  Embodiments of the present invention will be described below with reference to the drawings.

  First, the information reproduction system according to the first embodiment of the present invention will be described.

  FIG. 1 is a block diagram showing the configuration of the information reproducing system of the first embodiment.

  This information reproduction system is roughly composed of a reading unit 2, a data processing unit 4, and an output processing unit 6.

  The reading unit 2 includes an operation switch (OPSW) 22 that is operated by an operator to instruct start and end of reproduction processing, and a green light emitting diode (hereinafter referred to as LED) 24 that displays the state of reproduction processing by operation. , A red LED 26 for displaying an error relating to scanning, and an illumination unit, an optical system, and an imaging unit.

  The data processing unit 4 includes a controller 42 that controls the entire information reproduction system, an error correction processing unit 44, an analog processing unit 46, a code restoration processing unit 48, an image memory 50, and a data memory 52. And an I / O unit 54 and a power source 56 for supplying a driving voltage to the entire information reproducing system.

  The output processing unit 6 includes a controller 62 provided as a personal computer (hereinafter referred to as a personal computer) or an interface (I / F) card, a storage device 64, and an output device 66 such as a monitor and a speaker. Consists of.

  The signal of the operation switch 22 of the reading unit 2 is input to the controller 42 in the data processing unit 4, and the control signals of the green LED 24 and the red LED 26 are output from the controller 42, and the green LED 24 and the red LED 26 are red. The LED 26 is turned on and blinked.

  An imaging signal from the reading unit 2 is input to the analog processing unit 46 in the data processing unit 4. The imaging signal input to the analog processing unit 46 passes through the band limitation emphasis filter, is converted into digital data by adaptive binarization processing, and is output to the code restoration processing unit 48. The code restoration processing unit 48 performs control for storing the image signal of the input digital data in the image memory 50 and reading the image signal from the image memory 50, and also performs marker detection, arrangement direction detection, Code restoration processing such as dot detection and demodulation is performed, and the result is output to the data memory 52.

  The data memory 52 stores and stores input data. The data stored in the data memory 52 is subjected to interleaving, decoding and determination of header information by the controller 42, and the data is transferred to the error correction processing unit 44 and subjected to error correction. It is stored again in 52 different areas.

  The data stored again in the data memory 52 is output to the output processing unit 6 via the I / O unit 54. The data input to the output processing unit 6 is stored in the storage device 64 in the output processing unit 6 and output from the output device 66.

  That is, as the data flow, the data read by the reading unit 2 is written into the image memory 50 by the code restoration processing unit 48 via the analog processing unit 46, and the data in the image memory 50 is written by the code restoration processing unit 48. The restoration process is performed and the data memory 52 stores the data. The process so far is the code restoration process.

  Thereafter, the controller 42 performs reproduction processing such as interleaving, error correction, and header information decoding determination on the data stored in the data memory 52. Then, the output process is to output the data after the reproduction process to the output processing unit 6 to make a sound from the speaker, to display an image on the monitor, or to store in the storage device 64.

  Here, a general-purpose interface is used for the I / O unit 54, for example, GP-IB, RS232C, SCSI, or a PCMCIA interface of a personal computer.

  In the first embodiment, it is assumed that the access from the output processing unit 6 to the data memory 52 is handled as a PCMCIA memory. That is, the controller 62 can read and write the data memory 52 and handle it as a PCMCIA memory card, an I / O card, or a hard disk.

  Next, power saving processing in the information reproduction system of the first embodiment will be described.

  The control signal from the controller 42 to the reading unit 2, the control signal to the analog processing unit 46, and the control signal to the code restoration processing unit 48 are signals for instructing power saving processing at the start and end of each processing. is there. Further, the control signal from the controller 42 to the error correction processing unit 44 instructs the start of the error correction process and also instructs the power saving process. A control signal between the controller 42 and the I / O unit 54 is used to perform an input / output instruction or to adjust access to the data memory 52.

  The control signal from the analog processing unit 46 to the code restoration processing unit 48 is a clock signal, or a horizontal synchronization signal or a vertical synchronization signal. Control signals between the code restoration processing unit 48 and the image memory 50 are a read / write signal and an address signal. Similarly, control signals from the code restoration processing unit 48 to the data memory 52 are read / write signals, address signals, partial select signals, and the like.

  2 and 3 are flowcharts showing the processing of the controller 42 as the operation of the information reproducing system of the first embodiment.

  First, when the power source is turned on by AC power outlet connection, power switch on, or battery connection to the power source (step S1), both the green LED 24 and the red LED 26 are turned on (step S2). Initialization is performed (step S3). In this initialization, a memory test, a hardware interface check, and the like are performed.

  Next, a system abnormality is detected (step S4), and the controller 42 determines whether or not a system abnormality has occurred (step S5). If an abnormality has occurred in the system, the process jumps to step S36 to end the present process. On the other hand, if no abnormality has occurred in the system, both the green LED 24 and the red LED 26 are turned off (step S6).

  In the system abnormality detection, when a hardware interface is checked, if there is an abnormality, there is a case where there is no response and the operation stops as it is. Therefore, first, both the green LED 24 and the red LED 26 are turned on, and when it stops, the operator is notified of the abnormality. Also, the process is terminated when there is an error in the memory check, and both the green LED 24 and the red LED 26 are kept lit to notify the abnormality. That is, the system abnormality is determined from the three states that both the green LED 24 and the red LED 26 are turned on and the operation switch 22 is not pressed. .

  Subsequently, the controller 42 monitors the operation switch 22 (step S7), and determines whether or not the operation switch 22 is on (step S8). Here, when the operation switch 22 is off, the process returns to step S7, the operation switch 22 is repeatedly monitored and judged, and waits until it is turned on.

  When the operation switch 22 is turned on, the timer is cleared (step S9), the processing of the analog processing unit 46 and the code restoration processing unit 48 is started (step S10), and the green LED 24 is turned on (step S11). . The lighting of the green LED 24 indicates that the information reproduction system is activated, the pattern code can be read or being read, and the analog processing unit 46 and the code restoration processing unit 48 can be processed or is being processed. It is.

  Next, the controller 42 determines whether or not a block has been input by scanning the pattern code on the pattern code, that is, whether or not a code constituted by the block has been read (step S12). If a block is input, the timer is cleared (step S13), and the red LED 26 is turned off (step S14). In this case, the red LED 26 is originally turned off.

  At this time, the data input process is in progress in the analog processing unit 46 and the code restoration processing unit 48, and the data is automatically transferred from the code restoration processing unit 48 to the data memory 52. At this time, the block address obtained is transferred to the controller 42 using an interrupt to the controller 42, and the controller 42 creates a block management table. This block management table is a table for managing whether or not the block address is obtained based on the block address (step S15).

