DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a learning apparatus, for example, reproducing a recorded content of a recording medium on which voice data and character data for language learning, musical sound data and music data for music learning are recorded, and performing predetermined learning. The present invention relates to a learning device for performing.

[0002]

2. Description of the Related Art Conventionally, there has been known a learning apparatus for reproducing a recorded content of a recording medium on which predetermined learning data is recorded and performing predetermined learning. Most of the recording media for recording the learning data use a magnetic tape. Since the learning device using the magnetic tape reproduces the learning data in the recording order, if the learning data of the desired learning level is in the middle of the tape, the learning data is recorded at the position where the learning data is recorded. Must be found by fast-forwarding or rewinding the tape. Also, when the same learning data is repeatedly used, a complicated manual operation is similarly required. On the other hand, there is a card type recording medium on which learning data is recorded. Since the card-type recording medium has a small amount of learning data that can be recorded on one card, only learning data obtained by subdividing the content of learning is recorded on each card. Since the number of cards increases accordingly, card management becomes complicated. Learning is performed by selecting a card on which desired learning data is recorded from many cards and reproducing the selected card. In the case of the card type, since the same card can be used when learning repeatedly, there is no complicated operation like a tape type.

In order to eliminate the complicated operation of the tape type and the card type, there is a learning device described in Japanese Patent Application Laid-Open No. 63-81650 by the present applicant. According to this learning device, a rotary recording medium is used as a recording medium on which learning data is recorded. Since the rotary recording medium has a large storage capacity and allows random access, it can be easily accessed with little operation from the learning data in which a large number of voice and character data are recorded to the recording position where the desired learning data is stored. It is possible. In addition, the learning device includes a memory for temporarily storing learning data, and the learning data stored therein is used for iterative learning.
The reading speed of the learning data from the memory can be changed so that the reproducing speed of the audio data can be changed, or a display device can be provided to display character data corresponding to the output audio data. It has a function to freely program the playback order. Thus, the learning can be continued without bothering the operation of the learning device, and the learning effect can be expected to be enhanced.

FIG. 6 is a diagram showing an example of the data block index of the data block area. Here, for example, the data block index 105 is 6 digits of 10
The first two digits are the numbers of the chapters in the textbook of the learning material.
The digits represent the section number in the chapter, and the last two digits represent the syntax number in the section. Therefore, in the illustrated example, the content of the data block index 105 is “020513”, which indicates that the syntax is Chapter 2, Section 5, and Syntax 13.

The data block index has a hierarchical structure of chapters, sections, and syntax, and the movement between the hierarchies of these indices can be performed by using the playback / block advance / playback button 1
This is possible by using the button 1 and the button 12 for repetitive reproduction / return after block return. In other words, if the time for pressing the play / block forward / playback button 11 and the repetitive play / block return / playback button 12 is up to a certain length, movement within the same node is possible. The movement of the section itself, and if it is longer, the movement of the chapter.

Is represented as a 6-digit decimal number, the first two digits are fixed to 99, the middle two digits are the chapter number, and the last two digits are the number of the word in the chapter that is described by the dictionary. Defined as a number. Therefore, in the illustrated example, the content of the dictionary data block index 116 is “990423”, which indicates that the word is the 23rd word prepared for explanation in Chapter 4.

FIG. 8 is a diagram showing an example of the contents of the disk information area. The disk information includes a data block index and corresponding position data of the data reading unit 41, and a dictionary data block index and corresponding position data of the data reading unit 41. The disc information is recorded in the outermost recording area of the track of the optical disc 1.

Next, each operation of the learning apparatus 10 will be described based on the processing of the control program stored in the ROM 31. First, an operation when the optical disc 1 is mounted on the learning device 10 will be described.

FIG. 9 is a flowchart showing the flow of the operation when the optical disk is loaded. When loading an optical disc,
The disc eject button 53 is pressed, and the optical disc 1 is placed on the movable disc holder 50 that has protruded out of the outer housing by the force of the spring 51, and the movable disc holder 50 is pushed into the main body, thereby the disc insertion detection switch. It is started when 52 is turned on. When the disc insertion detection switch 52 is turned on, the current from the battery 20 is supplied to the monostable multivibrator 23 to generate a temporary voltage 23a (see FIG. 2) at its output (step S1). This temporary voltage 23a raises the power supply line 22 of the entire device through the diode 25, and the device starts operating (step S2). Then, the CPU 30 monitors the temporary voltage 23a through the diode 24 and the input interface circuit 18, and, when recognizing that this is at a high level, once turns on the power supply relay 21 through the output interface circuit 33 (step S3). At this time, when the optical disc 1 is pushed into the main body by the movable disc holder 50, the rotating shaft 43 with the flange 44 of the motor 40 is inserted into the engaging hole at the center of the optical disc 1, and the Is rotated by a disk clamper 45 rotatably provided on the opposite side.
And is rotatable integrally with the rotating shaft 43.

