Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a transaction processing device, and in particular to an electronic card that collectively corrects information regarding purchased products of a certain registered customer before performing a closing operation. Regarding the Tsushiyu Register (hereinafter referred to as ECR).

[Prior art] In an ECR, when a customer is sequentially inputting information regarding purchased products using keys, when the customer realizes that the data entered several times ago is incorrect.
It is necessary to collectively correct the data entered up to that point. An ECR having such a batch correction function is known from Japanese Patent Laid-Open No. 55-39959.

[Problems to be Solved by the Invention] However, the above-mentioned batch correction in ECR is a batch correction method in which information regarding products is sequentially stored for each product. However,
The ECR is equipped with a totalizer that cumulatively stores the total amount for each product and a multiplier that cumulatively stores the number of units sold for that product.
ECR does not have a function to collectively correct the contents of such totalizers and multipliers.

For this reason, in the past, when incorrect data was entered, a receipt was issued after a closing operation, and the receipt was kept at the store without being handed to the customer. By performing the same operation as normal registration in a different operation mode (for example, correction mode) while checking the contents, you can normalize the contents of the totalizer and multiplier built into the ECR. The information was corrected.

However, when performing such correction processing,
If you do not change the mode switch from registration mode to correction mode, the information entered for correction will be added to the totalizer and multiplier as information for registration, and the contents of the totalizer and multiplier will be confused. Resulting in. Therefore, there was a drawback that subsequent processing became extremely complicated. In addition, if you do not change the mode selector switch from correction mode to registration mode after making corrections, even if you enter the information for registration the next day, the information will not be displayed on the totalizer or multiplier. Instead of being added, they are subtracted, causing confusion in the registered information.

Therefore, the main object of the present invention is to provide an ECR that can prevent incorrect information from being registered or modified due to incorrect operation modes.

[Means for Solving the Problems] The present invention is an ECR that can collectively correct information related to purchased products of a certain registered customer. a mode switching means for switching between a correction mode and an inputting means for inputting information;
A collective cancellation command means for commanding collective cancellation;
Batch cancellation command storage means for storing a batch cancellation command in response to a command from the batch cancellation command means when switched to the correction mode; When product-related information is input, the content of the registered information storage means is corrected based on the input product-related information, and the memory of the bulk cancellation instruction is erased and corrected. and an arithmetic control means for processing an error in response to input of product-related information for registration or batch cancellation when the mode is switched to and a batch cancellation command is not stored.

[Operation] In the ECR according to the present invention, when performing batch correction, the mode switching means switches to the correction mode, and the batch cancellation command means is operated. As a result, a batch cancellation command is issued from the batch cancellation command means, and is stored in the batch cancellation command storage means. When the calculation control means detects that a batch cancellation command is stored in the batch cancellation command storage unit, the calculation control means corrects the contents of the registered information storage unit based on the information input from the input unit, and when the batch correction is completed, the batch cancellation command is stored in the batch cancellation command storage unit. Erase the memory of the cancellation command storage means. If the operator forgets to switch the mode and attempts to register information the next day while in the correction mode, the batch cancellation command will not be stored in the batch cancellation command storage means.
The arithmetic control means performs error processing, and there is no fear of changing the contents of the registered information storage means.

[Embodiment of the Invention] FIG. 1 is a schematic block diagram of an ECR according to an embodiment of the invention. First, the configuration of an embodiment of the present invention will be described with reference to FIG. The CPU 1, which serves as an arithmetic control means, receives product-related information, bulk correction commands, and tightening operation commands from the keyboard 2. In connection with the CPU 1, there are provided a display 4 for displaying input information and information after a tightening operation, and a printer 5 as a printing means for printing the information on a receipt. Also,
The memory 3 includes a totalizer, a multiplier, etc., which will be explained in detail in FIG. 3 below.

FIG. 2 shows an embodiment of the present invention applied.
It is a key arrangement diagram of the ECR keyboard. In FIG. 2, the keyboard 2 is provided with a mode changeover switch 22. As shown in FIG. This mode changeover switch 2
1 is correction mode, OFF to turn off the power
This mode is for switching between the mode, registration mode, inspection mode (X), and payment mode (Z). The batch cancellation key 22 is used to issue a batch correction command. Numerical keys 23 are used to input product unit price information and the like. The department key 24 is used to input a department code (DP1 to DP5), and the deposit/total key 25 is used to issue a tightening operation command when performing a tightening operation.

FIG. 3 is a diagram showing data stored in the memory shown in FIG. 1. In FIG. 3, the memory 3 includes an area 31 serving as registration information storage means and an area 32 necessary for arithmetic processing. Registration information storage means 3
1 includes a total key that cumulatively stores unit price information corresponding to each of department 1 (DP1) to department 5 (DP5), and a counter that stores the number of times that each department has been registered. Area 311 to 31
Contains 5.

The registration information storage means 31 includes a totalizer that stores information on the total amount of products purchased by all customers;
An area 316 is provided as a counter for storing the number of times. Furthermore, the area 32 necessary for arithmetic processing includes an area 3 as a number buffer (NBF) that temporarily stores numerical information input from the numerical keys 23.
21 and an area 322 for storing a numeric value flag (FM) indicating that the numeric key 23 has been operated.
and an area 323 for setting a batch correction declaration flag (FTV) indicating that the mode changeover switch 21 has been switched to the correction mode and the cancel key 22 has been operated, and information indicating batch correction, that is, batch correction, by the printer 5. It includes an area 324 for setting a bulk correction registration flag (FiTm) indicating that a correction mark has been printed, and an itemizer 325 for storing the total unit price information of products purchased by a certain customer.

