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 learning methods closely match, making them far more popular than in other learning fields. Conversation is a very important part of language learning, but 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 conducted at a sufficient level due to problems with Japan's first examination system. For this reason, magnetic tapes compiled in language education curricula and their recording and reproducing equipment are widely used and utilized.

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 effectiveness of teaching. There's no need to talk about it now. Therefore,
In terms of software, efforts have been made to improve the curriculum written on magnetic tape and to improve sound quality, and in terms of hardware, efforts have been made to improve the operability and reliability of recording and playback equipment. As a result, so-called program learning machines have been proposed and put into practical use, in which devices perform predetermined operations to advance learning according to a fixed curriculum.

It's just a simple study of a specific unit.
Many ideas have been proposed to make it easier to repeat learning by reading sentences one by one. Among these, the latter function of repeated learning of sentences has become so popular that it is becoming increasingly regarded as an essential feature of LL learning devices, regardless of whether they are at a high or low level. The most common method for implementing the sentence repetition function is to detect blank spaces between sentences. (Note that this blank area is simply an area where no signal is recorded.

) However, strictly speaking, there are blank spaces outside of sentence spacing, such as between words or between sentences, and if we are to distinguish them from blank spaces between sentences, they are generally considered to be Since the blank spaces in between are just longer, the accuracy in detecting blank spaces tends to be lacking.

Therefore, in order to improve detection accuracy, a specific signal, for example, a 60Hz sine wave (specific signal), is recorded in advance between sentences, and detection is performed by detecting the specified signal as described in "2" when rewinding the magnetic tape. .

However, while the above-mentioned method for detecting spaces between sentences can be used with any educational material as long as there is no concern about the accuracy of the detection, the latter method for detecting specific signals requires a detection method. The recording/playback device and the magnetic tape on which specific signals are recorded must be used as a set.

The configuration of the conventional example will be described below. In addition, from the standpoint that the method of blank detection or specific signal detection described in Section 1 is not the essence of the present invention, but only a difference in general embodiments, the following conventional examples will focus on methods using blank detection only. Explanation: Figure 1 shows the recorded contents of the magnetic tape, numbers 2 and 4 each record audio for teaching in units of sentences, and numbers 1 and 3 are blank areas between sentences.

In order to repeatedly learn a sentence, blank portion 1 is detected when the sentence is at the position of sentence 2, and blank portion 3 is detected when the sentence is at the position of sentence 4.

FIG. 2 is a block diagram showing the configuration of a conventional example. 8 is a magnetic tape, 9 and 1o are magnetic heads for the L channel and R channel, respectively, 11 and 12 are preamplifiers for the L channel and R channel, respectively, and 14 is a power amplifier for making the speaker 15 sound. Further, reference numeral 13 denotes a channel changeover switch for switching the connections between the L channel preamplifier 11, the R channel preamplifier 12, and the power amplifier 147. 16 is a blank detector which uses the output of the L channel preamplifier 11 as an input signal. 22 is a recording microphone, and 23 is a recording amplifier. Reference numeral 17 denotes a microprocessor, and its peripheral circuits include a display 18, a memory 19, a tape drive motor 20, and a key switch 21, and the channel changeover switch 13 is also controlled by this microprocessor. In addition,
In the following explanation 1, unless otherwise specified, "playback" refers to the state in which both the R channel and the R channel are being played back, and "recording" refers to the state in which the L channel is being played back and the R channel is being recorded.

FIG. 3 is a flowchart 1 showing the flow of operations regarding repeated sentence learning (hereinafter referred to as sentence repeat) in this conventional example. The operation will be explained with reference to FIG. 3 while also referring to FIG. Step 252 is a part for checking whether a certain repeat key (not particularly shown) in the key switch 21 has been pressed. If there is an input, the process moves to step 253. In step 253, the tape drive moke 20 is first reversed to bring the magnetic tape 8 into a rewinding state. When this setting of the rewind state is completed, the process moves to the next step 254. In step 264, the microprocessor 17 constantly monitors the output of the blank detector 16, and if there is an output, the process moves to the next step 255. It should be noted that the blank detector is composed of a comparator (not shown) and a timer (not shown), but since these are common, their explanation will be omitted.