Next, the CPU 30 issues an instruction to the head position control mechanism section 42 to move the data reading section 41 so as to be located substantially at the outermost periphery of the optical disk 1 on which the disk information is recorded. To start the rotation of the optical disk 1 (step S4). At this time, the data reading unit 41 emits a laser beam, and while the return light reflected from the optical disc 1 is detected, feedback is also applied to the head position control mechanism unit 42 so as to obtain optimal data.

Next, the data reading section 41 reads disk information on which a number of data block indices and position data of the data reading section are recorded from the outermost peripheral portion of the optical disk 1, and an index head position storage section 61.
(Step S5). When the signal at the end of the disc information is detected, the operation of reading and storing the data is stopped. Further, the index storage unit 64 stores the smallest index number from the detected disk information.

At this stage, a timer (not shown) is started and it is monitored whether there is any operation input within a predetermined time (step S6). Here, when the timer times out without any operation input, the data stored in the index head position storage unit 61 and the index storage unit 64 and the type of language to be reproduced / displayed are set to the default B. Data is EEPROM 32
And the power supply relay 21 is turned off (step S
7). If any of the buttons is pressed within a predetermined time and there is any operation input, a process corresponding to the operation input is started (step S8).

FIG. 10 is a flowchart showing the flow of the operation during normal reproduction of the optical disk. The operation during normal playback is
When the playback / playback button 11 is momentarily pressed after the playback / block advance, the current of the battery 20 is directly supplied to the power supply line 22 through the diode 11b,
Rises momentarily, and is reproduced by the CPU 30 through the input interface circuit 18 via the diode 11a.
The process is started by notifying that the reproduction / combination button 11 has been pressed after the block advance. When the CPU 30 detects that the reproduction / playback button 11 has been pressed after the reproduction / block advance, the CPU 30 drives the power supply relay 21 via the output interface circuit 33, and keeps the power supply relay 21 on unless otherwise instructed by the CPU 30 ( Step S1
1).

Play / block advance and play after playback button 1
CPU 30 that has detected that button 1 has been pressed for a moment
The last play index in the ROM 32 is read, and the index number is stored in the index storage unit 64.
And the position data of the data reading unit 41 corresponding to the index number is continuously stored in the EEPROM.
32, and supplies the position data to the head position control mechanism section 42 through the output interface circuit 33 (step S12).

Next, the head position control mechanism unit 42 moves the head of the data reading unit 41 to a position immediately before a data block having a predetermined index number exists, and
Subsequently, 30 issues an instruction to the motor 40 to start the rotation of the optical disk 1, the data reading unit 41 reads the data recorded on the optical disk 1, and inputs the output to the index match determination unit 62 (step S13). The index match determination unit 62 is provided with an index number to be determined for match from the index storage unit 64 in advance, and when the index number matches the index number of the read data, all of the data blocks represented by the index number thereafter are read. Is transferred to the subsequent data type determining / distributing unit 65 (step S14). Subsequently, the data type discriminating and distributing unit 65 outputs the data start identifiers 112 and 11 indicating the start of each data shown in FIG.
In accordance with 3, 114, and 115, A language voice data 109, B language voice data 110, A language character data 106, B language character data 107, and dictionary pointer correspondence index 108 of a given data block area 101 are respectively A language voice demodulated. The data is transferred to the unit 67, the B language voice demodulation unit 68, the A language character temporary storage unit 69, the B language character temporary storage unit 70, and the dictionary pointer correspondence index temporary storage unit 66 (step S15).

If the data type is voice, demodulation and temporary storage of voice data are performed (step S16). That is, the A-language audio data 109 and the B-language audio data 110 are demodulated by the A-language audio demodulation unit 67 and the B-language audio demodulation unit 68, respectively. 73 is stored.
The addresses of the A-language temporary voice storage unit 72 and the B-language temporary voice storage unit 73 are connected to a clock counter (not shown). Immediately after data storage starts, this counter starts counting, and the stored data is read out. First, the output is guided to the data selector / end sensor unit 74.