  Next, the controller 42 determines whether or not the operation switch 22 is off (step S16). If the operation switch 22 is not turned off, the process returns to step S12 to determine again whether or not a block has been input. On the other hand, when the operation switch 22 is OFF, the green LED 24 and the red LED 26 are turned off (step S17), and the analog processing unit 46 and the code restoration processing unit 48 are set to save power (step S18).

  Then, the block management table is read and the obtained block determination process is performed (step S19). Subsequently, the controller 42 determines whether or not the number of acquired blocks is 0, that is, no block has been acquired (step S20). Here, when the obtained block is “0”, the red LED 26 blinks twice to output a warning (step S21), and the process is terminated (step S36). On the other hand, when the number of obtained blocks is not 0, that is, when there is even one input block, it is determined whether or not the personal computer has finished reading the data previously input (step S23). This is to check whether or not the data input by the previous scan has been read from the output buffer of the data memory 52 by the personal computer. If the data has not been read, the previous data can be output. The scan data is also held in the data memory 52, and after the previous data is read, the data in the data memory 52 is processed so that the data for the current scan can also be output.

  Here, when reading of the data input immediately before is not finished, a warning is output by blinking the red LED 26 four times (step S24), and this processing is finished (step S36). . This warning output notifies the operator that the data output processing is performed by the previous scan. On the other hand, when reading is completed, data reproduction processing such as interleaving, error correction processing, and header information decoding determination processing is performed (step S25).

  Then, the controller 42 detects an error such as whether or not the error has been corrected in the error correction process or whether or not there is a problem in the header information, and determines whether or not there is an error (step S26). Here, when there is an error, that is, when reproduction cannot be performed, a warning is output by blinking the red LED 26 three times (step S27), and this processing is terminated (step S36). This warning output informs the operator of a scan error or damage such as a scratch on the code in this scan, or that logical information such as header information is not compatible with this information reproducing system. On the other hand, when there is no error, that is, when reproduction is possible, this processing is terminated as it is (step S36).

  Next, a description will be given of a case where a block is not input due to the scanning of the reading unit 2 on the pattern code in step S12. This is to time out or output a warning when block data does not enter while scanning the pattern code while pressing the operation switch 22.

  First, when no block is input, it is determined whether or not the input waiting state has passed for 10 seconds or more (step S28). Here, if 10 seconds or more have not elapsed, it is determined again whether or not the operation switch 22 is off (step S16), and the input of the block is awaited again. On the other hand, when 10 seconds or more have elapsed, the red LED 26 is turned on (step S29), and a warning is output that a block does not enter for 10 seconds or more.

  Then, processing for reading the block management table and determining the obtained block is performed (step S30). Subsequently, the controller 22 determines whether or not the block has been obtained (step S31). Note that “acquired” means that one block has been obtained in the past. Here, when the block has not been obtained, it is determined whether or not the input waiting state has passed for 30 seconds or more (step S32). If 30 seconds or more have not passed, it is again determined whether or not the operation switch 22 is off. Then (step S16), the process after step S16 is performed. On the other hand, when 30 seconds or more have elapsed, the analog processing unit 46, the code restoration processing unit 48, the error correction processing unit 44, etc. are set to save power as timeout (step S33), and the green LED 24 and the red LED 26 are turned off ( Step S34), the process is terminated (Step S36). This means that the code has not been operated from the beginning, and is terminated after 30 seconds or more, and the switch is kept pressed without any intention of the operator to scan the code. When the operation switch 22 is pushed when the reading unit 2 is put in the pocket, all the processes are ended and the power saving setting is made, and the usage time of the battery as a power source is lengthened.

  If the block has already been obtained in step S31, it is determined whether or not the input waiting state has passed for 20 seconds or more (step S35). It is determined whether or not it is off (step S16), and the processing after step S16 is performed. On the other hand, when 20 seconds or more have elapsed, the process jumps to step S33 as a timeout. Then, the processing after step S33 is performed, and this processing is terminated (step S36). This is to end because there is no intention to reproduce the code for 20 seconds, and the operator was willing to scan the code, but it was interrupted halfway or the scanning was ended but the operation switch 22 When scanning a plurality of codes, the operator is informed that some codes are codes that can be reproduced by the information reproducing system and other codes are codes that cannot be reproduced. Because.

  In steps S21, S24, and S27 in this flowchart, the red LED 24 is flashed twice, four times, and three times as a warning, but this flashing is not limited to this number. Any number of times is possible. In addition, the lighting time may be used instead of blinking, and the number of display LEDs that can distinguish the above states may be used.

  Next, the operation of the controller 62 in the output processing unit 6 will be described.

  FIG. 4 is a flowchart showing the processing of the controller 62 as the operation of the output processing unit 6.

  First, when the power is turned on and this process starts (step S41), initialization is performed (step S42).

  Next, the controller 62 monitors the writing of the reproduction data to the data memory 52 (step S43), and determines whether or not the writing of the reproduction data has been completed (step S44). If the writing has not been completed, the process returns to step S43 to repeat the reproduction data writing monitoring and the determination of whether or not the writing has been completed. On the other hand, when the writing is completed, the controller 62 reads the reproduction data from the data memory 52 and stores it in the storage device 64 based on the division information regarding the division of the pattern code (step S45). The division information will be described later.

  Subsequently, the division information is recognized and determined (step S46), and it is determined whether or not reproduction is possible (step S47). If reproduction is not possible, the process returns to step S43, and reproduction data write monitoring is performed again. This is a determination and processing for outputting the block data of all pattern codes when the pattern code is divided, and information for that is recorded on the pattern code. On the other hand, when the reproduction is possible, an output process, for example, a process of producing a sound or an image is performed (step S48).

  Then, this process is terminated, or the process returns to step S43 to monitor data input (step S49).

  FIGS. 5A and 5B and FIGS. 6A and 6B are time charts during the operation of the information reproducing system of the first embodiment.

  This time chart mainly shows the relationship between the operation of the operator, the operation of the data processing unit 4, and the LEDs 24 and 26 of the reading unit 2. “Operation” in FIG. 5 indicates the operation of the operator, that is, the operation switch 22 and the power on / off, and scanning on the pattern code by the reading unit 2. “Processing” indicates operations of the data processing unit 4 and the output processing unit 6. “Display” indicates a blinking state of the green LED 24 and the red LED 26 of the reading unit 2.

  Hereinafter, the time charts shown in FIGS. 5A and 5B and FIGS. 6A and 6B will be described in order.

  FIG. 5A is a time chart when a system abnormality is detected by the initialization process in step S2 in the flowchart shown in FIG.

