BEST MODE FOR CARRYING OUT THE INVENTION In the present specification, a bar code is a symbol for linearly arranging bar code symbol characters to be an information, which is called a one-dimensional bar code (or linear bar code). More precisely, the information is a symbol coded by an array of parallel and rectangular bars and spaces of varying width. There are also two-dimensional barcodes arranged vertically and horizontally (in a matrix) on a two-dimensional plane. By using this two-dimensional barcode, it is possible to secure a larger amount of information than the one-dimensional barcode.

In the present specification, "the first distinguishability and
The expression "the second distinguishability different from the first distinguishability" means, for example, rectangular data having the first distinguishability and rectangular data having the second distinguishability, or their This means that the stacked bars can be identified by optical means including, for example, a light receiving element and a CCD sensor.

The rectangular data is data for displaying a shape such that a bar can be formed by stacking them, and the displayed data does not necessarily have to be a complete rectangle. For example, the bar can be formed even when the data having a shape close to a circle is partially overlapped and stacked. Such data is also included in the category of rectangular data.

The case of displaying the first and second rectangular data will be described as an example, but it is also possible to display rectangular data having distinctiveness from the first to the n-th (n is an integer of 2 or more). Is.

Is operated on the display screen, a large number of data input areas defined by a substantially rectangular area, for example, a square (a cell area for inputting numerical values in spreadsheet software, one character or one in word processing software). The data input area in which one symbol can be input is referred to as a "data input area.") Is arranged on the display screen in a matrix.

When these data input areas are identified by, for example, a bar code reader, the first rectangular data having the first distinguishability, for example, a white square (□).
Symbol) and second rectangular data having a second distinguishability different from the first distinguishability, for example, a black square (sign ■) is input by operating the second software. Then, I realized that it was possible to easily create a so-called barcode pattern in which barcode symbol characters were displayed at desired intervals.

If such an application program (macro) executed by the second software is run on an application program (spreadsheet, word processor, etc.) executed by the first software, complicated image processing, etc. You can easily create a barcode (pattern) without using.

According to the barcode creating technique according to the third embodiment of the present invention, the barcode can be easily created by adding a few macros to the software for the word processor most commonly used on the PC. Can be created.

Next, referring to FIGS. 10A and 10B, a bar code creating technique according to a modification of the third embodiment of the present invention will be described.
A brief explanation will be given with reference to. The barcode creation technique according to the present modification is a technique for creating a two-dimensional barcode and is an application example of the technique according to the third embodiment.

The preparation procedure is the same as the procedure shown in FIG. 8, but in the third embodiment, only either (1) 71a or (7) 1b is arranged in the column direction, whereas in this modified example, also in the column direction. They differ in that they include a procedure for arranging different data. That is, each of the binary data is assigned on the (x, y) coordinates. More specifically, the number of columns in which continuous binary data columns are defined in advance (in FIG. 10A, 12 from the first column 83-1 to the 12th column 83-12)
You can specify it in the macro so that it will be a line break in (column). In this way, the data input areas arranged in the column direction (for example, the rows 81-1 to 81-12) and the row direction (for example, the columns 83-1 to 83-12) on the two-dimensional plane. , A symbol 81a of □ and a symbol 81b of ■ are used by using a word processor and a macro for creating a barcode.
You can enter and.

FIG. 10 (B) is a diagram showing an example in which the display shown in FIG. 10 (A) is displayed with the intervals between the respective data narrowed in the row and column directions. As shown in FIG. 10B, an arbitrary two-dimensional bar code pattern of, for example, 12 rows and 12 columns can be created simply by adding a simple macro to the word processor. By printing this two-dimensional barcode pattern with a printer or the like, a two-dimensional barcode can be easily created.

A two-dimensional bar code pattern may be created by assigning predetermined data to each cell from the initial screen of the spreadsheet software shown in the first embodiment.

As described above, when the barcode creating technique according to the first embodiment of the present invention is used, one-dimensional or two-dimensional data can be obtained by adding a simple macro to commonly used word processor or spreadsheet software. Dimensional barcodes can be created with low cost and workload. That is, it is possible to easily create a barcode without using the dedicated software for creating a barcode as in the past.

Next, a bar code creating technique according to the second embodiment of the present invention will be described with reference to FIG.
FIG. 11A is a diagram in which a part of the barcode is displayed on the mobile terminal. 11 (B) and 11 (C) are diagrams showing the work of reading the barcode displayed on the display screen of the mobile terminal using the barcode reader.

As shown in FIG. 11A, a portable terminal (cellular phone) 90 according to the present embodiment has a display screen (liquid crystal display device) 91 and power on / off buttons 92a / 92b.
It has a character / symbol input button 93, an antenna 94, and a scroll button 95 capable of scrolling the display screen.

For example, at least part P1 of the bar code pattern can be displayed on the display screen 91 by inputting and displaying □ and □ on the mobile phone 90 using the input button 93. Since the display screen of the mobile phone 90 is small, the part other than the part P1 of the barcode pattern is often hidden above or below the display screen 91.

As shown in FIG. 11B, the mobile phone 90
It is possible to directly read (a part of) the bar code pattern P1 displayed on the display screen 91 of FIG. The barcode pattern is displayed using the mobile phone 90, and the barcode pattern is displayed.
If it can be directly read by the line sensor unit (103), it can be used as an identification mark (ID) for personal identification or for admission at events or confirmation of product purchase, which is convenient.

At this time, even when it is difficult to display all the bar code patterns in the reading direction due to the limitation of the size of the display screen, the pattern on the display screen 91 is scrolled by the scroll button 95 from the state shown in FIG. 11B. All the barcode patterns (for example, P1 + P2) can be read by the barcode reader 101 by scrolling and displaying the hidden barcode pattern P2.

In this case, the bar code reader 10
It is also possible to read the bar code pattern by moving 1. However, the relative position between the bar code reader 101 and the mobile phone 90 is fixed, and the scroll button 9
It is also possible to read the bar code by scrolling the bar code pattern displayed on the display screen 91 of the mobile phone 90 in the reading direction by using 5.

Even if all the above operations are not performed on the mobile phone 90, for example, a binary data string for creating a bar code pattern is created by, for example, a PC or the like, and the data is wirelessly transmitted to the mobile phone or It can also be sent by wire. In this case, the mobile phone need only have the function of creating a barcode pattern based on the received binary data string. Alternatively, it is also possible to create a barcode pattern in a mobile phone, transfer the data to the mobile phone, and then adjust the size and print. If a printer having a wireless data reception function is used, it is possible to directly transmit data from a mobile phone to the printer and print it. Further, if a function of enlarging or reducing the display is added to the mobile phone, it is possible to easily create a pattern conforming to the bar code standard. Further, in the case of a simple barcode such as a simple JIS, it is possible to read without scrolling.

The mobile terminal in this specification means a mobile phone or a PDA (Personal Digital As).
It is a broad concept including not only a digital camera but also an electronic device having a communication function such as a digital camera.

As described above, according to the barcode creating technique according to the second embodiment of the present invention, it is possible to easily create a barcode pattern even in a mobile terminal such as a mobile phone.

Although the present invention has been described with reference to the embodiments, the present invention is not limited to these. It will be apparent to those skilled in the art that other various modifications, improvements, and combinations can be made.

[0058]

By using the bar code creating technique of the present invention, a simple macro can be added to a one-dimensional or two-dimensional bar code to a word processor or spreadsheet software generally used on a PC. Thus, it is possible to create a barcode with a small cost and work amount. In other words, without using the conventional bar code creation software,
You can easily create barcodes.