Here, the data selector / end sensor unit 74 determines which language of the sound to be reproduced from the data read from the EEPROM 32 by the CPU 30.
, The audio data of either the selected A language or B language is selected and output, and this output is converted into an analog signal by the D / A converter 76,
The sound is reproduced by the earphone 79 via the volume adjustment unit 77, the amplifier 78, and the earphone terminal 7 (step S17).
Note that data indicating the end is added to the end of the audio data. When the data selector / end sensor unit 74 obtains this data, it notifies the CPU 30 of the data.

On the other hand, when the data type is character, the character data passed from the data type determining / distributing section 65 is temporarily stored (step S18). Next, the data stored in the A-language character temporary storage unit 69 and the B-language character temporary storage unit 70 are stored in the EEFROM 32 in accordance with the data of which language the character should be displayed. The character in the language of the type selected by the unit 75 and stored in the display temporary storage unit 80 according to the data is displayed on the character display unit 6 (step S19).

Thereafter, it is determined whether or not there is an instruction from the operation button (step S20). If there is no instruction from the operation button, it is determined whether or not the data block is the last (step S21). Return the last play index to the initial state and set it to E
After storing the data in the EPROM 32, the power supply relay 21 is disconnected. If it is not the last, the process returns to step S12 and the CPU 3
0 reads the next index number from the EEPROM 32, passes the number to the index storage unit 64, stores the index number in the EEPROM 32 as the last play index, issues an instruction to the head position control mechanism unit 42, and the data reading unit 41 The reading of the data block of the number is started, the data block of the next index number is fetched in the same manner as described above, and the reproduction of the voice in the designated language and the display of characters are continued. If there is any instruction from the operation button,
The process jumps to a process according to the operation instruction (step S22).

Next, FIG. 11 shows a pattern in which the audio signal can be reproduced without interruption in the above-described audio data processing. FIG. 11 is an explanatory diagram of continuous reproduction of a plurality of audio signals. The CPU 30 determines that the data block start identifier 104 represents the beginning of the data block, the data block index 105, the A language character data 106, the B language character data 107, and the dictionary pointer corresponding index 10
8 is read from the optical disc 1, the data type is determined, and the audio data obtained by demodulating the A-language audio data 109 and the B-language audio data 110 is stored in the corresponding temporary storage unit. It is ready to play regardless. When the A-language audio data 109 and the B-language audio data 110 are read from the optical disc 1, each audio data is immediately demodulated and reproduced, so that the reproduced audio is not interrupted.

Next, a description will be given of the operation when the reproduction / block advance and reproduction / playback button 11 is pressed. FIG. 12 is a flowchart showing the flow of the operation when the reproduction / button is pressed after the reproduction / block advance. First, during stop or playback, it is determined whether the playback / block advance and playback combined button 11 has been pressed for a moment, for example, a time of 0.2 seconds or less (step S31). If so, the normal reproduction shown in FIG. 10 is performed (step S32). Next, the pressing time of the reproduction / button 11 after reproduction / block advance is set to, for example, 0.2-0.4.
It is determined whether or not the time is seconds (step S33). If the pressing time is 0.2-0.4 seconds, the CPU 30 detects this and presses the next index of the index number in the index storage unit 64. The number is checked from the data in the EEPROM 32, and the number is stored in the index storage unit 6.
4, the last play index in the EEPROM 32 is rewritten, and the head position control mechanism 42 is instructed to set a position where the data block of the index number can be read, and the data of the index number is read in the same manner as described above. The syntax of the block is fetched, and the display of the characters in the designated language and the reproduction of the sound are continued (step S34).

Next, it is determined whether or not the reproduction / block advance and reproduction / playback button 11 has been pressed for 0.4-0.6 seconds (step S35). Specifies the next index number next to the last play index in the EEPROM 32 in the same manner,
The CPU 30 controls to reproduce the corresponding syntax (step S36).

Next, it is determined whether or not the playback / block forward / playback button 11 has been pressed for 0.6-0.8 seconds (step S37). Specifies the next index number next to the last play index in the EEPROM 32, and controls the CPU 30 to reproduce the corresponding syntax (step S38).

Further, it is determined whether or not the reproduction / block advance and reproduction / playback button 11 has been pressed for 0.8-1.1 seconds (step S39).
In the case of seconds, the CPU 30 controls to specify the index number of the first syntax in the section following the last play index in the EEPROM 32 and to perform reproduction (step S40).

In addition, it is determined whether or not the playback / after-playback button 11 has been pressed for 1.1-1.5 seconds (step S41).
In the case of seconds, the CPU 30 specifies an index number of the first syntax in the first section of the next chapter of the last play index in the EEPROM 32, and controls the CPU 30 to perform reproduction (step S42).