  As shown in the figure, when the power is turned on as “operation”, initialization processing is performed as “processing”, and if the system is abnormal (error occurrence), the initialization processing is interrupted and “processing” is terminated. . At this time, as the “display”, the green LED 24 and the red LED 26 are turned on when the power is turned on, and since the system is abnormal in the initialization process, both the LEDs 24 and 26 are kept in the lit state as “operation”. When the power is turned off, both LEDs 24 and 26 are turned off.

  FIG. 5B is a time chart showing the basic operation when block data is input in step S12 in the flowchart shown in FIG.

  As shown in the figure, when the power is turned on as “operation”, initialization processing is performed as “processing”, and when there is no abnormality in the system and the system ends normally, the operation switch 22 is on standby. As the “display”, when the power is turned on, the green LED 24 and the red LED 26 are turned on. When the system is normally completed by the initialization process, both the LEDs 24 and 26 are turned off, that is, the green LED 24 and the red LED 26 are turned off. Is turned on during the initialization process and turned off when the initialization process is completed.

  Subsequently, the operation switch 22 is turned on as “operation”, and the pattern code is scanned. At this time, code restoration processing is performed when the operation switch 22 is turned on as “processing”, and the green LED 24 is turned on when the operation switch 22 is turned on as “display”.

  Then, when the operation switch 22 is turned off as “operation”, reproduction processing is performed as “processing”, and reproduction processing data is transferred to the personal computer of the output processing unit 6 or a warning is given. Waiting for ON and outputting playback or warning (PC processing). As the “display”, when the operation switch 22 is turned off, the green LED 24 is turned off, and as described in the flowchart of FIG. 3 described above, the red LED 26 blinks twice when no block is available. If the data is available but cannot be played back, it flashes three times. If the reading is not finished and the playback process cannot proceed, it flashes four times.

  FIG. 6A is a time chart showing an operation when block data is input after step S35 in the flowchart shown in FIG. 2 has elapsed.

  As shown in the figure, when the power is turned on as “operation”, initialization processing is performed as “processing”, and when there is no abnormality in the system and the system ends normally, the operation switch 22 is on standby. When the power is turned on as a “display”, the green LED 24 and the red LED 26 are turned on. When the system is normally completed by the initialization process, both the LEDs 24 and 26 are turned off. That is, the green LED 24 and the red LED 26 are turned on during the initialization process, and are turned off at the end of the initialization process.

  Subsequently, the operation switch 22 is turned on as “operation”, and the pattern code is scanned. At this time, code restoration processing is performed when the operation switch 22 is turned on as “processing”, and the green LED 24 is turned on when the operation switch 22 is turned on as “display”.

  Then, after the pattern code is scanned as “operation”, the red LED 26 is turned on as “display” after 10 seconds from the end of scanning. Then, before 10 seconds have elapsed, that is, before 20 seconds have elapsed from the end of scanning, when the pattern code is scanned and a block is input, the red LED 26 is turned off and only the green LED 24 is lit. It will be in the state.

  Then, when the operation switch 22 is turned off as “operation”, reproduction processing is performed as “processing”, and reproduction processing data is transferred to the personal computer of the output processing unit 6 or a warning is given. Waiting for ON and outputting playback or warning (PC processing). As the “display”, when the operation switch 22 is turned off, the green LED 24 is turned off, and as described in the flowchart of FIG. 3 described above, the red LED 26 blinks twice when no block is available. If the data is available but cannot be played back, it flashes three times. If the reading is not finished and the playback process cannot proceed, it flashes four times.

  That is, in this time chart, when the operator turns on the operation switch 22 and scans the pattern code, the block data is input, and after the scanning is stopped, the pattern code is scanned within 10 seconds. If there is no input of the block, the red LED 26 is lit to warn the operator to scan the pattern code and input the block.

  This warning is given when the pattern code is scanned but not input as block data. In other words, the case where the pattern code is not input is not only when the pattern code is not scanned, but also when the pattern code is actually scanned but the pattern code is not recognized as block data. For example, it includes a case where the format specification of the pattern code is different from the format specification of the pattern code that can be restored by the information reproducing system, or a portion where the pattern code does not exist is scanned.

  “Do not scan the code” in the “operation” in the figure means that the pattern code that can be read is not scanned, and the above warning causes the operator to scan the normal pattern code. To instruct.

  FIG. 6B is a time chart showing the operation when no input of block data is made when the input waiting state has passed for 30 seconds or more in step S32 in the flowchart shown in FIG.

  As shown in the figure, when the power is turned on as “operation”, initialization processing is performed as “processing”, and when there is no abnormality in the system and the system ends normally, the operation switch 22 is on standby. When the power is turned on as a “display”, the green LED 24 and the red LED 26 are turned on. When the system is normally completed by the initialization process, both the LEDs 24 and 26 are turned off. That is, the green LED 24 and the red LED 26 are turned off. Lights during the initialization process and turns off when the initialization process ends.

  Subsequently, even if the operation switch 22 is turned on as “operation”, the pattern code is not scanned. At this time, code restoration processing is performed when the operation switch 22 is turned on as “processing”, and the green LED 24 is turned on when the operation switch 22 is turned on as “display”. Thereafter, after the operation switch 22 is turned on, the red LEL 26 is lit after 10 seconds.

  Then, since the pattern code is not scanned for another 20 seconds, that is, before 30 seconds have elapsed since the operation switch 22 is turned on, the code restoration processing is terminated as “processing”, and the green LED 24 and the red LED 26 are turned on as power saving processing. Turn off and end.

  That is, in this time chart, when the block code is not input by scanning the pattern code within 10 seconds after the operation switch 22 is turned on, the operator scans the pattern code. In order to prompt the user to input block data, the red LED 26 is turned on to give a warning, and if no block data is input within 20 seconds after the warning, the green LED 24 and the red LED are automatically set as a power saving measure. The LED 26 is turned off and the power saving process is completed.

  This warning is issued when one block data is not input even if the pattern code is scanned. The case where the block data is not input is not only the case where the act of scanning the pattern code is not performed as in the case described with reference to FIG. 6A, but also the actual scanning of the pattern code. However, if the pattern code is not recognized as block data, for example, the format specification of the pattern code is different, the part where the pattern code does not exist is scanned, or there is no intention to scan the pattern code The case where the reading unit 2 is tilted and the operation switch 22 is turned on is included.

  That is, “do not scan the code” means that the readable pattern code is not scanned, and instructs the operator to scan the normal pattern code by the warning. It is. Note that the delay in turning on and off the “display” green LED 24 and the red LED 26 with respect to the “operation” and “processing” operations is a time lag that occurs in actual implementation.

