FIG. 2 shows an example of the actual print pattern of the information block. The information block B includes the divided data D, the address A indicating the position information of the block in the code, or the label L indicating the type of the blocking code.
And consists of A mark M is provided between the blocks, and the mark M serves as a mark for detecting the range of the block. Since it is known that information is represented by such a blocking code, further detailed description of the information block will be omitted here.

Next, referring to FIG. 3, the required information is shown in FIG.
A procedure of a method of creating and printing as a plurality of information blocks shown in will be described. It should be noted that, in the present specification, what is printed by representing required information as a plurality of information blocks as described above is referred to as blocked code print information. This block code printing information can record not only audio information but also video information or character information. The voice information is converted into an analog electric signal in step 21 of inputting with a microphone, converted into a corresponding digital voice signal in step 22 of A / D (analog / digital) conversion, and information indicating that it is a sound is added in step 23. . Video information is input to the video camera Step 24
Is converted into an analog electric signal by A / D (analog / digital) conversion in step 25, and converted into a corresponding digital video signal, and in step 26, information indicating that the video is added is added. On the other hand, the character information is input as character code information by the keyboard input step 27, and information indicating that it is a character is added at step 28.

The respective information from steps 23, 26 and 28 are assembled as data 1 and data 2 according to the type of the data. Taking a learning sheet as an example, for example, English information is assembled as data 1 and Japanese information is assembled as data 2 (steps 29, 3).
0). However, in this embodiment, the only information to be recorded is English voice data, and therefore, steps 21 to 21 are performed.
The information prepared in 30 contains only English voice information.

In step 31, the binary English voice information prepared as described above is divided into blocks of fixed length,
The number of blocks is n, and a unique address is added to each block code (step 32). Note that in step 32, either the address or the label indicating the type of the blocking code is added, but in the present embodiment, since there is only one type of information, no label is added.

In this way, the information to be recorded is divided into blocks of a fixed length, and a set of data composed of a plurality of blocks in which an address indicating block position information in the code is added to each block code is prepared. Then, a code is generated based on this set of data (step 33),
The code is printed on the paper 1 according to the generated code (step 34).

Next, the structure of an apparatus for reproducing the blocked code print information printed on the paper 1 in this manner will be described.

FIG. 4 is a block diagram showing the structure of a reproducing apparatus for reproducing blocked code print information. In the reproducing apparatus 40, 41 is a pen-shaped code reader, and has a main body 43 in which an image capturing unit 42 for capturing the blocked code print information printed on the paper 1 is incorporated.
A reproduction processing unit (not shown) for processing the captured image data to obtain reproduction information data according to the captured information is incorporated in the main body 43. The reproduction information data from the main body 43 is the speaker 44, depending on the type of reproduction information.
The audio information, the video information, and the character information are reproduced by the monitor television 45 and the display device 46, respectively. In the present embodiment, only the reproduction of audio information is executed.

FIG. 5 is a detailed block diagram of the reproducing device 40. The reproducing apparatus 40 scans the imaging section 42 provided at the tip of a pen-shaped code reader 41 on the paper 1 shown in FIG. 1 so as to trace the blocked code print information printed on the paper 1. Therefore, a manual scanning type reading method is adopted in which the information blocks B _{1 to} B _n are read one after another as image data. Here, the reading of the code by the pen-shaped code reader 41 is performed by reading the information blocks B ₁ , B ₂ , ..., B _n in this order, or by reading the information blocks B _n , B _n-1 ,. It has been promised to either read in ₁ of the order. That is, start reading from the information block B ₁ and scan in the right-hand direction, or
Alternatively, the reading is to be started either from the information block B _n and scanning in the left-hand direction.
The input signal S read from the image pickup unit 42 in this way
₁ is stored in the frame memory 47. That is, the input signal S ₁ is binarized by the image processing unit 48, blocks are separated based on the mark (M), decoded, and stored in the frame memory 47 as binary data. Incidentally, since the configuration itself of processing the input signal S ₁ as described above and storing the contents of the information blocks B _{1 to} B _n in the frame memory 47 as binary data is well known, a more detailed description will be given here. Is omitted.

In this way, the binary data stored in the frame memory 47 is sent to the separating section 49, where the address and the data are separated for each of the information blocks B _{1 to} B _n . As for the addresses separated by the separation unit 49, the addresses of the information blocks read for the first time are stored in the first memory 50 and the second memory 51. The addresses of the information blocks read from the second time onward are stored in the second memory 51, where they are sequentially written by overwriting and stored. Therefore, when the information block printed on the paper 1 is scanned rightward by the pen-shaped code reader 41, the address AD ₁ of the information block B ₁ is stored in the first memory 50 and the second memory 51, Addresses of subsequent information blocks are sequentially overwritten and stored in the second memory 51. On the other hand, when the information block printed on the paper 1 is scanned toward the left by the pen-shaped code reader 41, the address AD _n of the block B _n is stored in the first memory 50 and the second memory 51. The addresses of the subsequent information blocks are sequentially overwritten and stored in the second memory 51.