When a blank area on the magnetic tape 8 is detected, in step 255, the tape drive motor 20 is rotated in the normal direction, and the R channel preamplifier 12 and the recording amplifier 23 are placed in a reproducing state. In addition, at this time, L channel preamplifier 1
1 is, of course, regeneration. With this, the sentence repeat is completed, and the learner plays back the teaching audio and the audio that he or she has generated and recorded, and listens to and compares the results. This is useful only when you want to listen to the training audio repeatedly or when you want to compare and evaluate the training audio with the audio you have recorded, and cannot be used when recording. This is because it is difficult to accurately switch between recording and playback with a purely mechanical recording and playback device that uses human operating force as the driving force for levers and switches. Since there is no playback control, erroneous erasure may occur, making it difficult to achieve this goal. Therefore, if a learner makes a recording mistake or immediately realizes that his/her own voice is not good during the recording and wants to re-record, the student can switch to playback mode, locate the beginning of the sentence, and then switch back to recording mode. The operation was extremely inconvenient because it had to be switched.

Furthermore, even if this procedure is automated, the conventional method only locates the beginning of the sentences recorded in the teaching channel, that is, the L channel, and the channel that the learner recorded by speaking, that is, the R channel. It wasn't something to cue up. However, in the above case, if the teaching material is in the form of questions, if it is in a practice format that mixes listening and dictation, or if explanatory text is inserted, it may be difficult for the learner to pronounce the utterance. This function could have the opposite effect on learning, as the beginning of the sentence would be located regardless of the part of the sentence. Furthermore, since the recording starts abruptly after the beginning of the sentence, learners may lose the timing of their utterances, resulting in insufficient pronunciation or making mistakes in the content of the conversation. It was something that was missing.

Purpose of the Invention The present invention solves the above-mentioned conventional problems.After finding the beginning of a sentence using sentence repeat, the means for switching to recording can be changed to a teaching track or used by the learner for recording, depending on the type of teaching material. It enables a learning method in which you select one of the tracks and use the recording signal of that track to cue the beginning of the sentence and then switch to recording.Also, the beginning of the sentence is played back from one sentence before the part to be recorded, and the recording is performed. By switching to recording from the part you want to record,
It is an object of the present invention to provide a learning device that enables learning that allows sufficient mk of context, and that can significantly improve learning effects by realizing a completely new learning format.

Structure of the Invention The present invention includes means for rewinding the magnetic tape while detecting signals recorded on the magnetic tape, and track selection means capable of externally specifying the track for the signal detection. and a means for canceling the rewinding state and switching to the recording state when a blank part of the magnetic tape or a specific signal continues for a certain period of time or more during the rewinding of the track. By providing a means for selecting a blank area or a track where a specific signal is detected, and switching to recording after finding the beginning, various teaching materials can be used effectively, and this can greatly contribute to improving the learning effect.

In addition, by providing a means to switch to recording when a blank area during cueing or when a specific signal is detected twice, the context can be fully recognized and learning can be done with more time, resulting in more effective learning. It is intended to improve the

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. There is a first control signal 80 before the training practice audio 83, and a second control signal 81 before the training question audio 84. During playback or recording, the first control signal 80 and the second control signal are 81 are not detected, and when the third control signal after the training question voice 84 is received, the operation is switched. Further, 86 is a recording portion of the learner's utterances.

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 5o. For this reason, the L channel preamplifier 52 is always in a reproducing state, and the control signal detector 70 and control signal demodulator are always in a state where signals can be input. When the third control signal 82 recorded on the magnetic tape 49 is picked up by the L channel magnetic head 60, the control signal demodulator 71 outputs "O".
"," and "1", and the control information decoder 72 converts them into respective data.

