Description

The present invention relates to a product sales data processing device in which a terminal is connected to a file controller having a product information file.

[Prior Art] Conventionally, as a product sales data processing device, for example, a unit price and a product name are set corresponding to a product code attached to each product, and a cumulative sales amount area and a cumulative sales amount area are set. A file controller provided with a provided product information file, for example, a PLU file, is provided with a bar code scanner as a product code input means, and a terminal provided with a display and a printer, for example, an electronic cash register is connected. It has been known. When this device reads the product code attached to the product by the bar code scanner of the cash register, it inquires the product code to the file controller, and the file controller inquires from the cash register to the PLU.
Search for the corresponding product code from the file, read the unit price and product name corresponding to that product code, accumulate the unit price in the cumulative sales amount area, add +1 to the cumulative sales number area, and add the unit price and product name. Send to cash register. As a result, the cash register causes the display unit to display the received unit price and causes the printer to print out the unit price and the product name. The registration process of the single item for the product code thus input ends.

Further, in the conventional device, if there is no product code inquired in the search of the PLU file by the file controller, the fact is notified to the cash register, and the error is notified in the cash register upon receiving this notification.

[Problems to be solved by the invention] By the way, since the work of reading a product code from a product with a bar code scanner is continuously performed, the product codes are sequentially displayed even while inquiring a certain product code to the file controller. Will be entered. There is a problem that even if an error occurs due to an inquiry in the middle of such work and the error is notified, the operator cannot know which product the error is, which causes a great obstacle to the registration work.

The present invention has been made to solve such a problem, and it is possible to grasp which product code is an error when making an inquiry on the terminal side. It is a more reliable grasp.

In addition, the present invention improves the usability by performing the operation of canceling the inquiry error in two ways.

[Means for Solving Problems] The present invention relates to a file controller provided with a product information file in which product information such as a unit price is set for each product code attached to each product, a product code input means, and a display device. When a product code is input from the input means of the terminal, the file controller inquires about the product code, and the file controller displays the product information corresponding to the inquired product code. In the product sales data processing device that reads out the product information file and sends it to the terminal, the terminal receives the product information from the file controller, displays it on the display, and registers the product sales data. If there is an inquiry, the corresponding product code will be the product information If there is no corresponding product code in the file, search means is provided to send a message to that effect to the terminal. When the file controller informs the terminal that there is no corresponding product code, an error message is displayed. Display processing means for displaying the inquiry code on the display, a sound generator that operates when the file controller notifies that there is no corresponding product code, a clear key, and a sound is generated by the first operation of the clear key. Clear processing means is provided for stopping the operation of the device and clearing the display of the error message and the inquiry code on the display by the second operation of the clear key.

Further, according to the present invention, the operation of the sound generation device is stopped by the first clear key operation, and the display of the error message and the inquiry code of the display device c is cleared by the second clear key operation. It is possible to select a process of simultaneously stopping the operation of the sound generator and clearing the display c by operating the clear key.

[Operation] In the present invention having such a configuration, when the product code is inquired from the terminal to the file controller and the product code is not in the product information file, the terminal operates the sound generation device to notify and display an error occurrence. The inquiry code is displayed on the display along with the error message to inform the inquiry code that resulted in the error. If the clear key is operated in this state, only the sound generator is stopped and the display on the display is left as it is. In this way, the confirmation of the inquiry product code that caused the error is made more reliable. When the clear key is operated again, the display on the display is cleared and the error is released.

Also, depending on the selection, it is possible to decide whether to stop the operation of the sound generator and clear the display of the display with two clear key operations or one clear key operation. You can

The processing shown in the figure is performed by the operation system program, and the processing shown in FIG. 7 is performed by the application program.

That is, the process of FIG. 4 is started when a system call is made by the application program, it is judged which of the key buffers 23 ₁ and 23 ₂ is selected by the program, and if the key buffer 23 ₁ is selected, reset the key take-viewed flag F ₄ to "0", and also sets the key acquisition viewed flag F ₄ if the key buffer 23 ₂ is selected to "1".

The process shown in FIG. 5 is a key interruption process. When there is a key code input from the bar code scanner 25 or the keyboard 27, the state of the key take-in flag F ₄ is checked, and F ₄
If a = 1 to set the key code to the subkey buffer 23 _2. The key code in this case is only the key code from the keyboard 27. If F ₄ = 0, the key code is set in the main key buffer 23 ₁ . The key code in this case is one of the barcode scanner 25 and the keyboard 27.

