FIG. 3 is a picture book in a picture-story show format, as apparent from the above configuration. The printed matter with the data code is a series of plural sheets (31a, 31b,
…)). In FIG. 1, a frontmost side 31a and a rearmost side 31b are shown, and the others are ring-bound with being sandwiched between them. In the picture-story show picture book shown in FIG. 3, the printed matter 31b with the data code, which was located on the front side of the series of the printed matter with the data code, is turned to the back side when the story of the scene is finished, and becomes a newly printed matter with the data code. 31a is the outermost side. FIG. 3 shows this state. The data code surface 33b of the printed matter 31b with the data code on the bottom side appears on the bottom side of the picture book in a picture-story show format.

That is, the data code printing portion corresponding to the contents of the character / picture printing portion of a certain printed matter is provided on the printed matter one sheet before (or one sheet after). Since the data code surfaces 33a and 33b are the same as those already described with reference to FIG. 2, the details are omitted here.

Here, the data codes of the data code printing portions 21a to 21e shown in FIG. 2 will be described. A two-dimensional dot code in which dots are two-dimensionally arranged can be printed on the data code printing portions 21a to 21e. As the two-dimensional data code that can be used in the present invention, for example, a dot code described in Japanese Patent Application Laid-Open No. 6-231466 can be used.

FIG. 4 is a diagram showing an example of the configuration of a two-dimensional data code that can be used in the present invention. In FIG. 4, 41 is a dot code, 42 is a block, 43 is a marker, 44 is a block address, 45 is error correction data, and 46 is a data area. In one example of the two-dimensional data code, the data format of the dot code 41 is such that one block 42 is composed of a marker 43, a block address 44, an address error detection and error correction data 45, and actually data such as voice and image. And an input data area 46. As the marker 43, a pattern which does not normally come out by recording modulation is used. The block address data 44 is data representing the position of the block, and includes error detection and error correction data 4.
Numeral 5 is used for error determination of the address. The recording data in such a format is printed such that "1" and "0" have black dots and "0" has no black dots, for example, like a bar code, for example.

FIG. 5 is a diagram for explaining details of a two-dimensional data code that can be used in the present invention. Block 42
Are two-dimensionally arranged as shown in FIG.
Each block address 44 is added. The block address 44 is provided with each address. For example, the data code printing part 2 shown in FIG.
Each of the data codes 1a to 21e is composed of 10 blocks, and in the data code print portion 21a,
As shown in FIG. 5A, the upper left block is a block address (1, 0). On the other hand, the block on the right side is the block address (1, 1), and so on in the same manner as (1, 2), (1, 3), (1, 4). 1,5), (1,6), (1,7),
A block address is assigned to all address blocks 42 in the format (1, 8), (1, 9). Further, (2, 0),
(2,1),..., (2,9), (5,0), (5,1),
..., (5, 9), addresses are assigned to 50 data blocks. Of course, the number of blocks 42 can be freely changed depending on the amount of data to be recorded.

Here, the lowermost marker and the rightmost marker are dummy markers 48. That is, the block 42 for a certain marker 43 is the data at the lower right of the area surrounded by four markers 43 including the same,
The lowermost and rightmost markers are auxiliary markers, that is, dummy markers 48 arranged to define a block for the second lowermost marker and the second rightmost marker.
It is.

Next, the block 42 will be described. As shown in FIG. 5B, a block address 4 is provided between the marker 43 of the block 42 and the lower marker.
4 and its block address error detection and correction data 4
5 is given. Further, between the marker 43 and the right marker, a similar block address 44 and its error detection,
Correction data 45 is provided. In FIG. 4, the marker is located at the upper left of the block, and the block address is located at the lower right. However, in FIG. 5, the block address 44 is located at the left and upper sides, and the marker 43 is located at the upper left corner. And Although the block address 44 is shown as an example where it is recorded at two locations in one block, it may be at one location. However, by recording in two places,
Even if an error occurs due to noise on one block address, it can be detected by the other address, and higher reliability is obtained. The position of the data of the block with respect to a certain marker, the position of the block address, the position of the dummy marker on the code determined by the position, and the like are merely examples, and the present invention is not limited to this.

