Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a learning device that controls a magnetic recording/reproducing device using control signals recorded on a magnetic tape.

Conventional Structures and Problems There are many types of learning devices that use magnetic tape, and there are a wide range of subjects and contents. Needless to say, magnetic tapes are often used in learning devices because they can be recorded and can be easily used repeatedly. Particularly in language learning, the characteristics of magnetic tape-based devices and the learning method match well, so devices that use magnetic tapes have become much more popular than devices in other learning fields. Conversation plays a large role in language learning, and it has been pointed out that Japanese people's conversational skills are inferior to their ability to translate foreign languages into Japanese. However, the reality is that foreign language conversation education through school education is not being carried out at a sufficient level due to problems with Japan's examination system. For this reason, magnetic tapes compiled in language education curricula and their recording and reproducing equipment have become widely used.

However, no matter how excellent the content of a magnetic tape is published, if the equipment used to record and play it is inconvenient to operate, it will act as a negative factor in learning and reduce the educational effect. There's no point in talking about it now. Therefore,
As for software, efforts have been made to improve the curriculum written on magnetic tape and to improve sound quality, and as for hardware, efforts have been made to improve the operability, functions, and other performance of recording and reproducing equipment. As a result, a so-called program learning machine has been proposed and put into practical use, in which a device performs predetermined operations to advance learning according to a certain calikiram.

A conventional learning device will be explained below. FIG. 1 is a diagram showing the recorded contents of the magnetic tape. In FIG. 4, 1 is a stop signal and 2 is a teaching sound. When the learner listens to the teaching audio part 2 again, or when the learner wants to listen to his or her own audio that was recorded at that time, the learner rewinds the magnetic tape drive and selects the pre-recorded audio on the magnetic tape. The learning device may automatically switch to the reproducing operation when the learning device detects the stop signal 1. However, this method has the disadvantage that, when listening to the training audio again, the learner must operate the learning device as described above. Furthermore, if the player inadvertently plays the music beyond the next stop signal, the student will not be able to play back the part he or she wants to hear over and over again, creating an inconvenience for learning.

Therefore, in order to eliminate these inconveniences, we recorded a signal after the training audio ended, and when this signal was detected, we tried to automatically repeat the playback operation, as shown in Figure 1 ( b) It is a thing.

In Fig. 1 (C), 3 is a rewind signal, and when this signal is detected during playback, the rewind operation is automatically started, and from then on, as in the case of Fig. 1 (C), the stop signal is If 1 is detected, it is sufficient to switch to playback operation. However, with this configuration, is it just 6 pages? Since it can only be learned repeatedly, there is a risk that the teaching materials are limited.In language learning, it is suitable to some extent for pronunciation practice and vocabulary learning, but it is not enough for conversation practice that requires answers. Teaching materials are difficult to prepare.

FIG. 2 shows another conventional example. This is a format in which a question with multiple choices is asked, and students are asked to choose the numbered option that they think is correct, and a message is given for each choice depending on whether the choice is correct or incorrect. In FIG. 2, 5 is a problem, and both R channels are the same. 7 is a correct answer message when the selection is correct, and 8 is an incorrect answer message when the selection is incorrect. Further, 4 is a correct answer signal containing the correct answer number, and 6 is a stop signal for stopping tape running. Both correct answer signal 4 and stop signal 6 are the same for the R channel.

FIG. 3 is a block diagram of this conventional example, where 9 and 10 are L channel and R channel magnetic heads 11 and 12, respectively.
are the L channel and R channel preamplifiers, respectively, 14
is a 7-page power amplifier that makes the speaker 16 sound. Reference numeral 13 denotes a channel changeover switch, which changes the connection between the L channel preamplifier 11, the R channel preamplifier 12, and the power amplifier 14. A signal detector 16 receives a mixture of the outputs of the L channel preamplifier 11 and the R channel preamplifier 12 as an input signal. 17 is a microprocessor, and its peripheral circuitry includes a display 18. It has a memory 19, a tape drive motor 2o, and a key switch 21, and the channel changeover switch 13 is also controlled by the microprocessor 17.

The operation of this conventional example will be explained below using FIGS. 2 and 3. When the correct answer signal 4 is detected by the signal detector 16, the microprocessor 17 stores this data in the memory 19. After problem 5 is played, signal detector 1
When the stop signal 6 is detected at step 6, the tape drive motor 20
to stop.

If there are three choices here, one will be correct and the remaining two will be incorrect. The learner inputs the number he/she thinks is correct using the key switch 21.

