DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a data processing device d, such as an electronic register, comprising a barcode league for electro-optically reading a barcode.

[Prior art and points of interest]

When the number of products increases at Kugigo, Ichiichiko Register,
Along with this, the number of keys for registering products will increase,
The keyboard becomes larger. For this reason, it was impossible to use the so-called book-type input pull in which two sheets of function display paper were twisted together.Also,
Generally, it is difficult to add more than a predetermined number of keys on a computer because space is limited.

[Purpose of the invention]

This invention was made based on the above-mentioned small h1, and its purpose is to perform data processing that enables data input using a new method without increasing the number of keys or increasing the size of the keyboard. The goal is to provide equipment.

[Key points of the invention]

In order to achieve the above-mentioned purpose, this invention displays a barcode based on a barcode pattern stored in advance, irradiates the displayed barcode with light, and emits the reflected light. The gist of this is that the barcode is read by converting 'J:...' into a signal.

[Example]' Hereinafter, the present invention will be specifically explained based on an example of Mr. Ichiten shown in the drawings. FIG. 1 is a block circuit diagram of an electronic register to which the present invention is applied. Reference numeral 1 in the figure shows a keyboard, in addition to keys 1b for functions 1 to 1 ask 7, mode changeover switch 1'', department keys, transaction keys, etc., there is also a liquid crystal display panel 2 formed in a horizontally long strip shape, and a liquid crystal display panel 2. A page switching key 1d is provided for switching the display contents of the panel 2.

irj L, key manual data output from keyboard 1 corresponding to operation keys and mode changeover switch I
Mode designation data outputted to each switching position of C is input to a CPU (central processing circuit) 3.

In addition, in the electronic register in this embodiment, light is shined on a medium such as a label on which a black and white barcode is recorded = -7
A hand scanner type (1) capable of manual scanning that converts the difference in reflectance into a blood signal and reads the barcode optically.
fj has been obtained. The data read by this barcode reader 4 is input to the edict 1Iili circuit 5, and the WB
Nl:3: It is pitched to the code and input to 0PU3.

In this embodiment, the barcode reader 4 can read barcodes based on the JAN code system.

The CPU 3 controls various operations according to pre-stored micro-instructions and executes input processing, bell-climbing processing, etc. according to the outputs of the keyboard 1 and barcode reader 4, and predetermined address data is stored in the CPU 3. (7) X, Y, ztz [digit code with star].

It is. .

The classification memory 6, the total memory 7, and the conversion table memory 8 are constituted by RAM (random access memory), and write and read operations are controlled under the control of the CPU 3. The classification memory 6 is a character that indicates the product name for each product! It stores lid data, barcode data consisting of a combination of decimal numbers, unit price, and total sales quantity. 6) As shown in Figure 2, n products are stored in one
In the case of a page, data corresponding to N pages of products are stored. Further, the total memory 7 stores total sales data by department and transaction. Further, the conversion table memory 8 stores barcode patterns corresponding to the barcode data in the classification memory 6. That is, as shown in FIG. 3, the light bar,
Binary barcode patterns corresponding to barcode data of the left bar, center bar, and characters 0 to 9 are stored. In this case, in this embodiment, since the JAN code is read and processed as the code system, the barcode pattern shown in FIG. 3 corresponds to the JAN code. In other words, binary 0'' is a white bar, 1''
corresponds to a black bar, and the thickness of the bar varies depending on the number of times the same data is repeated. In addition, JANJ-do generally has a barcode of 4 to 6 characters on both sides of the center bar, and a light / barcode on the right end.
' % Left end L LL It has a left bar, and there are 3 each of left and right bars, 5 seven-bars,
The character bar or character bar is ti'fed with a total of 4 bars, 2 white bars and 2 black bars. As a result, the above-mentioned barcode pattern is also constructed based on the above-mentioned JAN Food rules.

On the other hand, the barcode pattern read from the conversion table memory 8 is read into the buffer memory 9 via the CPU 3. The buffer memory 9 stores a barcode pattern corresponding to one page of the classified memory 6 together with the corresponding character data read from the classified memory 6. On the other hand, the bar code pattern and character data temporarily stored in the buffer memory 9 are supplied to the liquid crystal display panel 2 via the liquid crystal drive circuit 10.

Here, the configuration of the liquid crystal display panel 2 will be explained. The liquid crystal display panel 2 has a barcode display section 2a in its upper part that displays a product code as a black and white barcode, and a barcode display part 2a in its lower part. It is configured to include a character display section 2b that displays product names in a matrix. The barcode display section 2a and the character display section 2b are arranged with multiple digits (5 digits on the main side) in the horizontal direction, and all the digits correspond to one page of the classification memory 6. Each time the page switching key ld is operated, the display contents of all digits on the liquid crystal display panel 2 are switched to the display contents of the next page. Also, a barcode display section 2aLt, as shown in FIG. 4, is a left bar display area LB composed of three bars corresponding to the JAN code system.

Next, with 7 bars'! Y17 Character bar display area CB... Center bar display area (not shown)... Light bar display area (not shown).

In addition, the Kinfu f data etc. output from OB'U'3 are as follows:
The first part is sent to the printing unit 11 and printed on receipt paper and journal paper. At the same time, it is sent to the display section 12 and displayed digitally.

Next, the operation of the above embodiment will be explained with reference to the flowchart shown in FIG. When the page refresher 4'-1d is operated, the operation desired in the 51st flow is executed. First, in step SI, barcode data is read out from the address area of each row address area of the classification memory 6, which corresponds to the contents of the C register. In response to this read barcode data, in the next step S2, the conversion table memory 8 is searched and the process of matching the corresponding barcode pattern is completed. Zunawaji, first, the left bar, then the character bar for 1 to 6 characters, the center bar, then the 4
The character bar for ~6 characters is converted into a barcode pattern corresponding to the light bar after the crisis. The barcode pattern obtained in this way is used in the next step S.
3, the data are sequentially set in the buffer memory 9.

Next, the process goes to step S4 in line 111, and the classification memory 67.
6:+-,-5,□f-pka' i,)h (J,'
r, □, i1, +i, yo 1 is set in the buffer memory 9 by executing step S5.

When "11" 11 is completed, the next step S6
After executing the process of incrementing the contents of the C register by 1 and updating the address, the process advances to step S7, and step 4 is executed.
! A judgment is made as to whether barcode data and character bark have been read out from the separate memory 6 for one page, that is, from n address areas, and if it is 100, then
The process returns to step SI, and the same process as above is repeated. As a result, data for one page is set in the buffer memory 9.

In this way, the data for one page is transferred to the buffer memory 9, and the contents are sent to the liquid crystal display panel 2, and as shown in FIG.
, the barcode will be displayed.

In this case, assuming that the product name to be registered is displayed, the barcode reader 4 reads from the top of the liquid crystal display panel 2.