FIG. 6 shows a key take-in process. In this process, the state of the key take-in flag F ₄ is first checked, and if F ₄ = 1 it is checked whether or not there is a key code in the sub key buffer 23 _2. to lead the key code of the subkey buffer 23 _2, and ends the process passes the key code to the application of the process. The subkey buffer 23 ₂
If there is no key code in, this process ends immediately.

When the key take-in flag F ₄ is checked, F ₄ = 0
If so, it is checked whether or not there is a key code in the main key buffer 23 ₁ , and if there is, the main key buffer 2
3 in ₁ to lead the key code, the process is terminated by passing the key code to the application of the process. Also this process immediately ends if there is no key code on a main key buffer 23 _1.

The key code processing Figure 7 is passed from the operation program checks whether the key code of the clear key 27 _4, in the error continues unless a key code of the clear key, i.e. the error flag F ₁ is set Check whether or not. If the error flag F ₁ = 1 then the key code is discarded and the error state is retained.
If F ₁ = 0, the key code is checked as registration data. If it is the PLU code, the file controller 11 is inquired. As a result, if no error occurs, registration processing is performed. In this registration process, the unit price, department code and product name based on the PLU code inquiry from the file controller 11 are received, the unit price and department code are displayed on the display unit 29, and the unit price, department code and product name are printed by the printer 31. Output. Further, the section-by-section total is registered in the RAM 23. When this process ends, the program is returned to the operation program.

Further, if an error occurs in the registration data check, it is checked whether or not the error is caused by an inquiry to the file controller 11, and if it is not an error due to the inquiry, the display 29 shows (a) of FIG. ), Only the error message is displayed, the key buffer is switched to the sub key buffer 23 ₂ , and the key buffer change flag F ₂ and the error flag F ₁ are displayed.
And the buzzer 35 and the error lamp 29 ₁ are turned on. If the error is due to an inquiry, an error message and an inquiry code as shown in FIG. 10 (b) are displayed on the display 29 (display processing means) and the printer 31 prints them out. (Print Processing Means) Further, the key buffer is switched to the sub-key buffer 23 ₂ to change the key buffer change flag F ₂ and the error flag F.
₁ is set (product code saving means), and the buzzer 35 and the error lamp 29 ₁ are turned on.

After this processing, the clear key has a double-operation specification, so it is judged whether it has a single-operation specification, for example, by the state of the DIP switch for setting (selection means of clear processing means), double-operation specification. if made to set the clear key waiting flag F ₃ to "1" to return to the operation program. If it is a one-time operation specification, it returns to the operation program as it is.

The key code passed from the operation program in error followed if the key code of the clear key 27 _4, i.e. checks whether an error flag F ₁ is set. If F ₁ = 0, normal clear key processing is performed. If F ₁ = 1 then the state of the key buffer change flag F ₂ is checked and F ₂
If = 0, normal clear key processing is performed. Also F ₂
If = 1, the state of the clear key wait flag F ₃ is further checked. If F ₃ = 1 then only the buzzer 35 is turned off and the operation program is returned. If F ₃ = 0, the error flag F ₁ and the key buffer change flag F ₂ are reset to “0” respectively, and if the buzzer 35 is ON, both the buzzer 35 and the error lamp 29 ₁ are turned OFF, and the key is pressed. return the buffer to the main key buffer 23 ₁ to return to the system call and operation program. (Clear Processing Means) The CPU 13 of the file controller 11 controls each ECR.
When the PLU code is inquired from 12 _{1 to} 12 _{n, the} processing shown in FIG. 8 is performed. That is, PLU file 1
6 is checked to see if the same PLU code as the inquiry code is set. Then, if there is, the unit price, department code and product name corresponding to the PLU code are edited as a response message and transmitted to the inquired ECR. The PLU code of the inquiry is PLU file 1
If it is not 6, the inquiry code is stored in the RAM 15 as an inquiry error code (error code storage processing means), and a negative response message notifying that there is no PLU code is edited and transmitted to the ECR inquired. To do. This processing constitutes search means.

