DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to embodiments. FIG. 1 is a diagram showing an example of a plurality of character prints and a data code reader which are one of the prints with a data code of the present invention. FIG. 1A shows a plurality of character prints having a print character portion and a data code print portion.
FIG. 4 is a diagram illustrating a state in which a data code printed portion is scanned by a data code reader. In FIG. 1A, 1
Reference numerals a, 1b and 1c denote printed matter, 2 denotes a data code reader, 3 denotes a repeat button switch of the data code reader 2, and 4 denotes a scan button switch of the data code reader 2. FIG. 1B is a diagram illustrating an example of a print surface of a character print. In FIG. 1B, reference numeral 5 denotes a print character portion, and reference numeral 6 denotes an optically readable data code print portion including at least audio information.

As shown in FIG. 1A, a data code reader 2 is a pen-type reader, and optically reads a data code printing portion 6 including at least voice information by manual scanning. The repeat button switch 3 is a switch for repeating reproduction of the read audio information. The scanning button switch 4 is pressed to be turned ON when the data code reader 2 scans a data code printing portion. When the scanning button switch 4 is turned on, the data code reader 2 performs a data code reading operation.

FIG. 2 is a diagram showing a plurality of picture prints which are the other of the data code-added prints of the present invention. In FIG. 2, reference numerals 7a, 7b, 7c, 7d, 7e, and 7f denote picture prints having print picture portions corresponding to character prints. The plurality of character prints and the plurality of picture prints have a correspondence relationship. For example, a picture print corresponding to "SUNSET" which is a matter described in a certain character print 1a is a picture print 7a, and "sunset sun" is drawn on the picture print 7a as shown in FIG. .

As is apparent from the above configuration, FIG. 1 shows a learning card in the form of carta or carta. The printed matter with the data code of the present invention is a set of a character printed matter (reading card) and a picture printed matter (picture card). And a plurality of printed materials. 1 and 2, a plurality of picture prints 7a,
7b are arranged at random so that there is no regularity in each arrangement of the picture prints, and on a plane so as not to overlap. On the other hand, a plurality of character prints 1
are randomly superimposed so that the arrangement of the character prints is not regular.

[0010] Normally, the data code reader 2 reads the uppermost character print out of the superimposed character prints. Reading is performed by manually scanning (for example, by a teacher) on the data code printed portion of the character print while holding down the scan button switch 4 with a finger. By this manual scanning, a data code including at least audio information is optically read. The data code reader 2 performs data processing on the read data code to reproduce sound (described later).

Thereafter, when the read voice information is repeatedly reproduced, the reproduction is performed by pressing the repeat button switch 3 with a finger. Although the repeat button switch 3 and the scanning button switch 4 are shown as separate switches in FIG. 1A, the functions of these switches can be executed by one switch. For example, when the button switch is double-clicked, the button switch operates as the repeat button switch 3, and when the button switch is kept pressed, the button switch operates as the scan button switch 4.

When the voice is reproduced, a picture print corresponding to the reproduced voice is searched for from a plurality of picture prints 7a, 7b,... Arranged at random. Usually, a plurality of persons (for example, learners) perform an action of finding, and the picture printed matter found is the one found first. The game is advanced by playing back the superimposed character prints in order from the top, playing the final character print, and finding the corresponding picture print, and the game ends. Then, the winning or losing of the game and the ranking are determined according to the number of the picture prints found.

In the case where the voice reproduced in this way is a language learning term, listening to the voice is carefully performed so that listening training is performed. In addition, by finding a picture print corresponding to the reproduced voice, learning of the concept that the term means is performed at the same time. In addition, the character print 1a
When the printed character portion of (1b, 1c,...) Is read (for example, by a learner), it has a learning effect of reading, and can be confirmed by proper sound reproduction reproduced by the device. Moreover, they can proceed while enjoying them.

Here, the data code of the data code printing portion 6 shown in FIG. 1B will be described. The data code printing portion 6 can print a two-dimensional dot code in which dots are two-dimensionally arranged. The two-dimensional data code that can be used in the present invention is, for example,
A dot code as described in JP-A-6-231466 can be used.

FIG. 3 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. 3, 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. 4 is a diagram illustrating 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 of the data code print portion 6 shown in FIG. 1B is composed of ten blocks. In the data code print portion 6, as shown in FIG. Address (1,
0). On the other hand, the block on the right is the block address (1, 1), and so on.
(1,3), (1,4), then move to the lower row and (1,5), (1,6), (1,7), (1,8),
A block address is assigned to all the address blocks 42 in the format (1, 9). 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. 4B, 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. 3, the marker is located at the upper left of the block, and the block address is located at the lower right. However, in FIG. 4, 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. 4C, 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. 4D, the image magnification of the image forming optical system in the data code reader (to be described later) is determined by 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 order to improve the reliability of detection, the dot pitch is set to 1.5 in the example shown in FIG.
Detect by pixel.

The above-mentioned method (two-dimensional block division method) for the data code has the following advantages. 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, the two-dimensional block division system 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. FIG. 5 is a diagram showing an example of the configuration of a pen-type data code that can be used in the present invention. In FIG. 5, 5
0 is an earphone, 51 is a pen-type data code reader, 52
Is a touch sensor. Further, inside the pen-type data code reader 51, 60 is a light source such as an LED, 61 is an imaging lens, 62 is a spatial filter, 63 is an imaging unit such as an image sensor, 64 is an amplifying unit, and 65 is image processing. Department,
66 is a data processing unit, 67 is a data output unit, 68 is a control unit, and 69 is a battery as an operation power supply.

As shown in FIG. 5, the pen-type data code reader 51 includes a light source 60, a lens (imaging optical system) 61, a spatial filter 62, an imaging unit (image sensor) 63, an amplification unit 64, and an imaging control unit. Control section 6
8, the data code is detected. Further, the data obtained by the detection is subjected to scan conversion, binarization processing, demodulation, data error correction,
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. 5 is described in the above-mentioned Japanese Patent Application Laid-Open No. Hei 6-231466, and the description is omitted here.

When the control unit 68 as the imaging unit control unit keeps pushing the touch sensor 52 with a finger, the reading of the data code is continued during that time. Then, when the finger is released from the touch sensor 52, the reading is stopped. Further, when the control unit 68 as a sound reproduction control unit double-clicks the touch sensor 52 with a finger, the control unit 68 reproduces the stored sound data.
