Description

Description: TECHNICAL FIELD The present invention relates to a POS terminal device capable of reading a multi-stage code, and more particularly to a POS terminal device that correctly obtains a multi-stage code of one product as a set of data.

[Conventional technology]

In the conventional technology, an OCR that can read a multi-stage code (also called a long code, which is a product code composed of multiple blocks)
In the reading POS terminal device, the latest version POS system 100 questions 1
00 Answer As shown in PP149-152, the input data can be identified by C, N, and ¥ in the first digit, so the reading order of these information can be any order. Even in the code, the code was assigned so that the data could be distinguished by the identifier of the head. For this reason, the input order may be any order.

[Problems to be Solved by the Invention]

In the above-mentioned conventional technology, there is a case in which the data of the product B different from the data of the product A is collected as the data of the product A.

In order to make the story easier to understand, a case where one item of product data is represented by a two-stage code will be described as an example.

In the order of reading the code, in the case where the upper part of the product A is read first and then the lower part of the product A is read, or the lower part of the product A is read first and then the upper part of the product A is read, the product A The upper and lower rows are combined and correctly regarded as the data of one product. However, depending on the operator's operation, the lower part of the product A may be read first without reading the upper part of the product A. If the next upper part of the product B is read after this, the lower part of the product A is mistakenly read inside the POS. In some cases, the above and the upper part of the product B are processed as a combination to represent the data of one product, and the data is acquired in an incorrect form.

An object of the present invention is to prevent erroneous combination of the data of one product in such a case where the data of one product is represented by a multi-level code, and to obtain the data by correctly combining the data of the multi-level code. To provide a device.

[Means for Solving the Problems]

The above-mentioned object has an input code management memory for identifying the column code that has been input up to that point, an input order determination unit for determining the input code and the input order of the input code, and means for issuing a warning. In the case where the codes are entered in a sequence other than the specified sequence, a warning is issued to alert the operator, whereby the POS terminal measures can be achieved by the operator reading the codes in the correct sequence.

[Action]

A step having a product code composed of multiple steps is input from the input means and the attribute of the input code is identified. This attribute,
The input order management unit determines the input order by the input code management memory set by the stage data of the product code that has been input up to this time, and if normal, inputs that the data has been input. It is set in the code management memory, and when there is an abnormality, a warning is issued to inform the operator that the input order is abnormal. Thereby, it is prevented that the data of a certain product and the data of another product are combined and acquired.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of a POS terminal device according to the present invention. 1 is an input unit, 2 is a warning unit, 3 is a control unit, 31 is an input order determination unit in the control unit 3, 4 is a storage unit, 41 is an input code management memory in the storage unit 4, and 42 is in the storage unit 4. This is the product data area. In this embodiment, the data of one product is represented by a two-stage code, which is called an upper-stage code and a lower-stage code,
421 is an upper code code area in the product data area 42, and 422 is a lower code area in the product data area 42.

FIG. 2 shows cases in which the processing in the input order determination unit 31 is possible. The upper code first input, the lower code first input, the upper code first input only, and the lower code first input are possible. The case where only pre-input is possible can be a case of mutually exchanging each other, but in the present embodiment, a process that allows only pre-input of the upper code is incorporated.

FIG. 3 shows possible values of the input code management memory 41 that manages the entered code. The value 0 is not entered for the upper and lower codes, the value 1 is entered for only the upper code, and only the lower code is entered. There are four possible values, 2 being the input value and 3 being the input value for both the upper code and the lower code, but in the present embodiment, only the upper input is allowed, so the value 2 is not possible.

FIG. 4 shows an example of the data input order. FIG. 5 is a flowchart of processing in the control unit 3 and the input order determination unit 31. Regarding the judgment of the input code in FIG. 5, the judgment of the registerable product code and the judgment of the upper code and the lower code are made according to the registerable product code table 43 shown in FIG. 6 and the flowchart of FIG. The record in the registerable product code table 43 is used to compare the number of digits of the input code with the first two digits (S11). If they match, it is determined whether the record is the upper row code (S12). If the upper row code, the upper row A value indicating the code is set (S14), and if it is not the upper code, it is determined whether the record is the lower code (S1
3) If it is a lower code, a value indicating the lower code is set (S15), and if it is not the lower code, a value as an unused code is set (S16). Further, in S11, even when there is no same record, a value as an unused record is set (S16), and thus the input code determination S1 is possible.

Hereinafter, description will be made in the order of data input in FIG.

When the upper code of the product A is input from the input unit 1 in the initialized state, the input order determination unit 31 on the control unit 3 determines that the input code is the upper code (S1), and the input code management memory 41 0 (S2) Product data area
42 and the input code management memory 41 are initialized, and the input code management memory 41 becomes 0 (S3). Subsequently, the value 1 indicating the upper code input is set in the input code management memory 41, and the input data is set in the upper code area 421 (S4).

Next, when the lower code of the product A is input from the input unit 1, the input order determination unit 31 on the control unit 3 determines that it is the lower data (S1), and further, the value of the input code management memory 41. Is determined to be 1 (S5), and as normal processing,
The upper code and the lower code are both set to the value 3 which has already been input to the input code management memory 41, and the input data is set to the lower code area 422 (S7), and the data in the product data area 42 is displayed (not shown). The data in the product data area 42 is saved in a product data save area (not shown) (S9).

Next, when the upper code of the product B is input from the input unit 1, the input order determination unit 31 on the control unit 3 determines that it is the upper code (S1), and then the input code management memory 41.
Since the upper code and the lower code have already been entered, the upper code of the next product can be entered (S2), the product data area 42 and the input code management memory 41 are initialized, and the input code management memory 41 is 0. (S3). Further, the value 1 indicating the upper code input is set in the input code management memory 41, and the input data is set in the upper code area 421 (S4).

Next, when the upper code of the product C is input from the input unit 1, the input order determination unit 31 on the control unit 3 determines that the input code is the upper code (S1), and further, the input management memory 41 Is not 0 or 3, it is judged as an error instead of a code waiting for input (S2), an alarm sound of error is emitted from the warning unit 2 (S6), and correct input is waited.

Next, when the lower code of the product B is input from the input unit 1, the input order determination unit 31 on the control unit 3 determines that the input code is the lower code (S1), and then the input code management memory. It is determined that the value of 41 is 1 (S5), and as a normal process, the input code management memory 41 is set to the value 3 for which both the upper code and the lower code have been input, and the input data is input to the lower code area 422. Set (S
7), the data in the product data area 42 is displayed and printed (S8) on a display unit and a printing unit not shown, and the product data area 42 is displayed.
The data of 42 is saved in a product data save area (not shown) (S9).

Next, when the lower code of the product D is input from the input unit 1, the input order determination unit 31 on the control unit 3 determines that the input code is the lower code (S1). It is determined that the value of 42 is 3 and is not 1 (S5), the warning unit 2 issues a warning sound of an error that the code is not a code that can be input as the input sequence (S6), and waits for correct input.

Next, when the upper code of the product E is input from the input unit 1, the input order determination unit 31 on the control unit 3 determines that it is the upper code (S1), and further, the input code management memory 41.
However, since the upper code and the lower code have already been entered, the input of the upper code of the next product is OK (S2), the product data area 42 and the input code management memory 41 are initialized, and the input code management memory 41 Becomes 0 (S3). Subsequently, the value 1 indicating the upper code input is set in the input code management memory 41, and the input data is set in the upper code area 421 (S4).

As described above, according to the present invention, it is possible to prevent the lower code of the product D and the upper code of the product E from being processed as the data of one product, and the data of one product is correctly acquired as the data of one product. To be done.