The microprocessor 6o checks the correctness of the data, and if it is determined that the data has been received correctly, the unit number included in the control information is output to the unit number display device 64 for display, and is written in the ROM 77. First switching means 77
Based on a, the drive unit 73 causes the magnetic head to move the magnetic tape 4.
Switch to rewinding state at the position touching 9 and control.
The output of signal detector 70 is monitored. Since the second control signal 81 has a frequency of 400 to 700 Hz at the tape speed of rewinding, this is detected and inputted to the microprocessor 60, and the drive device 73 is placed in the playback state based on the second switching means 77b, and the switching is performed again. By turning on the switch 54 and turning off the recording amplifier 68, the audio device 59 is switched to the playback state.

When the third control signal 82 is received again, the drive device 73 is stopped based on the third switching means 77C, and the learning evaluation display device 63 displays, for example, the words "°'PUSH".
The unit number display device 64 blinks to display the corresponding unit number and the position of the operation switch to be input to the self-evaluation input switch display device. The operation switches to be input here are the progress switch 62b and the review switch 6 in the embodiment.
Corresponds to 2c.

When the learner presses the review switch 62c, as in the case of the first switching means, the drive device 73 is put into a state where it rewinds at the position where the magnetic tape 49 is in contact with the magnetic tape 49, and the control signal detector Monitor the output of 70. When the second control signal 81 is detected and the first control signal 80 is detected and inputted to the microprocessor 6o, the drive device 73 enters the regeneration state based on the fourth switching means 77dVc.
, the audio device 59 is switched to the playback state by turning on the changeover switch 54 and turning off the recording amplifier 58. When the playback of the tape progresses and the third control signal 82 is received again, the changeover switch 54 is turned off and the recording amplifier 58 is turned on based on the fifth switching means 77e, thereby switching the audio device 59 to the recording state. .

In the first place, LL learning is based on recording one's own vocalizations in accordance with the training audio, and even in the configuration of the present invention, the unit learning begins with recording one's own vocalizations in accordance with the training audio 83. Therefore, it is desirable to have the recording mode on when you finish studying one unit and start studying the next unit. By doing this, there is no need to make unnecessary operations or considerations for the learners, and apart from that, it is possible to create relationships between adjacent learning units,
This is extremely convenient when 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.

Also, when the learner self-evaluates, the learner can press the progress switch 6.
2b causes the microprocessor 60 to
3 from the stop state to the playback state, and the magnetic tape 49
start driving. At the same time, turn off the selector switch 54,
By turning on the recording amplifier 58, the audio device 69 is switched to the recording state, and the learning of the next unit proceeds. The reason for switching to the recording state here is the same as the reason stated in the explanation of the fifth switching means.

Next, the operation of sentence repeat will be explained.

During learning, stop switch 62d or display switch 62e
When the microprocessor 60 presses the button, the microprocessor 60 stops the drive device 73. Additionally, in order to store the state of the audio device 59 at this time, that is, whether it is playing or recording, the state is stored in the RAM 76. Next, when the learning start switch 62a is pressed, the microprocessor 60 switches the drive device 73 to rewind with the L channel magnetic head 50 in contact with the magnetic tape 49. However, rewinding may not be possible if the audio device 59 remains in the recording state due to reasons such as the unsteady rewinding speed, unstable head touch, or track misalignment. Double recording,
Uneven erasing.

Otherwise, it may cause phenomena such as demagnetization of adjacent tracks, so it is necessary to keep it in a state other than recording, in a state in which there is no output from the amplifier, or during playback. For this reason, when rewinding the magnetic tape 49, the microprocessor 5 60 switches the audio device 69 to the playback state.

Blank detection can only be performed when these conditions are met.

The switch state of the trunk selection switch 79 at this time,
That is, either the L channel preamplifier 52 or the R channel preamplifier 53 is connected to the blank detector 69 depending on whether the learner has selected the L channel or the R channel. When a no-signal portion on the magnetic tape 49 continues for a certain period of time or more, for example, one second or more in terms of playback time, the blank detector 69 outputs an output. This output is input to the microprocessor 60, which causes the microprocessor 60 to switch the drive device 73 into the regeneration state. At this time, based on the recording or playback state stored in the RAM 76, if the storage is recording, the microprocessor 60 switches the audio device 59 to the recording state. Also, when the memory is being played back, the state is switched to the playback state.