  Next, a memory map of the data memory 52 constituting the information reproducing system of the first embodiment will be described.

  7A and 7B are diagrams showing a memory map of the data memory 52. FIG.

  FIG. 4A is a diagram showing the entire memory map of the data memory 52, and FIG. 4B is a diagram showing a block management table in the memory map.

  The data memory 52 includes a block data area 70, an output buffer 72, and a block management table 74.

  The capacity of the data memory 52 assumed here is 64K bytes = 65536 bytes, of which 32K bytes = 32768 bytes as the block data area 70, (32768-4096) = 28672 bytes as the output buffer 72, block management table 4096 bytes are assigned as 74.

  In the output buffer 72, reproduction processing data after error correction, that is, a subset is written. This subset is a unit of reproduction data that can be output (reproduced), for example, a unit of reproduction data that can be output, such as sound, text, image, or a combination thereof.

  The data of each block restored by the code restoration processing unit 48 is written one by one at an address corresponding to each block address in the block data area 70 of the memory map. That is, the block addresses 1, 2, and 3 represent predetermined addresses on the block data area 70, and a data area is prepared for each block address and written therein.

  The area of the output buffer 72 is slightly smaller than the block data area 70. This is because the error correction code and the like are removed from the block data and written to the output buffer 72, so the amount of data is reduced. Therefore, there is no problem even if it is prepared slightly smaller than the block data area 70. It is.

  Here, the number of data of one block data is 256 bytes. Then, since there is a block data area 70 of 32 Kbytes, data for a total of 128 blocks can be stored.

  The block management table 74 is used to determine whether block data has been acquired or not. Therefore, one bit address is sufficient for one block address, and in order to manage information for 128 blocks on a one-to-one basis, it is only necessary to store data for 128 bits. Here, an area of 4096 bytes is secured, but it is sufficient to use 128 bytes of that area.

  That is, the data memory 52 has a block data area 70 in which each block data of the reproduction data is assigned on a one-to-one basis for each address, and the reproduction data stored in the block data area 70 is output. There is an output buffer 72 that is temporarily used, and a block management table 74 that indicates the presence or absence of block data. The block management table 74 has an area corresponding to each block address on a one-to-one basis. By having the block data area 70 allocated one-to-one for each block address, the operator scans the reading unit 2 not only in regular scanning such as scanning along the code, but also in irregular. Scanning is possible. The addresses of the obtained blocks are also obtained in an irregular order by irregular scanning, but reproduction is possible because there is a block data area 70 for each block. Further, by providing the output buffer 72 separately from the block data area 70, it is possible to hold data obtained by scanning twice.

  Next, division information related to pattern code division will be described.

  FIG. 8A is a diagram for explaining a pattern code and user data.

  The pattern code is recorded in one file format with header information added to information (hereinafter referred to as user data) such as sound, text, and image in an information recording system capable of generating the pattern code.

  In this information reproduction system, 128 block data can be taken in according to the pattern code of the file format according to the size of the block data area 70 on the data memory 52 of the data processing unit 4 and the size of the output buffer 72. ing. In other words, this means that only 128 block data can be reproduced.

  Therefore, one method for reproducing user data larger than 128 block data is pattern code division, which will be described below.

  As described above, when the user data is larger than 128 block data, the reproduction data is larger than the block data area 70 and larger than the output buffer 72 and cannot be reproduced by the information reproduction system. .

  Therefore, as shown by division information 1, division information 2, and division information 3 in FIGS. 8B1 to 8B3, user data is divided and header information is added to each divided user data. In the header information, information indicating that the data is divided and information for connecting the respective user data are recorded. Then, each of the divided information 1, divided information 2, and divided information 3 is formed into a pattern image in the information recording system, and three respective pattern codes as shown in FIGS. 8C1 to 8C3 are created.

  When the pattern code created from the division information is to be reproduced in this information reproducing system, the three codes are sequentially scanned. That is, the operation switch 22 is turned on, the pattern code shown in FIG. 8C1 is scanned, and the operation switch 22 is turned off. Subsequently, the operation switch 22 is turned on, the pattern code shown in FIG. 8C2 is scanned, and the operation switch 22 is turned off. Subsequently, the operation switch 22 is turned on, the pattern code shown in FIG. 8C3 is scanned, and the operation switch 22 is turned off. The above three scans are performed for reproduction. In the above-described example, scanning is performed in the order of FIGS. 8C1 to 8C3. However, the order of the three scans may be started from anywhere, and another pattern may be used while the three pattern codes are scanned. Don't scan the code.

  Since this information reproduction system is a device that can reproduce only up to 128 blocks, reproduction processing is performed by scanning the block data area 70 of the data memory 52 with the pattern code shown in FIG. After being stored in the block data area 70, it is stored in the output buffer 72. Then, the data in the output buffer 72 is immediately transferred to the output processing unit 6 side, and the next pattern code shown in FIG. 8C2 is scanned at the next time point. At this time, since the block data area 70 is already vacant, the block data of the pattern code shown in FIG. 8 (c2) is newly stored therein, and this block data is also processed and output from the output buffer 72. It is transferred to the output processing unit 6 side. In this way, the block data of each pattern code is transferred one after another, combined by the output processing unit 6 and output.

  At this time, as shown in the flowchart of the process in the controller 62 of the output processing unit 6 shown in FIG. 4 described above, the controller 62 of the output processing unit 6 determines from the division information of the block data input from one pattern code. In the example shown in FIG. 8, it is determined whether or not three block data are available, and whether or not reproduction is possible is determined. If the three block data are available, the output process is performed and the process ends.

  As a result, the information that can be reproduced with the capacity of the data memory 52 of the information reproduction system, that is, the size of the user data is not limited, and larger information can be created.

  Note that “1” shown in FIG. 8C1 is the smallest block address number of the pattern code in which data is stored, and “100” is the largest block address number in the pattern code in which data is stored. It is. Similarly, each of “1” and “90”, “20” and “128” shown in FIGS. 8C2 and 8C3 has the smallest block address number and the largest pattern code in which data is stored. Block address number. In addition, this information reproducing system can reproduce data between any number of block address numbers starting and ending.

  The pattern code created from the division information is a subset of one outputable minimum unit, and this subset may be one outputable unit of image, text, sound, etc. One outputable unit composed of a combination of sounds or the like may be used.

  Next, the relationship between the operation of the operation switch 22 and the processing of the controller 42 in the data processing unit 4 will be described. The flowchart shown below is ergonomically considered for the processing relationship of the controller 42 by the operation of the operation switch 22, and the processing of the controller 42 of the data processing unit 4 shown in the flowcharts of FIGS. From the above, the processing portion by the operation of the operation switch 22 is extracted and shown.