The addresses stored in the first memory 50 and the second memory 51 are fetched by the discriminating unit 52, and by comparing the two addresses, the pen-shaped code reader 41 can read in either direction. It is determined whether or not the scanning has been performed, and the reproduction mode is selected according to the determination result. In the present embodiment, when reading scanning is performed in the right-hand direction as in the information blocks B ₁ , B ₂ , ..., The reproduction speed of information is set to the normal speed, and the information blocks B _n , B _{n- When} the reading scanning is performed in the left-hand direction as shown in ₁ , ..., The discriminating portion 52 outputs the reproduction speed command signal S ₂ for making the reproduction speed of the information slower than usual. Is.

The data and addresses separated by the separating unit 49 are sent to the reproduction information memory 53 in the order of reading and stored in the reproduction information memory 53 according to the address information. Therefore, the reproduction information data formed by assembling the data in the order according to the address is stored in the reproduction information memory 53 regardless of whether it is read from the right hand or the left hand direction.

The reproduction information data in the reproduction information memory 53 is classified by the data classification section 54 depending on which information is audio information, video information or character information, and the classified reproduction information data depends on the type of information. It is sent to the output device. Here, since all the reproduction information data is audio information, it is sent to the D / A (digital / analog) converter 55, where it is converted into an analog signal, and then the speaker 44.
Is input to D / A (digital / analog) converter 5
5, the reproduction speed command signal S ₂ is input from the discriminating unit 52, and the D / A (digital / analog) converter 55 digitally outputs at a clock speed according to the reproduction speed command signal S _2.
It is converted into analog, and thereby, it is possible to reproduce the English conversation voice which is the required voice information at the reproduction speed according to the reproduction speed command signal S ₂ . Reference numeral 56 denotes a D / A (digital / analog) converter for digital-analog converting the video information from the data classification unit 54, and the data classification unit 54 outputs the video information. In this case, the video signal analogized by the D / A (digital / analog) converter 56 is input to the monitor television 45, and a desired video is displayed here.
Further, the character information output from the data classification unit 54 enters the display device 46 as it is, and the character information is displayed here.

According to this structure, when the printed information on the conversation learning card is manually scanned by the pen-shaped code reader 41 to reproduce the English conversation voice information recorded therein, the manual scanning is performed in the right hand direction. The reproduction speed can be selected to be normal or low depending on whether the operation is performed in the left-hand direction or in the left-hand direction, and the usability is remarkably improved as compared with the conventional device which operates the changeover switch one by one.

In the present embodiment, an example in which the reproduction speed is selected depending on whether the learning sheet is scanned in the left or right direction has been described, but the present invention is not limited to this embodiment. However, the present invention may be configured to perform other function selection, for example, switching or selection of various operation modes such as switching of pitch level during reproduction.

Although the embodiment of the invention according to claim 1 has been described with reference to FIG. 5, it is performed in FIG. 5 by causing a microcomputer to execute a required program instead of the configuration shown in FIG. It is also possible to configure a playback device that performs the same function as the above function.

In FIG. 6, a microcomputer is used,
There is shown a reproducing apparatus 60 configured to reproduce the blocked code print information optically read according to a predetermined data processing program so as to reproduce the information. In the reproducing apparatus 60, 61 is a microcomputer, which is a central processing unit (CPU) 62, a read-only memory (ROM) 63, a first memory 64, a second memory 65, a random access memory (RAM) 66.

A monitor television 45 and a display device 46 are connected.
A data processing program for processing the imaging data from the imaging unit 42 is stored in the read-only memory (ROM) 63 in advance, and the imaging data read from the imaging unit 42 is processed by this data processing program. Information blocks B ₁ , B ₂ , ... By scanning the conversation learning sheet shown in FIG.
.., B _n is read, reproduction of an English conversation at a normal speed is obtained by the speaker 44, and the conversation learning sheet shown in FIG. _When the reading of _n , B _n-1 , ..., B ₁ is performed, the speaker 44 can reproduce the English conversation slower than the normal speed.

Next, with reference to FIG. 7, the reproducing apparatus 60
The operation of will be described. FIG. 7 is a flow chart showing a data processing program for reading and reproducing the block code print information. When the activation of the data processing program is started, the image data from the image pickup unit 42 is input in step 71. In step 72, the binarization is executed. In step 73, the mark (M) is discriminated from the information block based on the binarized image data, and the information block is cut out from the binarized image data. In step 74, the presence / absence of an information block is determined. If there is an information block, the determination result is YES.
Then, step 75 is entered.

