Abstract

PURPOSE:To unify a key and a bar dedicated different input arithmetic devices by providing the data input device of a POS system with a conversion table which converts data read by a bar-code reader into key-code data. CONSTITUTION:The code read by the bar-code reader 3 is inputted to a CPU2 through an A/D conversion part 4. The CPU is provided with a key-code buffer KB stored with data from a key input part 1 and a bar-code buffer BB stored with said bar-code data. The CPU inputs and processes the key-code data directly and converts the bar-code data into a key code by using a conversion table memory 5 for input processing. Different code processing means, i.e. dedicated processors are reguired formally because of considerable difference in code system between keys and bars, but unnecessary in this case.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a data processing device that inputs and processes key code data specified by key operations on a key input section. The present invention relates to a data input method that also inputs and processes data that has been input.

[Prior art]

Recently, as a data input means for POS systems such as electronic registers, media on which various types of information are recorded in black and white barcodes are irradiated with light and the differences in light reflectance are converted into electrical signals. Optical barcode reading devices that read barcode information have been put into practical use. As this type of reading device, pen-type hand scanners (barcode readers) capable of manual scanning are widely used. The electronic register equipped with this pen-type hand scanner is configured to be able to input barcode data, keycode data, and other input data through key operations on the key input section. That is, at the same time as the power is turned on, operations are executed according to the flowchart shown in FIG.

That is, first, in step S_1, it is checked whether or not key code data has been input. If it is determined that key code data has been input, the process proceeds to step S_2, and key code input processing based on the input key code data is executed. . Further, if it is determined that the step S_1 is negative, the process proceeds to step T_3, where it is checked whether barcode data has been input using a pen-type hand scanner. In this case, if no barcode data is input, step S_1
However, if barcode data is input, the process proceeds to step S_4, and barcode input processing is executed based on the code system of the barcode data read by the pen-type hand scanner.

[Problems with conventional technology]

Conventionally, key codes and bar codes have very different code systems, so code data from a keyboard and code data from a pen-type hand scanner are input based on separate code processing procedures. Was. Therefore, in order to be able to input data from a pen-type hand scanner, it was necessary to provide an input arithmetic processing device exclusively for barcode data in addition to the key input arithmetic processing device.

[Purpose of the invention]

The present invention was made against the background of the above-mentioned circumstances, and its purpose is to eliminate the need for providing an input arithmetic processing device exclusively for data read by input means other than the keys of the key input section.
The object of the present invention is to provide a data input method that enables input processing of the data.

[Key points of the invention]

In order to achieve the above-mentioned object, the present invention provides an electronic arithmetic processing device in which key code data is input by key operations on a key input section, in which data read by an input means other than the keys of the key input section is input into the key code data. The gist is that the data is converted into data and input to the arithmetic processing device.

〔Example〕

Hereinafter, this invention will be specifically explained based on an embodiment shown in FIGS. 2 to 6. FIG. 2 is a schematic system configuration diagram of an electronic cash register to which the present invention is applied.
This is a key input unit equipped with an LU key (product-specific registration key), a subtotal key, a clear key, etc. This key input section 1
The key code data outputted from the CPU 2 corresponding to the operation keys is inputted to a CPU (central processing unit) 2.

On the other hand, 3 in the figure is a pen-type hand scanner type barcode reader, and the barcode information read by this barcode reader 3 is converted into a digital signal by an A/D (analog/digital) converter 4 and sent to the CPU 2. is input.

The CPU 2 controls various operations, and includes a key code buffer KB that stores key code data from the key input section 1 and bar code data input from the bar code reader 3 via the A/D conversion section 4. The configuration includes a barcode buffer BB that stores . Therefore, CP
For U2, if the input data is key code data,
In the case of direct barcode data, input processing is executed after converting it to keycode data. In this case, conversion from a barcode to a keycode is executed by exchanging data with the conversion table memory 5. Note that the CPU 2 outputs display data or print data to the display section 6 and the printing section 7, and
Data is exchanged with the total memory 8 to accumulate total sales data.

Further, FIG. 3(A) shows a barcode data list notebook used in ordinary shops, etc., and barcode data corresponding to various keys provided in the key input section 1 are printed on this list notebook. When registering a product, the operator performs key operations in the key input section 1.
By operating the pen-type hand scanner, it is possible to input various data. In addition, Figure 3 (B) shows a menu board for each clerk used in restaurants, etc., and this menu board shows each clerk's own clerk number, the price of each menu, and the subtotal. Data corresponding to each transaction key is printed as barcode data.

The table below shows the correspondence between key codes and bar codes associated with various keys of the key input section 1.

Note that the conversion table memory 5 stores key code data and bar code data in a correspondence relationship based on this table.

In this way, the key code is 2 digits, and the bar code is 8 digits.
It is expressed in digits, and each has a different code system.

Therefore, the barcode buffer BB is D as shown in FIG.
It consists of 8 digits, _1 to D_8. Therefore, the upper two digits of barco buffer BB, namely D_1 and D_2
The data written to is data representing the type of code, such as "11" if it corresponds to a transaction key such as a cash/deposit key, "22" if it corresponds to a subtotal key, and PL.
"33" if it corresponds to the U key, "44" if it corresponds to the clear key, "95" if it corresponds to the numeric key
etc. are stored. Further, digit data or key number is stored in digits D_3 to D_7. In this case, the asterisk (*) is any numerical data that can be entered; if it is a barcode that corresponds to the cash/deposit key, it is the amount data; if it is a barcode that corresponds to the PLU key, it is the PLU key.
It becomes the number.