Next, a pattern example of the marker 43 will be described. As shown in FIG. 5C, in this example, the marker 4
3 is a circular black pattern 43 having a diameter of 7 dots.
A is used. The portion 43B around the black circle 43A is white, so that the black portion of the marker can be easily identified. Reference numeral 43C in the figure is an auxiliary line for explanation. The range of the white portion 43B is desired to be as small as possible to increase the recording density, but is required to be large in order to perform the marker detection processing easily and at high speed. Therefore, the black pattern 43A when the rotation is 45 degrees
Is set so that the range 43C for sufficiently discriminating is within the portion 43B.

As shown in FIG. 5D, the image magnification of the image forming optical system in the data code reader (to be described later) depends on the size of the data dot 49 in the data area 46.
It is assumed that the image magnification is 1.5 pixels. The pixels here are
It means one pixel of the image sensor of the image pickup unit of the data code reader. That is, the data code printing portions 21a to 21e
One dot recorded above, for example, a dot of 30 to 40 μm, is imaged through an imaging lens on 1.5 pixels of an image sensor which is usually 7 μm or 10 μm in size. . In the sampling theorem, the pixel pitch may be smaller than the dot pitch. However, in the example shown in FIG.
Detect by pixel.

By using the above-mentioned method (two-dimensional block division method) for the data code, the following advantages can be obtained. That is, the dot pitch for each dot is
If the resolution is equal to or less than the resolution of the image sensor, a code (a set of unit data blocks) can be read even if the data dot size is different. Reading is possible even if the imaging unit is inclined with respect to the code. Due to variations in scanning speed,
Reproduction is possible even if the interval between data dots varies. The unit block can be freely expanded two-dimensionally according to the total data amount, and as a result, the code size can be freely changed. Since each block address is added, even if reading is started in the middle of the code, the code can be reproduced. In block units, the shape of the code can be freely laid out. Predetermined start code and stop code as in barcode are unnecessary,
Also, no clock code is required.

In addition, because of these features, a two-dimensional block division method can realize a hand-held hand-held reader that can reproduce even if there is camera shake. In other words, the reader detects four adjacent markers and normalizes them by equally dividing the number of dots by the number of dots. Therefore, the reader is resistant to enlargement, reduction, deformation, and the like. There is an advantage that it is resistant to variations in intervals, camera shake during reproduction, and the like.

The dot 4 in the data area 46
For example, one dot has a size of several tens of μm. This can be achieved by appropriately setting the magnification of the data on the film at the time of printing depending on the application and use. Generally, 40 μm, 20 μm, or 8 μm
0 μm. The data area 46 is, for example, 64 ×
The size is 64 dots. These can be freely enlarged or reduced to a range in which the error due to the above-mentioned equal division can be absorbed. The marker 43 has a size that is not included in the modulated data. In the present embodiment, the marker 43 has a round shape and has a diameter of, for example, 7 dots or more or 7 × 7 dots with respect to the dots in the data area 46. It is a circular black marker 43A.

Next, the data code reader will be described. As a data code reader that can be used in the present invention, for example, a data code reader described in JP-A-6-231466 can be used.

Data processing is performed by functions such as decompression processing, data interpolation, and address order detection. Then, the data is converted into an audio signal by the data output section 67 and reproduced from the earphone 50. Although only an audio information output device is shown in this figure, when a processing unit for images, characters, line drawings, and the like is incorporated, an output device according to the output device can be connected. A specific operation mechanism for reading a data code by the pen-type data code reader 51 having the configuration shown in FIG. 6 is described in the above-mentioned Japanese Patent Application Laid-Open No. Hei 6-231466, and the description is omitted here.