In step 75, the data block and the address are separated from the information block, and the information blocks are extracted. In step 76, it is determined whether or not the information block processed in step 75 is the first information block of the information blocks obtained from the imaging unit 42 by the current scanning. If it is the first information block, step 77 is entered, where the address of the first information block is stored in the first memory 64. After that, step 7
After this address is also stored in the second memory 65 at 8, the random access memory (RAM) 66 stores the address and data of the information block at step 79.
Stored in, return to step 71, and again step 71 to
Repeat 79. If it is determined in step 76 that it is not the first information block, the determination result in step 76 is NO and step 78 is entered without executing step 77, and the address of the information block at that time is the second memory 64. Is overwritten and stored.

That is, the information block read by the image pickup unit 42 is separated into an address and data, and only the address of the information block read first is stored in the first memory 64 and the second memory 65, and the second time. The addresses of the information blocks read thereafter are sequentially written and stored in the second memory 65 by overwriting. On the other hand, the address and data of each information block are sequentially stored in the random access memory (RAM) 66, and when it is determined in step 74 that there is no information block to be processed, step 80 is entered.

At step 80, the values of the addresses stored in the first memory 64 and the second memory 65 are compared, and the reading direction of the information blocks B _{1 to} B _n is detected by the comparison. In this embodiment, the size of the address is AD ₁
= 1, AD ₂ = 2, ..., AD _n = N, so that the value of the address stored in the first memory 64 is smaller than the value of the address stored in the second memory 65, for example. Toward the right hand side, information blocks B ₁ , B
It is detected that scanning is performed in the order of ₂ , ..., B _n .
In the case of reading in the reverse direction, it can be similarly detected by comparing the value of the address.

In step 81, data is restored based on a plurality of sets of information blocks consisting of addresses and data stored in the random access memory (RAM) 66, and reproduction information data is obtained. In step 82, it is determined whether the reproduction information data obtained in step 80 is audio information, video information, or character information based on a code indicating the type of information attached in advance.

Next, referring to FIG. 12, the reproducing apparatus 1
The operation of 10 will be described. FIG. 12 is a flowchart showing a data processing program for reading and reproducing the block code printing information. When the activation of the data processing program is started, the image data from the image pickup unit 92 is input in step 121. At step 122, the binarization is executed. At step 123, the mark (M) is discriminated from the information block based on the binarized image data, and the information block is cut out from the binarized image data. In step 124, the presence / absence of an information block is determined. If there is an information block, the determination result is YES, and step 125 is entered.

In step 125, the information block is separated into a label and data, and each is extracted. In step 126, it is determined whether or not the information block processed in step 125 is the first information block of the information blocks obtained from the imaging unit 92 by this scanning. If it is the first information block, step 127 is entered where the label of the first information block is stored in the first memory 114. Then, in step 128, this label is also stored in the second memory 115, and then in step 129 the first memory 11 is stored.
It is determined whether or not the contents of 4 and the contents of the second memory 115 match. The first memory 1 at the time of the first reading
Since the content of 14 and the content of the second memory 115 are the same, the determination result of step 129 is YES, and step 130
Label and data in random access memory (R
AM) 116 and return to step 121. In this way, steps 121 to 130 are repeated each time the information block is read. At the time of the second and subsequent reading, the determination result of step 126 is NO, and step 12
7 is not executed but step 128 is entered and the label of the information block at that time is overwritten and stored in the second memory 115.

As a result, in steps 127 to 129, only the data and label of the information block which matches the label content read the first time are stored in the random access memory (RAM) 116 in step 130. That is, scanning of the conversation learning sheet is performed by the information block B.
When starting from J _1, since the label LJ added to this is stored in the first memory 114, only the information blocks BJ _{1 to} BJ _m are stored in the random access memory (R
AM) 116. On the other hand, when the scanning of the conversation learning sheet is started from the information block BE _1, the label LE added to this is stored in the first memory 114, so only the information blocks BE _{1 to} BE _n are random access memory. It is stored in the (RAM) 116.

That is, the information block read by the image pickup unit 92 is separated into a label and data, and only the label of the first read information block is the first memory 11.
4 and the second memory 115, the labels of the information blocks read after the second time are sequentially overwritten and stored in the second memory 115. On the other hand, as for the label and data of each information block, only those having a predetermined label are sequentially stored in the random access memory (RAM) 116, and when it is determined in step 124 that there is no information block to be processed, step 131 is entered. .

In step 131, the data is restored based on the plurality of sets of information blocks consisting of the label and the data stored in the random access memory (RAM) 116, and the reproduction information data is obtained. In step 132, it is determined whether the reproduction information data obtained in step 131 is audio information, video information, or character information based on a code indicating the type of information attached to the restored data in advance. It

In the present embodiment, since the information is voice information, step 133 is entered, where the reproduction information data is D / A.
(Digital / analog) conversion is performed, and reproduction is performed by the speaker 94 in step 134.

If it is determined in step 132 that the type of information is video information, image decoding is performed in step 135, and reproduction is performed on the monitor television 95 in step 136. If it is determined in step 132 that the type of information is character information, step 137 is entered, in which the reproduction information data obtained in step 131 is reproduced, and the display device 96 displays the character information.