Although the important part or the reproduction part is controlled by the microprocessor 60 as the program learning progresses, the above-mentioned sentence repeat operation is the same regardless of the part of the program learning. However, after detecting the end of the magnetic tape 49 or when displaying to evaluate learning, sentence repeat is not necessary, or may even be inconvenient for learning, so a program is stored in the ROM 77 in advance. In the above case, the microprocessor 60 omits the sentence repeat operation.

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 of the processing means centering 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 the second 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 placed on the tape drive base of the learning device by detecting the magnetic tape 49.
9 is attached/detached, a flag (in this explanation, it refers to a 1-bit memory indicating a certain state) is set to O or 1.

A flowchart of this step 103 (magnetic tape detection) is shown in FIG.

Step 104 is to input the on/off state of the switch from the terminal of the microprocessor 60 after removing chattering occurring at the contact portion of the switch in the 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. A flowchart of this step 106 is shown in FIG.

Step 107 is for determining whether or not audio control is necessary. 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.

Step 111 determines whether the selector switch (29 in FIG. 4) is in the "MICOM" position. In other words, it is a decision as to whether or not it is program learning. If the position is "MICOM", the process branches to step 212 and subsequent steps; if the position is other than "MICOM", the process returns to step 103 and repeats the above steps.

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 115 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 5, it is determined whether or not the decoding of the control information has been completed, and if it has been completed, 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. 9(a) is a flowchart depicting step 106 in FIG. 7 in detail. In FIG. 9(a),
Steps 128 and 129 are the selector switch 29 (
4) is operated, the drive device is stopped to avoid discrepancies in recording tracks between LL learning (LL) and normal tape recorder (N'QRMAL) usage, or confusion in program learning. It is for. In step 130, it is determined whether the selector switch 29 is in the ``MICOM'' position or in any other position, and the operation of each switch is distributed.

In the case of "MICOM", the operation is assigned to the operation corresponding to each switch in the program learning operation switch group 31 in FIG. This is from step 131 to step 1 for each operation of learning start, stop display, progress or review.
This corresponds to each step up to 40. ”IVIIC
In cases other than OM'''', the operations are similarly assigned to the operations corresponding to the general operation switch group 30 in FIG. 4.

This is a playback, recording 2 pause, fast forward 2 rewind or stop operation, from step 141 to step 152.
Each step corresponds to this.

FIG. 9(b) is a flowchart showing in detail the operation of the learning start switch in step 132 in FIG. 9(a). Step 302 is a judgment as to whether or not the end of the magnetic tape 49 (FIG. 4) has been detected.
Step 3 determines whether or not the score has been displayed during program learning as described above. If so, the process branches to step 304 and switches to the recording operation without performing the sentence repeat operation. In cases other than those just described, the process is subject to sentence repeat, so the process proceeds to step 305 and subsequent steps.

Step 30.6 is a step in which the audio device 59 (FIG. 4) is released from the recording state in order to eliminate the inconvenience caused by unstable running of the magnetic tape during rewinding as described above. Step 306 involves rewinding the drive unit 73 (FIG. 4) for sentence repeat and storing the recording or playback status in the RAM 76 (
(Fig. 4). After completing the above tasks, microprocessor 60 begins monitoring the output of blank detector 69 in FIG. This is step 307
corresponds to When a blank space is detected in step 307, the process advances to the next step 308. Here, it is checked whether the state stored in the RAM 76 in step 306 is recording or playback, and if it is recording, the process branches to step 304 and the drive device 73 and audio device 69
Switch to recording mode. If it is still in the playback state, the process branches to the step 309 and switches to the playback state in the same way.

FIG. 11(a) is a flowchart depicting the display step 113 in FIG. 7 in detail. In FIG. 11(a), step 166 determines whether or not there is a request to display the proficiency level. If there is a request to display the proficiency level, if there is a request to display the proficiency level, the progress switch (62b in FIG. If you press the review switch (5th
This is a step in which the number of times 62C) in the figure is pressed is memorized and the ratio of the total number of times the switch is pressed and the number of times the repeat switch is pressed is calculated. Step 168 is a process of outputting the calculation result and performing a blinking display operation. Step 1
Steps 171 and 1 are steps 69, which determine whether or not it is time to display self-evaluation, and continue blinking during the display operation.
72 is a step of displaying a unit number if there is one.

