04 is used to read the two-dimensional barcode 305 recorded as shown in FIG. [0003] As shown in FIG. 8, the processing device comprises a code restoring unit 401 and an application software starting unit 402. The two-dimensional barcode 305 read by the scanner 303 is captured as an image by the scanner 303, and the data is read by the code restoring unit 401.
Send to The code restoring unit 401 restores the contents of the two-dimensional barcode 305 into code information. It should be noted that the restoration result is not limited to the code information, but may be image information. For example, information created by a word processor (word processor) or the like is code information. The information read by the scanner and represented by dots is image information. In the following, description will be given using image information as an example. The restored code information may be filed in a file format of a specific application, for example, in a DOS (disk operating system) file format. At this time, the data file is read and expanded by the application software activation unit 402 in order to expand the data file on a display device or the like, and is displayed on the display device 302. If the image information is simple dot data that does not depend on the application, the image information may be directly displayed on the display device 302. Since the two-dimensional barcode 305 is only information to be developed and does not record image information / code information and information on the necessity / unnecessity of an application, it is necessary to manually specify the two-dimensional barcode 305 in advance. . Thereafter, the file is read by the scanner 303, the file is restored, and the application is activated and displayed as needed. FIG. 10 is a flowchart showing an example of processing for restoring a file and starting and displaying an application as needed. First, a data type of a two-dimensional barcode is designated (step 501). Next, the two-dimensional barcode 305 is read by the scanner 303 (step 50).

FIG. 6 is a flowchart showing the processing operation in the configuration of FIG. 5, and the operation of the embodiment of FIG. 5 will be described with reference to this flowchart and FIG. Here, it is assumed that the document is composed of image information and code information (for example, an ASCII file). The external character data, font data, and application software used are recorded as two-dimensional bar codes. First, the document data (original) is converted by the conversion unit 13.
Filed by In this case, the conversion unit 13 creates a file such as a DOS file using application software (step 201). In this case, the image is converted into an image file 14 such as a TIFF (Tagged Image File Format) file, the character part is converted into a character part code information file 15, and the external character data and font data are converted into an external character / font file 16, respectively. Also, an application software file 17 is created to restore the original from the code information. Such processing is performed in steps 202, 203, and 204. The conversion section 13 separates the control information from the main data section and sends it to the control section generation section 19 (steps 202 and 205). Each of the file information thus coded and arranged in units of file type is input to the barcode generation unit 18, and each two-dimensional barcode is created (step 206). For the image, a two-dimensional barcode is created by the barcode generator 18 for the contents of the image file 14 (step 207).
On the other hand, the control unit generation unit 19 is provided with the position information (information indicating the pasting position of the image unit) from the conversion unit 13, and the barcode generation unit 18 provides the arrangement information (the position information where each file information is to be arranged). ) Is given. Based on these, the control unit generation unit 19 creates a two-dimensional barcode for the control unit 6a (Step 209). Here, the mixing unit 20 creates the data body 6b by putting together the two-dimensional barcodes of a plurality of files output from the barcode generation unit 18 (step 208). Next, the mixing unit 20 includes the control unit generation unit 19.
The control unit 6a output from the control unit 6 and the data body unit 6b created earlier are combined to create a two-dimensional barcode (step 210). The created two-dimensional barcode image is displayed on the display device 12 or printed out by the printer 4 (step 211). It should be noted that it is difficult to determine the two-dimensional bar code information with human eyes. Therefore, a part or the whole of the document may be displayed as an image in the margin of the two-dimensional barcode output result. Alternatively, only the secret part may be converted into a two-dimensional bar code. Alternatively, it is also possible to perform processing such that only the cover of the document is displayed and the rest is not displayed.