  FIG. 9 is a flowchart showing a process to be performed when the pattern code is scanned while the operation switch 22 is being pressed, and the pressing is stopped.

  When the power is turned on (step S51), the controller 42 monitors the operation switch 22 (step S52), and determines whether or not the operation switch 22 is on (step S53). If the operation switch 22 is off, the process returns to step S52, and the operation switch 22 is repeatedly monitored and determined, and waits until it is turned on.

  When the operation switch 22 is turned on, the analog processing unit 46 and the code restoration processing unit 48 are started (step S54).

  Next, the controller 42 determines whether or not the operation switch 22 is off (step S55). Here, when the operation switch 22 is not turned off, the determination at step S55 is repeated, and when the operation switch 22 is turned off, the processes of the analog processing unit 46 and the code restoration processing unit 48 are terminated (step S56).

  Subsequently, data reproduction processing is performed (step S57), output (step S58), and this processing is terminated (step S59).

  In the operation of the operation switch 22 according to this flowchart, the operation switch 22 is pressed to scan the pattern code, and after the scanning, the operation switch 22 is released. The operation is simple and easy to understand. If it is used as it is as a control signal for power saving processing, the power saving processing can be easily performed and the circuit for that can be simplified.

  FIG. 10 is a flowchart showing a process of scanning and outputting a pattern code by clicking the operation switch 22. Here, the click means a series of operations in which the operation switch 22 is turned on and the switch is turned off in a short time.

  When the power is turned on (step S61), the controller 42 monitors the operation switch 22 (step S62), and determines whether or not the operation switch 22 has been clicked (step S63). If the operation switch 22 has not been clicked, the process returns to step S62 to repeatedly monitor and determine the operation switch 22, and wait until the operation switch 22 is clicked. The click here means one click.

  If the operation switch 22 is clicked, the analog processing unit 46 and the code restoration processing unit 48 are started (step S64).

  Next, the controller 42 determines whether or not the operation switch 22 has been double clicked (W click) (step S65). Here, when the operation switch 22 is not double-clicked, the determination in step S65 is repeated, and when the operation switch 22 is double-clicked, the processes of the analog processing unit 46 and the code restoration processing unit 48 are ended (step S65). S66). The double click (W click) here means two clicks.

  Subsequently, data reproduction processing is performed (step S67), output (step S68), and this processing is terminated (step S69).

  In the operation of the operation switch 22 according to this flowchart, the scanning of the pattern code is started by clicking the operation switch 22, and after the scanning, the operation is finished by double clicking (W click). Since there is no need to perform two operations of scanning, it is possible to concentrate on one operation of pattern code scanning and to eliminate camera shake and the like.

  Also, the reason for dividing the click into one click and two clicks is to distinguish the start and end of the scan, and the number of these clicks is different as long as the number is different. It doesn't matter.

  FIG. 11 is a flowchart showing a process for performing output by clicking the operation switch 22.

  When the power is turned on (step S71), the analog processing unit 46 and the code restoration processing unit 48 are started (step S72).

  Next, the controller 42 determines whether or not the operation switch 22 has been clicked (step S73). Here, when the operation switch 22 is not clicked, the determination in step S73 is repeated, and when the operation switch 22 is clicked, the processes of the analog processing unit 46 and the code restoration processing unit 48 are terminated (step S74). . Here, the data read up to the clicked time may be subjected to data reproduction processing and output without necessarily ending the processing of the analog processing unit 46 and the code restoration processing unit 48.

  Subsequently, data reproduction processing is performed (step S75), output (step S76), and this processing is terminated (step S77). In addition, you may return to a start (step S71), without ending here. Here, the data read up to the clicked time may be subjected to data reproduction processing and output without necessarily ending the processing of the analog processing unit 46 and the code restoration processing unit 48.

  The operation of the operation switch 22 according to this flowchart is particularly used when, for example, the data processing unit 4 having the analog processing unit 46 and the code restoration processing unit 48 is an AC power source or the like and does not require power saving processing. Therefore, the operator only needs to perform an output operation by clicking, the block data can be read whenever the pattern code is scanned, and only the output timing needs to be indicated.

  FIG. 12 is a flowchart showing processing for recognizing the start of pattern code scanning by providing the operation switch 22 and the bottom switch, and outputting the pattern code.

  Here, a bottom switch (BSW) (not shown) is a switch that can detect that a portion of the reading unit 2 that is in contact with the bottom of the paper surface is in contact with the paper surface, or can detect that the reading unit 2 is present on the pattern code. A switch or a switch that can detect that scanning is started, that is, a switch that recognizes that the reading unit 2 has come close to the pattern code in a readable manner. As such a switch, for example, a switch constituted by a vibration sensor, a switch for detecting pressurization, an optical switch for detecting by optical reflection on a pattern code, or the like can be considered.

  First, when the power is turned on (step S81), the controller 42 monitors the operation switch 22 (step S82), and determines whether or not the operation switch 22 is on (step S83). If the operation switch 22 is off, the process returns to step S82, and the operation switch 22 is repeatedly monitored and determined, and waits until it is turned on.

  Then, when the operation switch 22 is turned on, it is determined again whether or not the operation switch 22 is turned off (step S84). When the operation switch 22 is turned off, an output is made (step S90), and this process is terminated (step S90). Step 91).

  On the other hand, if the operation switch 22 is not off in step S84, it is determined whether or not the bottom switch (BSW) is on (step S85). If the bottom switch is not turned on, the process returns to step S84, the determination of the operation switch 22 and the bottom switch is repeated, and the process waits until the bottom switch is turned on. When the bottom switch is turned on, the analog processing unit 46 and the code restoration processing unit 48 are started (step S86).

  Next, the controller 42 determines whether or not the bottom switch is off (step S87). Here, when the bottom switch is not turned off, the determination in step S87 is repeated, and when the bottom switch is turned off, the processes of the analog processing unit 46 and the code restoration processing unit 48 are ended (step S88).

  Subsequently, a data reproduction process is performed (step S89), the process returns to step S84, and the processes after step S84 described above are performed.

  In this flowchart, the operation switch 22 is turned on, the pattern code scanning is started when the bottom switch is turned on, and the scanning is finished when the bottom switch is turned off. Since the processing in the analog processing unit 46 and the code restoration processing unit 48 is performed only during the period from when the bottom switch is turned on to off, it is possible to perform power saving processing except during scanning. Further, since the block data read by the scanning is performed when the bottom switch is turned off, that is, at the end of scanning, the data reproduction time after the operation switch 22 is finally turned off is eliminated. Therefore, it is possible to shorten the time from when the operation switch 22 is turned off until sound or an image is output.