If the data manually entered from the key switch 21 matches the data stored in the memory 19, the microprocessor 17 determines that the answer is correct and turns the channel changeover switch 13 to L.
to drive the tape drive motor 20 and reproduce the correct answer message 7.

In addition, if the input data does not match the data in the memory 19, it is considered an incorrect answer and the channel changeover switch 13
is switched to the R side to drive the tape drive motor 20 and reproduce the incorrect answer message. This allows the learner to immediately know whether his or her answer is correct or incorrect, as well as confirm the correct answer,
By including instructions for the next career step in the incorrect answer message, the learner can easily proceed with learning because the career path he or she should take next becomes clear.

Furthermore, in the case of a correct answer, the learner can know the score status of his/her answer by adding the score to the memory 19 and outputting that value to the display 18, but even if the student answers the example question, the score is simply added. Because of this, it was difficult to know how many correct answers were given, or for how long it took to answer the questions, or where to start on page 9 of score addition, or which questions were answered correctly or incorrectly. It is not a sufficient function to be called a scoring function, and there are serious doubts as to how much it actually contributes to improving learning effects.

In addition, since the answers are always either correct or incorrect, you can proceed with learning with a quiz-like or game-like feel, so even if the learning content is a little stiff or difficult, it is easy to learn. You can never lose interest.

On the other hand, from the standpoint of emphasizing an individual's individuality, characteristics, or creativity, this question format is not desirable and may impede an individual's growth. At the same time, with this structure, it is not possible to record one's own pronunciation and then play back the recorded sounds and compare them while learning.

As mentioned above, with the conventional structure, there are cases in which the teaching materials needed to improve the educational effect are insufficient to provide them, or where learners record their own pronunciation and play it back. This has a fatal drawback in that language learning (hereinafter referred to as LL10, -ji learning) cannot be carried out by listening to and comparing the LL10 with the teaching audio.

Purpose of the Invention The present invention is a novel device that solves the above-mentioned conventional problems, and provides a learning device that is configured to fully utilize the functions of both the teaching material and the recording/playback device, thereby significantly increasing the learning effect. The purpose is to

Alternatively, by making it possible to appropriately display the unit number reviewed and the level of proficiency, the learning effect can be greatly increased.

83 and 84 are both educational voices, but 83 is an explanation or practice part, and 84 is a part corresponding to problems, questions, or the other party in a conversation.

Hereinafter, 83 will be referred to as the training practice audio, and 84 will be referred to as the training question audio. A first control signal 80 . before the teaching practice audio 83 . i! There is a second control signal 81 before the training question voice 84, but when playing back or recording page 22, the first control signal 80. Neither the second control signal 81 nor the second control signal 81 is detected, and when the third control signal after the training question voice 84 is received, the operation is switched. 8 again
5 is the part where the learner's utterances are recorded.

Next, the operation related to the present invention will be explained using FIG. 6 and FIG.

Since all control signals recorded on the magnetic tape 49 are recorded on the L channel, they are transmitted through the L channel magnetic head 50. For this reason, the L channel preamplifier 62 is always in a reproducing state, and the blank detector 69. The control signal detector 70 and the control signal demodulator are always in a state where signals can be input. magnetic tape 4
When the third control signal 82 recorded in 9 is picked up by the L-channel magnetic head 5o, it is converted into a time-series signal of "0" and 1 by the control signal demodulator 71, and then the third control signal 82 recorded in the control information decoder 72 is converted into each data.

The microprocessor 6o performs a data correctness check 23, and if it is determined that the data has been received correctly, it outputs the unit number included in the control information to the unit number display device 64 for display, and displays the unit number written in the ROM 77. Based on the switching means 77a of No. 1, the drive device 73 is switched to a state in which rewinding is performed at the position where the magnetic head contacts the magnetic tape 49, and the output of the control signal detector 7o is monitored. At the rewinding tape speed, the second control signal 81 is 400 to 700 times, so when this is detected and input to the microprocessor 6°, the second control signal 81 is switched to the drive device 73 based on the second switching means 77b.
is in the playback state, and the audio device 59 is turned on by turning on the selector switch 64 and turning off the recording amplifier 6B.
Switch to play state.

When the third control signal 82 is received again, the drive device 73 is stopped based on the third switching means 77G, and the word "PUSH" is displayed on the learning evaluation display device 63, and the corresponding unit number is displayed on the unit number display device 64. , the self-evaluation input switch display device flashes to indicate the position of the operation switch to be input. The operation switches to be input here are the progress switch 62b and the review switch 62 in the embodiment.
Equivalent to c.