In other words, for D_3 to D_7 digits, for example, "00000" when corresponding only to the PLU key;
If the PLU number "25" corresponds to the specified PLU key, "00025", and similarly, if it only corresponds to the cash/deposit key, "00000".
”, and if the single item registration of amount data “100” corresponds to the specified cash/deposit key, it becomes “00100”.

In addition, the key numbers D_3 to D_7 are associated with key codes; for example, "00021" corresponds to the numeric key ■, and "0002" corresponds to ■.
2'', ■ corresponds to ``00023'', and so on. Further, the D_8 digit indicates a check digit (C_D).

Next, the operation of the above embodiment will be explained.

First, when the power is turned on, the operation according to the main flow shown in FIG. 5 is executed. That is, in step S_1_1, it is checked whether key code data has been input,
If it is determined that the data has been input, the process proceeds to step S_1_2 to transfer the data to the key code buffer KB, and then proceeds to step S_1_3 to transfer the data to the key code buffer KB.
Key code input processing is executed according to the contents.

Further, if it is determined no in step S_1_1, the process proceeds to step S_1_4, where it is checked whether or not barcode data has been input from the barcode reader 3, which is a pen-type hand scanner, and barcode data has also been input. If not, the process returns to step S_1_1, but if barcode data is input, the process proceeds to step S_1_5. Here, processing is executed to transfer the input barcode data to the barcode buffer BB. The barcode data transferred to the barcode buffer BB is converted into corresponding keycode data in the next step S_1_6. This step S_1_6 is the sixth step to be described later.
The conversion process is executed according to the flow shown in the figure, and the data converted to the key code is subjected to the key code input process in step S_1_3 in the same manner as described above. When the key code input process is completed in step S_1_3, the process returns to step S_1_1.

Next, the conversion process will be explained in detail according to the flow shown in FIG. First, in step S_2_1, barcode buffer B
It is checked whether the contents of digits D_1 and D_2 of B are "11", that is, barcode information corresponding to the cash/deposit key. If it is determined no, the next step S_2
Proceed to _2, and the contents of D_1 and D_2 digits are "33"
That is, it is checked whether the barcode information corresponds to the PLU key.

If it is determined no, proceed to the next step S_2_3, and D
It is checked whether the contents of _1 and D_2 digits are "22", that is, barcode data corresponding to the subtotal key. If it is determined no, proceed to the next step S_2_4,
It is checked whether the contents of digits D_1 and D_2 are "95", that is, barcode information corresponding to the numeric key.

In this way, the result of searching for the key type, e.g.
If it is determined in step S_2_1 that the barcode data corresponds to the cash/deposit key, the process proceeds to step S_2_5, where the key code "51" corresponding to the cash/deposit key is read from the conversion table memory 5; Write to key code buffer KB. Further, if it is determined in step S_2_6 that the barcode data corresponds to the PLU key, step S_2
Proceeding to _6, the key code "53" corresponding to the PLU key is read from the conversion table memory 5 and written into the key code buffer KB. If it is determined in step S_2_3 that the barcode data corresponds to the subtotal key, the process proceeds to step S_2_7, and the key code "22" corresponding to the subtotal key is retrieved from the conversion table memory 5.
is read and written to the key code buffer KB. Further, in step S_2_4, if it is determined that the barcode data corresponds to the numeric key, step S_2_4 is performed.
Proceed to _2_8. Here, since the key number of digits D_3 to D_7 of the barcode buffer BB is the same as the key code, a process of directly reading the key number from digits D_3 to D_7 is executed. The key number thus read is transferred to the key code buffer KB in the next step S_2_9.

By performing such processing, the input barcode data is converted into keycode data according to the type of key, and transferred to the keycode buffer KB.

In the case of a cash/deposit key and a PLU key, after performing the above conversion process, step S_3_0
Proceed to. Here, D_3~ of barcode buffer BB
It is checked whether the D_7 digits are all "0" or not, that is, the presence or absence of numerical data. As a result, “YES”
If it is determined that
It is determined that it is a U key, but if it is determined to be "NO", it is determined that it is barcode data with amount data or a PLU number added together with a cash/deposit key or a PLU key. Therefore, in this case, the next step S
Proceeding to _3_1, number entry processing is executed based on the numerical data stored in D_3 to D_7 digits. Note that if it is determined in step S_2_4 that the barcode data does not correspond to the numeric key, the process advances to the next step S_3_2 and other processing is executed.

In addition, although the above embodiment shows the case where it is applied to an electronic register, it may be applied to other electronic devices, and input means other than keys are not limited to a pen-type hand scanner type barcode reader. Stationary barcode reader, O
It may be a CR (optical character reader), MCR (magnetic character reader), or the like.

〔Effect of the invention〕

As described above in detail, the present invention provides a data processing device having an arithmetic processing means for executing arithmetic processing corresponding to a key code data designated by a key operation of a key input section. Since the data read by the input means is converted into key code data and then processed by the arithmetic processing means, there is no need to provide an input processing device exclusively for data read by input means other than keys. Data input processing can be performed.

As a result, electronic devices that do not have input means other than keys can be equipped with input means other than keys simply by being equipped with a data reading device and a code conversion device, making it highly versatile. becomes.