  The data reproduction process is a process in which error correction or the like is performed on the block data obtained so far, and only those that can be corrected are transferred to the output buffer 72.

  Next, the pattern code according to the second embodiment of the present invention, which is reproduced by the information reproduction system, will be described.

  FIGS. 13A and 13B are diagrams showing a configuration example of multimedia paper used in the information reproduction system. Note that multimedia paper (hereinafter referred to as MMP) refers to a sheet on which a pattern code is recorded.

  As shown in FIGS. 4A and 4B, these MMPs 80 are composed of a picture or photograph 82, characters (text) 84, and pattern codes 86, 86a, 86b. As shown in FIG. 5B, there are codes that have a pattern code 86a in which block addresses do not overlap and codes that have an overlapping pattern code 86b.

  FIG. 14A shows one file of pattern codes.

  This file contains multimedia information composed of characters, sounds, pictures, etc., and these information can be output by one scan.

  Here, for example, it is assumed that voice information “This is a pen” is included in this pattern code. In this case, as described above, the sound “This is a pen” is output by one scan.

  However, there are cases where it is desired to repeatedly reproduce only a part of this, for example, only “This”, or multimedia information in which information such as characters, sounds, pictures, etc. is recorded, for example. The pattern code of the second embodiment for realizing these is shown in FIG. 14B and will be described below.

  As shown in the upper part of FIG. 14B, assuming that the address data of the block does not overlap, for example, “This” voice information from No. 1 to No. 50 is changed to “is” from No. 51 to No. 70. Voice information “a” is recorded from 71 to 80, and “pen” is recorded from 81 to 100.

  Thus, for example, if the numbers 1 to 50 are scanned, only the sound of “This” can be reproduced, and if the numbers 81 to 100 are scanned, only the sound of “pen” can be reproduced. If the entire image is to be reproduced, scanning from No. 1 to No. 100 may be performed at a time.

  Further, as shown in the lower part of FIG. 14B, assuming that the address data of the block is not duplicated, for example, characters from 1 to 40, characters from 41 to 80, and voices from 81 to 120 are used. Record pictures or photos before the turn.

  Thereby, for example, only characters can be reproduced by scanning from No. 1 to No. 40, and only pictures or photos can be reproduced by scanning from No. 81 to No. 120. If it is desired to reproduce the entire image, it is sufficient to scan from No. 1 to No. 120 at a time.

  That is, by arranging the block address data as non-overlapping, it is possible to reproduce only a subset which is a reproducible unit, for example, only a part of multimedia information and character information, or as a whole file. Can also be played.

  Further, the block data in the foremost column (No. 1) and the last column (No. 50) in the block data from No. 1 to No. 50 in which “This” is recorded is configured as dummy block data. Alternatively, the block data in the last column (No. 50) is arranged to overlap with the block data behind.

  Thereby, it is possible to widen an allowable range such as camera shake during scanning. In addition, block data can be captured even when the alignment of the reading unit 2 is somewhat rough during scanning.

  In addition, the letter “character” is written below the pattern codes 1 to 40 where characters are recorded, and the word “voice” is written below the pattern codes 41 to 80 where sounds are recorded. In the lower part of the pattern codes from No. 81 to No. 120 where pictures or photographs are recorded, the notation “picture (photo)” is written.

  This makes it possible to immediately reproduce only the information intended by the operator by clearly indicating what the data recorded in the pattern code is and what kind of information it is around the pattern code. Will be able to.

  FIGS. 15A and 15B are diagrams for explaining the pattern codes of the third embodiment when the pattern codes are densely arranged.

  First, it is assumed that these pattern codes shown in FIG. 15A are each a single file and are not particularly related, and are densely arranged.

  In this state, when overwriting is permitted, that is, when the block data of the address data of the most recently scanned block is fetched as block data, the adjacent pattern code is blurred at the end of scanning. Can be considered. Then, since the address data of the most recently scanned block is prioritized, block data that is not originally intended by the operator is captured, and the intended block data cannot be reproduced.

  On the other hand, in the state where overwriting is not permitted, that is, in the state where the block data of the address data of the block scanned first is fetched as block data, the pattern codes are close to each other, so that it is not intended at the time of the first scanning. A case where the pattern code is blurred is conceivable. Then, since the address data of the block that was scanned first is given priority, even if the operator recognizes a scanning error and scans again without performing an operation for output, the block is not originally intended by the operator. In some cases, data is captured and the intended block data cannot be reproduced.

  Therefore, in order to prevent the above problem, the address data of the blocks between adjacent pattern codes is configured to be the address data of non-overlapping blocks.

  FIG. 15B is an example of the pattern code of the third embodiment. When the address data of a block of a certain pattern code is No. 1 to No. 16, the address data of the adjacent lower pattern code block No. 21 through 36 are not duplicated. Also, the address data of the adjacent block of the right pattern code is set to No. 61 to No. 76 without duplication.

  That is, by allowing the address data numbers of the adjacent pattern code blocks to be different from each other even in different files, an allowable range such as camera shake during scanning can be widened.

  Next, a description will be given of a pattern code according to a fourth embodiment showing a scanning mode when a pattern code of one subset is arranged over several lines.

  Even if the pattern code is one subset and should be scanned by one scan, it may be recorded over several lines due to layout problems.

  In addition, the subset may be further separated for each information unit, and the pattern code for each information unit may be recorded over several lines. In this case, one scan is performed for one line of the pattern code. In this case, it is necessary to repeat the scanning for several lines.

  However, in both cases described above, the pattern code is visually recorded on the recording medium in the same manner, and the scanning mode cannot be determined.

  Therefore, a pattern code according to the fourth embodiment for informing the operator of the difference in scanning form will be described.

  FIGS. 16A and 16B are diagrams showing pattern codes according to the fourth embodiment.

  16A and 16B, a short convex mark 88 indicates a position where the operation switch 22 is turned on, and a tall convex mark 90 indicates a position where the operation switch 22 is turned off.

  When the pattern code of one subset described above is recorded over three lines, as shown in FIG. 16A, scanning is started from a short convex mark 88 displayed at the upper left, and the arrow Then, the scanning is advanced, and the scanning is terminated by the tall convex mark 90 displayed at the lower right.

  On the other hand, when the other subset is further separated for each information unit and the pattern code for each information unit is recorded over three lines, as shown in FIG. The operation switch 22 is turned on at the short convex mark 88 displayed on the left side to start scanning, and the scanning proceeds according to the arrow. The operation switch is displayed at the high convex mark 90 displayed on the right side of the first line. 22 is turned off and scanning is terminated. Thereafter, the process proceeds to the next line, and scanning is performed in the same manner. Note that the arrows shown in FIGS. 16A and 16B are shown on the drawing for explaining the scanning direction, and are not actually recorded on the pattern code.