When the learner presses the review switch 62c, as in the case of the first switching means, the drive device 73 is brought into a state where the magnetic heads 50, 51 are in contact with the magnetic tape 49, and the drive device 73 is put into a state where it rewinds, and the control signal detector Monitor the output of To. When the second control signal 81 is detected and the first control signal 8o is detected and inputted to the microprocessor 60, the drive device 73 is brought into the regeneration state based on the fourth switching means 77d.
Furthermore, by turning on the changeover switch 54 and turning off the recording amplifier 68, the audio device 69 is switched to the playback state. When the playback of the tape progresses and the third control signal 82 is received again, the changeover switch 64 is turned off and the recording amplifier 58 is turned on based on the sixth switching means 77e.
The audio device 59 is switched to the recording state.

In the first place, LL learning is based on recording one's own utterances in accordance with the teaching audio, and in the structure of the present invention, the unit learning begins with recording one's own utterances in accordance with the teaching practice audio 8326 pages. Don't start,
When you finish learning one unit and start learning the next unit, it is desirable to have it in recording mode.

By doing this, there is no need to make unnecessary operations or consideration for the learners, and apart from that, it is extremely convenient when making adjacent learning units related to each other and creating continuity. .

Note that when switching from the playback state to the recording state, the drive device 73 does not need to be operated because it operates in the same way in either the playback or recording state.

When the learner self-evaluates, the learner still presses the progress switch 6.
2b causes the microprocessor 60 to activate the drive device 73.
is switched from the stop state to the playback state, and the drive of the magnetic tape 49 is started. At the same time, the audio device 6 is turned off by turning off the changeover switch 64 and turning on the recording amplifier 68.
Switch 9 to recording mode and proceed to study the next unit.

The reason for switching to the recording state here is the same as the reason stated in the explanation of the sixth switching means.

Next, operation 26 regarding the learning evaluation display function.
°−1 Explain. When display switch 62 is pressed, RAM7
6, the data in the storage area 7eb for the second course selection is output to the unit number display device 64. That is, the number of the unit for which the review switch 62c is pressed is displayed during self-evaluation. This display is performed by the LED of the unit number display device 33 in FIG. For example, suppose that the career selection at the time of self-evaluation is set to "review" for units with unit numbers 1, 3, and 6. The LEDs 1, 3, and 6 of the unit number display device 33 blink. At this time, print rsTUDYJ and rREVI Ew to distinguish what unit number the flashing LED indicates, and whether it indicates the unit you are currently studying or the unit you have reviewed. (7) Both the LEDs are lit or blinking. Returning to FIG. 6 again, display switch 62,
Continue explaining what happens when you press e. When the display switch 62e is pressed, the memory area 7 of the RAM 76 for the first course selection is displayed.
6a and the data in the second career selection storage area 76b are transferred to the microprocessor 6o, and the number of "1"s (this is called the first selection number) in the first career selection memory 27 page area 76a and this data are transferred to the microprocessor 6o. The number of "1"s in the second career selection storage area 76b (
This is called the second selection number) and calculates the quotient of the addition of
Convert this into a percentage and output it. For example, if you have finished studying up to unit 6, progressed through units 2, 4, and 6, and reviewed units 1, 3, and 6, the first selection number is 3. Or the second selection number is also 3
The sum is 6 and the quotient is 0.5. This is converted into a percentage and output as a percentage of 50 to the learning evaluation display device 63. Note that this percentage will be referred to as the proficiency level. The review unit number output to the unit number display device 64 and the proficiency level output to the learning evaluation display device 63 are performed simultaneously. The same operation as described above can also be performed by receiving .

The above has been an explanation of the operation with respect to FIGS. 5 and 6. Next, the processing procedure centered on the operation of the microprocessor will be explained using flowcharts.

FIG. 7 is a main flowchart 1 of the processing procedure centered on the operation of the microprocessor in this embodiment.

In the explanation of the flowchart, each unit of processing will be called a step. In FIG. 7, step 101 indicates the start of processing, and in this embodiment, this processing is started by turning on the power. Step 102 is a process for setting the logic of the terminals of the microprocessor to the initial state, setting the value of the counter to 0, or setting the state of the memory to the initial state. Step 103 detects whether the magnetic tape 49 is correctly set on the tape drive base of the learning device, and flags the attachment/detachment of the magnetic tape 49 (in this explanation, a 1-bit flag indicating a certain state) is detected. (pointing to memory) is set to 0 or 1.

A flowchart of this step 1o3 (magnetic tape detection) is shown in FIG.

Step 104 is to input the on/off state of the switch from the terminal of the micro 29 page processor 60 after eliminating chattering occurring at the contact portion of the switch during input processing of the operation switch 62.