In addition, the CPU 13 of the file controller 11 causes the ninth
The print process shown in the figure is performed. That is, when the inquiry code print command is input, the inquiry error codes stored in the RAM 15 are sequentially printed out by the printer 18 and a report is issued.

In this embodiment having such a configuration, each ECR 12 ₁
When the PLU code is input from the bar code scanner 25 or the keyboard 27 in one of the .about.12 _n , the PLU code is sequentially loaded into the main key buffer 23 ₁ and set in the PLU file 16 in the order of loading. The file controller 11 is inquired whether or not it is present. If the PLU code is set in the PLU file 16, the unit price, department code and product name are sent from the file controller 11, and the ECR displays the unit price and department code on the display unit 29 and the unit price, department code and product name. Is printed out by the printer 31. Also, the department is registered in the RAM 23 based on the department code.

If the PLU code inquired is not set in the PLU file 16, a negative response is received from the file controller 11 and the display 29 inquires of the message "UND (UNDEDEFINE)" as shown in FIG. The PLU code “490135103501” is displayed. Further, the content is printed out by the printer 31 and recorded. Further, the key buffer used for fetching the key code is switched from the main key buffer 23 ₁ to the sub key buffer 23 ₂ , and the error flag F ₁ and the key buffer change flag F ₂ are set. Further, the buzzer 35 and the error lamp 29 ₁ are turned on. In this way, the operator knows as a result of the inquiry that there is no corresponding PLU code and an error has occurred. Then, the display unit 29 can surely know which PLU code corresponds to it. Therefore, even when the PLU code is continuously input by the barcode scanner 25, for example, which PLU code has an error can be known. Further, since the PLU code having the inquiry error is printed and recorded, it can be confirmed later. The buffer 23 Furthermore, since the main key buffer 23 ₁ leaves off
_The other key codes stored in ₁ are saved without being cleared.

In the file controller 11, the PLU file 16
When the PLU code corresponding to is not set, the code is stored in the RAM 15 as an inquiry error code.

If ECR For example, in the clear key twice specifications that are configured operator only the buzzer 35 is turned OFF at the time of operating the first clear key 27 _4, the display is maintained. Therefore, since even if the operation immediately clear key 27 ₄ forgot to confirm the code noticed an error in the sound of the buzzer 35 display has become To it can be confirmed then PLU code error. P that made an error like this
Confirmation of the LU code becomes more reliable.

The display cleared, also switched even key buffer for taking the key code from the subkey buffer 23 ₂ on a main key buffer 23 ₁ by performing a second clear key 27 ₄ operation. Thus, the main key buffer 23
_The other key code saved in ₁ is sequentially read by the operation program to make an inquiry to the file controller 11, and the file controller 11 is registered in the PLU file 16.

Therefore, PLU code of the taken even query error occurs in the middle of crowded taken in succession the PLU code to the main key buffer 23 ₁ are all valid, moreover that after the error condition has been released Since the PLU code is continuously registered, there is no trouble of re-inputting the PLU code after the PLU code having the inquiry error.

Furthermore, in the file controller 11, RAM1
The PLU code with the inquiry error is stored in 5.
Since the printer 18 can print out and issue a report later, for example, when setting the PLU code having the inquiry error in the file controller 11 in the PLU file 16, the operation becomes easy.

In addition, decide once specifications are clear key twice specification by dip switch, in the case of the two-times specification is OFF the buzzer 35 in the first round of the clear key operation by setting the clear key waiting flag F _3, 2 The error state can be released by the first clear key operation, and in the case of the one-time specification, the error can be immediately released by one clear key operation. Therefore, the method of releasing the error can be selectively used according to the application, which is convenient.

In the above embodiment, the case where the PLU code is used as the product code has been described, but the present invention is not limited to this, and may be a JAN code or an EAN code.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to easily confirm by a display which product code an error occurs when making an inquiry about which product code. In addition, the product code that caused the inquiry error is displayed at the terminal, and a sound is generated. Only the first clear key operation stops the sound, and the second clear key operation erases the product code display. Therefore, it is possible to provide a product sales data processing device which makes it possible to more reliably grasp the product code in which the inquiry error occurs.

Further, according to the present invention, the operation for canceling the inquiry error is 1
It is possible to provide a product sales data processing device that can be used according to the purpose and is convenient because it can be selected from two methods, one with the clear key operation once and the other with the clear key operation twice. Is.