Play / block forward / playback button 1
If the pressing time of No. 1 exceeds 1.5 seconds, it is determined whether or not the pressing is completed (step S43), and further, it is determined whether or not the next chapter is the last (step S44).
If it is not the last chapter, the number of the chapter to be specified is incremented (step S45), the index number of the first syntax of the first section of the next chapter of the last play index in the EEPROM 32 is specified, and reproduction is performed. CPU 30
Performs control (step S46), and returns to step S43.

When all the data blocks have been reproduced, the CPU 30 returns the last play index to the initial state, and stores it in the EEPROM 32.
The power supply relay 21 is disconnected (step S47).

As described above, the syntax, the section or the chapter is designated and the reproduction is performed according to the length of time during which the reproduction / button 11 is pressed after the reproduction / block advance.
By changing the ROM 31 containing the contents of the software of U30, the reproduction / block advance / after-playback button 11 is pressed once and the next syntax is reproduced. Press the key once more to repeat the next syntax, press four times to play the first syntax of the next section, and press it five times to play the first syntax of the first section of the next chapter. It is also possible.

Next, the operation when the reproduction / button 12 is pressed after the repeated reproduction / block return will be described. FIG. 13 is a flowchart showing the flow of the operation when the repetitive reproduction / block return / reproduction / playback button is pressed.
First, it is determined whether the playback / return / playback button 12 is pressed for a moment, for example, 0.2 seconds or less, during stop or playback (step S5).
1) If the pressing time is 0.2 seconds or less, the CPU 30 controls the peripheral blocks in the same manner as described with reference to FIG.
The data block indicated by the last play index in the EEPROM 32 is reproduced and stopped (step S).
52). Thereafter, it is determined whether or not there is a button operation within a certain time (step S53). If the button 12 is pressed again within a certain period of time after the end of the playback, the optical disc 1 is again pressed.
The CPU 30 performs the reproduction using the data in the A-language voice temporary storage unit 72, the B-language voice temporary storage unit 73, the A-language character temporary storage unit 69, and the B-language character temporary storage unit 70 without reading the data. Control. If there is no button operation within a fixed time after the end of the reproduction, the data in the index storage unit 64 is stored in the EEPROM 32 as the last play index, and the power relay 21 is turned off (step S54).

In a similar manner to the case of the forward playback after block advance of the disc, it is next determined whether or not the button 12 for repeated playback / return after block return has been pressed for 0.2-0.4 seconds (step S55). , Press time 0.2-
In the case of 0.4 seconds, the data block indicating the syntax immediately before the last play index in the EEPROM 32 is reproduced (step S56), and the process proceeds to step S53.

It is also determined whether or not the button 12 has been pressed for 0.4-0.6 seconds after the repeated playback / block return (step S57).
If it is 0.6 seconds, the syntax immediately before the last play index in the EEPROM 32 is reproduced (step S).
58).

It is determined whether or not the reproduction / button 12 is pressed for 0.6-0.8 seconds after the repeated reproduction / block return (step S59). Is reproduced three steps before the last play index (step S60).

Also, it is determined whether or not the reproduction / button 12 is pressed for 0.8-1.1 seconds after the repeated reproduction / block return (step S61).
If it is 1.1 seconds, the first syntax of the section before the last play index is reproduced (step S62).

Further, it is determined whether or not the reproduction / button 12 is pressed for 1.1-1.5 seconds after the repeated reproduction / block return (step S63).
If it is 1.5 seconds, the first section and the first syntax of the chapter before the last play index are reproduced (step S64). If the button is pressed for 1.5 seconds or more, the first section and the first syntax of the chapter two before the last play index are reproduced and stopped (step S65). If the pressing time exceeds 1.5 seconds, chapters may be sequentially returned to the first chapter as needed.

Also in this case, by changing the software stored in the ROM 31, the same function can be provided by the number of times the reproduction / playback button 12 is repeatedly pressed after repeated reproduction / block return.

Next, the operation when the audio language type selection button 14 and the display language type selection button 13 are pressed will be described. When the voice language type selection button 14 is pressed while the power relay 21 is on, the CPU 30 is notified via the input interface circuit 18. When the CPU 30 detects that the speech language type selection button 14 is pressed, the CPU 30 outputs an instruction to switch the speech language type to the data selector / end sensor unit 74. In response to this instruction, the data selector / end sensor unit 74 determines whether the audio data to be output to the D / A converter 76 is to be output from the A-language audio temporary storage unit 72 or to the B-language audio temporary storage unit 73. Make an input selection. Thereby, the voice of the selected voice language type can be output from the earphone 79.

