Abstract

PURPOSE: To perform the subsequent data processing only if a reinput is performed once by controlling the processing of inputted data to be permitted according to the discrimination of the matching of the data inputted previous time and the data inputted this time, when data is reinputted. CONSTITUTION: A memory 5 includes a ROM storing the operating program of a CPU 1 and a RAM including a storage area 50, and the storage area 50 includes storage areas 51 to 53. In the storage area 51, the data inputted this time is stored, and in the storage area 52, the data inputted previous time is stored. The inputted data is inspected, the processing of inputted data is inhibited when the data is not normal, whether the data inputted this time is matched with the data inputted previous time or not is discriminated when data is reinputted, and the processing of the inputted data is permitted when the data is matched. Thus, when the data becomes an input error, an error processing is evaded when the same data is reinputted and the subsequent processing is made to be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a transaction processing device, and particularly to a transaction processing device that performs registration processing of data including check digits.

[Prior Art and Problems to be Solved by the Invention] Conventionally, transaction processing devices that perform CDV (check digit, verification) processing are known. Here, CDv processing refers to, in order to prevent data input errors, a test number is added to the required data during data input, and the test number obtained from the originally required data is input. This is a process in which the numbers are compared with the test numbers and an error is detected if they do not match. Like this 11
Figure 6 shows an example of the data obtained. In FIG. 6, the upper nine digits "12B456789" are the original data, such as the slip number, and the lower one digit "3" is the check number.

By the way, in conventional CDV processing, re-input is required any number of times until the test number matches the test number determined from the originally required data. As a result, labels, etc. on which input data is written may be damaged or damaged.
If the data cannot be read correctly, no matter how many times the data is input, an error occurs and it is impossible to proceed to the next processing step.

Therefore, the main object of the present invention is to provide a data processing device that avoids error processing and performs subsequent processing when the same data is re-input in the event of an input error. It is.

[Means for Solving the Problems] The data processing device of the present invention includes a match determination unit that determines whether the data input last time and the data input this time match when data is input again from the input unit. , and control means for controlling to permit processing of the input data in response to the coincidence of the input data being determined by the coincidence determination means.

[Operation] The data processing device according to the present invention inspects input data to determine whether it is normal or not, and if it is not normal, prohibits processing of the input data, and when the data is input again,
It is determined whether the data input this time matches the data input last time, and if they match, the processing of the input data is permitted.

[Embodiments of the Invention] In the following embodiments, an electronic cash register (hereinafter referred to as ECR) will be described as a transaction processing device, but the present invention is not limited to this, and the present invention is not limited to this. It should be pointed out in advance that the present invention can be applied to any transaction processing device.

It is a memory configuration diagram of M.

Next, the configuration of an ECR according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4.

The ECR is provided with a CPUI. The CPU has two main components: a keyboard 2. Scanner 39 Display 4
and memory 5 are connected. As shown in FIG. 3, the keyboard 2 has a mode selector switch 21 and a numeric keypad 22.
and a set key 23. The mode changeover switch 21 is used to change the operation mode to OFF, normal registration mode, and manager registration mode. The normal registration mode is selected when the store clerk performs the registration process, and the manager registration mode is selected when the store manager performs the registration process. The numeric keypad 22 is used to input product codes, slip number data, and the like. The set key 23 is operated every time a product code, slip number data, etc. are input. The scanner 3 is used to input data by reading bar codes attached to products, slips, etc. The display 4 is used to display data input from the keyboard 2 or the scanner 3, and when there is an error in the input data, to display an error message and a prompt to re-enter the data. The memory 5 includes a ROM storing a CPUI operation program based on a flowchart shown in FIG. 1, which will be explained later, and a RAM including a storage area shown in FIG. This RAM storage area 50 includes storage areas 51, 52, 53, and the like.

The storage area 51 stores the data input this time, and the storage area 52 stores the data input last time. In the storage area 53, an input flag indicating whether the input data is data input from the keyboard 2 or data input from the scanner 3 is stored.

FIG. 5 is a key sequence diagram showing input operations using a keyboard. For example, when inputting a slip number from the keyboard 2, the user operates the numeric keypad 22 to input data consisting of the slip number and inspection digits as shown in FIG. 6, and then presses the set key 23.