Step 105 determines whether a switch has been turned on based on the data input in step 104. If the switch has been turned on, the process branches to step 106 of operation switch input processing. The flowchart of this step 106 is as shown in FIG.

Step 107 is for determining whether audio control is necessary, and if necessary, the process branches to step 108. The flowchart of this step 108 is
The result will be as shown in Figure 0. Step 109 is the driving device 73
The process branches to step 110 if necessary.

In step 111, it is determined whether the selector switch (29 in FIG. 4) is in the "MICOM" position, that is, it is determined whether program learning is to be performed. If the position is "MICOM", the process branches to step 212 and below; if the position is not "MICOM", the process returns to step 103 and repeats the steps above. Go back.

Step 112 is a part for determining whether a display instruction is given, and if there is an instruction, the process branches to step 113 for display. Note that this instruction is made using the flag mentioned earlier. In step 114, it is determined whether or not the third control signal is input. If so, the process branches to step 116 and the control information is decoded. In step 116, it is determined whether or not the first or second control signal is input. If so, the process branches to step 117 to count the signals and proceed to a predetermined operation. Also, step 118 is step 11
At step 6, it is determined whether or not the decoding of the control information has been completed, and if so, the process branches to step 119 and proceeds to a predetermined operation. When these are completed, the process returns to step 103 in the same way as when the selector switch 29 is in a position other than the "MICOM" position in step 111.

FIG. 11(a) is a flowchart depicting the display step 113 in FIG. 7 in detail. In FIG. 11(a), step 166 determines whether there is a request to display the proficiency level (314-2), and if there is a display request, the data stored in the memory, for example, the progress switch (
Remember how many times you pressed 62b) in Figure 6 and how many times you pressed the review switch (62C in Figure 6), and calculate the total number of times you pressed it and the ratio of the number of times you pressed multiple switches. It is a step. Step 168 is a process of outputting the calculation result and performing a blinking display operation.

Step 169 is a process of determining whether or not it is a self-evaluation display operation, and continuing the blinking operation during the display operation. Steps 171 and 172 are steps for displaying the unit number if there is one.

FIG. 11 Φ) is a flowchart illustrating in detail step 116 of control information decoding in FIG. In step 176 of FIG. 11(b), it is determined whether the signal contains information, and if so, it is regarded as a third control signal and a command to receive the information part is issued in step 177, and the process returns to the main routine once. Return. Then again, step 175
When you go to step 17, there is a command to receive data.
At step 6, the process branches to step 178. If data has been received, it is sequentially stored in the RAM (76 in FIG. 6) (step 179). Note that this routine only receives and decodes data, and does not perform any operations using the data. FIG. 11(c) is a flowchart depicting in detail step 117 of control signal detection in FIG. In FIG. 11(c), step 182 determines whether there is an input of control signals (the first control signal and the second control signal in FIG. 6), and if there is an input, step 1 is performed.
Branch to 83. Letting N be the number of times a control signal has been detected, in step 183 the number N is increased by one.

If it is N-1 in step 184, step 18
6 and 186, set N to 0, and switch the recording/playback device to playback. In this embodiment, the operating state of the program learning is divided into six states, each of which is assigned a number from 1 to 6 and represented by a symbol LL, and the program learning is controlled by the number. This number increases as the program learning progresses, and since this step 185 also corresponds to switching the program learning (corresponding to the second switching means in FIG. 6), the value of LL increases. is increased by 1.

Step 187 branches to step 188 when N=2, and in steps 188 and 189 step 185
and 186.

Note that here as well, the value of LL is increased by 1 since this corresponds to switching of program learning (corresponding to the fourth switching means in FIG. 6).

FIG. 12 is a flowchart illustrating step 119 of the learning control in FIG. 7 in detail. In FIG. 12, steps 214 and below are particularly relevant to the present invention.
If the data type of the received third control signal is for unit control, step 214 branches to step 216 and subsequent steps. When LL is 1, the program learning is switched (corresponding to the first switching means in FIG. 6), so in step 216 the drive device 73 (FIG. 6) is switched to rewind operation, and in step 218 LL is switched to 1. increase. Also, when LI = 3, Progera 34 /'-
- In step 220, the drive device 73 (the fifth
(Fig.) is stopped, and a display prompting self-evaluation is displayed in step 221. At this time as well, in step 218 LL
Increase the value of by 1.

Next, when LL=6, the program learning is also switched (corresponding to the sixth switching means in FIG. 6), so the audio device 69 (FIG. 5) is switched to the recording state in step 223.