FIG. 11(b) is a flowchart illustrating in detail step 116 of decoding the control information in FIG. 11th
In Figure (b), step 176 determines whether the signal contains information, and if so, it is regarded as a third control signal, and step 177 issues a command to receive the information portion, and then returns to the main routine. . Then again, step 17
When you get to step 5, there is a command to receive data, so go to step 1.
At 76, 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 showing step 117 of control signal detection in FIG. 7 in detail. In FIG. 11(c), step 182 determines whether a control signal (the first control signal and second control signal in FIG. 6) is input. If there is an input, the process branches to step 183. 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
Branch to 5 and 186, set N to ○, 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 2 and represented by a symbol LL, and the program learning is controlled by the number. This LL
will be called the progress counter. The number increases as the program learning progresses, and at step 185 the program learning is switched (sixth step).
(corresponding to the second switching means in the figure), the value of this LL is increased by 1.

Further, step 18γ branches to step 188 when N=2, and in steps 188 and 189, step 185
and 185.

Note that here as well, the value of LL is increased by 1 because this corresponds to the switching of program learning (corresponding to the fourth switching means in Fig. 6). Fig. 12 depicts step 119 of the learning control in Fig. 7 in detail. This is a flowchart. In FIG. 12, steps 214 and below are particularly relevant to the present invention.
If the data of the received third control signal is for controlling a single unit, step 214 branches to step 215 and subsequent steps. When LL=1, the program learning is switched (corresponding to the first switching means in FIG. 5), so in step 216 the drive device 73 (FIG. 5) is switched to rewind operation, and in step 218 Increase LL by 1. Even when LL=s, program learning switching (
(corresponding to the third switching means in FIG. 6), the drive device 73 (FIG. 5) is stopped in step 220,
In step 221, a display prompting self-evaluation is displayed. Also at this time, the value of LL is increased by 1 in step 218.

Next, when LL=e, the program learning is also switched (corresponding to the fifth switching means in FIG. 5), so the audio device 59 (FIG. 5) is switched to the recording state in step 223.

In this embodiment, switching between the recording state and the playback state after a sentence repeat is performed by storing the recording and playback state, but the storage capacity 111 can be reduced by switching based on the value of the progress counter LL. In addition, considering the large flow of program learning, the recording and playback conditions are clear, which has the advantage of making it easy for learners to distinguish between them. For this purpose, it is only necessary to set, for example, recording when LL-1 and playback when LL=3.

Although the above description has been made using a cassette tape as the magnetic tape, the present invention is not limited to whether or not the magnetic tape is contained in a magazine. In addition, although LEDs have been used for various displays, the present invention is not limited to the parts used for display, and can also be realized using other display systems, such as liquid crystal displays or printed materials. can. Furthermore, although the embodiments have been mainly explained using a microprocessor, it goes without saying that the scope of the present invention may be realized even if part or all of the microprocessor is implemented using a logic circuit or the like.

Effects of the Invention The present invention includes means for rewinding the magnetic tape while detecting signals recorded on the magnetic tape, and trunk selection means capable of specifying the signal detection track from the outside. and a means for canceling the rewinding state and switching to the recording state when a blank part of the magnetic tape or a specific signal continues for a certain period of time or more during the rewinding of the track. By providing a means for selecting a trunk outside the blank area or detecting a specific signal, and switching to recording after cueing, various teaching materials can be used effectively, and this can greatly contribute to improving the learning effect.

Further, by providing a means for switching to recording when a blank area at the time of cueing or when a specific signal is detected twice, the context can be sufficiently recognized.

Furthermore, since you can study with more leeway, it contributes significantly to improving the learning effect.

As described above, the present invention is extremely useful and can significantly improve the learning effect in learning using magnetic tapes.
