call code, and change the registration data To do.

(2) Or, using the keyboard of the computer A, input the call code and the product data to be changed, and send the product data to be changed to the electronic scale storing the call code via the controller B. Change the registration data.

The above description is an example in which the computer A and the controller B are directly connected by a bus line. However, the product data input by the computer A is once recorded on a cassette tape, and the cassette tape recorder is connected to the controller to make a cassette tape. It is also possible to configure the buffer memory (RAM) of the controller B to store the product data recorded in the.

Further, the function of the controller B can be incorporated in the computer A, and the computer A and each electronic scale can be directly connected by a bus line to perform the registration process of the product data.

Further, the function of the controller B can be incorporated in a specific electronic scale (for example, the first electronic scale. In this case, the computer A and the specific electronic scale can be directly connected to each other, or the computer A can be used. The input product data is once recorded on a cassette tape and stored in the buffer memory of a specific electronic scale from the cassette tape recorder.

(Effects of the Invention) As described above, according to the product data registration apparatus of the present invention, the electronic scale may have insufficient capacity as the capacity of the received product data and the storage capacity of its own unregistered area. If
Means for storing the merchandise data in the unregistered area is sent if the memory-disabled signal is sent to the controller and the capacity is not insufficient. Since there is a means to specify the electronic scales and to send the product data that has not been registered to the scales in sequence, the controller specifies each electronic scale and the product data is automatically sequenced without memory overflow. You can register. Therefore, unlike the conventional case, it is not necessary for the operator to check whether or not each electronic scale has an unregistered area and individually check whether or not new product data can be registered. Registration work to each electronic scale can be simplified, and duplicate registration due to human error can be prevented.