  FIGS. 16C and 16D are diagrams showing pattern codes of a modification example of the fourth embodiment, and are examples in which a pattern code to be scanned is surrounded by a line.

  As a result, when the pattern code of one subset described above is recorded over three lines, scanning is performed from the upper left pattern code portion surrounded by the line 92 as shown in FIG. Start and end scanning at the lower right pattern code portion.

  On the other hand, when the other subset is further separated for each information unit and the pattern code for each information unit is recorded over three lines, as shown in FIG. Scanning is started from the left pattern code portion, and scanning is terminated at the right pattern code portion. Thereafter, the process proceeds to the next line, and scanning is performed in the same manner.

  That is, it is assumed that the pattern code surrounded by the line 92 indicates one scanning unit.

  FIGS. 16E and 16F are diagrams showing pattern codes of modifications of the fourth embodiment. The above two embodiments are combined, and the operation switch 22 is turned on / off by a convex mark 88. FIG. This is an example in which the position to be displayed is indicated by a line 92 for one scanning unit.

  As a result, the position where the operation switch 22 is turned on / off during scanning and the range to be scanned by one scanning are clarified and the operation becomes easy.

  FIGS. 17A and 17B are diagrams showing a pattern code of a modified example of the fourth embodiment, in which a logo “MMP” indicating the end of scanning is described on the pattern code.

  In the embodiment shown in FIG. 17A, scanning is started from the upper left pattern code portion, and scanning is terminated at the lower right pattern code portion in which the logo “MMP” is described. In the embodiment shown in FIG. 17B, scanning is started from the left pattern code portion of the first row, and scanning is terminated at the right pattern code portion in which the logo “MMP” is described. Thereafter, the process proceeds to the next line, and scanning is performed in the same manner.

  FIG. 17C is a diagram showing a pattern code of a modified example of the fourth embodiment. “ON” indicates a position where the operation switch is turned on / off on the pattern code, that is, “ON” indicates the start and end of scanning. This is an example of describing the logos “and“ OFF ”.

  In the embodiment shown in FIG. 17C, scanning is started from the left side of the pattern code portion in which the “ON” logo is described, and the second row in which the “OFF” logo is described. The scanning is terminated at the pattern code portion on the right side. Even in the third line, scanning starts from the pattern code part on the left side of the third line in which the logo “ON” is described, and scans in the pattern code part on the right side in the third line in which the logo “OFF” is described. End.

  FIG. 17D is a diagram showing a pattern code according to a modification of the fourth embodiment. In this example, an arrow is written around the pattern code to indicate a scanning form.

  In the embodiment shown in FIG. 17D, the scanning is performed by one scanning such that scanning is started from the upper left pattern code portion and scanning is ended at the lower right pattern code portion according to the arrow. Indicates termination.

  FIG. 18A is a diagram illustrating a pattern code according to a modification of the fourth embodiment, and “1-1”, “1-2”, and “1-3” indicating scanning forms on the pattern code. This is an example of describing a logo “”.

  In the embodiment shown in FIG. 18A, the subset is further separated for each information unit, and the pattern code for each information unit is recorded over three lines, and the left side of the first line. Scanning is started from the pattern code portion, and scanning is terminated at the right pattern code portion. Thereafter, the process proceeds to the next line, and scanning is performed in the same manner.

  FIG. 18B is a diagram showing a pattern code according to a modification of the fourth embodiment, and “1-1”, “1-2”, “1-” indicating a scanning form around the pattern code. This is an example in which the display “3” is recorded as a block code.

  In the embodiment shown in FIG. 18B, as shown in FIG. 18A, the subset is further separated for each information unit, and the pattern code for each information unit extends over three lines. Scanning is started from the pattern code portion on the left side of the first row, and scanning is terminated at the pattern code portion on the right side. Thereafter, the process proceeds to the next line, and scanning is performed in the same manner.

  FIG. 18C is a diagram illustrating a pattern code according to a modification of the fourth embodiment, and is an example in which a shape indicating a scanning form is recorded as a block code at the start and end portions of the pattern code. .

  In the embodiment shown in FIG. 18C, a pattern code of one subset is recorded over three lines. Scanning starts from the left side pattern code portion of the first line. Is completed, the process proceeds to the pattern code part on the left side of the second line. When the second line is completed, the process proceeds to the pattern code part on the left side of the third line, and the scanning is terminated at the pattern code part on the right side of the third line.

  Next, the information recording system of the fifth embodiment for forming the pattern codes of the second to fourth embodiments will be described.

  FIG. 19 is a block diagram illustrating a configuration of an information recording system according to the fifth embodiment.

  Of the multimedia information, audio information is input from a microphone or audio output device 100, amplified by a preamplifier 102, converted to digital by an analog / digital (hereinafter referred to as A / D) converter 104, and compressed. It is supplied to the processing unit 106.

  In the compression processing unit 106, the input digital audio signal is selectively supplied to a voice compression circuit 110 such as an ADPCM circuit and a voice synthesis coding circuit 112 by a switch 108.

  The audio compression circuit 110 performs data compression by performing adaptive differential PCM on input digital audio information. The voice synthesis coding circuit 112 recognizes one voice for the input digital audio information and converts it into a code. This is because the ADPCM encodes it in the form of speech information and reduces the amount of data, that is, while processing raw, it is relatively changed by temporarily changing to another synthesis code. The amount of data is reduced.

  Regarding the switching of the switch 108, for example, the user manually switches according to the purpose, for example. Alternatively, for example, a high-quality sound such as information from an audio output device is passed through the voice compression circuit 110, and for example, a voice synthesis coding circuit 112 is used for a voice or comment of a person from a microphone. It is also possible to adopt a configuration in which the audio information that has been input is recognized before and after the switch and switched automatically if it is determined in advance.

  In addition, various data that has already been formed as a digital code from a personal computer, word processor, CAD, electronic notebook, communication, etc., is first input to the data form determination circuit 116 via the interface (I / F) 114. The data form discrimination circuit 116 basically determines whether or not the subsequent compression processing unit 106 can compress the data, and some compression processing has already been performed on the data, and the subsequent compression processing unit 106. For information that cannot be obtained in the above, the compression processing unit 106 is bypassed and directly passed to the subsequent stage of the compression processing unit 106. If the input data is non-compressed data, it is sent to the compression processing unit 106. send.