When the display language type selection button 13 is pressed, the CPU
30 is notified. When the CPU 30 detects that the display language type selection button 13 is pressed, the character data selector 75
An instruction to switch the display language type is output to the CPU. In response to this instruction, the character data selector 75 switches the display language type. As a result, the character data of the switched display language is output from the character display unit 6.

Next, the operation of the dictionary function of the learning device 10 will be described. As shown in FIG. 5, a special code called a dictionary pointer is added to the character data in addition to a normal character code and a blank code. The dictionary pointer is located just before the first character code of a word that is difficult compared to the level of the learner, indicating that it is a dictionary pointer, and indicating the order of the pointer in the syntax. Have.

When reproducing the character data of the data block indicated by the last play index in the EEPROM 32, the character data selector 75 selects one of the character data in the A character temporary storage section 69 or the B character temporary storage section 70. Then, the data is stored in the display temporary storage unit 8.
In this case, the dictionary pointer is also stored in the display temporary storage unit 80.

Here, the CPU 30 retrieves the rank data from the dictionary pointer rank memory 81 and gives it to the display temporary storage section 80. The display temporary storage section 80 receives the rank represented by the dictionary pointer and gives it from the CPU 30. A code is generated that underlines a word that matches the rank given. Based on the code, a syntax in which only one word is underlined appears in the character display unit 6.

Here, by pressing the underline move buttons 15 and 16, the value of the dictionary pointer rank memory 81 is moved up and down, and finally the learner can underline words that he does not know well.

When the learner presses the dictionary function selection button 17 after underlining a certain word in this way, the CPU
30 is a dictionary pointer corresponding index temporary storage unit 66 according to the number of the dictionary pointer order memory 81,
The corresponding index is selected, and the index data is stored in the dictionary data block using the index head position storage unit 61, the head position control mechanism unit 42, the data reading unit 41, the index storage unit 64, the index match determination unit 62, the data type determination distribution unit 65, and the like. The contents of the area 102 are stored in the dictionary character temporary storage unit 71, provided to the display temporary storage unit 80 through the character data selector unit 75, and finally the contents can be displayed on the character display unit 6. When the dictionary function selection button 17 is pressed again, the data in the A character temporary storage unit 69 or the B character temporary storage unit 70 is displayed on the character display unit 6.

In this embodiment, the dictionary data is character data. However, the dictionary data may include voice data. In this case, a voice demodulation unit and a voice temporary storage unit are added for dictionary data, and the voice language type selection button is a button for switching three types of voice data.

[0065]

As described above, according to the present invention, the data block read by the reading means is stored in the temporary storage means, and the data retrieving means retrieves the voice data selected by the voice data selecting means. The voice data selecting means is provided independently of the symbol data selecting means. As a result, it is possible to enhance the learning effect on the learning of music in which, for example, music that does not include the sound of the vocal part and music that does include the vocal part are alternately repeatedly heard or sung. In addition, it is possible to perform advanced learning such as reading characters of the language B while listening to the language A, and also speaking the language B. Further, the index designating means designates the index sequentially or for each predetermined classification unit, and furthermore,
Since the designation can be performed in the ascending order or the reverse order of the index, the transition to the target learning data can be easily performed only by the index specifying means, and the continuation of the learning is hardly hindered.

Further, the index designating means has a function for turning on the power, and a release means for turning off the power after a predetermined period of time after the end of a certain application is provided, thereby eliminating the troublesome operation of turning on and off the power. Can concentrate on learning and enhance the learning effect. Accordingly, if there is no operation for a predetermined time or more, the power is automatically turned off, so that when the learning device is a battery-driven portable type, the life of the battery can be extended.

Further, a nonvolatile storage means is provided, in which an index designated by the index designating means is stored, and when the power is turned on, a data block designated by the index stored in the nonvolatile storage means is read. Since the means is read out, the learner does not need to remember how much he / she has learned in the previous learning, and can immediately learn the continuation, so that the learning effect can be enhanced.

Further, the second data block including voice data or symbol data related to specific symbol data of the first data block can be reproduced. Thereby, when the dictionary data is recorded on the rotary recording medium as the second data block, a word unknown to the learner is included in the characters displayed on the display means based on the symbol data of the first data block. When there is a word, by performing a simple operation of designating the word by the selection instructing means and instructing it by the related data use instructing means, the meaning of the word is read out from the second data block and output as voice or character. It can be displayed and the trouble of checking the meaning using a dictionary can be omitted, so that the learning effect can be significantly improved.