FIG. 1 is a flow diagram for explaining the operation of an embodiment of the present invention. Next, referring to Figures 1 to 6,
The operation of one embodiment of the present invention will be described in detail. Here, CD
An example to which V processing is applied will be explained.

(A) Operation in normal registration mode i) When inputting and re-inputting 1ll is performed by the scanner 3 In step Sl (abbreviated as Sl in the figure), the scanner 3 inputs data as shown in FIG. 6, for example. be done. The input data is stored in the storage area 51. In step S2, it is determined whether the input data is not O. If the input data is 0, error processing is performed in step 313, but if it is not 0, then in step S3, the input data is processed as slip number data based on the Hj number of the input data, etc. It is determined whether the characters are correct or not. Subsequently, step S4
Then, it is determined whether the input is from the keyboard 2 or not. Here, since the input is from scanner 3, No.
It is determined that Subsequently, in step S5, a check number is calculated based on, for example, the top nine digits of the input data for the slip number.

Subsequently, in step S6, it is determined whether the calculated test number and the test number included in the input data match. Here, if the test numbers match, the process advances to step S11; if they do not match, step S11 follows.
Proceed to step 7. In step S11, since the test using the test numbers has passed, subsequent processing is performed using the current input data as slip number data. Subsequently, step S12
Then, the data in storage area 51 and storage area 52 is cleared.

On the other hand, if it is determined in step S6 that the calculated test number and the test number included in the input data do not match, the process proceeds to step S7, where it is determined whether the manager registration mode is selected. Ru. Here, since the normal registration mode is selected, step S8
Then, the data stored in the storage area 51 is transferred to the storage area 52 and stored as the previous input data.

Next, in step S9, a message to the effect that there was an input error and to prompt re-input is displayed on display S4, and step S9
Return to 1. Then, in step S1, the scanner 3
The data is re-inputted, and the same operations as described above are performed thereafter.

That is, in step S6, unless the calculated test number and the test number included in the input data match,
Re-input continues.

11) When 1ll data is input using the scanner 3 and re-input is performed using the keyboard 2 If the data is re-inputted using the keyboard 2 in step S1 described above, through step S2 and step S3, In step S4, it is determined that the input is from the keyboard 2, so the process advances to step S10.

In step S10, it is determined whether the current input data stored in the storage area 51 matches the previous input data stored in the storage area 52.

If the input data match, the process advances to step Sll; if the input data do not match, the process advances to step S5. In step S11, the data manually input by the operator this time is regarded as the slip number, and subsequent processing is performed. On the other hand, if the previous input data and the current input data do not match, the operations from step S5 onwards are performed, and re-input continues as long as the check numbers do not match.

1ll) 1ll input and re-input is done using keyboard 2.
If data is entered for the first time using the keyboard 2 in step S1, then the keyboard 2 is inputted in step S4 through steps S2 and S3.
Since it is determined whether the input is from
Proceed to O. In step SIO, since this is the first input of this slip number, it does not match the previous input data.
Proceed to step S5. Therefore, in step S6, unless the check numbers match, data is re-inputted. The operation for re-input is the same as in case 11) above, so its explanation will be omitted.

As mentioned above, in the normal registration mode, when inputting using the scanner 3, it is necessary to re-enter the input many times.
When re-input is performed using the keyboard 2, if the re-input data matches the first input data, subsequent processing can be performed regardless of whether the test digits match.

(B) Operation in Manager Registration Mode In both cases, when data is input using the keyboard 2 and when data is input using the scanner 3, it is determined in step S7 that the mode is the manager registration mode. Therefore, the process proceeds to step Sll, and even if the check numbers do not match, the input data is regarded as the slip number and subsequent processing is performed, so there is no need to re-enter the data.

[Effects of the Invention] As described above, according to the present invention, input data is inspected to determine whether it is normal or not, and if it is not normal,
Prohibits processing of input data, and when data is re-entered, determines whether the data entered this time matches the data entered last time, and if they match, allows processing of the input data. As a result, subsequent data processing can be performed by re-inputting the data only once.