  The data determined to be uncompressed code data by the data form determination unit 116 is input to the compression processing unit 106, and the code data is optimally compressed by the compression circuit 118 such as Huffman, arithmetic code, or dibrempel. Compression processing is performed. The compression circuit 118 also performs compression processing on the output of the speech synthesis coding circuit 112.

  The speech synthesis coding circuit 112 may recognize character information other than speech and convert it to speech synthesis code.

  Also, the image information of the camera, the video output device 120 and the like is supplied to the compression processing unit 106 after being amplified by the preamplifier 122 and A / D converted by the A / D converter 124.

  In the compression processing unit 106, the image area determination and separation circuit 126 determines whether the input image information is a binary image such as a handwritten character or a graph, or a natural image or the like. This image area determination and separation circuit 126 uses, for example, a discriminant image area separation method using a neural network as shown in Japanese Patent Application No. 5-163635 by the applicant of the present application, and binary image data. Separate multi-valued image data. The binary image data is compressed by a binary compression circuit 128 such as a general MR / MH / MMR as a binary compression by JBIG or the like. For multi-value image data, for example, a still image such as DPCM or JPEG is used. Are compressed by the multi-value compression processing circuit 130 using the above-described compression function.

  The data subjected to the compression processing as described above is appropriately synthesized by the data synthesis processing unit 132.

  Note that it is not always necessary to provide all of the information input and compression processing systems in parallel, and one or a plurality of systems may be appropriately combined depending on the purpose. Therefore, the synthesis processing unit 132 is not necessarily required. For the data system having only one type, it can be omitted and directly input to the error correction code adding unit 134 in the next stage. .

  The error correction code adding unit 134 adds an error correction code and inputs it to the data memory unit 136. In the data memory unit 136, each data is stored, and then an interleaving process is performed. This is a process in which continuous data strings are distributed at appropriate positions in order to eliminate errors and improve the correction capability when they are actually recorded as pattern codes and reproduced. . In other words, the task of reducing the degree of danger by using a burst error as a bit error unit is performed. The data thus interleaved is input to the modulation circuit 138. In the modulation circuit 138, for example, 8-10 modulation or the like is performed.

  In the above embodiment, it goes without saying that a code for error correction may be added after interleaving.

  After that, the marker adding unit 142 via the imaging unit 140 generates and adds a marker using a data sequence not included in the 256 data sequences associated with the modulation circuit 138. By adding the marker after the modulation in this way, there is an effect of eliminating the fact that even the marker is modulated and it is difficult to recognize it as a marker.

  The data with the marker added in this way is sent to the editing work unit 144. In this editing work unit 144, dummy block data is added to the data generated as described above, editing such as duplication of data and display of scanning units is performed, and code information as division information and Editing of recording position information, etc. is performed, and further, the data recorded on the recording paper, such as images, titles, characters, etc., is combined, converted into a data format compatible with the form of output to the printer and printing plate making, and the address It is sent to the data adding unit 146. The address data adding unit 146 adds a block address and an address error determination code (CRC or the like) to the printer system or printing plate making system 148. The data to which the address data is added is finally printed on a sheet, a tape, a printed matter, and the like by the printer system and the printing plate making system 148.

  Note that the editing operation in the editing operation unit 144 is performed by appropriately changing the code length in units of words and contents to match the page information and pattern code layout, the code dot size to the resolution of the printing machine, printer, etc. This includes editing operations such as performing, that is, changing the stage to move one row to the next line.

  The printed matter printed in this way is transmitted by, for example, the FAX 150. Of course, instead of printing the data generated by the editing operation unit 144 and having the address data added by the address data adding unit 146, it may be directly sent by FAX.

  That is, in this information recording system, after editing of code information and recording position information as division information is performed by the editing operation unit 144 and the arrangement of pattern codes is determined, the information is recorded based on the code information and recording position information. Since the address data adding unit 146 adds the address data of the block, the address data can be added so as not to overlap with the pattern codes arranged close to each other.

  FIG. 20 is a block diagram showing a configuration of an information recording system according to a modification of the fifth embodiment.

  In the configuration of this information recording system, in the embodiment shown in FIG. 19, a data editing unit 152 is added before the compression processing unit 106, and an input unit 154 is added before the data editing unit 152. Since other configurations are the same, they are incorporated here and their explanation is omitted.

  In this information recording system, multimedia information input from a personal computer, camera, microphone, etc. is determined by the data editing unit 152 as an information unit (each data length) which is the minimum output unit during reproduction. The multimedia information is divided for each information unit which is the minimum output unit at the time of reproduction, and is sent to the compression processing unit 106.

  The data input to the compression processing unit 106 is compressed for each information unit based on the editing information, which is the size data for each information unit, and an error correction code is added by the error correction code adding unit 134. Interleaving is performed in the data memory 136.

  Thereafter, processing is performed in the same manner as in the embodiment shown in FIG. 19, converted into a pattern code for each information unit, and finally printed on a sheet, tape, printed matter, and the like.

  The information unit that is the minimum output unit at the time of reproduction is, for example, a unit of a word, a phrase, or a sentence in the case of speech, and a unit whose meaning can be recognized at the time of reproduction.

  Here, in this information recording system, for example, a pattern code obtained by dividing the sound that is continuously pronounced “This is a pen” for each word of “This”, “is”, “a”, and “pen” The case of recording is described.

  The sound is input to the microphone 100 and input to the data editing unit 152 via the preamplifier 102 and the A / D converter 104. The data editing unit 152 visualizes the waveform of the sound that is continuously generated as “This is a pen”, and each waveform corresponding to the words “This”, “is”, “a”, and “pen”. The silent part between the two is recognized and divided into the above words and sent to the compression processing unit 106.

  In the compression processing unit 106, compression processing such as optimal ADPCM is performed for each information unit divided for each word, an error correction code is added by the error correction code addition unit 134, and further, the data memory 136 Interleaving is performed.

  Thereafter, processing is performed in the same manner as in the embodiment shown in FIG. 19, and each of the words “This”, “is”, “a”, and “pen” is converted into a pattern code and recorded.

  At this time, the address data of a plurality of blocks in the pattern code generated for each word is not overlapped.

  That is, by making the block addresses not overlap each other, in the information reproducing system shown in FIG. 1, the information unit visually divided by the operator, that is, the pattern code of each word is selected. It is possible to play back the continuous sound “This is a pen”, the sound of each word such as “This” only, or the continuous and partial “This is” sound, etc. it can.

  As another example, in a moving image, the information unit that is the minimum output unit at the time of reproduction is divided into several scenes, the moving image is compressed, an error correction code is added, and further interleaving is performed. The pattern code may be generated by performing the subsequent processing.

  The editing information can be input from the input unit 154, and can be automatically determined by the data editing unit 152.