4A and 4B are diagrams showing a key operation procedure according to an embodiment of the present invention, and FIG. 5 is a flowchart for explaining the specific operation of an embodiment of the present invention.

Next, with reference to FIGS. 1 to 5, a specific operation of an embodiment of the present invention will be described.

First, referring to FIG. 4A, the operator switches the mode changeover switch 21 to the registration mode. Thereafter, in order to register, for example, a product with a unit price of 100 yen and in department 1, numerical information "100" is input using the numerical keys 23.

The CPU 2 constantly determines whether there is a key input signal from the keyboard 2, and if there is a key input, determines whether the key input is a key input signal from the cancel key 22. If it is not a key input signal from the cancel key 22, it is determined whether it is a key input signal from the numeric key 23 or not. Numeric key 23
If it is a key input from , the input numerical information "100" is stored in the numeric buffer (MBF) 321 and the numeric flag (FM) 322 is set.

Next, the operator enters the department code (DP1) of the product by pressing DP1 of the department key 24.
Operate the keys. When the CPU 1 determines that the department key 24 has been operated, the CPU 1 switches the mode changeover switch 2.
1 is switched to correction mode or registration mode. If it is switched to registration mode, batch correction declaration flag (FTV) 32
3 is set.

Since it is impossible for the cancellation key 22 to be operated in the registration mode, if the batch correction declaration flag 323
If is set, error handling will occur. Further, it is determined whether or not the number flag 322 is set, and if it is set, the input department code and unit price information are printed as registered details on the receipt by the printer 5. Furthermore, the unit price amount information stored in the number buffer 321 is cumulatively added to the totalizer in the area 311 corresponding to department code 1. At the same time, the multiplier 311 is set to +1. Then, the unit price amount information of the number buffer 321 is added to the itemizer 325, and the number flag 3 is added to the itemizer 325.
22 to return to the initial state.

The above operations are repeated to repeatedly register information on products purchased by the customer. Finally, the deposit/total key 25 is operated to perform the tightening operation. When the CPU 1 determines that the deposit/account key 25 has been operated, it determines whether the mode changeover switch 21 is switched to the correction mode or the registration mode. If it is in the registration mode, the batch correction flag 323 and the number flag 32
2 is not set. Then, the printer 5 prints the total amount of the purchased products of the customer cumulatively stored in the itemizer 325 on the receipt. Furthermore, the itemizer 32
The total amount information stored in 5 is cumulatively stored in the totalizer in area 316. Furthermore, since the registration process for that customer has been completed, the itemizer 325 is cleared and a receipt is issued from the printer 5 in order to enable the registration of the next customer.

Next, assume that the user makes a mistake in operating the keyboard 2 when inputting information regarding a product purchased by a certain customer. In this case, the erroneous information is stored in the registration information storage means 31 and the erroneous information is printed on the receipt. This receipt is stored as an erroneously entered receipt, and the operator inputs the correct information from the keyboard 2. After the business is closed, the operator performs correction processing.

That is, the operator switches the mode changeover switch 21 to the correction mode and operates the cancel key 22, as shown in FIG. 4B. When the CPU 1 determines that the cancel key 22 has been operated and the mode has been switched to the correction mode, the CPU 1 determines whether or not the number flag 322 is set. If it has not been set, the CPU lights up a batch correction declaration display lamp (not shown) to indicate batch correction.
A batch correction declaration flag (FTV) 323 is set.

Next, the operator sequentially inputs information based on the contents printed on the misprinted receipt. That is, numerical information "100" is input using the numerical key 23. Then, the numerical information is stored in the numeric buffer 321 and the numeric flag 322 is set in the same manner as described above. Furthermore, when department code 1 is input from the department key 24, the CPU
1 determines that the department key 24 has been operated and is in the correction mode.

Furthermore, when it is determined that the batch correction declaration flag 323 and the number flag 322 are set, it is determined whether the batch correction registration flag (FiTm) 324 is set. At this point, since the batch correction registration flag 324 has not been set, the batch correction mark is printed on the receipt by the printer 5. Then, to indicate that the batch correction mark has been printed, a batch correction registration flag 324 is set, and the input unit price amount information and department code are printed on the printer 5. Furthermore, area 3 corresponding to the entered department code 1
The contents of the totalizer No. 11 are corrected based on the contents of the numeric buffer 321. At the same time, the multiplier 322 is set to -
Do 1. Further, the contents of the numeric buffer 321 are accumulated in the itemizer 325, and the numeric flag 322 is reset.

When the operator sequentially enters the information printed on the misprinted receipt using the keys, the CPU 1 repeats the above-described operation. Thereby, the erroneous information stored in areas 311-315 is corrected. After inputting all the information, the deposit/total key 25 is operated. When the CPU 1 determines that the deposit/current total key 25 has been operated and is in the correction mode, it determines that the batch correction declaration flag 323 is set and the number flag 322 is not set. Then, the total amount of all the erroneous information stored in the itemizer 325 is printed on the receipt by the printer 5.

Furthermore, based on the contents of the itemizer 325, the total amount in the area 326 is corrected and the multiplier is decremented by 1. Furthermore, since all correction processing has been completed, the itemizer 325 is cleared, and the batch correction flag 323 and one-time correction registration flag 324 are cleared.
Clear. Finally, a bulk correction receipt is issued.

[Effects of the Invention] As described above, according to the present invention, only when the correction mode is switched to and the batch cancellation command is stored, when information related to the product is input, the registered information storage means We have corrected the contents of , and if the bulk cancellation command is not stored even if the mode is switched to correction mode, an error will be handled even if information related to the product is entered for registration or bulk cancellation. It is possible to prevent confusion in registered information due to an error in switching the operation mode, such as performing an erroneous correction process in the correction mode or performing an erroneous registration process in the correction mode.
